Hello, I'm doing some experiments about serial communication using the mains. As you can understand, I'm wanting to do something similar to X10, but with my own protocol. Someone here can point me to places on the web with squematics and sugestions of simple circuits that can inject a signal like a 20KHz sine wave on the mains that could be received by another device?
