[Codeninja] has been sending us some great hacks over the years, and we’ve just learned that his attention has been on building wearable computers lately! He’s currently on histhird iteration of a Google Glass-like prototype, which features a motorized element which allows for the retraction of the screen.
There’s not too much info on his blog about them, but we do know he’s using a Raspberry Pi, a few small servos, and a pico LCD screen. Most of the frame is 3D printed, and it also features a hidden camera, accelerometers, and a few environmental sensors.
He’s uploaded an animated gif of the mechanism that moves the display away from his eye, and it looks straight out of some science fiction movie — check it out after break!
