How to make Tesla Coil
How to make Tesla Coil. Simple solid state Tesla coil also called slayer exciter circuit (A Slayer Exciter is an air-cored transformer that steps up a very low DC voltage to a very high AC voltage) Its is a simplest Tesla Coil and class 8th to above students can build under parents or teacher supervision.
What is Tesla Coil? A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high-voltage with low-current and high frequency of alternating-current electricity. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits. Read more.

Will my tesla coil still work without a heat sink and a capacitor? Please reply ASAP. Cause in some videos I noticed no use of capacitor just LED, resistor and transistor
capacitor protects the transistor to burn
I have been trying for so many days my tesla coil wont produce wireless spark pls help plssss
i use 30 guage wire with 700 secondary turn but its not working what can i do for that
can you share your project photos?
yes
Hello I posted the picture please help me.
: o
1st try to invert 2nd coil connection and can you tell what is size and turns of primary coil?
The primary coil is 56 cm and have to loops around the copper tube.
your primary coil gauge seems thick it should be 30 gauge and turns should be more then 200
the primary coil is 56 cm (red wire 300v – 20 ga) and have two loops around the cooper. the second coil is cooper 24 awg.
we need change the first coil ?
what about intersection of first coil to the transistor circuit?
The tube is 2.5 of diameter and 10 centimeters tall the tube and and only put 7.5 tall of copper.
I replied already what do I do now.
I tried to invert the 2nd coil connection but did not work.
Where are photos?

I also suggest about 2nd coil do not use this red plastic coated wire use pure copper 26 gauge wire
I used 24 gauge copper wire.
I recommend please use 26 to 30 gauge copper wire. And also used 24 or 26 gauge copper wire for secondary coil
thanks you for your help it works. : )
Welcome
Please can some one reply
My Tesla coil does not wont to turn on. But I am doing a different model of a Tesla coil it is for my science fair project please can you help me.
Can you share your project photos
Can you please help me I need it for tomorrow.
🙂
Please help me.
Help me please, please. : )
Correct me if I am wrong, but the pictorial diagram is not correct. It appears that the LED is not wired in properly. It shows the Anode connected to the Base when it should be on the Emitter, and the Cathode is connected to the Emitter when it should be on Base. https://uploads.disquscdn.com/images/68712bf1d28c81d5a361a638433b927a93ed5b888ca3a39ac051bc016c4029a2.jpg
thank you for mention
and let me confirm
pls help me. I tried doing the same thing the battery heats up and yet theres no flow of electricity within the board. Pls help me. Its for my science project
can you share your project picture?
Here it is, pls help mee https://uploads.disquscdn.com/images/c44bd7e37afdec3ba9b4fca84e047c20fd97fe6114f8efec4ddb716ad86da817.jpg
Oh your battery connection is wrong please read board connection diagram
Still not working, i tried to change My circuit here it looks.
And my copper wire for secondary coil is 28G
primary coil is 22G.
I use npn transistor.
9 volts battery huhuhu. Whats wrong https://uploads.disquscdn.com/images/78c5e8235b92cf75838b65bde8838d32b244309cdd93d803c746f18488bbd658.jpg
Your battery is shorted out to itself. Put the black wire into the other track. That’s why it is getting hot. Here is an image showing how the tracks work on a breadboard. Keep in mind that some breadboards are different and will have a break in the center for the blue and red strips in the image. Another problem I have spotted is that your battery is not part of the circuit. https://uploads.disquscdn.com/images/b6d32e22e5f5f0a5c3533efa3448e9b7e43ab913e51eac2f00757c0c37ae2eca.png
Ahh my battery connection is wrong. I’ll try again. Thank you
Did you get the tesla coil to work?
