you could take an ordinary clock apart, and piece it back together into a metal box, and make sure it would in no way look like a bomb and then say you "invented" it.
Short of that, if you are musician, there are tons of projects for guitar for example. If a car nut, mods to cars are useful and fun. If into planes, you can build a model flying kit.
Gotta have interests to have the need to "do" things.
