Negative resistance via pyroclay.com material ?

I think we all know its easy to get a little hot under the collar with sensitive issues, I think sometimes it just takes an impartial observer to set things back on track.

I think you mean well, as does linda, as do most here, that pretty much the bottom line.

@All

I have been gone and in the meantime, I received some pyroclay sample.

I have some other things to do first, and my computer has some problems, so there will be a delay until I have time to try making some beads.

@RadiantNRG

Please your comments about the following circuit.
If you do not like the circuit, please suggest changes.

It needs to be a pulsed circuit. The battery supplies a straight shot, and you want either a square wave or a saw tooth wave. The abrupt changes make a reverse EMF that is really powering the load. Making the crazy green light. A motor/switch would work...but there is heavy losses in the switch. I would recommend a 555 astable circuit, or a transistor setup...where a sensing loop, of about 5 turns be wound on microwave xformer, or around motor, and that triggers transistor. If you go with a 555, alot of tuning will be needed, and it is very dificult/impossible to tune it "on the fly"

@RadiantEnRg
How did you make your pyroclay bead conductive?

@AhuraMazda
Plasma arc fuming of metal contacts...Stainless steel clips....some of the stainless transfers and makes layers of FeO2 and CrO2 and there is the addition of the SiO2....there is an intense localized heat...So I am assuming that oxides are the compound be made.
