it seems like making building an electronic braille display is an interesting side project. This already fell off the front page but I am actually working on exactly that project right now. The inspiration was standing around with my kid, seeing some braille and decoding it. The cost of the current systems is associated with the volume of hard tooling and assembly work necessary to create the precision lever assemblies based on 1970s piezo technology. Therefore, the initial R&D goal is to determine whether it may now be possible to achieve similar outcomes using alternate approaches to the actuation problem. Many people have tried but it seems all have failed to achieve the necessary combination of alternate actuation, spatial density and manufacturability within a low cost design goal.
