Negative resistance via pyroclay.com material ?

having no success and getting a little frustrated (maybe this just takes a loooooooooooooong time) I decided to cheat and see if I could make a bead with just fire, well it worked, so at least im not barking up the wrong tree.

I am going to try a different method and see what happens

I am going to take some fine copper dust, mix it with the silica, and create a bead over a flame.
To get the same effect, I plan to create the bead on sharp rod connected to the tazer, and have the other output of the tazer directly across from the first, without arching, this should align the molecules with the field while the bead is crystalizing from the cool down process. should be interesting. ill let you all know how it goes.

Hi armagdn03,
I guess you are using way too high voltage and too low amps.

You really need to use higher amps and lower voltages
like in a welder device so around 30 to 50 Volts and at least 2 to 10amps.

If you use such a power supply as user RadiantNRG has used,
you need to put a big choke or transfomer winding in series
to get the arc still going, after you pull off the contacts.
This high inductance L keeps sure, that the arc keeps burning
due to the BackEMF jumping the arc, when you pull off the contact.

So you need at least to have around 30 to 100 Watts of power to do this, I guess,
so his powersupply with 30 Volts and 3 amps maximum had probably around 100 Watts
maximum power output.

Your Stun-Gun is not built for these high wattage and the high voltage will
play only games via the ion wind with you.

Ok...there seems to be a lil confusion as to what actually makes the beads. The diagram Earl showed is correct....however thats just how to use the bead not make it. (And yes Earl it starts up instantly...and will melt the bead until the motor commutator takes over as resonant spark gap).

This is what is crucial to making it....VERY sharp off pulses...the power supplies that worked did this....  /|/|/|/|/|/|/|/|....slower rise time....almost instant off time....this makes a VERY STRONG BEMF...after all faster the delta time (change time) the higher V you get....I would say just make a 555 pulse circuit that operates an optoisolator...which in turns triggers a MOSFET pulsing 30v...in all my test 30v is good. The mechanical switch I made in my "Odd" youtube video is getting the arc...it's all about the BEMF,,,,input=30v....BEMF=1000's of V...theoretically infinate if instantaneous can be achieved

SO just to be clear....no pulse charging of a cap is needed.....all you need is a coil...the collapsing field is what makes the ARC.....The ADP series power supplies work like this...the use rectified 120VAC to charge a large capacitor....then use that capacitor and step i down through a xformer....which then charges a smaller cap....that smaller cap is pulsed by a transistor which is triggered from a sensing coil on the xformer....Once I coax out the initial arc....there is a trail of ionized gas which conducts the following on pulse...which then is shut off and another HUGE arc pulses back...ect

Hi RadiantEnRg,
could you please show again in a longer video with all details
and all connections shown and also putting on your scope, how
you run the motor faster with the bead ?

Please show then the output voltage at the power supply on the scope
and also the voltage on the motor.

Many thanks in advance.

Regards, Stefan.

Actually I think you misunderstand what I first did before the stun gun. I was "pulse charging" the cap to get a large energy buildup, im sure you all know amperage being a a function of time means that a discharge over a short period of time equals extreemly high amperage.....like in a point contact welder. 
but I did have a large coil hooked up to it.........my electromagnetic can crusher,.. but still the pulses are quite short, ill try something else though.
