Building An Accessible Smart Guitar for the Deaf, Blind and Mute
summary
A prototype called Chord Assist prototype embeds a Raspberry Pi, USB mic, Pimoroni 4‑char display, Firebase storage and Raspberry Pi + Dialogflow conversational backend to teach guitar chords by voice or buttons; pico2wave TTS plays audio, images stream from Cloud Storage, and a bank of braille solenoids behind a relay-driven power board renders braille. The guitar cost about £80 secondhand, reuses a £35 Pi, serves blind, deaf and sighted users, and the build works as a usable demo.
