what are some tech modifications I can make to a car? I'm looking for something practical that also looks cool I'm considering building some kind of dashboard with a raspberry pi for the front console. Besides maps, and other obvious things I don't know what else it can be used for. Have you made any tech modifications to your car?

- ejector seat with parachute - oil slick - spikes shoot out from hubcaps - EMP blast - smart missiles that can read a license plate and home in on target - fuzzy dice

>>8697 >- fuzzy dice not sure, seems like too much

Look for obd2, if you haven't yet. It's a standard to read ECU parameters from a car, so you could grab data and build a performance dashboard, or maybe build modes based on historical data from your travels. Low-budget setup usually deal with ELM37, but beware of its lack of surge protection circuit.

>both guns mounted on the left bothers me for some reason, seems very inconvenient

>>8703 the only convenient mounting surfaces visible are left. Presumably there's more guns we can't see, such as on the right.

Mycroft virtual assistant. It's open source. I want to say high definition sonar with a HUD but Im not sure you can do that effectively to see through fog. Also in theory you could make a GPS free navigation system if up used road maps and image recognition of street signs and a magnetometer.

Radar detector is pretty obvious and also pretty useful.

>>8709 Is there a different between HD radar and 4D radar? Latest news has been talking about these for cars.

Lol, show me a freetard nav software for Linux that works on any present day OS version and has recent map tiles and routing data.

>>8736 feds probably have something but it isnt free lmao

>>8736 >freetard I meant free of GPS not financially free as that's an implied given. I hate to make what appears to be a low effort post but without an in depth knowledge on that best I can do is a list I came across that was written current year. At least one of these could be both open source and an active project id hope. https://www.bollyinside.com/articles/best-maps-and-navigation-software-for-linux/ It inded is possible to do navigation without GPS. For example this company is selling one such system. I had not looked this up prior just happened my idea has already been done. https://www.roke.co.uk/innovations/accurate-location-and-navigation-without-gps

You can try recreating theese viseos, they're Russian lang though. https://www.youtube.com/watch?v=wnQuzA5WPP8 https://www.youtube.com/watch?v=EK14AHH4I84

>>8700 what the fuarrrk is that soykaf

license plate reader a system which keeps track of when lights will change, so you don't have to worry about red lights

>>8751 That article looks like SEO spam autogenerated by Indian bots. >do navigation without GPS This is not what was meant. Simply put, there are no fully offline navigation programs that work on GNU/Linux. For Android there are hundreds if not free as in freedom, then at least easily pirated/cracked and functional enough to support multiple data formats for map tiles, offline route-building, POIs and so on.

>>8781 calling GPS 'online' is a bit misleading. you can run perfectly fine GPS systems without an internet connexion. Not sure about linux programs for it that give you more than latlong but GPS itself sits outside of the internet. so download some relevant maps and setup a simple GPS system, or buy a good old fashioned GPS device with maps included. No need for the 'net.

You guys never used OsmAnd+ (Open Street Maps Android Navigation Directions Plus)? https://f-droid.org/en/packages/net.osmand.plus/ It's free as in freedom, works offline, and doesn't waste time with "recalculating route" on some random server meant to track you, doing it nearly instantly on my device whenever I go off route. I used it on my more freetard years, but stopped because, honestly, I know my town too much to need it.

>>8781 I thought it was a reply to something else I said because I mentioned prior to that post about the idea of trying to build navigation without GPS by using maps uploaded as needed only and using image recognition of street signs, a compass to get orientation and perhaps a sensor to estimate speed. This is only something someone would want to build if they are concerned of their GPS location being logged at any time or if they plan on going somewhere GPS signals get blocked easily such as in forested valleys and long tunnels or severe weather conditions. It wont be as accurate as GPS but it beats using a map if you have bad memory and focus.

