Battery-topper flashlight

Battery-topper flashlight


Here’s a simple project for making a flashlight that sits on top of a 9-volt battery. Less expensive than a flashlight, and quite small and convenient! One LED is best used on top of two AA batteries, but throw a few more LEDs in series and you’re in business.

    This is nice, because for quite some time now radioshack has been selling 2 x AA holders that have a 9v clip ontop … you know because powering a 9v device with 3v is the norm… now that product has a use!
