I transformed an old General Electric clock radio such that - rather than dial into an AM/FM radio station, you choose a day/stage/set and listen to the music that you would have heard if you were there.
I leveraged most of the original hardware, but I created a new display, face-plate and labels to A) highlight the new functionality and B) fit the festival vibe!
Step 1: Use the four way switch to choose between Thursday, Friday, Saturday, or Sunday.
Step 2: Use the old radio dial to move to a stage (yes, the stage names are confusing: This, That, The Other, Which, and What)
Step 3: Use the clock set buttons to scroll between set times.
Step 4: Hit the play button, jam out.
