Good to see them doing something useful, but it’s hard to imagine that there is not a braille-embossing machine out there to do this automatically.
I have a blind friend. I called a local braille transcribing service to see what it would cost to get my book set in braille. $3000+. Braille printers cost thousands. I'm waiting for 3D printers to be used to print braille and bring the price down.
