Off-grid computing

This is a thread about designing a personal computing paradigm with no connection to the electrical grid or the ISP grid. Let's see how many use cases can be covered: communications, research, entertainment, media creation, publishing, programming, forms of internet access, etc. Bonus points: - Setups that are cheap. - Setups that are portable (can be moved around in a backpack). - Maximizing open source software and hardware. - Serviceability - fix it yourself. - Minimizing the need to go back to the city to buy stuff, recharge batteries, etc. Leading questions: - Can you design a bug-out bag that would secure your computing needs on the go? - ... what about a long-term power outage? - ... what about a long-term ISP outage? inb4 "we'd have more important things to take care of because it would be a Mad Max society". This thread is about this specific aspect, but it can be expanded to include ways to defend such a setup from theft and such.

Here's a design in process. **tl;dr: raspberry pi 400 + solar charger, FOSS'd smartphone, solar piratebox.** Using solar panels to get the voltage you'd get from a wall socket requires a big setup: big panels with a big battery and one or two more devices. An alternative is using a raspberry pi, which can be charged with the same voltage a smartphone needs. My bet would be a raspberry pi 400 plus an HDMI screen, usb mouse, a solar charger and a powerbank (or two). I don't know if that voltage would be enough for it to read an external HDD via USB. To that we can add a smartphone using some FOSS android ROM like lineageOS or /e/, for handheld use when you don't feel like pulling out that whole rig. Then a piratebox of sorts - I think the piratebox project is dead now but maybe it has a successor that can work here. Maybe this box could house the hard drives, and the computer and phone could retrieve the stuff through SSH or some other type of connection. This can provide mesh networking, eventually. Setting this up with a directional antenna that points to some open or opened wifi can give you an internet connection. Plus USB speakers, headphones and all that. Wired or chargeable through low voltage solar.

Wardriving would probably be an important part of such a setup. Look up airgeddon on github or the AUR. Something like that but automated to perform pixie dust serially on networks from your backpack as you walk around your business in town. A script should automate all automatable web activity: downloading stuff like podcasts, blog posts and videos, updating your neocities anime tier list blog or whatever it is you have, etc. I think a command lie RSS feed reader that can send links to wget or youtube-dl for download would do the job. Unless you have a chill place to crash on and do the stuff manually, that is.

>>50967 One could set up a bus or camper with big solar panels on the roof.

>>50966 >- Can you design a bug-out bag that would secure your computing needs on the go? >- ... what about a long-term power outage? >- ... what about a long-term ISP outage? You are deluding yourself if you think you can sustain your internet addiction through such a scenario. Food, water and not getting raped by looters will be more of a concern than scrolling /b/ if there is a long term power outage.

>>50966 Android smartphone with offline maps, technical manuals on memory card, a wiki note-taking app, folding solar panel, USB power bank. Some knowledge or literature on how to build DC rotary generators for prolonged stationary use (water, pedal, wind), you should already have one powering all household electric needs if you don't plan to move. Everything else (soyberry Pi, 5kg Thinkpads, mining lithium for batteries and silicon for solar cells, soldering power bank circuitry yourself when there are free ones in literally every dumpster) is just a LARP. >long-term power outage If it's more than two days, your country is turning into Venezuela. If you're in city/suburbs, you're soon to be dead or sucking dicks for food. If you're in remote village, you can continue doing what you did, but prepare to kill bandits, and take urban refugees as serfs to work your potato field. >long-term ISP outage Go outside, find free WiFi, look up ISPs in your area, request new installation.

>>50990 How would a long term power outage prevent you from going to the grocer?

>>51001 just think about it.

You might be able to get away with having a toughbook with some PDFs on it for a few decades, but that would be the end of it. Conveniently, that's about the only thing that might be useful to you in such a situation.

>>50966 that backpack looks pretty comfy. It would be a great accessory to commute with on bike.

>>51004 Well I can't think of anything that spells complete doom to food. If you think of the food lifecycle as 1. make food 2. put it in grocer 3. go to grocer, 3 doesn't need electricity, 2 doesn't either since fuel, for 1 there probably are 1s that aren't so automated they wouldn't work during a power outage. What am I missing?

