If the styling of Google’s new Google Glass eyewear is not to your liking and you prefer something a little more hardware inspired that you can build yourself.
You might be interested in the Raspberry Eye which is being built using a see-through display using printed components and cheap off-the-shelf parts and is the brain child of Roman Rolinsky.
The Raspberry Eye includes a $35 Raspberry Pi mini PC and a 2.8″ LCD display which is enclosed in a 3D printed chassis. A 3x Fresnel magnification lens has been placed over top of the LCD screen to create a larger view and reflects the image onto the mirror which is placed directly over the eye creating a see-through display.
“I wanted to do something interesting with my RPi and a 2.8” LCD. Google Glass was hot in the news, so I’ve decided to hack something similar. The semi-transparent mirror was extracted from Eye of Horus Beamsplitter, and the projection lens is cut from a plastic 3x Fresnel magnifying lens. The box and mounting parts are 3D-printed from ABS. Head strap is for GoPro. One RPi USB port is used for WiFi, and second for 2.4Ghz small wireless keyboard/mouse combo. All together cost around 100$.
I haven’t figured out a good option for the power supply yet, and don’t know if this thing can have a practical application. The display driver is fbtft framebuffer, so both text and (non-accelerated) graphical modes are possible, but with 320×200 resolution using X is not too exciting. Display brightness is sufficient if ambient light is not too bright.”
The Raspberry Eye project is still currently under development but can be followed from the official website created by Roman Rolinsky as the project develops and new features are added over the coming months. For more details on Raspberry Pi displays and HATS jump over to our essential guide.
