Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

I think I'm up and running and ready to go.  The only problem - right now - appears to be with my back up computer.  I'll need to use yet another. And I still get kicked out of the system here when I reference a second internet link.  Can't do the two simultaneously. 

I also need to advise you all that this little 'repartee' with Poynty Point is going nowhere.  I'm afraid I'll not be answering any more of his posts.  I'll try and give a summation if I'm able to stay logged in here.

I am certain many here would not agree. It is most unfortunate that just as we were about to make some small progress, that your computer somehow has become "unusable".

Ok everyone.  It seems that this is going nowhere.

We could make some real progress if you'd kindly answer some of the important questions put forward.

Groundloop your positioning of the ground from the functions generator is how we configured it at the demo.  This was simply because we ran out of space at link in series with the shunt.  It already had 2 probes there to accommodate the two oscilloscopes we were using.  But it can be put in either position.  As mentioned it doesn't make a material difference to the results.

In terms of the schematic, ground is ground. The question was clear, it deserves a clear response.

I had a long conversation with one of the guys last night.  Apparently we're positioning the transistors as if the second Q2 is being used as a P FET.  But that is NOT to say it can be replaced with a P FET.  It may be possible.  I just don't know.  What I do know is that it's being triggered with a negative current and that the flow is then returning to the battery.

It is encouraging to see that my posts are apparently of some benefit to your team. They are "getting" the hints I've been offering in the schematics. The last "simplification" was intended to point out the use of Q2 as a pseudo-P-channel.

Poynt's schematic shows the Q2 being linked directly to the shared ground.

Could you please explain this?

This is wrong.  Also. the Source and Gate of Q2 needs to be transposed.

What is wrong exactly? The S and G of Q2 are connected as per the demonstration circuit, and as per GL's rendition of the same circuit.

The diode at the drain remains the same.  I'll post the revised schematic but PLEASE NOTE.  The diode at the drain does not change.  Only the diode at the gate.  I can't even give you my own 'scribble' here because the second computer is pretty well 'fried' now and that holds my photobucket and sundry software. 

You are using unconventional terminology here. Also: There is only ONE diode in the MOSFET Rose, and that is positioned from the MOSFET S-D pins, anode to cathode.

Hi Grounloop.  Yes.  It's the one used in our test video.  But I'm saying that on the understanding that the source and gate have been transposed.  Which also means that the drain has it's bias in the opposite direction to Q2.  I would prefer it if you could just try and make sense of the attached circuit - because that's what's required and this is the only schematic that I can read.  Sorry guys.  But that's the best I can do.

Kindest regards Groundloop.  I wish I could just leave all circuit commentary to you.  I have not got the required skills and - with or without respect - I don't trust Poynt's representations of anything at all.

Regards,
Rosemary

Rose,

The circuit as you have depicted it will not work. Not only is it incomplete, but you have flipped the fixed DC source so that it is providing a +5VDC voltage at the Source of Q2.

May I ask who advised you to alter this circuit in such a way?

I doubt very much that anyone will be able to make sense of your strange and erroneous edits to my diagram Rose. You should have left it as is, because that IS precisely what your circuit is that was used for the demonstration.

For the record, I do not endorse any of the edits that Rose has erroneously made to any drawing I originated.

For the correct circuit connections of the apparatus used in the video demonstration, please refer to the "video_as-built_circuit_connections.png" circuit above, or any of several other drawings I have posted in this thread.

Let's finally shed all doubt as to what the circuit connections are/were for the apparatus used in video demonstration Rose and her team gave. This is also presumably the same apparatus that has been used to acquire all the scope shots and "data" Rose has been posting over the last couple of months.

Compare this underside view of the perf-board connections they used to build the apparatus, to the circuit diagrams I have posted, in particular to the one attached here.

Are there any significant discrepancies between the two?

Note: M1 in my diagram = Q1, and M2 = Q2-Q5. The "CSR" in my diagram is lumped into one CSR, as all 4 resistors are in parallel.
