Thomas will be showing off (and playing) the electronic drum @ Maker Faire, he writes…

A guitar string is suspended above four strips of aluminum tape. When struck with a drum stick, the string touches the aluminum tape, closing an electric circuit that triggers an electronic drum. Foam covering the PVC pipe softens the blow and provides a nice bounce.

The switch closure is extremely fast so a pulse stretching circuit (resistor and capacitor) is necessary to lengthen the pulse to trigger a drum machine or computer keyboard.

Carlos is an engineering student at the National Hispanic University (NHU), San Jose, CA and is the teaching assistant for the Electronic Drum class.
