Can’t afford to buy a Google Glass? You could always try to make yours. Noe Ruiz at Adafruit has designed a GLASS like device powered with a Raspberry Pi. It can be attached to your prescription glasses. If you have a 3D printer, you can download all the parts, take part a pair of video glasses, and connect a Raspberry Pi. All the steps are included on Adafruit.com. Pretty special if you ask me.
