Overview
Pluralsight Floppy is an open-source printed circuit board by jzkmath, from the jzkmath/Arduino-MIDI-Floppy-Drive-Instrument repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 101.6 × 53.3 mm with 34 parts on 96 nets, routed with 425 tracks and 0 vias.
Its parts include 28 connectors, 3 resistors, 1 IC and 1 diode. It belongs with the audio and music and robots and motor control boards of this library.
README
README.mdArduino MIDI Floppy Drive Instrument
This is the design files for an Arduino Floppy-Drive controller that is MIDI Controlled. It is a combination of the MIDI Stepper Synth V1 and Moppy Software.
The core method for controlling the floppy drives is the use of a non-blocking delay. If you want to make a stepper motor play at a certain frequency, simply pulse the pin at that specified frequency. In this case however, the position of the drive head is important, so we simply need to track the position and reverse direction when that point is reached.
Refer to the schematic for pinouts. The header pins connect to the IDE connector of the floppy drive and maintain the ground reference.
Look at this pinout:
We need to connect "drive select" together (Pins 11 and 12) to enable the drive and then connect the Step and Direction to the Shield.
PINOUT:
12 - Drive Select (Enable)
11 - Drive Select Ground
18 - Direction
17 - Direction Ground
20 - Step
19 - Step Ground
NOTE:
There is a two pin header (J14) that is the programming jumper. The jumper should be installed here and removed when the Arduino is being programmed. This is because the MIDI Rx line is also use to program the Arduino when its being flashed.

Questions
How big is the Pluralsight Floppy PCB?
It measures 101.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pluralsight Floppy use?
34 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pluralsight Floppy KiCad files?
From the jzkmath/Arduino-MIDI-Floppy-Drive-Instrument repository on GitHub, at the commit this page was made from: the board is KiCAD/Pluralsight_Floppy/Pluralsight_Floppy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pluralsight Floppy design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
