poor man's IO?
I'm aware of that one can use a gamepad or joystick to provide a "poor man's I/O interface" for input signals. But how about output relay closures? What's available with a USB interface that would lend itself to being used for controlling switches, presumably with external relays? I'm thinking of using something like this for handling stuff like the 12v signalling question posed in another thread. I'm not insisting on taking the cheap way out but would prefer to find something in the sub-$50 range. Perhaps with at least 8 outputs?
Suggestions?
