Today, I have mostly been fettling...
... my old PC mouse!
I prefer using a mouse with my laptop. The track pad is ok for occasional use but a mouse is much better for intensive graphical work and I have been playing about with Xara Photo & Graphic Designer recently.
I really liked my old Microsoft mouse but it has died the death. (It looks like somebody immersed it in a vat of strong coffee, though I don't remember any coffee break accidents. Anyway - it is no more; it is an EX-mouse.)
I have a couple of cordless mice but they play up after a while; it is probably a driver issue. I haven't been able to get them to behave themselves so I have put them to one side for now.
I found a cheapo Labtec corded mouse in the drawer of my desk and I have been using that. It isn't as good as the MS mouse was but I can live with it. Well, I
could until the point where the scroller wheel started playing up. It felt like my finger was slipping on the rubber wheel. About 3 times out of 4 there would be slippage rather than, er, scrollage. It was starting to do my head in!
Ideally I would have bought a new MS mouse but funds are tight, and I don't like binning things that I can repair so I decided to sort the mouse out.
Close inspection revealed that my finger was
NOT slipping on the rubber wheel - it appeared that the rubber wheel itself was slipping inside the mouse. I disassembled it and discovered that the rubber wheel is in fact a doughnut-like ring fitted round an inner plastic wheel on a little shaft. I could feel that the rubber was not gripping the wheel properly. When I removed the ring I could see that it was relying on friction between it and the wheel, but the wheel's outer edge was perfectly smooth so there was little friction between the two. I thought about trying to superglue the two items together but they looked like they might be a bad combination for superglue - I haven't had much success with materials like that. Then it dawned on me that I could create the friction needed by roughing up the edge of the wheel. I took a sharp knife to it and scored a deep crosshatch pattern onto it. I refitted the ring and hey presto - the two stick together nicely.
I just put the mouse back together and it works perfectly. Yay -
a few crisp tenners saved*** and another chunk of plastic did not end up getting chucked away!
*** I just looked up how much corded mice cost. You can actually get them for under £10 now, so not a huge saving, but still - waste not, want not!
