With apologies to Steve Martin, I was hoping to inspire some discussion on
the small end of the Tesla Coil spectrum. Not to suggest it's easy but
everyone knows if you throw 10KVA into a coil, you're eventually going to
get some big sparks. Not much has been shared about the other end of the
spectrum.
Several years ago I threw together a palm-top sized coil powered by a yard
sale bug zapper transformer. Bug zapper transformers are built just like
NST's, current limited but tiny.
there's also the GMHEICSLR one can work on - basically driving a GM HEI
ignition coil off 110V line.
1 foot sparks are possible..
http://www.powerlabs.org/gmheicslr.htm has a story by Sam Barros from
2010 illustrating his ideas. Sam has moved on to other things (if you
need your GT-R tuned or enhanced, he's a guy to talk to), although I
suspect he might have his old coils laying around.
