  • if the arch touches u is that dangerous?

    

  • @kennyman08

    Yes, it can be, in some circumstances. The output from a Tesla Coil is very high voltage at high frequency. Your nervous system doesn't respond to high frequency, so you won't feel a shock. But you don't want to get hit DIRECTLY by the arc because it can burn you. Also, if you don't have the coil tuned right, it might have low frequncy (60hz) in the output too, which would shock you. I've never had that problem, but it is possible to happen.

  • Wasn't the Tesla Coil at Wardenclyff designed to collect and then distribute free electricity absorbed from the surrounding charged air without an outside power source?

  • @Itsmeeman1

    No, the Wardenclyff Tower was meant to TRANSMIT electrical power, without wires. But it still required an external power source. Tesla never intended a device that would magically pull energy out of the air. That's not what he was working on. At one time, he suggested it might be possible to build a device that could generate power by absorbing cosmic radiation (similar to a photovoltaic cell today). But not something that magically created power from nothing.

  • ...you have to be very careful about what you read about Nikola Tesla. People try to make all kinds of bogus claims and conspiracy theories about him involving "free energy," UFO's and a lot of other nonsense. You should read a good biography about him. I'd recommend "Man Out Of Time" by Margaret Cheney.

  • @ct92404 Thank you for the reply.

    I've seen Tesla's designs on how to absorb charged particles from the air and gather them as a form of static electricity then use that power to produce work in devices. I was waiting for someone to mention photovoltaic cells. Tesla's were a more primitive precursor to them.

    Still, the electricity would be gained passively, stored then pulsed for use. A 'trickle' collection of 'free' or 'renewable' energy. Depending upon which term you prefer to use.

    Ciao

  • @ct92404 oh yes stop the real thinking and thought schill !!

  • I was killed when I tried this at home. Now I'm writing this from some parallel universe, hi there guys.

  • @demo1davis A death wish...

  • I have a question about the buildup. I'm having difficulties understanding the whole deal about Farad and capacitans. I'm starting to see that a low capacitans in a condensator will let it charge faster at a lower output amperage. But in a tesla coil would there be a relation between the condensator, transformer output and/or supposed frequence? Is higher or lower Farad best for TC's?

  • You have done a very thorough & explanatory video on this - Nikola would be proud of your work! Thanks for sharing.

  • i have 230v what should i do?

  • Dear Mr. Tesla, we are sorry for what this world did to you. We will bring your dreams to reality. We begin here: divinerighttechnologies.webs.c­om

  • Couple of questions, the mains voltage over here is 240, and the "hot" is called "live". Out of curiosity I've tested the voltages between neutral and ground, and I've found that there's about 120 volts between them, there is also about 120 volts between the live/hot and ground, so would I have to connect it up differently?

  • Made by Serbian , Nikola Tesla :)

  • a ver si saben que quiere decir esto, °eat kk° juas juas juas...

  • Hello,

    could anyone who reads this please answer these questions:

    - What happens if you hook it up to a german 220 line? instead of 120

    - Does an increased ma mean you can transmit further distances?

    - Is this safe to use inside? Lets say we have an office with a room like 8 by 8 meters, and next to that a room attached of 2 by 2 meters, would a good tesla coil power all the lights in the 8 by 8 room? (i think yes)

    please answer :)

  • how much did the whole project cost you?

  • @bossdzony "Secret Journey" by the Police

  • what would happen if you hook it up to 220V in place of 120V? here in belgium its 220

  • @patton446 I'm curious about that too! Plz answer cause this is gonna be my new science project.

  • @JUKONGTH it is a possibility that you would burn up the transo whit the amps, and you would need the sparkgaps to be bigger.

  • Is it at all illegal to generate your house with a tesla coil?

  • @DarkShadowMegadeth

    No, Tesla Coils are not illegal. In fact, a lot of colleges have them in their science or engineering departments. They're perfectly legal. But a Tesla Coil does not generate power. It only converts power to high voltage and high frequency. It does NOT generate electricity on its own. You need to power it with an external power source. 

