Ebay mixed bag of robot bits

I mentioned on SPANR's page that I bought a bunch of robot bits on ebay some time ago and I started playing with them recently. This blog is my way of keeping track of what I got and some thoughts on what I can do with it.

First off, the biped.

Magic blue smoke

As part of a mixed set of robot parts I bought on ebay I received this Dagu 4-Channel Motor Controller. On the back there was a trace broken so I soldered in a wire to replace it and hooked it up to the Rover5 (from the same set). Wired it to an Arduino UNO and programmed it to run a motor test. Applying power to the board, before the Arduino had even started PWM, one of the driver ICs began smoking.
