RS Illusion Theremin
  The RS Illusion M3 operates around 850 kHz.



Buy the PC Board & Etchant first, if you can't etch a good circuit board you don't need the parts!

The silkscreen of the component graphics might not iron onto the Radio Shack board effectively.
If you can buy a one sided copper epoxy board from another store do it!
