I started the day badly. My secondary earth wire touched the inside of my secondary. 1/4 hour with emery paper and a sanding wheel, the coil was back working.

Ready for Demos.

My AD-OLTC entertaining the crowd with a rendition of Twinkle Twinkle. (Mental note, must change the tune!!)

I blew an IGBT whilst power arcing to earth, One more defenceles transistor gives it life to the cause.

A member of the public (sorry I didn't get your name), brought his (rather nicely built) ignition coil for faulting.

Martin tries to determine why the output is poor.

Bob Takes a break..

Paul and Dave, sorry if you haven't brought a coil, you get you picture taken instead.

Bob's Coil , being set up.

About 4' sparks from a "wizards hat" on top of Bob's coil.


Working, About 2.5-3' arcs to air, sparks to ground still blowing OV trip though.

Mike Harrisons Bipolar Marx, Suffering from damp and sawdust, but still giving 3' arcs.

And again..


The "Jacobs laddder-o-phone of death"


Mike descovers a new way of cooking apples. A steel whire through the center and hook it up to the cap bank. Tastes rather metalic though..
