Stuff Made Here builds a device that lets a blind person perceive their surroundings by touch, using an iPad's lidar and a mechanical tactile display driven by motors. The video walks through the build and the limits he hit.
HN admires the maker's engineering and cites it in accessibility discussions, especially for the limits of sensory resolution versus perception.

This guy is a legend. Awesome videos. A few of them seem productizable in a way most DIY-er videos don't, albeit in a limited run capacity. He made a iPad lidar to "braille" converter that was really impressive, and I'm hopeful someone picks up the work. [VIDEO]
There was a Youtuber that made a device like this with the lidar from an iPad and a 3x3 grid of dots to detect obstacles. The problem he ran into was sensory resolution vs. ability to perceive that resolution. (Unsurpisingly) your eyes are unparalleled for picking up visual resolution. [VIDEO]
Would it be possible to use fewer motors to control more pins? 'Stuff Made Here' made a 12-point display using two motors. [VIDEO]
