Got the new iPhone? Need to charge it on the go? Well, it’s not a problem with the new MintyBoost 3.0 from the Maker Shed. Build your own MintyBoost: a small and simple (but very powerful and very MAKE-like) USB charger for your iPhone, iPod, or other MP3 player, camera, cell phone, and any other gadget you can plug into a USB port to charge. Mint tin not included.
