foot operated computer mouse

Step 5 Mouse modifications

photo 1: Removing one screw allows that end of the cover to be lifted then snapped off the base. Note the green rectangular click switches and the switch under the scroll wheel axle. The circuit board easily lifts out, which allows the scroll wheel to be removed.
photo 2: The cord reel can be discarded if desired by removing a screw and prying it open.
photo 3: Excess plastic parts snap off of the cover.
photo 4: Two1/4-inch dia hex-head bolts, one-inch long, washers inside and outside, fit through existing openings, the square one drilled to size.
photo 5: Bottom of the circuit board shows the two outboard solder connections of each click switch. A length of stranded hookup wire is soldered to each. Switches may be left in place, but I unsoldered and removed both, plus the scroll wheel switch, for possible use in another project.
photo 6: Scraps of the foot board material aid bending two mounting brackets from sheet metal strip 1 inch wide, 0.080 inch thick. The brackets, shaped with the mouse assembled, will position the mouse's magic navel just below flush with the foot board's upper surface. Lock washers and nuts attach the brackets to the mouse's cover.
