I want to create a Low cost Braille Line printer with ESP32 (WiFi) using a single Solenoid / Servo.
The idea is to go print the 1-3 dots for the "whole line" then a linear movement to print the 2-5 & subsequently to next line. What will be the BoM and challenges for this project? Is there any OpenSource git for this? This will be for a blind school for kids. The end-goal is to supply a PDF and then the braille system takes over to convert to braille dots and then finally print it out.
