Week 9 - Exciting Findings

While deciding ways to transfer the power generated from the DC motor to the actual Iphone, we were continually bouncing back and forth between using a battery or a set of capacitors. We ended up finding that we could actually use two super capacitors instead of two heavy batteries, to collect and dissipate charge between the DC-motor and the Iphone. We also found that this saved space and weight, which was extremely important as continue to determine the best way to manufacture a housing that will also serve as a case for the Iphone. We also found that due to the size of the one direction ball bearing we will be using with our DC motor, on its  shaft, we may not need to have a gear train to increase the gear ratio. This again, saves space, weight, and more importantly, reduces chances for losses in efficiency!
