Mintyboost Holder for Flashlight by brucem #3dthursday

MintyMegaBoost

Bruce Mueller needed to be off the grid for a couple of weeks this summer at the Boy Scout National Jamboree, so he converted his D-battery MagLight into a super long charging Minty Boost monster!

He shared this story about creating this project:

While cellular coverage will be good (thanks AT&T!), charging a phone will be a challenge. I was looking for a way to provide a sturdy recharging solution. After studying your battery cell information page, it became clear that a solution with 3 D cells and Mintyboost would fit the bill..

But, alas, this won’t fit in altoids tin! — Then I saw my lonely 3D Maglite flashlight. With the advent of LED torches, I don’t think I’ll ever use it as a lightsaber again, but it would make an excellent home for a mintyboost.

After taking the bulb out, breaking it and soldering in wires to power the mintyboost, all that remained was coming up with a way to hold it in the flashlight…

Fortunately, I’m the new proud owner of a Makerbot Rep2… In the attached link is my thingiverse design of a holder for the Mintyboost to put it into the head of the Maglite flashlight. It is a beautiful thing, and will keep me connected for at least a week!

And here is an excerpt of his Thingiverse from Thing 52218 description:

This bracket holds a Mintyboost from Adafruit in place of the bulb assembly in a 3-D cell Maglite Flashlight.

This thing was made with Tinkercad. Edit it online!

The Mintyboost from Adafruit is an excellent battery powered USB charger circuit. It was designed to use 2 AA cells and be housed in a mini altoid tin container. I was looking for significantly higher capacity and a rugged housing, and stumbled over my 3D cell aluminum Maglite. 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.

MintyBoost Kit – v3.0: Make your own iPod/iPhone/GPS/etc… battery-pack and recharger! This project includes all the electronic parts necessary to build your own MintyBoost: a small & simple (but very powerful) USB charger for your iPod (or other mp3 player), camera, cell phone, and any other gadget you can plug into a USB port to charge. If you have a Nintendo DS/GBA or a PSP you can buy charger cables from us, too. The charger circuitry and 2 AA batteries fit into an small space such as an Altoids gum or mint tin, and will run your iPod for hours, 2.5x more than you’d get from a 9V USB charger! You can use rechargeable batteries too. (read more)


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
