Anyway, about the Pentium III that you seem concerned about. Has anyone
considered the possibility that Intel is going for the dictatorship
markets such as Singapore, China etc who would prefer this to the

about the load-cells used in electronic scales--how _do_ they return those
to zero after something is weighed? Must be some sort of dynamic
balancing circuit for a bridge circuit.
That peak-to-peak question has a problem, and I'm rather sorry that
they're emphasizing p-p in this course. 10v p-p is 5v peak, so the rms
value is gonna be something like .707 x 5v, which is something like 3 1/2
volts, which isn't on the list of answers. None of the choices are
correct, including that last "insufficient information" one.
It's an okay test, but certainly not the best I've ever seen. Anyone know
where it came from?

Well, a scale assembly not being overloaded shouldn't be stressed
beyond it's yield point (i.e., It should stay within its plastic
range), so that it returns pretty much to zero when the sample is
removed. And the scale gets re-zeroed during power-on, anyway.

No, what we REALLY need here is a test that checks to see if you're
competent to deal with REAL-WORLD design issues. I will humbly
(yeah, right) now offer a few example questions to get us started:
1. Your management has handed you a set of design specifications which
violate all known laws of physics, including several from the "Star Trek"
universe. What should you do?
2. Supplier A offers components which are technically superior and available
at half the cost of supplier B's, but supplier B gives you better T-shirts.
Whose
party do you try to crash at Comdex?
3. Through basically clumsy application of a test probe and an unfortunate
error
regarding which terminal was the 400V supply, you have destroyed a prototype
representing 300 man-months of effort and an R&D budget equal to that of
some
developing nations. Who should you blame this on, and how?
4. List, in descending order of generated volume, the top 5 components in
terms
of producing the most smoke when incorrectly connected.
5. Give at least three examples of politically-incorrect color-code
mnemonics.
6. How many "Dilbert" calendar pages are required to fully cover the walls
of
the average R&D engineer's cubicle?

Both of them, because the one with the more expensive parts and T-shirts

After several weeks of testing you have isolated the cause of
a major bug, and a quick five minute alteration using a ball
point pen and an exacto knife will fix it, but ISO requires
you to use a new $300 tool that will take six weeks for delivery.

Ya wanna hear something sad? This is a perfect description of the
electrical exhibit at the Carnegie Science Center in Pittsburgh. They use
lasers of unexplained function across the ceiling and a big Tesla coil
that Carnegie-Mellon University gave them. Since the power supply of the
Tesla coil didn't make enough noise, they added a 60Hz fire alarm buzzer.
No explanations of anything are offered, as is generally the case
throughout the entire museum.
I'm afraid that CSC is quite typical of the average science museum in the
US these days. It's one of the reasons I started How Things Work.

Is _anyone_ giving away junk at trade shows anymore? Things are
exceptionally thin in power engineering. I think I got a Reddy Kilowatt
worry squeeze ball, a pinwheel, and a pen at the IEEE Computers in Power
Systems conference.

Those will do it. We were experimenting with aspirin tablets
rubber-cemented to 120 ohm 1/2 watt resistors for installation across the
power line in the audio console of a radio station I was at, but I don't
recall how that came out.
An excellent test. Thank you.

I don't know, but my boss keeps insisting that I am earning the salary
of an average engineer, so there must be one out there somewhere.
When I asked him how they arrived at that average, he said that HR had
determined the average salary for engineers in this area. He didn't
like it when I asked if that meant that since there aren't many
engineers in this area that they had averaged my two coworkers and I,
and then told us we were earning the average...

Oh, this one is easy.
Make sure you inform your sales director that you
can't sign for the amount needed on the P.O. and

When I was working as a tech in 1975, I asked my boss how he comes up with
cost estimates for a project. One of the things he factored in was that a
good technician 'can either install or burn out about $75 worth of parts a
day'.
I now work in microwaves, and my first tech blew out $750 work of custom
switches within his first 2 weeks, so I figured he was right on schedule.

Simply rewrite the procedure so that you can use the cheaper tools. This
will of course mean that you send some time walking the new procedure
through the procedures update chain and, may take longer than the delivery
of the new expensive tool.

