TESLA ON A PLANAR COIL WITH USB POWER. Tesla coil circuit for 220v

how to assemble a transformer with your own hands, the principle of operation

The work of kinescope TVs, fluorescent and energy-saving light bulbs, remote charging of batteries is provided by a special device - a Tesla transformer (coil). To create spectacular light charges purple resembling lightning, a Tesla coil is also used. The 220 V circuit allows you to understand the device of this device and, if necessary, make it yourself.

Working mechanism

The Tesla coil is an electrical device capable of increasing the voltage and current frequency several times. During its operation, a magnetic field is formed, which can affect electrical engineering and the human condition. Discharges falling into the air contribute to the release of ozone. The design of the transformer consists of the following elements:

• primary coil. It has an average of 5-7 turns of wire with a cross-sectional diameter of at least 6 mm².
• secondary coil. Consists of 70-100 turns of dielectric with a diameter of not more than 0.3 mm.
• Capacitor.
• Discharger.
• Spark light emitter.

The transformer, created and patented by Nikola Tesla in 1896, does not have ferroalloys, which are used for cores in other similar devices. The power of the coil is limited by the electrical strength of the air and does not depend on the power of the voltage source.

When voltage is applied to the primary circuit, high-frequency oscillations are generated on it. Thanks to them, resonant oscillations occur on the secondary coil, the result of which is electricity characterized by high voltage and high frequency. The passage of this current through the air leads to the appearance of a streamer - a purple discharge resembling lightning.

The oscillations of the circuits that occur during the operation of the Tesla coil can be generated different ways. Most often this happens with the help of a spark gap, a lamp or a transistor. The most powerful are devices that use double resonance generators.

Raw Materials

It will not be difficult for a person with basic knowledge in the field of physics and electrics to assemble a Tesla transformer with their own hands. It is only necessary to prepare a set of basic details:

• Power supply with a voltage of about 9-12 volts. The role of such a source in a home-made device can be performed by a car battery, a laptop battery, or a step-down transformer with a diode bridge to generate direct current.
• primary contour. It consists of two resistors with a nominal resistance of 50 and 75 kOhm, a transistor VT1 D13007 or a similar device with an n-p-n structure.

A mandatory element of the primary coil is a cooling radiator, the size of which directly affects the cooling efficiency of the equipment. A copper tube or a wire with a diameter of 5–10 mm can be used as a winding.

The secondary coil requires mandatory insulation in the form of paint, varnish or other dielectric treatment. An additional detail of this circuit is a serially connected terminal. Its use is advisable only with powerful discharges; with small streamers, it is enough to bring the end of the winding up by 0.5-5 cm.

Wiring diagram

The Tesla transformer is assembled and connected in accordance with the electrical diagram. Installation of a low-power device should be carried out in several stages:

1. Install the power supply with strict adherence to the correspondence of the contacts.
2. Attach the heatsink to the transistor.
3. Build an electrical circuit using plywood, a wooden box, or a piece of plastic as a dielectric substrate.
4. Isolate the coil from the circuit with a dielectric plate with holes for connecting wires.
5. Install the primary winding, eliminating its fall and contact with another winding. In the center, provide a hole for the secondary coil, ensuring a distance between them of at least 1 cm.
6. Fix the secondary winding, make the necessary connections, guided by the diagram.

The assembly of a more powerful transformer occurs in a similar way. To achieve great power, you will need:

• Increase the size of the coils and the cross section of the windings by 1.1–2.5 times.
• Install an AC source with a voltage of 3-5 kW.
• Add a terminal in the form of a toroid.
• Ensure good grounding.

The maximum power that a properly assembled Tesla transformer can achieve is up to 4.5 kW. Such an indicator can be achieved by equalizing the frequencies of both circuits.

A self-assembled Tesla coil must be checked. During the test connection, you should:

1. Set the variable resistor to the middle position.
2. Track the presence of a discharge. In its absence, you need to bring to the coil fluorescent lamp or an incandescent lamp. Its glow will indicate the presence of an electromagnetic field and the efficiency of the transformer. Also, the serviceability of the device can be determined by self-igniting radio tubes and flashes at the end of the emitter.

The first start-up of the device must be carried out while monitoring the temperature. In case of strong heating, additional cooling is required.

Transformer Application

The coil can create different types charges. Most often, during its operation, a charge in the form of an arc arises.

The glow of air ions in electric field with increased voltage is called a corona discharge. It is a bluish radiation that is formed around coil parts that have a significant surface curvature.