>>50967 I have a handcrank/solar panel radio that I connect to a powerbank via USB to charge a phone and run a raspberry pi router with a 4TB hdd connected to it. Does this count? I would take a picture but I don't feel like it. It's all cheap anyways. I have an old kyocera cell phone with the keyboard that comes out, but there's also a usb connector at the bottom, I think I can use a splitter to connect a keyboard and mouse to it if I wanted to. The only problem I could see is a desire for a larger screen...

I just want to say this thread is really cool.

>>51012 refrigeration And if you're going to live on cheetos and canned tuna, how do you think those are made and transported?

>>51012 >can't think of anything that spells complete doom to food. If you think of the food lifecycle as 1. make food 2. put it in grocer The part you are missing is how "make food" takes place at highly concentrated industrial scale and then the results are transported all over around the world with trucks and planes. There is not enough arable land for our current population to all do to their own diy farming and be self sufficient, especially around cities. And even if you did plan ahead and built a self sustaining farm somewhere. Unless the end of the world kills off large parts of the population instantly, you won't be able to defend it from hungry inner city thugs and their unregistered guns.

>>51029 Grains and flours are pretty much non-perishable and do not require any special conditions other than well-aired shelter. So are many vegetables. Transport is powered by fossil fuels, although gas pumps depend on electricity, and so do food production facilities, but if only one city is affected by power outage, it can still communicate with neighbors.

So, meshnets. I'm sure you can fnd some router that can be powered by solar, or maybe even by USB. Get a wifi network going, then you & frens can point directional antennas at it and get in. Now everyone's on the same LAN, and you can get games, livesteams, file sharing, audio/videocalls, chat, forums, practically anything without a need for an ISP. Just make sure to have the software downloaded beforehand: git clone all that soykaf. https://github.com/awesome-selfhosted/awesome-selfhosted When it comes to OSs, arch-based distros need to be updated often or they'll give you trouble when you have to download several gigabytes of updates and keep the thing on for hours as it installs everything, and then you have to fix ".so dependency not found" type stuff. So if you don't have a stable internet connection / battery charge, I'd suggest using debian, for real. You can hoard the .deb packages of the software you use and keep them in a flash drive. If there's no power, there's no printer (unless you found a 12v one, if so tell me about it) so you'll have to have your "suck my dick and I'll install debian on your pc" sign printed beforehand. >>51031 >>51012 >>51004 >>51001 Op here. Let's keep this thread closer to the personal tech setup idea, yeah? The conversation about food has been had before in other threads and the bottom line that makes sense ends up being something like: store seeds, grow your own food, build a group of like-minded people so you're not a lone nut to be looted by zombie-like people, start an intentional community. But maybe you should make a new thread if you want to go deeper into that because it would drown this very specific thread. >>50992 >If it's more than two days, your country is turning into Venezuela. If you're in city/suburbs, you're soon to be dead or sucking dicks for food. That's why you GTF outta there. This thread is about doing that in a smart way, without having to suck lots of dicks to get your tech game back together after you left your 5kg thinkpad behind because it's 5kg. >>51015 That's good, if one of these days you wake up feeling like uploading a photo, that'd be interesting. You do need to power the HDD caddie through USB, plus another USB port for transmitting the data to/from the rasPi, right? >>51029 >refrigeration For a personal setup (keeping cooked meals refrigerated for a couple days) there's 12v little refrigerators that I guess could run off a portable solar panel. I know: this thread is about what tech we'd have with us if we had to go live off a backpack. It's not about food storage or how to build a community or things like that. But we can share pdfs, youtube channels to download, or other media resources about such topics, and that would fall right into this thread's topic.

Here's a tool for offline use: Kiwix. You can download .zim files that contain information that can be read by the kiwix program (it's in the arch repos). So, there's a Wikipedia .zim file that's around 85GB. You download it, open it with kiwix and you get to browse Wikipedia offline. Same thing for stackexchange, the Gutenberg books and other sites. https://wiki.kiwix.org/wiki/Content_in_all_languages Beware, that website has a lot of content so it may hang your navi if you're low on RAM.

