A few decades ago (like in the early 70's) in high school, a buddy of mine made a Tesla Coil for a science project. He was a nerdy genius. He waited until the night before the Science Project was due to build it. This thing was 3-1/2 foot, maybe 4 foot tall. He brings it to school and you can still smell the varnish paint on it. The varnish was also used to hold the fine copper wire together and make it look professional. He had a copper toilet-tank float on top too. This thing actually worked, plugged straight into the wall! With the classroom lights off, the fluorescent light in the ceiling above the Tesla coil was glowing a bit. A big purple looking bolt of plasma zapped out and caught the varnish on fire. The whole science project was flaming on the desk. It burnt and charred the ceiling. It was a mess.
F
In fact, he was a genius ..... :D
sometimes we must sacrifice fire safety for science
Heyy! Is he alive ? Can I talk to him please ? It's urgent .
@@yeahright3804 - Unfortunately not. He died a few years ago.
First, let me say this is an inexpensive build which is wonderful new to tesla coiling, So Kudos to You and your engineering. However, here is some truly Respectful and polite Constructive Criticism. I love the sky blue tub you chose to use as a coil form. Make it a little longer, your coil winding was gorgeous, the tape ruined the Aesthetics of the build, a nice couple coats of Krylon clear coat would've set that off. Make a nice base or buy a small tub, like a can of DAP drywall repair kit, it is small, cut and drill a wooden dowel to fit the inside diameter of the tube, drill a hole through the top drill some holes to secure via a nylon nut & Bolt., You could self contain the electrical components. Drill holes for small wire terminals. Just a thought, the Corona discharge for it's size made this a very cute and fun coil. Please be proud of your ingenuity, these were just some thoughts, I threw out there to chew on, happy coiling!
Bro I have a question
Will this surely work.
@@t.nitheesh5898that’s a statement, not a question.
After looking at different solutions for a DIY tesla coil I decided to try this one. The difference between the original and my build is that I used 0.2 mm wire for the secondary coil and 1.5 mm for the primary. The secondary is made on 50 mm diameter tube with 1000 turns (21 cm long), the secondary with 5 turns. The transistor is the D718 and everything is connected according to the video. And to my great disappointment it did not work. A few videos explain that you should try to switch the connections to the primary coil, but this did not make the project work. Then I made a new primary coil with the same orientation as the secondary coil: "clockwise turns going downwards" and not as seen on the primary coil in this video which looks like it goes the opposite way round. And what a relief to see the whole thing work! Sorry, my English is "Danish" :-)
This absolutely works. There are many variables to consider whenever making one, so if it does not work for you right away that doesn't mean American tech is lying. Consider adjusting the resistance, voltage, turns of primary coil (outer coil is the primary coil,and I recommend 4 turns), and consider there are many variations of transistors with differing input points.
Sir, if I would wanted Tesla coil up to 100kv and to be able to take a 20khz square signal, what would be specifications of that coil... Wire, turns etc...
AT is a genius
So i agree he works just about any thing he's very smart
Brush clear cloat on your coils instead of taping the whole thing.
Trust me. The clearcoat holds better, looks better, and provides extra insulation- you need as much insulation as you can get so your magnet wire doesnt start to arc to itself. This is crucial if you want some big sparks.
Because then you can pump more energy into your coil without it destroying itself.
why would you use any extra insulation when you are already using magnet wire which has a coating already, even the big tesla coils dont use extra insulation
my Siamese cat jumps up and down whenever it hears that music!!
lol
In my day, we made our Tesla coils at least 6 feet high. Another good thing about the 1960's...
Hey I just made one today and it really does work! I am using a different transistor but it still works the same. It puts out a lighter and smells funny.
The untold wireless energy of nikola tesla
🌚
Yes the wireless energy that would confuse every computer on this plant into being an active high state on every signal simultaneously. Making any computer unusable.
Nah, its random bursts of microwaves x-rays and radio waves
@@Luke-sj7duyou can just power it wirelessly by charging the computer battery wirelessly independently and then going from there. There's devices that already do this btw
@GV5 A computer needs an active low and an active high to operate. Think about the operation of a single mosfet. Data can only be transferred as a high maybe 5v or a low GND(ground 0v). Without this fundamental trait the computer wouldn't work. You would cause failure by interference.
