Saxophone controlled DRSSTC

[profdc9]

Hello folks,

After long last, a friend and I got together and we made music using a saxophone and a Tesla coil.  The saxophone has a piezo disc contact microphone which is connected to the interrupter I designed:

https://github.com/profdc9/DRSSTC-PCB-Pack/tree/master/interrupter

which then is connected to the driver

The piezo disc is amplified by a JFET op-amp circuit powered by a 9 volt battery that connects to the interrupter sound input.   If anyone wants the details I can provide them.

Anyways, here's the videos of my friend playing the Tesla Sax:

Enjoy!

Cool integration of a analogue instrument into sparks.

Is the sound hard for the DRSSTC to reproduce since a sax is often played with overtones, pardon me for not knowing what he really played, I am close to tone-deaf

Would some filtering to the piezo circuit help on the small weird sparks and plausibel also give it some more single note play to it?

Share all the circuits you want, would like to see it. On that note, could you please update you PCB pack thread with a link to this, as your drivers are now tested, which you wrote they were not, back then.
