Turn a Flashlight into a Long-Lasting Mobile Device Charger

Bruce Mueller was looking for a way to charge his phone for a couple of weeks while off the grid. So he combined the Mintyboost from Adafruit (designed for two AA batteries and usually tucked into an Altoid tin ) and combined it with his D-battery Maglite, for higher capacity charging.

With a little tinkering of your own, you could create your own flashlight-Mintyboost. Bruce writes:

Removing the bulb and reflector, I created a space to hold the mintyboost board. By disassembling (breaking) a bulb, power can be drawn from the bulb socket.

I sliced it in Makerware, medium quality (.27 layers, 2 shells, 0% infill). It sticks to the plate like glue ? take your time and a nice spudger to get it off...

He also offers the 3D plans for the Mintyboost-holding bracket.
