Whule I can see the point of taking power from the computer for an

Just a heads up, for those who haven't watched last week's or this week's
episode of Lost. They made it down in to the strange bunker and it
appears to be a fallout shelter of sorts. Looks to be done in a late 70's
motif. There's a full Apple II setup (two disk II drives) though they
never show the name. Wierdly they have some reel to reel stuff in the

In other words it's a kludge. Most, if not all, PC power supplies take
the reguation feedback loop from the 5V output (after all, that's the
important one in the intended application), the 12V line tracks along.
And I doubt there's a crowbar on the 12V line.
And then something fails, you don't have schematics, the parts are
unobtainable, so you grab another old PC power supply and kludge that one
to work...
Personally, I value my toys enough to give them a properly designed power
supply. One that I know is regulated from the output I am using, with a
crowbar, and with proper docuemntation.

Actually, I use compact fluorescents almost everywhere (I prefer the
higher apparent colour temperature). There are 2 specific places I don't
use them -- one is over the lathe (I am worried about a possible
stroboscopic effect making the machine appear stationary when it's not)

Many compact fluorescents use a 30-40Khz AC power source, so stroboscopic effects may not
be a problem unless your lathe's chuck rotates at a VERY high speed. You can also
make use of standard bi-pin fluorescent lamps with a fixture that uses an active
(high-frequency) ballast.
For your darkroom, you might want to look into the multiple-white-LED mains-powered
spotlights. Ebay is full of sellers eager to unload them.
I constructed a music stand lamp using three 14" CCFLs (surplus LCD backlight parts).
While not as bright as the 150w halogen lamp it replaces, the quality of illumination is
far superior--and I don't worry about burning my sheet music, although some of it
might well benefit from such a treatment...

Hmmm.. Fromt what I rememeber, white LEDs depend on a phosphor in the
package to get the white light (LED's being naturally a narrow-band
device). I would worry about the persistance of that phosphor, I think.
I also can't see the point in changing. The energy wasted by keeping
filament lamps in those positions is minimal IMHO (they're not on for
that long or that often).

They do indeed--they're basically blue with a phosphor. But the persistence is
measured in nsec, so you'd have to be pretty fast to notice it:

Part of my reason for looking at compact fluorescents is that I
specifically want 12- or 24-volt versions that can be run from a bank of
deep-cycle batteries, charged by a combination of wind turbine and solar
panels.
At my house up north, we lose power for a few days every winter when the
120mph winds take out power lines. If I was running lights off-grid, I
wouldn't have this problem and I'd have much lower bills too.

That "Cost/Benefit" analysis would have to take into account the changes
in pricing of CFLs. If you're paying $20 each, you may not ever get back
sufficient return on investment.
BUT,...
If you're paying $1 each for them, the ROI is substantial.

Again, it depends on the application. I've got a 60w incandescent installed in the
utility closet that holds my A/C, pressure tank and water heater. It sees maybe an hour
of use per year (if that). I won't live long enough to see any ROI for that $1
spent.
And how long will it be before something better (i.e. more efficient) comes by to replace
it? Technology is really the joker in the deck. A neighbor built his large house in
1992, taking adavantage of a $2K energy credit to use fluorescent fixtures for every one
of his 60 or so recessed lighting "cans". This was before solid-state ballasts
had become widespread, so he's got iron-core ballasts in all of the fixtures. Lots of
them buzz like crazy now--since these fixtures were installed before the sheetrock, with
the ballast external to the can, replacement is involved and costly. All in all, probably
a negative ROI if he can't live with the buzz. He would have been much better off
installing conventional fixtures and relamping when screw-in CFL's reached a good
price point--the screw-ins probably exhibit better efficiency than his existing setup,
too.

