Ras Pi / Arduino Projects!

Anyone doing anything with a Pi or Arduino, etc? I'd love to hear! Some people have bots running on them, or have them used as a piratebox, or connected to mesh networks, or use them as proxies, use them in controllers and robotics, drones, and much more!

I have one sitting in my drawer for a long time. I'm thinking of making a pi-hole and piratebox like welcome page to have fun with the neighbors. There are many cool things to do, I just have to find the time!

I create a server minetest on my raspberry 4, if the server does not work or if I ever get tired I think I would make a server to host my files

I turned my Raspberry Pi 4 into a usable desktop replacement. Pic related. I have an RPi3 being used as a media center on a smartTV that is on a LAN only. I have another RPi3 as a Pi-Hole (but it's currently not in use.) I am slowly working on turning that into a portable firewall, (and with a few other functions I haven't decided on yet.) for my laptop on public wifi. My third RPi, is currently being used as a development server for this project a few acquaintences and I are working on. I'm also planning on setting up another Pi with a few externals to setup rsync to my desktop once a day.

Got one to run Octopi on my 3d printer. One is set up as a photo booth to bring to festivals and such. Got one to watch birds and monitor the soil in the garden. A couple to run an art installation on a bunch of old CRTs (native composite video out!). Got a couple more sitting around for various ad-hoc projects or what have you.

>>3478 How is the outdoor node encased and powered?

>>3474 I've been playing around with a Go-userland OS for the Rpi3 called gokrazy (https://gokrazy.org/). It has a Linux kernel under the hood and literally everything running on top of the kernel is written in pure Go and statically compiled. It's not really intended as a desktop OS, but it's a fascinating concept for a server OS: every single non-kernel program is memory-safe. That's an entire CLASS of attacks that this OS is inherently immune to. I'm working on adapting the concept to more powerful server hardware, just for fun. It's slow going but I'm learning a hell of a lot.

All of the fun happens with the GPIO stuff. You don't even need to be that great with programing because there are so many examples available to try.

>>3481 It's not; just have some long cables / USB extensions for the peripherals. The computer itself is in the garden shed (which is wired up to the mains) and has some wires trailing out of the eaves, sealed up with silicone caulking. Potted connections to the soil moisture and weather sensors, etc in epoxy. The webcam is inside a little birdhouse which is sheltered under the eaves and fairly watertight itself, so I don't worry much about that one. Plus, all the components are so cheap I figure it won't be a large expense if they wear out after a few years. >>3483 Mostly agreed! Though there is some fun networking stuff to do as well. The community really makes it easy to branch out without having to sacrifice too much focus on your main interests.

I made a little hash-cracking PoC with Arduino (and a host machine) to show how to use Serial communications properly, using Python to actually do lots of the logic checks and wordlist processing and Arduino to actually do the computation/hashing part. I can upload a guide to hackaday or something if anyone's interested. It's all self-contained on the Arduino, no shields or wiring needed, just a computer with the Python3 runtime and a cable to connect the Arduino to PC. Works fine on any arduino board AFAIK. Probably easily portable to ATTINY85 or your other favourite MCUs. It can also be easily changed to also do wordlist processing with a MicroSD shield, which would also probably increase hashes per second (sits at around 150H/s for MD5 @ 115200 baud rate.) As far as I can tell, I can probably get up to a KH if I port the code to C rather than Arduino and get rid of 99% of the Serial communications between host/board by using the shield.

>>3698 Should also note that if I port to C, then I can also upload it to an STM32 board or something, which will compute about five times faster than ATMEGA chips. Clustering is also possible if I use the RX/TX pins, but then that also decreases hashrate due to the transfer speeds between chips.

I'm thinking about making an mp3 player with an Arduino nano using a DFPlayer and a 5110 screen do you think it would work I don't have much hardware experience mostly been a software dev

I'm trying to figure a way to get a Pi into my car as a stereo/headunit, but it is a process: mounting, radio bezel modifications, speaker wiring, things I've never done before. I have a screen, but need to find a DAC for the speakers and software that can do maps navigation with OSM. Does anyone know how AOSP handles with a DAC? Would be the easiest way to operate a touchscreen and I could use OSMAnd.

>>3705 Im pretty sure that for OSM you are gonna need android or an emulator, I'd say, take a look at anbox. As for a dac, I am pretty sure there is one in your pi, it has a line out right?

>>3706 It has 3.5mm out, but the audio quality is real noisy if you dump it into an amp straight out. I found a HiFiBerry hat that seems to do what I want, but I'm not sure how to rig that up and also do display out through GPIO to the touchscreen too. I'll check out anbox, thanks!

Is using a rpi 3B+ a bit overkill for pihole?

>>3709 Using a Pi for one simple project is usually overkill, yes. Especially when it's arguably one of the most powerful models out there. A Pi-Hole will run on a PiZero/W without any hiccups, so that should be all you really need as a barebones. Doesn't mean you can't use the same pi for something else though. Maybe set yourself up a cool website on there or something desu.

I want to implement HTCPCP on a real Mr Coffee drip pot using a RasPi but I have no idea what to send to the Mr Coffee control board or heating elements to get it to work. Unfortunately, I don't have access to a oscilloscope. What should I do to reverse engineer this thing?

>>3709 Your router probably suns some sort of sinkhole dns already, there is no need to use a dedicated hardware for such simple task.

I don't have any microboards, but I did order some copper clad boards and ferric chloride today to make my own circuits. Does that count?

>>3719 It doesn't really matter what the thread is about, if you etch your own boards, it is a win.

>>3717 What sort of mr coffee are we talking? lots of timers and automatic doodads, or just a start button or switch? Two options would be just locating and tapping into the wire that makes it go (for example by looking for the wire that goes from the timer to the MOSFET/relay/TRIAC) or ripping all the automatic circuitry out and replacing it with a relay. In theory it's all PTC heaters so chance of catching fire should be tolerable. The hard part may be finding a place for the pi where it won't be damaged by water or heat.

I used mine to do some ssh tunneling to bypass the oppresive firewall of my last job, but I recently moved and I can't figure out how to connect to it since I'm behind a NAT right now. At this very moment it has syncthing installed so I can share stuff with multiple laptops that I have. Think of it like my own personal google drive.

>>3726 Yeah. Like if all you want to be able to do is start the coffeemaker, you could bridge whichever switch with a relay wired in parallel and have the pi trigger the relay. Not elegant or sophisticated, but it wouldn't require any further reverse-engineering. Considering you'd still have to put in grounds and water manually makes me question the utility of such a internet thing, but it's not my place to question why. I assume you have your reasons.

I have been sitting on a pi3 for a couple years now. No case for it cause I'm broke than the joker

I'm trying to make a security camera that also makes facial recognition and send me notifications through an app saying who is there, and if it is someone unindentified it is supposed to call the cops in 3 minutes if I say nothing about it.

>>3728 Do you have a private IP address, or is it your router NATing your traffic? - is port forwarding an option?

>>3951 >>3728 Reverse dynamic dns

i'm not sure what to do with my arduino but i use my orangepi as a seedbox, pomf clone and vpn gateway to my home network. never really been good at diy since my hands grow out of my ass.

>>3478 >Got one to watch birds and monitor the soil in the garden. I'm really interested in that one, like a lot. Could you tell me a bit more?

>>3707 Pretty late, but might help someone else out: You can install Android on a pi, I haven't looked much into it, but MagPi and a quick search has shown EmteriaOS as an option, don't know about others

Arduino stuff.

>>3956 So, just wondering, has anyone messed with the osmand source code here? I kinda want to do the, integrating osmand in a car thing, but with some extra information from osmand behind the steering wheel. I have pretty much zero java knowledge so I was thinking about finding the info I need, add some stuff to write that stuff to a file, so it is outside of this java environment and then bring it to where I want it to be using something like a C program inside of termux.

I'm looking to build an USB oscilloscope, however, I'm lost at what kind of MCU/MPU to use, I'm looking for a low amount of GPIO pins (only for a bit of control and for 2 channels), high-res ADC and a sampling rate about 2MHz, if it is powerful enough for an FFT + Window thats also alright, however, most heavy-tasks will be handled by the USB-Host.

Anyone tried to do something along the lines of interactive digital signage on the RasPi? I want one of three videos to play onscreen based on user input (buttons/sensors). It's not the IPC input-sensing part that's screwing me over, it's the fact that I've yet to find a reasonable media player for the job. All of them have no means of going from one video to the other without some sort of noticeable interruptions. Ideas?

>>3973 Gapless playlist and random playlist entry switching? Computer Science Student Way: Play all three videos in window manager, switch window focus from one to another based on button press.

>>3477 >My third RPi, is currently being used as a development server for this project a few acquaintences and I are working on. How do you make it accessible to them outside of your network? Do you have a fixed ip or use some kind of dynamic dns?

My pi is currently being used as a hardware firewall/router/DHCP/dns for my home I don't trust ISP hw

>>3978 Why can't one simply port forward to traverse nat

>>4009 port forwarding is half the equation; the other half is keeping those who want to reach you up-to-date with your IP address when the modem reboots and your ISP assigns you a new globally-routeable IP >>3974 this is actually kind of an OK idea since a window manager is a lot more likely to be able to mux between two streams of display data (its "ONE JOB", as it were) within given parameters than a media player, whose "ONE JOB" is to play the media itself

>>4010 https://github.com/ddclient/ddclient/ - get a domain from a provider that is supported by ddclient and you’re golden. It’s about as easy and reliable as dealing with dynamic IP addresses can be.

>>4011 using providers like afraid.freedns.org you can just get a token and run a get request using curl with the aforementioned token in the url. Automation amounts to periodically calling this oneliner. I don't get why ddns has to be this overengineered.

>>3474 I bought a zero and many devices with it to make a modest laptop or cyberdeck by am too much of a bum and lazy/scared/incompetent to finish it so it just lays there. >sd with lakka (can play gameboy(color), nes games but nothing more and was sad snes was not great emulation (should have bought a pi 3 but even then psx wants bin/cue and I have iso/img and needs network to install bios of which is inconvenient) >sd with rasbpian and backed up files for more modest computer usage potential (backed up roms and many books on it and reaction images but couldn't even help teach google AI turrets to not target store fronts so not much Internet capacity outside of wikipedia and IRC tier stuff and book reading txt files (I have 700ish txt ebooks) >lcd 3.5 inch but drivers bad because patent infringing version only 15fps approx >usb hub so 4 rather than one for devices (bluetooth notwithstanding) >usb mouse >tiny tablet keyboard just big enough to type on (bad punctuation area version and can't hit simultaneous buttons hardly for gaming) >battery of which did run the pi zero with usb stick, keyboard, and mouse all plugged in while projecting to hdmi monitor (but didn't test lcd) >cases (one has room for pin area to be shown, heat sinks, power cord (though not needed with battery bank) etc >sound card for usb so can use speakers or headphones, 3.5mm jacks of which worked surprisingly (it was only like 3-5 usd for the card and why did that work but not great lcd drivers?) >was going to buy glue gun and solder kit too so could glue everything on the back of the tablet usb keyboard case so could be laptop but wasn't worth it Image shows how it'd go together.

>>4065 Actually, I'd not glue the touchpad there, It'd go much closer to the main part in the center so I could still close it potentially with the magnet. Derp.

>>3954 Just a webcam, a PIR motion detector to turn it on when birds show up, and some soil moisture sensors for the garden. It has a web portal and logs soil moisture readings to it and posts images captured by the webcam so I can lookit the birdies. They so cute. I've since moved from that house, so I need to set it up again unfortunately.

>>4065 I'd use a pi 4. The pi zero w very quickly will frustrate with its lack of horsepower if you plan to use it as any kind of normal computer. Of course I'd really find a cheap used thin client if I were really motivated, but those also usually have a much higher power drain so it might necessitate a better battery solution as well and that's how BOM starts to snowball. Whatever floats your boat though.

>>4069 I'd use a 3 because 4 needs a fan. I am a bum and was on a budget last time I bought all of that stuff. I didn't even buy the pad there, I bought a cheap usb mouse. If you get it. I meant to replace it later after practicing with a 3. I need to get new sds and a 3 with a case and a new lcd that actually isn't cheap. I need the glue gun and not even really solder if I get a nice lcd pi combo. Some just fit right in. IF they work. It's just so I can get away from the CPU's with backdoors and the outdated windows 7 I currently use. Using these system on a chip computers. Rather than use old business laptops I'd like something I can pretty much repair as a bum. It doesn't float my boat no matter what though, as any option is bad for me. I'm not ever going to make something as nice as the eve raging modest business laptops I buy though. Even though I need to move on to linux. The old laptops are better than the pis currently and also are cheaper.

>>4071 I've put a big oversized heatsink with some good thermal paste on a 4 and made it run very stable while fanless. Not with dual monitors though, but I don't think you'd need that for your application. The pi 3 is acceptable; I've run a good media center on one. You need to mess with the graphics settings a good bit; more than just changing the RAM split. You need to enable some experimental drivers and a few other things I can't recall at this moment to make it perform in a decent way with a lot of media and modern web pages. But it's easy to search for tutorials for that online. I might come back and post one that I used if I can find it again. I believe you can boot off a USB flash drive now, which really helps with the SD corruption issues; I'd still just use an SD anyway for the R/W speeds and just be diligent with backups. Which is very easy on a pi, actually. Totally understand the avoidance of x86 chips. Don't blame you there. There's some good obscure boards out there that don't use x86 and are a bit more impressive than the pi, but they have their own problems and usually are many times pricier. I guess it's up to what your target specs and use cases are. Agreed about just getting an old laptop. Sometimes you can find those for a steal, and they already have all the peripherals and power supply figured out. That can really kill your low-budget dreams quickly if you're jury-rigging a portable machine from scratch. Ask me how I know.

