Tiny SSTC circuit.. for TC Gun?

This familiar circuit is even smaller now and almost ready to be a tiny Tesla Coil Gun, I just need to build one more inside the enclosure. After all this testing hopefully it won't blow up the second I run it after everything is closed up. Tefatronix's original SSTC 4 circuit can also work for this but I've had better luck with this setup using the primary caps. I have this old drill I think I'm going to use as the housing. The mosfet heatsinks can be reduced in size further and the fan can sit perfectly toward the rear where vents already exist for the drill motor. The led on the drill can be used as the PWM indicator. It's all pretty perfect except the grounding will have to be worked out experimentally and I'm not sure everything would hold up without a good Earth or RF ground. 24V or less may be required for reliability.

This replication of the same circuit in my last several videos only differs in that it uses a black painted toroid for the chokes. SMD won't be necessary to fit everything but I want a small trimmer for the gate divider and smaller inductor cores. I could fit this circuit as-is in an enclosure along with a battery and boost module to make another low voltage battery SSTC and just put some trigger switch and handle on it but it would be just a little bit too big. This will just be Battery SSTC #? whatever I'm at now.

By just allowing the primary to be shifted about an inch over the arc can be changed from a straight line to slight branches. The straight line ramp looking arc allows a tiny TC Gun to be aimed at precise points like a mosquito looking to catch a quick tan. I want it to be able to light a grill also somehow.

The downside to this kind of TC gun would be the relatively small arcs that would only reach out a potential 5-6 inches to something (with swords) but it's nice to be able to run it for a while at over 10-20 BPS. For that reason I think the small drill is perfect because the battery doesn't need to be hidden and is easily rechargeable or swappable. The coil can either sit inside the housing where the motor used to be (requiring circuit to fit in the handle) or protrude some allowing the circuit to fit behind it. I guess if I wanted to take it that far have the drill trigger vary the on-time somehow. Otherwise I plan to allow for something like 5%-10% on time at 5-25 BPS or whatever I experimentally find necessary to start fires.

That's pretty much awesome bro. You are finally succeeding in converting those TC in miniature types. Later, it'll be a hand held TC Gun. Keep it up bro. If you've got a CNC, print your own casing & make it beautiful. Hat's off to you bro.

HOLY BALLS! White purple swords from such a tiny tesla😃

From my royer days I found that putting a tiny capacitor(or 2) in parallel kept the tank capacitor cool(current divider)

Very good stuff, I’ve got build this up. For a small tc gun I think this would be very good. The only thing that I think would be better is a qcwsstc.

That sure would make a nice TC gun. It's amazing how it's almost not even heating up. You can run that thing as long as you want without worrying about overheating. What's the resonant frequency of your coil and which Mosfets did you use?
