Tesla coil module with music playback and visible arc effects Key benefits Multi functional: plays music from a mobile phone or computer while producing clear sound through the built in music player. Visual and practical demonstration: powers up fluorescent tubes in midair and generates a visible tail wire arc that can ignite small combustible materials. Compact and robust: small size with a wide input power range and output allows long continuous operation under typical conditions. Predictable performance: optimized for 24 V operation with an ideal arc length of 5 to 10 mm. Main features Music playback: accept audio input from mobile phones and computers for synchronized sound and light demonstrations. Air lighting: when powered, the coil can light a fluorescent tube held nearby without direct electrical contact. Arc output: tail wire produces attractive electrical arcs; the arcs are strong enough to ignite small targets. LED effects: unit supports LED lighting and flashing for enhanced visual presentation. Electrical specification: designed to perform at 24 V, producing arcs in the 5 to 10 mm range. Continuous operation: engineered to run for extended periods thanks to power capability and a broad operating range. Compatibility and usage Connects to standard mobile phones and computers for audio input. Suitable for power supplies that provide 24 V or compatible voltages within the supported input range. Practical applications Educational demonstrations: show principles of voltage, plasma, and wireless energy transfer by lighting a fluorescent tube in the air and producing visible arcs while playing explanatory audio. Hobbyist experiments: integrate with audio sources and LED effects for safe tabletop demonstrations and visual projects. Stage and event effects: add synchronized sound and electrical arc visuals for controlled performance setups. What makes it stand out Combined audio and voltage visual features let you demonstrate sound driven effects without needing separate devices. Compact form factor with a wide power range and output enables longer continuous demonstrations and flexible installation. Proven operating point at 24 V with 5 to 10 mm arc length delivers repeatable, visible arc performance. Notes Intended for demonstration and experimental use by informed users familiar with voltage equipment. Follow standard safety practices when operating voltage devices.
