Californian seventh grader creates a working braille printer for only $350.

Aspiring young talent Shubham Banerjee and his recent science fair project demonstrate that this 12-year-old California seventh grader is destined for great things. He designed a low-cost braille printer using a $350 Lego Mindstorms EV3 kit and a few bucks worth of hardware from Home Depot. The result is a fully functioning system that is comparable to current market models, but at a fraction of the cost.

The BRAIGO v1.0 includes a base reference model known as Banner Print3R and new software to print letters A-Z. Several trial and errors were made before Banerjee could get one to successfully print out letters in braille.
