another small breakthrough on our NERD technology.

Here's that circuit again.  Look closely.  The Source of Q2 IS NOT CONNECTED to the NEGATIVE BATTERY VOLTAGE  or, a I call it,  to the SOURCE RAIL of the battery.

Rosemary,

First of all, slow down, calm down and READ WHAT I SAID. I DID NOT say the scope was measuring incorrectly, I have said this a dozen times, every time in fact that you MISINTERPRET what I say in this regard.

I said that the scope probes are placed at the wrong locations to make the measurement, and THAT is the reason the measurements are not valid.

Rosemary,

POYNTY - Trust me I'm calm.  You have advised us that a CORRECT measurement is only possible if the probes of the oscilloscope are placed directly across the battery terminals.  WE HAVE DONE THIS.  REPEATEDLY.  NO CONNECTING WIRES OTHER THAN THE CIRCUIT WIRES.  We've applied ENTIRELY different circuits switched by 555's - and still used our batteries - with LESS THAN 16 inches of wire in those ENTIRE CIRCUITS including the connection to the battery.  WE ALWAYS GET THAT VOLTAGE SWING.  I keep telling you this.  Somehow you keep ignoring it.  Not only did we do this test - but we did it publicly - HERE ON THE FORUM.  I downloaded the data.  I cannot get those scope probes more directly onto the battery - a SINGLE BATTERY - short of soldering them directly to the terminal.  THEY ARE NOT THE RESULT OF OUR PROBES BEING IN THE WRONG POSITION

You need to look deeper Poynty.  I'm trying to show you where to look.

Kindest as ever,

NOW.  LOOK AT THAT CIRCUIT DIAGRAM.  The difference between Q1 and Q2 is this.  Q1 has it's source (Q1S) - soldered to the common battery source rail - or as you like to call it - to the negative terminal of the battery.  Q2 conversely - HAS NO CONNECTION TO THAT common battery source rail - or, as you put, to the negative terminal of the battery.

Again.  I thought - through those endless questions that you had FOUND a connection.  In truth you hadn't seen its lack.  This is what I'm trying to point you to.  Check it out.

Kindest as ever

changed 'he' to 'you'.

SO.  Here's the thing.  IF I apply a positive signal at the Gate of Q1 then the current can flow from the Q1 Drain through the Q1 Gate to the Q1 source.  AND BACK TO THE NEGATIVE TERMINAL OF THE BATTERY.  Well and good.

Now I apply the positive signal to Q2.  It can conduct from the Q2 Drain through the Q2 Gate -  AND THEN?  To the Q2 source - TO WHERE?  THE SIGNAL GENERATOR?  Because that's it's ONLY connection.  It can't go BACK TO THE NEGATIVE TERMINAL OF THE BATTERY.

Do you see this yet?  The CIRCUIT IS OPEN.  It is not connected by Q2 - notwithstanding the positive signal at the gate of Q2.  It can go nowhere.  The source leg of Q2 OR Q2S FLOATS.

And more emphasis.  Sorry guys.  I think I managed my point - finally.
