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]
Read original comment ↗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]
Read original comment ↗Would it be possible to use fewer motors to control more pins? 'Stuff Made Here' made a 12-point display using two motors. [VIDEO]
