Hi,
I am studying about tesla coils for my project at university, i was wondering if you could give me some information on how to build and also the theory?
Richie Burnett's site is a good place to start.. he has a bunch of
background info and such.
Older literature (say, before the 90s) will often have practical
dimensions but use components or techniques that have become obsolete.
Very few people wind their own foil/poly capacitors these days, since
the advent of the MMC (multi-mini-capacitor) approach.
There is also a persistent (and incorrect) design approach based on the
length of the wire wound in the secondary. Basically, it just happens
that in most practical coils, the wire winds up being close to a 1/4
wavelength in free space of the operating frequency. Turns out that
that this is mostly happenstance (convenient sizes of wire and forms,
mostly), and lots of other lengths also work.
