Drilling the Hole
To achieve a more diffused glow that really illuminates your puck mouse, you need to drill a hole into
the ball chamber and point the LED into it.
1. Remove the circuit board from the mouse and place it as far away as the cable will allow
(see Figure 5.59).
2. Using the 7/32-inch drill bit, drill a hole into the backside of the mouse housing (the side
opposite the button), as indicated by the arrow in Figure 5.59.The hole should be just low
enough so that the rim around the top of the chamber will not be broken.The proper posi-
tioning of the drill is shown in Figure 5.60.
