Turn the handcrank for a little while and then push the button on the switch and watch as the visual multimeter displays the amount of power the battery has. Set your powerPlant out in the sun and monitor how much energy it collects. Then use your powerPlant to power devices. We powered our mini arduino with the powerPlant, see what you can power!
Modify your powerPlant to suit your needs. John O'Malley changed out the gears for a rig on his bicycle (see images below).
Have Fun!
