@@sparkstarter I did this about 16 years ago... except i used a high voltage microwave capacitor. arcs were at least 8 inches long.

I built something just like this about 20 years ago and was damn near killed by it lol. I had no capacitor or other circuitry on mine, just the dimmer switch set to full power wired directly between line AC and the ignition coil, it could draw out 3-4 inch arcs that melted the electrode tips so it had gobs of current, and the last time I played with it (the _last_ time, I don't fool with lethal current anymore lol) two decades ago I just about electrocuted myself, I got caught on it for about five seconds going through my arms and chest when I disregarded the one hand rule, my legs kicking randomly was the only thing that saved me as I gripped the hot line in my left hand and the steel table it was sitting on with my right, AC current gives you a literal death grip, I ripped out a couple finger nails when I finally pulled away. Dumped about two quarts of used motor oil I was using as insulation and cooling all over myself and my shop too lol, the coil was in a big glass jar that went flying when I kicked away, which also luckily ripped one of the feed lines off and disabled it. Sketch stuff, I'm surprised I am still alive after my wild youth lol.

RIP, Mr. Franklin. Your experiment reminds me of ElectroBoom or PhotonicInduction without the hazard sense. Or myself prior to the age of sensibility. Still, it makes me laugh to think a consumer dimmer will repeat 20A spikes. Primary isolation at least would be sage. Spring for it & wake up another day.

Thank you Safety Troll, your self righteous advice and copious caution is strong... that dimmer has driven that coil for 20 years, built this HV box in high school and used it for many projects without incident over the years. The cap provides current limiting and galvanic isolation, don't really need a primary transformer for isolation.

I just ordered everything off Amazon! Dude thanks so much! Subscribed!

LOL i was just gonna build this same circuit , glad to see the ac cap will work

O my chat i typed too long and i cannot copy it to here. But usefull measurements you made there, and i am surprised about the hight of that currentpeaks.

Yep, I had a similar circuit set up years ago. It was hooked up to 240v. I got a jolt from it that nearly dropped me and I never used line AC as a direct power source ever again. My favourite power source since then was 48v dc a much more user friendly voltage for HV generation.

so this is in the US 120VAC one wire is hot the other is Neutral Ground, capacitor in series limits the current from mains.

The main power limiting is the 17uF cap, without that, the primary would not be happy. Regarding the open circuit voltage test, that is really bad for the secondary insulation, it will break down and eventually ruin the secondary insulation. Thanks for sharing.

great explanation

Yes, you should measure resistance from the HV terminal to both + and -, the minus will be a little bit less.

What value are those two red hv-resistors? (And another question that Comes up is: is there a third little resistor between those two 10watt-hv's, or do they use the known inputresistance from the measuringdevice to devide?)

Hey mate does any dimmer switch work?

Have you tried putting a resonant (at the input frequency) capacitor in parallel to the primary, but V rated high enough to take the secondary output ? If the secondary inductance were set so that it's resonant at a lower* harmonic, that would be cool to see.

Flowers by request only.

Why are you drawing your arc to the top of the primary winding instead of the to the common lead? You are feeding back high voltage to the coupling cap and back out onto the AC line. I saw that you have absolutely no line isolation or filtering. Your neighbors must love your RFI. I recommend a common mode choke on the input AC line as well as an isolation transformer. Your entire set up is a guaranteed lethal accident waiting to happen. I work professionally with high voltage power supplies all day and intentionally drawing an arc will get you fired. Or at least severely reprimanded. Not to mention all of the accident report paperwork!

Been playing with this setup for 30 years without incident, and I would bet I work on bigger high voltage supplies than you do... but hey, everyone has their own safety tolerance. If you don't feel comfortable with 100W of power at 25kv don't mess with it.

there is always a danger element (shock or fire) when working with any high voltage device. The capacitor serves to limit current flow through the circuit. Not sure what extra safety gain your getting by using an isolation transformer other than some EMI filtering...
