Optical mouse trackball

[hector213]

hello guys i thought i would share my small build of a mouse i turned into a trackball..

since i didn't want to spend a lot of money for a real trackball that i would only use on

occasion.. so i set out to build one i found on Google using a roll-on deodorant ball and an optical

mouse i bought at a local goodwill, some scrap wood and glue..

everything i used was stuff i had laying around or i bought but i spent less than $5 for the

build..

i was surprised how well it worked, it actually works better than i thought.. all i did was invert a few things

in mame and it works perfect.. on mine i also desolderd the tiny micro switches and hot glued them to a button on

top for whatever i needed it for..

the ball does light up red but you cant really see it cause of the flash but i think it looks pretty good.. what are your guys thoughts?

i didn't really take pics while building it since i didn't think it would actually work well, but it did..

but maybe ill make a revised one and take pics along the way..

as for the link for where i got the idea just Google "optical mouse into trackball" and its an inscrutable..
