I need someone to explain this to me.

Seeed Studio shows off their wares

Everyone’s favorite Open Hardware store – Seeed Studio - was at Maker Faire this last weekend. They showed off a bunch of cool toys, oscilloscopes, Arduino shields and other hardware goodness, but one of the more interesting products was from their B Squares line.

As [Colin] from Seeed showed us, each B Square is a small plastic enclosure about the size of a drink coaster. The corners of these squares are clad in metal, and each one has magnets inside. The idea behind the B Squares system is to provide power to other B Square boards via magnetic connections.

So far, Seeed has released an Arduino square, battery, solar, and LED squares, as well as iPod docks and prototyping boards. These boards can also be orthogonally, meaning it’s entirely possible to turn six B Squares into a B Cube.

These magnetic connections only provide power connections; there is currently no way to transfer data between different B Squares. We suspect, though, that anyone wanting to replicate the Apple MagSafe power adapter and invent a magnetic I2C bus would find these boards perfectly suited to the task.

Solar-powered bird house Tweets using B-Squares

This bird house will tweet to let you know when the occupants pass through the door… err… hole. It uses solar panels to keep a battery topped off, and an Arduino along with an optical sensor which monitors the doorway to pass along an alert via an XBee module.

Admittedly, the video after the break is a bit tongue-in-cheek and doesn’t safeguard against the elements, or even against bird poop. AND it’s basically an advertisement for B-Squares. But we still like it.

These squares use magnetic corners to connect the solar squares together, as well as the squares that house the Arduino and the battery. These magnetic corners also act as the power and ground rails. Two nails have been pounded through the roof of the bird house, acting as a surface to magnetically attach the solar panels to, as well as a conductor to pass the power rails through the wood. It’s no wonder that B-Squares are closing in on  raising five-times their Kickstarter goal.
