PROJECT 3 – SELF CHARGING COOLING FAN In this project you will use your harvested and stored energy to power a bigger device: a motor that spins a fan. This device will charge up the Solar Store when the sun is out, and uses a simple home-made switch to allow you to decide when to transfer the stored energy to the motor to spin the cooling fan.
Connecting Up
By using two separate alligator clips, you can make your own simple switch. Touch together the ends of the two white alligator clips to enable the Solar Store, and if there is enough energy stored then the fan will spin. Disconnect the two white alligator clips to turn the fan off.
