Plan is for it be running off of a $35 Raspberry Pi
+ $10 OBD-II STN1110
+ $20 GPS chip (Pharos GPS-360?)
+ $5 accelerometer + compass (LSM303DLH or ADXL335).
$80 gives you a computer with HDMI and RCA video out for your head unit. I want it to be touch / interface optional. So you can set it up at home and then take it out to your car and hook it up to a non-touch enabled display.
Anyone know how to program something like this? Anyone want to partner up?
Planning on ordering the rest of the hardware soon. I'll go piece by piece. Probably get the obd2 and accelerometer + compass. Hopefully I can get it where people follow a hardware tutorial and download a sd card image or run a bash script. I'll try to keep this thread updated.
Oh I forgot to add. You set a home location. Every time you arrive at this location it will attempt to connect to your wifi network and upload the log file to a dropbox account. It will then run a md5 checksum on the local version and the dropbox version to verify that they are the same. You wouldn't have to take out of the car to read the log file.
Just found a tutorial for the cheap ebay GPS:

Got a team going. Programmer and engineer have been sourced. This might actually become a real thing!
