Just a quick update. This prosject is not dead, I'm just waiting for my PI to arrive. I ordered from RS online in february, still no sign of the PI. I have a friend which just got his PI from Farnell, even though he ordered 2 months after me. So I've just ordered from Farnell, they promised to send me one within 5 weeks! So stay tuned for updates.
I've also ordered a TTL controlled Relay from Robonor (Norwegian Sparkfun Supplier) for controlling the power on the machine.
