  • This thing is definitely not 2 MHz!!!!!!

  • lol did that hurt "OW,OW,OOWWW,OW.

  • I've managed to get longer sparks from car ignition coil based TC. It's way out of tune...

  • use a smaller ball

  • coukd u put a glass globe around it and make a plasma ball

  • does that hurt -_0 like does the electricity hurt bad when you touch it what does it feel like

  • lol, Ow, oww...ow.

  • loll! "Ow, ow, ow (I'm gunna keep doin it)"

  • hay i was wondering it you could use a the cap from a disable can

  • how dos that not kill you

  • @kkkkorman no amps

  • How do you measure the frequency?

  • u HAD to touch it do u... btw can make vid instructions on how to make this?

  • you idiot

    

  • Why do you not die when touhing those sparks

    Shouldnt it kill you instant??

  • Good video ! More on "Tesla and cold electricity" by HorizonDelta

  • sssssshhhhhhssssssspark gap lol

  • Feafst koa greissane ned baun? ^^

  • hey nice vid... Where did you learn how to make this?.. I'm really interested in making one of these. Do you think u can help me out with websites or anything

  • wow really nice.

  • A normal Induction Coil of a Car makes longer sparks than this Tesla Coil^^

    Sry for bad English, i´m German

  • get a smoother top lode, possebly a triode for the streamers to shoot off allways

  • is it possible to make the same size that can be touched with the fingers with a flyback?

  • question in this experiment body dose acts as a positive charge or negative?

  • @supperstorm  The body acts as a ground. Since the current is AC, it changes it's polarity many times a second. The body acts as a zero, which creates potential difference with any negative OR positive charge. Therefore, the body is both.

  • *sigh*.. Here's a tip for you, when you want to conduct electricity through your hands you should use your right hand so the current misses your heart. Have a nice life.

  • "Ow, Ow, Ow" lol!!

  • Why isn't it killing you!

  • Holy cow! You are a stud.

  • your fingers were purple, stop touching your tesla coil!

  • please make a how-to video or send me a plan please very nice 5*

  • ouch

  • hey if i were you i would go to CVS and pick up some zinc or something because touching it (though that was a small coil) still might have effected your immune system. So go get some zinc to make up for that.

  • @guydie5 How exactly would that have effected his immune system? Im not trying saying it wouldn't necessarily i really just dont know.

  • I dont really know either its just what everyone says and why alot of schools dont allow tesla coils.

  • ow ow that hurt xD

  • can u make a video on how to make it

  • Doesn't it cause damage to your nervous system to touch it?

  • @6418978876

    i think it doesn't cause much damage ...

    The coil has 30.000 volts but little amps, so it cuases a bit pain, but there are many nerves, and the skin is a resistor too. but I couldn't build a tesla coil anyway^^

  • "ow ow yeh ow"

    lol

  • lol... ow! ow! ow! xD btw: cool video

  • Great job doing it on the cheap!

  • If I had my hands on that, I'd turn it into a super weapon.

  • lol

  • stop cooking your self

  • put ur junk on it!

  • hahahha lol

  • NOOO i took you suggestion but i did it on a bigger tesla.... NOW MY MYSTERY MACHINES ARE BROKEN. asshole!

  • post a video how to make it :)

  • make it bigger to zap people lol

  • Put a glass globe around it if you want to put your fingers on it!!!!! SILLY!!!!!

  • 1:14 - ... au.. au.. au.. ^^

  • 1 star cus of yer gey voice

  • 1:19 mortal kombat - Raiden

  • hey it's pretty cool:D how is your high voltage capacitor built? using salt water?

  • Hey man...I have very small tesla coil...10 cm high...and I use 8,4V (3A) acu....and I have sparks 10 cm..

  • For some reason this reminded me when I was a kid, and when I built Tesla coils in Red Alert my little brother always called them as "Angry Xmas trees"

    But anyway, nice vid. Gonna give it 5 stars. :)

  • Haha thats what my sister thought they were. Well, electric trees.. :p

  • You know its funny, Red Alert is what first got me interested in Tesla Coils also. hehe

  • Are we talking about the video game Red Alert? Wtf?

  • you know it!

  • Cute TC.

    Hey have you ever experienced TC distrupting your household alarm?

    I totalled mine burglar alarm. I was operating mine TC upstair room right underneath the alarm control. It went off had to replace a new circuit board.

  • Did you put a line filter on it. Mine made the phones ring when i powered it on.

  • Yeah, I filtered the mains with parallel capacitors. What I reckon happened was that I the primary coil was directly above the alarm control thus setting it off resulting the damage.

  • Well, when I was doing a HV demo at a school, I think I may have set off the school alarm lol. I'm not 100% sure if it was my fault, but there's a high probability that it was.