A spark discharge or spark passes from the transformer terminal to the ground surface or to a grounded object in the form of a beam of rapidly changing shape and fading bright stripes.

The streamer looks like a thin, weakly glowing light channel, which has many branches and consists of free electrons and ionized gas particles that do not go into the ground, but flow through the air.

The creation of various kinds of electric discharges with the help of a Tesla coil occurs with a large increase in current and energy, causing crackling. The expansion of the channels of some discharges provokes an increase in pressure and the formation of a shock wave. The combination of shock waves in sound resembles the crackle of sparks when a flame burns.

The effect of a transformer of this kind was previously used in medicine to treat diseases. High-frequency current, flowing through human skin, gave a healing and tonic effect. It turned out to be useful only under the condition of low power. With an increase in power to large values, the opposite result was obtained, negatively affecting the body.

With the help of such an electrical device, gas-discharge lamps are ignited and a leak is detected in a vacuum space. It is also successfully used in the military sphere to quickly destroy electrical equipment on ships, tanks or in buildings. A powerful pulse generated by the coil in a very short period disables microcircuits, transistors and other devices located within a radius of tens of meters. The process of destruction of equipment is silent.

The most spectacular area of ​​application is demonstration light shows. All effects are created due to the formation of powerful air charges, the length of which is measured by several meters. This property allows the transformer to be widely used in filming and creating computer games.

When developing this device, Nikola Tesla planned to use it to transmit energy on a global scale. The scientist's idea was based on the use of two strong transformers located at different ends of the Earth and functioning with equal resonant frequency.

If such a transmission system were successfully used, the need for power plants, copper cables and electricity suppliers would completely disappear. Every inhabitant of the planet could use electricity anywhere absolutely free of charge. However, due to economic unprofitability, the idea of ​​the famous physicist has not yet been (and is unlikely to ever be) implemented.

KACHER POWERED FROM 220V

But I didn’t have the necessary field effect transistor, or rather, I didn’t have field effect transistors at all, and therefore I decided to put a bipolar one, but quite powerful transistor D13009K. Kacher cannot work directly from the network, since the transistor, whatever it is, will still burn out, for this they put a diode to rectify one half-cycle and a power inductor with a resistance of several tens of ohms.

For bipolar transistors, the junction resistance is greater than for field ones, so I decided to limit the current even more. I put a 1kΩ resistor on the power supply and in parallel with it a 1uF capacitor. Thanks to the capacitor, the quality began to work with impulses and the transistor completely stopped heating up. Even without a heatsink, it was absolutely cold, but just in case, I screwed it to a small plate. Further, during the assembly process, I put another 5 microfarad capacitor in parallel with the power supply.

Zener diodes VD1 and VD2 protect the gate (base) of the transistor from voltage surges, they can also be replaced with one suppressor. The 1k resistor was replaced with a small transformer, it just had a primary winding of 1 kOhm, since the resistor was decently heated.

I collected all the elements of the kacher with a canopy, tested it and decided to place it in the case. As a body, I chose a cup made of thick plastic from instant mashed potatoes.

I cut out the bottom for a glass from thick cardboard and installed everything on it - a transformer and other radio elements.

In the course of assembly, I added a thermistor, in which, when heated, the resistance increases many times over. And glued it to the radiator. Suddenly, after a couple of hours of operation, the transistor will boil, and the thermistor will work and stop passing current - the circuit will turn off ...

The discharge turned out to be about 3 centimeters and is very similar to real lightning or a spark with SGTC. In general, the scheme is quite simple, and I think it will not cause any particular difficulties even for beginners. The main reason for the inoperability may be the incorrect phrasing of the windings, it is enough just to swap the conclusions of the primary winding. It is also necessary to check whether the secondary winding is “grounded” exactly to the base (gate) of the transistor - this is very important, because. the secondary winding simultaneously performs the role of OS (feedback). And of course the video of the work of the kacher:

Successful assembly and great streamers, [)eNiS was with you.

TESLA ON PLANAR COIL WITH USB POWER

This Tesla alternator has a coil in the form of etched windings on a printed circuit board. And it is connected via a USB line that powers the device. The resonance frequency is about 4 MHz. The coil has a transmission ratio of 1:160. The total length of the secondary line is 25 meters. The big advantage of the circuit will be that it is powered by USB 5V 1A. The output voltage level is approximately 30 kV.

This Tesla has all windings etched into the PCB (planar). The advantages of this method are the ease of production and the uniformity of the induction due to the constant distance between the windings. The spiral coil has a track thickness of 0.2mm, with a gap of 0.2mm as well. The total length is about 25 meters, 160 turns. The primary winding is on the bottom layer, under the outer ring of the secondary.

