The high price of Fluke is for their quality and robustness. Every
other meter brand I've used is not robust enough to handle prolonged
heavy use. B&K, Triplette, etc, all break under heavy use. One of
the most common points of failure are the test lead connector sockets.
I've tossed many a DMM due to continuity failure at the sockets.
Never a Fluke. I'll be willing my Fluke to my kids.

If Fluke has a failing, it's their failure to support older equipment.
Their stuff is so good it last forever and they will often quit
providing accessories for discontinued models. Also, some of their
accessories have not matched the quality of their meters. They used
to have some extremely handy spring-steel extendable test leads that
were almost guaranteed to break due to poor design and the breakable
part was not replaceable. But, for their few shortcomings, they're
still the best meters on the market, regardless of price.

Any permanent wiring (inside the walls) will likely be solid wire, but
any portable cables (phone to wall outlet) should be stranded to
survive the flexing they experience.

Actually, hardly any of it is. Just the indoor stuff, pre-plugged, as
Peter said.

Discarded sections of 25-pair telephone cable are great for getting wire to
breadboard with. Um, you're not thinking of splicing into active wiring,
are you?

Some of the major reasons for using a wall wart are

1) EU and some other areas state that all equipment must be
supplied with the correct mains plug already wired up.
(the fact that even more people cannot rewire a plug safely
has not been recognised, we now have more peoplr coming
through who do not understand mains wiring colour coding
and related issues)=.

2) Cost of manufacturing different models for different mains
voltage.

3) Size of the unit the consumer is buying is smaller.

4) Other safety or similar issues are not the primary concern
the three above are, except that the appliance has to have
less safety measures.

In most cases the power efficiency and how much heat these wall warts
generate, is amazing. If more effort was put into using more power efficient
wall warts, I am sure we would save more electricity generation than
turning all the TVs off instead of standby.

Yes!

The wall wart became a design
pattern for a reason: it hits an almost perfect equilibrium between
cost, usability, safety and reliability.

Wall warts also make getting safety certification easier - don't have
to submit the device for approval, just the already approved wall wart
you bought from some other manufacturer. They make a cheap and dirty
way to make a device universally powered.

And they probably waste a lot of energy. Perhaps as the switching
wall warts become smaller, more bullet proof, and more efficient, I'll
have to rethink my opinion.

But this vociferous reaction about how
dangerous it is - is just not justified.

Yes it is.

Fully seconded. If people need to be shouted at from a close distance
to avoid a realistic danger of accidentally electrocuting themselves
or other people, then by all means, let's get them shouted at.
Violent explanation never seriously hurt anyone --- violent
electricity does. A much more brutal, hands-on approach (such as:
showing the apprentice a realistic electrocution accident on video)
would be even better, but we can't do that over the internet.
Depends on personality and conditioning - I find I tend to ignore
yelling, shouting, advertising, appeals to emotion, or just
"background noise," and tend to pay more attention to an appeal to
reason.

Many of us learned on vacuum tubes where the plate supply was an
order of magnitude more lethal than any mains voltage one might

In a word, no. I once went to Home Depot and got some jacketed 4-

intended for internal phone circuit wiring.

Take just a low sat BJT instead, it needs only half the voltage. You also
need a Schottky diode antiparallel to the b/e junction to avoid charging up
the output capacitor and an appropriate current limiting resistor, maybe 33R
before.

-5V (or -3.3) is easily achievable with a small device and a few caps
using a charge pump device. For low currents, it's easy to get a
regulated voltage.

See the LM2660 as an example

On issue after issue I have been ashamed of my president.

He lied about Iraq, and still lies. 2,500 of our citizens have been

adventure that not only was started falsely, but will continue and end
disastrously. Why he has done this to us is a mystery. It appears that
his immature understanding of the world allowed the neo-cons in his
administration (generally the code word for Jews who ardently support
Israel) to sell him lies in order to get a massive attack on Iraq. They
believed that Israel would be helped. Your tax dollars and son's blood
at work! How many Jews have died in this war on behalf of Israel? I am
ashamed.

His immaturity stirred up the North Koreans, and his immature refusal
to talk has pushed the Syrians and Iranians into a corner. He is making
things much worse for us. The world has watched our arrogance and has
come to mistrust and hate us even more. I am ashamed.

