Tesla coil with audio modulation. The streamer reaches a little more than 1 cm, there are 3 test bulbs in the kit – they glow in the air without wires – 2 miniature neon lamps, and one big one (SG2S or SG3S, at the request I can put IN-15).
It is made on a transistor circuit, powered by + 24 V, a power supply of ~ 220V is included. Also included is a rotating tip for creating an ion engine.
Great for entertaining shows, high voltage home experiments, school and university experiments.