>>4072 Pic related laptop of which is up there, I am currently on, it's a win7 I got from 4m0z0n. It's 1.6 ghz 2gigs ram. 32 bit. Only 65 US dollars. I've had a year and it works fine. Not perfect though. The video driver is glitchy, won't go into 4:3 with emulators. It's also locked out of the boot order, I couldn't get the password for it cracked. Removing teh cmos might kill it so I'm not doing that. Also the charger came broken but they gave me a second one for free. The sound is also very quiet but I have external speakers and or can use earbuds. But yeah, 65 USD for a win7 laptop that's more powerful than the pis cannot be competed with. No SOC kit can beat it as they are price gouged. Even if this drops dead soon the SD would have XD just as fast. I had the PI zero's micro SD break on me already when I was using it in a android I sometimes use that I found on the ground. No sim or anything, but used it as a computer. While reading ebooks off of it it finally corrupted. It'd been less than 1.5 years. some 16gb vilros thing. It's not like I abused the thing. I flashed it once, then put a ton of files on it. But that's all, then let it be mounted for a long while. fuarrrk I hate SD cards. I need to get a DVD-RW for my computer that's plug and play, they are not pricey, and backup all my files. I have a pile of DVD-R's anyway. What the files get put on and what software dependencies I use isn't my problem, I just can't decide what computer I want> I hate changing them when they break. Having a pile of SOC to just swap out would be great if I make the adjustment. LCD inverter dead? No need to try taking it apart, just get a new cheap tiny screen! And other reasons. Laptops are stressful to take apart. I've always been tempted to make a giant desktop laptop that's easy to fix that uses old 4:3 monitors and just slap it all together somehow. I'll eventually go insane and pic related from old desktop parts.

>>4071 Something to keep in mind though, the Pi has it's own kinda weird stuff about its platform. Like the ARM part of the computer actually being a slave to the ThreadX OS running on the GPU. It's kind of like the x86 Intel ME stuff but flipped on it's head, instead of having a tiny OS living embedded beneath your real computer, you are controlling the tiny OS running under the real computer (which the tiny OS isn't even aware of). The CPU isn't even on when you boot. I'd probably go rather for something like a Pinebook if I wanted to get away from the weird soykaf in modern computing. Not even that much more expensive than a Pi if you account for all the peripherals you need to add.

>>4080 x86 is just plum better and those are never tiny anymore. Things like sony viao with winxp on them are dead and I never get to have one. I've been looking into wiki Mini-ITX/Nano-ITX/Pico-ITX as they can have x86 while being small I read, but I don't know if they can handle older OS's and are probably a way to shove win10 bloated spyware down my throat. Pinebook isn't on a site I can get it from and 1.2 ghz is too slow anyway on top of that. I'll find a motherboard no wider than 5 inches eventually that can either run win9x - win7. Or I'll get used to having lakka and raspbian annoying me on normal SOC. I use androids off and on anyway. Right now in fact I'm playing KOTOR on an android right now because my 1.6 ghz win7 netbook probably can't handle the real version anyway. Unless it can. My web is too slow to bother downloading it twice. I found a cell with 1.8 ghz on the ground so I knew it could handle it. My controller keeps getting disconnected though and the application acts like it wasn't to stay on forever and force stopping things 50 times a day is annoying. I hate modern technology. Rasbpian has systemd and people talk bad about that. From my experience modern Linux is super slow in comparison to older windows. I just don't know anymore. At the end of the day AM4 cpu will be laughing in my face and stuff while I assumed I could get win7 to work on things like this. I won't try making something myself with some weird motherboard. I'll use lakka and raspbian eventually and leave win7 behind. I never do that much with my current win7 netbook anyway. You know I find it ridiculous how slow the zero was though. To not be able to run snes properly of all things. My windows 98 computer was fine with windows 7 then you run into THIS modern day madhouse. I just want to hide under my covers. when I run emulators on my windows 7 it only uses half it's resources and that's half of 1.6 and less than a gig of ram. You'd figure 800 mhz and 500 mb of ram is where these things would have gotten good but I was disappointed. Not that I know how programming works, it just seems so ugh. Daydream image semi-related.

>>4083 By viao I meant those sony vaio mini pc things that are now still 500 usd and not worth it even if cheap with how they are designed. https://en.wikipedia.org/wiki/Sony_Vaio_UX_Micro_PC?wprov=srpw1_5 but whatever

>>4083 autism fuels me to add a part to the bottom for further conveyance

>>3474 That just marketing trash of crapware.

>>4085 >>4084 >>4083 >>4073 >>4072 >>4071 >>4080 >>4069 >>4065 Guy that soykafposted silly images back again. I read confirmation that in fact a mini-itx CAN work with the windows I want. So I'd do that once I have money. It is slightly large though, being nearly 7 inches square. Really that's not big though. It's only a bit over a lb without adding anything to it but people read books in the past that weighted 2lbs easy for hours. Sorry to hijack thread but I'm just saying I read confirmation that someone got win7 to work on one, so I was on the right track after all. 1.8 and 2gs of ram would be perfect even if slightly big. I wonder how heavy it'd get once completed though? I wish I had money becuase they can be pricey. Sometimes 60-90, other times 200. >>4094 People like it because it's super tiny. And cheap consistently. Plus it's an anti-botnet thing to get away from intel CPUs I'm sure and people tell themselves that they can program them to do whatever they want them to in general. It's a control freak cheapo supercute chip.

>>4102 If you're willing to go with Intel x86 and Windows, then there's a few options besides the mini itx boards. Intel NUC boards are far smaller and come with a soldered-down CPU/GPU and thermal solution. You just slot in some laptop ram and an m.2 drive. Usually you can order those in a combo, but I'd shop around. They are not exceptionally cheap, but the lower-end ones are not exorbitant either. I have one that has 32GB of ram and a nice high-end i9 CPU. It's fast as ѕһіt, especially considering it's about the size of a drink coaster. It's basically a mac mini without all the mac crap. https://simplynuc.com/ If that's too pricey and involved, you can run win10 on a lattepanda. It's kind of challenging, but it works acceptably well. The support is pretty much garbage. You won't want to buy one with pre-installed windows; it's a gimped version. You'll want to get the linux version and install windows pro on it, which will involve a bit of massaging and coercion. You'll also have to find all the drivers and install them manually. But it's even tinier than the NUC (about the size of a pi) and fairly cheap, but not a bargain. As a bonus, it also has an onboard arduino with its own inputs and outputs in addition to some of the usual GPIO and a LVDS display connector and other such things. Put a new thermal solution on it or your windows experience will be throttled and sad. You just have to remove a little metal plate that looks like an RF shield, but is actually a heat spreader (with no heat sink which is lame), put on some actual proper thermal paste, and stick on a real heat sink directly to the dies and maybe a fan. Mine stays very cool and I run it fairly hard. They have since come out with a new model, which I have no experience with. https://www.lattepanda.com/ There are other, more obscure x86 SBCs out there. UDOO comes to mind. I have never used one. I'm only gonna recommend what I know for now. Avoid the so-called "Atomic Pi" like the plague. That thing is electronic waste trying to be hawked as a commercial product. Literally. Some company failed at making an over-engineered x86 IoT vacuum cleaner or something and decided to pawn off their existing stock by ripping out the mainboard and sloppily re-branding it as an SBC. It's dogѕһіt.

>>4103 >>win10 I projectile vomited. The mini-itx I can see for only 60 usd right now and it comes with the cpu, ram is always cheap, that's why I decided that one. Unless it runs out of stock and becomes 200 USD in which case I'll just have to choke down lakka and arm-lubuntu or something as a combo on a very breakable sd card. I hate the PSX needing cue/bin. I just can't stand that idea. Makes me hyper mad at Linux users. Like I said earier. Though making a soc work with a linux or two on an sd card is very easy indeed. I am more than willing to be on win7 but often driver issues are a thing with theses x86 computers trying to ironically have win10 when win10 can do arm. It's asinine and false advertising tier an annoyance. win10 is bloated spyware and I hardly like win7 as it is due to it not looking like a true classic gui like xp had. I miss 9x. My 98 from the early 2000s with a pentium III was fine for me and I miss it and merely wanted it to get smaller over time. I'm still mad they don't make browsers for it. That's all it's missing. I'm tempted to download opera 10 right now but a download link for it 404'd. I wonder how that'd play out browsing such places as here? So long as it's not filled with javascript and forcing google captcha then I bet it'd work. I'll keep looking though in case something conveniently neet-priced show's up.

>>4104 I only mention win10 on x86 to illustrate the board's abilities really; it's impressive since win10 is so horrendously resource-hungry :P It can technically do ARM, but it ain't good. Not that it's good on x86 either, but y'know what I mean. win7 is also vomit-worthy to be honest. Could always just jump on elinks? What are your computing needs other than web browsing, by the way? I'm curious. Btw if you end up going with ARM, there's a couple Odroid boards I believe (and probably others out there somwhere) that can boot off a USB3.0 drive and are way more stable and fast and don't corrupt their own boot sectors after a relatively short period of time. I think there's even one with SATA.

>>4105 Retro emulation like nes/gba/n64/psx/etc, irc, tube site watching, ebooks, torrenting, and that's pretty much it other than browsing. Androids and the like do all that but then I get an urge to run rpg maker 2003 or play swf files or play some obscure pc game like a touhou fanmade game and then I get an issue at some point. LIke right now I'm playing kotor on a phone and the text is too small and the Bluetooth controller keeps getting rejected. Win7 is like xp but less hackable as I understood it. I miss xp and 9x though myself. Only this past year or so did I move on from xp. IN 20010ish I was on 98 and a psp. Then a xp laptop only, then xp and android, now androids and win7 laptop. The psp I used to bring files back to the 98 desktop back then. I've always been a bum with no access often anyway. usb sounds nice elink?

>>4106 Gotcha. I mean if those are your requirements, I expect a pi 3 or 4 with an appropriate linux distro would be more than adequate. And significantly better than any windows version imo. Except for rpg maker, I think you might be SOL on that one without an x86 setup. And n64 emu. Could be wrong, though. You can deal with the SD problems with frequent backups; it's pretty easy to plug a usb sd card reader into one of the usb ports and have the pi clone itself on a regular basis. Solves most problems. Elinks is a terminal browser. Just mentioned it 'cause it seemed like you were looking for some kind of ultra-minimal browser that would work on any hardware, but I may have misinterpreted that. It honestly doesn't work for a good bit of the modern web, but most of the sites that don't work on it are garbage as far as I'm concerned.

>>4103 >Avoid the so-called "Atomic Pi" like the plague. The only article about it on hackaday is written by an incompetent retard who's drank raspberry soylent for too long. It's a x86-64 compatible computer with real-time clock, heatsink, 16 Gb disk, 2Gb of ram and gigabit network card. There's literally nothing wrong with it as for what it would be used for: a set up-and-forget silent low-power server, media player and game console with upstream operating systems support. Raspberry Pi and it's clones are good for one thing only: as educational programming computer in ecosystem of pricey adafruit expansion modules for it. Pretending that it's an epic industrial computer for managing something other than a bunch of LEDs is a huge misunderstanding in many people's minds.

I tried Kodi on an "Orangepi One Plus" this week. Played H.265 2160p flawless out of the box. Not bad for ~25$. Only thing to add was a heatsink.

>>4109 There's literally pis in duty in industrial settings all over the world. Gajillions of them mounted on DIN rails and such. You don't need to use any adafruit expansions to get good use out of them. The Atomic Pi is full of weird flaws. It's pure ass. I've known people who got them and seen some of its fuсkery. If it seems too good to be true, it probably is.

>>4109 >There's literally nothing wrong with it as for what it would be used for: a set up-and-forget silent low-power server, media player and game console with upstream operating systems support. at my old job we used Intel ComputeSticks for one of our products. We had to run every unit continuously for over a week before shipping them out, because some of them had weird hardware errors. Enough that it was a big fuarrrking deal and people got in trouble. We bought them directly from Intel. The moral of the story is: specs aren't everything, it is very possible to fuarrrk up making a "set up-and-forget silent low-power server etc". >Pretending that it's an epic industrial computer for managing something other than a bunch of LEDs is a huge misunderstanding in many people's minds. It's an all-purpose microcontroller breakout board.

>>3973 >>3974 i think the key is having three codecs running at the same time, and then switching between their outputs. a wm is not a bad idea, but maybe you can do it with some sort of streaming player?

bump

I setup a ((functioning)) nas system with two old Raspberry pi 3b+. Works great with content at around 12 GB~

>>4291 Looks noice. Could have you done that using only one rpi?

If you would build raspi cluster would you connect it using LAN or potentially develop or use 3existing kernel code to do communication trou GPIO?

>>3956 Also late, but I ended up running Raspbian on the Pi and setting up an Emby server that I connect to over localhost. Its got a 7" touchscreen on it and the web interface scales down nicely for touch input. Very pleased.

>>4291 >>4293 I don't understand either why there would be two rpis. Memory issues ? So Jellyfin serves as a media server ? Can it play media on the rpi directly ? I'm using mopidy on my rpi, which is also plugged to speakers. This is much nicer to play music since it won't stop when my computer is shut down. I recently found out about sshfs, which is just very simple and convenient if I want to access files on the rpi.

