GEM Optical Theremin Noise Synth Photo theremin

via this auction
"This is a 100% handmade optical theremin GEM by Magic Echo Music. It is a single square wave oscillator/tone generator, and you control the pitch of the tone by manipulating the intensity, brightness, and movement of light... You can hook up the GEM to external filters and pedals, through the 1/4" mono output jack, and there is also an additional CV input. If you have analog synths with a CV output, you can also modulate the GEM oscillator with your equipment. There is also an additional Low Frequency Oscillator (LFO) and Frequency knob which you can use to modulate the oscillator--You will get rapid tremolo effects to a very slow sequence of pulses. This feature sounds great when you hook up the GEM to a delay pedal!This auction is for the BLUE colored GEM, most closely in appearance to the blue gem on the website. The wooden sides are maple and walnut hardwoods. Each optical theremin is uniquely handmade, and there have only been 20 produced and distributed at a DIY music-art event in San Francisco."

47 Dual Angry Vintage Model D MiniMoogs

YouTube via 7thDanSound | February 17, 2011 |

"Patching up massive control from the modular to a MiniMoog to get angry sounds out of it is something of a hobby of mine. I've done it before. Not with two MiniMoogs however! Well now I have. But watching something like that is kind of boring so I made a stop motion kind of thing out of it instead. It's my first attempt but I like it. Takes a heck of a long time to make though. Enjoy!"
