Yes, I think the most common designs use an individual solenoid for each braille dot. And then the "small scale" of the available market for them keeps it from being mass manufactured to the point of real affordability. Or, at least that was very much the case in 2011 when the article was written.
I agree with you about the gears. Looking at it now I wonder as well if some tried-and-true belts and pulleys from the ubiquitous 3D printer designs could make that motion work.
Ooh, that's true! It's pretty much the exact same problem.
