Re: mouse encoder?

Tim Goldstein: "Non-optical mice (the type with a ball) use 2
quadrature optical encoders to read the movement. Very low
resolution, but certainly an inexpensive source for an encoder to
play with and learn.

Weyland: "Reeeeeeeeeeeeeeeally. No shit. Just when you thought you
knew everything... (:>)"

One more source of encoders. I have in front of me 2 encoders (plus 2
18" guide shafts and bearings) cannabalised from 2 Oki printers. The
disc is 40mm (1.5") diameter with an estimated 100 slits and a
GA1A7OR Sharp AO photocell?. Any Junkyard War Veteran can give any
hints as to what kind of contraptions I can make with these?
