I have to design, test and build a project for my final year of my HND Electrical & Electronic engineering course, and I am unsure of what I will do. I would appreciate any ideas, no matter how difficult or easy they are, these will just be ideas which I might use to adapt into my own project. What would be something good and useful to build? Hopefully this thread will also help other people in the future with similar problems, or might just give you an idea for something useful for you to build as a hobby. I think I will be using a PIC microcontroller for my project due to some course requirements, however, I don't need technical information, just a few ideas. Thank you.