Yes it works. But i used your other video. Instead of breadboard i use the soldering technique https://uploads.disquscdn.com/images/e319cf11417e45483268f5e40fcfacf2d89343ab8f9960018dcaf6997c40c28d.jpg
Can i use othee bulbs other than cfl? What king and how many watts
No you don’t use
Only cfl bulbs? But can it exceed in more than 5 watss?
any of cfl can work what ever its 5 watt or 100 watt
any of cfl can work what ever its 5 watt or 100 watt
why only CFL ??
I want to innovate my tesla coil. I want to enlarge my secondary coil about 560 turns. How many turns should be my primary coil. And will it be okay to use the same transistor and resistor? Will it not heat up? Pls reply immediately. Thank you
And will my tesla improve if i put a top load, pingpong ball covered in aluminum foil ?
You should do experiment and share its results with us

what size of you copper wire?
28 to 30 gauge is good for this project
hey.I made a tesla coil that you have talked about.My Led is glowing and When i touch the coil it turns off.But when i took my energy light closer to Coil,it doesnt glowing.I inverted the primary coil,but led doesnt glowing means my past circuit is perfect.So what should i do know?I need to fixz it before 28th January.Pls Help.
Hey, i’ve made a same tesla coil with all the requirements you have talked about but the problem is, when the battery is connected the LED glows up and the salyer doesn’t works the transistor heats a bit of too. I tried inverting the primary coil but the LED glows continuously independent of everything. Please help me, as it is mine physics project i need to work it out asap…. https://uploads.disquscdn.com/images/9b295e1d0f48d7df6bdda86fec076eb38a599738a4fc5a83ac52cf1d0f2eac63.jpg
can you confirm me about your copper wire is it enamel coated copper wire ? in picture 2nd coil doesn’t look
https://uploads.disquscdn.com/images/4a0c87652fb9ecb5ae97734b004bf0f700dace3e9c169b404f293e2e82b9f105.jpg https://uploads.disquscdn.com/images/29f93a42c391efe9cfae72b532649be3f275c362ec24606a5d211c8a2df81ff0.jpg https://uploads.disquscdn.com/images/e8a767e9e3e76bdf99e83f549b7a2e91597571015958530206348f9f61a5f5b7.jpg https://uploads.disquscdn.com/images/2ff58866078a94968a7d2fd1c7e387599532a04ac56c48110a8ad0578fc16071.jpg
Salam Aleykum, Could you explain me where I made a mistake. It does not work. I used transistor TIP41c , 22K resistor, on-off-switch, 26 awg(0.4mm) for secondary coil, 18 awg(1mm) for primary coil, approximately 200 turns for secondary coil and 2 turns for primary coil. Also I checked other transistors and resistors, they did not work either. What is wrong with this circuit? please help me. I think the problem is related to 18 awg (1mm) cable.
use enamel coated copper wire instead of this 2nd coil wire
Can anyone help me about this project as I messaged yesterday also but I didn’t got any reply that what gauge of copper wire I should use for secondary coil.
Try to replace red wire with 26 gauge copper wire then tell us the results.
Aoa, Hi sir I made this project all properly used 2N2222A transistor, 29 k resistor, 27 gauge copper wire and pvc pipe and also insulated wire also but it’s not making any out put. For power I used 9v battery and connector and 11w energy saver. Please help me as I need it as my science fair projects till 22 November 2016. Kindly help..
can you share your project photos here??

you project seems good can you tell me type of transistor you used? like pnp or npn?
what if I use 1400 primary, will it work?
yes its increase intensity
used 30 gauz wire 350 turns wire for the primary coil and 3 turns for the secondary .
it works but the brightness of the cfl bulbs and rods is not bright enough as showed on the video also the transistor is getting extremely hot. Sir please give a solution
please answer
what is the least amount of the turns of the pirmary coil
around 300 turns for primary and 3 for secondary coil
300 turns and 3 turns for 2nd coil
used 30 gauz wire 350 turns wire for the primary coil and 3 turns for the secondary .
it works but the brightness of the cfl bulbs and rods is not bright enough as showed on the video also the transistor is getting extremely hot. also cant take the cfl bulbs even 1 inch away from the coil also used a top load but nothing happened. Sir please give a solution
This is my circuit
where is photos of your project?
