I found if you stick something like quartz or a piece of ceramic tile in the spark gap it not only quenches the gap but also acts like a capacitor
Interesting
The L\C circuit is just so snazzy. It just wants to resonate and live!
You just got a new sub! :) Would love to see more stuff and builds about tesla coils and high voltage stuff so keep up the great work and stay safe!!
Thank you! Have plenty of projects I want to work on, so stay tuned.
Honestly that's really awesome how little it took to get it functional. I appreciate you sharing ⚡⚡
When I see “It should work”, I know something will be wrong, haha
You know it 😉
try using a flyback transformer from old crt tv
I love this idea! People always try to make the most perfect build. How about we do the opposite!
I did something like this just recently, except I used a variac and an NST to power mine, and didn't even do resonant calculations. But I have now, and am going to finish the tuned version soon!
Cool stuff! It's actually pretty interesting how these things at least somewhat work as long as you get in the ballpark with the resonant frequency. There are still all kinds of inefficiencies and better tuning would improve it a lot, but the fact that it can at least marginally work is pretty cool.
My first trash coil taught me it wasn't trash. Something like 6 splices with 3 different sized wire throughout, and over time lots of overlaps. Looking back was part of one of the most impressive setups I've ever had at low voltage.
I'm a middle school science teacher who loves to build things like this out of trash like this. Is there any chance that you could make a video that shows a bit more in depth how to build this? I have a few 10,000 volt ignitor transformers as well as a ton of microwave transformers.
Pff i made a slayer exciter with wire from old tv, wound on roll from sanwitch paper and primary was just an aligator clip. Of course sparks weren't big, ~1cm with 12v input, but hey it worked and it light up LEDs from like 30-40 cm
Damn Nick! That was interesting
Haha, thanks man!
Could you post video how to wire mots in series and one parallel to need to make a ballast
7:30 try using MOT caps, in parallel with diodes probably, and connect the spark gap directly to the both caps thermals, see if that works.
I'm not sure if this will work for you wirh 120V USA ballasts.In Europe I can use a 40W 230V fluorescent lamp ballast(a traditional iron core one,not an electronic crap) in series with the MOT primary.1200V 68mA power supply is created this way.
Yeah, definitely need some kind of ballast to limit the MOT current. For this and other projects as well. They like to go into saturation and start cooking their primaries with too much current.
@@CoilLabs They will get hot after 30 minutes of no-load.The primary is usually 1mm diamater aluminum wire in the cap ones and abour 1.25mm diamater copper in the better ones.the better ones have about 1.5 times the size and weight of the iron core for the same power as well.In some crap MOTs even the secondary is aluminum.
Try a flyback transfomer I did it it’s amazin
Cool!
Nếu tôi chỉ sử dụng 1 máy biến áp thì nó có hoạt động không?
Try using a flyback transformer
Heyho,
Just wanna spread some love.
That is really well made video and i like to build tesla stuff as well so it also was damn interesting.
For such a small youtube acc the video and the way u've done things is really nice.
U got a like and a Sub more. Keep going. It'll be great!
Thank you! I remember appreciate that!
@@CoilLabs You definitely need a Instagram acc. dedicated to this channel. ;)
I have one, actually! Go to the "about" tab on my channel. The link to it is there.
I wonder if two circular magnets mounted to circle the wire spark-gap would work.
To try to help quench the spark gap by applying a Lorentz force to the plasma with the magnetic field? Is that what you're thinking?
It looks like you used the secondary as a ballast. I usually see the primary used as a ballast with the secondary shorted. Is there any difference or benefit between the two methods?
If you put the primary of the one you're using as a ballast in series with the primary of the active transformer and short the secondary, you should get essentially the same result as putting it on the secondary side and shorting the primary. Doing all the impedance reflecting math should result in essentially the same outcome. Though not going to lie, I haven't actually worked it out. Since I'm running two MOTs with their primaries in parallel, but secondaries in series, I did it with the secondary, because I can't use just one extra MOT to limit the current of the two primaries in parallel.
biocharger ng is the correct name for it ig
Hmm !
