another small breakthrough on our NERD technology.

[Rosemary Ainslie]

A simple test to prove the battery voltage can not and does not fall to 0.5V.

Take the load resistor out of your circuit and place it DIRECTLY across one (or all) of your batteries. Meanwhile, have a DC voltage meter DIRECTLY across the battery terminals.

NB. The load resistor must be connected DIRECTLY to the battery (or batteries) with no more than 18 inches of heavy wire.

Note what the battery voltage was before connecting the load, and what it is after connecting the load.

Poynt - I am not good at following complex circuitry.  I would prefer it that you simply take our own schematic.  IT IS EXACTLY AS OUR APPARATUS IS SET UP.  Then - if you need to add probes from the scope - if that's what you're proposing - go for it. 

But those switches CANNOT be represented any other way.  They're EXACTLY RIGHT.

Why?  I don't see the point of this.  I assure you I'll not see that oscillation.  And that's what we're discussing.

Actually Poynt.  With respect.  I cannot tell you how much this sort of post irritates me.  WE ALL KNOW that a load directly in series with a battery supply does not induce an oscillation.  But we don't have a load in series with a battery supply.   HOW WOULD THIS CONSTITUTE PROOF OF ANYTHING AT ALL?  I am claiming that the voltmeter DOES NOT READ THE BATTERY VOLTAGE AS THE BATTERY IS DISCONNECTED.  IT IS ONLY READING THE VOLTAGE OR POTENTIAL DIFFERENCE AT THE LOAD.  Chalk and cheese Poynty.  They're just SO different. 

PLEASE THEREFORE DO NOT TRY AND SAY THAT 'I've thereby proved to you that the battery voltage is not able to show 0.5 volts.'  WE KNOW THIS.  You're arguing our own point.  If I can get around to it I'll point you to that part of that post of mine WHERE IVE SAID THIS.  Do you ever read what I write?

HERE IT IS - JUST WRITTEN TODAY.

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,
R

And to make it perfectly clear - here it is again.

I cannot get those scope probes more directly onto the battery - a SINGLE BATTERY - short of soldering them directly to the terminal.

Hopefully now that is clearer.  The probe was positioned directly on the battery positive terminal - the Drain rail.  The ground can't quite reach the negative terminal - but with 2 inches of wiring from the neg to the probe's ground - it gets there. 

Then we did an arrangement with short wires connected 2 batteries in series - and the probes placed directly over both terminals.  I think it was Groundloop or someone who explained how to do this.  Can't you remember?

Yes we are discussing the oscillation of what you are calling the "battery voltage", and I am trying  to take steps in order to formulate my argument. However, you seem determined to sidetrack my efforts in this regard. I can not have a meaningful discussion with you if you insist on doing this.

Where did I say that one should expect the simple circuit I explained, to oscillate? One of YOUR arguments is that the battery voltage falls to 0.5V during certain points of the oscillation, correct? With the simple DC test I explained, you will see that when fully loaded with the load resistor, the battery voltage will remain around the 12V mark, perhaps it may drop a volt or maybe 2 if it is already almost completely discharged. You agreed that the worst case load for the battery is the 11 Ohm load resistor, and that is what I am asking for in the test, a simple direct connection, no oscillation, no complex circuitry. This will illustrate that even when loaded with the worst case current, the battery voltage WILL NOT fall to 0.5V

So once again, PLEASE SLOW DOWN, AND STOP READING INTO MY POSTS, just read them for what they are. A little breathing room would be appreciated as well.

Now, will you indulge me and pinpoint the exact probe placements on the diagram that I'll draw up if you agree?