The answer is both but in which order. I suggest that the order is do the
cheapo stand first (grabbing free samples in their carrier bag) and going
and use the cheapo (but good) products as a prod to the other company to
give you a pile of T-shirts anyway. Then, away from the show, order the best
VFM product you can lay your hands on (probably from company C, the rep of
which is a drinking buddy of yours).

A bug that has taken several weeks to isolate is an expensive
bug. A quick hack to cure it is inappropriate. The cure must involve
the expense of writing up a report in such a manner that expensive
time is not wasted again. The use of a $300 tool is not a
significant cost.

Couldn't agree more.
I think the best way of dealing with the situation is to let Milosevic
get on with it, otherwise these old ethnic feuds run and run. We need a
man like him to provide the final solution to the problem.
On our part, we should seal the borders against these refugees and
'asylum seekers'. I certainly don't want troublemaking scum coming to
England under the pretext of genocide.

There is a case for that. In most situations where there has
been war-mongering as an excuse for empire building,
and the colonial power has left, there is usually civil
unrest. The old tribal feuds have remained under the
false notion of a "Pax Romana".
This is true even in what may be the last of the
Britisher's empire building in Ireland.
> We need a
>man like him to provide the final solution to the problem.
I don't agree with that. If what is reported in the Western
World is true (and it ususally isn't) then Mr. Milosevic
has a lot to answer for. However, two wrongs don't
make a right, and the actions by Clinton and Blair lay
them open to a UN-led prosecution for war crimes.
England is no different to Serbia, for we recently had
prima facie evidence of war crimes in the Malvinas/
Falklands campaign, and these were hushed up in a political
furore.

Hmm. So if you're visiting someone, and his neighbor walks over and shoots
you for trespassing, it's your fault? According to NATO, they were in

No, the bands are of different colours, but they all have the same
value. Since the value is averaged over all possible colours, it is
infinitesimal, thus conforming to the best PC principles.

Imagine you are a technician, with what modestly could be called experience
in a particular electronics field. Not academically qualified to be an engineer
but have enough experience to adequately practice as one in your field of
expertise.
An engineer comes into your workplace to improve the workings and efficiency
of a particular high priced piece (eg ~$5000) of equipment that your company
constructs and markets. He subsequently reduces the efficiciency, increases
the component count and cost of the item in question in spite of queries and
demonstrations by you using the equipment, as to the wisdom of his changes.
He also adds components to create circuits that have functions that can be
served by more far more efficient methods.
Management don't appear to be aware, or really care, as long as the new
engineer is appearing to do his job. Management are not electronic engineering
types, they just manage the company. The item in question is not a high quantity
selling item.
How do you overcome your frustrations and try to initiate genuine improvements
when your engineer is hostile to your suggestions (as you are only a technician,
and
are here to support me) and management do not look kindly at bypassing the
chain of command?
Leaving the company is too simplistic as you believe in the equipment's
potential
to be a big hit if improved correctly.

I wish my Simpson or Triplett could match that. On the other hand,
active meters, such as DVMs and VTVMs simply have a flat input
impedance, usually.
Radio Shack sells kick-ass meters thet rival Fluke, SD, and Beckman,
at a fraction of the cost. You really should give them a try sometime.

either A or B, unless you're using that damn Simpson 260 mentioned

then B only, provided it's not in one of my circuits, in which case A,
because it's probably being used as a zener.

