- With a mini hacksaw, cut openings in the back of the plastic kart top.
One opening will allow the IR detector to peek out and detect a signal;
the other opening is for the power switch in the side.
Make sure you’re using a top made of flexible plastic so it cuts easily.
Wear safety glasses in case a piece flies off while you’re cutting.- Rest the bubble on the kart, as shown in Figure 11-42.
