If you want to get serious you`ll at least need a flyback transformer from and old TV. That with the correct sized tubes to wind the air cored coil(s), caps, cables, mounting board, mains cable and a few other things. You do really need to stand back though. My last effort had plasma sparks up to 3 feet long. Then the neighbours complained about interference up to 4 houses away. No sense of fun or adventure. Mind you, if you stood too close that one would kill dead easy. Made your hair start to stand up from about 8 - 10 feet away.
I have three of those coils as they are really fun to make and really cheap. Their sound quality isn’t too good but I think it is cool to listen to music with plasma from a Tesla coil!
Thanks for this video, it helped me put mine together. Despite the Chinese instructions, the circuit board was well marked, but your explanation of how the Slayer Exciter works let me figure out a few minor adjustments I needed and where a bad solder joint I'd made was. Oh, and what the damn neon lamp was for, so I didn't go nuts trying to figure out where it went.
@@firemyster4707you can just use any old random 15-24v DC power supply. I have a music studio so I have many power supplies to just randomly choose from.
practice is the best teacher. You will get a feel for it. Main thing is hot iron. Heat the area to be soldered with the iron Apply solder and watch how it behaves. It should immediately flow around the area. If it sputters, bunches up and whatnot, the area isn't hot enough. Once it flows, pull the solder away, then the tip. In general aside from a short, even a bad solder joint will las long enough to work.
For anyone who can't get it to work, specifically, those that are seeing only LED2 turn on, try replacing the red primary coil with a wire with fewer turns. Newer versions of this kit say to use 2-3 turns, but try trimming it down from 3 to 2, and if that still doesn't work, from 2 to 1 turn. I had 3 turns, then cut it down to 1 turn and it worked with no other changes.
Well done. No need to keep safe distance, it's fun to touch, briefly. Keep your hand on it for too long and you'll find a small hole burnt in your finger :-) doesn't hurt much though, and it's fun.
Mine too doesn't work. It barely makes the NE2 glow and even then it has to be touching the middle of the coil. The red LED doesn't light. And yes I've tried another red LED touching the terminals with the polarity the other way around and no dice. The heat sinks get hot 200 mA at 18V And I measured 5.6 MHz.
Both of my LED's turn on a second after I plug the unit in. I didn't notice any reason for having two LED's other than to give you a visual que that the unit is on...
Mine doesn't light either... I also don't get a corona... AND... it doesn't light anything either. I check all the connections. Ohh well. It was cheap.
Did you make sure to get the two transistors in the correct locations? They are different part numbers and need to be installed correctly. Other than that, maybe test the transistors to make sure yours are working ok.
Thanks MFM. I've ordered another one. If it works, than I'll buy new transistors. I'll buy new, because I don't think the FET can be easily tested for its "proper" functioning.
Your digital display has a heater wire from left to right to heat the gas and aet the gas ionize at a lower voltage during normal operation. If you have a display wired properly, get your eye accustomed to the dark and look at the center of the digits with as few digits lit up as possible. You'll see a faint red glow from the wire across the display from left to right.
Hi, I ordered the kit, which came without circuit diagram, so I have put it together using the pictures. With the coil itself: does it matter which way up it goes ? Also, with one end, it’s just left in the air above, and the other end, is it soldered to the one hole placed at the centre of where the tube sits ?
It doesn't matter which way up the coil goes, but the hole you use is the small one near the corner, just outside the circle markings for the coil location. You'll see me install it at the 6:50 mark in the video.
Open your web browser and type in "ebay" then your country code. Then there is a place at the top of the page called a "search box". Type in there "Tesla Coil" and click the button. When the HUNDREDS of identical listings show, find the Filter and Sort them by Price. Now you know, so you won't need to ask next time.
Great man, you're so polite.. You know it's hard to know what you get with these ass cheap listings, and NFM found one that (kinda) works, so I wanted to buy the one they tried out ;-)
Mine is not working too. Looks that the enamel has not been correctly removed. I used however a lighter to burn the tips of the coil wire. At the end, yes the white LED is not lightning up... and I cannot see any oscillation into the primary by using an oscilloscope. Is that the primary coil wire soldered in the right direction?? I used to do exactly like the photography as I cannot read Chinese.