I was thinking of trying to use a pi to make a small laptop. I work in an electronics store so I might have access to most of the things I need. The biggest two problems I've ran into in the planning stage has been the power source and the keyboard/mouse. I'm thinking of using a portable battery charger for the main source of power, which I think should last for a good while. The main problem is finding a way to know how much charge is left. I've got no idea on how to do that other than use an opamp comparator and set it to a point where when a certain voltage is reached on the battery an led will light up, signalling my battery is low. The other problem is a keyboard/mouse. I want a small keyboard/mouse combo. The only ones I've seen in my store are bluetooth only. I want to try and find a way to make it not a bluetooth device. I won't be able open up the back, solder things together and make it work due to lack of soldering experience. I doubt that even if I did have experience I would be able to do so since it was designed to be used as a bluetooth device. A possible solution I thought of would be making a keyboard using the GPIO pins on the board, programming it so that when certain pins are made high they correspond to a different key and having a touch screen lcd to act as my mouse. If the store sells some sort of touch pad I would see if I could use that as a mouse instead. For now it's a huge pipe dream since I don't know how to do any of what I said, nor do I know if any of it is possible. It's more of a goal I've set for myself as a way for someone who doesn't have much experience to learn a bunch of different things to make a usable, tangible, object.

>>4316 If you get a 4 you should have no issues in terms of hardware, but between the cost of a screen, power supply, keyboard etc. you are probably better off buying a used laptop especially if you want to actually carry it around.

>>4317 This. Especially if you live in the US. As a European I can only look in jealousy at the prices you pay for used hardware. Here people want you to pay for their sentimental value or something. I have a Pi 4b which is my Pi-Hole/Print server/Syncthing node/Torrentbox/Webserver and a Pi 3b+ with a Hifiberry which runs Volumio.

Does anyone have a recommendation on a PirateBox image or all-in-one package? I assume someone has made one and it's not necessary for me to install an imageboard, upload form, etc all separately and manually on the device.

>>4317 It's more something to expand my skills. I have a good amount of theory under my belt, which means little in terms of application. I think making a shoddy laptop would serve me more than messing around with breadboards, or doing exercises in books. That's not to say I'll never do those things. It's more that having a concise end goal will motivate me far more than just trying to complete a textbook.

>>4319 assuming you're looking for a raspberry pi based image, I've always used the one on the website - https://piratebox.cc/raspberry_pi:diy

I've got this stuff plus a sautering iron and a Pi 3b. What should I do with them?

>>4318 Not him but is THAT why those system on a chip computers of Britain took off? Makes sense. I've always opted for used business laptops. They literally cost less than the price gouged pis once you've bought all the stuff to go with them.

>>4323 Maybe go on adafruit or instructable and do some lame tutorials or else try >>4332 and see how much of it you can get in there, who knows you may surprise yourself

>>4318 Selling used stuff in my country is comical. >thing is worth 100, sell at 50 used >HEY CAN YOU SELL IT AT 5 >no sorry, I can do 45 >AH SORRY NO I HOPED TO GET IT AT NO MORE THAN 5 Then they sell something used themselves and it's like 10% above RRP It's like they're too stupid and greedy to understand how it works on a basic level, they just hope that some idiot falls for their little scam. Coincidentally, everyone here is wearing those respirator masks with the hole, the ones that spread germs outside but protect you more than the regular ones. It's interesting how the US are money-obsessed but have a respectful mindset when it comes to selling used (or so it seems, yard sales etc. are a cool thing about the US).

I figured I'd throw this here, as I think it doesn't deserve its own thread (and the CubieBoard2 seemed like a cheap alternative) : I'm planning on making some of the Active Electrodes on OpenEEG and using pic releated (cubieboard 2, linux compatable) and using its I/O and ADC converters to read the Electrode data, write it to a hard drive or SD Card. Nothing too complex and OpenEEG has most of the data I needed and the ability process and filter bad info or alert to bad electrodes. I want a EEG device you can wear. Something I can sew into something and have it comfortable and not as off-putting as actual electrodes and a backpack to process

>>4323 This picture loaded sideways for me. How does that work?

>>4369 That's an interesting question, my first bet was that it's APNG, which I somewhere learned gives you a lot of freedom for custom thumbnails. But that's shortsighted, it's not only a genuine JPEG, but why would anybody go through the trouble. Then I found out, apparently digital cameras tend not to go through the trouble to orient their thumbnails correctly and instead specify orientation in EXIF, upon which I checked out the EXIF header. Indeed, the following line appears: Orientation : Rotate 90 CW I'm no expert, but there is also a field in the EXIF header for the thumbnail itself, so it's reasonable the camera just didn't bother post processing the actual image. Unfortunately lain's image does not exhibit any GPS data, so I can't say where the image was taken, but I can say he used a samsung sm-n960u as a camera, which translates to a galaxy note 9. Incidentally, at the time of shooting he was supposedly running the feb 2020 security patch, codename N960USQS3DTB1. What's more, assuming lain has his clock set correctly, the image was shot at 2020:04:05 00:28:26 localtime. I guess if lain uploaded the image within the same hour, which seems reasonable judging by the 2020-04-05 05:34:23 timestamp of the post, then you can infer a timezone also. I was going to say, remember to strip your EXIF data, but I guess the image's orientation would no longer be correct...

>>4316 I looked for stuff like this to put as a laptop keyboard, yeh, its Bluetooth, but it seems that small wired keyboards are dead as a concept

I just try to integrate a Pi3, a 7 inch display and some li-ion bateries into a Compaq KB-9968 Keyboard. It´s more on the crafting and cutting than on the programming side. I will use it as a minimal setup to safe myself from distractions, while enjoying some C. I will post an update when everything is up and running. If you have questions ore cool ideas let me know.

>>4601 I like it. Why not put a pi4 tho? Or like a lattepanda or NUC depending on budget. But in any case, I respect the beige and the dremeling. Godspeed

>>4602 keyboard on that actually looks like it's nice. >>4316 I've been thinking about this too. I really want to make a "palmtop" kind of little thing. But Like you said every single keyboard that's close to the right size is bluetooth. I hate that. I'm not going to build a device that connects to its own parts with bluetooth, it's just idiotic to even imagine. I think you'd be better off going with a microcontroller and making your own keyboard. and by the way soldering is really easy. just do it man. so first you'd have to source some switches from digikey or mouser or something. problem is figuring out what switches will make for decent keyboard switches. then once you figure that out you'd have to make your own matrix keyboard and wire it up which might not be too bad. Then you need a screen. 4:3 is of course my favorite aspect ratio but it's too tall to work as a palmtop. But, it would work alright in a small laptop size. the thing is nobody makes those screens. everything is crappy 16:9. if you look at palmtops when they were popular they're all much wider than 16:9, if it's not that wide the form factor doesn't work as well. So you're basically stuck paying $50 for a crappy litttle 16:9 screen anyway. At least you can get these with touch panels so maybe, you wouldn't "need" a pointing device. Still, I would like to have a pointing device anyway. A trackpoint style nub would be nice but again, sourcing this is hard. I saw some low profile joystick type things on mouser but the minimum order is 2000 units. So that won't work. And a trackpad is too large for a very small laptop. So if I made a palmtop I'd have to first, make my own keyboard, then settle on a subpar screen which would mess up the form factor a little bit. Then most likely ditch any mouse device in favor of the touch screen and stylus which is a bit of a compromise but maybe not so bad. Then on top of that you will need to design and make a case and figure out a battery solution which will probably suck. So for a small laptop or a palmtop form factor you're going to be in maybe $30 for the pi, $60 for the screen, maybe $30 for the parts to make the keyboard, who knows how much for the battery. you'd be better off spending $60 on a used small thinkpad or netbook and call it a day. if you had the time and money it would be a nice project but it would take a lot of making things yourself.

>>4316 >I was thinking of trying to use a pi to make a small laptop. FWIW this is essentially what the pinebook is already: https://www.pine64.org/pinebook/ Not that DIYing something yourself is without merit. Sounds like a fun project.

>>4603 The choice was made because I had the Pi laying around. It was formerly used in an emulator station. I was surprised how easy it is to get some satisfying results with the dremel, now I just need to figure out the Li Ion Charging circuit and the keyboard to pi connection but then I am pretty much done.

>>3474 >>4609 Colegue of mine owns a pinebook and says it literally falls apart in hands.

I want to use my pi as a media server, primarily for audio but as you all know, the audio output is like kicking dead whales down the beach pretty fuarrrking bad. What would be some decent but cheap solutions? USB DAC? I looked at hifiberry but it's a bit expensive and my speakers aren't good enough for something like that

>>3474 I use a smaller Pi to keep a weechat session up and as a syncthing node so I don't have conflicts when I use different devices at a different time. I have a script that writes my public IP on a file so I can access it at any time from my phone via Connectbot when I want to (yeah dynamic DNS are a thing, I don't care). I would love to get another to host a phlog or Ghost blog or IRC server or dreamiest of dreams, an imageboard / textboard about my niche interests but I don't want to waste time on something that nobody will ever look at and in the imageboard's case, gore/CP spam. I don't wanna see any of that stuff for a second. If I lived in a place that wasn't a concrete soykafhole I would set one up with a webcam and a bird feeder. I love stuff like this https://www.allaboutbirds.org/cams/cornell-lab-feederwatch/ I would donate but I'm 150$ under right now.

>>4643 at a hundred bucks, its not particularly built to be rugged, although it shouldn't be falling apart too easily either. Is it actually that bad?

>>4693 I would assume any driverless USB DAC would work. I've used an $8 Sabrent USB soundcard on a bunch of stuff, but never tried it on my pi. The Topping MX3 could work and be both the DAC and speaker amp, but it's more expensive. I have the latter's USB plugged into a PS4 slim because Sony got rid of all the audio outputs on their consoles...

>>4695 Of course there's also the question of how well the owner treats it. As someone who can't really afford to replace things at the drop of a hat, I'm constantly amazed by people who casually mistreat electronics. Keeping laptops in backpacks with no protective padding that they just drop on the floor, throw phones onto tables and are surprised when they slide off the edge and get a cracked screen, etc.

>>4693 >I want to use my pi as a media server, primarily for audio but as you all know, the audio output is like kicking dead whales down the beach pretty fuarrrking bad. This is really unfortunate because I had the same idea.

I was going to use my Pi to make a bitcoin hardware wallet, but I ran into problems: >not friendly to bare-metal programming >RNG isn't documented + first few bytes of output don't seem totally random >all screens except the expensive proprietary one block the UART pins, which I need At least it still works as semi-decorative tech clutter

>>4781 Just get an stm32 or something like that

>>4788 I was using a stm32f3discovery even before I was using the pi, but it was so weak it couldn't sign transactions even if I left it on all night. I guess I probably just need the f4, it's more powerful and has a lot of features that make it good for a wallet. This guy reccs it: https://www.youtube.com/watch?v=AgOqTGeDrac Wish I had found earlier to be honest, I've been wandering aimlessly for almost a year now. I just want to work on something else but I'll have to seppuku if I can't finish this fuarrrking god damned project.

>>3474 I have a microft mark 1. Got it for free from a local hackerspace. I might either update the image for it and play around with making microft skills or take the RasPi out and use it for something else. What do you lainons think?

Hey Lains electronics newb here, how do the ground pins work on the pi? my power cable has no ground line reason im asking is because i want to put it in a case and disassemble the power supply and solder it to pic related should i solder one of the ground pins to the plug? also are there any materials that the ultrasonic sensor can penetrate? maybe acrylic glass or paper?

>>5099 "Ground" pins on Pi are negative pole, they are not AC ground pins you imagined. They are needed for signal wires to work since electric current travels across circuit and needs to return to source. When you disassemble the power supply, it will have two wires supplying 5 Volts through micro-B USB cable, and two going to the plug pins.

>>5099 When it comes to something ultrasonic sensors can penetrate, try different mesh materials, just things with lots of visible holes. Something that won't reflect too much by itsself.

>>3474 Using my Raspberry Pi 3 as an ArchiveBox instance. It's nice to have a little time capsule of all the interesting articles and websites I come across. I've been wanting to do a crude implementation of smart glasses but obtaining a screen for it is the hardest part. Any ideas?

Here's my stuff: https://github.com/NEONTEC75 A set of Nixie shields for Arduino with a library.

>>5174 https://store.vufine.com/products/vufine-wearable-display-2

Can i buy an open source WiFi outlet? All the ones I see say works with Alexa etc.

>>5205 I don't think an off the shelve product like that exists. But it is a relatively easy project to make yourself. Just get a relay, an esp8266 and something to provide (I think 3.3 volt) to that esp82666.

>>3474 I use my raspberry pi 4 (1gb) as a local NFS server and for periodic rsync backups from my server. I have it connected to my server over openvpn. I can access files on the go. It's a neat little apparatus. Eventually I'd like to purchase one of those hard drive hubs that connect over USB3. Setup a raid with 4-6 drives. The power delivery on the PI4 isn't strong enough on it's own to power more than one 2.5" harddrive

>>5205 look at a travel router compatible as a piratebox

>>4608 >and by the way soldering is really easy. just do it man. Not that guy but it's not easy for everybody.

>>4694 Hey I like all of your ideas, I like your post the most of all the ones itt. Did you yet get around to hosting a blog or forum? I highly encourage you to try it, even if you don't think anyone will care. It's a fun and useful experience and depending on your interests I might become a reader of your blog

Best SBC to try OpenBSD?

>>4693 >like kicking dead whales down the beach I keep forgetting what this means even though I've been filtered saying whatever it was myself. >>5924 Would not freeBSD be more cyber? I thought it was less botnet, and the freeBSD site has sd card images for: RPI-B BANANAPI CUBIEBOARD CUBIEBOARD2 CUBOX-HUMMINGBOARD GENERICSD RPI2 PANDABOARD WANDBOARD PINE64 PINE64-LTS RPI3 Out of all of that the rpi3 seems the most popular, so I'd go with that. Not that I have much of any experience.

