ccrrrcrcrc crcrrcccrccc ... SILENCIUM!

My workstation employs a mouse which performance-wise, I really like. It is a super cheap Logitech M100. The only thing that is really annoying is the sound and cheap feel of the scroll wheel.
I know, this is a matter of taste. However, here's one to try for yourself (and this may apply, mutatis mutandis, to other computer mice too!).

The feel and sound is created by a spring mounted against the inner corrugated surface of the wheel (of course, first you need to remove the single screw on the bottom of the device... you know all about this....

Key point of this very simple mod, compared to other attempts available in the mists of the internet, is to remove the bloody click thing all together.

In order to achieve the goal, the only thing to do is gently slide out the scroll wheel assembly. There is nothing holding down said assembly, just grab it and off it goes. The photograph below shows the assembly, the clicky spring device still in place, whilst the load spring held on the axle just fell off (this spring we actually want to place into its original place when assembling the mouse again!).

Now, gently pull the actual wheel from the assembly. The clicky-clacky (ccrrrcrcrc crcrrcccrccc) spring will most likely fall off in the process. Do to the severe complexity of this stage, I forgot to take a picture... sorry for that ;-)

The following step will be to put the wheel back in its original position in the assembly, w/o the crcrcr-spring of course.

As a last step, we slide the wheel assembly back by using its guard rails. Mind the "scroll wheel click load spring"!
now w/o the noise device
Again, I leave it all to you to put the lid on it all and screw it all down by the single mounting means we had to dismantle in the first place.
As a result, I feel personally very positive about the modification. Not only is the bloody noise gone, the now freely spinning scroll wheel provides a real smooth experience.
