Making That Optical Mouse Work


Introduction: Making That Optical Mouse Work

Few days ago I was facing a deadline on a project and my computer mouse started acting up. It would skip or lagg etc. It was a real pain to get it to move where I wanted and different mouse pads didn't change a thing. Didn't have spare mouse, one used by my wife was too small for my hand and visiting nearest computer store would take an hour which I didn't have at the moment.

Step 1: Tackle

Next thing I tried was to clean it up. This made no significant difference so I opened it up (had small Phillips screw driver at hand). Cleaned it inside out, assembled and still no difference. I was about to get out and buy new one when I looked a bit closer at the bottom side of the mouse. I noticed how sliding pads have completely worn out. That was it. The sensor in the mouse eventually got out of focus and could not register movements because what ever it saw was blurred. I tried to hold it slightly higher or slide it with folded paper under one edge and it worked.

Step 2: Solution

Getting solution was very simple. I taped some folder paper to bottom side of the mouse but although it worked I didn't like the noise made by edge of the tape ripping against mouse pad. Then I tried band aid (ok, I know how it sounds but it's true) which was softer. Actually I placed two (not shown in picture, back side left bare to show wear). This introduced lift to both front and back side of the mouse and reduce friction (height change about 0.5 - 1mm). This was quick and dirty fix but it allowed me to work comfortably and submit the work on time.

    Thank you!  I was about to dispose of this wretched mouse (by tossing it out a window at great speed), but your solution has made it work!  If anyone asks, I'm just going to say that my mouse had a boo-boo.  Thanks again for a simple and ingenious solution.

    Wow thanks for figuring out my mouse problem,   I just confirmed mine is exactly the same,   I am going to heat the plastic and push them down a bit.  Cheers.

    Great instructable. I don't know whether I would have thought of that if my mouse did the same thing. Didn't realize that it had a focus point, until now.

    don't beat your self, this was not so obvious problem and  i nearly missed that little detail as well...
