I missed class on Friday because I was off campus because of a religious holiday. On Tuesday, I got straight to work on the mechanics of the Great Hall room. This room had begun to be built on top of the Chamber of Secrets, and in this room, Kaity and I want to stage the final battle between Harry and Lord Voldemort from the final Harry Potter book. Today, I worked on building the mechanics of it. I began by thinking of making another motion module, the one that goes back and forth. However, this seemed very impractical because I wanted to the structure to go farther than the 40 tooth gear allowed. When I consulted Professor Berg about this problem, he suggested a rack and pinion structure...(or at least that's what I believe it's called...). This was an innovative way to make the structure go farther forward. The problem here is that, the farther forward the structure goes, the farther longer it is, and the farther back it goes as well. We have limited space in the back, because if it goes too far backwards, it will run into another room in the castle.
