Getting Started (was Re: Arcs off the fingers... )
My first hint of a Tesla Coil came when I was about 8 and
read about a 1/2 wave horizontal model in a book on spark coils. It
was many years before I got around to building one. Much time and
wire was wasted at that stage in learning about tuning rules. I had no
idea then that sparks could reach many feet or come out white hot.
The description in the book was of "purplish sparks about 3 - 4"
long). The book came from a library and I have no idea who wrote it.
