you guys are awesome could of used your help about a million times with my make Ghost rider Bike run I had motor chain Battery but you thing I could find a PWM that worked Modulated power by giving a push and a make shift switch where I controlled surges of full voltage. The Fire was a trick as well. check out vid of Ghost rider on fire driving into parking lot. Oh and please vote for it in Halloween contest and villains contest.

Sure is! That transformer was pulling so much current that it was burning out the MOT's they were using for current limiting, lol.

WOW!  Never thought of that one.  Will have to dig out my Tesla Coil some time and try it.  Not sure if it has enough power to make the pendulum swing around like that, but it's a really cool effect.  Haven't used it in years, not sure if it still works.  Kind of suspected that it had something to do with computer (and a few other things) failures back in the 486 days.  Probably do it outside this time, been meaning to, since I ran some outdoor outlets a few years back, just never got around to it.

Yeah, They actually have another video that describes how it works, and set one up using a neon sign transformer. I'll embed the video here. Good luck with your Tesla Coil, Don't let it make your computers let out their magic smoke, haha.
