We just blew the linear encoder on our hydralic press at work. A new
one with 40" of travel is fairly expensive and I got to wondering if
you could use an optical computer mouse to measure distance traveled.

The idea is to mount the mouse to the base of the press and have a
piece of aluminum flatbar attached to the ram. The bar would pass in
front of the optical sensor on the mouse and a dedicated PC would
display the distance traveled.

Does anyone know if software to do this exists?
Failing that, is there any reason why Visual Basic shouldn't be able
to do this if I were to dig out my old copy and install it?

I deal with glass scales all the time, if you're looking for precision then
even if you could get the mouse to work in that manner your accuracy would
not be there. If you're in Ontario the ministry would also take issue with a
device modified in that manner that was not OEM to the machine, should there
ever be an injury involving that machine. What make is the original scale? I
have found exact replacement scales for Heidehain scales that were half the
price from a guy in Chicago that deals with Fagor scales.