At the end of the secondary winding is a socket spring pin. Here you can attach a pin or needle. The pointed element causes a much higher local strength of the electric field, which makes it easier to start the spark.

Tesla generator circuit

Click on diagram to enlarge

Both the primary and secondary circuits use the series resonance of the LC circuit to increase the voltage. The circuit consists of several film capacitors and one winding on the bottom printed circuit board. The secondary consists of 160 turns of the upper layer and the environment tank. For optimal power transfer, resonant frequencies should be 4 MHz.

The duty cycle is directly proportional to the energy consumption. With 1A 5V you get the most out of your power supply with no more than 1.5% duty cycle. If you turn the generator on 100% of the time, then the circuit will draw over 300 watts. Clearly, this cannot be obtained from a regular USB.

The base frequency for the duty cycle can be changed to generate low frequency pulses (<10 Гц) или быстрые небольшие импульсы, которые попадают в звуковой диапазон (>20 Hz). Thus, you can make the Tesla "sing".

For optimal performance, there should be as little delay as possible in the signal path. The 4 MHz H-bridge requires very fast components. Therefore, the FZTX51 power transistors were chosen. The MOSFET driver uses the UCC2753X, which has very low latency and can be used at very high frequencies. The maximum voltage that these drivers can handle is 35V. With a margin of safety, the operating voltage can be no more than 32V.

Video of work

Operation is controlled by the S1 button:

• Short press: switching frequencies (5, 10, 20Hz)
• Hold for 1 second: return to the initial state
• Hold for 3 seconds: Switch to "high power" mode (1A) (red light flashes), and back to low power mode if the button is pressed again within 3 seconds.
• Hold for 8 seconds: turn off the blue LEDs or turn them on again.

During testing, the circuit successfully worked for more than 2 hours at a power of 5 watts. Firmware and all files for assembly - in the archive.

Tesla on the spark gap

The Tesla transformer, also called the Tesla coil, is a device invented by Nikola Tesla and bearing his name. Is resonant transformer, producing a high voltage of high frequency, but in some cases also low - 50 hertz. In general, after the successful assembly of Kacher Brovin, I wanted something more, and decided to assemble a Tesla Transformer much more powerful - on the spark gap (SGTC). I read a couple of articles, got some theory and started assembling the necessary parts. The scheme is simple, I think many novice Tesla builders assemble it according to it.

SCHEME

So let's analyze all the elements of Tesla's design:

1. POWER - I used two MOTA with shunts (transformers from a microwave oven).
2. My LOOP CAPACITOR was assembled from capacitors of the K78-2 type, its general parameters are: 25 nF 12 kV (K75-25 can be used).
3. PRIMARY WINDING cone-shaped, 6 turns of copper wire with a cross section of 3-4 mm
4. The SECONDARY WINDING is wound on a pipe with a diameter of 6 cm and a height of 30 cm, with copper wire 0.3 mm, approximately 1500 turns. After winding, the secondary must be covered with several layers of varnish.
5. DISCHARGE - RSG motor 3000 rpm, 4 electrodes on the disk (preferably copper)
6. FILTERS from HF are wound on tubes with a diameter of 2.5 cm and a length of 14 cm, winding in sections of 20 turns in each.
7. The toroid is made of corrugations with a diameter of 7 cm.

ASSEMBLY

First you need to assemble a case for our Tesla. I made it from thick plywood. On the first floor, we install power - two MOTs, it will be necessary to make grounding from the core of the motors. Here we attach filters from high-frequency. Now we go to the second floor: we put the engine with the disk, we fix all the electrodes. There will also be an MMC (loop capacitor). Now we connect everything together according to the scheme. On top of the whole structure we put a secondary coil, we fix the TOP on it, we ground the lower output. Around we wind the primary in the form of a cone, 5 cm high, 6 turns. Solder the primary to the circuit. We will make one more turn above it and ground it (this will be the so-called strike ring). It prevents the discharge from entering the primary winding.

Well, that seems to be all. We are trying to start: we turn on the RSG and apply voltage to the MOTs. Don't forget to ground everything! At correct installation everything should work immediately.

Result: 30 cm streamer, also when brought to half a meter, gas discharge lamps glow.

The Tesla transformer is a device invented by Nikola Tesla and bearing his name. It is a resonant transformer producing high voltage at high frequency. The device was claimed by a US patent dated September 22, 1896, as "Apparatus for the production of electric currents of high frequency and potential."

