This compact Tesla coil creates visible temperature, pressure plasma and delivers several interactive demonstrations in one unit. It produces bright electrical arcs, lights fluorescent lamps at a distance, transmits power wirelessly, and functions as a plasma speaker for lowvolume music playback from a phone or computer. The device is designed for handson science exploration and visual demonstrations. Key benefits Eyecatching visual effects: produces beautiful arcs and plasma that make concepts in electricity and electromagnetism easy to demonstrate. Wireless power demonstration: lights fluorescent tubes in the air to show wireless energy transfer in a clear and tangible way. Audio demonstration using plasma: acts as a plasma speaker by modulating an arc to reproduce music from external devices, adding a novel audio element to demonstrations. Educational and entertaining: multiple modes let students and hobbyists experiment with electrical discharge, resonance, and plasma physics. Main features Arc generation: a tail wire produces visible arcs when powered on. Air lighting: can light fluorescent lamps held near the coil without physical connection. Music playback: accepts audio input from mobile phones or computers; sound level is low, suited for quiet demonstrations or closeup viewing of the plasma effects. Wireless power transmission and plasma effects: demonstrates principles of voltage discharge and energy transfer. Electrical and operational specifications Voltage input: 1224V DC Current: 2A Note: device dissipates significant heat during operation; the heat sink becomes hot. Use scenarios Classroom demonstration: illustrate concepts such as voltage discharge, resonance, and wireless energy transfer for physics or STEM classes. Lab or maker space experiment: integrate into handson projects that explore plasma behavior, electromagnetic coupling, or audio modulation with a plasma speaker. Nighttime or stage effect for small events: create a controlled, lowvolume visual and audio display during darkened demonstrations. Important operational notes and precautions The unit produces temperature, pressure plasma and voltage arcs. Keep a safe distance from the arc and do not touch exposed conductors during operation. The heat sink becomes hot while running. Avoid direct contact with the heat sink and allow cooling time after use. Keep the device away from sensitive electronic equipment and flammable materials. Use only within the specified input range of 1224V DC and 2A. This Tesla coil provides a compact, multifunctional platform for visual and audio experiments with plasma and wireless power. It is intended for supervised educational and hobby use where proper care and precautions are observed.
