Mini power plant for small projects
Plug in a solar cell or use the hand crank to create your personal source of power. The latest version of the PPP charges 9V batteries.
PLEASE refer to the detailed instructions on Instructions.
This specific project was created with Jennifer Broutin and Carmen Trudell with Mike Dory.
NOTE: For the zener diodes on the circuit, place then as follow
Z3 - 4736A
Z2 - 4735A
Z1 - 5231B
