the braille project

Yesterday, I designed a Node-based program to generate a 3D mesh file programmatically from the input text to create a braille message.

The concept is easy enough to grasp. Braille is a simple combination of raised dots. If we can know that combination, then it should be easy enough to design a 3D CAD object which uses tiny spheres to render the scene.

But I didn’t want to laboriously design this in Autodesk Fusion 360 and I’m sure few people would. Everything has to be precisely placed and that’s just too much manual work. Even if you did, it’s not very easy to maintain. If you did catch an omission, just think of all the work you’d have to do to move things around! I’m relatively certain that this is currently how people create braille-based printouts as seen on an ATM machine, for example.

So yesterday, I designed and created a program for doing this. Generating the STL file was then painless and took less than a second. Printing it then took five hours so I got to see it as a finished part this morning.
