Feature: 1. Tesla Includes Music Playback Function: A new concept speaker that generates air vibration and sound from arc excited air converted into plasma Can play mobile phone and computer music, but the sound is relatively low, suitable for watching magical arcs and listening to music comfortably in the dead of night. 2. Tesla Arc Generating Function: After being powered on, the wires at the tail will generate an arc, which is beautiful and gay. 3. Tesla Vacuum Lighting Function: After the Tesla coil is powered on, it can light up the fluorescent lamp in a vacuum 4. Heat Dissipation: The heat dissipation during operation is relatively large, so the heat dissipation fins are relatively hot When using, be careful not to touch the heat sink with your hands. 5. Functional Parameters: Voltage input 15‑24V DC, current 2A. Many component parameter optimization experiments have been carried out in the circuit development to ensure excellent results.
