No, my favorite one was the "Blood for Oil" screamers.

Since we aren't getting the oil and our prices are now on the rise the
same group is now claiming that it was all a plot to raise oil prices so
"they" could reap huge profits. See how no matter what happens there is
still something to bitch about and it is always "their" fault. Sort of
like the Y2K hysteria.

I don't know about that. Solar PV can be used in any size from digital

The point is not whether or not they can be used, but whether or not
they can be used economically and profitably.

Oh, if that was the point then it's already been decided. Right now,
solar PV is not economical or profitable except in niche applications
not connected to the grid. Tomorrow... who knows? It does seem to be
getting cheaper all the time.

This, of course, has nothing to do with the question of "Is the
profitable use of solar PV limited to big mega-corporations?"
I like it that the Dutch solar car went cross Australia in 3 days or so

with an average of over 100 km/h last year.
Now here is a very sensible application in a suitable 'solar' climate.
Those photocells were the same as used by the European Space Agency.
I would love to have a few square meters of those to play with.

Well, Jim, my favorite is the fact the oil companies are reaping super
profits and able to claim it has something to do with a minor adjustment in
the price of foreign oil. Certainly nothing they are doing to adjust their
company profits. Really! Ignore the man behind the curtain. Yeah, sure!

Well, these are point contact transistors, old outdated technology.
That makes them rare, and thus worth a lot to collectors. Or worth a
lot to someone anyway, maybe just someone who wants to resell them for a
profit.

At one time, I thought about purchasing some old point contact transistors
to play with -- but the benefit would have been nil. There is some
temptation, but (to me), there is more challenge in playing with
more forward looking endeavors.

However, there is still some temptation to play with some point
contacts (before my time), or get some 2n525s (AFAIR, one of the better
components when my hobby started) to remember the 'good old days.'

Yeah, I remember. GE made those, and promoted them for such things as
audio preamps. Then Motorola came out with the 2N1192 series, and
National or Fairchild with the jellybean TO-106 packages such as 2N5233,
etc. And GE had the 2N3391A series, etc. Ah, the 1960s.. Problem was
that I was a starving student w/o money to buy any of that stuff. Now I
can afford it, but I don't have the time or eyesight to do as much as
when I was young. Damn, always something creating a stumbling block..

Then, reality grabs me again, and instead, I go back to work on
my automatic RF wideband impedance matching program (interfaces
directly or indirectly with spice like programs) for my electronics
hobby, or build another UHF TV preamp concept...

I guess for 'hobby' applications, it really doesn't make much difference
if we are playing with near-state-of-the art, antique or ancient
electronics technology -- the goal is to enjoy the hobby itself!!! .

And they say that the smell of hot solder has toxic lead in it. I guess
I'll end up buried in a toxic waste dump. They'll analyze my hair and
GASP! and ship me off the the high level nuclear waste facility!

These are point contact rather than junction transistors. Transistor
collectors value them because they are rare. The 2N110 is a point

industrial and millitary equipment.

Older point contact units like in this auction

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3800110452

are quite a bit rarer and chances are there are not many around. If
you think how important the semiconductor is to modern society, I
think it is a very overlooked collectible as far as collectibles go.
Take a look at what an old edison light bulb will go for now to get an
idea. You have also got to remember that most of the transistors in
the auction above were hand assembled in the lab under a microscope.
They were also VERY expensive in their time. Transistors like the
CK722 and to a lesser extent the 2N107 have a lot of nostalgic value
as the first transistor someone ever experimented with or what started
many a career as an enginneer in later life. Bottom line..people
collect everything.

Take a look at the excellent website here for more transistor history
and lots of pictures.

http://users.arczip.com/rmcgarra1/

Now go root in your junkbox!

I acquired 5 more CK722s last year, along with the four or five I
already had. Looks like I'll be able to retire on the proceeds. ;-)

I like that answer. I tried photographing the component using a canon
S45 and my 35mm diopters(couldn't find the magifying glass and a loupe
would have interfered with the flash), but the laws of physics aren't
on my side on this one. As you get closer to the component, the depth
of field gets very, very thin. The automatic focus was a complete
crap shoot as to where it would wind up and manually focusing wasn't
really any easier.

I could get good images of the other nearby components and their
markings, but the marking on this transistor was particularly faint
which made it even more challenging.

Thanks to everyone for the help - I'm off to go find the datasheet.

Two questions ...

1. I'm aware that when running an LED on a DC power source, the
polarity must be observed or the LED won't light. But when the rated
voltage of the LED is less than the source voltage and a resistor has
to be used, does it make any difference whether the resistor is
attached to the anode side of the LED or the cathode side?

2. The AC adapter for my "itty-bitty booklight" is rated "4.8V 500mA",
but it's actually 4.8 volts *AC*, not DC. I hooked up an LED (with a
resistor on the "+" side of the LED) to the socket and found that it
"works". But just because it "lights up" doesn't mean that it's
"right" (in other words, if you overload an LED by running it on a
higher voltage, it'll "light up" too, but you'll be damaging it). So
the question is, is it OK to run an LED on an AC power source? and if
"yes", is it sufficient to have one resistor or do you have to have
one on either side of the LED?

In series is all that matters. Either side is fine.

LEDS don't have much reverse voltage capability. Your 4.8 volt AC
supply will produce more than 4.8 volts when it is unloaded. 10 or 20
percent more. It also produces a sine wave that peaks at 1.414 times
as high a voltage in each direction than the effective voltage you
read with your meter. so that LED may have to withstand something
like 7 to 9 volts peak during the half cycle that it is blocking the
current. Some LEDs will handle that and some will not.

You may want to add components to lower this high reverse voltage.
Some possibilities are, a series diode that will prevent any
significant reverse current, an anti parallel diode that will conduct
enough reverse current that the series resistor will waste all the
reverse voltage, both of the above, another LED connected anti
parallel to both do the job of the second diode mentioned, and also
produce extra light, a bridge diode between the AC supply and the LED
resistor combination to convert the AC to rectified DC.

By the way, the transformer in the wall wart doesn't like DC loads
much, either. It will run warmer than it normally would for the same
output power drawn from both half cycles.

Sourcing INTO the power grid is also supported in Arizona. Apparently
there are a few customers here who produce more than their own
consumption and get PAID every month. (Not difficult at all if you
own at least an acre of property.)

How do they regulate the current they draw? I mean since the capacity
will vary.

If you Google for LMT324 you'll soon discover that it is not a typo; it's a

I have been an electronic technician for over 40 years, and never

Line Output Transformer, pronounced "loptie".

It's what monitor techies in the UK call a flyback transformer.
Strictly speaking, I think the word 'flyback' is more correct, since
these transformers operate on the flyback principle.

The term 'Line output' comes from the earlier days of TV sets, when a
conventional transformer was used to boost the horiz pulse to about 9kV,
which was then amplified by a tripler module to produce the final anode
voltage.
