Giantkiller moves forward into Full Heterodyning.

So did you do a little victory dance this mornign when you realized you got the runaway condition......   I sure would have

Yes I did!. But I share the office with my wife, who was in there at the time. And when the smoke curl climbed from the fet into the air and the protoboard melted, well, I was asked if I needed a fire extinguisher. Oops!

The signal started out small then thump, thuMP, THUMP. I sat there in amazement as the electonic circuit rose into the air in a puff of smoke.
That was great but now I need to reproduce it.

If I was using tubes I guess the tests wouldn't be so unforgiving.

I'll do it again.  With this setup It seems to be related to current draw at this stage.

Well we all know the parallel background in the OMG moment. The increasing high speed progression into the greater than before event step.
And before you know it, it's over. Wow. I don't know if I broke anything or it was an anomoly. And I sure didn't want to start any parade or fanfare till I perform this test again. It was late and I am a little burned out. But not giving up. The absolute baseline is the iron wire bars, the magnet blocks, the bifilar copper / steel, the pulsing in the natural way or with the flux flow. This setup anybody can do. There is no magic or turn here.

In addition to the next attempt I am going to try with a 100ohm resistor inline with the coil to see if I can slow this ramp up down a little bit. I am not here to play 'Pop goes the weasel' with FETs.

But I can honestly say this 'The ramp up comes from the saturation process of the iron wire' in this case. I can guarantee that is a major part of the hidden truth we have been looking for. You can see it on the scope and hear it jackin' in the PC speakers. Especially when the wife turns around from her squealing PC and asks 'Is that you? I have never heard that before!' 'Oops'. I replied. 'Yes, dear...'

It just starts bouncing and bouncing and bouncing. This happened at 32hz.
I will get back at it and do it again. But I repeat: This bouncing into some kind of resonancy is something I have noticed many times with this PMH configuration over the last couple of days. This was the easiest coil yet to build. The driver and sense coils are both 40 feet of wire in parallel. Not happy with that? Just pull the collector apart and slip a new coil on. One caveat: You must use the 4" cable ties that lay flay when buckled else the rat shack spools don't slip over them or you can buckle the iron wires in their center and the hold the bundle ends together when you slip on another spool.

--giantkiller. I am happy so far with this.

p.s. Let me reiterate. You can see this bouncing on the timeline axis of the scope. I repeat: You can watch it happen.

Much excitement.   I think in your next mod you should try this-  the trick to the tesla transformer was "even" diametric coils. If your gonna stick wtih the bifilar i would reccomend trying to cover all the green garden wire proportionally in quadrants or sections of even length.  He kept repeating that they had to be equal in all ways so as to preserve the dynamo magnetic induction. I think thats what he called it.  As well im going to the hardware store tomorrow for the parts but i was thinking had you tried superimposing the steel wire on top of the coper wich is on top of the iron garden wire.

  Im wondering what the difference between the bifilar controls you have wrapped on the spools vs covering the quadrants equally with the steel superimposed on top of the quadrant windings in accordance and connected in a series diametric fashion like the patents show.. Also did you say that you hooked up your copper coils diametriclly or in series around the loop? I know taht would make a big difference.   Awsome progress again man.

@LJ,
I saw all the parts and just slammed them together with minimal simitry. I wonder if steel collars would work? Are we taslking inductive sensing or containment? The ED PMH has 90degree turns! So I could use straight pieces with copper windings and the steel collars / pipe slipped over all that.

@all,
This deals with overconduction and it dawned on me to use sensefets to not only conduct for drive but to read the sense line and use that for limiting. It then dawned on me that the thumping in SMs units are the on then off condition using bias control.

I used the sensefet technology back in '93 when enhancing the Otto Bock hand for amputees. There was no variable speed or variable grip so the units acted robotic instead of smooth life like motion. I used a Motorola H-bridge motor controller with current sensing. It is intended for industrial driving. I stuck it on a 5v motor. The operation was sweet. The operator could pick up raw eggs, grapes, potato chips. This had not been done before. All done on a kitchen table...
Well this technology worked before so I think I will apply it again.
http://www.datasheet4u.com/html/M/T/P/MTP10N10M_MotorolaSemiconductor.pdf.html      Just grab the datasheet.

With the erractic operation I have in this unit under the right bias control I bet I can get it functioning better. Gaps in the waveform represent power loss.
But I should add... It looked like the current was coming from the battery. The power expression and extraction is another step.
