LEGO braille printer

12-year-old builds low-cost LEGO braille printer

12-year-old Shubham Banerjee, a seventh grader residing in California, contemplated the issue of braille printers as a science fair project and decided there must be a better way.  Armed with his apparent genius knowledge, he came up with a solution using LEGO Mindstorms' EV3 kit along with a few bucks worth of hardware from Home Depot, bringing the original cost of a braille printer from the $2,000 range down to about $350.