The simplest Tesla transformer consists of two coils - primary and secondary, as well as a spark gap, a capacitor, a toroid (not always used) and a terminal (shown as an “output” in the diagram).

The primary coil usually contains several turns of large diameter wire or copper tube, and the secondary about 1000 turns of smaller diameter wire. The primary coil can be flat (horizontal), conical or cylindrical (vertical). Unlike conventional transformers, there is no ferromagnetic core here. Thus, the mutual inductance between the two coils is much less than that of transformers with a ferromagnetic core. The primary coil, together with the capacitor, forms an oscillatory circuit, which includes a non-linear element - a spark gap.

The arrester, in the simplest case, an ordinary gas one, consists of two massive electrodes with an adjustable gap. The electrodes must be resistant to the flow of high currents through an electric arc between them and have good cooling.

The secondary coil also forms an oscillatory circuit, where the role of a capacitor is mainly performed by the capacitance of the toroid and its own interturn capacitance of the coil itself. The secondary winding is often coated with a layer of epoxy or varnish to prevent electrical breakdown.

The terminal can be made in the form of a disk, a sharpened pin or a sphere and is designed to produce predictable spark discharges of great length.

Thus, the Tesla transformer consists of two connected oscillatory circuits, which determines its remarkable properties and is its main difference from conventional transformers. For full-fledged work transformer, these two oscillatory circuits must be tuned to the same resonant frequency. Usually, during the tuning process, the primary circuit is adjusted to the frequency of the secondary by changing the capacitance of the capacitor and the number of turns of the primary winding until the maximum voltage is obtained at the output of the transformer.

1. SCHEME OF THE TESLA TRANSFORMER

As you can see, this scheme has a minimum of elements, which does not make our task any easier. After all, in order for it to work, it is necessary not only to assemble it, but also to configure it! Let's start in order:

MOTS: there is such a transformer in the microwave. It is a conventional power transformer with the only difference that its core operates in a mode close to saturation. This means that despite its small size, it has a power of up to 1.5 kW. However, there is also negative sides in this mode of operation. This is a large no-load current, about 2-4 A, and strong heating even without load, I am silent about heating with a load. Normal output voltage at the ILO - 2000-2200 volts at a current strength of 500-850 mA.
For all MOTs, the “primary” is wound at the bottom, the “secondary” is wound at the top. This is done for good insulation of the windings. On the "secondary", and sometimes on the "primary", the filament winding of the magnetron is wound, about 3.6 volts. Moreover, two metal jumpers can be seen between the windings. These are magnetic shunts. Their main purpose is to close on itself a part of the magnetic flux created by the “primary” and thus limit the magnetic flux through the “secondary” and its output current at a certain level. This is done due to the fact that in the absence of shunts during a short circuit in the "secondary" (with an arc), the current through the "primary" increases many times and is limited only by its resistance, which is already very small. Thus, the shunts do not allow the trance to quickly overheat when the load is connected. Although the ILO is heated, they put a good fan in the stove to cool it and it does not die. If the shunts are removed, then the power given off by the trance increases, but overheating occurs much faster. Shunts in imported ILOs are usually well filled with epoxy and are not so easy to remove. But it is still desirable to do this, the drawdown under load will decrease. To reduce heat, I can advise you to put the ILO in oil.

Amateurs please refrain from doing this. Danger High voltage. Deadly for life.
Although the voltage is low compared to a lineman, a current strength a hundred times greater than the safe limit of 10mA will make your chances of staying alive practically equal to zero.

I can upset some people by reporting that the ILO, although the ideal power source for Tesla coils (small-sized, powerful, does not die from RF like NST), but its price ranges from 600 to 1500 rubles and more. In addition, even if you have that kind of money, you will have to pretty much run around the radio markets and shops in search of it. Personally, I never found an imported ILO, not new, not used. But I found an ILO from the Soviet Elektronika microwave oven. He has much large sizes than imported and works like a normal trance. It is called from TV-11-3-220-50. Its approximate parameters are: power about 1.5 kW, output voltage ~ 2200 volts, current strength 800 mA. Decent settings. Moreover, on it, in addition to the primary, secondary and filament, there is also a 12 V winding, just to power the cooler for the Tesla spark plug.

CAPS: High-voltage ceramic capacitors are meant (series K15U1, K15U2, TGK, KTK, K15-11, K15-14 - for high-frequency installations!) The most difficult thing is to find them. Introducing a photograph:

High-frequency filter: respectively two coils that act as filters against high-frequency voltage. Each has 140 turns of lacquered copper wire 0.5 mm in diameter.

