I must congratulate you on a nicely written Arduino application. As
you demonstrate,
it's not critical what hardware gets used.
The feedback/hysteresis loop in the program is nicely documented. It
begs to be used.

Your design is much like mine. I was going to use tube stock rather
than build it. The bearings are remarkably cheep, though. I found them
for $$7bux.

>From a simplicity point of view, building it from bicycle parts is as
common as you can get.

Have fun,
