Open up a dollar store solar path light and see what useful parts are inside that we can use for other projects.

These little lights are amazing and contain lots of useful parts that can be used to make other projects such as our homemade solar battery charger.
Another nice part you can find is a dc to dc step up voltage regulator. These little devices step up the 1.2 volt battery to 3.2 volts to drive an LED.