  • @ct92404 I don't under stand, whats the point if it as to be powered by an external source, didn't he create free energy or is that a different topic or invention

  • @junkie654

    Nikola Tesla was working on a way of TRANSMITTING energy without wires. The point was that he wanted to build a system for transmitting electrical power without using power lines. The power plant would have an antenna, kind of like a radio station, and to receive the power all you needed was an antenna and a circuit tuned to the same resonant frequency. Just like how we pick up radio signals today.

  • @ct92404 JP Morgan ensured that Tesla tech would never be released to the public. He practically ruined Tesla because his ideas would have cost Morgan alot of money.

  • ...Have you seen that movie "The Prestige"? That scene where they are outside and Nikola Tesla's assistant shows the field of light bulbs being lit up by a power station several miles away (with no wires) is actually based on a TRUE story. Tesla really did an experiment like that in Colorado Springs. That was one of the most awesome scenes I had ever watched in a movie, because I knew it really DID happen. You should read the book about Tesla, called "Man Out of Time" by Margaret Cheney.

  • @ct92404 will it hurt you if you touched it? or does it just raise the voltage and lower the current?

  • your video is down

  • Great job on the Tesla Coil videos. Your coverage of safety, history and formulas was excellent. Thanks for your contribution.

  • @cliffhanger625

    Thank you! I'm glad the video was helpful.

  • it's the nice video, have you make the project paper ? If yes, please email me/ inbox me.. I want to build one...Here in my country it's pretty difficult to find out neon transformer, any better idea?

  • ok Where can u get a transformer thingy?...Actually im in the 7th grade and i just wanna do this for a science fair :D Umm Where could i get a transformer thingy? first question and could someone possibly guide me throughout the whole time i'm making it i would be extremely greatfull!

  • @DeathStrike132

    I'll send you a message.

  • @ct92404

    Im pretty much in the same position as Deathstrike. Could you let me know where i can find a preferably cheap transformer?

  • @DeathStrike132

    Transformers?...you can get a Home Depot. Its for Floresent Lighting. All the info can be found on the web. Do it...you will blow people away!

  • Extremely well presented! You are an excellent speaker, and the content is very well organized. Your diagrams were equally beneficial. I found this video series to be informative, clear, and more helpful than any other I've encountered.

  • The same thing you do at 4:43 on your video, capacitive reactance may be added. This is how they exactly do in microwave oven. Capacitance close to 1 uF give exactly good protection for this type of the transformer.

    Formula for capacitive reactance is very similar to hat one of inductance:

    XC=1/(2*Pi*f*C) where XC is reactance of the capacitor in Ohms, 2*Pi is omega function, f is frequency, and C is capacitance.

    So, 1 uF will give 2,652 Ohms, at 2000V it is 0.748 A, and P is about 1500W.

  • Starting from the time 4:08 on your video, there are multiple choice. You are right about being impractical using light bulb as current limiter. Series inductance is impractical too (difficult to find proper coils/transformers). But, one thing keep in mind: while series inductance gives you inductive reactance (in Ohms) with formula XL=2*Pi*f*L, where XL is reactance of the inductor (in Ohms), 2*Pi is omega funkction, f is frequency (60 Hz in USA, 50 in Europe), and L is inductance.

  • Comment removed

  • What exactly would a tesla coil do if I say, turned it on in the middle of my room?

  • @NaRcOlePtIcLeMur

    It would cause a lot of radio interference. If you have a stereo in your room, it would pick up a loud hiss and hum, etc. Otherwise, it wouldn't really cause that many problems except that it would be really loud. Also, you probably don't want to have it plugged into the same outlet where you have a computer plugged in.

  • @ct92404

    Thanks, I was hoping to buy/make a tesla coil and figure out how to link it to my keyboard. I'd love being able to say "Oh yeah, I play electricity."

  • @ct92404 but does it have a use?

  • @ct92404 Where can i get that furnace transformer thingy? if u could guide me step by step through the whole thing that'll be great... I'll start piecing it together and probably make a vid out of it.

  • ok, kind a new to electricity...So Coil is a delivery system?

  • @nmssis

    Well, if you're new to electricity then I'm not sure exactly how to explain it best. But a Tesla Coil is a type of transformer that changes electric current to very high voltage and generates radio waves. I suppose in a way you could call it a "delivery system" since it could be used to transmit power. But it does NOT generate power by itself.

  • @ct92404 so it's like an electric 'pump'... from one circuit (with certain load capacity) to another circuit (with another level of load capacity)?

