Paul, That's a really good point!. I use neoprene covers over the EHT part of the microwave, when I'm working on them. I remember making a Jacobs Ladder out of a microwave oven supply and a few other bits, and it worked well, until the ladder wires shorted together. Won't be building one of them again, for a while, anyway!.
There have been quite a few Tesla Coil projects in the American electronics press in recent years, as well as companies marketing kits for Jacobs ladder type experiments.
Bill, Now, that is flash, mate, Love a good joke like that. We need more of this sort of humour at ECN, we all love a laugh, just takes the doom and gloom away from the working day!. Just a shame, I haven't got a Digital Camera, for submitting offences, of course!.
