A simplified version of the Slayer Exciter solid state Tesla coil using only a 10F supercapacitor, a 2N3904 npn transistor and an 85 turn coil.
It requires an electromagnetic pulse to start resonating at very high frequency.
The larger model uses a 2N2222 transistor.

Rechargeable Portable Spark Gap Tesla Coil for Science Demonstrations

This coil was inspired by a build by Jay over at the Plasma Channel on YouTube https://youtu.be/4GRyxuRIPPo

I began this adventure while attempting to rebuild a tabletop spark gap Tesla coil I previously used in demonstrations at some Maker Faire’s. That coil was a basic spark gap coil using a 12 volt power supply, a television fly-back coil driven by a ZVS circuit and hand rolled high voltage capacitors. My primary goal was to make a small and safe (table top sized) spark gap Tesla Coil with an integral and rechargeable power supply to use for demonstrations at a local science museum as well as in classrooms at local schools.

Since I achieved my primary goal, my new goal is to provide the information for anyone to build a similar coil, including how to change design parameters based on what resources they have available.

I will be posting links to all files and resources used to build this Mini Tabletop Tesla Coil Powered by an Arc Lighter.
