Electric protection 1930's style
My high school geometry teacher told us about a rig he build as a teenager.
He used a tilt switch from a pinball machine as trigger, and a "spark coil" from a Model T (a vibrator and high voltage transformer package). Ground was by a chain dragging on the road connected to the coil minus , and the whole body was hot, insulated by the tires.
If someone bumped the car or started to climb in they got bit good.It was comparable to an electric fence.
Then one day a fellow who had been bit stopped by while our genius was washing the car, reached in, and flipped the secret switch to turn on the rig.
Bare wet feet and wet hands made for an exceptionally low loss path, and theinventor was flung unconscious to the ground. Lucky he didn't collapse onto the car.
Biting the hand that feeds IT
