Mini Tesla Coil Schematic

Tesla used these circuits to conduct innovative experiments.

Mini tesla coil schematic.

To understand better let s define what is a radio frequency oscillator. Primarily we are aware that the electronic oscillator is a device that produces electrical signals of either a sine wave or a square wave. 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 is mainly because of few subtle mistakes that commonly occur.

When this voltage is high enough a spark jumps across the gap and allows c1 to discharge into l1. 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. This mini tesla coil circuit is very simple and just works with a help of 9v battery and very few commonly available electronic components which makes it is very easy to build fingers crossed there are a handful number of people who have tried this project already and have failed to obtain the result. This electronic oscillator produces signals in the radio frequency range of 20 khz to 100 ghz known as a radio frequency oscillator.

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. Circuit of coil as you can see it s very simple and we need only few components. This is a very cheap mini tesla coil made of stuff i had lying around.
