Testing the TK Tar Baby

I've attempted to register at RA's forum to respond to some of the very obvious points directly. This involves a (perhaps manual) approval step. We'll see.

The oscillation frequency at 1.3 MHz may enable the flow of 4 amps through the gate leg of Q2 to the negative rail of the battery supply.  But IF it was passing this current then the voltage would needs must move both above and below zero to show evidence of this.  It does not.  It remains below zero and oscillates around this value at a maximum of 1 volt peak to peak.

Apparently she has yet to learn how to read her own schematic.

Looking at her schematic, the gate of Q2 is connected directly to the probed end of the CSR.  Therefore, the voltage indicated by the CSR trace is also the voltage at the gate of Q2.  The CSR voltage does indeed oscillate above and below ground, therefore, so does the gate of Q2.

Again, the gate of Q2 is connected to the CSR, therefore, the voltage at the gate of Q2 is essentially the same as the indicated CSR voltage (ignoring the effects of lead inductance between the gate of Q2 and the CSR).


Teaching her electronics is like trying to help her put together a 500 piece jig saw puzzle.  A single piece of the puzzle is explained to her and she is told where it goes.  She argues for months about that single puzzle piece but, in the end, she reluctantly places the piece where it belongs on the board.  Another puzzle piece is explained to her, and again, after much argument, that piece is placed on the board.  After a dozen pieces or so are placed on the board in this manner, she starts going back and removing puzzle pieces from the board and throwing them back in the box, apparently because she believes she knows better.  In the end, she will never get to see the "big picture".

Inductive reactance was explained to her a long time ago, yet she recently denied its existence.  The fact that the voltage at the gate of Q2 is essentially the same as the observed CSR voltage was also explained to her months ago, yet even now she does not see how they are connected.  I doubt she actually understands how Q2 is turned on when a negative voltage is applied to its source terminal, though that too was explained over and over. 

Apparently, she continues to throw puzzle pieces back in the box.

She will never see the "big picture"...

I see that went well.  An insult and deletion in very short order!

In fact posts were constantly deleted under my feet.

I have now been banned for being "disruptive"


The sum total of my posts involved:

1) Asking what make and model Greg's batteries were

2) Pointing out that 0.4v is strong evidence of a significant decrease in capacity

3) Asserting that accepting that this is the case doesn't reflect badly on @gmeast.


At no point in my posting was I insulting or used profanity of any kind, with the exception that I stated I did not want to engage in smalltalk or to spend my time correcting RA's misconceptions.

I would recommend Evernote and it's browser plugin as a fine way of recording the state of a web-page before it is altered for whatever reason.

I am also apparently banned by IP address from viewing.
