I'm trying to get into hardware hacking as a hobby. I'm trying to find some good information on the reverse engineering bit. Does anyone have any good directions or sources of information? Primarily I'm concerned with signal tracing. How can I track what bytes are sent accross a line?
I'm wanting to solder some wires into a circuit and attach to a db9 connector that I can send some signals across to simulate what the button push does. I'm hacking my sprinkler system. Just having fun while voiding my warranty.
