Hello dear readers andthe inhabitants of our site!
Surely almost every one of you has heard about the famous Tesla coil many times, but your hands did not reach its assembly. Perhaps many believe that this is a very complex device.
In this article, the author of the KJDOT YouTube channel will tell you how to make this device in miniature.

This homemade product is very easy to manufacture, and even a schoolboy will cope with it.

Materials
- Copper wires 0.25 and 1.2 mm diameter
- Transistor 2N2222A
- Resistor 22Kohm
- Battery 9 V (krone)
- Battery connector
- solder
- Polyethylene tube, a piece of plywood
- Insulation tape
- Sandpaper.


Instruments, used by the author.
— 
— 
- Hacksaw, wire cutters, scissors.

Manufacturing process.
So, the author offers to get acquainted with the device diagram.

The author will use a polyethylene tube as the coil body, and a PVC pipe will also be suitable. Its outer diameter should be about 20 mm. On one edge of the tube, he fixed with insulating tape the edge of an enameled wire with a diameter of 0.25 mm, and began winding. This will be a secondary, high voltage winding.



In total, it will be necessary to make 200 turns, it is important to lay them tightly to each other, avoiding overlaps and passes. Breaks are also unacceptable. The last turns are also fixed with an insulating tape.


The author cuts the excess length of the tube with a hacksaw.

For the manufacture of the primary winding, a wire with a diameter of 1.2 mm is needed. Its edges are cleaned with sandpaper, or a knife. The number of turns of the winding is four.



So, the coil is glued to a small board with hot glue.


Then, the primary winding is put on the coil, and fixed in its lower part. Also, a transistor is glued to the base.


The transistor collector is soldered to one of the terminals of the primary winding.

One terminal of the high-voltage winding is soldered to the base of the transistor. The second will remain free.


The legs of the resistor are shortened, and it is soldered between the base of the transistor, and the second terminal of the primary winding.



Now it remains to solder the negative power wire to the collector, and the positive wire to the second terminal of the primary winding. All soldering spots should be carefully insulated. Hot glue will completely cope with this task.



You can connect the battery to the terminals and start the test. The fluorescent lamp lit up.The LED soldered to a small coil also glows.



And so it looks in the dark.



I thank the author for the simple and easy to repeat Tesla coil circuit!
Repeat and you are a simple device! Be careful, you are dealing with high voltages!
All good mood, good luck, and interesting ideas!

Respect to the author and journalist that I described this homemade product. There are legends about the Tesla coil. But no one noticed that the top wire is not connected to anything. Respect Nikola Tesla!

Tesla is a great combinator who fooled the heads of world capitalism.
What transistors in Tesla's time?
What you offer is a Rumkorf coil or an ordinary doorbell. The chopper controlled by the magnetic field of the core of the electromagnet creates an EMF in the coil. A high-voltage transformer converts this EMF into the etheric space. If we connect a capacitor to the primary coil, we get a clear frequency with harmonics - these are the first spark transmitters in the world to work on this basis.

I fundamentally disagree with the question. In technical terms, this is not a miracle, and a student is smarter than Archimedes and Aristotle, by the end of his life if something opens maybe. Well, I’ll give an example to understand the process.
Everyone knows from the school curriculum that in a living organism (such as a person) it consists of a billion cells that are constantly replaced by the body itself. all cells are the same. And about 40 years the question arose of how this technically happens. They put forward the hypothesis that there is a binary helix genome, photographed, and received a negative of a living cell. We assumed that this spiral creates coherent radiation in the rays of which a hologram is formed, and a living cell is constructed from it that is identical to the very first cell. What kind of rays and who could come up with science is not known.
And to answer this question you need a philosophy, and simple knowledge, who could come up with this crap, with respect Vasily. .

Thanks. But I did not give her an example for the sake of boasting. Among her “colleagues” there are many more of the same ones ... who are interested in “How ?!”, and not just “there it is!”)))). But there are those (and most of them) who do not need it ... So ... Just to pass the tests ...

