Tesla Coil Show Controller – Analog Audio Interrupter and Test (Part 6 of 8)

In this video I install and test the analog audio interrupter and gives a walk-through on how I am using it. All schematics for the circuits and PCB layouts are available at the project thread: Project thread: https://highvoltageforum.net/index.php?topic=1417.0



The analog interrupter audio input is quite simple and build up around a single LM339 op-amp. It has a toggle switch between normal BPS interrupter output and the op-amp output. The potentiometer is a frequency bandwidth limiter setting somewhere between allowing a maximum frequency from 100 up to 500 Hz. Overall on-time is still limited by the normal potentiometer for on-time adjustment.

The amount of wires is getting out of control. I am however very happy about the color-coded wires, as its still easy to follow single wires back to its origin.

I am building a Tesla coil show controller that can control up to 6 Tesla coils at once. It will feature individual interrupters, touch screen controlled MIDI interrupter, safety features to ensure a safe method of working with the Tesla coils before a show, under a show and after a show. It will all be housed in a transportable 19″ rack mount flight case for ease of transportation and to protect the electronics. The 6 channel MIDI interrupter is the feature rich Syntherrupter made by Max Zuidberg.
