Hi All,

Here are some more images, comments please.

Hi Earl,
thanks for drawing this up.

I think he used method B
to make his glass beads.

I wonder, if this also workswith just for instance
3 big 12 Volts batteries in series.

Should do.
Probably the sawtooth waveform is only coming up,
cause the arc is almost a shortout to the power supply
and that way he is loading the power supply too much,
so he sees the ripple, which normally loads up the end capacitor
in the power supply.

The more inductance and lower resistance the choke coil
has in front of the arc,the better it will work.

Back when I experimented with my Newman coil with a series stack
of 9 Volt batteries giving me 2000 Volts and the circuit B , I could
draw an arc of about 2 or 3 cm ( about 1 inch), before the arc stopped,
when I pulled the croco clips more far away.

With lower voltage is also work for instance with a transformer primary
coil, but then the arcing dinstance is less.

wow, two to three cm, impressive. I know that voltage struggles through a 1mm gap at 3000 volts, im impressed you got so much more, perhaps this is because you were extending an already ionized plasma arch. I will try number 2, as I believe this is what our friend was doing. Looking at number 3 I think that you would need the to leads of the MOSFET in series with the bead and the battery, and have the base connected to a signal generator put on a square wave or "pulse" mode, whichever gives you the fastest rise and fall time. I imagine though that pulling the contacts appart represents the quickest most abrupt disruption, but it can only be repeated maybe once per second, and im impatient.

I saw two microwaves by the dupster, im goin diggin for trash gold.....take it easy all.

oh I see what you are doing with the MOSFFET, never mind what I said

Hi, only for understanding:

Some of us are always talking about BEMF, isn't it more a collapsing magnetic field effect ?

Sorry for this stupid question, but i think BEMF and a magnetic collapse is not the same thing...
please somebody enlighten me
