Negative resistance via pyroclay.com material ?

A little story to explain some things to younger people.

When I was fresh EE graduate a long time ago, I moved to my first job and asked a newly made friend if he could lend me a power supply so I could align an FM transceiver that I was converting from commercial to Ham radio use.  This friend was a top-notch Engineer with decades of experience and also a Ham radio operator.  After a while I became very frustrated because the normally simple alignment was giving me a lot of problems.  After quite some time, I came to the conclusion that at certain voltage settings his power supply was oscillating and even worse the frequency was around 455 kHz exactly the IF frequency.  He was extremely embarassed, but I rubbed it in anyway, since a really good Engineer would have put a small resistor or ferrite bead on the base of the series pass transistor.

I know of another case where a young Engineer designed an audio intercom system that was used overseas on a top secret project.  Lo and behold, the intercom was oscillating in the FM radio band and all conversations could be heard on a normal FM radio.  So you can see, whether young or old, you can always learn.  I am an elder and I learn many things every day, in spite of 40+ years of professional engineering experience.

Dear RadianNRG, please do not take any comments as being negative, any criticism is positive and is meant to help and clarify the situation.  Maybe you think older, more experienced participants and Engineers are old foggies and don't understand.  I hope the above examples will make it clear that we are all working for the same goal and trying to multiply our individual intelligence through co-operative discussions on a non-emotional, intellectual basis.  There is a big difference between negative criticism and positive criticism.  I have seen absolutely no negative criticism in any postings.

Perhaps one of the most important things I have learned over the years, is that you are blind without an oscilloscope.  You can make a quickie measurement of a power supply with a multimeter, but you should be aware that this does not tell you very much.  In this particular case, only an oscilloscope will show if the regulated power supply is oscillating due to external influences.  An Engineer without an oscilloscope is like a pianist without a piano.

Having a couple of batteries around is always a good idea.  One time I was breadboarding a linear RF fiber optic prototype and was having problems.  The RF preamp had about 40 dB gain and the fiber optic link another 15 dB, at the same frequency and from the same power line.  I disconnected the power to the preamp and powered it from a battery and the problem disappeared.  An additional RF choke and by-pass capacitor in the RF preamp solved all troubles. 
I bought a couple of auto accessory 7Ah battery packs with cigar lighter jack, modified them with additional bannana jacks and keep them charged up.  One for 12V or two in series for 24V.  They come in very handy; would not like to be without them.

In any case, my sample of pyroclay should arrive sometime and I will try a few experiments myself.  Houston, we see molten lava down there........

@ linda, he had an earlier post where he showed how he hooked into the power supply, and I do believe he bipassed the smoothing capacitor. could be wrong though

[RadiantEnRg]

In later tests I bypassed the smoothing cap and used pulsed rectified DC(thats why it fried)...However, in all of my videos(the original ones) I used the actual output, which never saw anything more then 27V, due to stepdown xformer. Also the max amperage was 2amps....the voltage has a limit, and it seems the only thing I could "de-regulate" was the amperage, because it was only suppose to supply .87amps. So to just clarify, pulsed DC power supply, /|/|/|/|/|/|......and coil, thats and a lil manual "coaxing" is all you will need to tap BEMF potential.

Hi All,
I just tried this with just a battery.

I had 8 pieces of AA MiMh cells in series with a total of 11Volts freshly charged.

So then I used a few different coils in series with this battery and going to
a 12 Volts DC motor.

I then used different contact materials like pencil graphite ( which has clay in it !)
on copper or pencil graphite on iron or copper on iron, etc...
but always the direct connection did make the motor run
faster and when I drew an arc at the contact point,
always the motor did run slower,
cause much of the energy was then used up in the arcing
putting out heat and RF energy.

Okay, I didn?t try pyroclay cause I don?t have it,
but now I believe, user RadiantNRG has just jammed his
power supply with the arcing and thus it produced more
output voltage.

Please user RadiantNRG try it yourself again with a 12 Volt
battery and let us know the results.
If you don?t have a 12 Volt battery and don?t want to buy one.
well, at least try to get from somewhere a Kill-a-Watt meter,
so you can measure the input power into your power supply
and see, if you heat the pyroclay bead and your motor runs
faster, if you draw also much more input power ?

As long as these tests have not been done, one can really not say
anything about this...

Now I am going to try the other circuit with the transformer pulsing...

I agree completely.  It seems like so many of these stories start out claiming one straightforward effect that seems anomalous but by the time four or five posts are made, the story has branched out so many ways with so many added elements, new conditions and various theories and arguments that the original idea is lost in a fog. 

Science moves in little steps, each one carefully stripped of all presumptions and assumptions.  Every step involves testing and observing and trying to explain the observed results first using known conventional phenomena.  Here, in most cases, too many variables remain undefined and non-conventional conclusions are leapt to without ever even stating the setup and observations clearly.  It's impossible to replicate such undefined experiments, not to mention pointless. 

I still don't know what the original setup was on the "speeding motor" experiment and I don't think any two readers share the same vision.   I don't think there was an external coil in it, was there?
