Wireless Bluetooth Tesla Coil Speaker - 110V Arc Plasma Science Experiment Kit

Specification: 1. Voltage: 110V 50/60Hz 2. Watt: 0-120W 3. Arc length: 0-10cm (adjustable by rotary switch) 4. Host size: 106*106*58mm Package Includes: 1*Coil 1*Adapter 4*Neon Light Bulbs Red 1* Discharge Needle 1*Instruction Manual 1*US-Plug Upgraded version: 1. Increase to 2 capacitors 2. Optimized the circuit assembly structure 3. The slow start circuit is not bad for fast plugging and unplugging ((Quickly plug and unplug the power supply three times, if there is sparking, it is an inferior product) 4. The volume of the equipment is increased by 40%, and the effect is even more explosive! Stronger heat dissipation performance, maximum power support for one hour of continuous work, comprehensive protection and durability. 5. No special power supply is needed, it supports 110V power supply, and it can be used directly after plugging it in. Feature: 1. This music Tesla has wireless transmission and speaker functions, which can light up gas tubes and various bubbles. It is the perfect teaching tool to stimulate students' interest in science and makes a great gift. 2. It is an intelligent device for wireless transmission experiments. It can be used to manufacture high-voltage lightning, conduct various scientific experiments such as wireless power transmission, wireless lighting, and insulator withstand voltage test. Teachers use it to demonstrate the principles of boosting and high-frequency skinning to students. Effect etc. 3. This music Tesla has a circuit protection design, which will not damage the input device, and the quality of playing music is better than that of ordinary curved plasma speakers. 4. BT connection, convenient and quick. 5. Using a newly designed PCB circuit board, the circuit design is reasonable.
