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 Aardu… ...

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.

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.

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 ...

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.
