Step 1: Step 1
Take off the two little screws that are holding the heatsink and the fan together. Then take your pliers and cut the fan out of it's frame.
Step 2: Step 2
Step 3: Step 3
The idea is to get the air flowing against the player's palm. We need to get some air somewhere so I made a few holes to the side of the mouse to be used as an intake. You can also drill a hole for a switch if you like to add one. Could be useful if you want to turn this thing off :)
Step 4: Step 4
After a while, nice set of holes. Not quite symmetrical but should work.
Step 5: Step 5
Made a little platform with a rubber pad. You can use a nut, cork from a bottle etc. This is to ensure that the blades of the fan doesn't hit the case of the mouse.
Step 6: Step 6
Some instant glue, few solders and you are ready to test this. Just take that +5 volts anywhere you can find it. Best place to find is to take it straight from the ps2 cord. Other good place to look is the logic circuit. I took it there. The method used is described in LogoMouse article.
Step 7: Step 7
Ready to be tested... And it works. :) There is a noticable breeze coming out of the mouse. For the optimal performance you should try to make more or bigger holes than I did. There is too much material blocking the best air flow.
