silencery: I appreciate the thought, but two things keep me from using a mouse wheel+girder (or the like):
- Its Windows only (no MS operating systems allowed here, folks). I follow the *NIX philosophy of "one tool for one job" - a daemon to monitor & process outputs from the encoder, another for the IR remote, another for the GPS, etc.
- I have in my mind the way I want this project to look+function, and a hacked-up mouse wheel doesn't fit into the plan. Plus, if all I did was assemble *everything* from off-the-shelf components without putting a little of my own blood, sweat, and tears into the mix, I'd be no better than the Teutuls (the OCC folks).
That's not to say that using the mouse wheel+girder isn't a good option - its just not for me.
