I am looking for the simplest collection of logic chips that would
produce the sequence 001, 010, 100, 001, 010, 100, ...
I know that a PIC could be programemd to do this.
Any help would be greatly appreciated.  Thanks

Hey guys,
               I was thinking of a new concept whereby we could
square the amount of information stored in a bit. Currently, the
information stored in a bit is whether the bit is on or off. To put it

Is there a web site that will cross reference chip numbers?  I have
some older designs I would like to build, but the chips they list are
no longer made.  Any help will be helpfull.
Thank you,

I would like to use a dialer chip the NTE1691. Can some tell me how to
use the RC pin, There a three pins used ar reference frequency, The
datasheet does not say how to hook them up (RC), and also it do not
talk about the output frequencies for dialing.

I have an application where I'm driving a device with 5 volts DC.
From time to time it is necessary to give it a short pulse of 24 Vdc
then revert back to 5V.
I have a power supply that has both 5V and 24V outputs.  Can I just

Hai!
   Kindly forward me anything about blue ray please.

If I change the tank circuit components (reduce the capacitance and
inductance) and change the transistors to appropriate VHF ones, will I
be able to pick up ATC (Air Traffic Conversations) using this
circuit ?

       Send me the details about microprocessor 8086.
       Expecting reply!!!!

Here is the problem.  A client company has about 100 pieces of equipment
that they want to track when and how long they are down for service.
The equipment can be a few hundred feet from the nearest computer.  The
requirement is for one computer to track every piece of equipment. ...

I have a stepper motor from Airpax, modle C82710 that has 6 wires
connected to 2 windings with a center tap. It's rated at 12 volts, 36
ohms from center tap to the end of the winding, and 7.5 degrees per
step.

    Sorry for such a simple question, but I've got a few 120mm
240V .125A  (?30W) axial fans like a bigger version of the case
cooling fans in a computer.
I've set one up in a box with a large truck air filter so I can run it

I am a total rookie when working with circuits, but I have built a kit
set transonic proximity sensor. I'll explain my use at the end.
Essentially what it does is turn on an LED when an object gets near to
the sensors. I have extended the kit with another kit to add relay

What would happen if you tried to jump start a 6V battery with another
12V battery?
