Dear, Most Knowledgable, Netters: Have any of you built a Theremin or capacitive proximity sensor? I want to make a proximity sensor with a range of about 3 or 4 feet. Any hints, tips? Circuits, even? Any suggestions as to the most appropriate frequency? I suspect that it would be the resonant frequency of the human body - does anyone know what that might be? Kilothanks, Doug. -- Doug Collinge School of Music, University of Victoria, PO Box 1700, Victoria, B.C., Canada, V8W 2Y2 decvax!nrl-css!uvicctr!collinge decvax!uw-beaver!uvicctr!collinge ubc-vision!uvicctr!collinge

I've built theremins and capacitive switches in the past. You'll find construction projects for both in Popular Electronics ca. 1967. I think the theremin project was in the November '67 issue, and the capacitive switch was within the next year.
