And just to put another point on it: it is EASY to assure that you have "no discharge from the battery during Q1 ON times"... simply have no Q1 ON times, by using a DC bias source or a FG that can produce a DC output level.

But if you supply a +4 volt Gate signal, you WILL have significant Q1 current, and if you supply +12 volts as the Figure 3 shows you will have fully turned on the Q1. 

Are you paying attention, Ainslie? Donny? Whenever you refer to Figure 3 and attempt to use it to support ANY claims.... I will remind you of the June 29 demonstration which showed that you absolutely cannot make Figure 3 honestly, with people watching you.

Remember THIS, Ainslie?

http://www.youtube.com/watch?v=w4bxAobjN98

This is the video segment, made before S.Weir joined the conversation, when you can be heard speculating that S.Weir is TK, trying to sabotage your demonstration. (4:30 on) Unfortunately for you, Ainslie and Martin.... you showed yourselves perfectly capable of sabotaging your demonstration all on your own. I don't need to sabotage anything.... YOU simply need to show the truth. And you did: your Figure 3 scopeshot is FRAUDULENT, manufactured data, and you cannot reproduce it honestly when people are watching you.

Well... I must say that I am very impressed. If Ainslie actually understands what she wrote, and isn't merely parroting something Donny or Steve told her... then she ALMOST gets it with this latest post. ALMOST.

Now if she would only watch and understand the Negative Bias videos that I have posted, with their schematics, she might be able to understand the situation properly.

The battery is never "disconnected" ! It is acting in series with the FG during the negative portion of the FG's output which is producing the Q2 oscillations! And the current through the FG is generally in the range of 100 to 200 mA, and is varied by the negative setting of the FG's offset control. This means that the internal impedance of the FG must dissipate 2 Watts at most. This is not a problem. The problem is in Ainslie's claim that there is 7 Watts of power in the oscillations. There is not; if her load resistor is dissipating 7 watts then some of that is coming from Q1 partially conducting, which it DOES INDEED do at a Vgs of +4, and even a bit under. Q1 current does not pass through the FG's internal impedance.

Just get a nine-volt battery and a potentiometer and hook them up as shown below, and you will be able to have CONSTANT Q2 oscillations for as long as you like, with no FG at all,  and they will be the identical oscillations you get with your FG's negative offset setting. You don't need to turn Q1 on at all.

I DARE YOU TO TRY THIS, Ainslie, and explain what it means. Or get Donny or Steve to tell you what it means. Why do you need a Function Generator AT ALL ? The Q1's role is completely normal and ordinary, isn't it? No magic there, the oscillations are what matter.  RIGHT ? ?

Just be sure to use a 2-Watt potentiometer, like a "type J". Steve will know what that is, even if Donny doesn't.

At what Gate voltage (denoted by VGS) does an IRFPG50 begin to conduct?

Let's put our collective mental energy together to get the current viewing resistors to Rosie on time.  My compliments, that MOSFET gate voltage demo board was very Frankenstein laboratory like.  It would make a good "rack" for torturing little innocent DC motors.

I was thinking of little one-inch-sized motors, something safe.  But look what the Engine yielded:

I'm somewhat disappointed that it appears they will be going with a 1 Ohm 5W rather than the "standard" 0.25 Ohm for the new CSR off the battery. This is insane, as my analysis indicates that with a 72V supply, 20% duty cycle, and full +/- gate drive, that 1 Ohm CSR is going to be dissipating an average of about 20W! Hope they've got a fire extinguisher on hand. LOL.

Also not good practice, is they will be shorting this new CSR when testing with the horrid original CSR array, but leaving it 'in_tact' for the remaining tests.

Poynt:

Those ceramic resistors get a nice internal red glow if I recall.  Like a hot coal, something that could burn a hole in your carpet and cause paper to ignite.  Meanwhile I think I read that Rosie wants to measure the resistance of the function generator by putting her probes across the FG leads, presumably when it's on?  That makes the multimeter very unhappy.

Also, these guys are nicely nuts!

Yes, those guys are nuts.

Imagine their 1 Ohm 5W CSR as this neon tester:

And btw,

If they had chosen instead to use the value I recommended, i.e. the 0.25 Ohm, it would only dissipate about 5W for the same settings.  ::)

I don't understand all this kerfluffle over the silly csrs. She has four perfectly usable non-inductive resistors that she can use. They are rated 1 ohm 25 Watt and are designed to be heatsink mounted easily. Two in parallel at the Batt neg post with a nice copper strap connecting them, and two in parallel at the present position on the board mounted as they are now, would make me perfectly happy. Nothing needed to be bought except for some copper strip or braid.
The "negative power product" will still be there as before, Poynt99's tests will still work as before, everything will be fine.



Here's another little puzzler for you all to consider.

Using the schematic below, the standard one but with the insertion of DC milliammeters as shown. Set the FG for DC output at whatever negative voltage that will give oscillations in Q2 and an indication of 120 mA on the meter mA1. (Or if you can't set DC output, set a short Q1 ON duty cycle and a gate drive of 0 V positive to keep Q1 off, and set whatever negative offset is necessary to make the oscillations and give the 120 mA1 reading.) For me with Little Bryan (one Q2) this is about -8.3 volts DC unloaded, of course clipped to about -4 volts when hooked to the circuit.

Now... What does mA2 read?

Next.... without changing anything on the FG... open the Switch. What do the ammeters mA1 and mA2 read?

Next.... without changing anything,  disconnect only the Drain of Q1. What do the ammeters read?

Compare, contrast, discuss.

They don't want to disturb the build of the apparatus, that's why they are ordering extra CSRs rather than robbing from the array. I am OK with that.

Last thing we want is to have Rose crying that we made her butcher her precious apparatus and now the mojo is gone.

Regarding your quiz, perhaps you picked that idea up from my video #11 (http://www.youtube.com/watch?v=s1ytR1uu8TM)? Anyway, the M2 meter should read very much the same regardless if the SW is open or closed. And M2 should read about 1/2 when you disconnect the Q1-D (and SW is open).

Did I win something?

I know, I  know, I don't want them to disturb their apparatus  needlessly either. It's just too bad they can't seem to follow directions or understand simple explanations. Or Ohm's Law, apparently.

Have we gotten a clear statement of Ainslie's claims, what she -- or rather Donovan Martin -- will be demonstrating, and what data from the demonstration will either support or fail to support her claims? Should we not have such a document, before the demonstration proceeds?

I remember a few days ago she was claiming that the power dissipated at the load will be at least an order of magnitude greater than the total power delivered by the battery and Function Generator.
In her recent posts she seems to be backing down from this position. Did someone finally explain to her what "an order of magnitude" really means?

I really want to see her dissipate 7 watts at the load while only drawing  250 mA from the power supplies.
(7 Watts == I2R, so solving for I, we have I = sqrt(7/R) = sqrt(0.63) == 0.79 A required by "conventional" electronics, so an order of magnitude less from the power source would be 0.7 Watts == I2R, so I = sqrt(0.7/11.11) = sqrt(0.063) == about 250 mA.
(But what is the actual impedance of the Ainslie load at the oscillation frequency of 1.5-2 MHz?)

And where are the scopeshots that SWeir had them make at the previous demonstration? Are these considered irrelevant now that Ainslie has publicly admitted that she was utterly and completely WRONG about her claims referring to that Figure 3 scopeshot? They are not irrelevant to me: the very fact that she has withheld them, instead of publishing them immediately, indicates her further mendacity. We can't discuss data that the claimant refuses to publish! But at least we can see that her former excuse about not wanting to bother Donny... is bogus, since they have been in constant and repeated communication for the past two weeks.

I am ROLLING on the floor laughing. Ainslie is now claiming even more strongly that the battery is completely disconnected during the Q2 oscillations.

Quote
Effectively the circuit exploits that voltage imbalance albeit that it does not NEED the current discharge from that battery supply source.  INDEED.  We argue that it cannot discharge current.  IT'S DISCONNECTED.

This is so easy to disprove it is laughable. Simply establish a 100 percent Q2 oscillation with no Q1 on time at all, or use Ainslie's "Figure 3" fantasy but assure that there is in fact NO current showing on the scope during Q1 Gate HI times by using less than 3.6 volts (4 volts is too much, it does turn on Q1 partially). Then stand back and let the device run.

DO THE BATTERIES RUN DOWN? Of course they do. But according to Ainslie, they are DISCONNECTED. So how can they possibly run down?

In fact it is not only completely deluded of her to make this claim, it is an insult to the intelligence of anyone reading her nonsense. If the battery is completely disconnected as she pretends.... then why does the behaviour of the circuit change when you unhook the cable to the Positive battery terminal? It's already DISCONNECTED according to Ainslie, so how can disconnecting it again, or more, possibly have any effect on anything?


On anything except her silly "thesis" and claims, of course.

It will all be resolved this weekend (hopefully), assuming the testing actually goes ahead, and it doesn't get botched in any way.
