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 ...

So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging requires ...

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 ...

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 ...

This Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...

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 ...

The hardware tinkerers and prototype mavens out there will invariably have stumbled across the Arduino platform. Completely open source and always pushing the limits for collaboration, there are a ton ...

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 ...

What do you do if even the smallest Arduino boards (or their clones) are too big for your homebrew project? If you're Johan Kanflo, you find a way to make them even smaller. His AAduino project turns ...

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 ...
