The display is a wooden box that sits on top of an antique radio. It has a button, and when the button is pressed a short recording of an old radio broadcast for a hockey game is played.
How we did it
The electronics are enclosed in a birch plywood box, with power and speaker leads running out the back of the box and then down behind the radio so they are not easily visible.
There is a single button that is accessible by visitors, it is connected to a Raspberry Pi Pico microcontroller, which monitors the button and when a button press is detected, it selects a random track (based on the number of tracks on the SD card) and then sends serial commands to a DFPlayer Mini board to begin playing.
The DFPlayer Mini board's output is connected to a 3W paper speaker that has been put inside the radio to make it appear that the sound is coming from inside the old radio chassis.
