3D printed smart glasses let Linux appear on your face

Posted on August 15, 2021 by William

Not interested in DIY wearable devices driven by micro-microcontrollers, [Teemu Laurila] Has been working on 3D printed head-mounted computers Put the mature Linux desktop in your field of vision. It may not be as slim and ergonomic as Google Glass, but it makes up for it in terms of raw potential.

This wearable device is equipped with an overclocked Raspberry Pi zero W, an ST7789VW 240×240 IPS display running at 60 Hz and a front camera, providing an excellent low-cost platform for augmented reality experiments. [Teemu] An impressive hand tracking demo has been made, which can pick out the positions of all ten fingers in near real time. The processing must be done on his desktop computer, because Zero is not quite capable of this task, but as you can see in the video below, the whole process works well.

Structurally, the head-mounted device consists of nine 3D printed parts, which are clamped on a pair of standard glasses. [Teemu] Say that parts may need to be adjusted to fit your specific frame, but the design is sufficiently modular and should not take too much effort. He used 0.6mm PETG plastic as the front reflector, and the main lens was pulled from a pair of cheap VR goggles and manually cut into a rectangle.

The evolution of the build is recorded in multiple videos, and it is interesting to see how far the hardware has improved in a relatively short period of time.Original production [Teemu] Looks like he is playing the Borg drone Star Trek, But the latest version seems more useful. We still don’t try to wear it on airplanes, but it hardly appears out of place in hacking scams.
