another small breakthrough on our NERD technology.

Rosemary,

That is exactly what I said.  When the FG output is a negative voltage, Q1 is turned off and Q2 is biased on. 

We seem to be in agreement here!

And of course, conversely, when the FG output is a positive voltage, Q1 is turned on and Q2 is turned off.

PW

But picowatt - with respect.  You argued that with that negative bias at Q1 then energy was being returned to the battery supply via RLoad.  And what I'm asking you is how can this be when the current from the battery supply is enabled at Q2?  Or are you conceding that there is no flow of current during this period?  I'm not sure that you can have it both ways.

Regards,
Rosemary

@PW: Perhaps something like this could help your efforts to explain how to read an oscilloscope to Rosemary.

( If it's not a number in a box, she has difficulty with it, and we know that all numbers in boxes must be correct... else why put them in a box? )

These are of course shots from the video; I haven't bothered to do the same for the shots in the paper because they are clearly garbage: unknown circuit, evidence for blown mosfet(s), etc. The video of course used the common ground point for the FG negative lead, in spite of its two false diagrams, the one shown and the one claimed until .99 straightened it out.

See, PW? She knows more about using oscilloscopes than you do, or will ever learn. Can't you see that there are NUMBERS in BOXES?

Oh... I almost forgot... the Mystery Scopeshot.

Rosemary,

Again, referring to the portion of the cycle when the FG output is a negative voltage, Q1 is turned off.

At the same time, Q2 is biased on and allows about 200 ma. of DC current to flow.
