Mini coil progress
I’ve made a little progress with the mini-coil. I have two flyback drivers up and running. Each circuit fits nicely inside a 2″ ABS cup potted with silicone, now dubbed the hockey puck of DOOM.
trigatron. I’m not sure when these actual trigatrons where manufactured, but they’ve been available since the 1940s.
The trigatron acts as a very quiet, easily controlled spark gap switch. When the second flyback turns on, it closes the switch, dumping the charge in the capacitor bank across the primary of the Tesla coil.
