@.99:

Challenge her to operate without heatsinks, if she believes that her mosfets don't dissipate plenty of power in their Rdss. She won't do it.

Let her remove the heatsink from Q1 and then "bring water to boil 800 mL" with her apparatus. She won't do it.

Challenge her to build a tight build on a PC board and then demonstrate oscillations. She won't do it. Challenge her to just about anything that will test her absurd and ignorant claims .... and she won't do it, because she can't even operate her own equipment, apparently. And when someone else does it for her, she insults, denigrates, and never cites their work when she finds a new set of innocent marks to try to impress.

TK:

Unfortunately Rosemary is locked into a never-ending spin zone with respect to you and your excellent clips and she will never concede anything.

With Poynt she is in "play nice" mode right now.  Assuming that over this coming week that Poynt has the time to build the circuit and test it, then Rosie Posie is going to get blown out of the water.  Poynt has access to that dream four-channel DSO and there is just no chance.

So I suppose that we won't be surprised when Rosie reenters the spin zone with respect to Poynt.  What else can there be?

You just can't get no satisfaction.

@TinMan:
Sure, why not. Your scope shot proves that you can at least manage to make and post your own scopeshots, perform your own demonstrations, answer questions when they are put to you, and provide evidence that you are doing as you say. That puts you _way ahead_ of Ainslie and all her ilk. I'll bet you haven't written a single letter demanding that a busy "academic" pay attention to your reams of word-salad "thesis" either, have you.

From working with you in the past I know that you are careful to avoid making claims you can't back up with demonstrations, and that you are happy to admit when you don't know something and to take advice from those who might be a page or two ahead of you in the book. Personally, I find your explorations a lot more interesting than Ainslie's tired old "zipon" fantasies which explain nothing and predict nothing, and your experimental work is accomplished with a lot more panache and direction than hers is, and should be seen as an example for those who follow. I don't always agree with your conclusions nor you with mine but we manage to discuss matters productively for both of us, and I've had fun with your circuits that I've tested.

Nice that you got hold of a 2-channel scope, and are willing to share data from it. Cheers.... and I hope it has finally cooled off a bit for you, we are already into the 35 degree days here with 40 to come next month.

Thanks TK.
Yes finaly saved enough to get the new scope,and also got myself a nice Atten 20 MHz FG along with an Atten bench top power supply. Still trying to work out a few thing's with the scope,like the math function-but i have Poynt helping me out with that one as much as he can. Im still in junior grade with electronic's,but learning fast. And it is nice to be able to see what is going on in a couple of different location's at a time in a circuit with the 2 channel scope.

Now as far as Ainslie go's,she seems to have you preaty wound up. Maybe this is her intention?-to keep you from doing what you do best(experiment), and waste your time on her bag of lies. If it's any help,i would be more than happy to put the circuit in question together
,and post my result's here. Just throw me the circuit,and i will give it a shot.

Cheers

P.S-the weather is now opposite to what it was. Now it's ruddy cold,but i have my new lab set up in the house,so the fire keeps me warm lol.

tinman,

I'm beginning my build this weekend, and will be testing/demonstrating various things on the circuit. It would be nice if you could sort out that math measurement problem, otherwise power measurements are relegated to spreadsheet crunching. It works but is a bit cumbersome.

Join us, it'll be fun.

Yes, great fun.

.99.... I hope you realize that Ainslie still doesn't understand that a mosfet can function in a linear conductance mode. She still believes that it is either ON with zero resistance or OFF with infinite resistance, and cannot fathom that a gate signal fluctuating around 4 volts could cause a mosfet to conduct partially, enough to sustain oscillations and pass a small amount of current to a load.

Until you can make her understand linear operation of mosfets and the significance of the changing Rdss when a partial gate charge is delivered, she will continue to believe that there are no current paths during oscillations and she will continue to fail to understand the power dissipation in the mosfet's series resistance.

How does she intend to test her mosfets for proper functioning before and after she reproduces the Figure 3 scopeshot? I'm the only person who has ever shown, in this Ainslie context, a simple and fast and easy way to confirm that a mosfet isn't blown, shorted or open, and still works in the linear region to a changing gate charge. How will she do it? How do you recommend that she do it?
