[sdiy] Add a theremin mod to an LFO....

[mathieu.vallet]

HI, 

 

I built the Ray's Cool New LFO at
http://www.musicfromouterspace.com/analogsynth/coolnewlfo.html.

I'd like to add an antenna to control the LFO like a Theremin.

 

Is it possible?

Which circuit do I have to add??

 

I had added 2 copper plates to the LFO, one for GROUND and the other to
control the LFO. IT work but I have to touch the copper plate for ground
with a Hand and touch the other copper plate with the other hand. 

 

Is it possible to have more sensibility for the copper plate which controls
LFO, so that I have not to oblige to touch the copper. 

Add a transistor??? A circuit??

 

Thanks if you help me

bye
