From the format of your post(s),
I would have sworn that you post from Google Groups--but nope.

Folks on Usenet like to see a bit of the previous post
included with (actually, above) the text of your post.
This is called **context**.
If you observe how most folks post, you'll see what I mean.

Most newsreaders blockquote the entire previous post for you
so that you can easily snip out those portions which don't apply,
leaving just enough to give context to your addition.

Rich Grise (pointedly) remarks on context here:

The sub-thread was about Google posters;
you can easily see why I figured that you posted from there.

you that both Paul and I have massive personal electronics-book

seeking to expand our holdings. The web simply doesn't hack it.
But I agree textbook prices over $100 is crazy. The addition of
CDs of dubious value, accompanied by $180+ prices, is an outrage.

Curiously, when I offered this for free only one person called me, and
on my returning his call he never called back.

The 545B with a dual trace 1A2 plugin is too good a scope to simpy
throw out, so I've decided to keep it in service for still another 10
years where it is useful to me on the repair of Tek 465, 485 oscopes,
Hp 1741A storage scope models, as well as CDV700 geiger counters and
CDV750 dosimeter chargers.

Consider my free offer to be now withdrawn, leaving me to wonder about
the techincal apptitude of today's students and technicians who would
pass up a free deal like that which I posted!

Maybe because they guess that the 545B has no "Autoset" knob...
and no port for the USB-Stick for saving the screenshot...

My first personal scope twenty years ago was a 545A and i still have it,
but it has to live now in the neighborhood with some younger tek's

FOR IMMEDIATE RELEASE

Andy Gussert Elected President of AFT-Wisconsin

Message of Labor Unity Overwhelmingly Endorsed

MADISON, Wis. - Andy Gussert was elected President of AFT-Wisconsin - along
with Kathy Kreul as Secretary and Deb Ausman as Treasurer - at the annual
convention in Oconomowoc last Friday.

Gussert adjourned the annual convention thanking delegates, saying "You've
sent a clear message. We are stronger when we stand together, and we have
power when we unite." Rank-and-file delegates representing over 16,000
members endorsed the message, with Gussert receiving 76 percent of the vote,
the largest margin of victory in a contested election in decades. He ran on
a platform of bringing together diverse factions within the organization,
and bringing more young leaders into the organization.

"Our strength is in our diversity," said Gussert. "Our members give so much
back to the community - everything from teaching our children to retraining
displaced workers to researching stem-cell technologies and representing the
underprivileged. I'm honored to work people who are devoted to public
service." AFT-Wisconsin is a union of professionals, representing employees
in over 500 different job classifications, including doctors, dentists,
pharmacists, attorneys, administrative staff, teachers and professors.

Gussert, age 36, takes over at a time when organized labor is struggling to
appeal to appeal to younger members, while retaining the expertise and
experience of long-standing labor activists. Many new leaders under the age
of 40 were also elected, including Michael Childers, Richard Hay, Chris
Romine and John Burger.

"We are passing along the baton to a new generation," said retiring
President Bob Beglinger, who is leaving after six years of service as leader
and over 30 years of service on the executive board. "Andy Gussert
represents our future, and our future looks bright."

AFT-Wisconsin's Newly Elected Executive Board

a.. President, Andy Gussert
b.. Secretary, Kathy Kreul
c.. Treasurer, Deb Ausman
d.. Vice Presidents At Large: Mary Alsteens, John Burger, Michael
Childers, Art Foeste, Gary Hjelm, James Leppi and Christopher Romine.
e.. Senior Vice-President, Art Foeste
f.. Vice President Graduate Employees, Richard Hay
g.. Vice President Higher Education, Ray Spoto
h.. Vice President K-12, Judith Hack
i.. Vice President Paraprofessional and Related School Personnel, Pam
Campbell
j.. Vice President State Employees, Kevin Steffens

And its worse outside the USA - especially if you dont have parity
value on currency. Even ARRL handbooks are expensive - try $123.95 Aus
for "Experimental Methods in RF Design".... - its a nice way of keeping
the technologically advanced countries at the top of the heap - make
sure that books, magazines etc are too expensive for students to
buy....
my local library long ago dropped its subscription to QST, Radcom, etc
due to cost - and thats at the hobby level! - student friends at
university report the same in the professional(sp) areas.

And, sorry Win, but for those of us who DONT have the wherewithal to
buy the books we want, sometimes the net is the ONLY source of
information available. And yes, the AOE is the sort of textbook I wish
I had found 20 years ago - one volume, more use than the rest of the
bookshelf! (am saving up for my OWN copy)

You have to convince them that the power sales will justify the cost.
Most power companies STRONGLY discourage home three phase installations.

Otherwise you have to pay zillions of dollars for the upgrade.

Not only that, but they are pretty quick to remove the transformers
if the demand drops. I moved a TV transmitter a few years ago, after
the station built a new site with a new transmitter. The power company
called and wanted their three pad mounted transformers and didn't want
to replace them with smaller ones to power the other equipment at the
site, or the engineer's house at the site. We finally had to rewire the
buildings for standard 120/240 volt service and replace some motors with
single phase.

Obviously different in the US, from the UK. Here, I asked, and it was only
an installation charge for a different distribution unit. The wiring was
already present, because the 'standard' here is to run all three phases
into the building, and then have each house down the road, on the next
phase, to try to keep the loads reasonably balanced.

Best Wishes

In the US they run three phase into a subdivision, then run a single
phase down each street, alternating phases from street to street to
balance the load. Less wire to run, and keeps it simple to balance the
phases.

