Don,

I am unaware of a pre-built board.  I would build one from scratch if I
were going to do this.  Radio Shack has some "mini-engineering notebooks"
that contain these type of circuits.  If you have some time and
inclination and basic electronic knowledge you might be able to do this
easily.  I can give you more info if you need it.  You would have to test
any circuit first.  I have built similar circuits to tell if a VCR is on
(low power drain to slightly higher drain when on).  There are better ways
to do this today.
