Pager Gear Motor (Really tiny!)
These little gear motors measure 20.8 x 29.0 x 25.4mm
(0.82 x 1.14 x 1.00) and weigh in at 4.7g (0.17oz).
The square output shaft measures 3.56mm (0.14) per side
and the leads measure 5cm (1.95) long.
They're a bit funky in that they're not continuous rotation by default.
They have a selfcentering spring so applying DC power will result in
a 60 degree swing in one direction.
Reversing power swings the output arm 60 degrees the other way.
Remove the selfcentering spring and clipping the stops and away you go!