I second the offline maps and wikipedia pages you can do on android. Ultimately the goal would be to have something like solar powered LoRaWAN nodes that you could ziptie to trees every few miles to connect places together. As long as you are only sending short text messages you really dont need much power to send messages a long distance. Pine64 is working on making LoRaWAN nodes and creating an ecosystem of devices that use it. Very cool.

Here's an ultralight linux setup: If storage is very tight, you can get a smartphone, install a FOSS ROM like lineage, graphene or /e/, go to f-droid.org and install the app, open the app (while connected to the internet) update the repos and use it to install termux and anlinux (and whatever else you'd like). Alternatively download the apks from f-droid's website and sideload them. Open termux and run termux-setup-storage to give it storage permissions. Open anlinux and choose a distro to install on your termux terminal emulator: arch takes like 1.5 Gb but debian is much lighter. I recommend installing debian (unless you know you should go for something else), and then (once logged into your new CLI debian system) changing the repo (by editing /etc/apt/sources.list, IIRC) from buster to stable. Then do an apt update && apt upgrade, then delete the .deb files from /var/cache/apt/pacman (or something like that) to save disk space. Create your user and password and log into it. Now install whatever command line tools you'd need to cover your computing needs as much as you can. Maybe find a thread here about how to do everything on the command line (I'd be surprised if there isn't one on /tech/) and do your thing. I'd recommend learning some bash so you can make you own CLI programs that automate as much typing as possible (because smartphone keyboard) and work on a smaller screen (because smartphone screen). Happy fuarrrking hacking. If you have a smartphone with a wifi card that can work on monitor mode (you lucky bastad) install airgeddon and you're set. If not, set up SSH between your computer and phone (by creating a WAN with your PC and connectong to it with your phone, o the other way around) and control your PC from the phone (all of a sudden the picture of the bag with a fan in the OP makes sense - you SSH into the laptop you have in your backpack). Btw, afaik AnySense is the only FOSS keyboard that has that swipe option to type more ergonomically, if you're bound to working from a smartphone.

This thread is about doing that in a smart way, without having to suck lots of dicks to get your tech game back together after you left your 5kg thinkpad behind because it's 5kg. You know, that only begs the question just where those felated get the food in the first place and why not gank them for their stuff instead.

>>50966 >no connection to the electrical grid or the ISP grid. >Can you design a bug-out bag >inb4 more important survival stuff inb4 I'm going to stick to reality anyway and still make a valid post... Bug out PC designs for a SHTF scenario would be pointless. If you need to bug out then systems of stability have collapsed such that staying put is dangerous. (Based on your post style) your society's systems of stability are based on the electrical grid & the Internet. Therefore, if you are bugging out, the electrical grid and Internet (at least) have gone down. If you expand PC to mean "useful electronic devices" then a solution is: E-reader with survival material (you've already read & practiced), with extra battery/solar charging. Computers are dead weight in a survival situation. They only have use after stability is restored to some level. Though they are surprisingly decent at arresting projectiles, so improvised level I or IIA plates from a thin iMac laptop might be a thing. off-grid-japanese-cyberdeck-image-matching-OP's-thoughts.jpg (and a cat picture, because why not?)

Whew, this thread derailed quickly. OP didn't mention SHTF scenarios, only the concept of independence from the grid. Basically, you can use just about any hardware that fits in a bag and is waterproof. Be it a standard laptop or a custom cyberdeck, your choice. Power, if you don't want to leech off the grid, can be provided by battery packs, charged through the best method available to you. Depending on your local climate, that can be solar, wind or water powered generators. Regarding repair: not possible if you don't have access to spare parts and extensive knowledge on compatibility, parts specifications and what fits where. I'm talking about the actual electronic components, none of that plugnplay sh!t. When it comes to repairing generators, be prepared to provide replacement coils, or get one of those coil winding tools, with the winding counters, and find a source of fresh copper wire. Everything else is a matter of technique. If you want to go full off-grid, no accessing civilization, your best bet for computing is a robust calculator and a booklet with all formulas you may require. No joke. Off grid computing, without access to spare parts and electricity, limits your experience to 10 years, 20 years if you're having a good waterproof setup or a base of operations that provides a clean, dry atmosphere.

