They'd be mown down by any sort of well-regulated militia who had gone
to the trouble of training together, but the assembly (and consequent
disposal) of such a crowd of Darwin-Award winners would be great day
for the human race.

It would be another 'Bloody Sunday' event, with all the dreadful long-
term ramifications.

Not a chance. The Irish care about their relatives, but who could love
a gun-nut?

Hard on their wives and kids, but that's how evolution works.

Is this a good Socialist attitude? I mean, I respect your political
orientation, even if I don't support it, but surely that is a denial of
your principles?

Do be serious John. I'm not a good socialist - I'd have voted for Tony
Blair.
I do happen to believe that unconstrained free markets don't work very
well, but that makes me a Keynesian, not a socialist, and Keynes sat
with the Liberals in the House of Lords.

You are spot on there Bill. Heh heh heh
One experience I had of that, was at the Australian
waterfront dispute several years ago.

I was at the Darling Harbour gates here in Sydney with
many different "flavours" of picketers. I met a great variety
of people at the picket site, nurses, teachers, ordinary
concerned people like myself from all walks of life. Engineers,
politicians. loonies, nuns, people from other trade unions
lending a hand to swell the numbers.
The different view points expressed were enormous.
Some back biting and heated arguments, which worried
me (lack of unity), but it was a great atmosphere overall, the
little people standing up to prime minister John Howard and
big business.

The Maritime Union of Australia ended up decimated but not
beaten out of existence thanks to help from socialists, workers
and concerned citizens all with their greatly varying viewpoints.
The "Fair Go" is still alive and well here in Australia.

John Crighton

They have parents and families. Protecting their families is one reason
they favour guns.

Hard on their wives and kids, but that's how evolution works.

It wasn't long ago that you wrote that you were a Labour party member
when living in UK. So I thought that what I wrote was correct. Many
thousands of socialists voted for TB, even if they regret it now.

I do happen to believe that unconstrained free markets don't work very
well, but that makes me a Keynesian, not a socialist, and Keynes sat

A step too far for a late Victorian to join Labour, I suppose.

Aren't you the mental midget working on that hex-inverter switching
regulator?- zzzzzzzzzzz- what a joke- but there's apparently no project
too small for an pseudo-intellectual.....Oh yeah, and get a job before
you call yourself a chemist, just having a degree from a diploma mill
doesn't qualify you for the title.

Did you want to make a post that shows you aren't a bully, and brings
the rest of us to value your postings?


Yeah, I built Goder's circuit. Took a photo. Lit some white LEDs
with it. Measured how long it ran from a NiMH battery pack. Ran some
SwitcherCAD simulations on it. Asked for some transistor .model
statements from the wisdom of the group. Twice. Failed to get them,
sad, but didn't stomp. Modified it to a SEPIC geometry. Made an
EAGLE file for it. Had fun, took it apart. Wonder how much it would
cost to have Jim put it on one chip. Leaving the experience alone to
incubate. Noticed downloads in the web logs, felt encouraged to post
again. Hobby stuff. Design, yes; professional livelihood, no. While
you're here, you should try it.

Don't think I spit or cussed. Thought I got in Jim's kill file:
elementary, boring amateur, doesn't do closed form analysis, can't
type URL. Can't tell. Sad. Tried to do perterbation approach to
analyse on Sepic, voltage source in one cycle, current source in
another. Hope it leads back to convergent infinite series solution.
No fun, no customer, no conclusion, quit. Don't remember anyone
telling the group they'd leave forever.

Meant to go to Win's transistor LED driver next. Haven't, got
sidetracked by the recent low voltage driver. Will see if it will
drive 10 Kingbright white LEDs. I really like these white LEDs.
Going to run a string down the hall. Won't be nearly as classy as the
all LED apartment on the PICLIST. Found the data sheet on these 1W
monsters, haven't found part numbers of them at Mouser. Don't want to
ask yet. Will lurk, see if it shows up.

Did do a simulation of the recent low voltage white LED driver.
Really objected to current waveform, wanted ripple free. Won't get
involved in pulsed LED brightness thread. Monster LED data sheets say
don't, really really don't deviate from recommended current, use PWM
instead. Going for low ripple.

Put the same 10 pack of LEDs on it. Ran the simulation with .step V1
oct 1.5 24 2. Found trouble at higher voltage. Moved the capacitor
charge transistor from V+ to the collector. Got more stability. Ye
ha, but quiet, so's not to disturb the cat. Did mindless simplex
style optimization on passives. Can get about 20 V, 5mA from 1.5V
input. But the regulation is set for 10mA. Not happy. Put a
transistor in the current control loop: top of current sense feeds
base of Q3 through 200K, collector limited by 43K to V+. Also put V+
to base through 3.6Meg to help stabilize at high V+ values. Took some
LEDs off, see if regulates. Much, much better now, but not finished.

Most recent mod: http://www.jump.net/~vima/led/led_drive_bias_021.asc
Didn't announce to group, nothing worthy yet. Don't have theory,
just doodling again. Finally remembered LaPlace's name. Can't
remember how to do transform. There are company executives that were
born after the last LaPlacian I worked. Can't remember how to set up
R,C values in filter, just used big ones. Probably the reason it
hiccups at high supply. Can't find in AoE, thought it was there. May
write to .Wav file, see if it will emulate summer lawnmower sound ---
rrr rrr RRR bll bll rrr rrr RRR bll ...

Will put SEPIC geometry in place Real Soon Now.

Put aside. Thought I should make a simple 1 or 2 transistor
relaxation oscillator to understand. Set currents in the 10s of micro
amps. Really strange simulation results. Can't do it. Astonished.
Maybe just too late at night.

....

Seems more on charter than speculation about my welfare status. I
have fun. Make occasional friends. Learn some new things.

You could too: type different messages.

Sounds like you're having some real fun, Aubrey, which may be more
than we can say for poor Fred, who may very well have blown a blood
vessel in that last one!

Well, it's *supposed* to be for passing on your genes, actually, but
never mind.
Perhaps old Fred's just got very low dopamine levels in what passes
for his brain. Or maybe seratonin or noradrenaline, two other
neurotransmitters implicated in depression, dysphoria, anhedonia or
whatever it is he's got. At any rate, the way we perceive things in
life is often down to individual brain chemistry as much as the hand
that life has dealt us. For some, life's a gift; for others, a curse.

It wasn't long ago that you wrote that you were a Labour party member

I joined when Kinnock was making the Labour party electable, largely
by breaking the influence of the doctrinaire socialists who had been a
little too rampant under Michael Foot. I'm much too pragmatic to be a
doctrinaire socialist's "good socialist".

So I thought that what I wrote was correct. Many
thousands of socialists voted for TB, even if they regret it now.

They shouldn't regret it. Bad as Tony Blair is, he's no Mrs.Thatcher.

I do happen to believe that unconstrained free markets don't work very
well, but that makes me a Keynesian, not a socialist, and Keynes sat
with the Liberals in the House of Lords.

A step too far for a late Victorian to join Labour, I suppose.

Lots of late Victorians joined the Labour Party - that is more or less
when it became a serious political party. Haven't you heard of the
Fabian Society?

I've no idea why Keynes preferred the Liberals, but I suspect that it
had more to do with the politics of the time than fuddy-duddy
prejudice.
