Create idea 2set Coil Speaker DIY Mini Transformer Kit DC 15-24V 15W Compatible With Tesla Coil Plasma Speaker Wireless Transmission Compatible With Tesla Coil Module Soldering Project Unassembled

The coil in this kit is a transformer (resonant transformer) that works on the principle of resonance and is mainly used to generate high-frequency alternating current with very small current. The kit also includes a music playback function: the new concept speaker uses the air vibrations generated by the arc to play music through the 3.5 mm jack. The finished kit produces an impressive plasma arc that glows and can be ignited. Note: This product is an electronic kit that still needs to be assembled. Soldering skills are required for this! All necessary circuit board components are included in the kit. This product does not use high currents. You will not be electrocuted if you touch it, but there is a risk of burns if you touch the arc! In addition, the heat sink will also heat up after being powered on for a long time. In 15V-24V operation, the radiator will become very hot after long-term operation. In this case, we recommend using a small fan.