Made one in jr high school with a model T spark coil and a foil/ glass plate cap. My classmates were shocked.
Nice one
Nice pun
What materials did you use?
@@nyaramanneh2584 As above with hand wound coils.
Amazing...even with all those cold solder joints. Cool.
This guy doesn't know what flux is for !!! 🤯🤯🤯
What was your input power?
I have a few small transformers from small guitar amps I've been wanting to use for a project..
Ok, it is a kind of "slayer exiter". Thx.
Bro...
Did u use battery eliminator as power source??
Tamilanda naanum tamilanda...
I like your vids, maybe I'm idiot, but I'm sure, you'll get way more views and likes if you explain a little bit more what materials and procedures you use. Especially for non-tech viewers.
use voice not whistling music
yes at least a schematic will help newbies...
1)bottom end of the thick and thin wires go to the first pin " base"of transistor...the thick wire has a 10,000ohm resistor in between the connection to the transistor
2)upper end of thick wire goes to the second " collector" pin of the transistor
3)third " emitter" pin of the transistor goes to the negative of the power supply
4)positive of the power supply goes to the thick wire bottom end where it meets the transistor mentioned in 1)....
@fidel catsro No. Thick wire (Primary) and thin wire (Secondary) coils wound same direction. Resistor and bottom of thick wire to positive. Thick wire top to transistor collector. Resistor and bottom of thin wire to transistor base. Negative to transistor emitter. Simple.
proven, peer reviewed science; gotta love it.
I think the thickness of the secondary doesn't need to be that big since it's in series with a low power resistance
Excelente buen trabajo Felicitaciones
Nice. bt supply connection (i.e black wire) in winding is not clear. Bt over all it works. Excellent
I have clip open LED - Your video great!
Electroboom will save us by rectifying this video!
He already made a video about Tesla coils tho
Ya
The circuit is real
@@TechHowden then how come my curcuit here dosent work while his mumbo jumbo works like magnificent
I’ve seen it work
Your first video? You "generously" hide from us where you connect the black wire (negative from DC supply)! Without that, only those folks who understand the self oscillating circuit you intended will know where to connect...
To the transistors third leg?
Yes me too
which 3rd wire are you guys talking about? the first or the "third" i am getting confused...the left side from the base or the right side?
If you watching the metal (cooling)the first wire, if the plastic (where the writing is)the third
(Sorry for the bad english)
@@Gergix kķ
Thank you !! This was my very first Tesla coil that worked !!
could the starting of the secondary coil be connected to the top load?
Don't make too many turns off the primary coil (2mm) wire
making the primary is kinda tricky, isn't it? You need enough turns to make it strong but too much and the ratio is low
Does the primary have to be made out of coated or isolated wires? I've seen a couple of these but each one looks a bit different. One had the primary made from copper wire with a white coating or something like that.
@@fnollo7870 if it's not coated then it can make a short and it won't work
@@hubb8049 Thanks! I'm planning on making this as a science project so I'm trying to gain as much indo about it befote I start haha.
@@hubb8049 I have like 219 turns on the secondary and how much turn should I do on the primary?
If we add another small wire next to the one at 9:11 (like solder it on at the end), will the spark come on that as well? Like will that change the intensity of the spark? Also, how far will the spark go (like it stretched for the screw driver), what distance would this much voltage provide? Thank you :)
911 lmao
@@zblersqler7405 this guy gets it
I have a doubt.. should the LC resonant frequency of primary side and secondery side be matched?
This does not have a primary LC, and it is self resonant because the secondary provides the feedback to the BJT base. This is a Slayer Exciter, not a true Tesla Coil. A true TC uses a primary and secondary LC that has to be tuned by selecting primary L and C values to be close to the secondary LC, and tapping the primary L in the right spot to find the right res freq match. This is an inefficient circuit operating in class A and wasting a lot of power as heat, though it does find the right resonant frequency due to the secondary driving the BJT base.
You Don't Know the Power of the Dark Side
Emiter of the transistor
where do you connect negative terminal to ?
