Tesla coil using simple Slayer exciter

I blame the neighbour he said "how about building a Tesla coil" l have to admit I had thought about it in the past but the gauntlet was thrown.

This is the simplest method I could find being a single transistor oscillator which is basically a tank oscillator but with the tuned or resonant circuit attached to the base of the transistor. The other thing is that the secondary is only attached physically at one end the other end (top load end) is connected via capacitive coupling which is essentially what this divice demonstrates so well.
Tuning is a real issue with Tesla coils (usually ) but this desighn only has a tuned secondary which dictates what frequency the oscillator works at. This makes the thing self tuning.

Having said that it is a simple circuit it is very capable and if you are not careful you can easily get a nasty burn.
This device can also damage electronic devices if you have a pacemaker or any other medical equipment don't use this thing.
I can not accept resp