  • @ct92404 its a long thingy that sends off pretty lightning :3

  • Thank you.

  • can i use 10 600 volt lamp ballasts in series for my voltage transformer?

  • @geekydude21

    Theoretically, I suppose you could. But something tells me that wouldn't really work right. For one thing, would that supply enough current? You really need at least 20ma. The other issue is whether the ballasts are AC or solid state. I guess the only way to find out is to experiment and try to connect them in series and see if you can make a high voltage supply with them first. If that works, then maybe you can try it to power a Tesla Coil.

  • How would i modulate Hertz of arks to produce sound

  • I ASKED IF SOMEONE CAN SHOW US TO CREATE THE ANTENA, WHICH GENERATES ELECTRICITY, WITHOUT THE POWER COMPANY OR GENERATOR? BECAUSE HARNESSING ELECTRICITY IS THE FIRST STEP? ANYONE?

  • @xavierz71

    a Tesla Coil does not generate electricity on its own. It only converts it to high voltage and high frequency. You still need an external power supply. It is possible to use Tesla Coils to transmit and receive power without wires, like a radio signal. In fact, that's what Nikola Tesla was working on. But you would still need an energy source.

  • @xavierz71 big wireinto the sky, and a 3ft copper pipe in the ground, and water it. the frequencies can be picked up and made to trickle charge batteries or more, depending on size and number of rods in the ground.

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

  • I've never seen a tesla coil run from a car ignitioncoil even though these output some serious voltage from only batterypower and are fairly cheap and available. Is this because the inputvoltage to the tcoil would mess up the sparkgap or is it simply not doable running a tcoil on 12V DC power? I'ld like to build one but these questions keep popping up...

  • thanks for posting this. good vid.

  • Very nice video

  • helpfull to me mate. thanks

  • I always wanted to build a tesla coil, but I am too afraid of making a small, but deadly mistake. Tesla did a show at the worlds fair using his coils. it would be neat to see a vid of the things he did.

  • Capicitors are used for make voltage more stable right ?

  • @007foppe Capacitors are a means of storing energy. I do not know what you mean by "stability". Do you mean that they keep the current constant? If that is what you mean, a constant current is dependent upon whatever the power supply is. By constant current, I mean that there is a current running through the object in question until the thing supplying the current is disconnected/turned off.

  • My main problem with building this stuff is: Where do you even GET the things needed to build it?

  • @wiseidiot5763 You can find many of these things inside household electronics, but it's not usually worth taking these items apart considering the prices of the electronics you would have to buy versus the prices of the individual parts as long as you know exactly how to make all the things necessary for this from scrap. Otherwise, you'd be better off taking things apart and using that stuff rather than trying to make everything yourself.

  • @wiseidiot5763 However, you should have a VERY good understanding of how circuits work and knowledge of magnetism, electricity (electric fields, flux, etc.), and how to construct circuits and these kinds of devices safely and correctly. This video does not teach that knowledge. It only tells you the general premise of what you need to construct a Tesla coil.

  • ... how about you make it for me? XD seriously though, these are awesome.

  • what would running a coil with...say a computer within the vicinity do to it? or a tv?

  • Hi, I have watched all three of the videos in this series and I have found them to be very informative and well laid out. You have done an excellent job in explaining the principles of a Tesla Coil and you have also excited my interest.

    I have a few questions however. Knowing that the coil will have to be tuned anyhow, will a capacitance value of .01 mfd be acceptable? Also, Will this particular coil design cause harm to nearby electronic devices (Ham Radio sets, PCs, etc.)? Thanks a lot!

  • Hi. Just wondering if you knew where I could find a cheap Neon Sign Transformer as I am doing this for a school project, so do not have a huge budget. Also, how large would the streamers on this be?

    Thanks

  • the tesla coil was designed in 1800s

  • Can you use an FBT?

  • Thanks for making this video. My uncle and I are attempting to build a Co2 laser. Any tips? Also this video was extremely well done as far as information. I might attempt to build the Tesla coil.

  • HeHe

  • Hello all. Listen, I'm fairly new to the electronics world, but someday soon I hope to build one of these mothers. Can somebody point me towards a VERY detailed schematic for a Tesla Coil?

  • is it better to use a static spark gap?or can i get the same results with a normal spark gap?

