A 13-year-old American has made a cheap machine that can help blind people read. People who cannot see can read about at by for from in into of on to using Braille – a system about at by for from in into of on to small bumps that people touch to read the letters. Machines that make these small bumps about at by for from in into of on to words, sentences and paragraphs are very expensive. They are called Braille embossers and usually cost about at by for from in into of on to least $2,000. The American teenager, Shubham Banerjee, made a new Braille embosser about at by for from in into of on to a Lego kit that lets people create robots. It costs just $350. Banerjee has called his new device the Braigo – a combination about at by for from in into of on to the words Braille and Lego. It works about at by for from in into of on to translating electronic text about at by for from in into of on to Braille and then printing it using a computer or mobile device. Banerjee designed his Braigo last year about at by for from in into of on to a school science fair. Since then, he has caught the interest about at by for from in into of on to Silicon Valley about at by for from in into of on to the USA. The technology giant Intel invested about at by for from in into of on to Banerjee's machine last November, but they did not say how much money they put about at by for from in into of on to . Banerjee also got $35,000 about at by for from in into of on to his father to help him start the project. His father works as a computer engineer about at by for from in into of on to Intel. He spoke about at by for from in into of on to his why he gave so much money about at by for from in into of on to his son, saying: "We as parents started to get involved more, thinking that he's about at by for from in into of on to to something and this innovation process has to continue." Banerjee told the AP news agency that: "My end goal would probably be having most about at by for from in into of on to the blind people...using my Braille printer."
