…is there an integrated circuit available that would encapsulate this
project?:

Recently I found a components trading website www.koobid.com, they ask
you to post stock with PRICE, and all your search result are really
with PRICE. How Possible ? But maybe a good idea, at least I can get a
part price for reference when search a part, do not need to pick up
the phone. And I do think some traders could not give their "so-Said"
thousands of STOCK a price.

Hi
Can anyone help?
I am looking for carbon resistors – in Johannesburg.
spec: 2.2 mega ohm, 2 watt – 450 needed.

I’m trying to identify some decoupling capacitors, probably ceramic.
They’re orangish red, about 8 x 6 x 1mm  axial leaded.
They are labelled on the top, that is the 8 x 1mm curved face
away from the leads:-

104
YME

To the left of this is what I take to be the trade mark which
is a narrow slanted V which is as large as the two lines of
lettering above.
The left arm of the V is about 5 degrees clockwise from vertical
while the right arm is about 10 degrees so the whole V points
down to the left.

I assume 104 means 100nF as it usually does.  What does YME
mean?

I’m asking because these caps were provided for a fairly exacting
operation, namely decoupling photomultiplier dynodes in cryogenic
conditions.   They’ll be run at about 200V and , er, -190C.
They look awfully small for 100nF/300V and I have my suspicions
about their temperature coefficients.

Hi Guys

I am currently working out of UK for 3 months and am in desperate need
of a Accelerometer  for a team that working out of India. They have
asked me for help in procuring the same.

Its a amateur project and almost any kind of cheap Accelerometer
would do. Can you guys give tips on getting it here (Southampton,UK)
or back in India

Thanks in advance

Dear all,

I was wondering if any of you knows about commercial connectivity
solutions that enables to make an electric connection between an
electronics package and a flexprint. The requirements are:
– mechanical robust and stable
– solderless and glueless
– electronics should be reusable, i.e. the connector can be opened and
closed many times
– 2 electrical contact are needed
– not bulky

I was personally thinking about some conductive velcro or a clamp that
punches some pins through the flexible substrate film.

Any kind of suggestions, links, etc. are welcome!

Thx,
David

I am trying to make a pulse generator that will generate pulses as
short as 1 ns, with voltages around 1V.  It would be triggered by an
external signal.  I am wondering whether anyone makes a single chip
solution for this type of thing, or if someone knows a communications
IC that could be easily modified to do this?  And it would be great if
it came with an evaluation board, though I realize I am reaching on
that point.  (Still, unless you enjoy torture, soldering surface mount
components is something I like to avoid.)

As I’ve searched on the net, most DIY pulse generator circuits involve
avalanche circuits which seem to require relatively high voltages and
are a little unstable.  Linear has a circuit that uses comparators
with an AND gate to produce a pulse, and that seems to be pretty
workable. I’ve also thought it wouldn’t be that hard to combine an
inverter with an AND gate and a delay line IC to produce an output
pulse, provided the transitions didn’t excessively widen the pulse.

I find many listings of commercial part suppliers for a 125C0088
(8-pin DIP), but not a data sheet in sight. It’s part of an obsolete
light control actuated by a garage door opener remote. Other IC’s in
the unit are a 125C86 (16-DIP) and a 125C0042 (8-DIP). All have the
National Semiconductor logo and are involved with decoding the input
from the RF remote. The unit was built circa 1992.

Any ideas what this critter is?
