Tesla coils are so much fun. I built one in the mid-1960s when I was in the seventh grade. I fed it with an Armstrong oscillator using a 6V6 vacuum tube. The output coil was an old television high-voltage transformer of the kind they used before there were flybacks. It was just an air-core step-up transformer that had a third winding that was the tickler for the Armstrong circuit. I think I got about 30 kV out of it. I also acquired an old oil burner transformer that put out about 10 kV. I was going to use it to build a larger Tesla coil but my father put the kibosh on that, so I mostly just used it to set things on fire. Sometimes I'm amazed that I survived my childhood.

This was the only video I could find that described the difference between the Tesla and the Slayer coil adequately,,,Thanks

Best explanation of Tesla coil... Reminds me of the burning bush

More Tesla coil info please. Thanks for all your great videos!

wonderful explanation, thank you !

I like these neat Radio Shake projects. Wish they were still around like in the 80s. growing up

4:47 I think you got this wrong. The transformer doesn't drive the spark gap, the capacitor does when it charges to a high enough voltage. The voltage charges the capacitor. When the capacitor charges to a high enough voltage, it then discharges from the spark gap which dumps all the charge through the inductor. That is what drives the secondary coil on the tower.

Great to see that Avasva has new instructions to save my money and energy to build it.

Nice little project. BTW, That new lens is much better. The first half from the Zenith retro was kinda blurry.

hey , so i am student and im doing ths project as my lissence degree , and i like ur job thank you so much , just can i ask you one question that i coudnl't find informations about that , as student the therory is mroe importante so i need to know or calculate the current running throw the transistor Ic or Ib because when the seocndary coil is vacuum witch means the current will be higher ( iknow there is a C parasite with the ground ) so any idea for how should i know the current in the primary at least approximate. thank you !

Does the torus need to be a specific size or would the coil throw out atleast a certain amount of spark irrespective of torus size?

15Ghz single pulse square wave energy transfer (one pulse in every 2 for 5-15Ghz) KZfaqNinjaExpand Thank you very much for your posted video . Difference of a length of wire by 2.3 cm compaired to the 3cm version of the antena for 4 nano newtons of force to 4KN. (amps to newtons for up to 200 columbs) microwave absorbing diode

referring to 5:08, when the gap sparks the 6kV transformer has the secondary in short circuit. Is not this to be avoid, always?

Thanks verry much sir

Can we use dc motor copper wire for the secondary coil of tesla coil?

Short Video = Almost Half An Hour ;)

Interesting little project. Just a thought, as it produces RF, does it completely swamp the broadcast band with noise?

I may try this kit, looks interesting. I'm curious how much voltage is being generated from the secondary?

from which 12 physics chapter this model is made

I suppose it would cause unwanted RF interference? Is that why your former neighbors were unhappy?

Are the primary and secondary coils wound in the same direction

no you should just do what i did its 14.1v input to this system. motor speed controller, 8-60v adjustable voltage booster feeding a 1.2kw zvs driver, driving a flyback from a 56in box tv. yup the fly back in toughs are able to get 100kv with 6 turns as a three pin primary. then that will have a safety spark gap going to the older style Tesla circuit. but with one big difference the coils its self will be 2 on the primary and 102 on the secondary with 1in diameter 1foot tall and the primary is a 2in diameter with 1in spacing 3in tall its a 51x multiplier tesla coil

could this be converted into a super tiny jacob's ladder?

Can you explain how this works when the AC mains are changing polarity? It is described as if you are talking DC. I can't find a good explanation of how AC changes the spark gap action.

What happens when you put L1 across the middle of L2? :) Check what happens with Amps. Let us know :)

Thank you! But tell me why the capacitor discharge through the primary coil ? It can also discharge through the secondary coil of the transformer. Plz!help me , i have a dream to make a tesla coil. Plz! Use easy english to answer me ,beacuse i am indian. I don't know english very well. But plz plz plz plz plz plz help me, do not break my dream.

why we must take a spark gap? what'll happend ,if i take a high resistance inspite of spark gap?

Best idea yet for the Infrastructure🙏.✌️🤘✋😎😎😎😎🤓👽👽👉👈👇👆☝️🖕👌🙏

Can it charge your cellphone wireless?

with a topload on ot, i can interfer with my TV (5m away)

thats why u use tungsten for your gap'''' its the best to use'' and the larger the tungsten is the more the amplification it produces'

Isn't it interesting how the schematic for a spark gap Tesla coil is exactly the same as a spark gap transmitter from the same period? I'm not saying one copied the other but coils, capacitors and spark gaps were all they had to work with back then. Tesla didn't invent the spark gap transmitter but was probably the biggest con artist of his time and modified it for his own use by adding the resonant step up coil on the output instead of connecting to an antenna.

I'm building a bigger version of the Tesla coil

Что происходит по началу демонстрировал схему на искровом разряднике в итоге показал резонансную игрушку с алиэкспрес зачем людей разводишь ?!.

"short"

if tried my ass off to make tesla coils... and i've tried ALL the different schematics ive find online.. and this one is one of those that do not work... and i don't know why... i get a spark over my spark gap of 3mm. (if you take 3mil volts per meter break down voltage to millimeter) u will get 3mm*3000=9000volts across my spark gap... and no matter WHAT i repeat NO MATTER WHAT capacitor i put in there in series AFTER my gap to primary windings, do i get higher outputs... I don't even get a spark from tesla coil to my finger at even dead bolt range, against the coil itself... so how you people do this shit is beyond me....tuned my spark gap with each different capacitor i put in... NOTHING works... the only way my tesla coil amplifies my voltage is if i put a full bridge rectifier in parallel with the capacitor in series with the spark gap in series with the primary.... these spark gap capacitor driven tesla coils don't do shit for me....... so how you people do it i dont know. please help me.
