DIY Mini Plasma Horn Speaker Music Tesla Coil Space Lights Kit Science Experiment Technology Electronics Educational Toy

What is theTesla coil ?

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 but low current. High frequency AC power.
A Tesla coil consists of two (sometimes three sets) coupled resonant circuits. 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.
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. It can be connected to the mobile phone, mp3, computer audio input. The actual experience of this mini Tesla arc plasma speaker is compared with The high-frequency frequency response of the traditional speaker sound is better, and the plasma speaker has better sound quality, stable and safe, can play any music without grounding, and is convenient to use. It can be used as a home audio player. new member!
Principle of wireless transmission: use one end of the coil to connect the LEDs at both ends, close to the transmitting device, the LED will be illuminated, the principle is resonant wireless transmission.
Fluorescent lamp illumination principle: The Tesla coil secondary emits high-intensity electromagnetic waves. When the inert gas in the lamp tube is ionized under high voltage, a gas conduction current is formed, and the moving gas ions continuously give a collision with the mercury atoms. The energy of mercury atoms makes the extranuclear electrons of mercury atoms always transition from low orbit to high orbit. After that, the extranuclear electrons of mercury atoms spontaneously re-evolve from high orbit to low orbit in the form of photons. The energy is released outwards, and since the atomic characteristics of the mercury atoms are mostly concentrated in the ultraviolet region, it is known that most of the photons emitted by the mercury atoms are in the ultraviolet region, and the high-energy ultraviolet rays generate white light between the collision with the phosphor. (or other color light, depending on the phosphor color).
  • Size: 38*79 mm
  • Power: 15w
  • Power input: DC 15-24v, current 2A, DC5.5 interface
  • Audio input: 3.5 jack, can be connected to mobile phone, mp3, computer audio

This product is a spare part plus power supply, you need to assemble it yourself.

  • This Tesla adds a music player function to the ordinary Tesla: a new concept speaker that the arc excites the air to become the air vibration generated by the plasma! You can play mobile/computer music with clear sound. The voltage input is 15-24V DC, the arc length is 24V, the optimum is 5-10mm meters, the volume is small, the work and energy are complete, the machine can work continuously for a long time, and the LED can be lit up by the air, the foam energy-saving lamp, the flash frequency Tube, you can play radio transmission, rotating arc, etc.
  • 1, this product is safe, power is not high, will not be injured by electric shock, but it is not recommended to touch the arc at the top of the coil, there will be a burning sensation.
  • 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, the fan interface is reserved, 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 as good conductors will make the coil form a good loop, absorbing the coil energy, making Tees Pulling the coil at this time shows that the effect is worse or cannot be demonstrated! 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!

There might be some deviation due to manual measurement.

DIY parts purchase notes:

1. There are many types of components in the parts. If there are few small components in the package, I hope the buyer can understand, don't give a bad comment because of a small capacitor and small resistance. This is very boring. You say yes, everyone plays electronic This kind of small components will generally be prepared. If there is no backup, find a broken circuit board. Of course, we will try our best to prevent this from happening. If there are fewer devices, we will press this store. The price of the component is refunded. It is recommended that there are no spare parts or buyers with poor hands-on ability to buy two sets of spare parts.
2. If you are concerned about the quality of components, please test them one by one before soldering. Once the solder is soldered, it is impossible to judge whether it is soldered or the component itself is bad. This kit is all new components (there are second-hand kits for individual kits, please see the delivery list for details), but any new components are defective, and there are many spare parts. We have no way to test each, such as poor soldering before soldering on individual components. Please do not reissue the store, only the component price.
3, because each person's level of understanding of components and circuits is different, welding technology is different, so the store does not guarantee that all people are successful in production, DIY baby does not accept quality problems return, whether the things made with the baby description Depending on the level of personal production and debugging capabilities, if you want to successfully solder or require 100% soldering success, please bypass.
4, after the tin or cutting does not provide return service, if you encounter problems in the process of production or use, you can send the materials back to the store, the store will try to help repair, the return shipping costs are borne by the buyer.
5. After welding, please self-test, if the welding is not wrong, generally it can be successful. If the welding fails, the store is not responsible, we can not guarantee that you are 100% successful, but we promise to do our best after-sales service and do our best to help all friends. Finish the production. Therefore, when encountering the finished product does not achieve the effect we have described, please do not rush to give us an evaluation, remember to contact our after-sales service.
