I was thinking.. it would be very convenient to have general control utility to switch ON or OFF various things in observatory (power, lights, filters.. you name it)..
I have couple of National Instruments USB-6501 modules, they are ideal for that purpose from h/w point of view.. but I don't have any drivers (I know they are part of NI packages, but the price for all that is out of amateur's pocket.
Does anyone knows of alternative solutions for application that can be used to control 6501?
Also, how about USB-> parallel adapter?
Or this Arduino relay board :
