Great advice from mlm Just rip off the rubber wheel cover! Don't do this!! My wheel does not work at all now! This looks nothing like my Microsoft mouse. Very helpful. For me, the first screw is a T9 Torx, not T8. Load more comments. Single Step Full Guide. Microsoft Wheel Mouse Optical 1.

Member-Contributed Guide An awesome member of our community made this guide. Introduction I've owned two of these mice, getting several years hard use from each before experiencing issues with intermittent right-clicks or false clicks while scrolling.

Introduction For this teardown you should have a small phillips screwdriver a flathead screwdriver or some other kind of prying device. Step 1 Remove Battery. Add a comment. USB plugs are a useful source of power for custom electronics, so this cable, with little modification, may be one of the more useful bits in the mouse. Stripped of its outer insulation and separated into individual wires, we have a source of particularly flexible stranded insulated wire, potentially useful for all sorts of "wearable" electronics.
Some components are more easily de-soldered from a PCB than others. Through-hole parts with three pins or less are pretty easy to remove using solder-wick, for example. In the mouse wheel, which is also optical, there's a two lead part that is an infrared LED, and a four-lead part that is dual photo-transistor or perhaps more complex circuit that outputs signals sufficiently complex for the microcontroller to tell which way a slotted wheel turned with the mouse wheel is turning.
This is all on a nice separate board; with a bit of mechanical skill you might be able to use the wheel separately from the rest of the mouse. A three pin resonator replaces a crystal and two caps in most microcontroller circuits. The older version has two 2-pin resonators somewhat less useful IMO.
That leaves the more difficult components to remove. SMT components and things with lots of pins. You can stop at this point, unless there's something you really want. The optical sensor is rumored to be usable as a low resolution camera 32x32 pixels? The USB microcontroller on the older mouse looks to be a somewhat standard Cypress part, but is probably not reprogrammable.
The clear-packaged "Mouse on a Chip" is rather pretty as chips go. It might make interesting jewelery. I managed to get it off the board by heating the whole thing over a gas flame on the reverse side of the board till the whole thing was smoldering and the solder was melted, and then THWACKing on a moderately hard surface.
The house smelled bad for a week, in spite the exhaust fan; this sort of thing should probably be done outside if you're going to do it. Reply 3 years ago. Reply 4 years ago.
Question 3 years ago on Introduction. Hey DOC: I have also taken apart some wired optical mice for fun. I am guessing that i only need to keep 2 lines active, and can defeat all the others. While reading the steps I was thinking that this would be a great Maker Space item.
