“Hendershot Fuelless Generator” – Relay Pulsing

“Hendershot Fuelless Generator” – Relay Pulsing

For the pulse generator, I thought I’de try a relay. By using the back EMF from the relay coil, I can get high-voltage spikes to the coil.

Good idea ! But how to avoid “fried” relay ? And can you get a back EMF as high than with the Hendershot “buzzer” ? Keep going !!!
