Arduino ☛ Novel mechanism makes refreshable braille displays practical
Both display types rely on electromagnets to push up pins below the dots. But it wouldn’t be feasible or cost-effective to include hundreds of electromagnets in a display like this, which is why MagnePins has a kind of “scanning” mechanism to actuate the pins column-by-column in quick succession. That mechanism slides underneath the display while the pins ride in special channels. A staggered line of pistons, actuated by 24 electromagnets, either remain low or protrude upward to change the positions of the pins as they move overheard.
