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.

First Hand Made Drum

This is video of me playing my first hand made drum - put together out of scrap laying around the shop.  The drum sounds good, I just suck as a drummer.

Compressed Air Rocket Launcher

For my son's birthday I built this launcher using plans from Make:Projects.  One shot from our driveway went about 150 feet up.  I was pretty surprised.  Tomorrow we take it to the park to see what she's really got.
