    I want to design N number circuit, Two transmitter/receiver are
    matched, No other should be able contact this dedicated pair, N number
    should be self identifyable/programmed.
    Please give circuit/parts and other details.
    Thanks

    Both the transmitter will have:

    1 PIC,
    1 LM555
    1 LM7805
    5 0.1uF NP0 capacitors
    3 47uF, 35V capacitors
    16 1K 1/4 W resistors
    16 100K 1/4W resistors
    63' #26 hookup wire
    2 24 pin x 0.3" DIP sockets

    Why should anyone do that? YOU are going to "design" it........ So design
    it.

    What is being transmitted? (data, button pushes, prescence)?

    Over what medium? Hardwire, optcal, RF, sound?

    Is a micro an option? Ready to go IC? Discretes?

    Will it need field programmable (dip-switches, eeprom, computer
    programming, handheld programmer?

    How many unique units?

    Is there any security concerns? (as in possible cloning or monitoring of
    transmitter unist?

    Well no matter what it is, I'm *sure* it can be done with a PIC.
