12-Year-Old Builds Lego Braille Printer

An anonymous reader writes "Shubham Banerjee, a seventh grader in California, has developed a braille printer made from a $350 Lego Mindstorms EV3 kit and some simple hardware. He calls the science fair project the Braigo. 'The Braigo's controller is set up to scroll through the alphabet. You choose a letter and it prints it out with tactile bumps on a roll of calculator paper. The print head is actually a thumbtack, which Banerjee settled on after also testing a small drill bit and a mechanical pencil. The first prototype isn't terribly fast, but it proves the concept works. Banerjee is working on improvements that will allow it to print full pages of text.'"

Braille Legos

So it looks like his device is a braille paper printer (Which is pretty darn cool), but I wonder if something like a smaller version of Legos could be used to make "eraseable" braille type.
