Everything in this build was reclaimed from items that were broken where I work.
This latest instrument is an evolution of The Dronemachine I made a few months back. It uses the outer core of an electric fan motor as a pickup, a cassette player motor drives a piece of string which causes the musical strings to vibrate. The wooden peg looking things are actually part of the action in a Grand Piano, when you press down on the end, they raise the washers and shorten the length of the wire. It’s a pretty simple concept but it’s taken me ages to figure out how to put it into action!
