RumbleRail – The Standalone & Modular Floppy Disk Jukebox

RumbleRail – The Modular Floppy Disk Jukebox

Each floppy drive is equiped with two bright RGB LEDs (rrled) illuminating the floppy cases according to the currently played tune – a simple but actually quite pretty visualisation of the music being played.

The overall setup is completly modular. Each floppy is connected to its own floppy driver (rrfdc), which in turn speaks I²C with the main board (rrcmd). On power-on the main board auto-discovers the connected floppies and adjusts the software to utilize the available drives. In theory the amount of floppies connected to RumbleRail is only limited by I²C address/bus restrictions.

The most important feature of RumbleRail is the ability to run standalone. After being powered-on, the main board scans the hotswapable SD card (rrsdc) and lists its content on the display. The user can browse through the selection using the rotary encoder and, once a song is selected, the main board decodes the MIDI file and streams the notes to the floppy drivers.