>>51355 I'm struggling to come up with a single command line program that would help in situation where you need to get out of city, scout for food and build a shelter. >>51360 E-reader devices have like half-second (kindles are the fastest) page turning latency, they are useless for non-leisure reading or any kind of data manipulation, front light consumes as much energy as AMOLED screen. Bad advice. Great reddit soyberdeck image, reminds me of 8/cyber/ circa 2015. >>51362 Are there relevant (e.g. not written in 1973) instructions on how to build a water/wind generator for powering small computers? What about Peltier units? I heard they go well with iron stoves or kerosene lamps, but become useless once you build a high-temperature full combustion masonry stove, should there be a heat-conduction circuit and a turbine of sorts in this case?

>>51360 > Computers are dead weight in a survival situation. > Though they are surprisingly decent at arresting projectiles A kevlar vest made out of thinkpads sounds like a good way for lainons to recognize eachother if soykaf ever hits the fan. "I recognize that GNU sticker". >>51368 >I'm struggling to come up with a single command line program that would help in situation where you need to get out of city, scout for food and build a shelter. $ minecaft Joke aside, obviously answering those questions was not the point of that post. Basically, what >>51362 wrote: >Whew, this thread derailed quickly. OP didn't mention SHTF scenarios, only the concept of independence from the grid. >Are there relevant (e.g. not written in 1973) instructions on how to build a water/wind generator for powering small computers? I think the first question would be if by small computer you mean one that runs on a 20v battery (like most netbooks) or one that works on around 10v (like a raspberry pi). In the first case, I don't know, if it's possible I guess it won't be very practical. But on the second case you'll find quite a lot of tutorials, I think. Charging a small battery with a small wind turbine and using it to power up a raspberry pi shouldn't be that hard to do, IMO. >>51362 >Regarding repair: not possible if you don't have access to ... That's a bummer but I think you're right. Maybe storing backup devices would be better. If you can make a bug-out bag, you can make three more and keep them in different places as backups, or to be used by other people if needed be.

Wouldnt it be a good idea to make a setup that any type batteries can be used to power the device if given enough power instead of solely relying on charging cables to charge lithuim cells all of which could eventually break down ? Also it should have hookups to be able to connect to any type of display if the built in display stops working. Then you also could ad redundancy having two drives with the same content both of which can serve to startup from. You also want to sheild this at least on the case level from water, fires and EMPs.

>>51462 A portable computer has to have easily replaceable charge port, always have spare charging daughter boards and sockets in stock or make an extender if it's an SBC board. Use magnetic adapters for Type-C ports. Make additional robust low-tech +- socket that plugs into charge port for easy hookups from any battery or charge controller. A smartphone is charged at 5V 0.5~1A, but needs special external circuitry to regulate current and voltage. Check if it can be powered from charging port alone, without use of internal battery. FePO4 batteries are the best long-life rechargeable batteries, good for stocking UPS, and as relatively portable extension batteries.

>>51462 Yeah, There are some designs around for battery powered powerbanks or plain battery packs, that you can build yourself. It's pretty useful, but in the end it's more expensive than a powerbank. >>51472 If it doesn't, one may try bridging the gap between the port and the battery connections. Such a setup would be pretty schway

>>51355 Is there an OOTB way to use airgeddon to "passively" obtain net connections?

>>51731 None that I know of, but if you know a little bash scripting it shouldn't be very hard to make one. Airgeddon is just a script that makes use of some command-line tools like aircrack and the other dependencies.

