Music Tesla Coil DIY Kit Mini Electronics Kit ZVS
Product Description :
The magical Tesla coil produces high temperature and high pressure plasma. It can sing, ignite, wirelessly transmit electricity, illuminate fluorescent lamps, and has wonderful arcs. There are many fun and very interesting scientific experiments.Tesla Coil is a transformer (resonant transformer) that operates on the principle of resonance. It was invented in 1891 by the American-born Serbian scientist Nikola Tesla. It is mainly used to produce ultra-high voltage and low current. High frequency AC power.
The Tesla coil consists of two sets (sometimes three sets) of resonant circuits coupled together. Tesla coils are difficult to define, and Nikola Tesla has tried a large number of coil configurations. Tesla uses these coils for innovative experiments, such as electrical lighting.
Fluorescence spectroscopy, X-ray, high-frequency AC current phenomena, electrotherapy and radio energy transmission, transmitting and receiving radio signals.
This Tesla adds music playback function to the ordinary Tesla, but because the coil is small, the power is small, and the generated arc is very small (the arc excites the air, and the air generated by the plasma vibrates) The sound is also very small, the sound quality is not very good, so please be careful to buy. Voltage input 15-24V, 2A DC power supply, the arc length is about 2 mm at 15V, small size, full-featured, can also illuminate LEDs, energy-saving lamps, fluorescent tubes, as shown in the video experiment.

Board size: 9.4CMx3.3CM;
There are some small holes in the coil installation, so that the glue is glued and the adhesion is firmer.
Plasma horn speaker sound: The principle is that the arc stimulates the air to become a new concept speaker for the air vibration generated by the plasma.
Compared with the electric spark arc plasma speaker, it has good sound quality, stable and safe, and can play any music without grounding.
Easy to use features; no doubt can be a new member of the home audio player!
2, do not touch the heat sink after powering for a long time, the temperature is very high, especially when using 24v high voltage, the heat is huge, if necessary, please add cooling fan to dissipate heat.
3. It is recommended that when the Tesla coil is working, do not put the body or other objects close to the coil, that is, leave the space within half a meter of the coil and leave no other objects.
Because other objects act as good conductors, the coils form a good loop, absorbing the energy of the coils, making the Tesla coils less effective or impossible to demonstrate! Please note;
4, do not put mobile phones, mp3 and other electronic equipment close to the coil, otherwise the coil will generate high-frequency magnetic field interference, making mobile phones, mp3 and other equipment malfunction or even damage!
The Tesla coil is a special high voltage device. The manufacture and operation of Tesla coils can result in personal injury or property damage, with consequences not related to the designer or supplier of the equipment.
Precautions and safety warnings:
1. Please pay attention to power safety. Tesla coils will produce extremely high voltage and high frequency arcs. Do not touch the output arc of the Tesla coil. After touching the arc. In the worst case, you will face an electric shock that can be life-threatening!
2. The operation of the driver board is also very dangerous. There are large capacitors on the driver board! Therefore, it is forbidden to directly contact the driver board after power-on! When the drive board is powered off, it is recommended to turn off the power, wait for the output arc of the Tesla coil to disappear, then cut off the drive power and leave the drive board for at least 5 minutes. Do not discharge manually, otherwise it will damage the capacitor!
3. Users under the age of 18 must be used under the supervision of experienced adults!
4. When the Tesla coil works, it generates a strong magnetic field and a strong electric field. It generates induced currents on surrounding metal objects, including wires, cables and nearby electronics, and produces powerful electromagnetic radiation! Therefore, if there is an electronic medical device carrier around, it is forbidden to use Tesla coils! Do not use a pacemaker! If you have a pacemaker, stay away from the device!
5, Tesla coil output arc noise is very large, it is recommended that you prepare earplugs!
6. The high temperature and high pressure arc of the Tesla coil causes the gas in the air to form other compounds, including ozone and nitrogen oxides. You will smell this when the Tesla coil is working, so please keep the Tesla coil. The working environment is well ventilated to prevent the accumulation of irritating odors such as ozone and nitrogen oxides!
7. The high temperature arc of the Tesla coil can ignite the item, so it is forbidden to place flammable objects around the working environment of the Tesla coil and place the relevant fire extinguishing facilities. workplace!
8. When the Tesla coil is working, the power components, heat sinks, etc. will generate heat. It must be ensured that the cooling fan is in operation for a long time throughout the working process! Excessive operating temperatures will burn out the drive board!
9. Do not directly touch the secondary coil after the Tesla coil is energized. There will be a certain induced voltage in the secondary coil. Do not disconnect the ground wire directly for at least 30 minutes, waiting for the charge to be naturally released!
Brief description of the driver board debugging:
1. First turn on the drive power, prohibit reverse connection, reverse connection will be bad! When the drive is properly turned on, the LED1 indicator on the engine board will illuminate continuously, indicating that the drive is working properly!
2, access to the fiber control signal, the indicator LED2 will flash according to the frequency of the input signal, indicating the normal transmission of the running signal! Since there is no overcurrent protection in the design of the driver board, the pulse control signal must be limited. I provide a reference here: in fixed frequency mode, the pulse width is up to 100us, the frequency is up to 440hz, and the music mode has the highest pulse width of 50us. If you also purchase a matching controller, I will set the pulse width frequency based on the reference value!
3. Connect the primary coil to the driver board and print the main terminal. Note that the winding direction of the primary coil is the same as the direction of the secondary coil!
4. Calculate the natural frequency of the secondary coil. Since the power half bridge uses IGBTs, it is recommended to suppress the natural frequency of the secondary coil below 200 kHz. The actual frequency of the secondary coil can be obtained through actual testing, and the signal generator and oscilloscope need to be prepared. The specific test method is: connect the signal generator of the oscilloscope and the ground wire. The signal output end of the signal generator is connected to the ground wire of the secondary coil. The fixed distance of the oscilloscope signal input terminal is about 10 cm, and the adjustment is started from the top of the secondary coil. The output amplitude of the signal generator is approximately 10V. A square wave or a sine wave can be output. Adjustment frequency
