Tesla coils are always a hit around here at the office. Giant ones that play music with modern-day chain mail wearing DJ’s, ones thrown together in garages by self-proclaimed mad scientists… But have you ever seen one that can fit in the palm of your hand?
[Ludic Science] just released this tutorial video on how to make it. It’s a miniature solid state Tesla coil that’s based on the ever popular Slayer Exciter circuit that was first developed by [GBluer]. The beauty is it’s a very simple circuit to build. It consists of one power transistor, a few diodes, some resistors, and the coil. That’s it!
He even repurposes the magnet wire from a small relay, it’s literally a project you can build from scrap parts around the shop. Awesome.
One of our favorite Tesla coil builds has gotta be [JJ Dasher’s] ridiculous Halloween setup. He goes all out. And if you do ever want to build one on a macro scale, you might need this auto-coil-winder.
