In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject ...

This allows the AAduino to slot into the battery slot like a regular battery. Granted the AAduino isn't going to match an Arduino or Raspberry Pi in terms of what it can do.

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 ...

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 ...

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.

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.

This Arduino-compatible board fits neatly into a AA battery slot. Kanflo opted for this form factor to create a self-contained radio node that supplies its own power.

Fortunately, though, a decent spot welder isn’t that tough to build, as [KaeptnBalu] shows us with his Arduino-controlled battery spot welder.

Measuring Battery Capacity With an Arduino 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 ...
