We’ve seen Arduino-powered Twitter machines, and even some that can send text messages, but how about one that’s a video phone? That’s what the guys over at Cooking Hacks put together with ...

These include a rechargeable battery, a temperature sensor and a built-in radio that allows one Pinoccio with a WiFi shield to communicate wirelessly with other Pinoccios.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

A Swedish software engineer makes a wireless Arduino clone called AADuino. The system fits neatly within the form factor of an AA battery.

An amusing aspect of the board is how Kanflo attached battery terminals, including a spring, on the board itself. This allows the AAduino to slot into the battery slot like a regular battery.

Behind the delightfully punny name, you'll find an Arduino-compatible board the size of an AA battery.
