Read closely:
"there is no acceptance by anyone that equilibrium 'must' prevail,"

Even though Art proclaims this 'must'ness, he doesn't accept it
himself and he has to rely on scraps of words from dead scientists to
convince us of his faith.

Babbling nonsense.

Actually there is much sense: there is no acceptance by anyone that
equilibrium "must" prevail (whatever that means) but by the author and
that Arthur stands alone.

Such tests as these pride of authorships statements are, fall into the
same category as oaths of allegience during the commie scare.

I think that's kind of what he was getting at. At least, it looked like a
reflection on Art's use of 'equilibrium', a use only Art seems to see. If no-
one else is bound by it, it follows that other people can devise half-wave
dipoles in accordance with Maxwell's equations, as I imagine they often do.

How precious of Art to have a Slovak sock puppet.



Two swipes with one backhander. An amusing skill.

Yeah, but that connects with a much greater mismatch.

As Paul Harvey would say "and now for the rest of the story"

The inventor asked for this reward as you described and when the
Prince discovered the cost, the Prince (using your analogy) mismatched
the inventor's head from his body.

No doubt something all inventors should consider as the price at some
level....

Funny, nice use of 'mismatched'. I don't think I'm much of an inventor, the
couple of things I came up with were small (zero-crossing switch, and analog
modulated laser diode driver, laser power meter gain stage and scale/offset
tweaker), built partly by trial and error, but they all worked reliably when
I'd otherwise have needed bigger, more elaborate and more expensive answers
made by other people. But likely have probably nothing to offer than can't be
had better elsewhere. What they did do for me, generally, was firmly
establish cost as an engineering unit. One day we might even measure it with
an SI unit. Ò^O

Well, I have to be honest and say that I haven't truly finished it. It's
based on an LM317. I have this LM317 fetish based on admiration for the old
POW radio ideas, I really think it's cool that such a ubiquitous device can
be applied so perversely to such amazing unintended uses, and given its
chances of being found, designs based on it could be buuilt even if much of
civilisation were 'bombed back to the stone age'. On a more prosaic level,
it's dirt cheap, powerful, easy to build with, and contains useful features.

The driver worked in my initial test to 50 KHz, better than the 10K most
analog mod drivers seem to favour. I tested it with a square wave and the
edges were sharp with no overshoot if I didn't push it too hard, and did some
filtering with low ESR tantalums for supply decoupling. I later discovered
LTspice. I modelled it with that and quickly saw the same waveshapes my
100 MHz scope had shown me, which was a nice reality check that proved that
LTspice could likely similaute the design and let me improve it before
rebuilding. I devised a circuit that cannot be overdriven, attempts to do so
merely broaden the peak at max amplitude, it cannot overshoot, and will
modulate to 200 KHz. The proof is in the pudding but the truth is I never got
round to baking the pudding. Bought a slower version of the op-amp I needed
but got mightily disillusioned about the laser show thing and felt that I'd
either build it and gain nothing personally from it, or no-one would even
care. Given what I'd seen, I think this is genuinely true, few would. I
hadn't even decided if I was going for SMT or through hole, and it's a tough
call because available parts seem to force a hybrid... Like the pitch-to-MIDI
system I wanted to build as an adapted version of Doepfer's R2M control
system, it got put on the back burner. But I spent a couple of years pulling
together all the tooling and design files to do it, and when I find something
to motivate me, I intend to finish both these projects.

I think this is what's drawing me to SWL. The present stopped compelling me,
so in a way I'm drawing on something that endured from further past, as a way
to revive the spark that got me as far as I did get. I never found a way to
gauge what I do, because most times I find little to suggest that what I do
has anything that people can't find better elsewhere just by throwing money
at it, and as they usually have more than me I tend to think they're probably
right. But if I can find enough motivation just to do it even though it might
amount to nothing, I will do it because I don't know what else I'm good for.

Long spiel, but I think I needed to, as part of whatever I have to do to make
it happen. Like Mulder, I want to beleive, I guess..

As you are so fond of saying, "you made the claim, you prove it",
or is you claim as empty as you head.

I have never said that, not even once. So how could I be fond of saying it?

And Art has also not once posted a single measurement, a single equation
or a single design.

And you have never done anything but snipe.

Yes, so do I, but I also occasionally make contributions, and my claims
have always had numbers and measurements behind them.

Do you know what measurements are?
