Testing the TK Tar Baby

[TinselKoala]

Once again, Rosemary seems to have trouble reading what's written. Compare her rant to what I actually posted. The resistors are as I described, I never mentioned the unconnected fifth resistor, I never said anything about a 10 ohm resistor at all.... and so on and so forth. She is doing what I specifically required her not to do -- distorting my data, not representing it correctly, and flat-out lying about it --  and hence I will persist in asking that she be blocked from posting here.

Based as it is on the assumption that we're using 4 x 10 Ohm resistors.  Golly.

Do you see this lie? NOWHERE did I ever say or "assume" that they are using 10 ohm resistors.




Now... moving forward without the noise:

There is another glaring discrepancy in the first paper. Several places in the text describe tests using a negative-going gate drive pulse. Yet EVERY scope shot in that paper shows the gate drive pulse going positive. This figure particularly: the text describes the negative going gate drive pulse but the scope shot clearly shows a positive pulse of around +12 volts. And yet... no current is shown in the current viewing resistor trace.
ETA: the gate drive pulse is more correctly described as a "negative going pulse".... but it has a +12 volt offset of its baseline, so when the FG signal is "off" it is actually sending a +12 volt signal to the circuit, as if it were a positive pulse of short duty cycle.  This should turn the Q1 mosfet on and cause it to conduct measureable current on the shunt signal. But it does not.... indicating, again, that this transistor may be defective in this shot.

So TK.  On the whole I'm inclined to think that your 'claimed' replication falls on it's knees at every point.  I think you need to start again.  And I'd recommend that you do this with some adequate measuring instruments.  As fine and as antique as are your own - they do not meet the required measuring standards.  And then you need to measure the appropriate 'thing'.  So far we've seen no detailed analysis of any current flow at all.  Perhaps you misunderstood our claim.  Or perhaps you deliberately misrepresented our claim.  I'm not sure.  And nor do I much care.  Bottom line is that your arguments are spurious and unsubstantiated.  I would be delighted to see a genuine effort at replicating our claim and then seeing how this effects the draw down efficiency of the battery supply.  That would be an interesting thread - INDEED.

Since you think this is not a replication.... why don't you go post your lies and distortions somewhere else.

TK - if you do not want my input it can only be because you want to comment - free from contradiction or challenge.  In effect the TarBaby thread would then be as relevant as a 'gossip column' - and have no relevance to any facts at all - let alone to science.  Frankly I think that would be a gross insult to the objects of this forum - a gross insult to the integrity of our readers - a gross insult to the intelligence of both our members and our readers - and a gross abuse of impartial and relevant assessment owed to good science practice and protocols.  It would be a gross abuse of the interest owed to the public good - which requires impartiality.  And it would be a gross abuse of the 'real truth' which is MileHigh's measure of excellence - albeit that it's somewhat tautological.

Therefore I put it to you that my input most certainly IS required.  God knows what our readers would have deduced, thus far, had I not pointed out where you TARBABY circuit is NOT a replication.  Because in defiance of the evidence - or the lack of it - (one or other or both options, as preferred) - you keep insisting that it is. 

As ever,

Changed deviance to defiance - but both terms are appropriate.

Some wirewound ceramic power resistors. All are 1 Ohm.

From the top:

1 Ohm, 10 Watt, as used in Tar Baby and the NERD demo video.

1 Ohm, 5 Watt.

1 Ohm, 1 Watt.

All have similar inductances of 5-7 microHenry.

The ruler is in inches. The holes in the NERD pegboard are 1 inch apart. The holes in TarBaby's circuit board are 0.1 inch apart.

Poynty Point.  If you're there.  PLEASE put TK straight.  I'm now seriously concerned that he's convinced himself that we're NOT using 1 Ohm resistors x 4 - in parallel.  You're well able to show this.  I can't.  I can't even find the appropriate shot.  It's too dark here and it's too late and my eyes are not equal to it.

Kindest regards,
