Drum Electronics

This is a start on electronics for my drum.  I use an Arduino clone, an Adafruit PWM board, and a piezoelectric sensor to implement the lights.  The software is really straight forward right now, just implementing what is in effect a VU meter.

If you look carefully at the video, you can see a difference in the circuit's reaction between the beginning and the end of the video.  Right now I've just got the piezo stuck to the drum head with electrical tape.  After playing for a while, the sensor looses some of it's connection to the head, and the sensitivity goes down.
