Sim and I try to make sure all the technical issues this week, and things go well. But we make a little change to the components we will adopt. 

Firstly, great thanks for Yeseul lending the wind sensor to us, super nice to detect data. And we try to use the air pumps but it’s super noisy! We decide to replace it with the 360 servos. The reason to use a servo is that we want to make a huge kaleidoscope in the cube, when people blow on the wind sensor the base plate will rotate by the servo. So the behavior is like playing with a hand-held kaleidoscope, which changes through rotation. 

Sketch:

We have discussed the fabrication parts and tried to collect all these materials in days and start to make the cube as soon as possible.
