Theremin, I loved this sound as a kid and built one up in the 1970’s. Around the same time I was able to buy a Moog Synthesiser in the retail version for a song from a junk shop. I recently sold that Moog synthesiser for 25 times what I had bought it for. Who says junk is junk?
And Lost in Space used it also in several of it’s series background tracks but debatable as to whether the theme music written by John Williams had used it.
Not only can you see the theremin project in this issue of Silicon Chip, but look at the free 2009 Dick Smith catalogue, wow.