>>50987 I plan to do something similar but replacing the van with a sailingboat: Power: -wind turbine, solar and hydrogenerators to generate electricity -batteries as short term storage for electricity -hydrogen as long term storage for electricity (the boats engine would be electric as well ideally) Connectivity: -various radio antennas -satellite internet Repairabilty: -(metal-) 3D printer and lots of spare parts Computing: about anything works i guess It's less of a doomsday plan but just something I'm working towards in general and off grid computing would just be a necessity for that

>>53504 Check out these people https://100r.co/site/liveaboard.html https://100r.co/site/off_the_grid.html >-(metal-) 3D printer and lots of spare parts You've never sailed before and that's fine but you really should take a class with like lasers or 420s or whatever they're calling the two sail bathtubs these days, because I think your expectations are a little impractical. You are gambling with your life here and >-hydrogen as long term storage for electricity experimental technology like that is not something you want to rely on for situations where you're thousands of kilometers from help and the only thing between you and the reason ancient sailors refused to learn to swim is the thoroughly battle tested engineering behind your vessel and equipment. The 3d printer is just not going to work even on green water, let alone blue water even on the best days. >(the boats engine would be electric as well ideally) Last tear down but for the love of the demiurge please don't try and be an environmental hero. If you are living on a sailboat you are in the bottom 1% of first worlders' carbon impact. Your soykafty batteries are not just going to sink, they're going to need to be recharged. They're going to break, they're not going to be reliable enough to bet your life on. If you are in a pinch, just use the oil engine. The plastic containers of oil will float if push comes to shove and short of catastrophic failure, you simply put oil in engine and it spins and it can get you a certain distance that you can plan out for ahead. Gas powered motors are standard for boats and this is a situation where you want to stick with the standard. All that being said, this is a super noble goal and I wish you lots of luck. It's a life dream of mine to live aboard full time before I die.

>>53816 Why do you answer to underageb& LARP post? Why did you link LARP webshotter? >In 2018 while in new zealand, we spent around $10k on Pino Epic. I didn't spend as much on my house in 10 years.

Good flexible solar technology is becoming more affordable. An 80W CIGS panel is available for $250 - $300 where they used to cost $1000 or more in recent years. Are the panels packable, along with the portable power stations and cabling? Not yet, maybe with a massive 100L backpack and about 20lbs of weight you can't use for anything else.

>>54079 I should add some advantages as semi-portable power generation: - They lose less power generation when partially occluded or in shade compared to other cell types, so they are less restricted by overcast weather and low sun hours. - Resistant to kinetic damage, and will continue carrying power around damaged areas of the panel. CIG panels have been shot by low power small arms and continue to generate power without severe loss in generation.

>>5408 To add to my claims: https://yewtu.be/watch?v=rsZH0iv9zm8

>>51360 have a build guide for that portable pic? especially that case also sticker?

I have a small usb based solar cell with builtin battery, i want to make it shoulder mounted so i can carry it. Usb portable solar cells always seemed impractical for that very reason, you either have them in your bag when moving, and when not you have to deploy it some place proper. I also like to make myself a proper deployable solar cell in a suitcase with a aluminium casing. Its nice you can use usb for lots of stuff, the 5v range is pretty universal, also having 12v stuff is great too. Also there is lots you can do just by wiring batteries together.

>>54128 >I also like to make myself a proper deployable solar cell in a suitcase with a aluminium casing. Have you already in mind some specifications? Which type of cells you'll use? How many Watts will be able to generate? How much it will weight? Just curious

>>54129 I have no idea, all i got is a big ass solar cell in a plastic casing, but i want to make it metal so i can do actual outdoor use. I really have no idea for specifications of any sort, its not like i need much, just enough for 5 or 12v of some sort will suffice.

>>50966 Good idea but it's dumb to think that you'll be able to maintain this setup during an extended power outage. Would make sense more to have a setup that occasionally connects to the grid to recharge and grab some stuff to be viewed locally.

>>50966 I have gone off grid for small periods in last few years during summer, when the climate is forgiving. 1. Solar powerbanks are mostly very slow and thus useless 2. Your phone is a very useful tool, esp with termux installed. I got an LG G8x with the case that can do most of what I need. 3: I used a Surface go 2 with linux installed before, this worked really well because I could charge it with a powerbank. I was carrying everything in a backpack on a bicycle, so I couldn't carry portable generator's I need to figure out some kind of setup, that works in countries with sunlight that is not strong.

