and here comes some pictures of the hardware.
I'm using a 5V relay and arduino and ethernet shild. You only need to use 3 wires between this. 5V+, GND, and pin 13 ( you can use blink exempel to switch the relay on and off).
if you wan't to buy this:
5V Relay 5,40$
Arduino mega 20,50$
Ethernet shild 17,60$
Wire 3,5$
If you wan't to buy more then 3, use "BULKRATE" as cupon code when you checkout.
