[sdiy] Shielding around Theremin RF Oscillators

[Paul Perry]

I find thin brass sheet the best thing for shielding.
Very easy to solder & more rigid than copper.
Easy to find, all hobbyist shops have it.
And, yes, you will want to ground it.
All I can say about RF theremins, is that building one is
likely to be a very educational experience.
