(10) Technologies That Deserve To Die

You don't know much about displays.

They spent ten years getting refresh rates up, and your lame ass is
thinking in the stone age if you think 60Hz is OK, particularly for
CAD or gaming.

Much less Putting up a DVD presentation, windowed.

Are you ever going to contribute something *worthwhile* and productive to
the group? We can get endless quanta of bickering and name-calling from
other, more entertaining sources...

Hi Dark,

The fan that Lambda used was anything but cheaply constructed. It
had steel cased ball bearings, and a fan good signal line. It wasn't
the fan's fault that lambda put the fans at the end of the heat sinks
and sucked the hot air through the fan. It basically cooked the grease
to death.

But, a 115V fan would have still run longer because they typically
have 16W motors, and this 12V fan was only 5W, IIRC. Since the
fan was built into the supply, its load was included in the efficiency
rating of the supply. It had two of these fans per supply, so they
were wasting around 10W out of 2KW in fans.

The supplies I last fixed were in color printing equipment used by
a large local printing firm. They had dozens of these printers, and
each had a half dozen of these power supplies. The supplies went about
5 years before the failures started showing up.

Are the fans in the environment, or outside? If the fans and
their motors/bearings, etc are in the environment, then they are
special fans indeed! Running from -40C to +200C. I would never
attempt that, and would put the motors outside of the environment,
and only put the fan blades in the environment.

If they are outside of the environment, then ho hum!

Last week one of our servers at work had a bad fan, and one of the
guys pulled it out to replace it. Turned out that the replacement fan
had a foot shorter pigtail, so I had to cut off the old pigtail and
add it onto the new fan with some heat shrink tubing.

So I pulled the blades off the old fan to see what happened, and the
8-pin DIP chip on the PC board was burned up. I didn't do much
further checking because it still stunk like it was burned up.
Anyhow, I don't think that would be a problem with a simpler fan that
used a regular AC motor.

Chassis are supposed to be positive pressure. That would be fans
pushing air in, not sucking already heated air out.

Poor design.

Yep, you're right. I'm such a lame twat. All I ever do is sit in the
newsgroups and slam other innocent people and spew falsified information due
to my insecurities and poor childhood upbringing. I should be executed with
a dull butterknife - anyone willing to help? I'm pathetic. I'm a loser. I
can't assess a rock if it hit me in the head. And I thought Credence was a
band. Sheesh, sorry to waste your time m'lord. I'll be committing suicide
now, no need to call in the cavalry. Sorry again for any inconvenience, have
a nice life.

Send the body to Santa Cruz...We will throw it in the chimney! ...it's
colder than crap here!
Now I know this will start another thread....my idea of cold is
40......so the whole gang from up north are going to tell me what cold
really is! ......Let it hit the fan!............Ross

I saw where a death-row inmate donated his body to "science." After he was
killed by lethal injection, they immediately took his body and froze it in a
block of ice. Then they took this to the lab, where they proceeded to cut it
into over a thousand "slices" with a bandsaw. Each of these slices were then
scanned into a digitizer and reconstructed into 3D. So now they have a
teaching model of a human being, that can be looked inside without any
incisions.

I guess that is a donation to science... would kinda suck to be placed back
into your casket in 1000 pieces though.

I saw that again recently and man what a contrast to
the type of science-fiction there is today, but still a
heck of a concept. Full-scale Hannibal Lechter???

Er, cremated? I think they used something like a microtome.

They used a CNC controlled Bridgeport milling machine. They body was
filled with liquid, and frozen solid. The milling machine removed small
layers (1 mm, I think) and they photographed what was revealed, end
on.

When they were done, there was nothing left but mill shavings. All of
the pictures are viewable on the internet at:

IIIRC, they milled off a layer, misted it with water to get a good
surface to photograph and then went on to the next.

Gross swarf.

This was done more than once. The most recent one was done with the
frozen BP. I think Scientific American did a story on it. Previously,
in the 1930s (?) it was done in cruder (maybe 1/4") slices, both to a
man and a woman. Unless it's been moved, the slices were on display
(but semi-hidden) in the Chicago Museum of Science and Industry,
appropriately sandwiched between glass sheets and pickled in
formaldehyde. The museum is well worth a visit if you're in the area.

You're a reiterating little chimpanzee.

I guess that'll be a "no", then. Imagine my lack of surprise.

Some slices taste better than others.
