Just got done with this one spur of the moment.
I was reading about piezo transducers believeing I might be able to combine them with a future project. This is a proof of concept type of thing, don't laugh too much. A fancier version would use a real drum pad, a piezo transducer, and a cord with a headphone-jack.