up to 640K + anothet 1.5M extended memory + 2 serial ports (16550s, of
course, I want to give this processor all the help it can get) and a
parallel port. Another expansion board started off life as an IBM 128K
card. I figured out it could be populated with 2 rows of 256K bit DRAMs,
and a bit of extra logic, and turned it into a 1M card. Although all the
traces for this were there, etched on the board, I can't find any mention
of this in the TechRef. And another board adds a further 2M of RAM.
There's an original IBM MDA board linked to a 5151 greenscreen monitor.
And a Colorgraph+ (Enhanced CGA card, with enough RAM for 640*200 in 8
colours, pity nothing supports it). That's linked to an NEC monitor that
was used with an Apple ][, which I modifed to add the intensity line.
The disk controller is an early IDE card, a few TTL parts, a couple of
PALs and a floppy controller chip. I added a daughterboard containing a
couple more TTL chips to flash the frontpanel drive LED when the hard
disk was accessed. It's linked to the original IBM 1.2M drive and a Teac
1.44m 3.5" drive. And to a 1.3G IDE winchester.

Good choice in the MDA card. Damned crisp characters and a rock steady
card. I went for years with nothing more. You don't have an IBM EGA
card for the color??

Rumor has it that Cameron Kaiser may have mentioned these words:
Smoke signals. Checksum's a pain, though.
I thought it was TCP/CP; RFC1149.
Yes, it has been implemented, believe it or not.

I much prefer the more durable RFC-1217 myself.

I've been meaning to run a BZFlag server the runs a simulation, but I've
not gotten around to implementing it yet.

1149 isn't realy smoke signals, though. I think IP over smoke signals
would be even more interesting.
And what of RFC 2549?

There are 2 specific places I don't use [compact
fluorescent lights]
-- one is over the lathe (I am worried about a possible stroboscopic
effect making the machine appear stationary when it's not)
I actually wouldn't worry about that, for two reasons: (1) they have a
relatively long "on" time (partly the long-persistence phosphor, partly
the width of the mains voltage peak), and thus a rotating lathe, even
if rotating at a multiple of the strobe rate, will look blurred rather
than stationary, and (2) anyone who depends solely on the appearance of
the moving parts to tell whether a lathe is on is so stupid as to have
no business near power machinery in the first place (look at the power
switch, listen for the motor, find a smooth rotating part and touch it
lightly, the ways to tell are legion).
I even went so far as to try this. I turned out everything but one
compact fluorescent and got out my (variable-speed) electric drill.
The chuck has three holes for the chuck key and thus should "appear
stationary" when spinning at 20 rps (1200rpm, the drill's rated top
end) - remember I'm on 60Hz mains power. :)
No matter how I fiddled with it, I couldn't see any trace of the strobe
effect, not even the sort I'd expect if it were spinning at half speed
and I'd thus see two ghosts instead of one steady copy. Just blur.
I also can usually see strobe effects when I wave my hand fast in front
of flickering lights like large areas of white on a CRT. I was unable
to produce more than the barest trace of that effect with the compact
fluorescent.
Still, if it makes you more comfortable.... :-)

and the second is in the darkroom (they have a significantly long
afterglow after being turned off -- several minutes -- which is a right
pain there).
I'd love to get properly daylight-balanced compact florries or 12V LED
lamps (the ones that fit the halogen lamp bases).
What about electronic ballast? That would strobe (if at all) at around
1kHz, so less flicker (which gives me a headache, the whole reason I
don't use compact florries) and less chance of strobing.

Yes, but it would tie them to the mains.
You are seriously suggestingthat the fake aquarium is a portable device?
Why would anyone want to carry one around with them?
Tony, Tony, Tony. This is *America!* You can get a device that attaches
to your vacuum (the one you clean carpets with) to cut your hair [1] (and
the fact that the company that makes it can afford *television* advertising
means there are people here that *buy* this thing). A fake aquarium powered
by a USB port seems tame by comparrison.

Whule I can see the point of taking power
from the computer for an
interface converter, keyboard, mouse, something like that, wouldn't
it be simpler if devices like the aquarium, light, etc had their own
mains adapters?

They are masters at making useless crap.
To be honest, I do not have a problem with USB. It has always worked
properly for me. Plus, it is much easier to plug USB in blindly than a D
shell.
