Oscilloscope on the way...

Still having problems with the servos. Not sure if its the control wave being sent from the microcontroller or if its the servos. The oscilloscope should answer that for me. It will let me check that the signal I am generating is what I expect.

Luckily there are digital oscilloscopes that are much cheaper than their old analog cousins. I found a pretty decent looking one which should be quite sufficient for the type of work I am doing.

By the way, who would have thought that such a small servo could produce so much smoke?
