Hi All. I made a tiny board that allows you to bring the power to your project, and not the other way around. A single AA battery is used to provide breadboard power of 5V or 3.3V (or other voltages by tuning the feedback resistors). A boost regulator provides the voltage.

BooSTick provides extremely small and convenient portable regulated power to Arduino, wearables, DIY, and other projects. The entire package is about the size of a single AA and can drive Arduino projects for many hours at a time. When the battery is used up, pop another in for continued use. Or use NiMH rechargeable batteries to reduce your footprint. I use my prototypes all the time. It's great to not need a power supply for every little project. Everything's untethered and my project bench is clear of wires.