Any idea how to trouble shoot this thing? The instructions on the one I got which look exactly like yours said the + and - terminals on one of the LED's was reversed. So, I did correct that after testing it with a multimeter and seeing it light up when the correct electrode colors were matched. However, it still isn't turning on with about 5 different power supply tries, everything from 5V 2A to 20V 1A. Unfortunatley I don't have a perfect 15-24V and 2 A DC supply. Either the voltage is a little low and amperage high, or voltage is high and amperage is slightly low. I'd figure at least the LED's would light up. I don't know if the 1 wrap wire needs to be in a certain direction or perfectly close together. I've checked all solder joints, ran through it with connectvity and hear the buzzing noise on my multimeter, just can't get the dang thing to power on at all!
Thank you NFM for putting this video up. Very useful. I have one also, but it barely makes the NE2 glow and even then it has to be touching the middle of the coil. And Like Shaun Thomson, the red LED doesn't light. Power drain is 300 mA at 24V input. Measured RF is 5.6 MHz. What frequency does yours come to?
Solution: Use a very hot soldering iron on the insulation of the enameled wire of the coil. That is the grounded end of the coil and so you can't expect the voltage to break through the insulation.
BURN the enamel insulation with a match or cigarette lighter, not a soldering iron (that is wrong way). Then sand the wire slightly, clean it, add flux and THEN solder it in.
Hey fellow Aussie, best video about this thing! Any idea what the pad inside the secondary coil is for? Did you use it? What about the pad between the FET and its heatsink?
Hi. I have bought the same stuff but I have a problem. The schmatic show 4 resistors with different values, while on the component list they are placed in different places i.e the R4 in the digram is the R2 in the list. Could you tell me how have I to place the resistor in the right place? Thanj you
Question. I assembled this thing but I don't think it's working. Is it bad that I cut the very top of the copper wire that sparks? The sticker was bugging me I couldn't rip it off so I just cut a quarter inch off the top.
Pier Aisa A little knowledge is a dangerous thing. Have you the slightest idea just how long is a quarter wave at the frequency of that great big tuning coil? Where would you put it?
I got the same tesla coil off of ebay and it works great, but 5min ago I touched something near the audio jack and I got a shock, maybe electrical maybe heat, do you know what shocked me? It was a very different feeling compared to the tesla coil electric arc shock.
One aspect of English from the Isles that didn't make it across the Atlantic is appending the 'r' sound in between words when the first ends in a vowel sound and the second begins in one. Many who grow up doing it don't even hear it.
I wonder how that would sound if you ditch C1, J1 and possibly C2, then connect gate of Q1 to an interrupter or other generator like that. Since the cost of these is next to nothing (seen for £3.80 on ebay) I guess I'll buy one and see.
Good reference video. I'm not an electrician and have some questions... I used a 24v 500mA wall wart and it worked, even though it was supposed to be a minimum of 2A! How hot did your heat sinks get? Mine could burn my skin within 3 minutes, they where so hot! How long did you let yours run without restarting? How long without a fan do you think the tesla coil can run, before it fails? thanks.
Yeah, the heat sinks do get really hot! I think the circuit is as bare bones as possible and so won't really like long operation..... I'm not sure how long it will run with a fan, but as long as the heat sinks are cool, I guess it should run indefinitely.
I bought a 12v 30mm fan and rigged it directly, attached and covering, the inside of both heat sinks. So now I had to order some O rings, because of the noise of the vibration it makes, is conflicting with the sound of the tesla, while playing music. But this stabilized the heat problem, so far, where I had it on for 10 minutes. I didn't want to take a chance on burning it out yet, until I play my guitar through it...
No Red LED . . . Make sure to use a very hot soldering iron on the insulation of the enameled wire of the coil. That is the grounded end of the coil and so you can't expect the voltage to break through the insulation.
Aspirin is the best solution for removing the enamel. Just put the wire on the tablet and warm it by mean of the soldering iron. The acid removes instantly the enamel.