Do you mean purely digital modifications like those raspi things? They do sound cool, but the obd loggers aside imo just distract from the driving experience that i myself enjoy most. From ALL the modifications I have made to my car, the best must have been a new 2-DIN bluetooth head unit to replace the old audi rns-d, a 2x12" 2500W subwoofer, a turbosmart in-cabin boost controller (and of course a boost meter with backlight matching the red light theme of the car) and the most amazing of all; window tint. window tint is amazing, nothing makes a car more comfy than the darkness it brings. What i'd like to see in the future is people learning to hack haldex clutch controllers, the only thing blocking me from buying an audi TT, or some new volvo with 4wd is the low reliability and poor fun factor in stock haldex systems.

>>8789 I don't use the route finding feature but its a really useful map nonetheless. Tends to be much more responsive than google maps too.

>>8696 Honestly I would be more concerned with taking tech out of my car rather than putting it in. I am quite concerned with the shelf life of all the electronic gidgets and gadgets in my car and am concerned at what I am going to do when they break. Luckily most of the dashboard is still analog. Is there any resources to retrofit analog gauges onto a digital dashboard or are you just fuarrrked 10 years into your cars life when they go out.

>>8802 >Honestly I would be more concerned with taking tech out of my car rather than putting it in. I am quite concerned with the shelf life of all the electronic gidgets and gadgets in my car and am concerned at what I am going to do when they break. This is a great point but the OP is asking about tech to add which makes the set up much more modular than what comes in a modern stock car.

>>8770 Do you mean the pic? MEMS hex values, like gyroscope, engine temperature, soykaf like that. Depending on your vehicle tech level, you may grab a bunch of data, like battery voltage, fuel consumption, GPS stats, etc. OBD2 is pretty schway.

>>8818 If OPs car lacks it, tire pressure would be useful data to ad. I dont know how cars do that normally though. Are they actually measuring the tire pressure or just using some sensors to estimate based on how the car sits on the road?

>>8826 it is my understanding that these are usually physical sensors on the radio that communicate with the car via radio

>>8709 and illegal in many countries

>>8839 was about to say, if youre looking at useful features to add a good place to start could be the spec sheets for modern military trucks and acvs: self inflating tyres and changing tyre pressure to match conditions are pretty common in military vehicles now and have some stock civilian kits you could at least look at to clone, while other urban cobat features like independent suspension and 360 degree camera setups could be used as well of course, theres nothing stopping you giving your car the ability for add on armour kits and automatic fire extinguishers as well :)

>>8696 I also wanted to do something like this recently but I have doubts about power consumption. My car is a pretty soykafty palio with 1.2l engine. The previous owner installed a camera, a radio, and a sound system (very messy job, all cables are dangling around) and i was thinking about maybe putting an old android tablet on the console instead of the radio. But i don't want to kill my car's battery. How do i know how much it can handle?

>>11132 why not get a seperate battery for the gizmos, or try it out and upgrade the battery if its a problem. >>8816 thats a neat idea and I like it. obviously some drones can go at highway speeds. Rendezvousing with a moving car sounds tricky though. Will need either a lot of automation or likely a second guy in the car to operate the drone. Legal status: idk but maybe fine lol >>8802 the reason I hate computech in cars is because its done soykafily and shoved down your throat by idiodic regulations. DIY is fun though so why not.

>>11133 >the reason I hate computech in cars is because its done soykafily and shoved down your throat by idiodic regulations. DIY is fun though so why not. Totally there is a huge difference between a car built around a computer and computer built around a car.

Pwnagotchi with a big ass antenna. Other war driving equitment.

>>8700 I'm assuming you are already a solid mechanic? If not, start with the mechanical systems and then move to electrical. If so, go straight to CAN since OBD2 is just the government mandated CANbus breakout. https://archive.org/details/thecarhackershandbook Second, stay away from vehicles post 2010 if you can. The future of automotive shenanigans revolves around garage builds and small run stuff. Government doesn't mandate the invasive stuff on these and you can still register and insure them. 2010 is good because most autos from that year have a full CAN bus control system + all the fun modern digital control systems. You can add infotainment, sensors and cameras yourself (and keep them off the net). Finally, check this out if you're wondering why all this bus stuff is so interesting. https://github.com/commaai/openpilot

> what are some tech modifications I can make to a car? You could install a solar panel on the roof that charges a heavt duty battery in the trunk. It would have to be done aerodynamically so it doesn't fly off. Then you could install lights and other things that use power from the battery, without wasting gas or depleting your main car battery. Maybe even an inverter. A van would be ideal for this. You'd have a portable party room with electricity.