Very well distinguishable in this picture:

Sparkler: A sparkler is needed to switch power and excite oscillations in the circuit. If there is no spark plug in the circuit, then there will be power, but there will be no oscillations. And the power supply starts siphoning through the primary - and this is a short circuit! Until the spark plug is closed, the caps are charged. As soon as it closes, vibrations begin. Therefore, they put ballast in the form of chokes - when the spark plug is closed, the choke prevents the current from flowing from the power supply, it charges itself, and then, when the arrester opens, it charges the caps with double anger. Yes, if there were 200 kHz in the outlet, the arrester would naturally not be needed.

Finally, the turn has come to the Tesla transformer itself: the primary winding consists of 7-9 turns of wire of a very large cross section, however, a plumbing copper tube is suitable. The secondary winding contains from 400 to 800 turns, here you need to adjust. The primary winding is energized. At the secondary, one output is reliably grounded, the second is connected to the TOR (lightning emitter). Thor can be made from a ventilation corrugation.

That's all. Remember safety. And I wish you luck

In 1891, Nikola Tesla developed a transformer (coil) with which he experimented with high voltage electrical discharges. The device developed by Tesla consisted of a power supply, a capacitor, primary and secondary coils installed so that voltage peaks alternate between them, and two electrodes separated from each other by a distance. The device was named after its inventor.
The principles Tesla discovered with this device are now being used in applications ranging from particle accelerators to televisions and toys.

Tesla transformer can be made by hand. This article is devoted to this issue.

First you need to decide on the size of the transformer. It is possible to build a large appliance if the budget allows. Be aware that this device generates discharges high voltage(create micro-lightning) that heat and expand the surrounding air (create micro-thunder). The generated electric fields can damage other electrical devices. Therefore, it is not worth building and running a Tesla transformer at home; it is safer to do this in remote locations, such as a garage or shed.

The size of the transformer will depend on the distance between the electrodes (on the size of the resulting spark), which in turn will depend on the power consumption.

Components and Assembly of the Tesla Transformer Circuit

1. We need a transformer or generator with a voltage of 5-15 kV and a current of 30-100 milliamps. The experiment will fail if these parameters are not met.
2. The current source must be connected to the capacitor. The capacitor capacitance parameter is important, i.e. the ability to hold an electric charge. The unit of capacitance is farad - F. It is defined as 1 ampere-second (or coulomb) per 1 volt. As a rule, capacitance is measured in small units - μF (one millionth of a farad) or pF (one trillionth of a farad). For a voltage of 5 kV, the capacitor must have a rating of 2200 pF.

It is even better to connect several capacitors in series. In this case, each capacitor will retain part of the charge, the total retained charge will increase by a multiple.

3. The capacitor(s) is connected to a spark plug - an air gap between the contacts of which an electrical breakdown occurs. In order for the contacts to withstand the heat generated by the spark during the discharge, their required diameter must be 6 mm. minimum. A sparkler is necessary to excite resonant oscillations in the circuit.
4. primary coil. It is made from a thick copper wire or tube with a diameter of 2.5-6 mm., Which is twisted into a spiral in one plane in the amount of 4-6 turns
5. The primary coil is connected to the arrester. The capacitor and primary coil must form a primary circuit that is in resonance with the secondary coil.
6. The primary coil must be well insulated from the secondary.
7. secondary coil. Made from fine enameled copper wire(up to 0.6 mm). The wire is wound on a polymer tube with an empty core. The height of the tube should be 5-6 of its diameters. 1000 turns should be carefully wound onto the tube. The secondary coil may be placed inside the primary coil.
8. The secondary coil at one end must be grounded separately from other devices. Grounding directly "to the ground" is best. The second wire of the secondary coil is connected to the torus (lightning emitter).
9. Thor can be made from an ordinary ventilation corrugation. It is located above the secondary coil.
10. The secondary coil and the torus form a secondary circuit.
11. We turn on the supply generator (transformer). Tesla transformer is working.

Excellent video explaining the principles of the Tesla transformer

Precautionary measures

Be careful: the voltage accumulated in the Tesla transformer is very high and leads to guaranteed death in case of breakdowns. The current strength is also very large, far exceeding the value that is safe for life.

There is no practical application of the Tesla transformer. This is an experimental setup that confirms our knowledge of the physics of electricity.

