12-year-old creates an affordable braille printer with LEGOs

For those of you who thought baking soda volcanoes made for a pretty sweet science fair project, 12-year-old Shubham Bannerjee’s entry will absolutely blow you away. It’s an actual working braille printer that was built with about $350 worth of Lego that runs on open source software. Braille printers aren’t exactly cheap. One that can handle standard paper can still cost more than $2,000 today. Shubham’s goal was to create something that was affordable enough that could fit into the average home or classroom budget.