He has used my Christian born-again faith to justify much of what he
has done, and even now has talked about some kind of messianic purpose
in his fight against terrorists on behalf of Israel. How dare he use
the name of Christ to murder. I am ashamed.

And now today I believe that he really hatched this Israeli attack on
Lebanon. He is rushing, as I write, devastating 5,000 lb bombs to
Israel. How many children's blood, and other innocents, will be
splattered with our tax dollars at work in Lebanon? I heard an
administration spokesman this morning say, "We support the Israei
attack completely. After all, they are fighting the terrorists for us".
Since 1982 when they tried to drive our troops our of Lebanon, they
have not hurt an American. And they have never hurt an American in
America. So I say bullshit to this argument. I am ashamed.

And then there are the Palestinians. Those awful people. They just
can't accept that Israel took all of their land, homes, jobs, orchards.
So what if they live in a virtual prison with nothing, nothing,
nothing. So when they are bad little boys and girls, America MUST send
drones to fire rockets at them. This morning a 3 year old girl was
blasted, beyond recognition as a human, by our tax dollars at work. I
am ashamed. They have nothing, nothing, nothing. If Jesus were alive
today, would he be visiting the power centers in Jerusalem, or the
slums of Gaza. I know where MY savior would be. I am ashamed. I am

Applauding While Lebanon Burns
by Norman Solomon


Syndicated columnist Richard Cohen declared in the Washington Post on
Tuesday that an-eye-for-an-eye would be a hopelessly wimpy policy for the
Israeli government.

"Anyone who knows anything about the Middle East knows that proportionality
is madness," he wrote. "For Israel, a small country within reach, as we are
finding out, of a missile launched from any enemy's back yard,
proportionality is not only inapplicable, it is suicide. The last thing it
needs is a war of attrition. It is not good enough to take out this or that
missile battery. It is necessary to reestablish deterrence: You slap me, I
will punch out your lights."

Cohen likes to sit in front of a computer and use flip phrases like "punch
out your lights" as euphemisms for burning human flesh and bones with
high-tech weapons, courtesy of American taxpayers.

In mid-November 1998, when President Clinton canceled plans for air attacks
on Iraq after Saddam Hussein promised full cooperation with UN weapons
inspectors, Cohen wrote: "Something is out of balance here. The Clinton
administration waited too long to act. It needed to punch out Iraq's
lights, and it did not do so."

The resort to euphemism tells us a lot. So does Cohen's track record of
sweeping statements on behalf of his zeal for military actions funded by
the US Treasury.

On February 6, 2003, the Washington Post published Richard Cohen's judgment
the morning after Colin Powell made his televised presentation to the UN
Security Council. "The evidence he presented to the United Nations -- some
of it circumstantial, some of it absolutely bone-chilling in its detail --
had to prove to anyone that Iraq not only hasn't accounted for its weapons
of mass destruction but without a doubt still retains them," Cohen wrote.
"Only a fool -- or possibly a Frenchman -- could conclude otherwise."

Cohen's moral certainties are on a par with his technical ones. While he
condemns rockets fired into Israel, he expresses pleasure about missiles
fired by the Israeli government. That the death toll of civilians is far
higher from Israel's weaponry does not appear to bother him. On the
contrary, he seems glad about the killing spree by the Israeli military.

In a column with bigoted overtones ("Israel is, as I have often said,
unfortunately located, gentrifying a pretty bad neighborhood"), Cohen's
eagerness to support additional large-scale bombing by Israel is thematic.
Consider this passage: "Hezbollah, with the aid of Iran and Syria, has
shown that it is no longer necessary to send a dazed suicide bomber over
the border -- all that is needed is the requisite amount of thrust and a
warhead. That being the case, it's either stupid or mean for anyone to call
for proportionality. The only way to ensure that babies don't die in their
cribs and old people in the streets is to make the Lebanese or the
Palestinians understand that if they, no matter how reluctantly, host those
rockets, they will pay a very, very steep price."

Such phrasing is classic evasion by keyboard cheerleaders for war: "The"
Lebanese. "The" Palestinians. "They will pay a very, very steep price."
Meanwhile, in the real world, the vast majority of the victims of the
Israeli onslaught are civilians being subjected to collective punishment.

Cohen -- like so many others in the American punditocracy -- depicts the
death of an Israeli civilian as far more tragic and important than the
death of an Arab civilian.

There's something really sick about such righteous support for civilian
death and destruction.

Osama bin Laden, meet Richard Cohen.
