Fun with an electric fly swatter/zapper racket, including taking it apart to show at how it works, and demonstrating it powering a Franklin’s bell and making sparks. Turns out that it’s a joule thief/blocking oscillator circuit.

Hi, I f you could help,i’m looking for a circuit that uses a high frequency oscillator in a pair of conductors that will trigger an alarm when disturbing the frequency by passing (a human) close by. Can you help? Regards,Herman
