Joshua-
I have a really good set of plans for an induction coil. In fact, it was
designed by Tesla himself. It features a really compact design, magnetic
sheilding, and spark output of at least 10cm on either terminal. I'll be
uploading the files tonite, they can be found at:

If you get a 404, just check back later. It should be there by at least ten
tonite.
 This coil can be driven by spark interrupt, or high frequency switching.
For high frequency switching, just add a feedback winding, and use a high
power mosfet circuit. (see alan sharps webpage)
Good luck,

-Michael
