Motion Detector Fix
After a ten minute brainstorm session, we found ourselves with a spread of thirteen ideas, some more practical than others. We narrowed our possible fixes down to two, a pulley and just using a long pole to wave across the room, having received new knowledge that we were to construct a prototype using only our imaginations and the materials placed in the back of the room, such as pipe cleaners, twine, and a few long poles. We decided that the most reasonable option was to construct a pulley, seeing as Mr. Lieb is not training for a strong man competition any time soon, and a pole that would not go limp while reaching that far would be quite heavy. We used one of the long poles, some twine, and a circular plastic piece with a few punctures. We tied the twine around the pole and wrapped it around the plastic plate, leaving the majority of the twine as slack. The idea here is that the slack would travel all the way to Mr. Lieb's desk from the plate, mounted on the ceiling in the vicinity of the motion detector with the pole is suspended in the air. When the twine on the desk in tugged, the pole moves and the motion detector senses this happen, turning back on the lights.
