Lolly from Germany is a creator of one of the Tesla coils that was featured in the Musical Tesla Coil Collection article last week. Lolly has now created a video that walks through the technology he used to build his device.
“Overview and demonstration of my SSTC Setup. The RF is generated with a Class-E MOSFET stage with controllable Frequency.
The sound is modulated on the gate signal of the MOSFET via PWM. The sound is then emitted by the arc itself. Excitation and PWM Frequencies are set with DDS generators controlled via a Microcontroller board with USB interface.”
