[해외] Raspberry Eye

안녕하세요 버섯돌이 유재성입니다.

라즈베리 파이 사이트를 방문하니 구글 글라스 프로젝트인 라즈베리 Eye가 있네요.

안경이 후덜덜하지만~ 나름 도움이 될만한 자료들은 있을듯 싶으니 관심있는 분들은 살펴보세요~

DESCRIPTION

I wanted to do something interesting with my RPi and a 2.4" TFT 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 320x240 resolution using X is not too exciting. Display brightness is sufficient if ambient light is not too bright. 

Here is a demo video: https://www.youtube.com/watch?v=lCYnIHqwIJU

DETAILS

 

A drawing of the mounting assembly: https://www.dropbox.com/s/rkcvja6qljtskzb/rpi_eye.pdf

I've bought the beamsplitter here: http://amzn.com/B000NSMODK

The screen is ITDB02-2.4E from ITead Studio

The framebuffer driver for Raspbian is here: https://github.com/notro/fbtft (my version is slightly modified to produce a mirror image)

For the lens look for a "credit card size 3x fresnel magnifying glass"

  Added links to components and mounting assembly drawing to the "details" section. Then tried to make a short video using GoPro, first couple of takes were not good. Will get some sleep, try again in the morning.
