I'm thinking of doing some hobby electronics design, to augment my already busy professional schedule (I like punishment).
The gizmo I'm thinking of building would be used out in the field, by folks who wouldn't always have laptops or wouldn't want to spring for them.
My preference would be to build the gizmo with a USB interface, set up as a modem so that I could just talk to it with a terminal program. But I can see some potential users wanting to do this with a separate terminal.
So -- is there anything already made that consists of nothing more than a USB host with a terminal, and is reasonably cheap? Preferably it would be something that's already sold, that I could just point people to, and preferably it'd retail for less than $100. Or should I be thinking of either not serving that population (since I mostly want to make these for me), or making the thing spit out old-style asynchronous serial?
Suggestions welcome.
