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 Achyut
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.
