Hey, as a kid who really wants to learn this and tinker, I was wondering if you could make an "intro to electronics" video where you go over the basics, since these kinds of things are hard when you don't know how or where to start. Thanks! Love what you're doing!
Watch GreatScott. I'm thirteen and he got me into electronics last year.
Nate Greatscott, electronics.stackexchange, buy books
ScreenGames yeah me too great scott is awesome (and i think he is German)
+RADOVSKY QUEK Yeah he is
Great Scott is the best!! :)
One of the simplest and most concise Tesla Coil builds I've found. Well done!
That's a very impressive output for its size
Edit: thanks a lot for the video, I managed to make it almost entirely out of reused parts. While I didn't get an output as high as yours, I did manage to get some arcs which is satisfying enough for now. And btw, you weren't joking when you said it gets hot, had to use a powerful computer fan with a microwave power transistor heatsink to keep the MOSFET somewhat cool. Very cool build, once again, thank you.
Sometimes I have no idea what you're talking about, but I love it nevertheless
+Brad G (thehmsbros) haha yeah I use a random word generator sometimes
Brad G I am in the second year of my apprenticeship as a mechatronics technician and i still don't know what he is talking about :D
This is electrical engineering. Anyone in who studies EE knows what he's talking about.
I'm 12 and I understand this stuff just fine, although, to be fair, I had no friends in third grade so I read a lot of books.
Okay ich habe diese spule
Thank you sooooo much for this video, I've tried building a tesla coil many times and ended up failing, but then I found your video, where you show how to build the easiest circuit and tesla coil i've ever seen. Thanks to your video, I have ended up with succsess.
Hey man love the video - I tried making a Tesla coil about a year ago with no luck and after some trial and error and messing around with the circuit u used I finally built a functioning coil - thanks again brother and keep up the great work!
Видео "Трансформатор TESLA": ruclips.net/p/PLlEX99xZE8qNc1MNp9EwjbeugLTRhr-9g
cant even watch a 2017 vid without corona in it 5:33
Brrruuuhhhh
Thanks. it worked very well with a 30v 10A variable power supply. At 30V, it draws about 1 to 2A current so the tiny 1k potentiometer (rated 0.5W?) gets too hot. I would replace it by a large wirewound potentiometer. The mosfet is cold at 30V. But when I replaced the discharge wire by a toroid top load, it stopped the corona discharge and blew the mosfet. So the point discharge wire is necessary for the Slayer exciter circuit.
These projects are always so cool! You make it look so easy!!!
this is the tesla coil i searched 1 year for thank you!!
I just stumbled across this video and had all the parts needed to make it. thank you for making a tutorial. I like high voltage.
Oh man I was so in awe by the light bulb that when the cap popped I almost shit myself.
Lol listen at half speed everyone it's hilarious. He sounds all drunk
I know what you are talking about and I like the way you simplified things without disregarding safety.
This man is a genius
Amazing! So intelligent yet simple. Stuff that could have been done with those old Radio Shack electronics kits!
Rip radio shack
you speak really fast, are you a rapper?
mirror speaker 1 he knows we're really busy and haven't got much time to watch videos!! :-)
for me he is talking kinda slow.
The Terrarian you are extra fast
Hes too well educated to be a rapper.
i dont really think that it is fast, i think other youtubers are slow for me personaly it is normal speed
I like the rapid pace
Hey, again. For your big tesla coil, could you try to do a single transistor SSTC with a interrupter/ audio modulator? MatesHV2 made a good one and posted a schematic.
I think that if you have a larger top load it will generate a larger visible plasma thing because the large object will become magnetic while it's on, thus increasing the range
Sawyer H Actually, yeah it would increase the range, but the arcs would no longer be visible without drawing then out with a piece of metal.
Dude. You're Almost at 100,000 Subscribers. Congrats. You Really Deserve It. How Do You Manage Your Time So Well?
I made same circuit 3weeks ago with 1260turns on secondary ! 3cm spark !
now im working on vacuum tube tesla coil ,811a tube
also, you may want to layer your secondary coil with varnish or lacquer. This protects the wire from damage and the wires slowly loosening from seasonal temperature change.
Subscribed for this and the Microwave Gun.
thank you, that is exactly what I have been trying to build!
Tesla coil instructions r g8ly appreciated👌🍻
the perfect example of how to make a Tesla coil thank you very very much
How many amps does it take at 30 volts?
