Basically any "Arduino compatible" that runs an 8-bit AVR with an 8-16MHz clock will work. Additionally, the Arduino Due and Teensy boards are compatible with the Neopixel lin.

The rest of the build is pretty plain vanilla — an Arduino Nano clone, a DS3231 RTC, a Lithium battery, and some buttons, all housed together in a laser cut enclosure which follows the figure of ...

Mad scientist shrinks Arduino to size of an AA battery Haje Jan Kamps 2:30 PM PDT · April 19, 2016 ...

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.

[JonBush] recently did a beautiful build of an Arduino-based fireworks controller. Seriously, it looks like a movie prop from a summer blockbuster where [Bruce Willis] is trying to decide what ...

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 ...

The EnergyShield Arduino rechargeable battery has been created by Nightshade Electronics and has three main internal functions including a circuit to boost the battery’s nominal voltage of 3.7V ...

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.

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 ...