The emitter of the transistor.
Connect the right transistor pin to ground/negative, this guy forgot to put it in the video. Hope that helps
excellent .. well done
Nice work

God has said in the Quran:
{ O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
[He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )
Quran
The ratio will be less and so will be the voltage
That glue job absolutely killed my OCD, lol. It doesn’t show it anywhere that I saw, but power supply ground must go to the emitter.
american tech what tape and glue do you use to make the pieces of your projects (the blue ones)?
Don't use tape on the secondary coil, use epoxy resin. It protects superbly and looks so much better.
Power supply kaha se di......
Hey man what's the length and breadth of the coil??
Bahut acchi video hai😮😮😮
It's good idea
We only need to stick heat sin cut is that work ?
I think uou have to take a good soldering iron
Hi. Would a LM317T transistor work? I have some of these already.
Luar biasa kawan,, tfimaksi infonya😍😍😍
I have one question what is the purpose of this transistor if there is no switching because it is connected in saturation mode in this case, it means giving continues base voltage no switching how voltage at the collector will be boosted?
The base current is switched by the secondary, when the base activates the collector, current can flow over primary coil and create a magnetic field, when this happens the secondary coil creates a positive potential at the top and a negative one at the bottom, that stops the current to the base and the transistor turns off, and then the process starts again and again, its a self oscilating circuit called Slayer Exciter
Does the primary winding need to be copper can it be aluminum
Looks good.
ive been wrapping this pipe for 400 years
It certainly feels that way. Ya wind and wind, and the first time ya try to scratch the tip of your nose you lose your grip on the wire and the last ten minutes or so of windings come loose and have to be rewound and you just want to scream! Imagine winding a 4 inch diameter by 1200 turn coil for a vacuum tube TC with 26 AWG by hand. It's always a good idea when winding coils to keep a strip of tape on the coil as you go, wind ten or so turns, reposition the tape, ten more, reposition, etc as you go. That way if you need a break, or lose your grip on the wire, it won't unravel on ya. Also use a tape with a good stickiness too, like black vinyl electrical tape. Then once you're done winding the coil coat it with epoxy and it'll be solid and protected from insulation varnish damage from scrapes or hot corona discharges, or breakage and unwinding. Use a wide paint brush, and epoxy with a one hour work time instead of quick set so your brush doesn't harden on you before you get half way into it. Use a brush cleaner with xylene to clean the brush after.
Use drill to winding, good and fast :)
and in the end its wont work with you :D
@@wael_reg no work very well :) 4-5 cm sparks
Use a smaller pipe bro in that way you can wind it easily..
Wonderful 😁
Good2,,👍
Muy bueno y bien esplicado
the way it works is equal to ignition coil of spark plug in car or motorcycle
no!
not even close
It's only look's like Tesla coil, work's with "Hertzian wawes", original Tesla coil work's with "Non Hertzian waves"..anyway interesting construction, even working princip is apsolutelly different :))
Sir the D1555 can be use too?
!!!QUESTION: Can i use this coil with 12v 1A? would it harm the coil? What can i do to make the arc bigger?
12 v 1 A is nothing for a tesla coil....this video is hiding many components that he added to get high voltage arcs....tesla coil with input voltage 12 v gets converted into 2 K V AND may reach to 10000 to 15000 volt.......1 A will help you to see a little bit sparks.....5 A is good....this video doesnot contains the full circuit.....he is hiding.....get the proper knowledge of tesla coil' s component from PLASMA CHANNEL....
Amazing will be making one
Thanks for the information. Is there any limitation to designing the secondary to vibrate in the gigahertz range?
The coil would have so few turns that the voltage would be quite low
Im first viwer end liker or Commenter also
Where is the black wire from the power supply connected?
How to save time .... a cork and a power drill for the secondary windings .... thx for content
Why have so thick wire for the primary if your supply leads are so thin? Also, 13V at 300mA = aprox 4W isn't very powerful. Also, set your iron to a higher temperature, it barely solders. Also, why not use a top load?
The plasma is more beauriful but yeah
What is the equivalent of this transistor please ? Thx
Negative wire hooks to the emitter. NPN transistor.
