Ok, so there was this challenge on the forums to create a Morse code kinda machine in minecraft using redstone, first of all i created one that was what the challenge originally wanted, Base A to have three buttons and then the message passes down a single wire to change lights at Base B to what base A pressed. But i thought that it would be awesome to able to send message from one base to the other and then back again, ALONG THE SAME WIRE, and i think i managed it. Please take a look. I spent quite some time working out the 2 way repeater and some of the other stuff. Thanks in advanced.
