Student Innovates 20 Times Cheaper Portable Braille Printer 

Kaviraj Prithvi, an IIT-Guwahati student who lives in Bengaluru, was looking for a solution

to assist the crippled for a college project about a year ago. The 20-year-old realised what the institute lacked

when he visited one of the blind schools in his city and interacted with

the kids and professors there: an affordable way to print textbooks.

Even entry-level braille printers, which are primarily imported, cost between $2,000 and $3,000 (about Rs. 1,50,000 to 2,50,000). 

Due to their limited financial resources, India's special schools are unable

 to import printers. I felt compelled to close this gap and assist the pupils in any way 

 I could after the school visit, says Kaviraj, a final-year physics student.
