Not sure what your field is, but the Jaxy of All Trades blog is currently running a series on electronics projects for beginners. She is finishing up some introductory stuff on components right now, but will soon delve into projects. You may be interested in seeing what she's doing to gain ideas for your own project.
Please provide much more information as we have absolutely no idea what field of engineering you are in and what level of qualification the project is for. Is a model bridge made of used wooden ice block sticks and string suitable, how about a SCADA system of a simulated working nuclear reactor.
Is this even for school or a personal or job project?
