prototype

Today i finished my prototype for time telling device for the blind, it was going pretty well.



I chosed paper to do this prototype rather than card board is that I found card board is too thick for this small device that will fit in people's palm, but paper also have problem, it's a little soft and unstable, so I tried to use some hard paper.

Another a little problem is the distance between hour panel and minute panel is too close, this causes not easy to touch the sectors so as to tell the time. So at last I add a little piece of foam between two panels, this keeps apart two panels from a small distance. I think in the real project model, its material will be plastic, and this problem will be solved.
