This is a difficult request to answer, as most of didn't take your course, so we don't know what you have learned. For a 'Electronic Design' project, I'd guess you would be required to write up a proposal, design a circuit, make a PCB, assemble and test, troubleshoot and revise, and write a project summary. How many weeks do you have left before it needs to be turned in?
Obviously, your project must unique, not something your instructor has seen many times over the years. Might as well just by a kit from Radio Shack.
Your instructor is well aware of the course content and the quality of your efforts, so you would need to do something within your capacity, which of course doesn't look too impressive so far. We could only guess at what you cando, what your instructor expects, and what your classmates are working on.
There are quite a few people here who can help, but you need to start this on your own. We can look at a schematic, but we can't look into your life. While you are sitting class, what sort of things are you thinking about building? While I was in school, I use to get inspired all the time by something my instructor was discussing, and he thought I use to take a lot of notes...
