Students of Singapore Polytechnics create a text to braille mechanism. via instructables
This project is done by a group of students from Singapore Polytechnic, School of Electrical and Electronics Engineering. We have a total of 5 members in our group, Siti ‘Atikah Bte Mohd Raba’i, Nurridzuan Bin Supardi, Chen Xitong, Toh Lee Ting and Yang Shi Xiang. Our supervisor is Mr Teo Shin Jen.
The concept of our prototype:
The automatic braille is a device to assist the visually impaired to “read” text messages, especially those text messages that are displayed at train stations. This system essentially is an english text to braille conversion with the use of a microcontroller and solenoids.
This project has 2 parts. The input part consist of standard lab issued keypad, that is used to enter english text in the form of ASCII code, the output part consist of 6 solenoids to protrude the ASCII equivalent character in braille. The algorithm “scroll” through the english text character by character and then turning on/off the solenoids to form the corresponding braille character.
Skill level: Basic soldering and C++ programming skills.
Components you’ll need:
6 Solenoids to display 1 braille character (extendable with more solenoids to cover more braille characters)
Rainbow Ribbon Cables
12V DC Voltage Supply
Current for the Solenoid Motors : 1.5A
