This is the beginning about a project to convert a optical mouse into a Trackball for a cheap multimedia kiosk peripheral. We can´t use the mouse as the original way, because it can be damaged or stolen. So we propose this PROTOTYPE to make some experiments and see if it works. Ok so what we need is:

1 Empty Roll-on deodorant
1 Cutter
1 Cutting pliers
1 Glue or sillicon pistol
1 Optical Mouse

Step 1: Getting the ball

Ok so we need the ball of the roll-on deodorant so we take our cutter and simple cut the upper part of the dedorant case where ball is. Not to be necessary perfect in the cut

 Important: you need to leave some material where the ball can support itself without touching the superfice where it will be rested.
