The Springboard is an electroacoustic coil spring instrument I built in 1994 to explore unusual sounds that can be made electronically and at the same time, haptically (by hand) and inexpensively than had been possible with tapes and synthesizers.
I have two articles about the Springboard published in Leonardo Music Journal, Issue 17 and eContact!
This series of videos on the Gearwire site is one in a series demonstrating the Springboard's construction and sounds. The videos were made for Gearwire by Gretchen Hasse and are also on my YouTube channel embedded here below:
