Rosemary Ainslie Circuit Demonstration, June 1 2013

The secret is in Body Language.

Become proficient at both "speaking"
and reading body language.

Regarding Inductors.  That may indeed
be the key.

@.99, PicoWatt: Can I ask you to try something in your sims and builds and theoretical analyses, please?

Simply move the Current channel's probe to the other side of the "shunt". Not the common ground point where the probe reference is connected, but rather immediately next to the resistor itself, just on the other side from where it is normally connected. This point is "naively" at the same potential as the common ground so one would "guess" that this simply shorts the probe.... but that would be neglecting to consider the inductance of the connecting wires between the "shunt" and the common ground reference point -- and also neglecting the ability of the probe to pick up the oscillations by RF pickup alone.

Now.... do you have any more difficulty producing the Figure 3 scopeshot with a fully functioning Q1, wired as shown in the schematic, and carrying its full current on to the load?

Sea Monkey is not Ainslie, I am reasonably sure of that. She's tried personal sock puppets before and they are completely obvious. Sea Monkey is an individual all right, but with what agenda? Certainly it isn't to have the Truth be known about Ainslie and her claims.

TK,

I see where you are going with this, and it is a possibility.  Particularly if the Q2 body diodes clamp closer to the levels I estimated.  However, if the the Q2 body diodes clamp closer to what .99's sim predicted, than an issue regarding Q1 or its connections remains more likely.

As well, the oscillation amplitude on the current trace is greater in FIG3 than in FIG5 and one would think it would be less on the battery side of the CSR.

Your "probe on the wrong side" theory might explain the very small amount of current that appears to be flowing during the Q1 on time in FIG6.

Of course, if the probe were on the battery side of the CSR, all data from captures made that way are pretty much meaningless and not as per the schematic.

Possibly you could find .99's video captures he used to decipher the "real" schematic from the March demo and see if the probe position is visible.


If .99 is going to be watching the demo, hopefully he will let us know how it went.  Possibly a video of the demo will be posted for those of us who will not be around on Saturday AM to watch it live.

Yes, it is somewhat less on the battery side of the CVR but the oscillation amplitude is very dependent on probe position, as it is a combination of actual sensed voltage and also RF pickup by the probe.

Yes, of course, but very importantly it _does_ allow the Q1 to be turned fully on and conduct power to the load normally, while not showing any current in the CVR.
It still would invalidate the data, the conclusions and the claims, of course, and would require either a conscious cheat or... .perhaps just a sloppy hookup, with the probe's spring clip coming off the actual tip, for example. Yes... a completely disconnected probe tip can also produce a similar set of traces, due to the RF pickup of the oscillations!

Did you notice? In my last two videos I don't use a probe for the Gate signal at all, I have it T-connected directly from the FG to the scope's input with a BNC patch cable.... but the oscillations show up on the Gate trace anyway.

Possibly you could find .99's video captures he used to decipher the "real" schematic from the March demo and see if the probe position is visible.

As far as I am aware, .99's analysis came directly from the video of the March 2011 demo (which Ainslie claimed she did not post).
I don't think that there are any scopeshots resembling Figure 3 included, and the probe is apparently on the correct side of the "shunt" for that video.

Who knows? I still don't think she's even going to manage to show anything at all, in spite of her announcement earlier today. I do hope somebody records it IF it actually happens, though.
