Braille Keyboard Key Covers stv-is-it
Use an old keyboard and glue the Braille covers with a drop of silicone.
The Braille specifications were found here:
For those symbols that are obtained with the SHIFT key, this additional element must be added between the key and the Braille key cover.
This element increases the height of the Braille key cover by 4 mm (0.157 inch) and makes the blind person perceive a difference to the touch compared to the other buttons to remind him that he must also press the Shift button.
