Feature: 1. The Tesla coil can produce high temperature and high pressure plasma, which can sing, ignition, wireless transmission, and light fluorescent lamp. 2. Perfect sound quality playback, playing songs as the highlight of this product, in the development of the circuit to carry out a number of component parameter optimization experiments to ensure that there is a fine effect. In actual use because of different mobilephones or audio sources, volumes the size may vary. 3. Strict production process. Secondary coils use epoxy resin coating, fine durability and beautiful. The use of fine-quality PCB board, as well as carefully selected power tube, continuously improve product technology and quality from various details. 4. Prime structure, the coil part is detachable, the toppart can be replaced with different accessories to achieve different functions, and the CPU heat sink is used as a base, which has a strong cooling capacity and ensures the reliability of long-term work. 5. Beautiful appearance, except the functional value of the product, it also has ornamental handicraft ornamental value. Specification: A mini tesla coil module which can create a high-frequency, high-voltage alternating current and creat electromagnetic waves. It has the function of wireless transmission, can light gaseous tubes and p - lay lot s of songs in a fine quality. It is a perfect teaching tool to spark students' interest of science, also can be a fine gift.
