The other thing I want to add is that there are tons of things he can do as well. A lot of things today have embedded systems in them and a call to the manufacturer or poking around on the web can get you access to the embedded system and you can reprogram them. Just giving him the hint that there is a computer in just about everything will send him off on a tangent.

I would also let him take some classes in basic electronics at the CC as well. Soldering something together is great fun!
