A Tesla coil seamlessly tops our list of “mad scientist” gadgets we need for the lab, maybe just a Jacob scale. Even then, it’s unfair merit because you know other people just need a ladder from Jacob for that amazing sound. Produces. Despite the sound effects, it’s Tesla’s coil all the time, no doubt.
Unfortunately, winding your own Tesla coil is something of a hassle. Even in relatively small constructions, you regularly want to install some kind of winding template just to make the secondary coil, which can be a task in itself. So when [Daniel Eindhoven] sent his windless Tesla coil to the top line, it immediately caught our attention.
The genius of its design is that the coils are etched into the PCB, completely removing human effort from the equation. Composed of 6 thousand lines with a separation of 6 thousand, the PCB coil manages to pack 25 meters long and 160 rpm. Coil in an incredibly compact package. Unsurprisingly, such a small Tesla coil would arguably not exactly be a powerhouse and, in fact, [Daniel] controlled to make everything work with the 500 mA output of his popular USB 2. 0 port.
In such a low-power configuration, [Daniel] was also able to upgrade the classic burst pulse generator with a PIC18F14K50 microcontroller, further simplifying the design. An advantage of a microcontroller for the pulse generator is that it is very simple to adjust the frequency operation of the coil, which allows attractive tricks such as having the coil “sing” bringing its frequency to the audible range.
For those looking to build their own version, [Daniel] has made the PCB schematic and firmware downloadable on their website. He also mentions that, in collaboration with Elektor magazine, he will soon produce a kit. will stay on the lookout.
This isn’t the first time [Daniel] has demonstrated his mastery of maximum voltage. It inspired us all the way in 2010 with its 11,344-Joules capacitor battery, the best for that laptop-destroying rail gun you were looking to build.
And of course, spoil all kinds of communication gadgets in the area.
That’s so cool!
Would it be possible to especially reduce its length by using two four-layer panels?
I idea wow you will have to get a kit of this. . . . . . . £88. 95. . . . . Maybe not!
You can buy mini tesla (assembled) coils on eBay for around £15
My God is going to make a hole in the ozone layer
Does that create ozone?
You gain something, where you don’t want it, you lose something, where you want it.
When you heat the air to high enough temperatures, you get nitrogen oxides, and many of them deplete the ozone layer.
Interesting, I had no idea. Good to know!
If you ever looked at the back of an old TV or other rubber-insulated high-voltage device, you will see the rubber harden and perish. This is the result of the volatile decomposition of ozone and nitrogen and the formation of nitric acid. which hardens and eats away at rubber and some plastics.
However, it is ideal for selling healing and skin regeneration. It is also used in hospitals to kill bacteria.
It seems to be the right length to put old discs, I wonder if it will erase them. Save making a mess with a hammer:)
The microwave will do this in about five seconds.
Save this hammer: the strength of the magnetic box is proportional to the existing one, and the one here is very, very weak.

It confuses me for a moment every time Americans use “millet” to refer to “you. “Especially in a sentence that also uses meters!
He used to paint at a stall with his own device store. I had to paint semi-closely with machinists on projects while I was there. It has driven me crazy, does anyone know why you and a thousand are the same?I imagined you meant a thousandth of an inch and Mil meant a millionth (but what, I’m not sure)?
French culpo, of a thousand, 1000.
From which we also lower millimeters of which there are a thousand consistent with clear meter.
The French are to blame, it was the ancient Romans.
They may have only fought the legions.
French yes, “thousandth”
Everyone was complaining that we weren’t using the metric system.
I agree. One billionth = one thousand is confusing. Especially if it grinds into the diversity of 10,000e.
When I became a machinist in the 70s, we used the word “Thousandth” to mean a thousandth of an inch. We have machined portions of pottery for many, many giant corporations (Bell Labs, NASA, IBM, ATT, etc. ) and almost their engineers also used this term when we were in the design phase of a project. I would also see it used on many levels.
In fact, “Mil” means “One Thousand. ” It has and probably will. Its definition is like number 3 on the list.
Mil also means millimeter and NASA now uses the metric system, so if the contracting corporations use it as 1/000th of an inch, I guess it makes a mess.
It’s the boy’s
This type of tip winding is also found in ultra-compact transformers; They make “planar” ferrite cores designed with a small hole of about 1 to 2 mm for a published circuit board:

SDR flare transmitter?
This spiral. . .
Fantastic and use of PCB transformers!
No PCB file, pshhh!
By the way, if someone wonders where to locate flat coils, without having to pay for a very high-quality printed circuit board, open an old 3. 5″ floppy drive.

Underrated comment of the week!
(When the fish has no fins it has teeth and is scary. . . is a brunette)
When tennis is your bee and ranks third, is it A. Murray?
This would possibly be ideal for making a wonderful tweeter. It would be wonderful to be able to inject audio, but it turns out that it needs charging and pulses in the video, I guess, because of the low voltages used. Not ideal for audio.
Hi, I’m looking for a way to create spirals and then import them as a symbol in KiCad, any suggestions?
