Santa Clara high school student Shubham Banerjee has reinvented the Braille printer thanks to his love of Lego. His start-up company BRAIGO has attracted funding from Intel, but as Shubham is only 13 his mother Malini Banerjee is CEO. Shubham's model is set to be more affordable than existing products, and he's hoping to have a first prototype for blind organisations to try out in the next few months.
