You don't even tell us what field you are studying!
You already been given the criteria/guidelines of what to propose by your professor, why don't you think up of a dozen project ideas, crazy or not doesn't matter, and post here. You can think, can you?
All of us here is more than willing to offfer you our opinions about the pros and cons of individual project ideas, and resources about varies circuit design and components.
You then reads what were posted and makes up your own judgement of which project to take on.
