Testing the TK Tar Baby

[TinselKoala]

Thank you for stating that so clearly, PW.

I hope that my earlier comment about the gate of Q2 therefore being _relatively_ positive wrt the negative voltage applied to the source is also clear in this context.

It's easy to see this when the floating external battery supply is used: the positive of that battery goes to the gates of Q2 -- which is always indeed at circuit ground -- and the negative goes to the sources. But because of the way the circuit is wired, this external battery (or substitute like FG or 555 timer) is in series with the main battery whenever and to whatever extent the Q2 mosfets are conducting.

However, as usual, Ainslie confounds several distinct cases here. Recall that we are talking about the DC case when the FG or the external supply is _strictly_ negative at the Q2 sources. But in the Ainslie experiments she is sometimes using a FG set to produce a pulse _and also_ she is offsetting that pulse with the offset control. This means that sometimes she is actually giving her circuit a bipolar pulse with the FG even when she doesn't realize it or see it in the _gate trace_ of the scopeshots (it shows in the current trace of course.)

TK,

It is clear that there is a a lot that is not "realized".

Some people need to know more just to know what they don't know.

Is the Cav still running well?

Hi Rosemary,

I think it is better to make some new experiment, than to rant here all the time.

Just do the experiments and prove TK wrong if you can do this with your setup...

And show it in videos as he is showing it.

I got again some complains of some users that you only rant here and don´t do the required
experiments.

But Rosemary completely ignores this and continues with her personal attacks, veiled threats and self-contradictions, while continuing to refuse to address or correct the three latest major errors that I have been asking her about. And she gives no evidence or support for the things she claims.

TK, Picowatt, MileHigh, FTC are CONSTANTLY referring to ME.  With every reference they entitle me to defend whatever is erroneous in that reference.  Else I would have no voice which is what TK is hoping to manage.  And we all know why.

Kindest as ever
Rosemary

Heh... well said, and that certainly applies to me as well; I've certainly learned a lot over the past couple of months that I didn't know I didn't know. Or maybe I'd forgot that I didn't know, or didn't know I'd forgot. Or something.

And probably didn't really need to know, or remember, either, but there it is.

Yes, the car is still running fine, scary cool, when I can afford to put gas in it. I didn't make the intended trip today though; maybe tomorrow. I want to get some solid mean power results using IRF830as and I'm too lazy to do it manually again.

Voltages are relative:
