I used to love reading Radio-Electronics and Popular Electronics magazines ... [they] were a great introduction to the mysterious workings of the electron. ... In 1965, the first project I built from those magazines was a theremin. ... I discovered that having both a theremin and a guitar amplifier let me do some interesting experiments. ... The game was to start the theremin at DC, meaning no sound, and gradually walk the pitch up until the furnace was rumbling and buzzing like the nuclear reactor in the movie The China Syndrome. From upstairs, this sounded as though the basement was attempting to rise up through the floor. Subscription (IEEE Computer Society membership) is required.