Sebastian Bosch 10,000
I would love some kind of intro to circuit diagrams, or something similar!
This is a cute little coil, nice! As a suggestion, you might try adding a high-power zener diode across the mosfet gate and source to limit the voltage, rather than just a resistor network, although i suspect you'll still need a relatively low-value resistor from VCC to the gate for bias, as with a vacuum tube tesla coil.
Liam Taylor
How about addinh some flyback diode in parallel of primary coil?
@@franklopez9903 Great idea the transistor will be protected by the back EMF of the coil
Thank you Keystone science for inspiring me to build this project, I actually have already make this circuit using IRFP 260N MOSFET, it works great, but even greater when you connect the source of the MOSFET to earth ground, i thought this because when Iam building a tesla coil with spark gaps, you need to connect the bottom end of the secondary coil to earth ground to close the circuits, and so I applied that to a solid state one , and it also works great.
That heatsink is a monster.
I love you you make cool stuff and you use a fountain pen
can some one explain tot me how this circuit works? i understand how a regular slayer exiter circuit works but i dont get how he is making it work without a diode.
What power supply I can use as I don't have a variable power supply??? What Volt and Ampere should be ??
The best SSCT I have seen. It works perfectly and its very powerfull. My coil has 1000 turns. But I think I have fried my router and it was in other room and 5 or 6 meters away!!
I really like your content, and you explain everything pretty well, but could you consider explaining how to determine the exact values of components? I understand basic stuff like ohms law, but with inductors and capacitors i have some trouble figuring it out
I love your videos keystone, it has become like a hobby for me ... electrical engineering science is the best!
Hi could you do a video on boost converters, and also how to fix the shorting problem, like I put a wire across my output and the boost converter turns off, and so I'm wondering how I can power a slayer excited when my boost converter keep turning off or flashing
Keystone Science Guy: This is the circuit we're going to be using today.
Me looking at the paper: Yes, but sir...I don't know how to do Rocket Science.
@Urbexx Jeremy Then why didn't I understand a word he said when I'm smarter than 90% of the people I know.
@Urbexx Jeremy and don't act like you're the smartest person on Planet Earth... It's Pretentious and Arrogant.
"Then why didn't I understand a word he said when I'm smarter than 90% of the people I know." "and don't act like you're the smartest person on Planet Earth... It's Pretentious and Arrogant."
Could I use a 2-3 cm tube for my primary
cool videos man, i really appreciate the fact that you walked us through the circuit making.
Your channel has blown up fast congrats love your videos
Great work, nearly at 100k, hope you get the play button soon, you definitely deserve it!: )
cool build
You weren’t kidding when you said the transistor was going to get hot, I used a relatively big heat sink, powered the circuit with 24v and after a minute I smelled burning, touched it and it really burned my skin.
I had to adapt an old computer Pentium 4 heatsink, and it still gets quite warm with that huge surface area
Great video! I'm not an electric engineer but I think that you should mark "ground" as "GND", no "V-". I'm not trying to pick holes but it makes thinls a little confusing. Nevertheless nice clip!
Maybe you are right. I'm familiar with "V-" standing for supply which is symmetrical to GND. But as you wrote - this circuit is not grounded so it is not the issue.
ODPOWIEDZ
you should consider doing a video on the basics of circuits and what the parts do to help aspiring scientists like myself, great vid keep it up :)
I have tried this 'OSAM' circuit with IRFZ44N mosfet and it really worked for a few seconds and then blasted like a fuse, even though I was using a heatsink. Then I tried it with HRF3205 and it didn't work but heated up. After that I used another mosfet which is IRF540 and it also didn't work. In my opinion this circuit works best with IRFP260N mosfet.....
this is a slick video, glad to finally see it
this is what i waiting for.. a powerful circuit for tesla coil.... awsome boy keep on work !!!!!
I have questions-1. You used 50 Ohms resistor which seems rather very big and thick. What is the power handling rate for R1 you used?
2. The mosfet you used with ratings 200V and probably 50A continuous drain current. I have Power MOSFET of 200V,8A; 200V,18A; 50V,55A; and 60V,110A. What is the exact criteria for you to choose what MOSFET you are going to use? Is it voltage or current? If current, then what is the maximum current handling capability for jumper wires, primary windings and secondary windings?
3. What is the maximum current rush, voltage output and if I use battery of 12V,7.5AHC, two of them connected in parallel, how long does they gonna last if remain connected?
Other than this, it's fantastic idea.