>>8696 >tuner w/ display >turbo w/ gauge >shot of nitrous >pneumatic suspension >>8697 >shot of acetylene >smoke screen >James Bond-style machine guns >>8816 >>11482 >periscope >>8802 You can read the engine speed from the ECU. If you plan on going purely mechanical, no reason you couldn't use old school tachometers. >>8973 Hide it >>11437 >solar panels The power the car wastes while idling is probably significantly greater than what the solar panel produces.

>>11496 >periscope Yeah, something like that could work as well. Only question is, where would you actually put it, and how big would it had to be for it to be comfortable to use. If you where to hook a camera, you could see what the lens receives through a screen, maybe, whilst with the periscope, you would have to get reeaaally close to it, and, depending on the situation, it may be either uncomfy or just dangerous. Please lain, give more details about the periscope. Where would it be hooked up, all of that.

>>11504 >center of mass is still going to be in the car so its ok it won't flip you over I more was thinking of it bending or breaking. >are there any cars that don't open the vents every so often even when its on recirculate ? I dont know let me tape some doors shut and see if I run out of air lol >I hope thats not a problem for you but if it is People falling asleep behind the wheel on long drives happens more than youd expect. Particularly on long straight highways because it becomes sort of hypnotic the sounds and light alternation etc. >hot indoors. I suppose yeah it would still warm up but take longer to and no scalding hot seats and steering wheels.

>>11502 here >>11503 >>11504 would it be too bad of an idea to use radio signals in order to track the cars surrounding you, whilst making a computer render them in a 3d environment? i'm trying now to use only things that you would already find in a newer car, (radio, an onboard computer, you lains know) of course, making an exception for software, which would have to be developed first. only question i have is, how do you see the streets on the screen, because as far as im aware, concrete doesn't send radio signals. that and, what about interference. if any lain knows, please do explain.

>>11513 >Or you're instead talking about something to guess radio signal locations? Yes, i was talking about radio signals. >I think that would not likely be very accurate and radio signals can bounce off of objects I thought so, thanks for answering my questions lain. In any given case, could it be feasible taking in mind the limitations that i put on the table? (just for the sake of it of course) >i'm trying now to use only things that you would already find in a newer car (making an exception for software) Could you use whatever is in the car, without attaching anything else to it (hardware wise), in order to identify things that are outside of your field of view, because of, say, tractors? And lets say that this thing is radio frequencies; how inaccurate would it be? My car has no 4d radars installed by the way.

>>11514 It might be easier for you to look for wifi and blutooth signals because they have the identity of the devices which would be uniquely identifiable so it would at least not get so mixed up with other cars. This would be patchy as not everyone has their wifi or Bluetooth turned on their phones. How accurate this can be would depend on how many antennas the car has for this since a single antenna for bluetooth means it would only be able to pick up signal strength to guess range not direction unless you used some sort of AI to guess direction based on changes to the signal strengths from from driving by having a sensor to detect your speed or geolocation but this seems like it would be quite difficult but I think it's doable.. >Could you use whatever is in the car, without attaching anything else to it (hardware wise), in order to identify things that are outside of your field of view, because of, say, tractors? Assuming the dash has an android auto system on it I think so otherwise it would be more difficult. Cars usually have Bluetooth connectivity, but for wifi you may or may not need an adaptor that plugs into the car's cigarette lighter outlet.

>>11515 This one is a really good idea in my opinion, since most cars nowadays already have either bluetooth or wifi on them, and is somewhat actually capable of happening if somebody with the knowledge gets to it.

>>11516 Down side is it potentially leaves you open to beacon tracking so ideally you want something to randomize the identifier of the car periodically.
