stepper construction

[Jon Kirwan]

A few wooden yoyos, some scrap metal cut to size and a few magnets and a
few electro magnets and have fun.

I'm a little past that.

My last homemade one was a magnet, a nail, some wire and some brass
strips, around 60 years ago ;-)

I think we've all built ourselves a motor like that at least
once in our lives. I even built an earphone once, too, that
worked tolerably well. Of course, I'm on about something else
now.
