A 4 line x 32 character Braille display and keyboard for the Blind.
Project in progress by Sean Kelleher
The trouble is the piezoelectric Braille cells cost about $60USD each. that means the part cost alone for a 32 Character Braille display is on the order of $2000. The point of this project is to find a less expensive Braille Cell. With the technology I am testing a row of 32 cells will cost around $150. Yes other than the inexpensive Braille cell all other aspects of this project have been done before.
