[ned] received a free X10 RF remote. He popped it open to discover that the device is actually based on a PIC. By replacing the PIC with his own he’s able to issue any X10 command using the remote to any device in the system. He did spend a lot of time with a logic analyzer to try and figure out the protocol, but later found some good reference links. He hopes this will make it easier to connect his PIC projects to the X10 system since this remote doesn’t have to be plugged into the wall like the X10 serial interfaces.