I wonder if I should overclock it? Hopefully when my lcd comes in the mail, image related, I'll be able to make a tiny pda thingy. I have lots of peripherals that work with it. A sound card, bluetooth headset, spare solar panels for 5v, a battery bank that powers it up (2a in one usb out, another spare for 1a 5v out, and has a tiny solar panel on it), 7'' tablet keyboard, mouse, usb splitter, now a tinnier keyboard and really tiny lcd screen through composit that won't need drivers is in the mail. I'll put it all together and it'll be a really ghetto thingy. \ I'm about to finally have 'built' the cheapest computer you can build from new parts. The soldering part will be the hardest for me, as I think I can whittle the lcd and controller shapes in place well enough, and holes for sub access on the sides of my cigar box. Glad it's working out finally. I can't wait to play gameboy games on it and or read txt books on raspbian! Present Day, Present Time! AHAHAHAHAHA!

>>5936 accidentally forgot to crop the image and label an item

>>5936 >sub access I meant usb access on the side. Also I'm cutting a hole in the back where the controller/keyboard won't be for the solar to stick out, not that it'd be practical. It still seems the thing to do.

>>5936 Congratulations on building a custom UMPC. Always remember that you can easily fix and upgrade it unlike modern products.

>>5946 It's not easy to fix when you're a neet with precious little equipment. i put a lot of effort into ruining one soldering pen tip then finally got the composite soldering up, the gpio pins, then the wires, but one wire came undone while I was trying to find out if I could get lakka's nightly build to use composite, as with noobs it won't work. It worked with nightly of lakka, but then I broke it without realizing it while troubleshooting back and forth. It froze while messing with the audio before that happened, and I thus keep reflashing and reinstalling os's on my sd cards, of which will probably eventually break them. Why would lakka have issues with composite when it's a retro emulation distro? I bet getting sound to work will be impossible. Also, I tried my sound card with raspbian and it was awfully damaged. Weird whining noises and barely any sound, so I only have the bluetooth headsets for that. I don't know if either would work for lakka. I may have to get a 50+ hdmi monitor with speakers (I hope) that's like 7 inches to finally have a 'form factor' pc, and it won't be ultra that way, with the audio issue. Even if i get a new os to work I have to go and delete the other backup up os's for the sake of the better one, on all of my redundant drives. I'm pretty sure I hate this. No congratulations are needed. It's not completed to the point to where it'd be mobile of which would be the whole point of a soc if you ask me.

>>5948 Hopefully an hdmi audio splitter thing will work. If I get one and it does, death the usb flash drive looking cheap audio cards that you can buy, and are in that image. Or maybe installing emulators within raspbian is feasible, stand alones. I doubt it. Hell of a book reader in the meantime. Best mp4 player evar. I might consider it cool enough if I could get a raspbian application to use midi files that I like to listen to while reading txt files. I'd like to think stuff could be on par with windows media player classic but both android apps and what comes with raspbian fails that I have seen. I wonder what 'player' would work. Or maybe I should just get mp3's....

>>5949 the screen and mini keyboard/mouse and pi work via the sol bat. Now if only sound worked (barring raspbian). the sceen is not that blurry, it is a gare

>image doesn't have mini keyboard plugged in It does work though. And that image lacks the blackweb bluetooth headset that works with raspbian, I meant to have it in the image but it's not important. I guess I will be forced to try to add emulators within raspbian due to lack of funding for an hdmi splitter, or resistors and such for soldering it from the gpio pins. I also forgot to have the soykafty card for audio that's damaged in the image that used to work with raspbian but now sounds possessed, but it's something not worth seeing either. I figure if pocketgo's had emulation on it's debian it can't be that impossible to get them running through the systemd bloatware that is raspbian, as debian likely was systemd for that thing too. The power of the pocketchip was on par with the zero and I know that the zero can't use a non-systemd debian, it's only post systemd and that systemd is slow of course....so yeah. Or maybe retropie can find a way to connect to the bluetooth headset as raspbian does. I'd rather do that than XD the console all week long while failing as I know I will trying to get emulators to work through raspbian. I read about getting the retroarch working through it, it didn't sound easy, and I don't know if that'd be any different than just having it on another card anyway if it's not a stand alone like a normal computer would have, why would it work? The sound. I'm too much of a forever-noob to decide what to do with my overpriced mp4 player, of which is what it effectively is currently. I'll probably give up again and let it set for another further 2 years. The pi and it's bought peripherals, as I've had them, most of it, for a few now. Back when I first tried it I realized the 3.5'' gpio pin lcd would not work with lakka, and that I suck at soldering and had no soldering iron at the time anyway, and also that layers were missing in snes, of which just had me pure bummed. My go-bag being complete but only having one backup phone and an old tablet to take with me into the woods potentially is what motivated me to spend a little 'gift money' on fixing the pi zero to be a mobile device finally. So at least I could have a forth book reading device so far. That's the story about me and this zero. Too much discord in the 'house' (it's an apt) cause me to want/need to possibly live in the woods and such discord doens't help me do diy console stuffs as I'm slightly dumb and adhd to begin with without such drama. I hope another OS will work for it as a new sd came into the mail anyway. There's two I've not messed with for retro gaming. If not I will try to concentrate on getting stand alone emulators to work, preferably 3 (nes/snes/gb(C) (as I know those three/four should perform well enough (though wish gba could))), to work through raspbian. Or just fully retroarch through it, I guess. I know that retroarch through android is extremely slow on more powerful devices for me, so I guess in the sense that I doubt I'll even try that. Unless it boots up while turning all of that raspbian stuff off, in which case it's the same thing as dual booting I'd imagine, but I just don't really comprehend it to be honest. Once sound works with an emulator I'll cut the things, glue them, screw them, etc, into the cigar box. /blog

>>5951 Raspberry Pi doesn't have composite audio output, just video. Usually audio output is from the 3.5 mm or HDMI. Try gluing a small speaker to the case and connect it to 3.5 mm. If you use a Raspberry Pi Zero instead, get an audio output hat or a good USB audio card. In Lakka, you then just configure the audio output through USB audio card instead of HDMI.

>>5952 I'm not sure how to get lakka to choose which audio device is which. It's cryptic. And my audio usb card is broken anyway. Raspbian it outputs a constant wailing noise that supersedes anything being much heard. Perhaps there's interference. Maybe I should wrap it in aluminum foil. I swear it used to work fine 3 years ago when I bought it. Even if not, i can't figure out if it's even possible to get it to switch to it, nor a bluetooth headset for audio. There's one option for you to type something in it to ignore a device in audio, but I don't know what to type.

retropi is fun if youre bored

>>5952 >Raspberry Pi doesn't have composite audio output You mean seperate red and white jacks like TVs have? Those are called RCA connectors and it's trivial to adapt it to 3.5mm stereo. If you have some old headphones and a pair of RCA cables you don't mind cutting up you could make one right now.

>>5953 You can change the audio output device in both the boot config and the menu of Lakka, in options. Set the default pulseaudio sink to the USB sound card. Test your USB sound card on a working computer. You can also output sound using PWM GPIO ports if you really must.

>>5957 The guy with the zero here, I thought that you required: 2 x 10 µF capacitors 2 x 0.33 or 0.01 capacitors 2 x 270 Ohm resistors 2 x 150 Ohm resistors Female 3.5mm audio jack Via pics related. Or is that overdesigned? 1/3

2/3

3/3

>>5958 I have attempted to solder headphones to the thing but no sound is happening even though I dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4 Into it's config.txt at the end of the file lines of text. I don't understand how to use lakka's options either. I don't see 'pulseaudio' anywhere. Though it does have options.

also tried other things in the config.txt

>>5961 http://www.lakka.tv/doc/Audio-settings/ Just follow this guide, it shows how to change the audio device to the USB sound card. The PWM GPIO speaker output requires entering the rest of the commands on this page, not just editing config.txt https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero/pi-zero-pwm-audio

>>5974 Based on the gif there that I never noticed on that site, of which thanks, it simply can't detect my failing sound card. But I have an hdmi splitter in the mail now. I hope it doesn't give me another issue. The entering of the commands would be problematic if my win7 computer can't control the thing also, unless there's way to open the console in the pi zero itself that I didn't notice. Usb sound cards are cheaper so it'd be cool if it could see it as in option as raspbian could, but it has not shown up. Perhaps it's due to the damage. I just see the default drives to choose from and not any names indicative of an external device.

>>5975 https://www.lakka.tv/doc/Accessing-Lakka-command-line-interface/ All the commands should be entered into a Raspbian terminal or Lakka through SSH. Use your display and keyboard to open a terminal in Raspbian, and use another computer to SSH into Lakka. If you want PWM GPIO speaker output, the RC filter is necessary to reduce THD. It will still work without it, but only for 8bit chiptunes. Does the USB sound card work in your other computer? Be careful of HDMI splitters drawing too much power from the HDMI.

>>5961 oh, sorry i missed that you were using a pi zero. i thought you had a regular pi and didn't know you could adapt the headphone jack for use with other connectors. the thing you posted looks like a simple filter. seems like it would work, although idk how good of a dac the gpio pins would be.

>>5981 The USB sound card is detected by raspbian but has an awful noise it makes that drowns out most things you want to hear. It didn't used to do it so must be damaged. Also the bluetooth headset works fine in raspbian. Even if it's unusable it bothers me that it can't even detect it. I generally am on a win7 computer that acts like the zero is invisible or I'd have tried samba and ssh, but I gave up on that when samba never worked. I'd boot up linux's on the win7 but it has me locked out of the boot order in the bios. But I have an hdmi splitter in the mail so I guess that will have to be my 'diy' solution. Buying yet another peripherals. I would have bought all of those electronic parts, resistors and all, but forgetting the fact that I suck at soldering they end up costing more than the hdmi splitter and you still have to alter how the OS thinks so it will output to it and I have not much confidence with that either. I would have not went on about it but I was out of money and I'm thinking it will switch to hdmi monitor and ignore composite altogether if I plug an hdmi audio and video splitter into it. When I plug hdmi into it and composite it ignores composite. So if that happens my next issues will be what to put into the config to get it to stop that. Or, I'll have to buy a third screen for it. GPIO one was silly due to drivers, composite sound issues, then an hdmi one, the most expensive and large. One is only 5 inches though and is less than 40 usd right now, but I can't buy it without sending stuff back or else I'll get soykaf from my 'father' over it as I'm neet. It's silly how soykaf my life is. This is the third year I've own the zero and I've still not made it into a mobile device to reasonable satisfaction, and it being a zero should not have costed as much as it did so far. Nor should I have to have downloaded nightly of lakka to get the composite to even work, of which means I can't dual-boot with noobs. I'll have to tear apart whatever I make to switch from book reading raspbian to game playing lakka. I'd learn to use partition software but I know I'll not succeed.

>>5950 That solar battery seems useful. Where did you obtain it from?

To whom it may concern, the pi zero with lakka actually froze when I tried it with the hdmi splitter and so I'm sending it back for another sound card via usb I guess. Like the one I already bought that broke from non-use while sitting in my drawer. >>5985 Amazon. It charges itself very slowly but the zero hasn't suddenly lost power yet while testing it, but I have not tested it extensively as after 3 years of having the pi I've yet to turn it into the mobile device that could be considered acceptable. I bought it with the zero, so that means it's not dead after 3 years, though I only use it so often, for a usb fan off and on in case the power is out and for other such off and on sort of things. Like charging the bluetooth headset I have while outside. I got it from amazon and it came with a compass as it is designed to be sturdy and water resistant and for campers/hikers I suppose. The solar part is far too small to possibly charge it realistically, I bet it's 1/8th of an amp, meaning that with a single amp you'd probably be sitting there losing wattage via the transfers, not that I understand electronics all that well, and with such a rhetorical larger 1 amp 5v solar panel it would take 2-4 hours to charge a cellphone or similar device while this would take at least 8 times longer. So rather than 4 hours in direct sunlight you'd have to let it sit 32 hours best case scenario to charge a phone with it. However it acts better than that as it is 16 amp hours, of which means after draining it in one day you'd be required to let it sit in the sun for 512 potentially. Or maybe if it charges in an hour rather than four being the variable then it's still going to take 16*8 and that's 128 hours for every day you used ths hit out of it. Assuming that is that drining from both usb's won't take even more power out of it too quickly in which case 16 is really less than 16 hours but still takes 16 worth of charging itself. So it'd drain faster probably than 16 if both were being used at once and then you'd have to wait 128 approximate hours for it to recharge. Of which is why I have a solar panel that's literally 20 times the surface area of it instead that folds. I'd charge it with that, but at least it looking cool is a thing. *checks* I was wrong, this model is 10 amp hours but I bought a second that was not the same brand that was 6 so I had in my mind sixteen as it's better to have two batteries in case one breaks. I like having such redundancies. " FLOUREON 10,000mAh Solar Power Bank Portable Solar Phone Charger with LED Flashlight Dual 2.1A USB Max Waterproof Portable Cell Phone Power Bank (Green) " but the vendor's link is gone, as happens with amazon. it was three years ago

>>5937 >also forgot to include the baofeng uv-5r's 5v to 10v inverter that halves amps for volts that is powering on the lcd so would not have to solder to pi but instead plug into second usb out of solar battery I wasn't using the ham radio anyway, so.... Anyway, for that it fit miraculously. The lcd is a 12v with 6 watts demanded and this way it's 5 watts at 10v instead. Others said such a thing was not even necessary but perhaps my screen is brighter, of which you can turn down it's luminosity as well as control it's contrast. In fact it is too bright, hence all of that *glare. I should go ahead and buy several usb sound cards if this works as they break so easily they apparently do. Not that anyone cares but I was just wanting a thorough image but failed, as usual.

>>5983 You can install a Linux distro in Win7 through win32-loader, Wubi or UNetBootin. You could also enable USB passthrough for a VM. Can you try the USB sound card on your WIn7 machine? Also reset the CMOS on your BIOS by removing the battery to clear the password. GPIO PWM is the cheapest option, USB sound card is the easiest. You can easily make DIY capacitors from aluminum foil and paper. If you can get a terminal in Raspbian, you should enter the rest of the commands for GPIO PWM audio and try the headphones again.