  • Looks like it could use a good tuning. I make coils with 12,000 volt NST's that produce 23 inch sparks. Keep in mind that my secondary is only 1.75 inch by 17 inch acrylic tube.

  • What's the current on your transformer?

    Oh, and at the time of the video, I didn't realize that my transformer was supposed to run off of 220, so I was only getting half the output of a 12/30 nst.

  • THey are 12,000 volt 30 ma Franceformer NST's. I use MMC polypropylene capacitors with bleeder resistors, an 8 gap copper tube spark gap and a flat wound copper wire primary.

  • If you need more current from your NST, depot it and remove some of the current limiting shims, but not too many or else you could pop your breaker:^) Go to Ebay and get yourself some MMC polyprop caps. Change that spark gap to some copper tubes laid side by side. That NST could get you some nice 20+ inch sparks with some some serious reworking. Happy coiling

  • ssss-ssss-ssss-sssspark gap :P

  • Lol I had a brain fart and couldn't think of the word!

  • sss-ssss-sssspark gap :P

  • what are the tube measurmenst?

    and how manny turns?

  • That is not a mini tesla coil since u used a neon sign transformer which is capable for building a big one. All parts should be small like using a TV flyback as high voltage transformer.thats mini!

  • pretty cool

  • hah nice coil man.

  • whaahah

  • What if you will build tesla coil like in RA, In natural size and charge from electric power station? ;)

  • Nice but small

  • Nice coil ;) come to me.

  • lol emo shoking your self

    jk

    nice tesla thing must be hard to make

  • it is only emo if he said it hurts so good

  • This is so cool. Nice project! But how do I make one?

  • Ouch. I would be careful with this device as basically a step up transformer. Color TV runs at about 15,625 Khz.

    and a few thousand volts at this frequency at other parts of TV and if you touch that it burns holes in your hands and can cause a severe shock. Make sure your current is limited. remember the old saying its the volts that jolts. But its the mills that kills. "Mills being Milliamps"

    So be careful when experimenting otherwise if you do it wrong you will get fried.

  • Lol *touch* ow ow ow ow *touch* ow ow ow dam!

  • thats not a tesla coil its a static electricity thingy

  • Wrong. What you're thinking of is a van de graff generator. They don't have any coils or transformers or spark gaps of any sort. Just a vertical moving belt, a wire brush pickup at the top, and 1 conductive roller and 1 non-conductive roller.

    Whats coming off the top of the sphere in this video is around 30kV of 2MHz alternating current. Static electricity is DC

  • You said 60kV in the description, but 30kV looks closer to the truth.

  • Thanks, video description updated. I'm not very accurate in judging voltage-spark length ratio.

  • Can somebody tell me how To make a little tesla coil like this one?

  • With lots of time and research :)

    Google is your friend. Use it liberally.

  • you are indeed very helpful..doesn't even point the other dude in a good direction

  • I wish i could make one :'(

  • I sent you a message with some links to some good sites.

  • shouldnt the brine solution be on the inside of the jar?

  • It is. As well as on the outside. The bottle had lettering on the glass and foil would have left too much air, so I used the saltwater on the outside as well.

  • cool!

  • WOW COOL whare did u get the neon sign transformer??

  • I got it on Ebay for something like $30.

  • lightning is not made from something entering our atmosphere. it is caused by static charge build up in thunderclouds from the water droplets moving around in the air. once the charge builds, it discharges as a big spark, which is the lightning.

  • why you doesn´t become a shock?

  • because of the high frequencies, if it was frequencies like from mains voltage which is 50-60hz it would of hurt like hell and possibly killed him.

  • @vallalle

    what?

  • OMG!!!DUDE!!!THIS IS SO COOL*****But so Deadly!lol!Dude pyrotechnics is safer!ROFL!

  • *spark* oww

    *spark* oww

    lol.

    Nice little setup there.

  • hope you make it to 12!

  • is ur capacitor made in saltwater....

  • Yep. A mason jar inside an 1 gallon apple juice bottle with the top cut off. On the top I floated motor oil to minimize corona.

  • lol isn't that how you make those globes that have bolts of electricity shooting at glass so you cant get shocked? so they were Tesla coils i learned something lol and get some gloves your finer tips look like fricken KFC chicken

  • lol

  • HAHAHHAHAHAHAHAHAHAHAHAHA

  • lol i would put my whole hand above the ball so then i will conduct electricity like cartman off the south park movie and start killing people with lmao

  • is that toirod made from a tennis ball & tin foil?

  • Yup!! Well, an old racket ball, but pretty much the same thing.

  • lol put a criket in ther or sumthing

  • I actually did that once. I watched it fry to death. It was still moving around for a long time, corona shooting out of its antennae. It was hilarious until it started burning, then it stunk.

