Thanks to Alastair Bland for the idea.
Here's how it works:
The cable from the generator leads first to the circuit board's bridge rectifier, which converts the AC to DC. The up-and-down, positive-to-negative current becomes a steady positive current. Then, the cap levels out the DC voltage, producing a steady voltage inflow to the voltage regulator, as the phone only needs 5 volts to charge. Fast pedaling can produce 30V or more, which is enough to fry a cell phone. The regulator puts a five-volt ceiling on the power entering the phone.
