The Tesla coil can produce high temperature and high-pressure plasma, which can sing, ignition, wireless transmission, and light fluorescent lamp. It has a wonderful arc. It is a very interesting small production of scientific experiments. This is a DIY Tesla coil Kit parts, which needs to be soldered and assembled by yourself.
Parameters:
1. PCB size: 4.0mm*8.0mm
2. Power: 15W
3. Power input: DC 15-24V. The current is 2A. DC5.5 interface / pin
4. Audio input: 3.5 socket, can be connected to mobile phone, MP3, computer audio
Principle introduction:
Tesla coil is a transformer that operates on resonance principle. It was invented by Nicola Tesla, a Serbia American scientist in 1891. It is mainly used to produce ultra high voltage, but low current, high-frequency AC power. The Tesla coil is composed of two groups of resonant circuits (sometimes three groups) coupled. The Tesla coil is difficult to define, and Nicola Tesla has tried a large number of configurations of various coils. Tesla uses these coils to carry out innovative experiments, such as electrical lighting, fluorescence spectrum, X ray, high frequency alternating current phenomenon, electrotherapy, and radio energy transmission, transmitting and receiving radio signals.
Tesla function:
1. Electric arc function: the traverse of the rear end will produce an arc. The arc can also ignite.
2. Septum light function: after the Tesla coil is electric, the fluorescent lamp can be lighted apart.
3. Music playback function: a new concept loudspeaker for an electric arc to stimulate air to make air vibration produced by plasma. You can play mobile/computer music, but the sound is small.
Installation steps:
Tips:
1. Install small components at first;
2. Install complex components preferentially;
3. Pay attention to the installation direction of components.
4. Make sure the soldering iron does not touch the components for a long time. Otherwise it is easy to damage the components.
Note:
1. This product is safe, power is not high, will not be injured by electric shock, but it is not recommended to touch the top of the coil arc, there will be a sense of burning.
2. Do not touch the heat sink after a long time power supply, the temperature is very high, especially the use of 24v high voltage heat huge, if necessary, add their own cooling fan cooling, or working hours lead to too hot, please turn off for a period of time Electric use.
3. Tesla coil is recommended to work when the body or other objects close to the coil, the coil next to half a meter blank can not be other objects, as other objects as a good conductor will make the coil form a good loop, absorbing the coil energy, making Testers Pull the coil at this time the effect of demonstration or deterioration can not be demonstrated!
4. Do not put cell phones, mp3 and other electronic equipment close to the coil, or the coil will produce high-frequency magnetic field interference, making mobile phones, mp3, and other equipment failure or damage!
Note:
1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
2. Please allow slight deviation for the measurement data.
3. Please allow 1cm-2cm error due to the hand measurement .
It only took me about 30 minutes to put together. Make sure you pay attention to the polarity of the capacitors and LEDs when you install them. Also, there are 2 different types of MOSFETs in the kit and the PCB will be labeled with where each one goes.
The pictures in the BangGood listing are pretty misleading as there is no electricity shooting out of it once it’s built as shown in the picture. I tried it from 3 volts all the way to 24 volts and, while things do change at different voltages, there’s still no electrical light show like they make you believe.
I also wanted to get this to help me practice soldering and, since this only has a few pieces in it, it is a pretty good kit to start with.

Works as stated. The blue spark is very tiny but the luminescent bulb lights up spectacularly. You can present it like a nice trick to the kids. I have added a thermo-silicone paste between the transistors and their heat sinks. And finally I put a small fan from an old video-card - no worry to burn out the transistors even at 25 V.

Q:
Debug Tips: I have to red LEDs on and nothing happening. Voltage measurement points? Does direction of primary wire matter?

Hello all does anyone have a wiring diagram in English? my kit is Chinese and I can't read Chinese I'm an Australian and would really appreciate an English translation,thank you kindly regards Keith

Q:
Hello everybody, I bought this kit and I can't find out how to assemble the LEDs, I know the long legs should go to the positive and the shorter leg to the negative but I don't know which way around to assemble them onto the PCB please help.

Positive (longer lead) goes to hole with square solder pad on PCB. Same for capacitors, pin sockets, and other polarised devices like diodes.... square pad = Pin 1 = Positive.

you have to provide your own power source. I have used old laptop power supplies. if you use a 24volt laptop supply you should add a small fan to cool the FET's

english instruction : use google translate app and press camera button for instant translate. it says some info about tesla and resistors. also the left led is only lit when coils are connected wrong direction or resonation failure.

Doesn't work. The 2nd LED doesn't light on, there are no shorts and everything is soldered properly, I've checked the resistance and both coils seem to function. The 2nd transistor heats up very quickly. Using 19V

Q:
I've put everything onto the board, I've checked many times but I don't see any error in my assembly but it doesn't work. Led 2 lights up but not led 1 and there is no electric arc, help me please.

Das ändert sich immer wieder mal wo die Produkte lagernd sind. Wenn bei "Versand von" Brasilien als Auswahl möglich ist dann kann es auch von hier verschickt werden.
Sonst nicht.
