I've been making Theremins for years using them mostly in my installations to control other work. The first Theremin that I ever made was from converted old valve radio when I was a kid. In the early 1970's inspired by Roger Spears electronic leg I made several strange versions, one using a rotating metal teapot and another with an 1930's ozone making machine.
From time to time, I get the urge to make a Theremin. They are always vacuum tube designs. Here, I present some pieces selected from the late 1980's to late 90's.
