I have to make a hardware project using a microcontroller, memory, screens, etc.

Is it possible to make an independent PDF / documents reader, which is capable of running on battery power?

Please note I don't want to use any technology which needs licensing. It must be all freeware readers, etc., and programing language can be assembly, C, Flash or any.

I have submitted proposal of PDF reader project (independent hardware). Many say it's impossible. What should I do?