  • i had a real thrill watching you shock yourself thanks lol

  • oh im sorry megasega i missread what you said..but no you dont need a 555 for this type of coil...just need a hv source,charge a high voltage capacitor with it and discharg it hrough a spark gap into a primary winding and that is about it...you have to have knowledge about it to get a good spark

  • hey mega sega..add my because i can help you with a few projects probably...i know a little about solid state tesla coils...but if you were asking if you could connect a 555 to the tesla coil then no...you need to connect it to a mos-fet..but if you know about high voltage i suggest a spark gap coil first

  • hi Im 11 years old

    hey do i really need a 555 timer or can i just tap the connection or i dont really need to control the pulse of it (i think i could use an alternating currnet but how it will produce the lighning at the other part of it)

    Hey how did youmade your toroid and also i have a tip for you TRY USING IGNITION COIL AND MAKE A 12v TESLA!! and it will also cheaper than a neon sign transformer

  • That's seriously AWESOME that you're getting started on this stuff at such a young age! You're most likely going to be an engineer or something. Anyways, I don't do too much solid state stuff, and there are no integrated circuits or anything in simple spark gap tesla coils. I really want to get my hands on a ignition coil, but I haven't been able to get one yet.

    You should get some videos of your electronics stuff! I'd love to see them!

  • Ah, i remember when i was at 11 years... I played around by a multivibrator driven ignition coil... I should now try to make a working flyback (and a little tesla coil with it - my secondary former will be a 15cm tall vitamine tube which is polypropylene or polyethylene)

  • Got plans?

  • Not really. I just kinda improvised as I went. I mean I used the typical tesla coil resonance formulas for tuning it, but besides that, I just kinda figured it out as I went.

  • ps3 rocks

  • OOOOkkayy?? O_o random

  • if you lick ur finger or wet it the skin affect happens easyer so you berly feel any thing i do this with a tc that makes 1/2 foot arcs

  • it is surely hot isn't it?

  • This is a really good coil.. i dont think u have the right resonant frequncy dont forget the tesla coil isnt just any old air core transformer its magic becuse it amplfies the enegery by a kind of pendulating effect in the secondary so if u got it to resonante equally u might get some small corna or maybe just larger streamers to a gorunding rod

  • A pendulating effect... a current is induces and pushes electrons into the toroid, I got that. And then another current is induced, how is that one more energetic than the last one?

  • As usual, I remembered after asking the question, that the secondary is ringing.

    I 'toopid.

  • the coils resonat at the same frequency a magnetic shock wave moves up and down the secondary nanoseconds after the primarys megnetic feild collapses. by the time the shock wave gets back to the bottom the primary coil explodes with a new megnetic feild and more engery which shoots this shock wave back up the coil when there in resonance...

  • so basicaly its like in the coil world its refered to a kid on a swing and every time they come back down you give them more energy in every push there is a lot more to a tesla coil that meets the eye

  • pretty cool!! -- dude!

  • on a tesla coil if it has a higher power it is generally more dangerous not because of the high power directly but because the higher the power while the voltage remains relatively constant meand higher current which could become dangerous because the tesla coils voltage definately overcomes your body resistance and if the current gets to a lethal level then it will kill you

  • Well, the output from the secondary is high frequency, the nervous system doesn't respond to high frequency so it wouldn't electrocute you. Of course, that's assuming that the coil is well tuned. If not, you could get low frequency mixed in with the output and that could be lethal. And you don't want to get directly by a discharge from the secondary, that can cause burns. Also, the primary circuit is extremely dangerous. It's high voltage AND high current, and is 60hz.

  • the nervous system does not respond to high frequency but it will still do damage and it will still flow down the low resistance nerves. don't quote the skin effect because at TC frequencies the skin depth of human flesh is still about 60 inches!!!

  • how do you make the foil ball at the top is it hollow or solid???

  • I took a racket ball and covered it with aluminum foil and some aluminum tape.

  • i still can't get over that "Ow, ow- it doesn't hurt because of the frequency"

    Surely you got some nasty RF burns on your fingers, man?

  • Yeah, I've gotten a few lol. You can't really see them but boy, you can feel 'em!

  • I got my hand too close to my Tesla Coil one time and got hit by a spark...it hurt like hell and I still have a small scar on my hand.

  • thats probably from the uber high temperature of the spark !!!

  • oh preach to the choir a bit why don't ya. Hehehe...

    Would you take RF burns over 60Hz shocks?

  • eh? I meant that for the pmdvy dude...since he was talking about how Tesla Coils can be lethal. The secondary is mostly harmless if the coil is tuned right, it's really the primary circuit that you have to watch out for.

