</div></blockquote><div><br>1. i have ethernet. i do not have rs232. that's what i have.<br>2. rs232 specs say it is for 15meters (which is too short anyway)<br>3. only one computer can connect to an rs232. so i need to set up a server for the rs232 <-> ethernet, which i do not want to.<br>

i want to control the warehouse external lights from the house.<br><br>I thought of buying an X10 light switch, but it seems that each consts around 50$, which is expensive<br>
so my other option is a computer i can control (prefferably a linux box, somthing like nslu2).<br><br>so:<br>1. anybody knows of a cheap place to buy X10 stuff (or somthing similiar) ?<br>2. what is the cheepest "computer" (doesn't have to be a full computer, an avr with ethernet and gpio will do) ?<br>
