Pole Ergo (I think his name is Guy, but I’m happy to be corrected) from Lyon in France has taken a Raspberry Pi and made it ultra-mobile using a hinged 3D-printed case. He’s removed several components of the Pi itself, shortened the GPIO pins and then added a small Bluetooth keyboard for input. A 5″ screen and a LiOn battery completes the picture. He’s written the project up on Thingiverse, where you can also download the case printing files and see a lit of photos of the build. Unsurprisingly, the write-up is in English and French.
