About the Ainslie circuit:
When Rosie miswired the extra MOSFETs she modified the circuit.
Let's start with the original circuit.
The current starts at the battery positive terminal and flows through the heating element and then the Q1 MOSFET and then through the shunt resistor and then into the battery negative terminal.
Let's call the end of the loop, the Q1 MOSFET to shunt resistor to the battery negative terminal "Path A."
Now let's look at the simplified version of the circuit that adds the miswired Q2.
With the Q2 addition, there is now a second path that the current can take.
The second path is as follows: <battery positive terminal to heating element> then the current flows through the Q2 MOSFET then into the function generator and then into the battery negative terminal.
Let's call this a second end of the loop, "Path B."
So here is what happened:
Rosie worked with the original circuit and the end of the current loop was always following Path A.
She then added Q2 and played with the offset of the function generator.
What happened as a result of this is that Q1 was shut off permanently, so Path A was now closed to the flow of current.
What also happened was that Q2 switched on, and the current flow started taking Path B, bypassing the shunt resistor.
Unfortunately, Rosie was not aware that this happened. For months she was in total ignorance of this fact and made regular postings stating that she had a circuit that was "COP infinity."
It's as simple as that. The current flow jumped from Path A to Path B and Rosie was not aware of this and claimed COP infinity.
Poynt asked Rosie to explain how a MOSFET works and she was unable to do this. This supports the notion that for months Rosie was blissfully unaware.
As luck would have it, the circuit also started to oscillate, and Rosie saw the oscillation waveform as being an indication of the current flow but this was never the case, the current was taking Path B the whole time.
And now, we are in a struggle to get Rosie and presumably many others to see this. I tried above to lay it out in black and white for you, I hope it gets through to some of you.
The two MOSFETS in the circuit ended up acting like a double-pole-single-throw toggle switch for the current flow. Rosie was simply not aware of this fact.
This means that there can't be any "EXPERTS" because if I recall the experts were supposed to be in on the subterfuge about the miswired MOSFET. Anybody with basic electronics knowledge would be able to figure out this MOSFET switching business in one day, and some in five minutes.
Since Rosie is sticking to her story and won't budge, we are left with a "Who's Afraid of Virgina Wolf" psychodrama and it's just ridiculous.
I think a lot of the lurkers on the forums should speak up. You want a place where you encourage each other to do better. Look at how ridiculously Rosie has refused for months and months to do alternative tests and dismisses them as irrelevant when at the same times it's staring everybody in the face that she knows nothing about electronics. The schematics fiasco is also unacceptable. This is a form of intellectual stagnation disguised as research.
So that's another recap of the story as far as I am concerned.
Yikes!
