Do those battery hungry toys drive you crazy? Are you worried about keeping 3 small children happy during the next family campout without running to Radio Shack every day for batteries? If so prepare to be amazed on how you can greatly extend the life of a simple battery operated lantern with this simple mod.
Step 1: Gather the Materials
For this project, we will need a small battery operated lantern. This one is a pretty nice design as it is small, lightweight and has a really nice on-off pushbutton. It also has lots of room to add additional circuits. Heck- you can probably fit an Arduino in this thing!
Materials required are: lantern, soldering iron, 1K ohm resistor, super bright LED, and a small piece of stranded wire.