>>54147 >so I couldn't carry portable generator's I need to figure out some kind of setup, that works in countries with sunlight that is not strong. Idk if you stay mostly stationary in one location or you travel several hours on your bicycle. If the latter is the case then you can use a bicycle dynamo to charge a battery bank. Nominally a bicycle dynamo generates 500mA @ 6V AC and behaves as an AC current generator. Considering an average phone's battery capacity on 3'000mA*h @ 3.8V you should be able to completely charge in about 6 hours of pedaling. In reality, the bicycle dynamo, is composed of a AC voltage generator, a zener diode and an inductor. Like pic but with a zener diode Maybe it is possible to make it generate more power https://keith-snook.info/riaa-stuff.html https://blog.andrew-lohmann.me.uk/2020/09/electronics-design-project-bicycle.html

>>54149 In completely stationary situation a floor-bolted pedal machine can be built. Not only can it deliver electricity, but also power mechanical machines like pumps, mills, drills. In semi-stationary situation a special heavy (to retain momentum and deliver smoother voltage) rear wheel attached to generator rotors with a chain could be used. An even more compact city apartment or small cabin design would be to use existing bicycle rear wheel, perhaps maybe with a separate smooth tyre to roll on the cylinder attached to generator. An example on video: /watch?v=Q05NISGYYJg A relatively inexpensive TEG can be built from Peltier plates, it generates electric current from temperature differences: https://arambartholl.com/old/5v-eng.html https://web.archive.org/web/20211021021328/https://www.lowtechmagazine.com/2020/05/thermoelectric-stoves-ditch-the-solar-panels.html An article on history of early PV solar cells: https://web.archive.org/web/20211123052530/https://www.lowtechmagazine.com/2021/10/how-to-build-a-low-tech-solar-panel.html

>>54152 An old exercise bike already has a flywheel and would work for this. It probably already has a mechanical tachometer, or you can add a cheap opto-electronic one to measure your cadence for optimal power input. Also, here's a charge controller from that video: https://mdpub.com/555Controller/

>>54152 >Not only can it deliver electricity, but also power mechanical machines like pumps, mills, drills. (x) doubt The average adult outputs 100W when pedaling. The equipment you mentioned require 1000W to 2300W. Well, small drills use 25-100W so they are feasible. but at that point you might as well use directly an hand drill. Even though if I have to drill through rock I'll prefer to pedal 1 hour, charge a battery and use a power-drill for ~5 minutes than trying to make an hole in the rock with an hand drill XD The same goes for the pump, I can directly put my mechanical energy into an hand pump >A relatively inexpensive TEG The TEG1-12611-6.0 costs 50USD (!)

>>50992 >If it's more than two days, your country is turning into Venezuela. This would probably only apply if it were the entire country in a cyberattack or something. There are regional power outages that last a week plus all the time due to hurricanes and paid fellatio is not common in these situations. >>51360 >Computers are dead weight in a survival situation. Civilization itself is a survival situation, and computers are very valuable for it.

A settlement that is cranking out firearms and metal tools, issuing scrip, and maximizing crop yields is going to conquer one that is whittling wood spears by hand.

>>54298 3D printers rely on industrial supply of electricity, plastic filament, precise machined body chassis and microelectronic components. 3D printed firearms are sort of LARP and yearning for potential future dystopia (as seen on TV) situation when you can't own lower tech machine equipment due to noise or occupied space or skills needed to operate constraints or higher traceability of ownership by law enforcement. However, still lower technology equipment allows manufacture of better firearms than equally priced 3D printing, you can build revolvers with XIX century muscle-powered tools and already existing supply of pre-manufactured metal parts. Biggest obstacle often overlooked by LARPers since they live in countries with relatively relaxed firearm laws and are just flexing their "2nd amendment" is manufacturing or purchase of reliable projectile ammo or components needed for it's production: explosives or explosive "precursor" chemicals. It is often said by devious yet smart people, that to ban firearms you should ban ammo sales. No reliable ammo = no working firearms. One can produce a better firearm than say a plastic "liberator" pistol out of metal pipe and shotgun cartridge sold freely in hunting stores even in countries with "strict" gun laws. You can add multiple such boomsticks into bundle making a pepperbox. A revolving pepperbox which aligns with extended barrel is a revolver. Not to say that modding already existing "deactivated" prop guns or non-lethal firearms is much easier than manufacturing from scratch. Or buying real firearm with ammo (in walmart or darknets) and making a treasure box dead drop somewhere in a forest for times to come. To summarize: in out of grid situation and without working government, operating a mechanical non-electronic gunsmith shop would be much easier than a high-tech 3D printing facility or whatever similar reddit ideas you guys present here.

