Kubby TV #61: Monster Tesla Coils from old HID ballasts

Everyone has switched to electronic ballasts, but those old clunky ballasts still work. Each of those ballasts is a Tesla Coil, designed to step up the frequency and voltage. So why not do something to light up the neighborhood? Make sure to add an old amp to drive the monster then mount the discharge heads on the roof. And don’t forget your earplugs, because all those gigavolts are LOUD.
