I am looking for the front panel knobs for the HP3582A Spectrum Analyzer. I
would also consider an old non-working one for a parts source.

I recently came across a tiny spycam, it measures 12mm by 10mm and has
12 contact pads on the base of the sensor. I assume it is missing an
interface board.
I have searched all the chip manufacturer's logo references without

Hello, I am looking for a fast optical shutter (probably LCD).
It must switch between (almost) transparent and black at a frequency of
about 100 Hz, with switching times of about 1 ms. The needed area is

I am searching the obsolete A3951SB  motor driver chip
Manufacturer Allegro.
I there an source to buy it, want about 10 or 15
Thanks

8051 Development Board / 89C51 / MCS51 / 8052
After searching for ages for an 8051 board I can develop stuff on I
finally gave up and made my own. Its not like I wanted anything really
advanced, just easy to use and easy to debug...

    --Looking for a source for one of those big red mushroom kill
switches, the kind that lock when smacked. A twist in one direction
unlocks the switch. Does anyone have a proper name for these to search on,
or better yet a source?

take a very simple LC oscillator like this:

I need to replace a resistor and can't seem to figure out the value. The
body color is gray and the bands are green, blue, gold, gold, white. I
googled for precision resistor color codes, but had no luck. Any ideas?

I'm designing a solid state HDD* (Think USB keydrive, but IDE) and I
need to find some flash memory chips to work with. Does anyone know of
a good chip for this type of application? They will need to handle many
writes (10,000 or more), hold data with no power (or maybe with a

The last of Lou Garner's estate.  Lots of old transistors and a few
other things.

Someone should come up with a 'football pool' chart and let people take

this is the first time i send a message on this news group, buy the way i'd
like to know :
if it's possible to remote controlling XP, buy sending intentional EMI using
computer comunication protocol.

Hey everyone!
I've got this random LCD screen that I'd like to use in a project but I
can't find out any useful information on it.  The only markings on it
are:

Just curious how these two chips differ - can a 75ALS193J be used in
place of a 74LS193N?
Uses will vary, but generally the circuit boards that I would use them
on are about 20 years old.

Can anyone tell me a IR sensor or a logic which gives an output voltage
propotional to the intensity of the incident radiation.
My transmitter is a 940nm IR LED. And i have tried many sensors
like TSOP 78xx , but here it detects the radiation. The output