Used 30 gz with 300 turns, dia-0.50 inch, resistance 22k and transistor pn2222..bt its not working only the circuit led blinks when I touch the coil..i inverted the coil,battery bt no use…need help…
replace this transistor with other transistor
Dear Sir,
I have build a Tesla coil with 26 gauge copper wire,but when I connected to 9v battery the transistor become very hot and tesla coil is not working.I tried this project 7 times but it didn’t work and transistor become hot what was the mistake done by me please help me sir
second coil should be near to coil and its also looks thicker
Plz make a video telling what to do or what not to do in making tesla coil as all are getting troubled this request is from all the frnz waching your you tube channel plz
Do it definately
Plzplz plz plzplzplz plz plz plz plzplzplzplz plz plz
please watch our new video tutorial about this project
Dear Sir,
I have build this circuit, and it doesn’t work. In the photo you can see the general setup and the connection scheme. The secondary coil is 0.3mm (about 28 AWG) with about 280 turns. I tried with 2, 3, 5 and 6 turns for the primary coil, also reversing the connection in each case. Non of it worked. What could possibly be going wrong?
I see you primary coil’s 2nd terminal connected with other wire. it must be free and short in length
Thank you for your reply! The diode is actually a “normal” diode (1N4148) which I used instead of the LED. I replaced the diode by a LED. I also replaced the coil because the original one was on a massive wood cylinder, and I thought that maybe it should be a tube. The new one is a bit larger in diameter, on a plastic tube, with about 285 turns. The primary coil has now 4 turns. I shortened the 2nd terminal of the large coil. The primary coil is now clockwise, with the lower (the 1st) terminal
connected to the collector of the transistor. The secondary coil is
counterclockwise, with the 1st terminal connected to the base of the
transistor.
It works now, but only for a short time (a few seconds to half a minute), than the transistor burns. I do not know if its because of excessive voltage, excessive current, or whatsoever.
What could I do to keep the transistor from dying (apart from using one with higher voltage/current/power ratings)? Is it possible to use a darlington transistor?
Glad to know about its working
now you have to increase resistor Value or try to add additional transistor in parallel.
Hello,
I did both, increment the resistor value to 160k, and put a second transistor in parallel. The transistors still get very hot, but for now it is working all right. Thank you very much, I really appreciate your help! It is a great project! I was actually surprised how bright the lamp is glowing.
and i also observed you uses zener diode. try again without it
Salam. I have made this circuit. But it doesn’t work. I have tried both methods(with and without breadboard). The transistor gets very hot. But the led won’t light up neither will the coil work. Please help me sir. It’s urgent.
Please help me out. I really need this urgently. I will be most grateful. Thanks
Salam. Update: I can get the led to light up but the bulb doesn’t light up when I take it near the coil. I have almost 300 turns on the larger coil and 3 turns on the smaller one.
try to invert 2nd coil then check it
Thanks for replying :).
I’ve done that still doesnt work. I used a 26 guage copper wire for both coils. The larger coil has atleast 300 turns(maybe a little more). For the smaller coil I’ve tried with 2 or 3 turns one at a time. The pipe I used is of half inch diameter. Looks thinner than the one you used though. I ‘ll be waiting for your kind and helpful reply sir.
please try an other transistor some time it doesn’t work
please see this video https://www.youtube.com/watch?v=A8wwunusLW4
sir please can you tell the theory of operation of this project. i need the detail for my lab project.
my circuit is working but led id lighting and energy is not working . what can i do now ?
Please send its picture
what kind of wire can i use on primary & secendry ……
&
how many turn on primary & secendry ?
can i use 9 volts battery (not full charge )
Magnetuc copper wire guage 30 and more than 300 turns requires for primary and 3 to 4 for secondary
and do you need a light
why do you not have a capaciter or is that only for spark gaps
Capacitor is not required for this project
Can I use a kn2222a transistor?
