We’ve seen [Johan]’s AA-battery-sized Arduino/battery crossover before, but soon (we hope!) there will be a new version with more MIPS in the same unique form factor! The original Aarduino ...

Arduino developers and hobbyists looking for a portable battery shield to powered their projects might be interested in a new shield called the EnergyShield Arduino rechargeable battery.

This allows the AAduino to slot into the battery slot like a regular battery. Granted the AAduino isn't going to match an Arduino or Raspberry Pi in terms of what it can do.

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.

The hardware tinkerers and prototype mavens out there will invariably have stumbled across the Arduino platform. Completely open source and always pushing the limits for collaboration, there are a ...

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

The Qduino Mini is the first tiny Arduino compatible board that has a built-in battery charger and fuel gauge, watch the video below to learn more from its ...

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 ...

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.

Fortunately, though, a decent spot welder isn’t that tough to build, as [KaeptnBalu] shows us with his Arduino-controlled battery spot welder.