From an aesthetic point of view, the effects that the Tesla transformer generates are amazing and beautiful. They largely depend on how correctly it is assembled, whether the current is sufficient, whether the circuits resonate correctly. Effects can include a glow or discharges generated on the second coil, or full-fledged lightning piercing the air from the torus. The resulting glows are shifted to the ultraviolet range of the spectrum.

A high-frequency field is formed around the Tesla transformer. Therefore, for example, when an energy-saving light bulb is placed in this field, it starts to glow. This same field leads to the formation of large amounts of ozone.

At the beginning of the twentieth century, electrical engineering developed at a frantic pace. Industry and everyday life received so many electrical technical innovations that it was enough for them to further development another two hundred years ahead. And if we try to find out to whom we owe such a revolutionary breakthrough in the field of domestication of electrical energy, then physics textbooks will name a dozen names that certainly influenced the course of evolution. But none of the textbooks can really explain why the achievements of Nikola Tesla are still hushed up and who this mysterious man really was.

Who are you, Mr. Tesla?

Tesla is the new civilization. The scientist was unprofitable for the ruling elite, and is unprofitable even now. He was so ahead of his time that until now his inventions and experiments do not always find an explanation from the point of view of modern science. He made the night sky glow over all of New York, over the Atlantic Ocean and over Antarctica, he turned the night into a white day, at this time the hair and fingertips of passers-by glowed with an unusual plasma light, meter sparks were cut from under the hooves of horses.

Tesla was afraid, he could easily put an end to the monopoly on the sale of energy, and if he wanted to, he could move all the Rockefellers and Rothschilds together from the throne. But he stubbornly continued the experiments, until he died under mysterious circumstances, and his archives were stolen and their whereabouts are still unknown.

The principle of operation of the device

Modern scientists can judge the genius of Nikola Tesla only by a dozen inventions that did not fall under the Masonic Inquisition. If you think about the essence of his experiments, you can only imagine how much energy this person could easily control. All modern power plants taken together are not capable of delivering such an electrical potential, which was owned by a single scientist, having at his disposal the most primitive devices, one of which we will assemble today.

DIY Tesla transformer the simplest circuit and the stunning effect of its application will only give an idea of ​​what methods the scientist manipulated and, to be honest, will once again confuse modern science. From the point of view of electrical engineering in our primitive sense, a Tesla transformer is a primary and secondary winding, the simplest circuit that provides power to the primary at the resonant frequency of the secondary winding, but the output voltage increases hundreds of times. It's hard to believe, but everyone can see for themselves.

The apparatus for obtaining currents of high frequency and high potential was patented by Tesla in 1896. The device looks incredibly simple and consists of:

• primary coil made of wire with a cross section of at least 6 mm², about 5-7 turns;
• a secondary coil wound on a dielectric is a wire with a diameter of up to 0.3 mm, 700-1000 turns;
• arrester;
• condenser;
• spark emitter.

The main difference between the Tesla transformer and all other devices is that it does not use ferroalloys as a core, and the power of the device, regardless of the power of the power source, is limited only by the electrical strength of the air. The essence and principle of operation of the device is to create an oscillatory circuit, which can be implemented in several ways:

We will assemble a device for obtaining the energy of the ether by the most in a simple way- on semiconductor transistors. To do this, we will need to stock up on the simplest set of materials and tools:

Tesla transformer circuits

The device is assembled according to one of the attached schemes, the ratings may vary, since the efficiency of the device depends on them. First, about a thousand turns of enameled thin wire are wound on a plastic core, we get a secondary winding. The coils are varnished or covered with adhesive tape. The number of turns of the primary winding is selected empirically, but on average, it is 5-7 turns. Next, the device is connected according to the diagram.

To obtain spectacular discharges, it is enough to experiment with the shape of the terminal, the spark emitter, and the fact that the device is already working when turned on can be judged by glowing neon lamps located within a radius of half a meter from the device, by self-switching radio lamps and, of course, by plasma flashes and lightning at the end of the emitter.

A toy? Nothing like this. According to this principle, Tesla was going to build a global system wireless transmission energy, using the energy of the ether. To implement such a scheme, two powerful transformers are required, installed at different ends of the Earth, operating with the same resonant frequency.

In this case, there is no need for copper wires, power plants, bills for payment for the services of monopoly electricity suppliers, since anyone anywhere in the world could use electricity completely unhindered and free of charge. Naturally, such a system will never pay off, since you do not need to pay for electricity. And if so, then investors are in no hurry to get in line for the implementation of Nikola Tesla's patent No. 645,576.
