eng.nema you can get the idea yourself, we're like you, our minds have not the dozen of GP ideas as you think, we can answer you in design question, programming task, and so on..
try to get some ideas and we can recommend some of them.
me to I was studying Computer Science in Egypt, the professors don't help in finding a project idea. you MUST do that on your own, because that's your project you should develop what you feel may make a difference!
If you are CS student, try to keep hardware a way for some reasons (time, team members, ...) you can work in software idea absolutely software.
if you're convinced, so tell me which computer field you're interested in?!
