[TriLUG] remote power on/off device

[Michael Thompson]

I paid $49.95, and it probably took about 3 - 4 hours to build and test,
IIRC its an extra $10 assembled.  There are also some cool RF
transmitters with 4 hi|low outputs that would interface nice with the
unit so you could send up to 8 (I think) different signals to the pc
with it.

There is a .pdf file at the link with the schematics for the relay
controller and the instructions for use, should give you many ideas... 
:)
