#coillabs hey buddy I suggest cutting of the rest of the pins from the flyback and pouring melted wax on the transformer pin section to isolate it better just remember to keep wax out of the cathode pin. I noticed a boost in my flyback's arcs cause before I wasn't able to burn anything and arc just passed from the side of the object but After waxxing it the arc was much more powerful

Yeah I get flashover on the pins if I turn the voltage up too high, for sure. I'll definitely consider doing something like that if I need to drive these things at higher power in the future. Thanks for the suggestion!

I love flybacks, I've got one set up right now running off a generic ebay multifunction driver and powered by a 30 volt Lipo, I can draw 4 inch white arcs with it. It's almost too much for my Marx generator, it tends to flash over between one of the spark gaps and start an arc lol. I just need to redesign the generator with a little more space between everything now...

Nice! At some point I want to build a much beefier ZVS driver and get a big ferrite core and wind my own flyback that can handle some serious power and make some huge arcs

@@CoilLabs We have similar goals then😉. That would be _really_ cool to build an upscale flyback driver, makes my toes tingle just thinking about it lol.

Hell yes

Muito bom gostei muito da qualidade do seus vídeos continue assim 👏 Pena que não entendo nada de inglês

The one I made a few months back crates very feathery purple arcs its not a zvs driver type but a 2N3775 type transistor how can I make it better? Any idea?

There are a lot of different circuits for driving flyback transformers. I'm guessing the circuit you're using is the single transistor (BJT, specifically) circuit, using a feedback winding to trigger the switching? This is a great first step to learn how to work with flybacks, but if you want to want to take the next step, I would look into building a 555 timer based flyback driver. You'll want a higher power transistor, like a power MOSFET, to get better performance though. Just Google "555 flyback driver" and you'll find a bunch of great resources. Once you've mastered that, then I'd take a look into the ZVS driver. That's the best way I've seen to get the most power out of a flyback transformer.

@@CoilLabs i got a question if I use two of the same 2N3775( the large shiny flat metal transistors)transistors in parallel or in series might that boost my circuit in any way?

2N3775 is 60V collector-emitter and only 1A max collector current from what I read. You might get some improvement using 2 in parallel to handle more current, but I doubt the bump from 1A to 2A with that circuit topology will be a dramatic improvement. I don't know what input voltage you're using either. When I say power MOSFET, I'm talking about something like an IRFP250N or better. 200V, 30A. That's way overkill unless you're willing to upgrade your circuit topology and also supply it with enough input power though. If you're blowing FETs with a circuit like this, then I'd guess you aren't using FETs with the right ratings.
