My builder-boy is 10, so I've been through this. It's so hard to stay a step ahead of him. Do you know about Make magazine? It always has fun things to build.

I assume has has a Lego Mindstorm? If not, that is a level up in complexity from Legos.

What about Mousebots? And other robot-things that must be soldered together?

My builder-boy also likes RC cars-- he's into the high-end ones because he can exchange parts and make them better.