One night when his charge was pretty high, Micro-Farad decided to seek
out a cute little coil to help him discharge.
He picked up Milli-Amp and took her for a ride in his Megacycle. They
rode across the Wheatstone Bridge and stopped by a Magnetic field with
flowing currents and frolicked in the sine waves.
Micro-Farad, attracted by Millie-Amp's characteristic curves soon had
her fully charged and proceeded to excite her resistance to a minimum.
He gently laid her at ground potential, raised her frequency and
lowered her reluctance.
With a quick arc, he pulled out his high voltage probe and inserted it
in her socket, connecting them in parallel. He slowly began short
circuiting her resistance shunt while quickly raising her thermal
conductance level to mill-spec. Fully excited, Milli- Amp mumbled
"MHO...MHO...MHO"
With his tube operating well into class C, and her field vibrating
with his current flow, a corona formed which instantly caused her
shunt to overheat just at the point when Micro-Farad rapidly
discharged and drained off every electron into her grid.
They fluxed all night trying various connectors and sockets until his
magnet had a soft core and lost all of its field strength.
Afterwards, Milli-Amp tried self-induction and damaged her solenoids
and with his battery fully discharged, Micro-Farad was unable to
excite his field. Not ready to be quiescent, they spent the rest of
the evening reversing polarity and blowing each others fuses.
BUT WAIT!!! There's M O R E !
===============================
Micro was a real-time operator and dedicated multi-user. His
broad-band protocol made it easy for him to interface with numerous
input/output devices, even if it meant time-sharing.
One evening he arrived home just as the sun was crashing, and had
parked his Motorola 68000 in the main drive (he had missed the S100
bus that morning), when he noticed an elegant piece of liveware
admiring the daisy wheels in his garden. He thought to himself, "She
looks user-friendly. I'll see if she'd like an update tonight."
Mini was her name. She was delightfully engineered with eyes like
COBOL and a Prime mainframe architecture that set Micro's peripherals
networking all over the place.
He browsed over to her casually, admiring the power of her twin,
32-bit floating point processors and enquired, "How are you,
Honeywell?" "Yes, I am well," she responded, batting her optical
fibers engagingly and smoothing her console over her curvilinear
functions.
Micro settled for a straight line approximation. "I'm stand-alone
tonight," he said. "How about computing a vector to my base address?
I'll output a byte to eat, and maybe we could get offset later on."
Mini ran a priority process for 2.6 milliseconds then transmitted 8K.
"I've been dumped myself recently, and a new page is just what I need
to refresh my disks. I'll park my machine cycle in your background and
meet you inside." She walked off, leaving Micro admiring her solenoids
and thinking, "Wow, what a global variable. I wonder if she'd like my
firmware?"
They sat down at the process table to a top of form feed of fiche and
chips and a bucket of Baudot. Mini was in conversational mode and
expanded on ambiguous arguments while Micro gave occasional
acknowledgments, although in reality he was analyzing the shortest and
least critical path to her entry point. He finally settled on the
old,'Would you like to see my benchmark routine?' but Mini was again
one step ahead.
Suddenly she was up and stripping off her parity bits to reveal the
full functionality of her operating system software. "Let's get BASIC,
you RAM," she said. Micro was loaded by this stage, but his hardware
policing module had a processor of its own and was in danger of
overflowing its output buffer, a hangup that Micro had consulted his
analyst about. "Core," was all he could say, as she prepared to log
him off.
Micro soon recovered, however, when Mini went down on the DEC and
opened her divide files to reveal her data set ready. He accessed his
fully packed root device and was just about to start pushing into her
CPU stack, when she attempted an escape sequence.
"No, no!" she cried. "You're not shielded!"
"Reset, baby," he replied, "I've been debugged."
"But I haven't got my current loop enabled, and I can't support child
processes," she protested.
"Don't run away," he said, "I'll generate an interrupt."
"No, that's too error prone, and I can't abort because of my design
philosophy."
Micro was locked in by this stage, though, and could not be turned
off. But Mini soon stopped his thrashing by introducing a voltage
spike into his main supply, whereupon he fell over with a head crash
and went to sleep. "Computers!" she thought as she compiled herself.
"All they ever think about is hex."

magic smoke /n./ A substance trapped inside IC packages that enables
them to function (also called `blue smoke'; this is similar to the
archaic `phlogiston' hypothesis about combustion).
Its existence is demonstrated by what happens when a chip burns up --
the magic smoke gets let out, so it doesn't work any more. See smoke
test, let the smoke out.
Usenetter Jay Maynard tells the following story: "Once, while hacking
on a dedicated Z80 system, I was testing code by blowing EPROMs and
plugging them in the system, then seeing
what happened. One time, I plugged one in backwards. I only discovered
that *after* I realized that Intel didn't put power-on lights under
the quartz windows on the tops of their
EPROMs -- the die was glowing white-hot. Amazingly, the EPROM worked
fine after I erased it, filled it full of zeros, then erased it again.
For all I know, it's still in service. Of course,
this is because the magic smoke didn't get let out." Compare the
original phrasing of Murphy's Law.

