Ah, the charm of candlelight! There is nothing better than the warm and soft glow of a real candle to explain "romance"-or "long power outage". However, if you don’t like burning wax for some reason, then this plasma electric candle may be the ideal choice for your next dinner for two.

This reimagining of the inconspicuous candles was achieved by the plasma super fan [Jay Bowles], who has extensive experience in plasma and the high-voltage circuits that often accompany them. Even so, he still had to seek help with circuits, basically a 10-MHz Class E oscillator from [Leon] on the Teslaundmehr channel on YouTube. The most prominent feature of this structure is the large resonator coil surrounded by a shorter primary coil and located on top of the heat sink of the MOSFET driver. [Jay] The consistent acrylic style is well reflected here, and the resulting construction is very cute.

However, the tuning process sounds like sheer torture. It takes a lot of adjustments-and a lot of MOSFETs-to make the candle produce a stable flame. But once this is done, the results are amazing. The size, shape, and—occasionally—color of the plasma emerging from the breakthrough point on the resonator coil is almost the same as the candle flame. It is also hot enough to cause some damage, so please be careful if you build it. We have included [Jay] and [Leon] videos below; [Leon] has good step-by-step construction instructions.

We have been following [Jay]'s journey in the plasma universe, from his cheap and simple Tesla coil to the use of corona discharge to clean his hands. He even hosted a hacker chat on this topic last year.

Note: [Jay] contacted us after posting information about mitigating RF noise. He conducted experiments in a reinforced concrete building with grounded metal screens on the windows. An RF expert friend checked the entire spectrum and no external leakage was detected. It sounds like our business.

Very good build, but I certainly hope that he will not use it often.

...Or if he did, he would put it in a Faraday cage.

I want to know if it will destroy all wireless networks within a radius of 1 km.

Or light up the entire ionosphere

Does the Tesla coil manufacturer know that other people use the RF spectrum? Do they try to adhere to the ISM band like induction heating personnel?

:) It not only provides a beautiful plasma halo, but also makes sourpuss ham exude a terrifying flame, even better! To complete the effect, couple it to a source of randomness for unpredictability. And move it from time to time.

Magat did it with their Ion Tweeters. They used a 27.12MHz miniature Tesla coil. Or Boys from HCRS.AT, they made 1500W VTTC in 27MHz ISM.

The radiated power is very small. This is an extremely short antenna for 30m wavelength signals. I don't know how many, but if it blocks anything that is not on the working frequency for more than 10m, I will be surprised.

It may be electrically short-circuited, but its Q value is very high (it must be so in order to work). The radiated power can easily reach a few percent of the input power, which is billions of times higher than the power allowed by the actual product.

Unless he takes special shielding measures, the thing is easily strong enough to be found anywhere on the planet. It will be because it is in a ham CW band.

And 15m, 10m, 6m, 5m bands. You might be surprised how little power is needed to eliminate DX reception.

Smack in the 30 m band of amateur radio. I want to know how a fox feels when hunting? Or was he forgotten until the hunter extinguished his light?

Hello everyone, I am a creator. Just note that my studio has concrete walls, floors and ceilings. I chose this special place to live because of the natural lighting and the protection of the concrete walls. In all experiments, my windows were covered with grounded metal mesh. I did take care not to pollute the local radio bandwidth, and even contacted the FCC in my last episode of radio transmission. Hope you like this video. cheers!

excellent! This is absolutely cool and I am glad you have solid walls.

I would love to hear the FCC’s official statement on the operation of the Tesla coil.

The "protected" concrete will play a very good role in RF leakage: concrete is basically transparent at 10 MHz.

The screen on the window will also be approximately zero to prevent radio frequency leakage. You need to completely shield the room: no gaps, no holes, no gaps, or openings larger than a fraction of the wavelength.

You are operating an "unintentional radiator". Therefore, you do not need an FCC device authorization as an RF transmitting device. However, you are still regulated by 47 CFR Part 15 or if it is a product, you will be regulated.

According to the legal provisions, you still "should adopt good engineering practices to meet the specified technical standards to the greatest extent." And "under the condition of not causing harmful interference."

In fact, the FCC will not hunt you down like a dog. Well, until someone calls them and complains. But they do make expensive examples of offenders from time to time, which is always interesting to read.

Consider moving to at least the designated ISM frequency of 13.567 MHz or 6.78 MHz. At least your neighbors anywhere on earth will not feel inconvenienced.

I guess you haven’t figured out why they no longer invite you to parties?

A 1 candela gas plant...it is very expensive...lol (sorry!)

I heard that right, 16-32 volts and 4.5 amps? This is a very small flame, about 90W. With a radiator, does it get or just extract so much EMI?

A tea candle emits approximately 45 watts of heat, regardless of whether it is given or received.

Maybe you should use lead shielding, it sounds like you get something seriously radioactive.

My candle only gets hot when it is lit.

The flame may not be far from emitting 90 watts of heat. To me, only 90 watts of input power sounds very efficient.

Side note: My wife noticed that soy candles are not as burning as wax candles.

If you really want a good reading light, you have to kill a whale and process whale oil yourself. Wax is for fools.

"Don't be this walnut"? ? It looks like he is about 8 millimeters away from that walnut!

This reminds me of a children's TV series called "Super Car". The professor always tries to use megawatts of power and some technical magic to make toast (yes, with bread). Only ancient people would appreciate it.

Will this fill the room with ozone? Did not consider the beneficial effects on the ozone layer (it will certainly not reach), but if you inhale its negative health effects during a romantic dinner...

Prolonged inhalation of ozone can damage your lungs. I have 3 Tesla coils and I always open a window during operation.

In the youtube video, it is said that the MOSFET is in zero-switching mode. IMHO, this is not true, Mosfets cannot switch at those high frequencies. Mosfets works in the linear region, which is a type of Colpitts Oszillator. I had something similar in the 90s. 1MHZ coil, but with 2N3055 transistor.

What kind of gas is burning in the flame?

This is an electrical "flame". What kind of gas do you think is burning?

Must it be nitrogen, oxygen, and some argon?