😊😊
i need someone with a brain how to a make tesla energy lights ng (the ones that run one unit on ac and the other unit on dc
Are the transformers wired in paralel or in series
Transformer secondaries are in series and using a capacitor-diode voltage doubler. There's a link in the description showing the type of circuit I'm using.
Solely please
Use a fly back transformer from a tube TV it'll work better
looks like the secondary is breaking down some
Bro's trash coil is better than mine
Do not try this yourself = try this yourself
the sad thing is that my tesla coil is just a crappy lol
i subbed
How to make it better? I mean, how can it be made better with minimal change?
There are tons of issues with this and obviously making it "good" wasn't the point. One of the biggest issues is parasitics from the poor layout of the circuit by connecting everything together with clip leads. Another big problem is the secondary coil has way too few turns for this topology of circuit (spark gap) to be effective. It should be much smaller diameter wire with way more turns. There are many others, but those are the big ones.
@@CoilLabs thank you
@@CoilLabs what should be the diameter of the secondary wire for a tesla coil of similar size?
The way you figure that out is to choose a desired resonant frequency, then design the geometry of the secondary coil (height, diameter, number of turns) to achieve a desired inductance and the geometry of the topload to achieve a desired capacitance, which will determine the coil's resonant frequency. You have to do all of this in parallel though, so you just have to assume some values and then adjust them incrementally until you get the desired properties. For a small spark gap coil, I'd say 400-600kHz is a good resonant frequency. And usually a good number of secondary turns is 800-1200, so that should give you enough info to get in the ballpark with what wire diameter you need.
you proved it can be done, but did not tell how
Nice watch
Haha thanks!
I'm a Mason and often find myself in the scrap yard buying old transformers and electrical nonsense to build, some day may be a usable devise or something that may blow my teeth out.
Lol just seen it sorry
Im having a hard time picking a cap for my tesla coil....im using a 12kv 30ma nst and i bidded and won a marconi capacitor a 45kv pulse capacitor but i found out its 500pf...will this be to low or a issues...and what does the pf, uf, nf do for me in picking out a cap for tesla coils.... i know its the capacity it builds up between the terminals but in lemans terms i dont know why thay matters for what im using it for or in any case what a high or low pf, uf ect. Means .... if you could email me toddrhart at gmail would be great.... im self taught... i also am not sure where to ground the nst too i have a metal rack but im stupid and skipped some research and not sure what i should look for in a device to hook a ground up to....should it be in the earth or would my metal deak leg work well... sorry that was a extra question....hioe yoh get this as i have the guy waiting now on buying this capacitor off ebay for 95$ which i will back out of if that 45kv pulse 500pf is not a good choice for my 15kv 30ma neon sign transformer
Ok first thing, don’t buy specific capacitors and transformers from eBay. Get a old microwave from a op shop and use those parts. Trust me you will save a crapload of money, check out some other tutorials from other youtubers. Good luck (also btw just use a fly back transformer for best performance and safety) - advice from me, a 14 year old kid that loves high voltage stuff and plasma :)
Building a Tesla coil is one thing where you can't skip the research. There are a lot of good Tesla coil guides online that you can find with some quick Google searching. I recommend reading and trying to understand them completely before you start building anything. The question you're asking here about selecting the right capacitor all comes down to the specific coil you're trying to build. Tesla coils are loosely coupled resonant transformers and you have to design the primary inductor-capacitor (LC) circuit to match the resonant frequency of the secondary LC circuit. The design of your specific secondary coil geometry and choice of primary circuit topology (spark gap, solid state, vacuum tube, etc) drives the geometry of the primary coil, which then drives the ballpark value of the primary capacitor you should select. Doing this correctly and safely is an engineering design process, even just as a hobby project. You need to do the research and actually understand what's going on and why the specs of the different components matter the way they do.
Cood djb
My trashlacoil is way trashier and works better😤
..
Its quite shocking