Yes you can use
what are the dimensions of PVC pipe??
Dia is Half inch
what is the dimensions of PVC pipe??
capacitor for primary coil is not used why???
when the led is on, what does that mean???
Here are the pictures of my project. How can I fix this and make it work? Please as soon as possible!!!
Please can someone tell me what I did wrong or how I can fix this? Please!!!! I’m doing this for a project so please reply as soon as possible!!!
Your connection with Collector and emitter seems incorrect. please see this diagram which are shows collector base and emitter. see also this video it may be help you. https://www.youtube.com/watch?v=A8wwunusLW4
Sir, I have also made a tesla coil but it is not working, could you have a look and check what’s wrong in it please please please ? led is glowing but bulb is not lightning ?? I have attached pictures so that you could have a look
please watch new video tutorial i hope it will help you https://www.youtube.com/watch?v=A8wwunusLW4

Thanks for your valuable reply, I will definitely try out the simple version of that project. And sir did you saw the attached pictures of the project I made cause I wanted to know there I went wrong. Just a humble request to you that please check my model and tell any suitable solution to the problem.
Regards
ADITYA MITTAL
try to invert black wire if isn’t work try copper wire.
Hi one question, instead of magnet wire for the primary coil can it just be 22AWG hook up wire? I have magnet wire but other videos are saying to use hook up as the primary and magnet as the secondary.
were u able to make the coil work ??
Sir, I again tried it, the simpler version and it is not working ??AGAIN ??
Please have a look at the attached pictures.
negative terminal of battery connect with other side of transistor
Sir, I have also made a tesla coil but it is not working, could you have a look and check what’s wrong in it please please please ? led is glowing but bulb is not lightning ?? I have attached pictures so that you could have a look
Hey bro. Which bulb have u used in this project bcoz I m using CFL of 5 watt then it is not working and also the LED is blinking in inverted coil so pls suggest me
My email- yogendraslnk786@gmail. Com
any CFL bulb can work.
can you share your project picture?
hey, thank you so much for sharing your info.. I have a question tho, can I use thicker wire? 24 or 25 gauge? thank you brother!
yes you can use but intensity can’t change
very nice to see your detailed experiment and want to learn more from your experience.
please send ppt of simple tesla coil
pleas tell me as soon as possible….
any CFL bulb cab be use.
please can u tell me which type of bulb u used in the video to test the tesla coil (designed like CFL) ???
How much watt or volt it requires????
This is simple fluorescent bulb. This project required 9 volts and less than 1 amp.
thanks bro can i use 120v and 40watt CFL bulb????
Please tell me ….
for my project i used CT2N2222A transistor and 22k resistor and other things mentioned in the video
thanks abdul bhai if it not works i will ask the solution if u don’t have any problem….
Welcome
thanks…
i will try it and after i will answer u
again thanks….
Is it working?
i don’t have the bulb now i have to buy and try it …so…
Yes you can
I use 28 AWG wire and set up a same circuit as u mention but it’s not working not a single small LED is glow,can you help me why it is happen
Have you tried turning the coil ring upside down?
dear there is done a mistake by you habab the negative of the led is connected to emmiter but you say the positive is connected to emmiter revise the video and see, thanx
Please check you transistor and connections.
i`m sorry men, i forgot…. what does “copper wire 26 to 30 guag” mean??? it`s the gauge of the wire? how long is the tube or how many spins are in the coil?? i don`t speak english, jejejeje….. THANK’S
yes it’s gauge
you have to make 3 to 4 hundreds turns around the tube.
dear there is been done a mistake by you habab the negative of the led is connected to emmiter but you say the positive is connected to emmiter revise the video and see, thanx
nice… what’s the diameter of the tube?????
The diameter of tube is half inch
thanks @gianmarcopea:disqus the dia of tube is half inch
