Has anyone every hacked a computer mouse to harvest the two optos in there for limit/home switches? I have no problem interfacing a plain ole switch to my HCNC, but don't know what extra electronics would be required for an opto. Has anyone done this? Got a schematic? Thanks.

PS: I realize that dust can be a problem with opto switches out in the open so I have a solution to that but I don't want to cloud this discussion with that issue.
