What do you do if even the smallest Arduino boards (or their clones) are too big for your homebrew project? If you're Johan Kanflo, you find a way to make them even smaller. His AAduino project ...

Born from Johan Kanflo's mind, the AAduino, so named because of its size, can, almost, conveniently fit inside a 3x AA battery holder for maximum space footprint efficiency.

Based on the Tiny328, AAduino takes the platform to its sexiest form factor yet: Turning a three-AA battery holder with two batteries in it — the third battery compartment holds the AAduino ...

One of the great things about the Arduino is that it’s totally open source so you can make your own variations on it. Case in point, DIYer Johan Kanflo’s AAduino, which comes in at the size of ...

You can also go the 9v battery route plugged into the on-board regulator of the Arduino but the low mAh rating of a 9v won’t allow your project to stay running for very long.

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.

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 available. Ignoring the shiny packaging and its ...

A Swedish software engineer — Johan Kanflo — has made a wireless Arduino clone called AADuino, which is the size of an AA battery. Kanflo explains that the AADuino has an onboard RF module ...
