Looks like it's a quad, enhancement mode MOSFET.

Sort of like 4 2N7000's.

Conceivably an interface board from some piece of kit presumably made by
Optotech Inc.

Nothing of any real value there, although those optocouplers look of
intruiging construction.




Several things intrigue me. Here's a bigger better photo:

Looks like an old motor controller board. The MC4044 is an old

phase-frequency detector, and there are counters and an op amp, plus
some things that are probably drivers (though I haven't looked them
up). That would explain the odd-shaped cutout as well.

I don't see anything in that photo that matches this description. What are
you talking about? I see a couple of diode symbols with red background
near the upper-middle center; a couple of electrolytics in the upper
left; a header connector bottom left; and in the lower right corner, if
you're talking about the PCB, rather than the keyboard it's sitting on, I
see a C-shaped blue-grey shape like a wood-worker's clamp. I even see the
VQ1006J, below the 74HC86, and above the clamp-looking thing.

But nothing matching the description, "one red and one green".

Look closely at the clamp-looking thing. There appears to be a small red
LED-like object poking towards the midline of the "clamp" (on the R10
side) and a green one on the R24 side. Don't see a silk-screened desig
for it, but I'd guess that it has to be a slotted opto detector.

You could always try shifting them on ebay though.

Audio repair guys can use those for the DC blocking cap on the output
stage of power amps.

So what are they worth to someone? $1 each?

If you have a really large quantity of PC boards, some of the parts
are worthwhile (batteries, socketed ICs like the CPU and BIOS), and the
*GOLD* on them is well worth finding a recycler that handles such
items.
Find at least three, know how many pounds (maybe better yet board
area) and get quotes.
They will deduct costs of reclaimation but usually pay spot value
(use Kitco for reference).

The landlord at the building where I sit does gold.

I could check if they're interested in that sort of thing, if you light
a fire under my ass. ;-)

I'm into bdsm, I could do that.

My mistake. Upon closer examination it was a red LED and a clear detector
on the lower right there.

It was just the angle that made it look green, it's clear. Sorry.

Some consumer electronics used standard "FP" electrolytic caps on PC
boards my drilling larger holes and using a lot of solder. They tended
to get stress cracks so a modified version was made with smaller
terminals and part of the tabs cut away.

I leave it to you to figure out what "FP" means!

OK, I give up. There are a lot of surplus dealers selling "Mallory Type FP"
capacitors, but haven't found a definition yet. Is Mallory out of
business? One of the sellers said, "made to the original Mallory spec on
original Mallory equipment..."

But I'm at a loss as to "FP", unless it's something like "footprint" or
"four-prong". Flame-proof?

Any hints?

Thanks,
Rich

Post them on EBay.

Then you gotta pay a fee if they don't sell. I should just toss them all.

If they don't sell, the fee is tiny.

If you list them at a high price to start with, it's about $5 US to
try.

BUT, if you list them at a penny and don't ask for any frills, it's a
few thin dimes.

Plus a percentage (up to 5.25%) of the selling price if they sell.

Compares favorably with doing a garage sale in terms of time and yield
if the stuff can be packed/shipped easily.

Well, it's not that simple. The IR from the LED is short wavelength
IR, about 800 nanometers. The IR that the PIR motion sensor senses is
long wave IR, maybe 7000 to 15000 nanometers. So it's like pointing a
VHF transmitter at an AM radio and expecting it to receive something.
Ain't gonna happen.

However I could put a spark coil in place of the LED and light a gas
jet or something. That should do it. Probably burn the place down
too! :-o

How about a nichrome based emitter set at 98.6 deg F, and a slow
moving fan between the heater and the lamp sensor.

I'm not sure what the fan is supposed to do. There are no convection
currents coming off a body that low a temp.

But you have a good point. Some of the motion sensors use ultrasonic
doppler to sense the motion. They have a transducer driven at a freq
controlled by a ceramic resonator. Any returning echoes are compared to
this reference, so movement is sensed, even if it's the air moving. And
it says in the sheet packed with the sensor that the sensor should be
installed at least 6 feet from any air duct. The contractor dorks who
installed them in our bldg installed the one in my room about 3 feet
from the air duct. And yeah, it would never turn off.

But these are not PIR motion sensors.

That is why you are advised to set your line length BELOW 72

I tend to use 68, because any text that gets more than four >s isn't
usually worth the bother.

In the options I can find fonts and stationery, business cards, but no
line length.

The only thing I can think of is to increase the point size of the
courier font. That way the letters are bigger and take up more of the
line, so there are fewer per line.

Maybe I should start doing like some others do, and post with variable
pitch fonts. That way the number of letters per line will be much
greater and the first time they get broken, they will be split right in
half. ;-P
