Anyone for a slice of Pi?

Coming along nicely (almost segueing into) my last post, here's the same idea, 20 years later.

http://www.raspberrypi.org

A tiny credit card-sized single-board computer aimed at teaching kids (and anyone else) about old-school computing, growing-your-own code and building your own kit.

What really attracts me to this one is the provision of an analogue video output, which I could hook up to one of the old 6" LCD screens I've been messing with for about 2 years. I'm thinking of a 20MHz PIC like a 16F690 to collect raw engine data down at the ECU and to send it via a long USB cable to the cabin where a Raspberry Pi running TinyCore and my own Gambas program would decode this into graphs and charts. Rather than a touch display, I'd like to revisit the old Renault Laguna stalk controls, but via another PIC (maybe a 16F628) and USB so the control buttons have some degree of 'intelligence' for the computer to interpret.

Getting closer, but oh so slowly!
