[sdiy] Time for a NEW string - Piezo Switches!!!

[John Blacet]

The best way to think of piezo is to compare it to a microphone.

It reacts to impulses or hits with a pulse amplitude proportional to
impact. It's difficult to get a pulse out that lasts for the duration of
contact; that is really the function of a switch.
