Introduction: Kacher Brovina (Mini Tesla Transformer)
This is called "Kacher Brovina" miniature Tesla transformer. The generation frequency to 10 kHz at a voltage at the output of 6-10kV. The scheme represents a primitive blocking oscillator. 12 volt power supply. Sorry I do not speak in English, write a translator :) coil is wound on PVC pipe, wire 0.125 mm in 1000-1500 turns. secondary coil 3 - 6 turns of wire of 1.5-2mm, 12-volt motor, miniature. inside the circuit with the first figure.
We have a be nice policy.
Please be positive and constructive.