  • Really cool video. you have inspired me

  • tesla coils are awesome in every way...but they're so fuck*n' creepy

  • @Harisdoubled

    LOL...yeah, they are a little scary. Even I sometimes jump a little when I first turn on my Tesla Coil, and I BUILT the thing!

  • @ct92404 when i hook it up to the 120v outlet is it safe to strip a plug from a extention cord and hook up the wires to that? im asking cuz there could be a drawback from it that i dont know about.

    also, how big should i make a safty gap with a 6k transformer i dont wana make it to big and it becomes useless

    and 1 more thing. its rly noobish. but by grounded you just mean attach the ground line to a pice of metal for safety? i'm sorry i needed to ask that but i never got when it said to ground

  • your wiring diagram is wrong. you need energy to bounce between the tank capacitor and the primary several times for each spark gap firing. your setup will work, but wont be optimum. the only spark gap should be where your safety one is in the circuit. its the repeated vibrating between the tank cap and primary that creates the very high voltages. it goes HV supply hot to tank cap to primary to hv supply neutral. the SG goes between the hv supply hot and neutral before the tank cap and primary.

  • @TestTubeTony

    I have built several Tesla Coils (I've been experimenting with high voltage for over 10 years) and I've seen designs for both ways...where the spark gap is connected in series or connected in parallel. Also, I've shown my Tesla Coil to a technician who builds HUGE coils (powered by 15kva pole transformers) and he said the way it was connected was fine.

  • @ct92404

    i want to build one with the capacity to put about a 20 sq. yd. together with fluorescent bulbs stacked on its perimeter. do you have any idea's

    AMA

  • @ct92404 Right On!

  • @ct92404 so do you have a website with a complete design which will work? I want to make one home-made and as cheap as possible. My first one..

  • @TestTubeTony Just made a tiny Tesla coil using this diagram but without the safety spark gap and it works. Then I exchanged the position of the capacitors with the spark gap switch in this diagram and it works too. So it seems to work either way. I used the transformer from a discarded bug zapper..

  • @TestTubeTony, Can you or someone make a video. Where it is shown how to do this without no electricity, I mean from the power company. There was no power company when Tesla was doing this. First show me how to build the antenna which charges the coil.

  • @xavierz71 Alright you take a generator; hook that generator up to the tesla coil; turn the generator. Voila

  • we can use this technology to create a conduit to allow the ambient energy caused buy the friction of the planet against the ionosphere to flow into a static mill made out of permanent and electromagnet. Like a wind or water mill all you guys trying to find 0point energy .make one of these then run it in reverse and hook it to your device and that is where "the power " will come from

  • why don't we use this tech? I be aliens use it ಠ_ಠ

  • wouldnt you have more voltage if you hooked the microwave oven transformers in parallel with each other? because that way you would see the full voltage? great vid though.

  • @Crashromeo100

    If you connect the transformers in parallel, that would increase the current capacity, not the voltage. In order to increase, or double, the voltage you have connect the transformer secondary windings in series.

  • I can't find the other videos in the series, Could you please put a link in the video to link each of the videos together?

  • This is probably the best vid I've found on the topic. :-)

  • Awesome video and sound quality! Great work.

  • at least somone who know what is talking about

    good video

  • so wait hold up im electric illiterate, this tesla coil thing uses electricity then multiplies it by substantial rates??? is that what it was saying about the "hot 120v" turning into 15,000v?

  • Hello there, even I won't be making a Tesla Coil, if the NST has 2 HV outputs, could you connect all the neutral side of the parts to the other output of the NST?

  • can you use a microwave oven capisiter for the high voltage capastier for this project?

  • You should switch the place of the main spark gap and the tank cap to cut down on the resonant rise which can damage the transformer

  • i have a question. how does the secondary connect to the rest of the circuit? it looks so very detached in your diagram. does it connect? thanks in advence :)

  • @flargrbargr

    The bottom end of the secondary winding is connected to ground (or you can also use the AC neutral line). The other end is connected to the output terminal.

  • @ct92404 the ground as in the ground of the capacitors?

    is that the same as the AC neutral line?

  • so i just bought a 15kv nst what should be the specs for a tesla coil built with it? also would beer bottle caps work for this?

