user8013: To be able to switch 220 volt stuff on and off using arduino, I need a relay (I assume). Is there really no nice extention cable with built in relay so you dont need to cut and connect high voltage.
I imagine a Power strip With a simple input port that can be controlled from the andruino, just like a relay board. When I Google this I get a lot of USB controlled and remote controlled, but none that works with an andruino project.

user2881: PowerSwitch Tail is what you are looking for.
