Looking for suggestions on simple circuit w/out using microprocessor to
drive multiple LEDs in a random blinking pattern.  The objective is to
emulate a "jar full of fireflies".
Numerous Google searches have yielded some interesting things, but nothing

       Does anyone have or know where I could get a data sheet for this NEC
display driver IC.
                    Thanks  John Ely.

Does anyone have an old ASR-33 teletype that they'd like to sell?
Please reply via email.

I have a nice electromagnet that I got on eBay (
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200045827548 ).  I'd
like to determine it's maximum current for 100% duty cycle.  My plan is
 to apply a small voltage (say 1 volt), let it reach steady state

No mention of how to remove them but I saw reference to the critters having
proper name thysanoptera that are for some reason ,unknown as yet, attracted
in there.

Would someone know if the proposed new network has equal advantages
for city slickers as well as the country bumkins?,or is it really only a
predictable move by the Telstra CEO to get golden handshakes from
the equipment manufacturers?

could some one please help me with a VHDL program for a traffic light
system.
thank you

Can someone tell me whether Wombats live only in Australia,
or also on other continents?
Apart from zoos, of course.
We all know that Wombats are to be found in Zoos.

I have 2 crystals rated at 3.57 MHz  (for driving video)
One is 2 pin, and the other is a 4 pin.   I have the 4 pin working, but not
the 2 pin -
I am looking for info on how to substitute a 2 pin in place of a 4 pin.

where can I find information about the output format of the various
simulation tools like e.g. spice.

Ladies and Gents,
A collegue of mine in our workshops needs a long length of 0.5mm
enamelled copper transformer wire, but really long (approximately 2km
single length). Does anyone know where in the UK this can be purchased?

I have purchased a set of battery powered kitchen scales and I would like to
convert the readout from LCD to LED -  if someone in/near Melbourne and
would like to consider this and another small job, I'd love to hear from you
the other job requires me to be able to sense a low ...

could some one help me please with the program of a traffic light using
VHDL.
thank you

Does anyone know what type of connector this is?

Standard DB9 to the right, unknown connector to the left. Note the
diagonal keys in the plastic mould for each pin, with the top right
