The magical Tesla coil generates high temperature and high pressure plasma, can sing, ignite, wirelessly transmit electricity, light fluorescent lamps, and has a wonderful arc. There are many ways to play, very interesting small productions. 

Tesla coil is a transformer (resonance transformer) that operates on the principle of resonance. It was invented by Serbian-American scientist Nikola Tesla in 1891. It is mainly used to produce ultra-high voltage but low current and high frequency. AC power. 

A Tesla coil consists of two (sometimes three) coupled resonant circuits. Tesla coils are difficult to define, and Nikola Tesla experimented with a large number of various coil configurations. 

Tesla used these coils for innovative experiments, such as electrical lighting, fluorescence spectroscopy, X-rays, high-frequency alternating current phenomena, electrotherapy and wireless energy transmission, emitting and receiving radio electrical signals. 

This Tesla adds the function of music playback on the basis of the ordinary Tesla: the arc excited air = the air that turns into the air vibration generated by the plasma. 

New concept speaker! It can play mobile phone and computer music with clear sound quality. 

The voltage input is 12-24V DC, and the arc length is 24V when 5--10mm is the most ideal. 

Small in size, complete in functions and functions, it can work for a long time without interruption, and can also light up neon bulbs, energy-saving lamps, strobe tubes, wireless power transmission, and rotating arcs.

common problem 

1. The resistance welding is wrong. There are two resistance values of 10K and 2K, which should correspond to those marked on the board. . 

2. The positive and negative poles of electrolytic capacitors and LEDs are wrong, and the long feet are the positive poles. 

3. The 80NF70 and BD243 models should correspond to those on the board. 

4. The Tesla coil is installed upside down. Solder the end with solder on one side to the circuit board. 

5. The intersection of the red line must be on the outside, and do not touch the Tesla coil, preferably about 1 mm away. 

6. Check the phenomenon of welding short circuit and virtual welding. 

7. The power supply voltage is 12-24V, and the current is more than 2A. It can be connected to the DC socket or from the fan interface. 

8. The blue light is the power light. If it is not on, check the resistance welding and the welding of the lamp. If the red light is on or off, don't care, just have an arc.

Precautions 

1. This product is safe, the power is not high, and will not be injured by electric shock, but it is not recommended to touch the arc on the top of the coil, there will be a burning sensation. 

2. Do not touch the heat sink after a long time of power on, the temperature is very high, especially when using 24v high voltage, the heat is huge, there is a fan interface reserved, please add it if necessary 

Cooling fan dissipates heat. 

3. It is recommended that no body or other objects be close to the coil when the Tesla coil is working, that is, no other objects can be left within half a meter of the coil, because other objects 

The body as a good conductor will make the coil form a good loop and absorb the energy of the coil, making the demonstration effect of the Tesla coil worse or impossible to demonstrate at this time! Please note; 

4. Do not put mobile phones, mp3 and other electronic devices close to the coil, otherwise the high-frequency magnetic field generated by the coil will interfere, causing the mobile phone, mp3 and other equipment to malfunction or even damage!