I cant tell apart the 2k resistor from the 10k also witch way should it be facing. witch way should the capacitors be facing. where dose the coil connect I see two holes one on top and one in the middle of the coil
Arturo Nunez resistors don't have any specific direction they need to face. Electrolytic capacitors do though (the black cylindrical things that came with the kit)
Please help me. When I plug it in with a 24v 1A adapter only the blue LED turns on. It doesn't make sparks or turns on the neon light. It does nothing. I burnt the coating on the secondary ground connection, checked the polarity on everything and checked the MOSFETs. Everything is in its place but it doesn't work. What could be the problem?
I figured out the answers to my questions the only thing now is there is 3 unused holes 2 all the way to the left with plus minus sign next to them and one hole right under the coil is this supposed to be like this
Don't worry about the 2 holes near the input "jack". They are another way to supply voltage. An an Electronic & Electrical Engineer, I am confused about the pad inside the coil?????
I've gotten 3 of these things from 3 different companies and no matter what I do I cannot get the to run. 0.3 A running, no corona, no red light, only about 0.63V across the LED. The 350t coil shows continuity albeit with some resistance. The resistance was consistent across all 3 coils. What the heck is going on. :(
What glue did you use to glur e the coil on with,is it super glue or something else,my kit didn't come with any paper work ,if possible ,could you send me a copy I can print out,also mine didn't come with any thermal paste,but I have plenty,your seem to come with more stuff ,I glad you did a video ,it should be helpful to your fans ,I hope next time you will video at normal speed .great stuff
I have made mine but it doesn't play music and when I connect it to my phone it does random things(it's not near the coil) by itself, any ideas how to fix?
mine came with a glue stick that I assumed was for soldering the parts together, however mine isn't working.. should I have used other material to solder?
I'm not sure about the glue stick? You mean the white paste? That would be used between the transistors and heat sinks. I used my own solder to make the kit.
If you have to ask this, I think you shouldn't play with anything that creates sparks. The current rating on a power supply is the maximum current it *can* deliver, not the current it *does* deliver. You can use a 24V/1000A supply and it will still be fine.
He answered your question. A 3A psu i capable of delivering 3A at 100% load. It doesn't mean it delivers 3A. It doesn't matter if you hook this thing up to a 3A psu or a 1000A psu.
The LED's light up on mine, but that it... The soldering has been done right and the input voltage is 19V (which should be enough). I though the biggest issue was one of the legs missing threads, but it doesn't even seem to work :(
Very nice instruction, thank you. My question is.. will it seriously hurt if I touch that arc? But, at 15:43, it's not the Galaxy Note 4, it's the Note 3 xD (I've had the Note 4, tbh it was the best phone i've ever had, better than my actual Note8..)
I reckon it'll hurt a bit, but it won't kill you (I think... :) ) You're probably right re. the Note 3, it was a friends one I borrowed. I have a Note 9 now and I love it.
HI Everybody. I was wondering if a plasma ball/Tesla could be used to disable the corona virus inside the lungs simply by holding a plasma ball near the lung/chest area front and back as the field seems to exist quite a distance. Viruses are quite fragile and a strong em field could disable it's reproductive ability and the body could clear it like any other infection....
Glad I found your video. My Chinese is as poor as my Klingon so I could not read what the light was for. I left my soldering station on, not knowing where that light and final screw went! Now to find a powerful enough wall wart; and hot glue to heat up, to finish attaching the coil.
Hi, this is awesome! I have a question, where I can get that glowing tube you have on video (14 minutes and 17 seconds)? I made a same tesla coil and I want to buy that tube :) thanks a lot for reply
Hi! Some remarks (I hope). The printing of pins of FET is wrong: reversed. Please see 80NF70 pinout OR compare the schematic with PCB, where the "gate" is connected to Audio input (in reality the source - as on schematic). It does not make any problem if you build it, as you need to place it on heatsink, but maybe misleading if you want to debug.. Second. I would not recommend changing the coupling capacitor to 10uF as the arc is not capable to give bass sounds back clearly. It just distorts them ! Third, some facts with my measurements of four modules... The current consumption is about 0.6A (not affected by modulation). The resonance frequency is around 4.6Mhz but emits some electric noise up to 100MHz (checked with spectrum analyzer). The temperature of heatsink goes up to 70deg celsius in the first 5 minutes of operation..
