I was quite surprised to find out how expensive assistive technology is. A mechanical braille embosser cost over a 1000$USD and an electric goes from 3000$ up to 5000$. I tough about making one for a friend but I couldn’t find a DIY version, so I decided to make one myself. This isn’t, by any means, a finish product. By making the machine an open source project, I am hoping others will improve the design. In a near future, with the help of others makers, OpenBraille will reduce the cost of these printers and it will allow anyone with a visual imparity to read and write. So, if you know someone, if you are a maker, if you are curious or if you want to help out, please feel free to follow this tutorial and help me built a community around OpenBraille.
The encoder is pretty much the heart of the embosser. Most of the commercial machines emboss the dots by impacting the sheet. Because it’s harder to build a precise machine out of 3D printed parts, I designed a different system. Instead of impacting and applying all the energy in a single hit, OpenBraille uses a physical encoder and a roller. This way, the embossing is gradually done and the parts can be easily printed.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
