An anonymous reader writes: Johan Kanflo has managed to make the already small Tiny328 Arduino clone into an even smaller computing platform about the size of a single AA battery. Not only will it fit in a typical AA battery holder, but it will actually draw power from the batteries beside it as it’s wired in “backwards” (with the + and – poles reversed). The Arduino platform consists of open-source hardware, open-source software, and microcontroller-based kits, making it easy to (re)program the processors, and develop software for hardware applications using a java-clone and an easy-to-learn IDE. For those interested in the AAduino, Johan has made his creation available online on Github with instructions and schematics to build your own.
