Ah ha, here’s a good X10 Solution for your Christmas lights. What is X10? It’s a communication
via your existing AC power lines. Well this is more complicated the 5 minutes version we made
the other day but still good info on X10 Protocol in general. You still have to build it so it’s not really
plug-N-play but a great solution if you have some knowledge of electronics.
Next time we will have to hack the 5 minute version to work with the X10 devices which should be simple
and a matter of adding serial to X10 converter.
