Ideas for creating a portable Tesla coil Answered
I am in the process of planning a small-ish Tesla coil that can fit inside of a medium-sized hard shell suitcase. I would like to be able to power it without using a wall outlet, which most likely means with 6v lantern batteries or 12v lawnmower batteries, but if you have any other suggestions I'd be glad to hear them. I would prefer to keep the coil as simple as possible and maintain a spark gap configuration rather than a solid-state one because I am not very good at soldering small parts. I was thinking about using a neon transformer from a set of car under lights such as these http://www.amazing1.com/profneon.htm (is there anything there which would work especially well?) or perhaps a modified ignition coil with a mechanical interrupter, similar to a Ruhmkorff coil (I have no idea how I would do this, but it sounds like it would work). Your thoughts? Also, instructions on how to construct a flat 'pancake-style' secondary could be beneficial.
