Digi-Comp II

You can now get a wooden version of the original Digi-Comp II which can add, subtract, multiply and divide binary numbers using marbles. It's both educational and mezmorizing.

For under $300 it's pretty tempting.

I was sure I had posted this earlier, but the Yuri Suzuki Tube Map radio is excellent.

Particularly like some of the modified station names; Oxford Circuit, Earl's Coil, Clapham Jumper, etc.

littlebits look really great - much more accessible than the arduino type stuff, and a better scale than the big white blocks (anyone remember what they're called?). can't wait for them to retail!
