Arduino clone is as small as an AA battery
What do you do if even the smallest Arduino boards (or their clones) are too huge on your homebrew undertaking? Should you’re Johan Kanflo, you discover a option to make them even smaller. His AAduino venture turns the already miniscule Tiny328 Arduino clone into a fair smaller computing gadget that is about as huge as an AA battery. By means of artistic wiring, it even matches inside a typical battery holder and attracts energy from the batteries within the remaining slots. He needed to underclock the processor to increase to the battery life, however it’s in any other case as succesful as its regular counterparts.
You are not about to purchase a prepared-made AAduino, however you do not have to. Kanflo has posted directions and schematics each on his personal website and on GitHub, so you’ll be able to replicate his invention your self. That is primarily helpful should you’re constructing an additional-compact gadget (Kanflo wanted this for a radio node, for example), however it exhibits that even daunting measurement necessities may be solved with a bit ingenuity.