NFM...Have you checked on what frequency this operates..Could somewhere from LONG wave to MEDIUM wave (AM band) The oscillator carrier could land on somebody's favo(u)rite AM station. The arcing tip could be producing "hash"... noise over a very wide band. The odd burst wouldn't be much of a problem but running continuously as a speaker could wipe out a large piece of band, giving the FCC or whoever is your local controlling body, plenty of time to trace you down..That's when the fun really starts!
You might just make the best light saber noises I've ever heard lol

soldering is real simple it’s not hard and not really hard to mess it up

The one turn coil looks higher because your coil is upside down comparing to the coil on the picture
ultra bright LEDs for power indicators are worse than .. something pretty bad.
@13:33 - Did you notice the corona's UV light was making the marks on the cutting pad glow?
Nah I didn't, good catch! Must be something like a phosphor in the pigment of the ink to make it brighter white that was reacting to the UV.
Great video! Could I use a 16V - 0.6A power source?
How big would one of those have to be to power a house and garage?
Adding a tuning capacitor at the end of the wire will give better results as it tunes the oscillator and store energy
Question, do the transistor heatsink get really hot on yours?
Yep, they do get very hot.
It really needs a bigger heat sink to run for long periods.
What would happen if you got a phone camera too close and the spark hit the lens?
Mine is not working too. Looks that the enamel has not been correctly removed. I used however a lighter to burn the tips of the coil wire.

I figured out the answers to my questions the only thing now is there is 3 unused holes 2 all the way to the left with plus minus sign next to them and one hole right under the coil is this supposed to be like this
Don't worry about the 2 holes near the input "jack". They are another way to supply voltage.
An an Electronic & Electrical Engineer, I am confused about the pad inside the coil?????
How do you tell which end of the coil is top and bottom?
From memory I think it is symmetrical so it doesn't matter.
@@NearFarMedia oh thank you
what model of iron you are using? also bought it at gearbest?
what is that lightning tube?and is that a dc current?thanks.
It's a cold cathode fluorescent tube.
I'm think the output is pulsed DC.
@@NearFarMedia thank you..
I've gotten 3 of these things from 3 different companies and no matter what I do I cannot get the to run. 0.3 A running, no corona, no red light, only about 0.63V across the LED. The 350t coil shows continuity albeit with some resistance. The resistance was consistent across all 3 coils. What the heck is going on. :(
Got one of these and it only lasted about a mi ute befour the transistors were really hot and it stopped working
Any ideas or was it just a crappy kit
Mine did not come with the white thermal grease for the transistors, so I added a little fan to cool it down, I won't use it for music anyway.
how do you identify the LED polarrity on an unmarked PCB board?
Easiest way would be to check the schematic or maybe it is marked on the board layout if it was provided.
What glue did you use to glur e the coil on with,is it super glue or something else,my kit didn't come with any paper work ,if possible ,could you send me a copy I can print out,also mine didn't come with any thermal paste,but I have plenty,your seem to come with more stuff ,I glad you did a video ,it should be helpful to your fans ,I hope next time you will video at normal speed .great stuff
I just used superglue.
Unfortunately I don't have the instructions anymore... Sorry!
I have made mine but it doesn't play music and when I connect it to my phone it does random things(it's not near the coil) by itself, any ideas how to fix?
mine came with a glue stick that I assumed was for soldering the parts together, however mine isn't working.. should I have used other material to solder?
I'm not sure about the glue stick? You mean the white paste? That would be used between the transistors and heat sinks.
I used my own solder to make the kit.
It's a "cutting mat".
what did that tube come out of
Beautiful xenon tube, I want it!! do you have a link for it?
What effect would a 3A supply cause? Would it heat up faster? I Have a 24V - 3A supply and I don't know if I should buy a new one.
