The 1Sheeld, a single shield that lets you replace all of those other shields with your smartphone. Today, that project went up on Kickstarter and almost immediately destroyed its fundraising goal.

OMC's H19 fiber-optic shield has been adapted as a stackable add-on for the Arduino Uno. It’s designed to simplify the integration of fiber-optic data links into microprocessor-based platforms.

The Shield itself is getting a quiet upgrade in the process -- the software both takes up a smaller footprint and can now talk to the world in the background while the Arduino keeps on keepin' on.
