- How to make a spiral shaped primary coil for a Tesla coil, in this case my mini/small spark gap Tesla coil, along with tuning and demonstrations. Once again, I use the JavaTC calculator as a starting point and then show how to tune it.

Thanks for another great informative video. I know these take quite a bit of time to produce, so hats off to you sir.
Great video on tuning a tc! Thanks
Awesome!!!!!! you getting there.
resonance is the key!! well done
Seems pretty weak, maybe the primary capacitance is just to small
How I made a spiral primary coil for my small Tesla coil. Enjoy!
Is there an alternative of javatc for slayer exciters?
Good job
Try winding it on PVC then flattening & opening out the spiral. It's a lot neater and kink free that way.
+Brek Martin Oh cool. I'd looked for any good spiral winding tricks and hadn't found any. I'll keep that in mind for next time. Thanks.
+RimstarOrg You start out on the size of the smallest turn, like the PVC your secondary is wound on, and open it out from there. I never did find out what the advantage of a flat spiral is over a completely vertical one, except maybe when it comes to tuning it maybe it’s just neater to lead the tap out from underneath.
Brek Martin
That's why I like the spiral instead of the vertical one, I find it easier to connect to the spiral to tune.
Nice plans, coil, and output, especially for that power supply. How hot do the transistors get?
ClevelandStorms Thanks. Surprisingly the transistors don't get noticeably hot, even after a few minutes of running. You do have to keep an eye out for the capacitors heating up though. It's not so bad with 4 1nF's in parallel for a total of 4nF, but I played around with just 1nF at one point and that heated up much faster. I'm thinking of making some Leyden jar type capacitors instead.
como fazer de um jeito que n fique com esse curto ?
Great video !!! Really helpful tutorial, a quick question though. I was wondering what if you made another secondary coil the same size as the one you are using in the video, but wound it with very thin wire like 32 or 38 gauge wire, would the decreased resonant frequency and increased windings ratio give you much longer sparks off of the top load?
Thanks! I really don't know the answer though. Keep in mind that you'd have to adjust the primary side to also have the same resonant frequency.
+RimstarOrg Thanks !!!
Hi....
May i ask a question
Where to connect the base of the secondary coil ?
Thank you
In a spark gap Tesla coil like this one it's usually connected to Earth ground.
👍🏼👍🏼👍🏼👍🏼👍🏼 5 thumbs up! lol
Dose it matter if the primary is wound clockwise or counterclockwise?
Green Silver Thanks! I've never read anything about it, but I erred on the side of caution and wind my primary in whatever direction I wind my secondary. If anyone knows if it matters, please let us know.
wow coll
The florescent tubes lighting, how does that happen? The area near the coil must be energized? Kind of hair raising to see!
Yes, there's a strong, fluctuating electric field surrounding the tall coil and the top load (ball on top). Somehow that's interacting with the gas in the fluorescent tubes, causing the gas to fluoresce (give off light).
How many volts do the electric sparks have?
Brandon Fisher It's hard to say. A rough guess can be made based on the spark length, which is around 2.5cm/1 inch. Unfortunately the estimates take into account the shape of the electrodes and they don't usually involve a sphere and a needle like this. So I'd say somewhere around 30kV. Here's a sample table www.kronjaeger.com/hv/hv/msr/spk/index.html
what is the program you use for calculating and is it available for android?
It's this one www.classictesla.com/java/javatc/javatc.html and I don't think it's available on android but try looking about their website to see. I guess you could run it in the Chrome browser on android.
Sorry for the delayed response. TH-cam seems to not always be notifying me of comments.
if we keep our hand around telsa than we get shock or not
This small tesla coil will give you only a sharp shock, but not very painful. If it's a bigger tesla coil then it may not be safe.
May I suggest an increase in power by... lets say 20 times... :D
Awesome work!!
Binj Komisar Thanks! Re increasing the power, it's already loud enough for the neighbors... I don't want them coming at me with pitchforks! :)
RimstarOrg
Hmmm... The old neighbor scenario.... Hmm... Are you in a Solid State of mind.... ;)
Binj Komisar :) I still have a few more things to do with the ionic before I go solid. But the quieterness :) of solid will be nice.
RimstarOrg
Excellent... Cheers to steady progress in a forward direction my friend :)
Please tell how to use Java tc
I've put everything I know about how to use it in this video and in my video about making the Tesla coil th-cam.com/video/0SaEPW_iMF8/w-d-xo.html.
How many volts for input?
I didn't measure it but it's limited by the width of the spark gap, the shape of the spark gap electrodes, and the moisture in the air. With my spark gap, I'd guess it was only a few thousand volts. However, current is also important. You can charge up the spark gap to the same voltage with a low current power supply like one from a fly swatter or with a higher current one like I used. Both will provide the same spark. However, the fly swatter one will take a lot longer between sparks, even a few seconds and so it won't be as useful.
You can see more about how I make this Tesla coil starting with this video th-cam.com/video/vemF7p0cbHU/w-d-xo.html and this is how I made my power supply th-cam.com/video/-KFhBVfpfDw/w-d-xo.html
LOL! Yesterday i saw about how can i make tesla coil but i found only bad exampled videos or some sicribe what was ununderstandable for me XD
Hi
When I see a Tesla coil they always look like that or a small variation of the primary coil, but is it possible to build something like the C&C RA Tesla coil?
So like this: vignette2.wikia.nocookie.net/cnc/images/9/9c/Tesla_Coil.JPG/revision/latest?cb=20061001005643
The closest thing I've seen is this, but that is inverted:
bugman123.com/Tesla/Schematic.jpg
RadioKies I don't see why a Tesla coil couldn't be shaped to look something close to that.
this software name
The software is called javatc. You can find it here www.tesla.nu/programs/javatc/javatc.html. I talk about it more in the video where I show how to make this tesla coil th-cam.com/video/0SaEPW_iMF8/w-d-xo.html.
Shakey as hell, you need a joint my friend.
What's that machine
Which machine? The Tesla coil in this video is the one I show how to make in this other video th-cam.com/video/0SaEPW_iMF8/w-d-xo.html.
Very good but small tesla coils that works with flayback transformers never work as well as neon sign or microwave transformers
🇧🇩🇧🇩
I honestly don't like the spark gap coils just because they're a nuisance with the sound.
Yeah, I know what you mean. That's why I haven't pursued this further -- too noisy.