The simple user will not care how and what works. In general, it is necessary to judge the inventor of fire for a long time for the existing fires ... And those who use useful tools to the detriment of others due to personal gain, somehow remain in the shade, as it were, they do not exist.
But this is not on the topic of a specific homemade product. Controversies are best discussed in a separate topic!

So it’s important how exactly they advertise ... Nicola hardly left a will so that he would be advertised somehow. As far as I know, he was a modest man, despite the fame and merits at the time.
If someone advertises to someone, then there are reasons for that. And already everyone draws conclusions for himself.
Your daughter is smart. Apparently the best was transmitted from his father. ;)

Thanks to Tesla and the inventor of the oscillatory circuit, everything on the earth shakes and heats. with increasing frequency, living organisms are getting worse and worse !!! and what about non-ionizing radiation, if the gas in the lamp glows. and fools do not care.

400 volts with another transistor and no need to look in the dark. and if the coil is made flat and multi-starting, the spark is many times larger.

Nikola Tesla was a comprehensively developed personality, in different areas his contribution is.

Leonardo da Vinci, too, "noted" in all branches of science ... But, since you think that "everyone was smarter before," then Tesla is worthless compared to him!)))). Leonardo is much more ancient ...))))

(sorry, no offense)

Yes, what insults there !! I'm far from a student.)))
... And here, your example is not correct! The device for reading knowledge (It is knowledge, not memorized information) is always with you for those who have this knowledge !!! Because, it was through this "I / O device that this knowledge got them" hard ".)))
But, on the other hand, my daughter (not even a son)))), having graduated from a technical university, perfectly UNDERSTANDS (and does not know) what she studied. (And not only!) And now she is engaged in scientific work (on a voluntary basis, mind you !!! Not for money! But because she is INTERESTING !!!) ... And, by the way, when I am her (then still a schoolgirl) middle classes) somehow bought a "plasma ball", the first thing she asked me to explain HOW such an effect is achieved !!! And when I gave her a home-made fake fireplace where neon lamps were used (he is in my profile), she immediately became interested in this effect. And I began to look for information about the glow of some gases in an electric field).
So, you do not need to row all current students under one comb! ...I don’t know your age, but I, for example, are about fifty, and I remember very well that during my student days, the older generation did the same with might and main: They de understood everything, but we already only crammed and don’t understand anything !!! And, interestingly, for a long time I myself had the same opinion about those who are now forty years old ... This, unlike us, is already "a generation without a tendency to build up" ... So I thought, and I found it very a lot of confirmations ... And only with time I realized ... That I "want" to find these confirmations !!! And this generation is no different from mine and from the generation of my parents ... Each has both analytics and geniuses ... Even in modern young ones ... (Something to me with these words the surname "Bazarov" pops up in my memory. .. Why?))))
I do not underestimate Tesla’s abilities ... I just hate to push everyone and everything! After all, take the average layman, and he will not know what exactly we are grateful to Nicola for, but he knows for sure that he, the rascal, discovered some energy that would destroy the whole world if he did not burn the diaries! ...
And only for this EVERYONE knows him !!!
And I, for example, do not think that his discoveries “weigh more” than, for example, the discovery of the “superconductivity effect”, or, in general, the discovery of electricity itself !!!

I agree with you. The ancestors were harder than us, but they were able to make their discoveries.
Bold even risking their lives checked the resistance of their wing to flight.
And about the primacy of Radio, a dark matter. Here, apparently, the time has come and different people embodied similar ideas, each in their own way. By the way, Tesla conducted experiments with radio not only transmitting dots and dashes, but at the time he had already created radio-controlled transport models (with telemetry transmission). And this is in those years ... And today, not everyone can even repeat this.
The Titanic has a sad story in general regarding Marconi, but this is a matter for historians.
About the Tesla transformer, apparently, the presentation at the school textbook level among the majority, without studying it more deeply, without reading the works of the author himself, discussing the intricacies of the processes in it, well, it’s kind of frivolous :)

Quote: Dmitrij
Most of the “geniuses” are just f *** some developments, studies, add something of their own, effectively demonstrate, and now they are the authors of this. In fact, this is all a rewrite ... And Tesla and Einstein, including not an exception ... Tesla just wound more wire and showed sparks

