Once turbines are spinning and generating electricity, attention can be turned to what to do with this power. Designs are shown here for powering circuits or LEGO motors from wind energy. The power from a turbine generator can be of varying voltage, so solutions are presented in this chapter to regulate voltage or store charge in a battery.
LEDs Powered by Wind
We’ve always been amused by making things light up, with light emitting diodes (LEDs) a favorite subject. So, we built a circuit to power LEDs from the turbine output. This ...
