This product is a mini music Tesla coil DIY assembly kit. It’s a high-frequency, high-voltage experimental device based on solid-state SSTC technology. The kit is shipped as a complete assembly; users solder and assemble the circuit board themselves. When powered on, the metal pin at the top can produce a cool purple electric arc. With a Bluetooth module, the arc will rhythmically dance to the music when connected to an audio source, visually demonstrating electromagnetic induction, high-frequency voltage boost, resonant discharge, and other high school physics principles. Suitable for electronics DIY enthusiasts, high school physics classes, university electrical engineering training, science exhibition exhibits, and desktop decorative items.
Product parameters:
Product model: YH-701
Power supply voltage: 48V (DC)
Product dimensions: 167*92mm
Core product selling points:
1. Visualized arc + musical rhythm: intuitively experience the principles of high voltage physics
Two engaging effects of the finished product:
① Static Arc Discharge: A 5-8cm purple, forked lightning arc can be drawn even under no-load conditions, replicating the form of natural lightning and visually demonstrating the Tesla boost resonance principle;
② Musical Arc Effect: Connect to a phone/computer via Bluetooth to play music. The arc expands and contracts in sync with the beat and pitch, dancing to the rhythm, with synchronized sound and light, creating a highly futuristic atmosphere.
2. Complete DIY assembly of disassembled components: master high voltage circuit knowledge from scratch
The entire board consists of discrete components. Partition identification, soldering, circuit troubleshooting, and power-on debugging are all required. Learn physics and electronics concepts such as LC resonance, high-frequency inversion, electromagnetic boost, and audio modulation through hands-on practice. It is an excellent teaching tool for high school physics extracurricular activities and university analog electronics training.
3. Solid-state SSTC safety optimization, beginner-friendly and less prone to board burning
Utilizing a solid-state transistor inverter solution, abandoning the old-fashioned spark gap structure, the circuit features built-in overcurrent and reverse connection protection circuits. Low-voltage DC power supply significantly improves safety compared to traditional oil-immersed Tesla coils. Beginners can easily connect and debug according to the tutorial, minimizing the risk of component damage from accidental operation.
Power Supply: DC low-voltage input, compatible with a standard adapter; no additional high-voltage power supply required.
4. Dual-mode compatibility: bluetooth wireless + wired audio input
Bluetooth Wireless: Built-in Bluetooth 5.0 module; one-click pairing with mobile phones and tablets for wireless music playback to drive the arc.
Wired Input: A 3.5mm audio jack is provided for connection to computers, media players, and mixing consoles, suitable for science performances and classroom demonstrations.
Precautions for use:
1. Do not touch electronic components while the product is in operation.
2. Keep away from mobile phones, computers, etc., as surrounding electronic devices may generate electromagnetic interference while the product is in operation.
3. Do not place flammable or explosive materials nearby while the product is in operation.
4. Minors must be supervised by a guardian when using the product; keep away from individuals with pacemakers.
