The TeslaPhonic Organ V2 project was such a hit, I've developed a 4 channel version using dual ATmega162 micros. I'll post a new project entry for it shortly.

Here's a link to a video of two channels playing a MIDI file:

Here's a link to a video of a single channel playing from a bass guitar:

Cool, not sure how it works but anything with Tesla coils gets an A+,

Amazing project. Honestly, if I wasn't so afraid of becoming a magic lightning rod to a Tesla coil, I'd build it. Well, that and I don't think my dad would approve!

How is the sound generated? I assume the discharge is modulated by your controller in response to MIDI/wave input. I haven't downloaded the full package yet - too late tonight. How are the HV/LV sections isolated from one another?

I'd love to see a video of it playing the Axel Foley (Beverly Hills Cop) Theme ;). Well done.

Make Atmel Studio better with my free extensions. Open source and feedback welcome!

Basically FM modulation. The Tesla coil will spark when it's excited at it's resonance frequency. If you modulate this frequency in the audio band, you can hear it. The IGBT driver ICs have an enable pin that I use to modulate the resonance frequency based on what MIDI note I get, or in the case of the guitar, an amplified, clipped, and squared analog audio signal.

I'll look into that.

How smart is that! Way cool project! Please post your other songs here too and maybe start with a shot with the light on showing off how you made your board too.
Thanks for the post.
Cheers,
John

I am utterly impressed with your project! What is the power supply for the primary coil? Can you post the specs on the coils? :)

I'm working on a new web page for this project with more photos, schematics and specs, I'll post the link when I'm done.
