Inexpensive handheld braille writer made by students – “To help provide a low-cost communication tool for blind people, undergraduates at The Johns Hopkins University have invented a lightweight, portable Braille writing device that requires no electronic components. For a class called Engineering Design Project, four mechanical engineering majors were asked to produce such an instrument that would cost less than $50 each” [via] – Link.

Conceptually very similar to some mechanical braille typewriters
Would seem to me that it would work better at doing indentions instead of piercings if the pins just barely went past the housing when extended, that way you could press the housing flush against a page and “type” while scrolling left and right.
Best Make for the Blind I’ve ever seen was a converted dot matrix printer, a brass head with pins was fitted ontop of the print head and script was used to convert a textfile to print in braille, and backwards.
