This week, the final ordered parts arrived. We took the voltage booster and connected it to the generator, which was connected to the gear train in the crank flashlight. We connected a USB phone charging cable to the voltage booster and cranked the gears; to our amazement the phone charging sign came on. This was a sign that our product has the potential to work.
The next step is to finish making the mechanical wedge that will be used in the shoe to harness the energy when the user takes a step and to place all the components in an enclosure in the shoe sole.
