I work on cars for fun, but that might not be the most budget friendly thing to do outside of basic car maintenance. Of course, this is assuming that you or a friend has a car to work on.

What if you get an Arduino starter kit? That involves putting things together with your hands and writing code to make the hardware do cool things.
