Old computer mice are being abandoned in droves. They're tossed out because of dirt, obsolescence, or for being entirely too beige. Anyone who has a computer usually has more than one mouse and you can get them for pennies, if not free just for asking. Fortunately for the discriminating (read: cheap) hacker, these little widgets are chock-full of project parts. Today's How-To will dissect a computer mouse, extract the useful parts, and give some ideas about how to use them.
Here we have a standard PS2 mouse; a USB mouse will look pretty much the same. We'll talk about optical mice later on.
Lets open it up. First, take out the mouse ball. Then there will be one or more screws on the bottom side that need to come out. Screws are sometimes hidden under the rubber pads.
