I'll try anyway.
I been thinking about this:
Screwdriver voltage tester works even if I jump so I must conclude
that my body surface creates capacitor with earth.
This is 220V but only 50Hz, and gives few mA for that little (neon?) light.
So what happens at higher frequency ; as for voltage, come to think about it, I can go as high as 220V
or even use microwave oven step up transformer ?
I want to use square wave only because it is easy to build, and later maybe something better.
Here is a newbie question: Why do they (sometimes) call ferrite coil (in input resonant circuit) antenna ?
