Testing the TK Tar Baby

She can not only edit and censor, but she has explicitly excluded "some" of us from registering or commenting at all.

Not only that, but her continued posts and links here are also deliberate "Honeytrap" attempts to garner IP addresses and whatever other information can be obtained from your browsers.

Ah, the honeytrap.  But which IP is who, as in just guests?  Does she just wait for the few guests that arrive after posting answer links here, and put them on a list?

TK,

As you can see from a repeat of my earlier post below, I was generous and only used 2000pF per MOSFET as the gate to source capacitance.  This varies with applied voltage a bit, but 2000pF is probably close to or less than the actual amount.

It is not just 4 MOSFET capacitances in parallel, it is all 5.  Draw two caps onto the NERD circuit.  One is a 2000pF cap between Q1's gate and source.  The second cap is an 8000pF cap (4X2000pF) drawn between Q2's gate and source.

If you now look at the NERD schematic with these two caps drawn in, you will see that both caps are in parallel with the FG terminals, allowing AC current to flow directly to the CSR via the MOSFET capacitances, which total 10,000pF in this instance, and possibly as much as 12.5nF or even a bit more).

As I say below, at 1.5MHz, the reactance of 10nF (10,000pF) is approx. 10 ohms.  So this represents a 10 ohm path for AC currents from the Q2 source directly to the CSR.  The harmonics of the oscillation will, of course, see an even lower impedance path.  The second will see 5 ohms, the third 3.3 ohms, etc.

(If 2.8nF per MOSFET is used, these numbers drop to fundamental=7.5ohms, second=3.8ohms, third=2.5 ohms)

When Q2 is biased on, its DC bias current flows ONLY thru the FG, the CSR and to the battery negative.

AC current, when Q2 is oscillating, flows thru BOTH the FG and thru the MOSFET capacitances, with the MOSFET capacitances being the lower impedance path of the two.  Both paths then flow thru the CSR and to the battery negative.

(The above assumes the FG common is actually connected to the CSR as per the paper's schematic and not to the battery negative)

So, as you can see, there is no mystery at all as to how more AC current is able to flow than one would expect if only the Rgen=50R path is considered.  There are two paths for AC.  The FG AND the MOSFET gate to source capacitances.

Once this is accepted, then Coss must as well be considered.  But that can come later.

(And no, this is not a new position, I stated this way back in the locked thread.  But then, as now, it fell on her deaf ears.)

Right....thanks for reminding me that all 5 Ciss capacitances are actually in parallel.  Your numerical analysis is right on, but I doubt particularly that things like Fourier decomposition are within the pale of discussion.

In my little video I simply wanted to illustrate that a capacitance on the order of that in Ainslie's mosfets could indeed pass substantial AC power at the frequency of the Ainslie oscillations. Ciss, but also KISS, you know.

And of course that the FG itself is a substantial source of power.

And also that the capacitor would be a solid block to DC. That could be illustrated better by using the series battery to put a large DC offset on the FG signal, then showing the scope trace with and without the series capacitor. Do you think that a demonstration like that would be of any use, or that it would relate to any of the topics we have recently discussed?

Sure, all visitors IP addresses are always logged anyway, with timestamps, in the server logs, if the sysop is savvy.
And she knows certain things about some of us... or thinks she does anyway. Like I'm in Canada, or maybe Texas. So despite her inability to put two and two together and obtain four, it's possible for her ... with considerable assistance from her ten-year-old neighbor, probably ... to gather a bit more information about those persons who keep hacking her computers and rifling her flash drives for all that incrimin8ing d8a.
But we wouldn't want to make things any easier for her by talking about it. So shhhhh !!


And really, it's not a honeytrap. More like a moldy cheese trap, actually. Still attracts flies, but they don't get any honey, just bad smelling slimy old rotten goat's milk cheese.

TK,

I would not even consider visiting that site without a ten foot or longer pole...

Somethings odd with her always only providing answers via having to go to here site, when they could simply be posted here.

Probably so she can edit them as she pleases later to CHA.  ;]

Her "forum" is more like her personal blog.  She enjoys being able to misrepresent and misqute posters from here and put her spin on it to meet her agenda.

What she probably doesn't realize is that with all her commentary, Doggerel, and nonsense technical discussion aimed at posters here, she is merely instilling curiousity in her readership (however small that is) and likely directing them to seek out ths forum to see what is going on.  So, in the end, any cross readership from there will likely get to choose between her nonsense and the more technically sound discussions here.

I am anxious to see what Chess is working on.  I only hope that her presence over there , her silly Doggerel, her lack of technical skills, and her nonsensical postings do not tarnish the credibility of his efforts by association.
