The input power is coming from a small wind turbine that produces 10A and 3V at the rated power. I was hoping to design the system to produce a constant 5V output as soon as possible. I bought a small boost converter to power the Arduino that turns on at .5V. So I was hoping to start outputting 5V from the boost converter I'm designing at around the same .5 Volts. But that is starting to seem unlikely.