>>54325 McFucking what, where's PDF?

>>54149 I was travelling for 6-8 hours daily. I tried a bicycle dynamo to charge my phone, it is pretty cool I have to admit. But the other bicycle I have which is lighter and better does not have the dynamo attachment, and adding it would mean soiling the integrated steering.

>>54336 >does not have the dynamo attachment, and adding it would mean soiling the integrated steering Using a bottle dynamo for 8 hours straight is idiotic anyway for power efficiency and for the tire health. You should definitely consider a hub dynamo. Even the soykaftiest Shimano hub dynamo has a power efficiency much greater than the best bottle dynamo https://www.cyclingabout.com/dynamo-hub-drag-lab-testing/ Cons: - expensive, especially the lighter and efficient you go - lower AC frequency is generated so the lights may flicker at lower speed. It should not be a problem for charging a phone with a buffer battery Of course you'll need to build a new wheel for the hub if the wheels with a hub dynamo on the market don't satisfy you

>>54325 >industrial supply of electricity I have solar panels, wind generators and water turbine in little water turbine on my creek in my land (theorital ofc) >plastic filament I buy PET bottles and extrude them into filaments >precise machined body chasis I have my shop with all tools to make my own >microelectronic components I am electrical engineer btw these are all theoretical but you're just a LARP btw I don't have solar panels or turbines myself but alowing for all this to be made by me and having blueprints is enough for me to totally get off the gid

>>54344 >I don't have solar panels or turbines myself but alowing for all this to be made by me and having blueprints is enough for me Are you saying that you have the technology to produce photovoltaic cells and other semiconductors in your shed? 😂😂

>>54352 if you were to look it up it aint that hard, but even then I can make a simple wind turbine no problemo

>>54711 lol'd at this grandpa who saves web pages as paginated pdfs.

>>54751 at least he can still consult them if he's off-grid. Plus a PDF is a single file, compressed, no problems with fonts or alignments on different browser and if he needs to, he can print it

>>51553 might be worth it to have a dedicated radio-- better battery at cost of more bulk and using radio wont kill computer. pinephone has a pretty poor battery life, but you can swap batteries for quick charging on the go. >>54147 i have a battery that says it puts out 2.1a, charges my phone in few hours. >>54751 some of us have been bitten by bitrot

>>54751 >lol'd at this grandpa who saves web pages as paginated pdfs. Use Tesseract to convert the text into a searchable PDF.

>>55221 Paginated does not mean flattened (if that's a correct term for making a screenshot of text). Pagination looks like someone took a web page which is a continuous computer screen document, cut it into silly looking A4/US Letter rectangles and arranged them in front of you as pages of a book. This is how it is displayed by default in any regular PDF viewing software because this software usually deals with books, presentation slides and albums, which originate from, or designed to become print media, not web pages saved by an idiot. A better choice would have been to save a web page as single page PDF document since format allows any kind of page aspect ratio. The downside would only be terrible width, one it was rendered in originally, most likely an awful 1920 dots wide fullscreen browser window.

>>55229 >cut it into silly looking A4/US Letter rectangles and arranged them in front of you as pages of a book If the website has proper CSS for printing, an article printed paginated in PDF does not look silly at all Of course most of the web sistes don't have a specific stylesheet for the printer and it looks silly. This very page is an example
