You could try grabbing a cheap microcontroller to do what you want, one that does RS232. Then you can communicate with the micro from the Pi, and use the Pi as an in-car computer for GPS and such, as well as displaying engine stats.
... Although, if you want video and stills capture as well, with a camera the Raspi could handle the entire system for you - sensors, data logging, GPS and imaging. Just using a Raspi camera would save a lot of weight over a separate compact - enough to offset the higher power requirements.<br/> ...
... some form of heater. It depends if you only want thermal data, i mean How do you plan on tracking the balloon? do you want live radio telemetry, GPS? video feed?<br/> <br/> <br/> Thermal data is a start but it would be any kind of sensor the school project wanted. It could be dust, gasses, temperature, ...
... you should verify that and not take my word on it.<br/> <br/> So if you've got a touchscreen in the front of the vehicle with your media controls, GPS, etc, then if you want to play a video on the rear screens then the front would just go blank (or if I'm wrong and mirroring is indeed possible, ...
... extra components, which may be in the following system.)...<br/> <br/> Exo-vehilecular monitoring or "car eyes".<br/> This is bacically using GPS and vehicle-to-vehicle communication but could also include a vehicle-to-pedestrian type too. Google have made a system like this but IMO its a ...

... HDMI video outputs independently, I'm wondering about using a pair of raspberry pis. A typical automotive use would be one display for control, GPS, etc, and secondary display(s) showing video in the back of the vehicle.<br/> <br/> Having the master device control the video-playback-only device ...

you need to insulate and potentially use some form of heater. It depends if you only want thermal data, i mean How do you plan on tracking the balloon? do you want live radio telemetry, GPS? video feed?
... there is electrical seperation between the 12v lines and 3.3v inputs.<br/> <br/> Once you've done the initial bit then I'd suggest hooking up a GPS reciever and screen so you can see exactly where you have ploughed (wonder how an RPi would compare to the commercial versions of these systems).<br/> ...
... recording live engine data. It believe it has an OBD2 interface so will need to check what thats capable off.<br/> <br/> I was thinking of adding GPS for tracking and some discreet security cameras. I'd record the data locally and maybe have it sync data with my Android via bluetooth or wireless ...

<t>DROID on RPi would rule as a car pc project(This is what i intend to do), as a home device im not so sure.<br/> <br/> all the things like GPS Radio and everything else you would need is available as usb dongles.<br/> <br/> there is a box being sold by maplins that runs droid and is a freeview ...
... <br/> It has been mentioned that the 3.3V current output at the expansion header is 50mA.<br/> <br/> <br/> 50mA is too low for my application. The GPS alone needs around 80mA. Looks like everything will be powered from the external switching regulator</t>
... all about device integration - of course it SUCKS as an OS. Why would you even want it on the Pi? You don"t have access touch screen or camera or GPS or the magnetic, light, acceleration and orientation sensors (throw a Pi across the room and the first you do is pull all the cords). Let Android ...

... about the hardware for all of this. At what point are we overloading the USB bus? Can it handle being hubbed out to 6 USB ports running a mic, gps, bluetooth, wireless, keyboard, and mouse all at the same time without causing problems?<br/> <br/> I am assuming the DSI interface is considered ...
... <br/> I envision a Raspberry Pi providing the main guts of the smartphone, as well as an LCD touchscreen, CMOS camera with flash, USB Mic, USB GPS module, USB Bluetooth/Wifi a/b/g/n module, and USB GSM data modem(with a data-only plan,.. going VOIP-only for simplicity and cost I think.).<br/> ...
