Operating within a DC 12–24V range and delivering up to 15W of power, this compact yet powerful device produces visible electric arcs while also functioning as a unique plasma speaker capable of playing music through air vibration. This Tesla coil module allows users to connect audio sources such as smartphones, computers, or MP3 players via a 3.5 mm audio interface, transforming electrical discharge into sound waves. In addition to its audio capabilities, the device can wirelessly light fluorescent lamps and demonstrate electromagnetic field effects, making it an excellent educational and experimental tool. Designed for DIY assembly, this kit is ideal for users with basic electronics knowledge who want hands-on experience with circuit building and Tesla coil technology. Its compact board size and modular structure make it suitable for workshops, STEM education, and personal projects. Due to heat generation during operation, proper cooling and safe usage are recommended for optimal performance and longevity.
