Switches were installed by holding the polycarbonate sheet in place then moving the switches into place until they closed. To increase the push from the switch the lever arms were bent. This reduced the leverage on the switch plunger. The switches were installed away from the corners since it was easier to position them for installation and should reduce the pressure on the switch so they can rebound after a press more easily.

The protoboard which holds the Arduino and connects to the components was given a hole large enough for a #4 screw (3mm) and attached to a white laminated board between the quadrants. The 9V battery was installed directly above the Arduino but removed since it would be difficult to replace and disconnecting the battery is how the prototype will be turned off an on.

The light hoods were installed in the corners by applying glue to the wood and pushing down on the light hoods over the glued area. A strong general purpose adhesive was used and a popsicle stick was used to spread the glue and keep it away from skin contact. The glue was also used to mount the reed switch above the Arduino so it can be activated once the clear sheets are installed. The rest of the light locations were marked with pencil so the lights are spaced uniformly.
