Sorry all @@. I'm done with slayer exciter. Thanks for your advice. I'm just searching something more like tesla coil actually.

 

I was just going through the thread and the comment about an "RF burn" got my attention. I once got a small RF burn across part of my finger tip when I touched a resistor to see if it was hot. The arc across my finger tip smoked a small patch almost instantly. It was very educational indeed. That was back in 1964, and the memory is quite clear today! Some lessons stay with us very well.

A real Tesla coil would take more effort to assemble than what we saw in the picture, but a working version would be an exciting thing indeed. An exciting alternative would be an electric fence charging device built using an older style automotive ignition coil to deliver the high voltage. I saw one of those delivering noisy sparks over an inch long. It was definitely not a harmless toy, but certainly impressive. BUT getting that high voltage coil may not be so easy in some areas of the world.
