You might just make the best light saber noises I've ever heard lol

"It's pretty shit but it's working." - Sums up most of the things that I tinker together... .

Finally a KZfaqr who can solder properly.

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.

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!

Pretty cool. Light saber sounds are top notch...

"its pretty shit" had me crying lol...great vid btw

Wow. I'm watching tesla coil videos because my son wants to make one.

Great job! On the build AND the video. Subscribed.

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.

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.

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.

Great vid, mate! Thank you!

Bom experimento. Boa demonstração! Rio de Janeiro Brasil

Very nice video good explanation and time build thanks for the effort

Adding a tuning capacitor at the end of the wire will give better results as it tunes the oscillator and store energy

15:51 "Our Coroner is coronering" lol

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?

It looks good for a beginner project

"It's pretty shit but it's working!" Aussie saying! ;-)

Very useful thanks for sharing

Great video! Could I use a 16V - 0.6A power source?

Very good job! You should turn off all lights so we can see it well in the dark! Please make another video! Best regards

try adding a top load ( some tin foil crumpled up into a ball ontop) and touch the end wire there to it it does wonders

the year is 2020 and we are now afraid of the corona

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.

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.

Excellent and clear English lol, thank you very much from Belgium

cool toy. thanks for sharing

to achieve better results you SHALL tune ro quarter wave antenna. with such dimensions you can reach 1meter sparks

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.

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?

Awesome!

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!

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.

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

Beautiful xenon tube, I want it!! do you have a link for it?

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 ?

thanks bro!!

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!

mr.tesla was a genius!!

Lucky you, my 9$ ebay kit didn't come with thermal paste or a schematic/picture. Thanks for the vid!

hi which adapter do you recommend or were can I buy one cheap, OR any household item that i can borrow from? thanks a lot

do u thiunk you can improve the sound some how with a dome ontop?

Hi! I buy from banggood the same kit.After the assembly, the 2 leds are flashing, but nothing else happens. I do anything wrong;

ultra bright LEDs for power indicators are worse than .. something pretty bad.

Hello! Great video. In my case only the Red Led lights on, and no spark appear... What could be wrong?

Nice

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.

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.

Should've bought this, Electroboom!

Could you make an instructing video on how to assemble?

i want to add a variable capacitor and a momentary push button and make a little synth out of it! this is interesting...

nice video! could you link the eBay site you bought it from?

what model of iron you are using? also bought it at gearbest?

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 :(

For the LEDs and compositors is the short wire negative?

16:39 Where that sound came from Sir? What an interesting video!

Is it still working? Is the transistor BD243 gets pretty hot?

I have one of these im trying to learn soldering where do i get real instructions?

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..

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?

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

how would it play some MIDI-songs? :)

Any idea what the red LED is for? Mine isn't lighting up but the blue one is. I don't get a corona but it lights up a florescent light.

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

Hi. I have assembled mine buy it does not work. For starters Led 1 is not turning on. Ive checked polarity but no rwukts. Any idea?

I couldn’t get mine to work, but didn’t have thermal grease, could that be the problem?

I Like you man, i'm gonna keep my eye on you man

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

I wouldn't think that a circuit this simple couldn't work... yet it doesn't. Red LED lights up ever so barely and no HV at all. Coil ground is OK, scraped the insulation, joint is all right. Maybe that's got to do with swapping the BD243 to an MJE13007-2? :D (slightly more beefy, thought it couldn't hurt)

How big would one of those have to be to power a house and garage?

Where to find the AC adaptor my adpter pin is no fiiting in the power jack

This things nuts. Hopefully it works more than 10 minutes

did it come with its own powe supply cord

And just think, Tesla designed his system to not radiate out into space but to use a ground connection For power

Whats the solder point inside the coil for

I got 1 whatdid for 3 week put it together and I don't work the LEDs tune​ on but no spark

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

do you have the link on ebay for this item

you have to let it arc for the music im curious what it does

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.

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.

i superglued a 40mm fan on the heatsinks, but this thing really isnt great its spark is tiny on mine

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

Can you also light op a led

genial

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?

Question, do the transistor heatsink get really hot on yours?

ive bought this kit twice and ive had broken components twice, think I should get a refund?

How many volts is the electrolityc 10 uf microfards

Where is the sound generated from when using the coil?

Can the blue capacitor's prongs be placed in a different way? I think I placed mine wrong. My LED 2 doesnt light up.

*_ELECTROBOOM TRIGGERED_*

I bought this just now.

What would happen if you got a phone camera too close and the spark hit the lens?

what did that tube come out of

Does this come with a power supply?

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.

Can u please tell me the link u bought the CCFL tube in Ebay as I am not getting any results when I search CCFL tube
