Fascinating stuff, thanks for that.

I've done a bit of playing with Arduino boards, I'm currently wondering whether another approach might be to mount a full-function computer like a RaspberryPi into the car, then it could provide a range of other services like GPS and data logging as well as driving the temp gauge?
