Build Your Own Electronic Drum Kit
Talk about Do-It-Yourself (DIY) machine, Nathaniel Andrew gives step-by-step instructions on how to build your own electronic drum kit:

I was tired of using my Evolution MK249C MIDI keyboard controller to enter my drum parts. I have wanted an electronic drum kit for quite some time, but could never justify dropping any serious coin on a set because I am a terrible drummer. So… being the DIY kinda cat that I am, I decided to just make my own.

All you need is a Radio Shack Piezo Transducer (273-073A), a Radio Shack Shielded Phono Jack (274-346), a soldering iron, liquid flux, epoxy, an xacto knife, a 1/4″ drill bit, a 26awg 12″ x 24″ plate metal, cutting sheers, and 20 minutes of your time.

I would love to try this some day.
