Electric arc lighters use a spark to create a plasma conduit between electrodes, which is then maintained by a lower voltage. The arc is then applied to a flammable substance to cause ignition, but this person has managed to modify one to play The Imperial March. “There’s an unidentified microcontroller inside this unit, which we’ll be replacing with a pin-compatible microcontroller (PIC12F1840) running our own code. The code drives the transformer using complementary PWM waveforms at ~15.6KHz to generate an arc, just like the previous microcontroller. It then modulates the waveform (and hence the arc) at audio frequencies to generate a tune without the need of a speaker/buzzer,” said PodeCoet.
