For our high-school end project in SI (Engineer Science), my friends and I decided to make a Braille printer.
These devices emboss Braille characters on paper, which can then be read by blind people.
Currently, Braille printers cost a lot, thousands of dollars. Other devices for blind people are also excessively expensive (Braille computers, Braille terminals…). In short, you must be rich to be blind, and that's not normal.
Our printer was made in our high-school (machining included, the printer being entirely made of metal) for a total of about $200 of equipment. To get to that price, we use an innovative embossing system, slow, but very cheap to build. The announced printing time of 13 minutes could be enhanced a lot: the system is asolutely not optimized right now.
