group 9 / Richard, Yen

+ Input component
motion sensor.

+ Processing component

basic stamp.

+ Output component
flexinaol wire.

+ Scale of a single "module" if you have one
pendant light fixture.

+ Number of modules you will create
1 prototype.

+ Siting (vertical, horizontal, indoor, outdoor, in a quiet environment, etc.)
indoor hanging from ceiling.

+ The "twist" of the project

using minimum movement create maximum enviornmental change throught light/shadow.

+ Vendors of all materials you will have to buy

parallax / motion Sensor.
dynalloy / flexinol.

+ List of technical issues and tests you will have to conduct in the
next five weeks

the tension of the flexinal wire.
how to control the open and close of the tube.

We reconsider the problems that came to us during the process. One of the biggest one is the friction of material. We choose plastic tubes to be our cells but they do not perform as we thought. They couldn't form a effective back and force movement. The original idea is to use the minimum input to achieve maximum output. We disign some movement which motivated by just a few cells.

Another big issue is the tension oh the flexinol wire. We couldn't come out a way to maintain the tension. Once it lose the tension, it will become less effective, even zero offset.

Now we adjust a little since one of us drop this class. We keep the basic idea of using little movement to achieve maximum performance. We change the material from plastic tubes to paper and the destination is to build a light fixture which can adjust by the sensors to create some relative effect from human movement.
