Claimed OU circuit of Rosemary Ainslie

[poynt99]

you get that $10 fet yet? or are you a hypocrite?

@poynt99
what fet did you use? the same as tk? or the right one?

I used the IRFPG50 as noted on the diagram. You may not have noticed, but this circuit was modeled and simulated. Mainly I wanted to confirm the duty cycle, which I did.

Most component models are pretty good if one knows how to use them, but I didn't expect the MOSFET to oscillate. I wouldn't be surprised mind you if it did, as PSpice has impressed me with it's accuracy many times over the years I have been using it.

The IRFPG50 has a relatively high gain, but also  a high input capacitance. Probably why it likes to oscillate in the low 100's of kHz. I tried 1000 Ohms in the Gate and no oscillation. Again, the model may not be 100% correct, but I will look into using perhaps the small signal model instead of the large signal one. This might do it.

re: your first paragraph. ie:more tk BS

look, $4! gasp! and if you would learn to use the web for something other than being a tick, you might be able to find a single IRFPG50 fet for half of what you claim they cost.

re: your second paragraph. it was a rhetorical question, more of another poke at you to get the right one. obviously...

edit: i'm curious though, and feel free to jump to the conclusion that ainslie is my new hero. how much did you spend on those "brand new" 20ah batteries?

Well, clearly you have the ability to order your own parts and build your own circuit, since you can use a web catalog. Oh, wait--using the catalog only requires a single finger for typing. Actually building something requires opposable thumbs.

If you want to buy that from ebay and send it to me, I'll deduct the cost from the bill I send you for the consulting work.

And the batteries cost "somebody" seventy-six dollars each. But I just had to walk around the building to get them.

Now, from your elevated pulpit, can you read me the gospel chapter on how the choice of any particular N-channel mosfet would make a likety-split of difference in the duty cycle issue? And why do you care so much anyway? Why don't you go attack her, there are a LOT more holes in her story than you will ever find in mine.
Zipons! Hah!

Hey, .99, could you stick a 2SK1548 in the model and see if you see any real difference? I'd also like to know if adding a little external capacitance to the 2sk is predicted to make any difference.

Of course, "Wilby won't be" happy until I find the exact same circuit board material that Ainslie used and run the experiment in the southern hemisphere. Since those things clearly make a huge difference--after all, hers works and mine doesn't. So clearly the fault must be in my construction or location.

No, wait...we don't know if hers works or not, since we don't have any real idea WHAT THE RIGHT CIRCUIT IS, and she won't tell us. All we really know is that nobody anywhere, working from the information she provides, has gotten any overunity performance...no matter what MOSFET or batteries they used.

I've been using a 200 K pot to vary the gate; the mosfet behaves interestingly only when the gate input resistance is very very low. Like at zero ohms.  Otherwise the pot works just like a gain control. Duh. Using the 100 ohm pot here is incomprehensible to me as it has almost no effect on the circuit. This is another discrepancy in the Quantum circuit that needs explanation.

Something else "Very Good' is happening this week.[in regard to this circuit]


S.Roksund

I am a Novice member in this forum, but a retired electronic engineer with some 35 years of experience. I take the chance that my posting is a little bit beside what is discussed in this tread.

In the last one and a half year or so I have done research on capturing energy from the inductive back spike from transformers. I use my own kind of circuit and use a microcomputer to control the switches. Experimentally I have several times â€" and with different duty cycles - obtained  2 - 5  times electrical energy output relative to the input.

I have read a lot in this forum and other forums - of similar circuits to the Rosemary Ainslies, and I am worried of the fact that she and Peter Kevin ASHBY has obtained a patent on a circuit which seem to operate in  similar - or quite similar ways, that many  other publizised circuits do. In my oppinion it should not be possible to get a patent on a system or circuit that have been discussed openly for such a long time.

It is good if no patent has been issued.
I will post my electronic schema and a component list - as
well as the measurement methods I have used, here in this forum.
My intention is  that someone (hopefully) will make a replicate and test.
When I get the circuit and measurements confirmed, I will start making
units that can be tested in practice - before I start the production.
If all fails, - well it has been exciting all the way, and I have learnt a lot.
I am leaving to celebrate my mother (98), so no posting until next week.
