For devices that need drivers, best bet is normally to see if a commonly
available part with a break out board (to avoid having to design and build
circuit boards!) is not yet supported.  Works best when it's something
you are interested in.

Other alternatives that can be good places to learn are around modernising or
debugging existing drivers.  Either get the hardware if possible, or
another useful skill to learn is how to emulate that hardware.
Personally I tend to do that on QEMU but that's because I'm more familiar
with that than other alternatives. 

Other than mechanical changes where we can easily see there is no functional
affect I wouldn't advise trying to work on drivers unless you have good
emulation to test against.  Doing emulation for a device that isn't currently
supported is also unwise because it's hard to know if it is right without
getting that thoroughly reviewed. As such it tends to be most helpful when
you can assume the existing code works, test the emulation using that and
then test your refactors and updates.
