Title: Mouse hacks and mouse speed
Post by: SirPoonga on March 16, 2002, 01:23:01 pm
I was wondering about mouse hacks.  I have the oscar spinner (and same mouse for trackball, Kelsey, going to solder it tonight, if works will have pics on my website soon....).

Now, it move the windows cursor slowly.  Is that because the optic disc only has widely spaced grooves and only 24 of them?  A real mouse has about 100 closely spaced, right?

SO if I want my trackball to act like a pc trackball I will need a disc with more grooves, right?
If so I get to use the encoder program in the utilities section here and the transparencies that came with my epson 785.  Woohoo, print an optic disc at 1400dpi....

This typically isn't necessary for trackballs.  The spinner has the encoder wheel directly connected to the same shaft as the knob, so you have a 1:1 rotation ratio with the spinner knob and encoder wheel.

A trackball has a "secondary gear" ratio, so to speak.  Not exactly the correct terminology... it escapes me right now.  Anyway, you roll a 3" trackball, which contacts say a 1/4" shaft.  Now you have a much larger rotation ratio.  A small turn on the trackball makes the encoder wheel turn many times.  Long story short, you might just want to see how it works as-is before messing around with replacing the encoder wheels, as it will probably ok with the standard wheels.
