I’ve been looking at the Arduino for the past 2 years, and I really have learned to love these little things. They’re a great open-source development board based on Atmels wonderful ATMega line. I use them for anything between powering servos to vehicle instrument clusters.

I’ve also started making small breadboard versions for sale based on the Ardweeny line, which houses the same power as their bigger brothers (Although are a bit tricky to program for if you don’t have a breakout programmer!), although it’s very possible if you have a Duemilanove / Uno using the ArduinoISP sketch – It’s how i upload code to mine!