Awesome instructional! Does the gauge of the primary coil wire matter? I am using 22 AWG for the primary and 30 AWG for the secondary. Would that suffice? I'm also using an IRFP460 for future scaling. You should see the size of the heatsink I've got for that MOSFET.
Hello there. Have you made the circuit with IRFP460 because I currently only have 460 and I want to know if it works!?
there are many circuits that uses irf460 mosfet, in fact it is mostly recommended because of its high ratings@@yiannisyiannis
Just wanted to say that I think Your awesome ... and wanted to Thankyou for sharing all your knowledge. I love your quirky personality, it makes your videos fun and the comical side makes you even better to watch you are giving science a new age twist (simply by being yourself) 😁 and I feel this brings people to the subject of science who would of been more likely to bypass science thinking they lack any interest in it.. but you sir I am sure have turned many heads and started them as heads thinking science and that's to be commended so thankyou for all your work and all you will continue to do just no it doesn't go unappreciated ... keep up the good work Tesla would be proud ppl like you keeping the energy of his essence alive Love and light 😇
Great work and solid explanation, as always.
+Tommy Callaway thank you tommy!
Cool fountain pen!
It's funny when he's like 'the capacitors won't blow up hopefully' xD
fountain pen == subscribed :D great video man!
Awesome video dude! Will bring this to the desk of elementary students I teach, but with battery 👍😁
Im having trouble getting this circuit to work... I have used all the right components including the IRFP260 mosfet, the 100watt 50 ohm resistor, and 2 0.47uF mkp capacitors but all that happens is the transistor fries... any things I can take a look at to get this working or get in contact with you somehow?
What voltage are you using in my case this circuit only works above 18v
nice videos man keep up the good work
+kamakazi ({PoRn-HuB}) thanks!
Mate I just listen coz I got no idea what you are saying,but it sounds legit...and very cool.
Suggestion please could you show us how to make a flux capacitor,,?
Hahaha sorry dude but you lost me. I'm a chemist but still love the videos :)
i know a lot of people complained about you talking too fast, that never bothered me before, but its good to see you slow it down a bit, i wish you and your channel the best, really enjoy your content. btw: do you call your channel "keystone science" because you are in Pennsylvania, because of the "keystone state" just curious, i live in PA. anyway, good work, love the channel, keep up the good work.
Can u make a video or several videos where u explain every electrical component like capacitors,transistor,resistors etc .Explaining how do they work and when do you need them in your circuits.
look up the channel GreatScott! he has a set of videos explaining them.
This was awesome, and I'm SO looking forward to your video on how to make a musical one... I've been wanting to do that for years.
Believe it or not I made it !! Works fine but the power supply keeps over heating !! Using an adopter with out up of 24V and 16VA.
After three days of troubleshooting, I finally got it to work! I had the drain and source swapped around on the MOSFET and in addition the primary was at the very bottom of the secondary. Push it up a little bit. Play around with the height of the primary. Also... Even if the primary has a sufficient coating on it, add more. I have a regular wire and it still managed to arc through the insulation. Spray the secondary with polyurethane or cover it up with electrical tape. Best of luck, people!
My TV is acting funny when I play around with the arc using my fingers. The TV will suddenly change inputs. It does this reliably. I can't figure it out.
I like it very much.. the parts are easily available and can build it easily.... awesome.
I saw that there was a heatsink use dso I just wanted to ask that is the fan in a heatsink compulsory to use ?
Would u mind explaining what is the use of the capacitor in the circuit??
and u r using the voltage divider because the mosfet has a gate-drain capacitance right?so the feedback from the secondary is just enough to change the voltage at gate betwwen its cutoff and saturated state??
it wood be cool to see you make or mod a plasma ball
You're talented man
cool stuff man
I noticed you only used one turn for the primary coil, is there a reason for that? It looked like your larger Tesla coil had more turns for the primary.
I made this Tesla Coil very impressed with the results,
3.2 cm diameter PVC tube
1523 turns of 0.315 magnetic wire Secondary coil
2.7 turns of 2mm single core earth wire Primary Coil
IRFP260N Power Mosfet
2x 0.47uf 275Vac class X2 anti rfi capacitor
68 Ohm 1/2 Watt Resistor
1k potentiometer
Power source 19V 3.2A Laptop Charger
Home built Variable voltage boost driver delivering 24.1V to 35.6V
With the boost driver attached this coil outputs 514 Volts at the secondary coil @ 29.8 Volts input.
