[mdlug] Relay controller

[Michael ORourke]

Dan,

Good suggestion.  Initially I had planned on using an old laptop (because I have one handy), but a raspberry pi board would probably work fine too.  For my project, I need it to monitor 2 temperature sensors and control 2 relays.  I guess I'll do some more research on interfacing relays and sensors with the raspberry pi.

Thanks,
Mike

Searching on Ebay, I found all the X10 parts for around $60.  But then I did some more searching and found several sellers that have just the relay boards.  The project I'm thinking of would probably be well suited for a dual relay board.
