I'm on my 2nd year of running a 100 watt equiv 6500k CFL upside down and
enclosed in a globe all year long dusk to dawn. I guess the brand does
matter in this case Osram/Sylvania. And there was no indication on the
package of any severe duty specifications.

**Why would you stock up on incandescents? In a few years, LEDs will be
pretty much the standard and reasonably priced and they keep their colour
temperature when dimmed. As for experiences, mine is all good (with CFLs).
In the past 7 years, I've had two failures (out of 19 installed). One I
dropped and the other a possum sat on it. I either use CFLs or straight
tubes just about everywhere. When I really need a lot of light, I hook up my
80 Watt (or 160) halide. Either one makes a 500 Watt halogen look sick.
There are a few places in my homoe where I still have
incandescents/halogens. I can't wait to dump them. They're unreliable pieces
of shit. Give me CFLs any day. Or LEDs. Or halides, when I need them.

Arfa's problem is more to do with "green" government ramming CFL's down
peoples throats than actual performance. LCD monitors were trashed by
computer critics when they first came out (rightly so) but now it would
be a fool who buys a CRT monitor, no need for gov't intervention, the
"people" made their own decision. As for CFL reliability, the QC has got
worse, last pack of 6 from Costco , 2 were dead, one failed
spectacularly after 20 minutes, the others are fine but I doubt will
last the quoted lifetime. Also it would be useful if there was an easy
way to dispose of the blasted things.

That depends on the base used -- as well as other ingredients.
And, of course, how long you let it ripen. E.g., fruits
tend to bring too much water to the mix; sugar substitutes
result in insufficient volume (I suspect sugar also lowers
the freezing point of the mix?)

My butter pecan Rx can tolerate extended ripening before
becoming "hard as a rock" (N.B. ripening seems to be a
self-contradictory term wrt ice cream!)

You can still-freeze some Rx's while others seem to need a
dasher-on-steroids. :<

It's always fun to watch the expression on someone's face

That is, high-butterfat ice cream with low overrun. The University of
Maryland dairy store sold such ice cream, and it was a wonderful. Even the
"premium" brands don't match that quality.

Now now Philip. You know we've all told you about this behaviour before. You
know what comes next don't you ? No, don't play dumb - you do know ...
That's right, you get to go on the naughty step !

Now be a good boy, take your meds - you have forgotten again haven't you,
you naughty naughty boy - and piss off back under your antipodean stone.

On the wider field of RoHS

http://www.guardian.co.uk/environment/2010/nov/10/ducks-lead-shot

Law banning use of lead shot in duck hunts ignored

Lead pellets still used as ammunition to shoot ducks, says Wildfowl and
Wetlands Trust

* James Meikle
* guardian.co.uk, Wednesday 10 November 2010 17.20 GMT
Duck hunters are flouting the law on the use of lead ammunition.
The law banning the shooting of ducks and other wildfowl with lead shot is
being widely flouted across England, according to a government-funded study.

Seven in 10 of the ducks checked at game-dealers, butchers and supermarkets
were killed with lead ammunition, while surveys of shooters and shoot
organisers revealed that many admitted they did not always comply with the
regulations introduced in 1999.

The measures were meant to stop the death of waterbirds from lead poisoning
caused by them mistakenly eating spent shot which they mistook for food or
grit needed to aid their digestion. This was thought to account for
one-in-eight bird deaths. But no one is known to have been prosecuted for
breaking the law which could result in a £1,000 fine. The regulations also
ban lead shot being used to kill any birds below the coastal spring-tide
high-water mark or in specified wetlands.

The Wildfowl and Wetlands Trust (WWT), which wrote the report with the help
of surveys by the British Association for Shooting and Conservation (BASC),
said there had been no improvement since the trust conducted a smaller study
with the RSPB in 2002. Non-compliance remained "high and widespread".
Businesses selling duck killed by lead pellets are not breaking the law.

The checks indicated how the law was particularly poorly observed on inland
game and duck shoots. Wildfowlers shooting birds in coastal areas were less
likely to supply game outlets, the report noted.

The BASC surveys found up to 45% of those responding admitted not always
complying with the law. Some did not believe lead poisoning of wildlife was
a sufficient problem to justify the regulations and others believed lead
shot was more effective and less expensive than alternative ammunition,
including steel, tungsten and bismuth.

The WWT is calling on the government to do more to ensure the law is obeyed.
It recommends that offences are reported, and said shoot organisers should
make compliance with the law a condition of taking part, and that
game-dealers should demand that all their suppliers had behaved legally.

The BASC agrees all regulations applying to the use of lead shot should be
observed. A spokesman said: "We need to address the problems this is showing
up."

The Lead Ammunition Group, a panel established by environment department
Defra and the Food Standards Agency, is to report on the health impacts of
lead shot on both wildlife and humans next summer.

Ya but, you'd loose the fun in trying to read and figure out the
manual. A friend once bought a Japanese manufactured (long ago)
camera and the manual talked about pushing the shutter release
button and hearing the sound of a "crick". I also had a German
built camera flash that talked about "mains operating flashing",
whatever that is. It took me a long time to figure out that they
meant you could run the flash from an outlet (the mains) if the
battery was dead.

I measured the coil resistances and compared them to the values measured
by Justin Pelling with a similar Bosch washing machine motor on his
website:

'Motor diagnosis' (http://tinyurl.com/3xtnt2n)

They were within the specified range.

I therefore, purchased replacement brushes and whilst replacing them,
also opened the motor and cleaned inside including the commuator
contacts.

I reassembled the motor and fitted it back into the washing machine.
The drum now spins however, there seems to be quite a noticeable noise
when the motor spins. Anti-clockwise seems to be louder and it almost
sounds like the motor is jumping a little?

Is this normal?

Thanks.

All sorted now, after some resoldering under the connector for the
programmer - thanks all for the advice!

If anyone has the spec. for braking resistors for this (or very similar)
drive, it would be handy - according to the book for another ABB drive (same
rating, a few years newer) I'm looking at a 32 Ohm, 12 KW peak resistor if I
want "heavy duty" (emergency stop from top speed) braking... I may have to
Improvise!

Ask on the metalworking group.

Hi. This monitor has a strange fault. When switched on without signal
the screen illuminates and the "check signal cable" display moves around
the screen as it should. However, when I connect a signal, I get a brief
screen of garbled lines (very brief indeed) then the backlights go out.
The power LED also goes off, though it comes back on again, but with no
display.

I have checked the various capacitors on the PCB with an ESR meter, also
the power supply in the same way. The voltages coming from the power
supply appear correct.

Has anyone experienced this fault? The RGB signals go to a SE7888 i.c.
which appears to drive the screen. I assume at least part of this is
working due to the no signal display being good. Is it possible that
something has failed internally in this i.c.? Could the solution be
simpler than that (my experience has shown these chips seldom fail)

Does anyone have one laying around in a scrap monitor?

Thanks.

Is the computer perhaps set to a display resolution that the monitor doesn't
support? I have some older LCD/TFT monitors that don't support over
1024x768 (one doesn't support over 800x600!), and they simply will not show
video at anything higher.
