A 13-year-old, Shubham Banerjee, has made a machine to help blind people read. It uses Braille – small bumps that people touch to read letters. Machines that make these small bumps usually cost at least $2,000. Banerjee made his Braille writer from a Lego robot kit. It costs just $350. He called his new device the Braigo – a combination of the words Braille and Lego. It changes electronic text into Braille. A computer or mobile device can print it.

Banerjee designed his Braigo as a science project. The technology giant Intel invested in his machine but did not say how much money. Banerjee also got $35,000 from his father. His father is a computer engineer. He said: "We as parents started to get involved more, thinking that he's on to something and this innovation process has to continue." Banerjee wants many blind people to use his Braille printer.
