Coil Module DC 12-24V 15W – Plasma Speaker Arc Generator Kit for Electronics Experiment, Music-Driven Spark Display with 3.5mm Audio Input

This coil module is a DIY assembly kit designed for electronics enthusiasts and educational demonstrations. It generates visible plasma arcs for experimental visualization and audio-modulated effects, providing hands-on learning in electromagnetic principlesConnect the module to a DC 12-24V power supply (2A current required). Use the 3.5mm audio input to play music – the arc will synchronize with sound frequencies. For light barrier experiments, place fluorescent lamps near the arc zone. Always maintain 10cm minimum distance from arcs and operate in dry, ventilated areasSpecifications:Item Type: Coil ModuleMaterial: Synthetic CardboardPower Input: DC 12-24VPower: 15 WCurrent: 2AInterface/Pin Audio Input: 3.5 SocketCircuit board color: GreenCircuit board size: 40 * 80mm(1.57 * 3.15in)Package List:1 x Coil Module with LED LightNote:1.