>>5989 >actually installing it rather than flip flopping as a live usb I don't want to install it as installation go things from the tar is too hard for me and I don't want to rely on networks when I get a new or dead computer. >trying the sound card in win7 Even though it requires no drivers win7 felt compelled to do it anyway and then it scarily requires a restart for something that requires no drivers. Anyway, it works a bit better than in raspbian, the whining noise is less loud and more like a crt tv's static noise, snow, and it's 80 percent that and 20 percent the noise you want to hear, but I have not restarted it yet until after this message. >cmos I was afraid to break my computer when I was researching breaking it's password. The keyboard might stop working and it was not a guarantee to work. Drivers can be reset I read for things such as the keyboard or it's lcd and such. So I never risked it. GPIO PWM requires me to figure out how to tell the Linux OS's what to do, of which hasn't worked out so far as simple lines in the config have never solved an issue for me and opening the terminal sounds just problematic for my non-network uses. Hard to remember what to do when you start sudo-apt getting everything, or whatever else. Making the components I need sounds cool, so long as I have not oxidized another soldering iron tip I could try to do that. I guess it can't break it if you're just trying to get the capacitor to hold enough of a charge to power on the speakers you solder to it. It needs resistors to hold the watts back, then to have them charge in the capacitor, then released again with another resistor that's less powerful than the first? Is that the point? Because I don't have electronics education and just looking at all of those colors on resistors and such makes me confused mathematically. But I get that without something to amplify the speakers they stay with a signal but silent. The terminal is a thing in raspbian that it comes with, linux always has that, but it's a separate OS to the lakka. If I build or get the components for all I know lakka will just output the stuff if I put just the simple line of text into the config. Or maybe ssh should be a thing I get working if it never ever works, of which I will resent as if I am in the woods with not but my phones and the pi zero pda then when it breaks and I have to use the android to burn the OS back on the sd I doubt that the android will be able to control it with the ssh terminal feature, as i would leave a laptop behind. then again another pi should be able to do that I imagine, so once I get the better pi I could use the zero with the very soykafty gpio pin lcd I decided was not worth the effort of soldering, nor could work in lakka and could not work in picore either, so I could use it to turn it into a linux maintenance computer for a pi 4 or 3 that I get. I have two keyboards after all and raspbian should have a driver working for on screen keyboard for the touch pad gpio 3.5'' lcd that's in that box in that image up there. It came with a plastic stylus, so it's that type, hitting the tiny keys would be easier than a very small phone if the keyboard is too small on the screen. I guess if I have to use ssh that will be how I do it as I will not use this zero forever anyway. I only have it due to being destitute and so I'd also not throw it away. But that will be months from now so the idea still depresses me. >>5989 >actually installing it rather than flip flopping as a live usb I don't want to install it as installation go things from the tar is too hard for me and I don't want to rely on networks when I get a new or dead computer. >trying the sound card in win7 Even though it req >cmos I was afraid to break my computer when I was researching breaking it's password.

I can hear it but it's not fun on the raspbian as the noise is abhorrent on that one.

>>5993 >rebooted It worked about the same but after unplugging it the midi's outputted nothing until I restarted the computer a second time. The midi's but not the computers actual audio output. Made me sweat a little. But yeah, once I get refunded for what I've bought I'll buy something else, and or try to make capacitors and resistors myself. While I'm at it it'd be great to make an on/off switch so the thing won't have to be opened to pull the cords so you can plug them in again to power the pi on again. Or I could get some usb with a power switch on it and have a hole at a part of the cigar box where it can be accessed I guess. I'll probably go ahead and add this off and on to my 'cheapest computer image from new parts' though not upload it a third time or I'll start compulsively doing it over and over.

>>5995 Most of the problems from the Pi Zero could be fixed by using a proper Raspberry Pi 2, 3, 4 or even better, an Orange Pi for 10 USD. An Orange Pi 3 has proper 3.5 mm audio output and HDMI, and it will be cheaper than an HDMI splitter. If you can solder the audio output to the GPIO, then the Orange Pi Zero2 will also work for $20. Also get a spare sd card. If you hear noise on the USB sound card output, it is broken. You can install a dualboot Linux installation through win32-loader or Wubi. Strongly recommend finding the motherboard manual for your Win7 computer and resetting the CMOS. Since you have a soldering iron, you can also easily salvage capacitors and resistors from any circuit board. Just go dumpster diving for the first electronic device you can find, and strip the capacitors and resistors from it. Post what you can find, and we can make an equivalent RC filter from it. You need the capacitors and resistors on the PWM GPIO in order to filter out high frequency noise created by the PWM. Do you have access to the LAN in Lakka?

>>6058 >another soc I plan to, I just bought this one first 3 years ago after thinking about getting a pi with zero money to spend years before that and once I got it I never ended up using it of which depressed me. I used to think that having an orange pi would be really cool but read more complaints about it, and knowing I'm problematic with computers more and more I avoided thinking about an orange pi for a long while. They're not as cheap as pi zero's where I see them sold anyway. But a pi 4 or 3 I need to eventually get. Or even some odroid, lakka has them highly ranked in compatibility, the u4 ones if I recall. xu4 my history has in it, so that must be it. Odroid c2 might not work with lakka due to some firmware issue I assume. Surely it is indeed broken. I'd like to eventually rip the cmos out of the computer once I stop feeling so comfortable on old windows computers, or get a second one that is as nice or nicer so as to take the other for granted so as to be able to want to risk the driver issues of removing the cmos. But about partitions, they always seemed difficult when I read about the software people use. It is probably because I never have anything to mess around with that I'm willing to accidentally break so i lack real experience. I had the idea of opening a Tiger that I own in a video game display collection that's soykafty anyway and it of course has at least one resistor, 2.0 ohm, and 3 ceramic capacitors I can't identify, a big blue electroylitic capacitor, and some yellow thing i assume is a capacitor as well and a black transistor. So if i do it mono I could use the resistors of more than one Tiger game console assuming they have not died due to old age, the resistors and capacitors, and then maybe I'll have audio, if I have not oxidized yet another soldering iron tip that is on top of the aging issue. I guess I could just imitate the order that the images I posted shows to the corresponding GPIO pins but won't it be a different thing I type into the config? It's hard to identify these things as I'm some forever-noob with things. Regardless these Tiger 'consoles' actually deserve to be torn apart. I decided to do it rather than wait for them to refund me just so some day another sound card can break. I'd rather have the pi be more repairable than that so with all it's peripherals being so universal it makes sense to solder normal speakers to it. Tiger's even have speakers to be ripped out and used. But to review those images, for mono I need 2 resistors and two capacitors. So I must kill another Tiger and then I'll have them. But the second resistor is meant to be a lesser number, I might need to kill an alarm clock I don't use or something because that's the issue with that so far. They'd be the same resistance. So I really have too many capacitors and not enough resistors. Unless the yellow thing is one, I can't even tell but it looks like what alixpress has listed as 'an audio capcitor', so I think it's five capcitors and only 1 resistor, 1 transistor. Then again I didn't take it entirely apart, maybe on the opposite side of a chip there's more parts? I need to use a watch maker tier screw driver for it. Or a knife I guess. *does it* Tediously wasted my time, but a normal screw driver worked to find zero alternative parts I can use on the other side of the two chips inside of the thing. RIP Batman, I'm not putting you back together again after that. I guess power rangers will get the axe next, but I *checks* same resistor. I note that they used thicker solder than I would have, maybe I'm not that soykafty at it after all. My screen on the other hand flickers off and on. But anyway, I need another device to kill that won't have the same resistor. *sees konami version of Tiger* Aaaah, it has more resistors than the Tiger and has labels on it's chip. How nice. >resistor 100 (seems red, black, black, brown, can barely see >another says 560 next to it and can barely tell it's color either, might be red and green and brown or yellow... >another blue capacitor like Tiger, "10u16E >round ceramic "10pc, 20pc, and 1uc >has other parts but don't know what they are >silver cylinder "XTAL" >copper and black thingy "1N4148" >another one is also 1n4148 And it of course has a speaker to use. So I guess I don't have the ohm it wants, I have one that is 100 and one that is 560, and that really tiny one that is 2.0 ohm. If I am comprehending this at all that is. The U stuff with capacitors I don't know what it wants. UF? I guess it doesn't matter, I only need two, one larger than the other and maybe it will work if the larger is not towards the ground part parallel to the resistor. Put a small ceramic where the smaller resistor is and the largest capacitor(s) towards the output? The larger resistor at the base of the gpio? I assume it just holds the electricty back then it gets charged up into the capacitor at the front, the ground so it won't get over charged, then that will vibrate the speakers? Amplify the signal? But if the resistor is so huge in comparison the capacitor won't it just shock itself? Or if the resistor is resisting too much and the capacitor too small would it not be silent? I have no idea what I am about to do, so I'm going to sit and think about it as a very poor study. But I feel like i have the proper U's and not the proper resistor to back it up. No 270 nor 150 but 100 and 560. And I can't even identify these tiny round ceramic capacitors. What is it's uf if it's pc or uc? One is legible and says 104 at the top of it, then ABC below that, then at the bottom 25v. I take it that is supposed to tell me it's UF? I guess it's 3v to 24v, and the tinkernut doesn't show his work really well, his capacitors are not flat to where you could see with your eyes well what he used. I mean, he lists what they are to be used obviously, but I dropped out of college and became neet for a reason. I can't do things like maths or chemistry, so I'll just use either the largest or smallest ceramic capacitor for the ground and keep it mono via gpio 13, once I decided to do that rather than glance at electronics information pages to see if the information sinks in before I bite that bullet of soldering again. *uses site to calculate* according to some site's calculator 104=.1uf and the ceramic should be .033uf, so the smaller being of less than 3 digits it won't let me use it to guess their's, though smaller is indeed what I need. Another calc site wants me to know what I don't know, so I guess I'll use the smaller for the the ground and the 100 ohm resistor for the ground, the largest capacitor and resistor for the other part. Then I'll wonder >are they broken? >did I solder it right? >is the config.txt not correct? Of which has me thinking I'm going to overeat while watching tv for a while instead of doing it yet while also simultaneously waiting to be refunded, and I'll just keep the Tiger and Konami in my draw with parts bare for the time being. Lakka has bluetooth and wifi capabilities I'm pretty sure, and they seem to connect but I've not 'done' anything with them like an update. I tried samba and never got it working due to the win7 issue. I have more difficulty concentrating but I'd not doubt if the android's I have could access it with how backwards the world has gotten. That I did not attempt. Maybe if the config thing doesn't work the android can alter it using ssh to get the console thing happening.

>>6064 Resetting the CMOS just resets the BIOS to default settings, which clears the BIOS password. It is always safe to do. Partitioning a dualboot is automatic by the Linux installers, which install a GRUB bootloader that allows booting both Win7 and Linux. Those capacitors and resistors will probably work. If you can get their exact capacitance and resistance values, it is really easy to construct an RC Low-Pass filter circuit. With parallel or series combinations of capacitors or resistors, you can substitute any capacitor or resistor. Old electornics with throughhole components will also be the easiest to solder. If your soldering iron get oxidized, sand it down and then tin it. 10u16E = 10 uF, 16 V electrolytic capacitor 10pc = 10 pF ceramic capacitor 20pc = 20 pF ceramic capacitor 1uc = 1 uF ceramic capacitor resistor 100 = 100 Ohm resistor resistor 560 = 560 Ohm resistor 1N4148 = diode XTAL = crystal Strongly recommend using a multimeter to measure voltages and capacitances. But you already have the components needed for mono output. The most important component is the 10 uF capacitor, which you have. Just get another one and some more 100-1000 Ohms resistors and you can construct a stereo circuit. For now, you can use this as a mono output circuit. ground <-> resistor 560 | | 20pc <------- | | GPIO 18 <-> resistor 100 <-> 10u16E <-> mono output Replace the the 560 resistor with another 100 or 200 resistor if you can get it. If you can connect to the LAN using Lakka, then you should also be able to SSH into Lakka.

>>6069 But why would the 560 be where the ground is when the images from tinkernut say to use the larger resistor closer to the gpio that's outputting the signal? Another 100 or 200? So the ground is to have a larger number despite the diagram?

>>6078 The diagram's order was reversed, but it will still work, you can feasibly use any two 100-500 Ohm resistors in the RC filter. Still recommend salvaging as many resistors and capacitors as possible. To get the loudest and best quality output, it will be best to match the total resistance of both resistors to the impedance of the GPIO at 420 Ohms.

>>6081 Because it's through hole desoldering the things was easy enough but so far I think I need four hands to hold the wire, the resistor/capacitor, the pi chip,the solder, the soldering iron, all simultaneously or it won't solder because the wire/capacitor/resistor/chip/solder/soldering iron keep shifting. I tried soldering it piece by piece of course but I truly suck at soldering, hence my angry Salieri up in the thread randomly placed. Also there was civil unrest conveniently timed both next door and in my own apt so I decided to stop. I need to make a mechanical arm or three to hold things in place. Otherwise it'll take days and days for me to get it to be soldered as I can't take my time if I have to worry about sanding the pen if I take too long. It starts changing colors and all, so I stop and re-tin it periodically, of which just makes me shift things on the table. Even if not the stuff moves too easily.

>>6095 I hear no sound as of yet. Is the polarity backwards or is the solder too thick or what?

Me again, the pi zero poster. I tried to get windows to use putty to control the pi zero with ssh but I could not get that to work, as I figured maybe config.txt simply being altered with notepad+ won't cut it. Also the lan scanner I used crashes windows7 32bit that I am still using, and when I decided to give up and try rapsbian it gave me the IP but putty didn't like it for some reason and refused to let me log into it.