If you have to ask this, I think you shouldn't play with anything that creates sparks. The current rating on a power supply is the maximum current it *can* deliver, not the current it *does* deliver. You can use a 24V/1000A supply and it will still be fine.
You still didn't answer my question though, what would happen?
Nothing.
He answered your question. A 3A psu i capable of delivering 3A at 100% load. It doesn't mean it delivers 3A. It doesn't matter if you hook this thing up to a 3A psu or a 1000A psu.
Well not nothing. It should work fine!
Does this come with a power supply?
Can you please use metric units?
You also use Volts, which is based on other metric units, please be consistent.
Learn to speak more than one units language. It's not difficult.
This things nuts. Hopefully it works more than 10 minutes
It works for about 20 seconds then cuts out. Gets suuuuper hot. Still worth for $5
Yeah, mine does too. It really needs a fan or much larger heat sink for continuous operation I think.
The LED's light up on mine, but that it... The soldering has been done right and the input voltage is 19V (which should be enough).
I though the biggest issue was one of the legs missing threads, but it doesn't even seem to work :(
Very nice instruction, thank you. My question is.. will it seriously hurt if I touch that arc?
But, at 15:43, it's not the Galaxy Note 4, it's the Note 3 xD
(I've had the Note 4, tbh it was the best phone i've ever had, better than my actual Note8..)
I reckon it'll hurt a bit, but it won't kill you (I think... :) )
You're probably right re. the Note 3, it was a friends one I borrowed.
I have a Note 9 now and I love it.
HI Everybody. I was wondering if a plasma ball/Tesla could be used to disable the corona virus inside the lungs simply by holding a plasma ball near the lung/chest area front and back as the field seems to exist quite a distance. Viruses are quite fragile and a strong em field could disable it's reproductive ability and the body could clear it like any other infection....
Is the corona discharge dangerous to touch?
Yep, it's plasma... Basically.
it'll burn you.
Glad I found your video. My Chinese is as poor as my Klingon so I could not read what the light was for. I left my soldering station on, not knowing where that light and final screw went! Now to find a powerful enough wall wart; and hot glue to heat up, to finish attaching the coil.
have a link to the product?
Hi, this is awesome! I have a question, where I can get that glowing tube you have on video (14 minutes and 17 seconds)? I made a same tesla coil and I want to buy that tube :) thanks a lot for reply
Sairax Official It's just a cold cathode fluorescent tube. You can find them as the backlight in almost any non-LED backlit LCD screen.
Cool, thank you :)
Do you have to use the Grease or will it work/be safe without it?
Or an older scanner.
Hi! Some remarks (I hope). The printing of pins of FET is wrong: reversed. Please see 80NF70 pinout OR compare the schematic with PCB, where the "gate" is connected to Audio input (in reality the source - as on schematic). It does not make any problem if you build it, as you need to place it on heatsink, but maybe misleading if you want to debug..
Second. I would not recommend changing the coupling capacitor to 10uF as the arc is not capable to give bass sounds back clearly. It just distorts them !
Third, some facts with my measurements of four modules...
The current consumption is about 0.6A (not affected by modulation).
The resonance frequency is around 4.6Mhz but emits some electric noise up to 100MHz (checked with spectrum analyzer).
The temperature of heatsink goes up to 70deg celsius in the first 5 minutes of operation..
Thanks for the info!
Does it still work?
I got 1 whatdid for 3 week put it together and I don't work the LEDs tune on but no spark
Mine didn't work and I followed it to the letter
can i touch high voltage of this tesla coil with no electrocution ?
I don't think it will kill you, but it wouldn't be pleasant to touch so I would avoid touching any part of the circuit while it is turned on.
NFM...Have you checked on what frequency this operates..Could somewhere from LONG wave to MEDIUM wave (AM band) The oscillator carrier could land on somebody's favo(u)rite
AM station. The arcing tip could be producing "hash"... noise over a very wide band.
The odd burst wouldn't be much of a problem but running continuously as a speaker could wipe out a large piece of band, giving the FCC or whoever is your local controlling body, plenty of time to trace you down..That's when the fun really starts!
