It's a good board that one, although you should buy it as a kit for added fun. The linux drivers work well too.
Ahh.. that's all good to know, thanks guys.
I did notice one in kit form at our local shop, but there was
too little tech info for me to decide whether or not it would
be easily usable on Linux.
It is perhaps a tad expensive and large for one-of uses,
but fun to play with otherwise.
Along the same vein, here is an
electronic replacementfor the relay board I used.
And here is a nice, cheap real-world
relay interface kitthat works over serial (or USB if one adds a USB-serial converter).
EDIT: And, ooooh.. remote control of stuff
via the telephone,
and reasonably priced, too. I can't think of how many times
I've wanted something like this, to reset or power-on a box
while I've been far far away..
