Ochi, A DIY Wearable Computer Display

Harris Shallcross, apparently not content with wearable computing devices now for sale, decided to build his own using a tiny display and a lens snagged from a Google Cardboard setup.

His display system, named “Ochi” after the Romanian word for “eye,” uses an Android app to pull data from the BBC News RSS feed, as well as weather information. This data is then sent to the glasses over Bluetooth, where a STM32F051K8 microcontroller does drives the display.

Physically, the display is mounted to the glasses frame on thick copper wire for adjustment, and magnified using the Cardboard lens in a custom 3D-printed holder. In order to ensure he could fit enough data onto the screen, Shallcross even wrote his own small font to squeeze everything into the available display real estate.
