Hello world!


I used:


DC gearmotor


9V battery


TIP120 transistor 

I'm interested in kinencted sculptures, so I tried to build a quite simple one. The weight of the objects limits the slowest speed it could be, so seemed too violent the magnifier's motion was! Have to figure out a more elegant way for the magnifier to rotate.


Last weekend, I went to pace gallery to see an exhibition of Alexander Calder. I noticed that the new building's elevator had a very special interactive interface.

How it's used: 

Click on the cellphont-keyboard-like-button, the floor number on the screen will be highlighted.


Unlike normal elevators, the button and where it lights up is separated, so it took me at least 30 seconds to realize I should refer to the screen to check if I entered the right floor number.


At first, I thought it was useless and wasteful to put so big a LCD screen here. Only after thinking for a little while, it's understandable for me. 

Firstly, gallery is a special location, in which the works shown in each floor is constantly changing. It is the main difference from other buildings. The LCD screen helps people to figure out in which floor there is whose works, or which floor they can't enter, through the most evident way, without seeing a map. 

Secondly, this pace gallery is much bigger than a normal one that usually has only one floor, as well as smaller than a museum which usually offers a map. I think it's a clever and tricky way to solve this problem through elevators - people even won't notice the convenience it brings.

However, I still think it's a waste of electricity. As a designer, I always wonder whether we really need such convenient technology, taking up energy, just to solve a quite small problem?
