Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

[Magluvin]

I replaced the circuit on the previous page with the correct diode polarity.

I was doing it at lunch and the circuit looked funky from trying different diode positions that worked, so I redrew to make it cleaner and messed up on that diode.

poynt did not "measure" the green voltage directly at the battery,
what I drew up to do earlier in response to his last postings,
so the battery voltage this way measured is pretty much useless.

We just want to see, if the direct battery voltage rises during the negative current spike.

It also depends all, in what working point the circuit is running,
so the gate voltage is missing...
If the gate voltage is set wrong, it could be underunity.

So poynt, please post the simulation file, so we can check it,
what values you did choose.
Many thanks.

Yes.
that is right.
These new digital scope are so powerful of features you really need to study all their
features.

As all the teacher always say: RTFM.

Read the Fxcking manual ! lol...

Takes a bit of time and testing to get used to it.

Rose, we really need 3 or 4 cycles on the scopeshot from both tests,
so we can really see the exact voltage on the shunt.

As test 1 shows overunity already with the burst envelope and also
with the mean value display, I am not sure what test 2 will
show, when you zoom into the burst to show the single waveforms...

P.S: Best thing would be to just put a variable DC power supply
to the gate of the MOSFETs and have the MOSFETs oscillate all the time,
then you don´t need a complicated triggering for the scope...

So Rose, please try this, as it is very easy.
just instead of the function generator just get a power supply
and feed in a negative DC voltage to the Gates.

Regards, Stefan.

Stefan and all:

If I understand it correctly, I think that Rosemary's benefactors and sponsors who provided the oscilloscopes have required her to return them now, and I think she has said (she can certainly correct me if this is wrong) that there will be no more bench experiments or new data captures upcoming from her team at any time soon.  So it seems we have all the test data we will likely get from Rosemary for the forseeable future.

Hey Penno

Ive seen all this guys vids. I was impressed also.

I have looked at this one and a few others again and again. This one, now that I look at it with details in mind, I dont like the way he thinks he is getting 3 different wires to connect, all together, and then all 3 be disconnected, 3 all at the same time, by hand. Consider the time frame which he gives for switch closure in the drawing, 1 us  even 10 would be a magical feat of enormous proportions when done by hand. 3 connections made and broken all in less than 1 microseconds.

I think that, being that he would have to do the connect/disconnect a couple times to show the charge made, is because of the issue I claim above.  I believe he is getting high voltage into the cap. I think he had a charge instilled into the cap via the charged inductor, but a switch and diode would have done well also.

But we dont know the value of the cap.  We dont know how much power was drawn from the batt, all we know is what we can see and hear with missing details that might confirm things. That cap is huge, but maybe a .5uf at some tremendous voltage rating.

  He did a vid showing a small cap the size of 15 quarters stacked, and producing multiple full charges into a much larger looking cap by just tapping the connections from the small cap to the large, but most of the small caps charge remained.
Well hmmm,  That lil cap could be 10000uf, and that BIG cap could be .5uf .   That would explain it ehh?  ;]   Trix 

If the caps were the same, I would still be drooling and tapping caps to this day looking for the effect, if I didnt ever figure that it was a trick.

He has one vid that still impresses me, but I havnt found a glitch yet

But yeah, to an untrained eye, those vids shock and impress.

And Im not claiming he was trixxin anyone for sure, he just may not have understood some things and didnt recognize issues I see. Dunno. Wasnt there.  ;]  Just my opinion. Educated opinion. =]

hey penn0

lol  im tired lately.  I have to rest before I post any more.
When I linked to the vid, I had ff to see which one it was and forgot he had shown the value of the cap.  Wasnt tinking properly for a couple days. Gota get some sleep tonight.

I referenced other of his vids also but now I have to go back and see which ones I had actual issues also and post it more clearly.  ;]

Im beat.
