Re: [TCML] Tesla Gun
The foot plates are already wired into the electronics ground, i didnt
state that before, though. The current that flows in my body is due
mutual capacitance between the tesla coil and my body. There is no
way around it unless i wear a full conductive suit/shield between me
and the coil. The foot plates will just help reduce my peak potential
i think by connecting me to some impedance to "ground", but i think
that impedance is still pretty large compared to my body's capacitance
at 400khz. You can think of me as a counterpoise if that helps make
sense of it.
I guess i could have some sort of metal apron that would eat up most
of the capacitance to the coil. I'll have to do something to protect
myself if i make a habit of using this thing

Allowing you to still be mobile =)
