Makers looking for a more substantial portable battery pack that they can make themselves should check out this this DIY power bank ...

Arduino’s new power management library provides developers with the tools they need to reduce power consumption, extend battery life, and enhance performance across various devices.

Putting the Arduino inside its own battery pack makes a very neat and compact self-contained unit. At the heart of the board is an ATmega328 clocked at 8MHz to reduce power consumption and fused ...

Kanflo’s project is a wireless Arduino clone that’s meant to operate in a way that doesn’t take up a lot of battery juice, so it’s pretty low power.

Measuring Battery Capacity With an Arduino Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices ...

A Swedish software engineer makes a wireless Arduino clone called AADuino. The system fits neatly within the form factor of an AA battery.

This Arduino-compatible board fits neatly into a AA battery slot. Kanflo opted for this form factor to create a self-contained radio node that supplies its own power.

His AAduino project turns the already miniscule Tiny328 Arduino clone into an even smaller computing device that's about as big as an AA battery.