What type of current should be used (AC/DC)??
Magician can do it with help of Tesla coil and luminate floleresent tube light and CFL bulbs any way super
Would there be any problem if 0.1 mm copper pitches come one on the top of the other?
Hello, I hope you get notified of this comment. May I ask why you added a transistor and what it functions as in this prototype? This looks really interesting but I am quite curious
bro got that 2 component flyback driver 💀
the circuit works but it has very low effciency due to the voltage drop of the transistor make it heat up quickly
so you need the mosfet which has very low voltage drop and the RF amplifier you can build with some C1815 transistor, inductor and some resistor to drive the mosfet
I hope he got an A+.
I know this circuit. But I do not know why it works.Where is the source of the oscillator circuit?
Please, please let me know.
And it is a nice video.
The oscillator circuit? This is a Slayer Exciter, a self resonant circuit operating in a very inefficient, wasting power as heat, class A operation. It works because the base of the BJT is taken high by the resistor to positive V, causing the transistor to conduct current into the primary. Negative feedback to the BJT base, from the bottom of the secondary, turns the BJT off causing the magnetic flux of the primary to collapse. The base is taken high again by the resistor and the cycle repeats. It self resonates because of the secondary feedback to the BJT base. A true Tesla Coil has a primary and secondary LC tank circuit that have to be tuned to the secondary LC's res frequency. This can be done by chosing a pri tank C and L that are in the ballpark of the sec res freq. Tapping the pri L at the right spot fine tunes the pri tank to oscillate at the sec's res freq.
What kind of material for wire you used
Very good
What is the frequency of the high voltage generated in the larger coil?
24MHz

How much current should u give 240 volt
@@rohitkarmakar1466 Do not ever give this tesla coil 240 volts. I would estimate the absolute maxiumum you can give it is 42 volts DC
If there's are space gaps among the secondary coil will it still work?
No,because the arcs will have the ability to jump to the other wire.
Can i use 24v dc
How much current did u supply it with?
Can it work with a K2749 transistor?
Soy el genio más grande del mundo 😎😎
Que transistor usaste?
Will 2sD718 transistor also work?
Where do you connect positive and negative wire of power supply??
Very good question.
In what part does the source of power weld? In the video shows only one pole at one end of the primary coil and the other? You have the circuit map I would like to try to replicate it. Thank you very much and I love your videos.
Cesar
See my other comment before you build.
Thank you very much, so protect yourself the circuit. But I still have a doubt about where the source is connecting? To the primary coil? To the base of the transistor? To the secondary coil? Where?
If I understand your quest rightly: I assume because of the high voltage it connects via air.
Be very careful with high voltage and make sure you take the time to read the basics of electronics and the precautions of high voltage. This is a simple circuit that, quite frankly, is baby stuff to us electronics and high voltage hobbyists, but can be dangerous to you and your surroundings. The EMI they create can damage sensitive electronics like pacemeakers, implanted defibrilators, and cranial implants like the ones for control of Parkinson's disease and chronic migranes, as well as computers, CRT and flat screen TV's, stereo systems, etc. The plasma discharge is high frequency and voltage but low current, so it can't stop your heart because of skin effect, but it can burn you with burns that may not hurt bad at first, so you don't realize how bad it has burned you until later. Megahertz range high voltage can give you RF burns that don't behave like thermal burns, (severity and depth dependant on temperature and time duration of exposure,) but instead can burn straight through to the bone and cause deep tissue and nerve damage, even bone marrow damage. RF can also cause cataracts in the eyes and cause genetic damage, and later birth defects, in the eggs in a female's ovaries. Like I said though, this is intro to high voltage, baby stuff, but if you move on to flyback transformers, ignition coils, and true tesla coils powered by neon sign transformers and microwave oven transformers, you can really hurt yourself. So know what your doing before trying, and always respect high voltage or it'll bite you.
Thank you sir

Where did you connect the black wire to. And what voltage are you inputting
Black wire is connected to the third pin (emitter) of the transistor. And supply voltage is around 12v
Good idea
I think blue is your favorite color 😊