I found one of them on an old photocopier.
On the main board where it is connected, I have found a SED1330F with 2
mem chips(GM76C256).
Near is a quartz of 9.216Mhz
Perhaps it can help.
NB: the connector is a 14 pins

right there in black and white two feet in front of my face!!! :) )

The Front:
The New Procuct

Environment-protective
Torch For 21st Century
Rotate the box vertically 1/4 turn to find:

Features:
1 Only shake it to forward and backward while also use. So as to Make it
Generating to light up for brightness.
2. its switch system is based on advance magnetic induction
technologies. So it's long in service life and reliable in performance.
(I guess the second sentence of #2 isn't *TOO* bad...)
Advantages:
1. a tocrh is used for emergency lighting purpose. However, the
traditional battery-supplied torch may cause you a big distress because
battery will becoming ineffective and producing poliution if torch is
leaving idle for long time. The chargable torch is has problem power
leakage; or it will help you remembering to charge only at time of
needingfulness. This innovative torch is to the breakthrough in solution
to wastage and inconvenient.
2. Being self-supplying, it will serve you long and well.

Caution:
1 Never keeping it closely with the household appliances needing
magnetism from to be shielded.
2. We will not taking the any responsibility for losings and harmful
causes or any injuriousness by improper use from the result.

Next two sides repeat the same things.

The "Engrish" was almost worth the price of the darn things all by
itself :)

On the "It's five bucks, and I've got another one... Who cares if I
screw it up?" theory, I unscrewed the end to find that the innards are
encased in a second clearer plastic tube - a 5/8" long by 9/16" diameter
cylindrical magnet (*QUITE* impressively potent - I'd rate it pretty
close to the supermagnets you'd find in hard drives in the "pull a
screwdriver off it" test) inside a 1 inch long by about 11/16" coil that
appears to be "flat-wound" with what looks like 4-5 layers of
close-spaced #30 or so wire - hair-fine - I'm talking one of *MY* hairs
fine, and that's *REALLY* fine, a small circuit board with 4 1N400x type
diodes, but in the one I've opened, they're all turned so that I can't
see the last digit - Not that it matters much for the application) a
quarter-watt sized carbon-film resistor (Brown Gray Black Gold, 5 volt
.0047F electorlytic capacitor, white LED, plus two 2032 lithium coin
cells and a simple "move the slider to mash this springy bit of brass
against this other not-so-springy bit of brass" switch.

Havent' yet gotten around to fully deciphering the circuit board, but it
looks pretty simple - Diodes make a full wave bride, charging the cap
and batteries (2032s are rechargable???), switch connects LED through
resistor to cap/batteries, light comes out the end.

One of the *VERY* first things that's going to have to happen to make
this thing more than just a cutesy toy is spray-painting the body
black... With it clear, the backscatter from the bottom of the LED is
blinding. As long as it's kept "wrapped up", it actually puts out a
decent amount of light, but I'm already plotting and planning the "how"
of perhaps ripping the power section out of it and installing it in one
of the little yellow 6-LED "Streamlight" units I've got laying around -
Have to see just exactly what kind up "oomph" it can put out...

Anybody hacked one of these things in an interesting fashion yet?

Oh great... sci.electronics.* has now become the place to post a serious
question if you want to stir up a few racists and lamers spouting
stupidity and thinking it's comedy. I was under the impression that
those kind of kiddy-games were relegated to the alt.* hierarchy. My

<sigh> Ask a serious question, stir a handful of imbeciles out of the

an aperational fusion reactor?

I'll make an effort in the future to recall that these groups are now
officially intended for fart jokes and similar-level stupidity passing
as humor. Ha-ha - Get it? fart joke? passing? Gawd, I'm so clever...

Kewl, but beware you don't kill the yellow LEDs with the extra

Best I've done so far is take the lens out (better light spread) and
bungee one loosely to my bike handlebars; shake as you go!

I s'pose one could remove the LED and install a small radio circuit,
with the speaker at the business end? Hey, there's a "third world" product!

Dunno, but it teeters on the edge between "funny" and "pathetic". One
thing for sure: I can understand why there is *ABSOLUTELY NO TRACE* of a
"Who made this" statement on the box - They've *GOT* to be embarrassed
about it. "Made in China" is the closest thing to a maker's mark to be
found anywhere on either the packaging of the light itself.

Yep - The one I opened up needed the springy bit bent, and I'm also
thinking I'm going to have to take a soldering iron to it - It acts like
the soldered end has a cold joint - Mashing the end into contact with
its opposite number doesn't always make it work, but "playing with" the
soldered end while mashing the free end almost always convinces it that
the switch is closed. Remelting the solder will likely turn the trick.

And even if the rest of the unit is complete garbage, "two for five
bucks" for lithium 2032s isn't exactly "astronomical" pricing -
Especially not when even Wally-world is wanting 4+ bucks a pop for them,
and some online places are saying they'll let you have one for $5.50
plus shipping.

One of the *VERY* first things that's going to have to happen to make

I'd say "extremely distracting", but yeah. I used some self-sticky

I'm considering black electrical tape, but I'll probably go with my
"first-instinct" - "spray-paint the entire inside of the outer shell
with black Krylon."

As long as it's kept "wrapped up", it actually puts out a
decent amount of light, but I'm already plotting and planning the "how"

Kewl, but beware you don't kill the yellow LEDs with the extra

Nah, not yellow LEDs - The case of the Streamlight unit is "Day-Glo
yellow". It has 6 white LEDs mounted in the "business end", runs off of
4 AA batteries, and has to be one of the nicest LED-based lights I've
encountered so far. Now that I've figured out that 2032s are 3 volts
each (I thought they were the usual 1.5 - Guess that's what thinking
does for me) it seems reasonable that the power section of this "shake
light" thing should be able to power the Streamlight "head" without any
major trouble - If I can figure out a way to "mash the two together"
that's reasonably easy to do without completely destroying the
"handiness" of the package.
