Hackaday Prize Entry: Pi-Driven Google Glass

[Ricardo Ferro] didn’t want to buy a Google Glass, so he made his own.

The Raspberry Pi Zero Prism consists of a 3D-printed headset the side-pieces of which hold a variety of electronic components, including a Pi Zero running Raspbian Jessie, a Pi Noir IR camera, a WiFi/Bluetooth module and a whole mess of SMD tactile push buttons. Video output is provided by a Kopin 922K display module. This module is usually used in smart goggles and uses a prism to reflect information into the wearer’s field of view.

One application [Ricardo] envisions for this Open Source Google Glass is …read more

Homemade Smart Glasses shows why Smart Glasses are Hard

[Harris Shallcross] decided to build a pair of smart glasses and recently completed a first prototype of his project ‘Ochi’ – an STM32 based, BLE-connected, OLED eyeglass display. There are of course several homebrew smart glasses projects out there; many are more polished-looking and nearly all of them also display information from a smartphone over Bluetooth. This one is interesting partly because it highlights many of the design challenges that smart glasses and other near-eye displays face. It also demonstrates the iterative development process: begin by getting something working to learn what does and doesn’t cut it at a basic …read more
