Thanks Neil, that's a very interesting looking device.

They have various programming interfaces to it and it works with
more OS's than just Windows.


Indeed, that's always a good option.

You'll need to do some filtering (it's a 5v(?) device) but I don't
think that's too much of a problem.


Yeah, not to much trouble. I've got AC to the boat during the winter. I
could step down the onboard 12vdc. But then again I may want to use
something like X-10 (gasp!) to control power to it.


Sorry probably the wrong term what I meant is the you'll need to bring
down the 12v to either 5v or 3.3v (I'm not sure which voltage) using
and op-amp. Or if it's more digital (0v or 12v) then maybe a
transistor or a zener. Basically you need some simple electronics to
bring it down to acceptable levels so the device can deal with them.