Does it make a sparks?
Please if you dont mind if i get your email? Or any social media account?
@@user-se2gd2ib6y yes Helena it does produce 1cm sparks from a needle that is electrically connected to the topload
@@MrCareer707 can you send me the diagram?
@@user-se2gd2ib6y it's the same schematic as what is contained within this video, if you have the components that I have listed, the correct thickness of wire as I've included above and put this together according to the video schematic and the building of this circuit by the host, it should work,
@@MrCareer707 please can you send me picture of your circuit? I need to make it by this weekend :(
Whats the max voltage I can put into this?
Depends on the transistor used. IRFP260N has a maximum drain/source voltage (Vds,) of 200V, but the Slayer Exciter, which is really what this is, has a very inefficient operation which is Class A and nowhere near as efficient as Class C, D, or E, which is why so much power is wasted as heat, because the transistor is operating in its active region all the time making a sinusoidal waveform rather than fully on or fully off. So, you wouldn't be able to operate this, with the IRFP260N, at anywhere close to 200V. Pretty much, you would be doing well if you could operate it with 100VDC. Safely, I wouldn't go much over 60-80VDC unless you have plenty of 260N's on hand. Now if you want more than that, you could use the IRFP460N that has a Vds of 500VDC. It has a slightly higher on resistance (Rdson,) of 0.24 ohms, as opposed to IRFP260N's 0.055 ohms, but that should be ok. You probably could get it to run at rectified US 120V mains, but don't know about rectified 230V mains. You could always try it and see. If you're using other transistor types then you're going to want as high of a drain/source voltage (Vds,) and continuous drain current (Id,) as you can get, and as low of an on resistance (Rdson,) as possible. For example, if using IRF510, I wouldn't go over 48VDC. It has a Vds of 100VDC, but it's best not to go over 1/2 Vds.
My Winter project. I want a mini one
Love all your videos
+Treda Coolpants thanks! :D
Nice simple design, looks great for demonstrations. Seems to be more like an Oudin coil than a Tesla coil (which is fine - Oudin coils seem to be safer to play with).
Is there a difference between a mosfet and power transistor? They seem to function the same, or are they even just different names for the same thing? also, whether its power transistor or mosfet you say it doesn't matter what you use, and im just curious why.Thanks.
Be made my secondary coil. It has 470 turns. The diameter would be 0.0315 inches. The the gauge of the wire is a bit bigger than yours. And the height is 10 inches. How many turns would the primary coil have to be?
i don't have that transistor. Where can I get one? and it's not CHEAP either.💲💲💲
yes thank you please do that big test coil I've been I've been looking all over RUclips cannot find one that explains it's good enough as you keep up the videos and
probably, next video's title should be "how to make time machine"!! and pretty sure it'll go viral :D
+Arun Sajeev hahaha xD
If the number of turns in secondary winding are low can it give sparks
Thank you dude
Will it still work if I scale it up? I've built a small one and it works, but I was thinkg of building a bigger one: 5.5cm radius, 1000 turns, 0.5mm wire, 50 cm height for the secondary and about 5.5 turns, 1.5mm wire with 1mm spacing between the turns for the primary. This coil works with my sparkgap setup (makes 4-5 cm arcs) but will it work with this circuit too? Thanks!
Im thinking to make it i just some help i dont have a powersource will 2 9 volt work
If I increase the amount of turns on the secondary coil.
Would it so just be more power full or would transistor burn out?
Plz answer
Could I run 1200 turn 15 inch tall 2 inch wide secondary? If so would I have to change the resistor ohms
Awesome.., amazing👍
@5:32 - Feedback arc in the pot.... XD
The EASIEST way to do this without winding a coil is use a flyback transformer from and old TV set or CRT monitor.
Wicked cool. I’m going to try it
ive made it... it works... but... the mosfet gets hot really quick... any idea to make the relay circuit with dual mosfet?
Yo! you need a zener diode connected directly at the gate to clamp your gate voltage to below VGS_max. That will help with failure rate of the switch.
+Pete S thanks that's a super great idea! :D
Let's my boost converter can output 80v, will this Tesla Coil still run? Or just blowup the transistor
Can I replace the pot with same value resistor? I can't find 1k pot? Also can I use irfz44n mosfet? Pls reply
Hello sir, I am a kid and I love to work with electronics, please suggest some tips to make this Tesla Coil because I am facing some issues with the circuit, I will be happy if you answer me.
