The Raspberry Pi Foundation launches an official case for the popular Raspberry Pi micro-computer, one the foundation says has "the kind of real beauty and design that our products try to encompass."

Designed by Kinneir Dufort, the Rapberry Pi case has a removable top and sides to accommodate particular deployments or environment. It also hackable, with features specific areas of weakness allowing for drilling or mounting.

Microsoft shows off what it describes as a "an elite controller for the elite gamer" at E3 2015-- the Elite, a redesigned Xbox One wireless controller with hot-swappable components and customisable builds.

Users can replace thumbsticks, paddles and D-pads with multiple options included in the package. The controller also features 4 interchangeable paddles on the back to add even more game controls, while the triggers can be set to hair triggers via lock switches.

Further fine-tuning comes through a companion app (Xbox One and Windows 10) allowing users to adjust thumbstick sensitivities, button assignments and the like before saving as multiple user profiles on the cloud. Users can even load up to 2 profiles on the controller itself, and switch between one or the other via built-in profile switch.

The humble keyboard might get a touch-sensitive upgrade in the near future through the SpaceBar, a piece of Synaptics technology allowing OEMs to add "unique gesture features" to keyboard space bars.

The SpaceBar essentially turns the space bar into a touch-sensitive surface complete with customisable gesture controls, such as thumb swipes (for word selection) and touchscreen-style double-thumb pinch zooming. Also included are 5 "logical buttons" users can program via macro editor to provide further shortcuts for desktop functions or game controls.

Ricoh reveals what it calls "Energy-Generating Rubber"-- a flexible material able to convert pressure and vibration into electric energy with "high efficiency."

The company says the material combines the best properties of two current piezoelectric (as in able to convert mechanical strain into electrical charge), ceramics and polymers. Ceramics generate "relatively high" electricity but are fragile and heavy, while polymers are flexible but only produce "very slight" power.

On the other hand the Energy-Generating Rubber promises to be a better solution, being a soft and flexible sheet with the electrical output of piezoelectric ceramics. The flexibility also allows for easy processing, the company adds.