  • Loool I laughed soo hard, Ow Ow ,, Ow !! Ow ... OW!! Ow.. xD That was funny rofl

  • cool capacitor ;)

  • my doctor said "if it hurts, don't do it"

  • Dude, don't draw sparks with your HAND! I left a comment about this, but don't ever draw sparks from the secondary with your bare hand. Yeah it hurts, and it will also burn your fingers. Hold a conductor in your hand, like a metal rod and draw sparks with that.  On a bigger coil, you would NOT want to get directly by a streamer. Very nice coil, but you're dumping a lot of power into it if the transformer is 12kv at 30ma, you should be getting a much bigger output.

  • Yep I accidentally let the arc strike my finger for too long and it left a black mark. And my transformer isn't 12 kv. I sadly discovered that the transformer only outputs 6kV at most. I didn't realize that when i bought it, the input was 277 volts. The most I can get from the variac is 140. But, I have ordered another one that really is 12kv and I should get it soon.

  • Well then, actually that's not too bad with only 6kv input. My coil uses a 6kv furnace transformer. I have a couple videos of it on my page. That's amazing that you're doing all this and you're only 15! Just be careful! I started experimenting with high voltage when I was about 19.

  • how many turns on primary and secondary do you have ?

  • DO UR WHOLE HAND

  • Are you running the NST off of mains? If so wouldn't the out put be more like 50/60 Hz not 2 Mhz? I supprised that a coil that small even worked on that voltage/amerage, i gussing 30 ma. But then again I never even thought of trying it. Other than that nice job, nice quiet gap too.. :)

  • Yes i am running off the mains. The frequency coming directly from the transformer IS 60 Hz.

    The resonant frequency of the primary LC circuit is 2mhz, not the mains. The NST outputs 12,000 volts at 30mA.

  • "Ow Ow Ow" lol

  • this is just basicly a really complicated van degraph generator

  • Sort of, but not really. Van de graff generators generate static electricity. Tesla coils step up alternating current into high voltage and high frequency. It would be more related to a really complex wall wart transformer :)

  • it wouldnt hurt if you have the electricity go into the middle of your hand if it has more base it wont hurt as bad because bigger area to travel threw i did this test with a ac/dc converter to create a shock machine

  • No, it's not even similar. I suggest you read up on Tesla coils and Van de Graff generators. Tesla coils are resonant AC devices, a Van de Graff generator is a triboelectric high DC voltage device.

  • try to fiddle a bit with top-load dimensions and primary windings. This coil could do much better. Keep up the good work.

  • i want to make a real tesla coil one day, but my one only makes 1/64 inch sparks that charr skin black and deep and causes everything else electric to 'fry', could you do a 'how to and what not to do' video?

  • cool thing^^ C&C style :D

  • damnnnn did u learn that in school? hahaha

  • Yes and no. Depending on how you ground the coil, the frequency of the primary circuit, and the power of the coil, sensitive equipment could be disrupted in different ways. With my small coil, I am able to use the house ground for the secondary without destroying anything. But everytime I run my coil, if my family is watching antenna tv, the picture goes all static-like. I think this is just because the frequency of the secondary is near the antenna tv broadcasting frequencies.

  • Some people who have made large tesla coils have fried modems, computers and other things by running the coil simply because the high voltage is not isolated enough from the house circuit. Another thing that would affect sensitive equipment is the high frequency kickback through the transformer and into the mains circuit. This is usually prevented by using some sort of filter in the tesla circuit somewhere near the outputs of the transformer.

  • This can be a safety gap, high frequency chokes(what I used), or ,the most effective, a "terry filter" which is basicly an assortment of metal oxide varistors, resistors and a spark gap.

    Generally, you probably don't have to worry about your first coil screwing anything up unless you build a perfectly tuned coil larger than 6" in diameter and power it with one of those pole distribution transformers (yes serious coilers actually use those beasts).

  • haha lol, good job volts dont kill you, amps do :P just make sure u wear rubber shoes haha and also use ur right arm idiot not ur left, then if the electric travels through ur body it wont pass ur heart.

  • No...Wattage is what kills you. A high voltage AND high current. I'll go grab jumper cables from a car right now, and it won't do anything to me...even though it's hundreds of amps. But it's only 12 volts. In order for an electric current to be dangerous, there has to be enough voltage to overcome the resistance of your body. Current = Voltage divided by resistance.

  • Actually, it is a current that kills. Not Wattage!

    Amper is deadly. Watt is ok. :)

  • No, it's both. High voltage AND high current. I can go grab jumper cables on a car right now and it won't do anything to me at all even though it's hundreds of amps, because it's only 12 volts. It takes a higher voltage to overcome the resistance of your body. Current = Voltage divided by resistance.

  • just don't touch with a pin!
