Carpc's are a hobby of mine...big brakes, suspension and Carpc's are my usual modifications...
There are 2 major components to "car pc" . the "pooter" and the "input devices....A LOT more information can be found at mp3car.com
I bought an "8in 12 volt LCD touch screen", fabricated and painted the bezel out of acrylic sheets, got power from the cig lighter
The "pooter" is an IBM x60 on a dock and it lives under the passenger seat....basically ran VGA and RCA cables from the center console under the seat. I got a laptop car charger and ran power directly from the battery (with fuse and switch of course)
Alas I there is one shortcoming...the climate control as what's his face asked about...If i had more time and brains...I would've ran the climate control off servo motors controlled by the computer but I live in Northern California weather is pretty consistent and nice. sooo I completely deleted the mechanism....
There's a cable that controls under the glovebox which I plan on adjusting twice a year
There's another that controls the venting on the driver side...I plan on leaving that on legs and defrost but cable adjusting is easy to do
I plan on splicing a rotary switch to the Climate control wiring harness so I can turn the Fan on and off...so if anyone had wiring diagrams that would be awesome
i'm sick, more pictures soon...k bye
