High Voltage From A Relay And A Battery  Shown With Neon Bulb #experiment  #science

Warning: high voltages.  Using inductive kickback to generate high voltage with minimal components.  Over 300 volts out from a 9 volt input.  You could put a diode and capacitor in place of the neon bulb and have a low current but high voltage source. Be careful, it bites back....
I used a battery here instead of a power supply so I don't need to worry about the inductive kickback spikes harming  the power supply.