I wonder how many years will go by, so far 3, before I have the pi put together as a mobile device. It really does feel impossible to make it into a 'real mobile computer' even after 200+ usd spent on peripherals.

>>6113 1. One terminal of the speaker must connect directly to the ground, the other to the negative terminal of the 10 uF electrolytic cap. In your picture, the speaker is connecting to the positive terminal of the capacitor instead. This creates a high-pass filter instead of low-pass filter. 2. Electrolytic caps have polarity, you MUST connect positive end of the capacitor to the GPIO side, and negative to the speaker. Negative terminal of capacitor is marked with a stripe or symbol on the capacitor casing. 3. In the picture, it doesn't look like either GPIO 13 or GPIO 18 is connected to the circuit. You need to connect either one of them and the ground to have PWM audio output. >>6115 On Raspbian, open a terminal and run this command, check if sshd is even enabled by connecting with ssh on the Zero over loopback. ssh <usernamehere>@127.0.0.1 >>6116 The most you should need to spend is 20 USD for an Orange Pi, don't waste extra money on peripherals trying to get a Zero to work.

>>6126 Thank's I'll try to fix it again later. It's soldered to 18 though, the bad circuit I attempted. Or do you mean the solder is not good enough on the 18? Or maybe my mind is glitching with it's spacial awareness and I did solder the wrong one. I just don't know anymore.

>>6133 You are right, it is connected to GPIO 18, the picture was so blurry around that pin that it looked like the bare wire was a header pin. The first two points are still valid, though.

I've been thinking about doing a Cyberdeck but, I don't just want some raspberry pi built into an akward 2x4. Maybe something useful with a bunch of electronic troubleshooting equitment like a multimeter, an oscilloscope, and even some wire sniffer stuff. Even some ardino gpio pins for whatever. Or a cyber deck portable vr system built like one of those old luggable PCs from the 80s.

im trying to create a security camera with motioneye os but i cant figure out the wiring (power) and housing situation for it. I'm not sure if i should buy a battery pack for my pi or if it wont last long enough and it's more worthwhile to do the difficult job of wiring it it. anyone gone through this?

>>3953 just b urself man Present Day, Present Time! AHAHAHAHAHA!

About the only interesting thing I can think of would be to make a custom car stereo, but I realize it'd be a big undertaking for someone with very little electrical experience. I'd have to step down the car battery's 12v to the 5v that the pi wants, plus figure out a way to let it shut down cleanly when I turn the car off. Or perhaps keep it in a "standby" mode so it starts up faster, but that risks draining the battery. Not to mention, I don't know what the point would be. If I want to play MP3s or internet radio, I can just use my phone. I'd probably benefit from a better equalizer (which my phone lacks) since I have a damaged rear door that rattles from very low frequencies. A decent equalizer could cut that range and keep me from sounding like a jackass. But if that's all I want, I could just buy a stereo.

>>6135 I resoldered it, it did not work, I gave up and rather than try to get the thing working via ssh and the terminal I bought yet another peripheral and predicably the sound card is not detected by lakka and only raspbian. All in all I'm going to be forced to stick to dystopian android devices, and the ones in gaming console shape are over priced so basically phones are the only thing for me with how windows 7 can't use rapsberry pi's nor does alteration of the config.txt work out despite gossip I had initially read about years ago. I would open a terminal in raspbian to test the speaker I attached to the gpio's but it already has sound, so with lakka still being the issue there's no point.

>>6293 >maybe I should give up and kill a larger sd for retropie >the download won't work anyway /double-post

>>6298 triple gripe

>>6299 >>6298 >it could not detect sound nor even comes with emulators I had so much fun downloading this bloatware. Anyway, I finally got a new sound card, it did not work of course, but then it randomly did finally work, and now lakka randomly hates gba files now that the sound works. They used to work, but now, nope. It even freezes the thing attempting it. Gbc, snes, nes, fine, but suddenly hates gba. Also, how do you even control the volume? I hate this.

>is it bios when before did not need them? >is it replacing the gpsp_libretro.so when ssh nor samba works for me? >do I have to choose between using it on a large hdmi monitor/tv and having it actually mobile, but silent and or just forgo gba emulation when even though laggy it was my fav console? I'm going to do research on disabling sat access in cheap android phones after all of this many year long hopes and dreams farce I've ran into of escaping 'normal' devices. Then buy like 5 of them as for 30 usd you can get pi 3 tier androids, I could have just had 5 of them, even if they break once a year that's five years and 150 usd. With a couple 15 usd controllers the price is under what I've spent on the zero of all things, so I don't see how people warrant even being into pi's with all the problems and price tags to deal with. It should not take months to fix audio just so it can end up breaking itself by doing so. /hate

I noticed before that missing layers are for reflex oriented megaman x and mario kart but then not chrono trigger and such, so maybe they took that into mind and I should hate it less. There's a good 50 games I can imagine liking in between those emulators, not that anyone wants lists of such things that I didn't test yet. I don't want to play until it's handheld. I'll upload an image soon, but I have to get the glue right and say goodbye to using that solar power bank outside of the cigar box. Anyway.... it's neat that it finally works, though randomly. I had to do a fresh install to get it to work. The volume is so loud that I don't really need the headphones in my ears also, and that is kind of a plus really. It'd look dumb having no speakers, even though from that distance they are quiet, from the box I might get them to echo a bit louder if I use proper acoustics. People make cigar box guitars after all. Stuff piercingly loud like the first nes games are fun to quietly listen to as it is without an acoustic geometrical trick so long as it is two feet away from my head. It think it will come out as rather cute if I don't totally wreck the cigar box in my slow whittling. I still hated how hard it was to get the sound working though. That was such a pain in the ass and I made it way more complicated than it needed to be. Or, my equipment did. Both really. I think it really needed to have the sound card plugged in to even recognize it. Or it just randomly breaks with the way it is, lakka. Anyway, a post apocalptic tier umpc should not be overly powered anyway. It can argued to be in bad taste if it were, so I will probably, once having played it, grow to like it, especially if I ever get the two os's on one sd working properly, that was another issue. Probably should not blog in this thread so often, but... /content

>>6304 This! I've experimented with it on a Pi3 but am excited to put it on my 4. Like >>6305 I thought the software was still a few months off of being stable. How has your experience been?

>>6293 To enable GPIO audio after soldering the headphones and components, you also have to run all of the terminal commands in the guide https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero/pi-zero-pwm-audio. Using GPIO pins and electronic components requires a lot of planning and testing, it is not plug-and-play like USB. >>6307 Lakka is fairly unstable with setting default sound outputs because of using pulseaudio. You may have to manually configure the Audio Output each time you boot. Next time when you lose audio, check the Lakka options to see if the Audio Output is set to USB.

I've been thinking about installing the Mycroft voice assistant on one and wiring it's audio up to a talking skull/voice changer Halloween prop (maybe put some goggles on it, mohawk made from 6 inch screws, etc. Or maybe do it up like a WH40K servo skull. Only thing holding me back is that I don't think there is currently a way to do the voice to text side without having every command sent to Mozilla's servers.

>>6336 I could never get putty to work so I can't use ssh and without ssh you can't use the console to use commands. And the controls for audio are not intuitive or I'd know where that setting is. It probably isn't even there as lakka breaks so easy. >>6058 About orange pi zero's, I don't think lakka even supports them so if I don't get backup android devices only I might get a raspberry pi 3b+ as I think that is the wisest choice. [probably stop reading here] I mean really, on amazon (my only choice) orange pi 3s are about 80 usd, a retroid pocket original is 85 currently. Why would I even touch that? Orange's zero probably doesn't work, so.... and yeah, back on raspberry's, how do I know if b+ even works when the normal pi 3 b might be what's more compatible with the lakka, I just can't decide and lakka and similar sites tend to even have 404 pages randomly when searching about nightly to put me off the mood to investigate further. That and my soykafty equipment of course takes the motivation away as I'll not be able to fix it if it doesn't work. ADD and mal-raised brain too of course. *checks by clicking pi 3* It says 2/3, so I guess pi 2 all the way up to 3b+ works? Am I to assume that? oh well for now because 3 different androids, sd cards, a backup gaming controller, those are in my cart awaiting my b-day. I'd like to replace one of those androids with a new system on a chip computer to use with lakka but to begin with I can't dual-boot anyway even if it works with lakka it won't dual boot with a book reading os so it's kinda pointless to even get. I might get a soykafty linux device and mp4 for reading ebooks some day instead but they don't do n64 emulation so all things considered the androids are a better choice and I can't convince myself otherwise after all of this trouble. Those soykafty linux devices, those weird ones, they probably can't even do gba properly anyway, I have no reason to trust that either. Also mp4's probably have no bookmark nor search feature in txt so why do that. So androids it is. Unless I really can convince myself that I can make a computer of my own that's worth a soykaf because I really doubt it. What software will let raspbian and lakka nightly boot up? Will lakka boot up normally in pi 3 using noobs? Will the vendor send me money back if it fails to work out? I know it'd be novel if nothing else to have a custom pc, but really it's not even funny when you're destitute due to being neet while surrounded by family discord and soykaf equipment. The cigar box won't fit in my current go-bag either. That's bothering me right now as I consider the pi 3. I'd be proud of myself to add retroarch on top of raspbian but I know I won't do that. That'd make it a 'proper' computer, if it works like I figure it should and not all slow or something. I've never hardly ever had good luck with using the console even when I do have access to it. It makes me depressed and feel anxiety even starting to use it at this point in life due to past failures. My Internet is too slow to search around anyway. The only reason I'll possibly get a new soc is due to the other peripherals for it I've bought an no other reason and my being bitter that the zero cannot even (despite claims) do gba from what I got working, much less of course do something like n64, obviously it can't, but some pocketgo is 30ish usd, even price gouged 60 usd, I should have done that and it'd have not been a giant autismal cigar box and would have probably had a txt reader in it while using emulators simultaneously of which the thing I have now can't as noobs failed due to needing to use nightly lakka. But yeah, with a 3 b+, IF that works, with that it should work with gba and even some n64 games. That'd be neat. Some are only 38 usd, but I might need heat syncs and a wire too, so it's really 40+. Not very expensive. One android i am considering is 55 usd so I could swap that and hope it works out this time without taking 3 years to be in a position to be a mobile device. I'm not sure which version of nightly is even to be chosen for pi 3. I don't recall how I choose it for the pi zero and i get too burned out obviously. The slow Internet does not help of course. >and yet another blog was sent

>>6365 The commands should be entered in Raspbian's terminal first to test the GPIO audio setup, since it doesn't need SSH. For Lakka, if you can't get PuTTY to work, use a VM to boot Devuan on your computer and use SSH from it. Lakka supports Orange Pi, but for your use case of GBA and SNES emulation, get a Raspberry Pi 3 for 40 USD. It can even emulate N64 and PSX. Also download the images using a wired LAN connection or torrent, or use a downloader with download resuming like JDownloader. https://jdownloader.org/download/index

I'm trying to find a gift for someone who has once mentioned that he wanted an Arduino or a Raspberry Pi. I don't know anything about programation, but I know that he works on debuggers, compilers and 3d engines usually. What type of project could he be interested in and what should I get him ?

>>5936 I've been thinking of making a tiny PDA thing as well. It would be pretty deprived of peripherals though. A USB-C for sure, maybe but probably not a really small bluetooth antenna, and audio jack if im feeling daring The thing would be split up in two parts; the battery, with a Tiny 2040 (usb c included) & most of the keyboard and screen (an oled, they're good res for their size) , and a sort of extension part that plugs into the USB when it's not charging the battery, which would have the peripherals for a microSD card reader since the 2040 only has 8mb of memory, and the other part lf the keyboard. The kyb would be a four-row qwerty-backspace-enter split evenly between part C and D When part D isn't available, the keyboard would rely heavily on control keys ; the 2nd row would allow for caps lock and for row 1 to switch between next and previous row (ENTER/BACKSPACE/SHIFT included.) I don't know if its physically viable but it sounds better than cramming it all in on part C I don't know how the power usage would go on something like that or what battery I should use. I've been thinking of just testing with one button cell and stacking until it reaches something relatively usable like 4 hours. Dunno about the software, I'm thinking about making my own but I clearly lack the knowledge. It's more of a question for /λ/ anyways 2040s are currently out of stock on the seller's page so I'm stagnating right now. If any lainon knows where I can start I'll be grateful for your assistance.

Wanting to hook up a tamagotchi's lcd output to my computer so I can have it as a desktop pet. Is it possible to do something like this with an arduino or pi? Wouldn't need a super high output speed but not sure if either could read in lcd data fast enough.

.onion web server, IRC server. Soon, hosting an Element.io server,... replacing matrix.org accounts of me and my friends. Raspberry Pi 4 Model B 8GB “workstation” (I have a MacBokk Air (2020, M1) w/ 16GB RAM) and i have been turning into an arm nerd. Plan on getting a PineBook Pro, and a Beagle Board RISC-V when it comes out. IWith 8GB RAM and ZRAM it’s an “okay” desktop. I can’t wait to see what the Pi 5 can do.

>>4602 is this one of those usb scissor switch keyboards that actually use laptop keyboard? they look good and also have touchpad. interesting to see what the keyboard driver board looks like.

