Mini Tesla Coil Schematic

The ignition coil is not portrayed as connected to the driver circuit but it is shown clearly where to connect in the schematic of the tesla coil itself.

Mini tesla coil schematic.

Circuit of coil as you can see it s very simple and we need only few components. This is mainly because of few subtle mistakes that commonly occur. This is a very cheap mini tesla coil made of stuff i had lying around. To understand better let s define what is a radio frequency oscillator.

When this voltage is high enough a spark jumps across the gap and allows c1 to discharge into l1. It is used to produce high voltage low current high frequency alternating current electricity tesla experimented with a number of different configurations consisting of two or sometimes three coupled resonant electric circuits. Electricity flows into c1 until a high voltage is seen across g1. A tesla coil is an electrical resonant transformer circuit designed by inventor nikola tesla in 1891.

It is also essential that the 6 volt power source is separate from the 12 volt one that is why there s a photocoupler to completely isolate it. Power supply 9 21v also it s gonna work from batteries with same voltage little heatsink transistor 13009 or 13007 or almost any npn transistors with similar parameters variable 50kohm resistor 180ohm resistor cooper winding wire 0 1 0 3mm i used 0 19mm which is 36 american wire. This electronic oscillator produces signals in the radio frequency range of 20 khz to 100 ghz known as a radio frequency oscillator.
