[mdlug] Relay controller

[Michael ORourke]

I'm looking for a relay controller interface for an old laptop, could be USB or serial port, and some Linux based software to interface with it.
I thought about getting some X10 appliance modules, but then I would need a X10 firecracker (serial interface) and a X10 wireless transceiver.  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.
Does anyone have any recommendations or experience with interfacing relay boards to a PC/Laptop?
