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 Aarduino ...

Last year, the Raspberry Pi Foundation surprised the hobbyist world with its RPi Zero, the smallest incarnation of its popular single-board computer. However, that has nothing on this even smaller ...

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. Through creative wiring, it even fits inside a ...

Arduino developers and hobbyists looking for a portable battery shield to powered their projects might be interested in a new shield called the EnergyShield Arduino rechargeable battery.

Behind the delightfully punny name, you’ll find an Arduino-compatible board the size of an AA battery. Growing up in the bad old days, you’ll remember what an epic pain in the rear-end it ...

It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects. The usual way to measure VCC is simple, but has ...

The other application I found was as a power source for an Arduino project. This one required the purchase of an appropriate battery holder from Digikey: The 18650s pack a punch, and make a nice ...

The latest addition to my collection is a cheap portable power supply module labeled by its seller as “18650 Battery Shield (V3) for Raspberry Pi & Arduino”. The pictured shield holds a 18650 Li-Ion ...

Well, get a load of this, makers: An Arduino clone that’s literally the size of a AA battery. Sweden-based coder Johan Kanflo was looking for a way to make the Tiny328, which he was using in his ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...
