Small DC Tesla Coil 1

[@777cc777]

Thank you for giving us all the opportunity to see this. Your equipment is clearly very well crafted. the important HV safety note at the start is also very commendable. Thanks again for clear explanations and great posting!

[@raserapps8230]

his mouth dont move when he talks - no offense but I can't help being reminded of Men in Black - the alien that crash lands and uses the farm blokes skin to conceal himself. Joking aside, this man is a genius, knows his stuff. I looked at DC powering - very low voltage, no arcs but I still got all of the strange effects - light bulbs lighting up e.t.c. This little Tesla coil is a MONSTER!

[@ghosttroop]

Great work RogerInOhio! Detailed; ingenious; impressive. Thank you kindly for sharing your work. Not only are you a genius but you're a legend too.

[@bendavisishott]

Roger You are hardcore awesome, that's probably the nicest baby tesla coil ever! I wish I could see it in real life! Ben

[@zachtankersley]

Although I have quite a bit of experience, and have even built my own Van De Graaff generator, I'm still only in high school and these things are extremely complicated and hard to understand, at least in all other descriptions and diagrams. These videos have helped me a lot in understanding and learning, so..... PLEASE DON'T STOP MAKING THESE VIDEOS! I don't expect it but any help on building mine would be greatly appreciated.

[@fubar247]

Very informative....that cricket during some of the presentation is relentless, lol

[@teslasintern]

Good job Roger, I'd be interested in knowing the difference in the AC power draw between the DC and NST coil setups. I'd assume that the DC draws more current from the wall (because the brighter sparks). Keep posting videos.

[@igotapochahontas]

hey thanx 4 the shimfo! thats all i needed to know, im still trying to comprehend all the technical differences of ac/dc. that actually answered my question, thanx again

[@triggerhappy77707]

hello roger.i have made a new tesla coil thanks to your knowledge..i get a 2 inch spark with 2kv and i have 10kv on the way so im hoping that one day i can get the mot's and the resistors and use a schematic similar to yours.thanks again roger!

[@benjstrong]

I really like your videos. I would love to learn more from you.

[@MorbidAngelification]

wow man, you would make Tesla himself proud.

[@cantonboy77]

I also made a Van de Graaf generator in middle school and high school. I took a state science competition with it in 8th grade. Any questions, feel free to ask. :-)

[@bluetrilobite]

wow. the dc setup makes such a nice spark! not so much for the noise though. still cool

[@Milner62]

think of a automotive igniton coil its same basic principle as a tesla coil. You have primary windings in the coil that is provided voltage to create a magnetic field then you have either breaker point or electronic where the circuit is broken when that happens the collapsing magnetic field causes voltage to be formed in the iron core and create a spark ranging between 40,000 Volts to 80,000 Volts depending on the ignition system. Car system is a 12 Volt DC electrical system.

[@TheEvilCommenter]

Zap that freaking cricket with your tesla coil

[@triggerhappy77707]

a 40 turn secondary. I could have had longer if the resonant frequency was lowered with a topload. I know this from experimentation. My 300 something turn secondary with a resonant frequency of around 1.4mhz, lowered to around 600khz with topload, got a 9 inch spark after tuning, and the secondary was only 6 inches. This was a vacuum tube tesla coil, but this does not matter. It is all the same principal. Oh,and the primary was about 25 turns, so if the ratio mattered, I would have a small spark

[@triggerhappy77707]

hello Roger. i love all the stuff you do..you have really inspired me to keep doing high voltage research and projects.anyway,would you happen to have a good way for a poor 14-year-old to get a high voltage power source?i have been testing my tesla coils on 600volts ....also i would like if you could give me a schematic for a multiplying circuit for an MOT including cap and diode specs.your biggest fan,Matthew Abshier..

[@speeddemon467]

Very, very cool stuff.

[@gizmoguyar]

Am I correct in saying that by changing the resistance of the filter choke, one could change the interrupt rate of the tesla coil? It seems like there'd be a way to play music, like with a solid state tesla coil? Also, it then seems like (by slowing the interrupt rate) one could use a smaller power supply that would take longer to charge the capacitor and therefore produce longer sparks with less power? any thoughts?

[@KyleMakeStuff]

I love it roger great job :)

[@TeraVoltLabs]

You've been hit with plasma a few times, haven't you?