  • Tesla made earthquakes in 1899. That riddle of Tesla killed the Illuminati Freemason with a simple truth that prevails.

  • so, the primary winding and the secondary winding are sperate?

  • What r your thoughts on Flyback Transformers? Havent been able to get too much information about them. Would a Flyback from an old CRT monitor Supply the right Voltage/Amperage with a 120VAC Input?

  • Could I use a transformer with 9000v at 30mA?

  • yeah, that should work fine. 9kv should be perfect actually. It's not too high or too low, so the spark gap would be easier to adjust.

  • yes. he says from 6000 TO 15000 so anything between will also work. ;]

  • im testing my first tesla coil tomorrow, it has a 10 kv nst rated at 25 mA. i hope this isn't my last post on youtube! :-O

  • You can also use an ignition coil as transformer. Input Voltage is 12V DC and Output VOltage is 10kV DC. If you use 2 of them you have 20kV DC. You can do something with that :D

  • All kidding aside. 14Ga wire is the bare minimum for residential wiring. I don't care if a source you can't quote told you 3a. You have to consider the wire heats and it's resistance changes. Besides the electrical code says so. Find and old lamp with at least 16Ga, and use that. Is it worth having the guys at the fire dept laugh at you (behind your back)

  • would you plz plz!!  make a tutorial video.....

    step by step please!!!!! cuz a don`t understand how to do it !!! :O

  • if you dont understand how to do it you probably shouldnt mess with a tesla coil...

  • i agree with marco.. if you dont understand how it works you probably shouldnt be messing with it. thats a lot of voltage. and if you hook up the transformer backwords. thats a lot of current and you could die. maybe understand it first aye?

  • @giggity428

    yes thank you!! : ) the thing is that im not from usa and my native lenguage is spanish and i dont understand cuz im not an english master and! there are no tutorials in espanish : )

  • so if the transformer is a 9k at 30 ma can i use 18 awg wire? i have no other wire and cannot get any other wire.

  • Yeah, 18 AWG should be ok for the AC input wires to the transformer. But I have a question for you...if you can't get any other kind of wire, then how the heck are you planning to build a Tesla Coil? Where are you going to get the magnet wire for the secondary winding? What are you going to use to build the spark gap and safety gap? Surely there is a hardware store somewhere where you live, right??

    My point is if you can't even get 14 AWG wire, then you're going to have bigger problems.

  • I am really comfused... how did u guys learn all this stuff? other then playing around with the outlet.. xD did u have a book or something?

  • Well, I've been experimenting with high voltage for over 10 years. I've always been interested in science, ever since I was a kid. But I became more interested in electriicity after I started reading. It's kind of a long story actually. I got interested in Nikola Tesla and I decided to build a Tesla Coil.

    I started reading more and doing more research online. This was back in the late 90's (around 1998 or so)...way before YouTube and every kid was building a Tesla Coil in his garage!

  • Wow... too bad now everyone is on facebook and stuff (not me) and i have no other friends that know the subject. But, i did learn what a transformer is, i think its supose to decreas or increas voltage without effecting the Ampage. Its primaraly used in electrical lines to keep the power flow.... i think >_>

  • That's pretty much correct. A transformer can be used to increase or decrease the voltage. The amperage is also changed, but the overall amount of POWER remains the same. Power is Volts X Amps = Watts. So, for example, 6 volts at 2 amps is the exact same thing as 12 volts at 1 amp. They would both equal 12 Watts.

    It's the same as how 1 dollar is equal to 4 quarters. If you change a dollar bill to coins, the amount of currency is the same, you're just changing the form of it.

  • thnx :)

  • can you use 18 awg wire to connect everything together?

  • I normally use 14 guage wire. 18 AWG would be okay just for a temporary connection, but I probably wouldn't recommend it for a permanent hook up.  Esepcially not for the 120v input lines that go to your transformers, since depending on how big the transformer is, it might draw a lot of current.

    It really depends on how big your Tesla Coil is, but I think you're better off with 14 AWG.

  • @ct92404 i will be using a 9000v 30 mA transformer and all i have is 18 gauge wire and im not able to get 14 gauge wire. i read somwhere that 18 gauge wire can handle 3 amps

  • HAARP its like a big TESLA??

