This just gets funnier and funnier...

Holy cow... I'm in the middle of a flame war over whether tying wire into
an overhand know is an original, creative idea.

You know that theory that, if you had a bunch of monkeys typing randomly,
eventually they'd produce the works of Shakespeare? Well, Usenet has
proved that it's not true.
Certainly not in the case of the pathetic dolt whom thinks his knotty
idea is an example of talent OR skill.

The only talent the dopey fuck has is the ability to show everyone
around him how utterly SIMPLE the clueless fuck really is.

A description should suffice [rum disclaimer inserted here]:

Yes -- I have eight output transformers in parallel from the same

channels are working correctly, so the current shares evenly, and all
the caps are happy (the maximum supply is 5A, so they each see a
maximum of 5A / 8 = 0.6A peak, so the RMS ripple is under 0.42A, fine
for a chip tantalum, though I have ceramic specified at the moment).
But under fault, the whole 5A could flow into just one channel, which
makes things "interesting".  I may implement a "max-of-channels"
current limit for this.

Under this fault condition in the fault current passing through the
tantalum cap, or just visiting the neighbourhood?

energy density detonates tantalums, don't get them hot and
charged at the same time.

What usually detonates them is high peak current, or equivalently high
dV/dT.

No, the worst thing about tant. caps is they get put in bakcwards*,

*MANY* moons ago, my boss was the Tantalum Cap Tzar for the corporation (how
he got that "distinction", I haven't the foggiest).  We were having all sorts
of problems with fires caused by tants in backwards.  Everything was tried,
three pins (-+-), four pins (-++-), big lead/little lead, fuses, everything.
No matter what, something like 1% of them got stuck in backwards (even to the
point that when all else went right 1% were in the tubes backwards).

One day the manager of the local manufacturing/stuffing department called
complaining that his "girls" were getting sore thumbs from sticking the
capacitors into the boards.  Yep, they were big/little lead caps and they were
trying really hard to put the big lead in the little hole.  They'd done a few
thousand that way.

I spent an hour today, trying to figure out why the current limit
kept turning on, at ~3 volts, but only under a good load???

I had a bunch go off about 2" from my ear, while I was leaning over the bench
try to figure out why the supply was limiting (I always brought systems up the
first time with the supply in constant current mode).- Hide quoted text -

Yeah... a backwards cap finally 'dawned' on me and it took less than
30 seconds to lay my fingers on the problem. New run... they're all
in backwards, except for a few I guess.

Does under voltaging (sp) make a few last longer?
I swear I've had stuff powered up for few hours, and then get pictures
sent of a 'brown' tantalum, in backwards.

customers!)

Not necessarily. Yes, you cannot have a symmetrical wind because
the cables are intertwined, but you still can bind them neatly.

That would be ugly hanging from the wall warts in my kitchen.
Wall wart cables are the worst.

I straighten every fold and kink in mouse and keyboard cords.
No keyboard or mouse cords here.

I also flattened out all the creases in my pc's IDE ribbon
cables.
I did that, when I had IDE cables. I used to remove every little
crease. And I shortened them. And removed unnecessary headers. I
was meticulous when it came to PC wiring. Currently, I am not as
involved with PC hardware stuff. But I still unwind wound power
cables. Before cordless, I always made sure that telephone handset
cords were correctly unwound. Usually noticed other peoples
telephone cords wound up.

I don't suffer from obsessive compulsive disorder (OCD) as much
nowadays.

But still enough to annoy the hell out of most everyone here. Perhaps your
statement above explains much. Plus you seem to be getting what you crave: a
lot of attention. Even if it's bad, it's still attention. When a dog
constantly begs, paws, and barks for attention, even if you yell at him,
it's better than being ignored, so he is positively reinforced to continue
his annoying behavior. So, you sure are getting it here. But respect, heh,
not so much...
