I worked very hard on the final – I think for me this was the most trying work that I have ever done. The technology aspect of it was daunting, but so was the actual construction. On one of the first days that I met with the group I was given the task of unscrewing all the spokes on one bicycle wheel – the wheel was old and rusted together and it took me a tremendous amount of time to do this physical labor. I have never constructed anything before or worked in a woodshop so this was a particular challenge for me.
As the days went on our group met more and more often. We ordered a series of parts online – including some super bright, 3 watt LEDS and a Hall Effects sensor. Essentially, the way the wheel will be constructed is that at every point where there will be an animation, a magnet will be placed – these magnets will be read by the Hall Effect sensor in our circuit which will then tell the LEDS to flash.
