The Springboard: The Joy of Piezo Disk Pickups for Amplified Coil Springs
Abstract

The Springboard is a do-it-yourself instrument made from readily available materials: An amplified soundboard makes the vibrations of coil springs and a variety of other small and nonprecious objects audible. Thanks to a simple piezo contact microphone, the Springboard's humble constitution belies the richness of its sounds, a signature of the author's activities in live and recorded works across many art disciplines.
