Very nice build quality! I am impressed that the plywood keeps up as an insolator for the rotary spark gap!

Hi Gregor! Thanks! This plywood is well impregnated with deck varnish. But the key is that the surface should be clean enough to prevent arcing, so it took me some time to clean it from dust after several years.

This really showcases why i love rotary gaps so much.

Excellent rotary gap build. Solid and well thought out construction

Very nice build! I am envious of all the great parts you put this together with.

Great work Daniil!

Wow! Beatutiful sparks!

love from portugal. epic build

woow the best sgtc ever.

Awesome! Great job!

Good job nice build 😊

Very nice spark good job idol

Daniil: Let me turn of the lights here, so we can see it Tesla Coil: Hol on a second let me turn it on again! Great coil man, really like it! Currently I'm obsessed with Tesla Coils and all things that make high voltage! Gonna try building my second coil in the Christmas holidays (I'm 15 years old currently going to highschool). Having said that, I too like it being at home learning about electronics much more than being in school. Great Coil!!⚡

Dear J G, thank you for comment. I would recommend you to build VTTC based on GU-81 tube. If properly designed it can easily produce sparks up to 13 inches and longer. And you will not need rare parts such as spark gap and powerful capacitors.

@@tristanlee1171 I started with vacuum tube Tesla coils for pragmatic reasons. It can produce relatively powerful sparks and you don't need very high voltage source in the primary. It doesn't need complex mechanical parts like rotary spark gap, at the same time it is very reliable comparing to solid state Tesla coils, and hard-to-break, and easy to debug.

It is not that terrifying, the real danger is not in the sparks - it is in those two grey high voltage transformers that power primary coil with 10 kV. I got sparks discharged in my hands many times, it feels like a capacitor discharge, but it cannot burn your skin much. But those 10 kV transformers can actually fry you if something goes wrong.

That is a nice coil. I wished I could build one this large. Mine is small in comparison

epic.

Cool

Залипательно, эффектно. Но не забывай, что ты создаёшь этой катушкой сильные ЭМ помехи в рандомных диапазонах частот. Которые могут и на приличный радиус распространяться, если помещение не зкранировано. Это можно приравнять к радио-хулиганству, если не хуже. Это наказуемо. Поосторожнее.

Great job! One question : is the current feeding into the caps AC or is it rectified? I didn't seem to notice a diode arrangement. Thanks!

It actually doesn’t matter at higher frequencies than the mains since it charges multiple times during the mains pulse and then multiple times in negative voltage. I hope you understand what I mean

She's a beauty, just about to start on my first one. I read that 1 metre length of arc is about 1 million volts, you look like you,ve gotten there. cheers

Thank you, I wish you success in your experiments! 1 meter per 1 mega-volt is more valid for direct current but really very much depends on the shape of the electrodes. For spark gap Tesla coil power is very important, maybe even more important than secondary voltage. To get the longest sparks you want the rate to be as high as possible so the previous sparks will keep the ionization channel heated enough for the future sparks, allowing them to be longer with the same voltage level. But for high spark rate one needs to recharge the primary capacitor faster and this requires more average power.

Wow the quality of your build is very impressive and the sound with the sparks that it's making while running are scary and fascinating at the same time hehe. I am currently building my first static spark gap tesla coil with microwave oven transformers but i dont have any equipment like osciloscope and function generator to measure the resonant frequencies and tune the tesla coil so I'am worried about the build.

@Luis-dn5mk

Funktion Generator and oscilloscope aren't that expensive. You have to buy used and analog. I also try it with Mot's (i use five of them in series to reach 10kv primary). But you have to limit them, because they get really warm quickly.

@ridefast0

Жыл бұрын

For tuning, you can use just an LED (actually two LEDs back to back) in series with the output of a cheap function generator. Works great and is very accurate for any size coil. I made a YT video about that.

Throw the 3rd switch!!

First, thank you for making such a clear and informative video about your impressive coil. You definitely need more space to test its spark length, can you go outside? I am sure you would get strong ground strikes. If your power does not trip with no variac then I suppose you don't need one, but ... not sure I would want to be in the same room for full-power starts every time! Could you say which component is limiting the power throughput, i.e. what is acting as your ballast to limit the power pulled from your wall socket?

@daniilfrolov3205

Жыл бұрын

Hi ridefast0! In this video power is mainly limited by the resistance of the high voltage transformer primary/secondary windings, there is essentially no separate ballast in this setup!

I really like the construction, very clean design. Don’t think I’ve ever heard of those “measurement transformers” before, are they pretty much small pole pigs wired in reverse to step up the voltage?

@daniilfrolov3205

3 жыл бұрын

Yes, these transformers are basically small pole pigs called NOM-10. However they are designed not for power applications, but for voltage measurement. They have calibrated voltage ratio of 100:1 and were used together with 100 V analog meter to monitor voltage up to 10 kV. They have significant over-voltage protection and really rated for much higher power than needed just for measurements, I estimate at least 2 kVA each.

great job does it wotk without a ballast at the main power to limit over current build up to the transformer

Looks like higher BPS makes larger bolts. What is the maximum?

Why do you need that much amount of kV from a transistor?

This is by far the coolest coil I've seen. Is there anywhere I can find the dimensions and specs of this coil? i.e. Turns and wire diameter on the primary and secondary, what the toroid is made of and dimensions of it etc.... This is the perfect size and is exactly what I want to build.

Hi Carson! I don't have exact dimensions, however you will need to tune coil anyway... here are approximate dimensions: secondary diameter=11cm, height=80cm, wire diameter=0.5 mm. Toroid was made out of aluminum air duct.
