That's awesome, do you have a video of it solving the cube?

Sorry no, I haven't had any video-recording devices, it's partially in bits (my creations were lucky if they lasted more than a day) and it's 180km from where I am now. There's a similar robot on youtube ("lego rubik").

The most interesting thing I did was a mechanical pendulum clock, great fun. Requires no motors, just a long arm and a clever tick-tock mechanism.
Meh, I want all my Technic boxes now

Heh, I've always had an interest in escapement mechanisms, and seeing how long I could get a clock mechanism to run in Technic.

My best attempt only runs for about three minutes, though, before winding down. It used one of those elastic band and reel sets from the pull-back-and-go cars to store the energy. I'd be interested to see your design...

I used the good-old string-with-weights method as in cuckoo clocks, which gives, uh, "time-independent uniform forces and pressures on the internals". I never figured out a really, really good escapement thingie, they either were too delicate and unreliable or too coarse which let too much string pass by. I gotta build a new one at my parent's around Christmas
