did all the tpu staff need new mousepads, so you guys got a bunch of review samples? lol
seriously though, nice review. maybe in the future you could find out exactly how the lube works quantitatively
it's easy to test static friction with the mouse and the mouse cord and some weights, but to test it's kinetic friction easily one would need a little spring force meter.
put the mouse on the surface before applying the lube, and see how much force needs to be applied to get the mouse moving (this can be tested using weights tied to a string hung over the edge of the table (so F=ma where m = mass of weights and a = accel of gravity) and attached at the other end to the mouse). maybe see how the performance degrades over days of use and days of non-use
the spring force meter would be easiest to test both static and kinetic friction. attach the hook to the mouse cable and see how much force is required to get it to start moving and secondly to get it to continue moving at constant speed. if you just use a weak spring, this can be accomplished by measuring the equilibrium point of a spring (like from a ballpoint pen) and measuring it's distance at the same points in the trial as above.
springs react linearly to a force being applied, so take the difference between spring length at equilibrium minus spring length at both static and kinetic friction tests before application of lube, and divide these differences by the original equilibrium spring length (will give a ration >1). these will be your two reference values (refs = reference static, refk = reference kinetic)
do the same thing with the lubed version (take equilibrium length minus (static or kinetic) length and divide that difference by the eq length). the difference between the refs and the static one here multiplied by 100 would be the percent the amount of friction was eliminated (i think. it might be one calculation away, anyways. also my negative/positive value might be opposite correct. )
Any chance we could see that?
My uncle had some generic mousepads in his van that say support dell on them, I asked if
I could have one and he said sure so I took one home. It is way better than my pokegay (pokemon) mousepad (had it since I was 6) Its colors are better for laser optics, and the material is better to move around on (mouse slides esier on it)
I got the F10.5 Func pad at PDXLAN 8
i have a beautiful radio shack thing
To #1 I was going to borrow a force meter but the only ones we have at my school are only precise to 1 N, but if I ever come across one that is more sensitive than that I will make that sort of tests. Thanks for the input guys