>>4318 Pretty much this. In Germany people go just 20% below new for their used soykaf. It's insane. Seen it too often that they actually sell above market price for their used soykaf, because they bought it for even higher back in the day. (Speaking of film and photography gear, but it is pretty universal)

>>4008 can you provide more information on how to do that

i am building a 2d accelerometer computer for my truck with a lil memsic 2125

Presently working on a easy way to record some moderate-level audio (mp3 qual?) For long periods of time (8-24 hrs), with multiple transmitters for the audio and a single reciever for the audio While cheap arduinos are less power hungry and more than capable, will I need a full RPi 4 or W as reciever? I wanna record lots of drains/waterways for that lovely bubbly sound of water running over rocks, garbage, and small drops. Take pics of entrance or in (depending on access) and place em, place the reciever well hidden, move on, recover at the end of the day

>>6740 And some people I have told the concept to, even prefacing it with 'Making an album' seem to call it bugging and asking me (sarcastically) if Im a cop or a thief. I am neither,but from a tech point of view, yes, I am 'bugging' waterways. Tell me how to build bugs with some sensitivity and range, lains

>>6740 Personally I would just get a budget dictaphone, or just whatever one you can find used online for pocket change. Cheaper in both time and at-purchase cost. They often have recording battery times of upwards 20h. Also less suspicious, if somebody finds some weird techno gizmo laying about they might find it weird, a dictaphone is very recognizeable as an audio device and you can just put a note on the side-down side saying "recording the water noises for a project, please dont steal me".

>>6604 You'd probably be better off with a tamagotchi emulator running on your computer. For hardware, you'd have to tap into the video cable to the LCD, which probably has at least a dozen wires. Maybe you could backdoor into the CPU and dump a video RAM buffer and send that to your pc. There is tons of information on the internet of people hacking tamagotchis. You can start by searching hackaday for tamagotchi, and make sure to check out the tamagotchi singularity.

>>3474 I use mine to seed torrents on I2P.

So far this is the tiniest and cheapest board with Ethernet and wifi to run Linux on. It's very old however and is really hard to buy. Does anyone know newer similar devices under 15 US dollars?

>>6058 Lakka had a server problem and never fixed it so now I'm thinking I might indeed go the orange zero route. Their old distros worked better and are gone. Orange pi does have a retrorangepi distro project.I hate how adding things with linux takes a network. I will have 200 usd so I have atomic pi, pi 3b+, orange pi zero, and peripherals that will work on them al with what I also already have to go with them in my cart for christmas. Rather than load lakka on the atom I might install mupen and mednafen. As it is all three do lubuntu of which is my fav linux. Having three I cannot go wrong. I wil end up liking at least one of them and will give the winner a cedar frame that I will glue and screw and drill together. My cigar box I killed horribly. I like sticking to my fav distros but honestly just adding mednafen and mupen to lubuntu is more sane....though an os immediately working independently of another pleases me it's unrealistic. I kinda doubt emulators would work well on lubuntu arm especially with my eternal noob skills though but atom ought to be safer I figure. Also my composite cord unsoldered from the zero I ignore. I really suck at soldering... I hope it works out this time so I can post images of it. Of my peripherals are an hdmi to vga and a vga to composite so that they all can use the cheapest and most retro monitor potentially as well as cords to make them all use the same usb power banks back and forth. Redundant but efficient that way. >so that's my blog for today.... In the meantime I'm just downloading distros in fear that they will go away...while pondering what I really want as a book reader and cheap chinese emulator handheld would be the easiest to keep me happy but also too consumer tier and indeed non-repairable. If I spiral I'll end up with that and hate myself. >_< What makes me want orange, I like the speed ocarina of fps shows for orange zero on youtube.I am sure bosses will suffer and ganon won't be beatable though. It being that cheap and being leagues better than the raspi0 is neat though to the point I want one after thinking over it al and seeing that it has it's own distro for 'it'. I wonder if it was overclocked.

>>6365 (me) >back when making this post was not told about retrorangepi (libretro core frontend linux distro thingy like retroarch or lakka or emuelec or etc) The neet may yet get an orange pi zero once this neet gets money on x-mas provided that his priorities do not shift to other things. On amazon, my gift cards are that, both are overpriced, pi 3b+ and orange pi zero's. The orange zero actually is half shipping it's price is but the pi's are like 55+ when they used to be 35 while zero is 22ish+ while having 10 in hidden shipping and 11 in actually seen, so either way I'm gypped. I have os's for both options as I kinda want both but also want a new opendingux console...and a bicycle as I can barely walk now days due to plantar fasciitis (lost 40 lbs since last posted in the thread though it did not help) but don't like having hypertension from being too on my ass. Such horrible genes gave me this obvious adhd 'you' see in this thread. I think that if I get enough polymer clay I might be able to make a clunky 'solid piece' of an umpc but only get 200 usd, so with just two items, the zero at 40+ and the bastard of a gcw-zero/gp2x I want at 100+, the heatsink for 3, the av cord, new sd's, it comes out with just what I need at near 200 so there's no room for polymer clay to be bought. The zero would come with a case and an expansion board so it's not that bad for 40ish usd I guess though without the heat sink of which are way overpriced and often have a hidden fee themselves it'd melt even if I did forgo the expansion board and solder the composite again as I did with pi zero. But yeah, with 200 in gift money I should have enough for the pi zero lts to be workin fine with all the peripherals I have already using lubuntu (maybe) and retrorangepi for it and maybe even android (probably not unless lubuntu is too hard to install the gui for as I'm an eternal baka) and also get an opendingux console for book reading and gaming to go with it. And hopefully no spiraling to getting a book reader and opendingux console only with no new 'pi' to try to make into a custom computer worth having. If it does not work out I can't send it back due to shipping fees though it is cheaper than pi 3b+ now days...so stressful. I've been way too annoying in this thread of which is also stressful, the meandering blogs so I guess I'll sage. It'll be super cool if the lcd works with the orange pi zero lts though as I expect the sound card to work but still are nervous about the lcd's resolution as no one ever is specific enough about specifications nor requirements now days of software. It's made for composite out and can use an old crt I gather but then again I'm so retardedly inefficient I don't even know anymore.

>>7366 (me) >got wood, felt, paint, hot glue gun, drill, hack saw, etc for frame to go with peripherals and pi >bought raspberry pi 3a, finally, with heatsinks and such >splitter isn't normal usb but micro that the pi zero used....forgot about that >got the wrong 3.5'' to rca composite out cords of which all look alike Well... as a neet with not even a union bank account I'll be selling something on craigslist now I guess to get the other cord...also another splitter as they cost about as much as the adapter anyway to fix 'that'. So far the bot hasn't put my ad up to sell anything, but that's neither here nor there really to the thread. I can't wait to try raspup, lubuntu, and lakka on it to see if it agrees with the composite video out method. I know raspup has no issue with it but have worries about Lakka with their old 2.x version nightly distros now gone. Also I suck at sawing, really badly. It's not even funny. The dollar 'store' wood does not help. I also have an old 3.5'' gpio fake waveshare touchscreen lcd but doubt I could get Lakka to work with it due to the whole driver issue. I could possibly put raspbian or whatever on it then just merely add mednafen and mupen64+ (or try to, Linux is so hard). I could end up using the gpio lcd one I bought a long time ago and never used due to sucking at soldering to the point that the pi zero never got to the point of being able to use it. This pi 3a+ has them already there though of course... I just want it to be able to read books and play the old video games obviously. Ideally I'd not flip flop OS's. Also Pinn looks hard to use. It's too bad ventoy only just now became a thing. Newer Lakka for x86 pretty sure claims to have ventoy support, that's a neat concept, just pasting in the iso/img files and still using it as a thumb drive on top of it. There's noobs but I know from experience that it's not going to likely work.

>>6839 >>6906 not under the price you are saying but depends on how much power you want >could use the old pi 0w if need less powerful cpu/gpu >the hat has POE if ya need it (MakerFocus Raspberry Pi Expansion Board Ethernet/USB HUB HAT) >and support/resources will be all over the place because it is a pi (10$ or 15$) +15 ish for the hat so 30$ all together inb4: if 30 $ just get a Pi 3 or 3+ well op showed a image of a stick the size of gum so ya

>>7562 >got pi 3 finally >dual boot not working with composite out >try to install retroarch on top of raspbian >>Error creating SDL window! >>Could not initialize OpenGL / GLES library >>Renderer failed to initialize! >>Window failed to initialize! ...years of planning so far...not paying off... I'm too upset to continue. I also set fire to my food as my stove malfunctioned tonight, again. The parents are complaining gratuitously for hours over it. I just wanted a daily driver. I read SD switchers need to be unplugged so they're pointless, is that true? Is anyone out there? I wish I had someone to personally help me but I already tried my best over these past 3 years.

also there's a squiggle down the screen for some reason despite having the proper cord and despite having a 3amp battery bank it still gives me the low volt warning. :( I hate coping with androids but they are cheap and work. I regret having wasted 200+ usd so far. I regret this a lot as a neet. I wish someone would have warned me, but I can't engineer something that can switch sd cards nor get something like noobs to work.

Then again it's fixed. Now to wait for the working usb splitter so I can actually make something with sound and such.

>decided to finally get ssh working for the first time >failed at it >Winscp doesn't work either I honestly would sell all of my pi stuff if I could but have no bank account to speak of so ebay is a no-go. I'm neet of course. I have buyer's remorse the more I mess with it and never learn anything, not networking, soldering, machine language nor coding, I just get frustrated and unseen problems from the setup and as previously mentioned on this site I've spent 200+ on it so far despite them being though of as cheap devices. With the windows they have being off screen and the many other issues I've faced I've learned to hate raspberry pi's more and more despite having to wait years to get one/them. Nothing ever 'clicks' with me. I've tried to learn things before but I can't cope with how Linux works, it's package management, command line interfaces, it's been years of off and on trying and tutorials only making it seem harder to me rather than easier. Today I had to nuke my pi's OS that I installed Retropie on top of, Raspbian, as I goofed the resolution so it had a black screen. I went into config and it didn't listen to my inputs and there was no obvious place to look for to find what the default was. I figure the config just never does anything. It never did before when directly accessed. I don't trust direct access as I've never had success before, barring access of some pocketgo's firmware I never did have success. I wish they taught people such things in school rather than forgetful math and half baked English as well and mild history of your nation. I doubt I'll get much at a pawn shop or craigslist but I'm just about done. Nothing ever works out. It even blacked out on me once today despite my '3amp' battery bank that's highly rated that I just bought with the pi 3a+.

>>7627 >I wish they taught people such things in school rather than forgetful math and half baked English as well and mild history of your nation. If you couldn't pick that up, you wouldn't have been able to pick this up even if they did. Cut your losses and... Well, go apply to work as a doorman at Walmart.

>>7628 To get a job at walmart you'd need a work history actually. Let's not start up with that. Also, picking it up, they didn't give any computer courses other than learning microsoft applications such as Word or Excel. That does not count. Unless you meant English or Math, they grade on a curve with the bad maths and with English it's the USA so yeah.

>>7628 >comment too long For the record it didn't install, Winscp, and the guides with command line never are what you are seeing exactly.

>>>>7628 >neurosuggesting that learning pointless things equates to your ability to learn things that do have a point You never heard people back then say 'this is pointless'? Your sentiment is asinine. Sorry to post three times but I have time to waste now that I realize that all I can do is wait as usual for x thing to happen, such as the new usb splitter in the mail to see if the voltage can handle it. There's not many places to talk about it as plenty of places have your type there, bitter towards my type and they expect me to get on their level when they were rasied completely differently. I grew up without a computer while wishing I had one. That's the key difference. Old dogs and new tricks. My first computer was in 2007 when I was 18 and it was a win9x. I promptly learned to use emulators and drivers (or a driver really, that and directx if I recall) on it but stayed at that level this entire time. They taught me MS word in HS and Excel. It's not my fault that school was designed by retards for retards, the strange math teachers that don't know how to talk to normal people aside. Are you a math teacher? If you are, you should know that they are never people persons. The sentiment is false about learning pointless x thing to prove you can learn something more of value. It labors under the assumption that my mind can't bullshit detect.

>>6126 An orange pi zero lts is 44ish usd when including the hidden fees. I'm just saying. >wish ssh worked out but didn't with that pi zero as it actually was hiding the option due to a glitch and the non-glitched lakka had no composite out I tried ssh today again, as previously vented about, but I don't understand how I'm supposed to know what directory is what despite the commands to list them. I'm too adhd to see it without a gui and of course the config text does literally nothing. It shows changes you make without going into it but I think these things were designed to disallow access from the outside or something. I got putty and the ip and such to log into it but didn't do the last step as I don't see the directories in my head like others do in between systems. I'm 99 percent there but still failed at it though they were connected and the password was used and the pi name and all. I get what to do but still can't do it for some reason. Also the pi 3a+ I ended up buying was about 40 and usually they are 50+ on amazon. A pi zero can go for 75 usd now days. It's so stressful. Anyway, I almost got the file tunnel thing to work but aren't getting it. The paths aren't named what I'd expect them to be named for some reason.

>>3483 I suck at soldering so never got to use it myself much. It kept coming undone, anything I soldered.

>the portable version works of winscp Why even have non-portable stuff for windows I wonder? I guess I'll have to try again later. Rare errors indeed. That's my whole life.

>>7637 >transfer stalls after only three small files transferred over out of 600+ Wow. Utter failure as usual. So the next issue is.... my router being incompatible? What? Is it the voltage being low making the pi pause for 15 seconds? I kept trying again and it only got three books in. I mean technically it worked, but of 600+ in three tries? Then there's the fact that my roms are the big ones not the book folder files. Pathetic.

>>7638 Read The Linux Command Line if you can't even figure out the file hierarchy from the command line

>>7639 Reading won't help. I need to succeed in practice. I read about the tree metaphor a decade or more ago so it's not like reading a book on it when the directories are never the exact same will help me visualize. It could be akin to aphantasia rather than just not being mathematical. I can clearly see directories with a gui but it changes how it's written it seems with the command line. It won't work anyway. WinSCP proved that to me that my networked computers are incompatible with one another and or their router. I need to buy more equipment or just give up and I'm neet so generally I give up. It needs a new battery and a usb splitter to transfer files and also a larger screen and for that monitor it's own dedicated battery. I need to spend 50 plus hidden fees for the monitor, 20 plus hidden fees for the battery, and have a dongle already in the mail that was rated highly and was said to work with the pi's. I have 10ish usd on the amazon account and 15 usd in cash from selling things on craigslist and will make 200 usd most likely in b-day money more than half a year from now.... so I just sit here. Don't get me wrong, I'd like to learn it but I can't if I've learned helplessness and a bad setup that's stopping a light from being at the end of my tunnel, no pun intended.

