coil info:
2 mots,
Asynchronous rotary spark gap ( wood router ) 12 electrodes on wooden disc.
Primary: 5 and a halve turns used. 10 turns total, 6mm tubing.
Secondary: 7cm x 38cm (adjustable height) about 1100 turns.
Toroid: 10cm x 38cm (adjustable height)

I haven't built one of these in about 20 years. Last one I built was based off a 150ma 8kv transformer, forced air static gap, a home made acrylic/flashing/mineral oil cap. It was loud but made some very nice violet arcs. Best arc distance I managed was just shy of about 4 feet.
damn this guy is impressive
I'm in love with that primary tap, so neat. ;)
Only 4kv? Nicely done. Those must give a nice bit of power to the coil. Probably about 500ma, yeah? From what I've read they can handle some abuse. That's about a 2kw coil. Planning on a similar power supply. But I'm thinking about submerging the transformers in mineral oil
Very nice! Im building my own one, but a lit smaller. If i finish it ill share a video here :)
Interesting design with the rotary spark gap
Very nice! Looks like your primary is wound counterclockwise from the inside out and the secondary is wound clockwise. Is that correct?
Very nice! Can you tell what kind of ballast you using? Or where to get that transformer? Tnx
Just an old large transformer, nothing special. You can also just use another MOT
That is amazing thank you for the inspiration I am building my own dual MOT Tesla coil and love it when I come across vids like this! Any advice on where I can buy my MMC bank?
just buy a bunch of small capacitors and wire them to meet the needed capacitance and voltage rating.
What kind of ballast do you use for the microwave transformers?
advance transformer ballast 500w
another transformer
shematic please ⚡️👌
beautiful coil.
I have an urgent question concerning my coil. The resonant cap size for the coil is .01uf while the resonant cap size for the dual mots is .6uf, how do I get around this. And how did you figure out what to do??
Platinum Science what exactly do you mean by that? Can you explain in more detail.
there is no such thing as resonant cap size for the power supply BUT there is something called recomnded maximum capcitance for the power supply which happens to be around 5 or 6 micro farads for dual mots like what you said so you dont have any problems with youre resonant cap size of the coil
Why an adjustable primary wire? why not the wires at the end and at the start on the primary?? I wanna make one too.
What wire gauge did you use on the secondary?
Probably 30-+1 awg
hi, i have some question, is the strike rail a circle connected to ground to prevent sparking to the secondary, and why does it need to be a open circle
Ok the strike rail is to prevent discharge into primary coil . As for the reason it has to be an open loop a closed loop would would be like a em antenna causing interference to be emitted everywhere
good video..although schematic is missing/
what is the diameter of the secondary copper wire?
That's a brilliant coil, mate! I'm just judging from the video but the discharge is pretty thick which implies a fairly powerful discharge. I noticed you had a bank of capacitors in the primary circuit. Were you ever in a position to replace this bank with (say) an equivalent single capacitance which might have a lower ESR?
Whatever you've done it's worked well! Thanks awfully for taking the time to share this video clip.
Could I get the schematics please.Thankyou.
Can it disable coronna virus????
probably, and anything else that walks in front of the arcs.
hey Job, geweldig goed gedaan, prachtig apparaat !!
what gauge wire is used for the secondary coil and why doesn't it get burnt up when it is putting out those awesome freaking streamers?
notny411 because it's only such low current
Power=current * (resistance)^2
Hi server the secondary should be insulated properly to avoid internal acring
what is the total ballast resistor value? please
impressive , could you tell me what purpose the chokes serve,
isn't the ballast for the same reason ?
os transformadores precisão ser iguais ou tendo 2 kv já é suficiente? ?
did you make any calculation before building this masterpiece ?
Perfect!
Tks
Hi, how did you calculate the primary cap? I have some MOTs but I don't have the nominal power and can't calculate the capacitor to begin with my tesla coil design. Can you help me with the design process? i don't know whixh parameters must be calculated and ones must be selected by me. Thanks a lot.
Gabriel Droguett Olea usually mots have an output of 2100 volts, go to deep fried neon they have calculators that will tell you the capacitance needed for your power supply
Knowing the characteristics of MOT"S wouldn't you fly through them? With all that arcing it seems like it would murder them. Just wondering. Nice job though. :)
Well, mot's aren’t build to power a tesla coil of course, but they can handle a little abuse and they have the protection of a large ballast and a safety gap (and terry filter) so they should be fine … I hope. :) haha
+Job Beeftink how exactly would it be best to go about hooking two or more MOTs up together to power a t coil? You should make a more detailed description for me if you can. Can I mod the transformer for better performance and if so what exactly would I do?
Job Beeftink Can put a schematic together? It would really help.
Mr. MHz I already built a basic spark gap tesla coil. I know how they work. I know how to be safe. But I built it in one night (I was rushing), and it's not very impressive because I paid little attention when building the primary, secondary, and top load. You can barely see the sparks during the day.
I'm interested in building one of these. I have one question for you. What is the advantage of the rotary spark gap compared to a regular spark gap?
interval of firing is more reliable/stable, easier to work with.
electrodes are cooled constantly, speed control while gap is firing, really handy.
ionized air is moved away relative to the gap so that way a continuous arc wont jump the gap
Hey Job, really nice. I ask if you can enfatize on the making?
I got shocked by a MOT before. I probably almost died.
Did you touch the terminals with both hands or just one?
@@josephrossman1600 hard to remember. I remember the most horrendous electrocution I've ever had. It feel, and it came undone. I felt it go through my chest.
It burned holes wherever it touched.
, see, I'm usually MUCH more careful. Just that one time. Didn't even get the fluorescent to light from an okay distance away. :/ (was also using the magnetron)
So very safe of me... I've done it before and it went great. I just got in a big hurry.
Dear job! Can you send me a detailed video or photos from this tesla coil?
Thanks!
Send photos or videos to my email : hevizibalazs2000@gmail.com
Job Beeftink i really need your help. What is the voltage and current output of your MOT's? Im trying to use MOT's but im getting a output of 6000V @ 137mA! This current is too high and the optimum MMC would be 118nf!!! How did your MMC value get down to 56nf? Please help.
Kokodps normal output of a mot is around 1000-2000v 800ma load
Veeeery Cool!! I would say Awesome!
Prefect
Awesome !! Using a voltage doubler after the MOTs ?
no voltage doubler.

how did you make the templates for the primary coil?

Open this in emachineshop and you can see how the holes are lined up and measurements etc. Also you can redesign everything if you wish. Then print it scale1:1
***** Thank you soo much.

The power supply just provides 4kv AC !
Did you make your capacitators? If not, where can I get some like them?
Thanks.
I don't know where to get them. I only bought the mot's, copper wire / tubing and toroid, everything else is reused stuff. ebay maybe?
Job Beeftink
hi how are you?
can you pleas help me build Tesla coils machine if you can send me all the information to sam.murkis@outlook.com
as well what i need and the wiring pleas pleas thank you very much.
Mouser sells then
Total cost?
Robotic Nerd if you find most of the parts (mots etc) than it will cost arround 200 bucks
