Poor Mans DRO

After reading about the mouse guts DRO maybe some would be
interested in a low budget linear encoder.

The head burned out on an inkjet printer I had so I took it
appart to get the little motors. It had a nice 12" linear scale with
an HP quadrature detector for print head positioning. Some of the
printers go up to 2400DIP so don't just dump the old printers.
They're a gold mine of neat small parts (and full of ink from head
cleaning).