On a similar theme
The Tail of Polly Nomial
Once upon a time (1/T) pretty little Polly Nomial was strolling across a
field of vectors when she came to the boundary of a singularly large matrix.
Now Polly Nomial was convergent, and her mother had made it an absolute
condition that she must never enter such an array without her brackets on.
Polly, however, who had changed her variables that morning and was
feeling particularly badly behaved, ignored this condition on the basis
that it was insufficient and made her way amongst the complex elements.
Rows and columns closed in on her from all sides. Tangents approached
her surface. She became tensor and tensor. Quite suddenly, two branches
of a hyperbola touched at a single point. She oscillated violently, lost all
sense of directorix, and went completely divergent. As she reached a
turning point, she tripped over a square root that was protruding from
the erf and plunged headlong down a steep gradient. When she rounded
off once more, she found herself inverted apparently alone in a
non-Euclidean space.
She was being watched, however, by that smooth operator, Curly Pi,
who was lurking inner product. As his eyes devoured her curvilinear
coordinates, a singular expression crossed his face. He wondered,
was she still convergent? He decided to integrate improperly at
once. Hearing a common fraction behind her, Polly rotated and
saw Curly Pi approaching with his power series extrapolated.
She could see at once by his degenerate conic and his dissipative
terms that he was set for no good.
"Arcsinh!" she gasped.
"Ho, ho," he said. "What a symmetric little asymptote you have; I
can see that your angles have lots of secs."
"Oh, sir," she protested, "keep away from me. I haven't got my brackets on."
"Calm yourself, my dear," said our suave operator, "Your fears are purely
imaginery."
"I, I," she thought, "Perhaps he's not normal, but homologous."
"What order are you?" the brute demanded.
"Seventeen," replied Polly.
Curly leered. "I suppose you've never been operated on?"
"Of course not," Polly replied quite properly, "I am absolutely convergent."
"Come, come," said Curly Pi. Let's go off to a decimal place I know and I'll
take
you to the limit."
"Never," gasped Polly.
"Abscissa!" he swore, using the vilest oath he knew. His patience was gone.
Coshing her over the coefficient with a log until she was powerless, Curly
removed her discontinuities. He stared at her significant places and began
soothing her points of inflection. Poor Polly! The algorithmic method was
now her only hope. She felt his hand tending to her asymtotic limit. Her
convergence would soon be gone forever.
There was no mercy, for Curly was a heavyside operator. Curly's radius
squared itself; Polly's loci quivered. He integrated by parts. He integrated
by partial fractions. After he cofactor, he performed Runge-Kutta on her.
The complex beast even went all the way around and did a contour
integration.
What an indignity to be multiply connected on her first integration. Curly
went
on operating until he had satisified his hypothesis, then he exponentiated
and became completely orthogonal.
When Polly got home that night, her mother noticed that she was no longer
piece-wise continuous but had been truncated in several places. But it was
too late to differentiate now. As the months went by, Polly's denominator
increased monotonically. Finally she went to the hospital and generated a
small but pathological function which left surds all over the place and
drove
Polly to seek analysis.

This is the renowned "Smoke Theory of electronics."
Theory:
Hypothesis: All Electrical components are MFGd with smoke inside them.
Supporting Evidence. Component failure is usually preceded be a release of
smoke by that object. NOTE: sometimes that smoke is not visible or observed]
Synthesis: It's the smoke that allows them to have Electrical Function.
Conclusion: If you let all the smoke out of an electrical component, if will
cease to operate.

Reminds me of a comment in a book on do-it-yourself computer maintenance:
"If there's white smoke coming out of your disk drive, you probably have a
hardware problem. Unless, of course, your disk drive has just been
elected Pope."
