Tesla Coils / A Scientific method with Slayer Exciter

You can build a very powerful Tesla coil that will not destroy itself. You can do it right by learning how the Slayer Exciter actually works and the various ways that it can "blow up".
You will learn how to determine the frequency at which the Slayer oscillator will run before you even build it.

Tesla coils are dangerous. Please heed the warnings in this video.

This video contains some useful information, but also some incorrect information. Paralleling transistors does not cause them to share the current (the transistor with the highest gain wins). The output voltage is not equal to the turns ratio times the supply voltage. It is the collector voltage not the supply voltage that matters (this is the voltage across the primary coil), and as you see in this video it does no good to increase the supply voltage once the collector voltage reaches the voltage rating of the transistor. The only thing the top hat does is tune the coil to a lower frequency.
