These Theremins I create are based 
on the Lumens Photo Theremin and 
have been around for many years. 
To operate simply flip the switch to
ON, plug into some effects if you'd
like and output to amp, place under 
or around some lighting and You're 
ready to start waving your hand 
around from side to side and up and
down to change the pitch, drastically
ranging thru several pitches from 
very high to super low. The knob 
allows you to dial in the depth of 
pitch you desire. Each one is 
unique in that they are all mounted
in old toys, etc allowing diffferent
and MOD one of a kind creations. They
may be played in total darkness using
a flashlight, remote, any light source.
I can build a theremin and mount it in
your favorite toy, robot, orb,etc for
$45 plus return postage.
