Product description format_size zoom_out zoom_in

High-voltage high-frequency generator with Tesla coil and the ability to modulate a high-voltage arc with an audio signal from a phone, computer, player, etc.
At the output of the coil there is a fairly high voltage, but a very low current, as well as in combination with a high frequency ( Skin effect ) makes this device safe to touch. The arc at the maximum supply voltage does not exceed 5-10 mm. When modulating with music, it should be borne in mind that the sound will be quite quiet. To increase the volume, the arc can be directed towards a thin-walled horn, thin plate, or soda can.
Assembly requires skill in assembling electronic devices and assembling printed circuit boards. The ratings and locations of the parts are printed on the circuit board. Connect the coil at one end to contact J8. The direction of installation of the spool is indicated on the spool itself. The coil must be glued to the board along the outline on the board. With the wire that comes with the kit, you need to make one turn around the coil and solder to the 1T holes.