>>7638 Have you tried using rate limiting to avoid creating an overload?

>>7648 No, but I'm not sure if that'd stop the pi from pausing for 15+ seconds thus creating the timeout. I think that perhaps the low voltage makes it slow down though I'm an eternal noob. I'll probably try to put the files in directly using Puppy Linux on a thrift store PC of mine. Hopefully it will work out (for once). Or I'll wait for the usb splitter but with that low voltage warning I'm thinking it's better to get to learning ssh and such too hence my failures of late. I've reading to do and to try to memorize before I try anything in regards to the command line also so I'm waiting right now and trying to get organized (have non-24 and other issues). But thank you for the idea.

>>7648 TCP includes mechanisms to deal with that and SCP works over TCP, so that shouldn't be the problem. OP, why are you undervolting your Pi?

I want to make a ghetto RTK base-station. I have a cheap ublox neo-M8N module with the old 2.0.1 firmware that still accepts hex commands meant for the expensive neo-M8T variants, allowing it to output data required for RTK. It doesnt have onboard memory so i have to send the commands every time it powers on. Ublox have since patched it for newer firmware for no other reason than to piss off people like me. I got a chinese gnss antenna and soldered it to this shoe polish can. Professional gnss antennas all have a large circular ground plane to eliminate signals bouncing back from below along with the usual "grouind related RF stuff i dont know about. Its not great and i don't fully understand what im doing but its all i got. My country has a public rtk network meant for construction/agricultural companies and their engineers, its horribly documented and cryptic especially to a retarded high school dropout like me but ill figure it out, im halfway there. Theres an open source program called RTKLIB for doing rtk stuff, i hope itll run well on my orange pi one. I hope to be able to feed it data from our public rtk network plus my soykaf base-station so it can compute a "solution" and output said solution as RTCM messages i can send to the rover, a second ublox M8N module that it should accept them and know what to do with them. So now i just need to figure out how to use rtklib properly, how to automatically send hex commands through the raspberry pi's uart, and then i just need for find a reliable way to send the rtcm messages to the rover's uart. I have some hc-12 modules but theyre not exactly reliable, thats a problem for later. Also i know that im using soykafty sub-par components and that i dont know know wtf im doing and that even if i get all of the above working perfectly, which i wont, i will probably not see any improvement in accuracy and may actually make it worse and that this is almost certainly a waste of time. I know that. Im painfully aware of that. So there, thats my project.

>>7654 I'm not the actual OP of the thread nor that poster suggesting what to try but I am a neet that bought a battery bank to try to make it into a mobile setup/device and other cheap peripherals but they lied about it being 3amps. It's 2.4 pretty sure so that's why. I don't have money yet to replace it as I make only at most 400 usd per year approx. Some items have priority over the pi project or it'd have turned out better. Most battery banks are not 3amps, they're 1amp, 2amp, and 2.4 or 2.5. I actually have collected so far 4 of them but none can power it well enough. Because I have a soldering iron, though I'm terrible with it due to having no flux and other issues, perhaps I can learn electronics and use broken electronics to make two usb's combine their amps without over volting the thing but I'm too baka to try it. 10v at 3amps is possible if I were to destroy two of my usb cords so technically if it's designed to not overdraw from the two then maybe it would work. It might be that simple though I am terrible with the iron and keep oxidizing it. If the usb splitter, the flash drive, the game controller or keyboard, the sound card, and the lcd make a power outage I will try that as I'll probably make no money to get another 5th bank and logically I"m not sure if there's a reason to if these things are designed to power out both usb ports at once. I have two usb voltage/amp meter devices so I'll test the ability of the banks before I decide to do that but I'm still waiting for the splitter so there's no reason really.

>finally got the usb splitter >everything is working fine despite the overbearing warning Why the HELL does it even keep warning me when only one was plugged in when all four, including the monitor, is working with blasting sound?

sudo nano /boot/config.txt # Disable under-voltage warning avoid_warnings=1 *reboots it* >still shows the annoying message grrrrRRRRRRR

>>7661 (me) I added a line break there though unlike the code shows....

>>7661 >>7661 or rather a space to where it's underneath it, the "avoid etc" part.

># Disable under-voltage warning Got rid of that part and used control plus o then y and enter and it's fixed now; however it bullied me when typing startx upon rebooting with sudo reboot by interrupting me with the error message about the low volt the first time i rebooted. I'm happier now having finally got the config text to be controlled by me through console. That's real progress I'd say. >it came back in the GUI as I typed this What the fuarrrk

>tried again >put # etc back >same result, only lightning icon hidden of which wasn't what was annoying, the giant text box is.... Why oh why is there not a guide for this for fixing Raspbian?

>>7665 Tried sudo nano /boot/cmdline.txt loglevel=1 at the end of it's line as well and it is still showing it despite what the official forums say to do, unless I'm goofing that... The dialog box is STILL there. Icon is gone that I could ignore ironically. I wish something would go actually right in my life for once.

>>7666 (me (again)) >tries to get sound to work on mednafen with newest raspbian >not working no matter what unless through rca and not usb though usb works for rasbpian itself of course >maybe the older will work better as it won't have the message plastered over mednafen? >use 2018 stretch >sound card working in mednafen! >literally 10x slower though, even gb unplayable due to running extremely laggy These fuarrrking things. All of them are bad in one way or another I suspect. My Internet and lack of funding means slow downloads and cringing when I reflash so I'm giving up again for today and next I'll try 2020 and 2019 I guess to see if I can hide the message while also having sound work through the usb (as it did once in lakka on the zero (of which was also a pain of course to get working and only nightly worked for composite out with that)). I mean, nothing but issues. There's not a single OS working right for the things. Raspup can't connect to the Internet hardly, Raspbian has regression issues apparently, Lakka hates composite unless it's some now deleted nightly version, dual booting never works easily either even if two os's did work together well, such a soykafshow. I made a mistake. I should have gotten the orange pi zero lts. It could not have gone any worse really. Really everything is soykaf. I bought a retroid pocket and it could not mount a drive. Bought a card-android too that could not mount a drive once. Sent both back. The pocketgo v1 I have plays so well unless randomly Golden Sun 2 or Legacy of Goku won't run. I could go blow 100ish on a better opendginux, they read books and might play gba and psx but no n64 at all as it's in alpha. So that's leaving androids but the retroid pocket failed me and cheaper androids bully you over not having a sim card with a busy signal and other dystopian things about them like tracking and uninstallable software and overly wide screens and touch screens, them being hard to hold notwithstanding for gaming. A pi would be reparable, that's of the largest appeal, but I cna't even get it working to begin with. Solder coming undone, sound issues, power management issues being overbearing on top of other windows, sloooow emulation on dated OS, it's all so tiring. How am I supposed to avoid spending money on booze and drugs if I can't even get into a hobby like this one? I can smell the iodine already when I end up on dialysis in my early 40s from hypertension if I keep spiraling. Now that I don't overeat and try to sleep at the same time every day (can't do it, non-24 is inevitable with me) and don't drink booze I'm actually having homicidal urges and randomly crying for no reason because nothing ever goes according to plan. Not just this pi thing I've been hoping to go well for literally years. Too much tension due to being poor. These things were meant to be cheap and easily set up. There's nowhere but here to vent about it either of course. I've not loaded retropie up lately as it's going to make me mad with tiny font from what I recall. I don't even know if it'd hate the usb sound card too though it's perfectly fine for Internet browsing. What's that make this pi I have? A chrome browser? A chromebook? Except they can run android apk's I hear (unless they don't, I don't know). So I guess the simple thing to do is *pause for effect* get a giant battery and a giant tv so the sound will work and then another giant battery for the pi itself so it won't bitch me the fuarrrk out over that new dialog. So I need to spend another 100-200 usd I guess on that. 300 usd non-mobile pc that will be as powerful as a 35 usd android. I can't wait until like half a year from now once I have the money for that. Woopie. >just get a better pi they said >don't even buy new peripherals they said I'll probably not pawn it but I might spend the 15 usd I've saved up from craigslist sells on a gallon of high gravity beer this week at some point if I keep having a bad day every single day for days straight. Honestly if I could get the money back though I would as I totally have buyer's remorse for it's price for it to not work well this way no matter what I try over these past three years.

>>7668 (me) Right click the taskbar to remove the battery plugin. This gets rid of the overbearing undervoltage warnings. So that's one issue solved.

>>7672 >later >no confidence to dual boot >installed retropie on raspbian >works fine (though ran into issues with ssh and samba working and had to paste things in using a thumb drive using raspbian itself) >everything seemingly fine >n64 either crashes immediately or stays in super small screen >refuses to listen to resolution changes >it's probably because I didn't use retropie separately despite what people would have you believe >slow is one thing but less than 1/4 of the 3.5'' screen.... >on crt it's almost big enough but cit off a bit on the lower left hand, of which is where the thing scales to Busy sawing wood again. I only have a drill but did get cheap saw discs and bit to lock it in place, or screw it/them in place, the discs, for the drill. Slow going. Eventually it'll all be in one piece. Also I successfully cloned my sd so now I have two sd's and also on an external hdd and my new win10 (for dolphin and project64 emulation honestly) a backup file for reinstalling the setup I have of retropie/raspbian with roms and books and transmission and such on it. It's reads as 32 gb big if I recall but some of that is free space. Of the 32 I had 5 or so gb free. Once it's in 'one piece' I hope it's low voltage issue doesn't burn it out too often. It'll be cool to have a custom mobile pc, not so ultra mobile, but still. It'll be probably ten inches tall or so. It being a sort of TAM frame/design will be good for it being so clunky you have to set it down but with the screen higher up you get better posture that way if you see. In a low chair and with a table. If I goof the wood again and again I'll just have to get better tools some day. ...sigh, such a neet life. I need a pi4 I guess and or a larger screen. If i buy a 50-70 usd monitor and battery for it (and inverter cord for the monitor) then 100ish for the pi4 may as well be a thing too. There's always next year...(they gave me the x-mas money early to *laugh* avoid price gouging or I'd not even have had this pi 3a+).

Anyone know the power consumption of the pi 2b? I have a 2b and 4b. >>4071 Pretty sure it doesn't need a fan. It might need a heatsink however. Besides, cheap cases with fans are pretty easy to find. Getting the Pi 4 itself is the hard part. >>4080 I was surprised when I learned this, but then again, it's Broadcom so expect unpleasant surprises.

I use mine as an I2P server so I don't have to run my main computer overnight

>>3705 Maps.me has less options, but you can just download really good maps for free. You'll need something like AOSP or lineageOS+Pico.

But I have an hdmi splitter in the mail so I guess that will have to be my 'diy' solution. Buying yet another peripherals. I would have bought all of those electronic parts, resistors and all, but forgetting the fact that I suck at soldering they end up costing more than the hdmi splitter and you still have to alter how the OS thinks so it will output to it and I have not much confidence with that either. I would have not went on about it but I was out of money and I'm thinking it will switch to hdmi monitor and ignore composite altogether if I plug an hdmi audio and video splitter into it. When I plug hdmi into it and composite it ignores composite. So if that happens my next issues will be what to put into the config to get it to stop that. Or, I'll have to buy a third screen for it. GPIO one was silly due to drivers, composite sound issues, then an hdmi one, the most expensive and large. One is only 5 inches though and is less than 40 usd right now, but I can't buy it without sending stuff back or else I'll get soykaf from my 'father' over it as I'm neet.

>>5099 Public service announcement: don't disassemble and mess around with power supplies or other high voltage components if you don't even know how ground works. Don't have such components operational without a Faraday cage or other insulating enclosure. People get fried relatively often when tinkering around with their microwave.

>>3474 I'm currently working on making a slowmotion camera using an rpi, using this fantastic guide here: https://blog.robertelder.org/recording-660-fps-on-raspberry-pi-camera/ Some of the most important things not mentioned there is the --gain argument to raspiraw to set the analog gain (with values of 0, 128, 192 and 224 translating into a 1x, 2x, 4x and 8x gain respectively) as well as the -k argument in dcraw to set the black level and -r to set white balance. Makes a huge difference for making the result look good. Also I've altered the script such that only raspiraw writes to /dev/shm and everything else writes to disk, otherwise you run out of memory after a little more than a second. But beyond that, it works rather well.

Is Raspberry Pi for Python project or you can use other languages for Raspberry Pie?

>>12897 Anything that runs on ARM can run on a RPi. What made you think it was only python?

>>12898 Have mostly seen Python projects in Raspberry Pi so I asked.

Ihave a pi 3 some code and a led strip running the lights for my grow op works pretty gud

https://github.com/E-H-Q/sonar Hooked a sonar sensor to an arduino with and LCD; planning on attatching it to my car's rear bumper with a cord to the dash board where the LCD is, showing me how much distance I have to back up. It is a work in progress, and I tried to get it working with a teensy 2.0, but I think I soldered wrong and fried the teensy :'(

>>7655 ublox m8n can't be used for RTK basestation since it doesn't output the phase/baseband information. You need something like zed-f9p

would have asked in /sec/ but all the kinda related threads in there are gay. i'm pretty fascinated by SBCs right now as i'm running an energy efficient server with it. i was considering buying a few zeros, and wondering if there were any physical world applications for it, as i saw a headline saying that criminals have used pis for their activities. seems kinda fun

Has anyone looked into building an mp3 player? It's a project I'm considering
