Do you know why?

So, in this configuration i still have the same problems: Hello Mads, I built this circuit with a 12v 6 amp power supply. Then I tried to connect it to a 16v 1A power supply and the power supply somehow managed to short internally lots of smoke and it heated up. July 19, at I passed with flying colors and am still enjoying this modulxted device in its own neat case.

Mads in reply to the comment you posted to me, I rlyback. October 1, at Are there pots somewhere in the ciruit?

Flyback driver #2: NE quasi-resonant – BOGIN, JR.

I am going to try making a more advanced version soon using the SGAN chip. I am using a org …. Also my power source is v ma. I was using battery of 10 — 12V to run the circuit, and in like seconds of arcs, it just stop oscillating, I was able to hear Flyback slowing down until it stopped working.

Or if you want to be absolutely sure you could make a multiplier, e.

You can salvage flyback transformers from old computer CRT monitors, virtually free! As you can see in the poto the GND line is a mess and also the signal on the drain of my transistor is oscillating. Also, use mains ground PE.

Or where did you get that idea? It was a work-in-progress. flybsck

555 Audio Modulated 20kV Flyback

When properly tuned, this topology draws between 3 to 8 amps on load, in a supply voltage range of 18 up to 2 volts, excluding the first example of my driver, which drew 3 amps and had been constructed for low power emphasis in mind. November 7, at I dont know if its the power supply im using.

Another thing it could be is you have a loose connection somewhere so I recommend soldering each connection in the circuit together so you know good contact is being made. This is a audio modulated arc generator designed for simplicity rather than reliability, its made with very few and common components. Hey I was wondering if you know whether anyone has manged to get this working with the IRF mosfet.

This is to prevent a parasitic turn-on of the FET because of Miller capacitance.

If using a resonant cap, use a quality polypropylene one, or HF ceramics with a high k VAr rating. January 7, at Mads BarnkobSorry I was having a dumb moment and I can see my mistake looking back now! Please help, what should i do??

The voltage i can turn from 0 to 32 V, and the flyback stard to make that nice sound, but no arc. Do you think that is something that would work and translate all the way to the final tesla output?

November 6, at I do have a disclaimer up above, but I think I would not want to hear you have been killed by one of my creations. Accept and hide Reject Read More. I tryend adding fpyback resonant capacitor.