Fairly categorical judgments, Imho. And this is about the time of the beginning of 1900. After all, there was no information (specific)! Who did what and what. Sales of standards were not particularly. Therefore, skilled craftsmen made wings, like birds, and threw themselves from bell towers, rocks and so on. Final predictable fool
N. Tesla (among other things) did a grand project to transfer energy (and information) over a long distance (without wires!). The tower. There was nothing similar and close ... And then Marconi and Co. makes medium-wave radio transmitters ... and simple radio receivers (over long distances). And then the Titanic happened, etc. The need for radio communications (and development) was ensured. And the tower with kV and kA (kilo Amperes) has sunk into oblivion ... And the financing did not continue ... By the way, we don’t apply such power, because I made a receiving coil and pump energy from the central Tower for free. dance2

In fact, all progress lies with researchers, they are pioneers.

Asynchronous motor as an example ...

In 1888, Galileo Ferraris published his research in an article for the Royal Academy of Sciences in Turin (in the same year, Tesla received a US patent [4]), which outlined the theoretical foundations of an asynchronous motor [5]. The merit of Ferraris is that, having made an erroneous conclusion about the small efficiency of an induction motor and the inappropriateness of using AC systems, he drew the attention of many engineers to the problem of improving asynchronous machines


And the electromagnetic induction, on which I work all the coils, transformers and magnets, was discovered by Faraday. Tesla just wound more wire and showed sparks

Thanks to Tesla, we now have a more efficient alternating current in electric networks, asynchronous electric motors, and its converter, the Transformer, is used in scientific institutions where high energy is required with a minimum of costs. Nikola Tesla was a comprehensively developed personality, in different areas his contribution is. A huge number of patents.
His merits are hard to miss.
And about modern knowledge, there is such a cartoon (from FreMan), where he gives an example of a man with a flash drive, who is proud that he has terabytes of useful information in it, and he’s in any place and time where most likely there will be no device reading flash drives and decrypting this information - that's it! His knowledge is practically nonexistent. And what can he do? Maybe something can :)
Similarly, modern students. Units can think at least something, having the potential to invent a new one.

You know, I, as an inveterate pragmatist, always laughed at the universal worship of the “wisdom of the ancients”, and, as a result, “the search for ancient knowledge!” ... Yes, there is no “ancient wisdom” !!! What the hell are ancient superwisdom and superknowledge, if a modern good student has more knowledge than Archimedes and Aristotle !! Which existed in their time in single copies. (Lucky for them, with their brains to appear in the right place and take advantage of the resources of the powerful!)))))))
The same category of people firmly believes in wise, healing, traditional medicine ... But, in essence, "Traditional medicine is when people with a life expectancy of 70 years want to be treated according to prescriptions of people with a life expectancy of 35 years!" )))) Moreover, while not taking into account the evolution of viruses and bacteria! ))))
But, on the other hand, they know for sure that "Before, people were all healthy, because the environment and everything was natural" ... So I advise you to die in childhood, like most brothers and sisters of their grandmothers !!! In order not to cancel the natural selection, which we have canceled ... And, if you survived - to eat exclusively Curare poison - there all-all components are natural! ))))
So with Tesla! ... We already fanned it, promoted ... And the "Tunguska meteorite" is not a meteorite, but Tesla indulged !!! And he found such a freebie energy that he burned all the development so that mankind, not strengthened by the mind, would not harm himself !! And what did he just not invent there !!!

You are right in something and in your own way.
But the World is so wide and deep and all its secrets have not yet been discovered and have not been known by us - it’s simply not possible to squeeze under our awareness. Therefore, there is always a place for the unknown.

The meaning of any homemade product is in its use for a particular master.

In short, this circuit design solution can be very useful in such areas:
- master high-voltage generator in experiments on radio communications and radio lacquering.
- master oscillator in experiments with an electric field (el.statika).
- master oscillator for single-wire transmission of electric energy.
- master oscillator for swinging a more powerful electric generator.
- high voltage generator in aeroionification devices (Chizhevsky).
- master oscillator in wave energy experiments.
and much more ...
