A low cost BRAILLE display.
Author: Davide Marin (Lumi Industries)
The goal of this project is to create an electronic Braille system that is affordable and can make this technology available to everyone. After initial evaluation, it was clear that thus the design of the individual character had to meet some minimum requirements:
• must use as many parts that are already commercially available
• should be made up with the lowest parts count possible
• custom parts must be easy to prototype, easy to scale up (injection molding)
• power must be not needed to keep the state of the pins
After working on several iterations, I have designed an electronic Braille character with a magnetic retaining system that has a really low parts count, is easy to reproduce or to scale up for production!
