I have a lot of steppers and other mechanical parts collected over the
years, have a lot of ideas what to do wit them, but actually seems
like nothing will ever be built.
You can play with MCU's or plain electronics just about everywhere you
can put a laptop, but mechanical stuff requires much more time,
workshop environment, or at least dedicated space.
So it's not just a problem for kids.

BTW, some of steppers I have are quite special. Their axles have
internal M5 threads, so they can actually run on a stationary
leadscrew, could be very useful for a small cnc. No way to eliminate
backlash, though.
Originally those were tuning resonant chambers in NOKIA 900MHz GSM
base station modules. Actually moving a copper plate in an aluminium
box.
