IoT and wearable devices have become essential tools in our everyday lives. From health monitoring wearables to smart home sensors, they rely heavily on battery power to function. However, optimizing ...

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 adhered to ...

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. The ...

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 a AA ...

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 ...

You might think that there could be no form factor that has not as yet had an Arduino fitted in to it. This morning a new one came our way. [Johan Kanflo]’s AAduino is an Arduino clone with an onboard ...

The Arduino based capacity tester of true battery power is capable of measuring almost any type of rechargeable or non-rechargeable batteries by fully discharging the battery with known current and ...
