 Guitar Tuner for the Blind Hack


Guitar tuners are quite common these days. Only problem is that they use displays or LEDs to indicate how the tuning process is going. Sam from J44 Industries made a guitar tuner that a blind person can use for a charity called Remap. His design starts with an off the shelf guitar tuner, only problem with this one is that it used LEDs for visual feedback. He used an arduino to monitor the state of the LEDs and generated audio feedback using an earbud for the user to hear the process. He has some smart audio cues that lets the person know when they are getting close to having the string tuned so that you can adjust the amount of peg turn accordingly.

    Seems to me that we should redesign guitars so that they could make their own auditory feedback when they were out of tune… Nah, I get it. A blind musician in a noisy (stage) environment needing to tune to a standard reference so that they would be in tune with the rest of the band probably would benefit from this thing.

    Better to use an electric shock, but some musicians might disagree…