  • This music reminds me of Portal

  • thanx heaps...i learnt something new today :)

  • Where do I get a transformer?

  • Ebay. SignTimeLLC is the person I got it from.

  • find an neon sign shop

  • um, ok i am building a tesla coil, this may sound stupid but i'm scared to run i read alot of saftey threads and im worred something bad will happen, how dangerous is this really, i have a mid point grounded transformer, (only 2 input prongs) so its not grounded, do i have nothing to be afraid of, or am i a big scaredie cat?

  • put it in a glass box.

  • I personally used an old industrial microwave transformer. Because of this the most expensive thing in my project ended up being the base which is lined up with neon bulbs for external resistance.

    I've been working on a miniature teleforce. It's hard as fuck though working with a restricted current level because of space, safety, and money.

  • Can I use a 27kv dc transformer with 15625 Hz

  • is the power consumption very huge?

  • It depends on how big you want to build it...but generally, no, Tesla Coils do not need that much power. For example, the small coil I show in my videos can generate over 100,000 volts but it uses only 120 watts of power. A computer uses more power than that.

  • wow, a good cost-benefit. i can't imagine why the hell we still haven't wireless electric power transmission...

  • Because people conduct electricity, resulting in fatalities. Also shooting electricity through air over long distances is very difficult. You would need repeater stations every couple dozen feet. Air just doesn't conduct electricity that well. Copper does.

  • Few things conduct, but everything has flow. The earth is a giant magnet, with frequencies that are higher than ac. The potential difference between a cloudless sky and ground is 100 kv roughly. NICE!

  • thanx for the info. i was checking out this video for info on power consumption.

  • Where can you buy a transformer and for how much?

  • Look in electrical surplus shops and neon sign shops. Back when I first started experimenting with high voltage, I just found a neon sign shop and asked them if they had any old or used transformers I could buy. The guy I talked to said they had an old 15kv transformer and he let me have it for free! If you're lucky, sometimes they will sell you an old transformer for cheap or maybe even give it to you for free. Also, look on eBay.

  • Ok. Thanks.

  • Hey ct92404, it's me again. I've got one more question. I found a pulse capacitor, well four, on eBay for about $90. They're rated for 35kV, far more than I need, but the peak current is a few thousand amps. Should I use this capacitor? To get the same result from $3 capacitors, I'd need around $100 of them. I just want to know which I should use.

  • To me, that sounds like a good idea, but it depends on the capacitance value. The current will be limited by the transformer, anyway (you are using a current limited transformer, or some kind of an external ballast, right?). Your main concern for the capacitors is the voltage rating and the capacitance value. Do you know what the capacitance on those capacitors is?

  • Yes, I am using a current limited NST. It goes to 30mA. The capacitance on those pulse capacitors is .03uF each. Is that good enough?

  • Sorry it took me a while to reply. The capacitance value might be a little bit too high...but that's really no big deal since you can just connect two capacitors in series to divide the capacitance.

  • Ok. So, if I hook them up in series, it'll add the voltages and divide the capacitance?

  • how could I make a true free energy tesla coil?

  • @JohnnyCashFan01 you cant. Because you have to use AC current from, say, the house. Now, if you had an extremely powerful dynamo powered generator, somehow perhaps you could come up with 120 V to power the NST and the tesla coil, but good luck with that.

  • quick question...does it need an electrical sorce to start....like an in home electrical sorce or is it a type of free energy?

    Also if it is a type of free energy how could i power my home with it?

  • A Tesla Coil is not a "free energy" device. It doesn't generate power. You connect it to a power source, usually 120 volts AC from an outlet. It converts the power to very high voltage at high frequency. Tesla Coils only transformer the power, it doesn't generate power.

  • making one for science class. thanks for the help.

  • cool..now i know how to stop the cats crapping in my yard......

  • hehe i want to make a tesla cannon from fallout 3 lol well actually that might be possible hhhhm any suggestions?

  • @bobmarleyt3 same dude should be able to with the right equipment.

  • first i need a tesla coil that is the first challenge

    this is gonna need some planning

  • SRBIN!!!!!!

  • these coils are not tesla coils. simply its a Rhmkorff coil. the other name is the ignetion coil. or the induction coil. by the way there is one in every car next to the battery. it takes the 12v ov the battery and gives 10,000v to the candels.
