A 13-year-old American has made a cheap machine that can help blind people read.

The blind canreadby using Braille – a system of small bumps (隆起物) that the blind touch to read the letters. The machine that makes these small bumps usually costs at least $2,000. It is called Braille writer. The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo – a combination (组合) of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine.

Banerjee designed (设计) his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer (工程师) at Intel. He spoke about why he gave so much money to his son, saying:”We as parents started to be interested more, thinking that he's on to something and this invention has to continue.” Banerjee told the AP News: “My dream would probably be having most of the blind people…using my Braigo.”

      Last year, I worked in a middle school near my mother's house, and I stayed with her for a month. During that time, I helped her do some

 housework and buy some food.

      After the first week, I noticed that the food was eaten up very quickly. Then I began keeping an eye on my mum. To my surprise, I found

that she would put some of the food into a paper bag and go out with it at about nine every morning. And finally, I decided to follow her. I saw her taking the food to the street children. She would also spend a lot of time talking and playing with them.

      One day, I talked to a neighbour and found out that my mum was well-known in the area. The children were very friendly with her and even thought of her as their own mother. Then it hit me – why wouldn't she want to tell me about it? Was she worried that I would stop buying food if I found out?

  When my mum got home, I gave her a big hug (拥抱). I told her she didn't need to keep it a secret from me. And she told me something about the children. Some of them lived with an old lady in a small house. Others slept on the street. For years, she was helping the poor street children by giving them food. After she told me everything, I was so moved by how selfless (无私的) she was. She helped others in need. As her son, I was so proud of my mum.

      I continued to buy food for my mum after that. But I always added one more bag for her other children.