[@triggerhappy77707]

No matter if you use AC or DC input, the secondary will always be oscillating. Think about solid state. I guess the oscillations would be called ringdown. Humz. Once the spark gap fires, oscillations continue through the spark gap for the few ms (i guess it would be in the ms range?) between the tank capacitor and the primary, of course still coupled into the secondary. Goes to show how little i know XD

[@Tab54o]

Whoa are you using glass mike caps int that coil?

[@triggerhappy77707]

Not really, a tesla coil is made to operate at resonance. Ignition coil frequency always veries with the revolutions of the engine. Also, if voltage is built in the iron core, you will have alot of loss as eddy currents. The core simply becomes magnetized, when the primary voltage falls to zero, the field collapses which is the coupled into the secondary, and a some back into the primary. If you have a 6 cylinder engine, the iggy fires 300 times at 3000 RPM. 8 cyl, 400 times a second.

[@JayMaxTay]

Very nicely presented video

[@KrimReefa]

COol. By doing this you will save money on your power bill ? and the sparks coming off will not effect humans ?

[@Milner62]

I said same basic principle I didntsay a ignition coil and the tesla coil are the same. You basically said what I said just in more technical terms which I avoided so more people could understand. I said the collapsing field causes voltage to form in the iron core and spark to the plug. The voltage of the spark is dependent on how the coil is wound.

[@newtonianbarf]

ebay, or a transformer shop ( pole pigs) I would recomend you get a neon sign transformer from ebay first because they're relatively safe and cheap. they're also already inductively ballaced, unlike most other xfrmrs. goo luck. ( how the hell are you doing tesla coil stuff with 600 volts? Solid state?)

[@Solidus1Syndicate]

Nice video ;) I'm going to make one with a rectified flyback transformer of about12-15kV.

[@Milner62]

I know your not I am just saying theres some confusion going on. I am just saying a ignition coil and this are simmilar though because lets face it both gives off a spark and they both have windings regardless if they create the spark the same way or not is all i am saying. I fully know a tesla coil is way different but their technically using the same principle just getting the spark in differentways. Sort of like breaker points to charge and discharge the ignition coil down to magnetic.

[@bauerb2]

i got almost the same results (just a little less) using a halfwave rectified flyback transformer. anyways, 2 mots to that little thing??? lol nice one keep it up

[@triggerhappy77707]

well i have no got a small 1 or 2 ma 9000volt (estimated)with a large bowl cover with aluminum tape and a 6inch by about 8 inch jar in parallel for the tank cap and i can get a 1 inch spark

[@Epanouissement]

The real sheldon cooper

[@Milner62]

Hate to say this but your getting ahead of yourself. I am talking about a ignition coi when I said that so you dont have to go all technical on how a tesla coil doesnt have this or that. I was saying the spark voltage is dependent on the turns. Thats the only way on a coil how to get high voltage out of the secondary circuit while saturating the primary circuit with low voltage.

[@anonymousanonymous9991]

He did an incredible job, this video was for many more people than just you. I've never built a DC Tesla Coil and I wanted a baseline example of how someone else did it. I was not disappointed.

[@Ivan.Wright]

he talks with his mouth shut . hahaha

[@triggerhappy77707]

Thats what i am saying though, the voltage output is independent on the turns ratio. Not ratio that matters, resonant rise. Just to reassure you, i am not trying to be mean :P. I am simply trying to present my thoughts. Need no enemy's :P

[@triggerhappy77707]

But that is not true :D. Tesla coils are independent of secondary turns. The ratio makes no difference. It is all dependent on resonant rise. Why do you think a out of tune tesla coil produces no spark? The resonant rise requires the resonator and primary to both be running at the resonant frequency. Ignition coils run at many different freq's. You do not have to run any where near the resonant frequency of the core or anything, and you still get high votlage out. I have had 1 inch sparks with

[@DerOrk]

Is it possible to abuse a Coil for zapping stingy Insects?

[@igotapochahontas]

at the risk of sounding like a complete ignoramus, how did u get a transformer to work on dc? i thought electricity had to alternate to transfer power to the secondary.

[@jdsilver86]

you tryin to get in this guys pants?

[@huddassc]

damn that cricket!

[@TheNuclearWatermelon]

NICE!

[@GilaSpaceleigh]

OMG I'm from chillicothe!

squealy :)

[@KeatonReckard]

you need a girlfriend.

[@smh9902]

Why, so she can mess this guys life up? This guy seems pretty happy as it is (just look at that smile!) so no need risking everything for some selfish broad.
