A homebrew perfboard with four huge HV capacitors, some large HV power resistors, an air-core inductor coil, and a TO-220 thyristor at the center. At the left, there's a big red button, galvanic isolated from the HV power domain, for triggering the surge. At the leftmost side is a ready-mode HV power supply module.
