Re: mini TC/plasma globe
Hi.
I guess you just need a larger glass globe, like a chemistry cooking ball.
Another solution is to use a string of resistors to build a, say, 10 Mohm
resistor that will stand your 10 kV: put that in series to the HV cable. It
will
limit the current and reduce the shock effect.
Check my plasma globe at http://www.saunalahti.fi/dncmrc/pglobe.htm. That globe
doesn't zap.

hello everyone, I built a mini coil from some junk I had laying around it
uses a the primary power supply is made from a mini flyback from a portable
b/w TV it gives me about 10kV when i use a 555 driver circuit after I
finished putting it together I fired it up
and got alot of O3 no streamer though but I did not think I was going to get
any,I could draw 1" sparks to my fingers so I decided to put a clear light
bulb on it and I got plasma discharge(not very intense)but when I touched the
bulb I got zapped right through the glass.this now leads me to my
question...why did it do this and can I stop it? I would like to perfect
this and make it a display but with the arcs coming through the glass I not
to sure if I should and the O3 could be a problem I got a headache and a
upset stomach after just five minutes.so if any one has any comments or
suggestions please let them fly.
thanks to all in advance,
