Theremin Coils
Q: “Hey charlie, I’d like to build a theremin. Where
do you get those gorgeous gigantic coils?”
A: ” I make them.”
Probably the most intimidating part of building a vacuum tube theremin (or Tesla coil) is the prospect of making large custom inductor coils. Just the thought of winding gossamer-thin magnet wire thousands of turns by hand is enough to scare away most amateur builders. While winding large coils isn’t necessarily difficult, making the end result look so pretty is.
For over five years (sheesh, already?!) I’ve been hand-winding large inductors for other builders and enthusiasts. Theremins, Tesla coils, or otherwise – if you can get me the specifications ( diameter, wire gauge, and # of turns) I can wind it.
