- Braille Vision is a project aimed at improving media accessibility for the visually impaired by converting text into braille.
- The device uses a Raspberry Pi with OCR (tesseract) to read text from images and an Arduino to control a braille display pad.
- Key components include Raspberry Pi 4/5, Arduino Uno, solenoids, MOSFET transistors, and a 3D-printed braille display pad.
- The project involves learning braille, setting up Raspberry Pi, designing and 3D printing components, and assembling electronics.
- The final device allows users to take a photo of text, convert it to braille, and scroll through the output using a rotary encoder.
