Just like everything else in 2020, the four-day, multi-stage festival of music and art known as Bonnaroo has been cancelled. This would have been [Guy Dupont]’s fifth year making the journey to Tennessee with his friend. Since they couldn’t go, [Guy] decided to build an interactive Bonnaroo mix tape into an 80s clock radio as a birthday present.
[Guy] was able to re-purpose all the original buttons and dials to navigate through the schedule of acts that would have performed across four days and five stages. The conveniently four-way function slider is used to choose the day, and the radio tuning dial selects the stage, complete with delightful static between the positions. The rest of the buttons move back and forth through the scheduled set times, and one will scroll the track and artist name across the 16-segment displays. The snooze button has the honor of being the play/pause button.
All the inputs are controlled with a Feather M4 express, and the music comes through a DFPlayer Mini. We love that [Guy] was able to repurpose the analog tuning dial by coupling it to a slide potentiometer that fit perfectly in a slot on the underside of the plastic. Stay tuned for a great video that starts with an explanation and demo and then goes into the build.
Though the utility of the clock radio may have been supplanted by cell phone alarms and doomscrolling, that just means that there are theoretically more of them to gut and turn into other things, like this Fallout-inspired luggable Pip-Boy.
