12-year-old builds low-cost Lego braille printer.

Shubham Banerjee, a California seventh grader, is one of those kids whose heart and mind extend well beyond his own life and into the the wider world beyond. For a science fair project, he contemplated the issue of braille printers, which can cost upwards of $2,000, and decided there must be a better way.

The better way he came up with involved the clever use of a $350 Lego Mindstorms EV3 kit along with a few bucks worth of hardware from Home Depot. He took a basic, preexisting pattern for a printer and reworked it with new software and hardware enhancements to print out letters in braille. The result is called the Braigo.
