A11Y IRL (Accessibility in real life)
summary
Prototype turns JavaScript into a cheap refreshable refreshable brag cells alternative by driving six solenoids per cell from an Arduino Uno controlled with johnny-five. Code maps characters to six-dot arrays, a single cell prints letters live, and a 12-cell rig costs about $40 in parts. Device is open-source, prototypes print from a browser camera feed, and next steps use micro steppers and recycled parts to cut size and power while targeting braille literacy gaps caused by expensive books and hardware.
