whats is the box under the probes?

[ConsciousFlesh]

@Travisthehead The box houses a small high voltage transformer and the high frequency inverter with modulator circuit which drives the transformer.

how i tride it with a 24v and nothing happed y

Im surprised you got anything out of the flyback running only at 100hz, you typically need about 25-30khz, im amazed :0

[ConsciousFlesh]

@Twizt3dArc The flyback runs at 18 kHz modulated with 100Hz . The ferrite core would not work with 100 Hz , and what is more important at the mains frequency the device would be too dangerous to leave the electrodes unprotected. Now all it can do is to produce a small electrical burn :)

Nice. Like the steampunk crafted look too.

I used to do this with an old Neon transformer from a outdoor sign. That had some CURRENT and the arc had what looked like an ionized flame around it.

EXCELLENT!!!

[CoolDudeClem]

Really cool. just like something out of an old sci-fi or frankenstien movie.

[SmashCOBamberg]

love your design

[peterfett]

Absolutely beautiful!!!

Gordon's ALIVE!

I like how you used a second tl494 to modulate the spark so it sounds like a 50hz buzz even though it is actually running at 100khz. Very clever.

[Ravenpulse]

it doesnt specify the resonant frequency, it says its modulated at 100Hz not Khz, therefore it sounds like 50 hz because its an octave of 100 hz

[jmartis2]

What is your modulation source?

[TallNHairyDave]

Very nice indeed!
