I've been scoping out a few odds and ends pieces at S@H, and was hoping to buy some turntables and some chain drive to try building my own syncro bot.

I built a simple solar-powered hexapod last weekend with some new parts I ordered from Pitsco. The walker is quite slow, using the LEGO solar cell to power a 5225 9V motor, which drives a worm gear coupled directly to a 24T gear. I've found the LEGO (...)
