it seems like making building an electronic braille display is an interesting side project.
i don't know, 30 units of display thingy that sized similar to mahjong tiles, two buttons to change them to "next line" and "prev line", and maybe a raspberry pi and one sdcard for each book maybe enough to build it?
of course the difficult part is the "display thingy". not sure if they have it in shenzhen.
