Claimed OU circuit of Rosemary Ainslie

[Rosemary Ainslie]

Hi Fuzzy - I think that heat measurements here are critical.  Surely Aaron's IR type number would cut it?  It only needs to be compared to ambient.  What worries me is the method to assess battery energy delivered.  But if Poynt is right then the average multmeter should also do the trick.  But this will never satisfy the purists.  That's a given.  Unless the heat values aren't replicated - in which case it will more than satisfy them.

I often wondered why you sign every post.  I think it's because you need to remind yourself.  I see that brief excursion into 'MileHigh the Mild Mannered' - has come to an end?  It was nice while it lasted.  Strange - but nice. 

I don't think you were naughty with the 'wrong learning' thing.  You were naughty with the 'pie-in-the-sky' thing.  Anyway.  It's altogether too much day for me and I've got to get through it somehow.  So.  I'll ignore your post and plod on.

That third clip was great.  I suspect that the FM kind of throws the digital sampling for a loop because the "expected" sampling point has "moved forward" by delta-t if you are increasing in frequency for example.  Your summation of all of the rectangles gets thrown off because of an FM-induced "bunching/unbunching effect."  That's my pet theory.  Nice number crunching scope!

This of course is not a problem with analog integration, there is no sampling clock anymore, you have real time "infinite" sampling going on.

Some people might not realize that a capacitor is a near-perfect integrator, that's simply what it does:  The voltage across a capacitor is the integral of i(t) dt for t = t1 to t = t2.  The operational amplifier converts the input voltage into current which charges or discharges the capacitor, performing a near-perfect analog integration resulting in an output voltage.  You measure that output voltage and that's the DC voltage reading on the digital multimeter.

It certainly is applicable for investigating the "Negative Dominant Waveform" concept.  Never heard of that one myself!  You learn something wrong every day!  lol

Great that you got your MOSETs, onwards and upwards!

MH,

As always, thanks for the positive feedback. It seems so rare these days coming my way.

By all means, please suggest a wave form you'd like to see tested with the meter and scope. I currently have another idea that will bring us much closer to the oscillation Aaron had and I commented on a little while back. I'll run this through the two "computers" and see what comes out.

Incidentally, and this is sure to stir up the quarries again, I'll go on record stating that all the wave forms that Aaron has managed to conjure up from the annals of his contraption, are indeed periodic. If it repeats (and they do), then by definition it can not be categorized as aperiodic.

Because he doesn't understand source impedance of a regulated voltage source. 

This was in reference to Harv's battery impedance plot, and his mistaken statement above.

Here's one folly in his thinking; the constant voltage source he is using in his SPICE simulation IS NOT A REGULATED VOLTAGE SOURCE. It is a pure and simple ideal source, nothing more.

For some reason he is not grasping this concept and is confusing real life voltage regulators with an ideal SPICE source. They are not the same.

For some reason Ou.com doesn't allow deletions.  So strange.  Sorry Stefan.  This one was submitted in error.
