Make your own iPod battery-pack and recharger is easy.Make your own iPod battery-pack and recharger! Build your own MintyBoost: a small and simple (but very powerful and very MAKE-like) 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.
The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours, 2.5x more than you'd get from a 9V USB charger! You can use rechargable batteries too.Is good for outdoor activity while you travel.
