    How To Build A Spark Gap Tesla Coil (SGTC)

    These are the pictures! And some videos! but i think it would be better if you give me your email adress or you`d write to mine( komaromigy40@gmail.com) or to my facebook, https://www.facebook.com/gyurika.komaromi !!! I hope you can help me ( the top load fell off but it works pretty much the same :/ ill glue it back )

    in these videos i run the zvs on 12 v but i have a 24 v psu too. it works pretty much the same with that too!!!

    How To Build A Spark Gap Tesla Coil (SGTC)

    I forgot to mention that the sparks are really thin... Maybe the wires I am using are too long, thus decreasing performance?

    Where? Here on instructables? I am new here but ill try tomorrow ok?

    Wow dude, you know a LOT about tesla coils, thanks for the advice, i managed it to get it running it lights up cfl bulbs, a little bit...and neons but the sparks are like max 1cm from a wire, i am using leyden jars, cuz this is a school project and i want to prove i can make an inexpensive tesla coil, so far i have added 4 and it got better...tweaked it a little bit, in java tc it said i need 0.9cm turn spacing on the primary coil...but everybody uses theirs without turn spacing, so far have 7 turns, java tc "said" I need 6 with six it is way worse...maybe I should put some leyden jars in series too, to increase voltage of the caps... I plan on adding a 12 v motor and make a rotary spark gap...what do you think...i will make a whole bucket of vine bottle leyden jars like 10 an...see more »Wow dude, you know a LOT about tesla coils, thanks for the advice, i managed it to get it running it lights up cfl bulbs, a little bit...and neons but the sparks are like max 1cm from a wire, i am using leyden jars, cuz this is a school project and i want to prove i can make an inexpensive tesla coil, so far i have added 4 and it got better...tweaked it a little bit, in java tc it said i need 0.9cm turn spacing on the primary coil...but everybody uses theirs without turn spacing, so far have 7 turns, java tc "said" I need 6 with six it is way worse...maybe I should put some leyden jars in series too, to increase voltage of the caps... I plan on adding a 12 v motor and make a rotary spark gap...what do you think...i will make a whole bucket of vine bottle leyden jars like 10 and then work with that xD maybe that'll help :/ you said i need 1.5x or higher voltage rating of the caps as my psu, in a video the guy said these are rated for at least 30-40kV i think it was right...when i make arcs with them if i stretch the wires more than 5 cm the bottles break... Anyways thank you, you helped me a lot! (the specs of my TC : 40cm high 5cm diameter, 0.5mm enameled copper wire, aprox 730-750turns, primary adjustable i think ill make a 8-10turn on as it seems it works better with more turns..., 2mm copper wire, insulated, 12x12 aluminum globe(plastic ball wrapped in aluminum, you said i could use painted balls or glass globes, which would work better, if ill find a lightbulb pr smth rigid and big enough ill make it work! ) You are the real mvp, cheers!

    How To Build A Spark Gap Tesla Coil (SGTC)

    Hey man, i have a question i need to have a 1 to 5 aspect ratio for my secondary or not?

    But i tuned it in JavaTC but it doesnt work FTW i even tried to flip the primary and then try all over again and still doesnt work :/

    How To Build A Spark Gap Tesla Coil (SGTC)

    The zvs driver is DC, it is a zvs flyback driver, sorry for my misexpression, so could you please help me with the capacitance?

    Hi, i plan on running my sgtc with a 40-50kV zvs driver but i dont know the current and frequency of the output :( what can i do tp calculate the primary capacitors capacitance needed to run my 40cm tall 720 turns secondary with 6 turn flat primary?

  • How To Build A Simple But Powerful Flyback Driver

    Lol dude, 260's can handle double the current of the 250's those burned out after 1 min of continuous use xD anyways the heat up when they draw a lot of current from the psu, mine can give max 30A and the zvs would "eat" more if I would be able to give it more xD but if you have just a 10-15A power supply the mosfets wont heat up...on 12v 12A I can use the zvs continuousy like half an hour or more... But when I give him 24V 30A psu they heat up instantly xD... But the difference is day and night...

  • How To Build A Simple But Powerful Flyback Driver

    Of course it is ok :) it will do the same thing, I had way more capacitance and for me it worked better, everyone's flybacks differ so they need different capacitance this 0 68 is a general one which will work pretty good for all of them but if you hit the right capacitance the spark will be much thicker and hotter, at least for me with 0.68 it makes a cold, skinny spark, if I add a 2uF capacitor it makes waaaay better sparks, mostly because I use 2 flybacks in series...

    Hello, I have 2 irfp260n's on my zvs, but they are heating up so fastly, my question is, could I put 2 more in parallel with the other 2 so they would split the current...as it draws more than 30A from my 24v transformer ???

    The ZVS driver

    Hello, my zvs works perfectly with 2 irfp260n's but they heat up pretty quickly, my question is could I put 2 more of them in parallel so the zvs could deal with more current and voltage or it will just blew up everything?
