About the Arduino-MIDI-Floppy-Drive-Instrument PCB

Arduino-MIDI-Floppy-Drive-Instrument is an open source AVR/Arduino PCB design by jzkmath, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 101.6 × 53.3 mm, with 33 components from 26 distinct parts.

Its main chip is the Arduino_1pin, from the AVR/Arduino family. Other key parts include the 6N138. By type, the board carries 28 connectors, 3 resistors, 1 IC and 1 diode.

It belongs with the audio, robotics & motion and test & measurement designs in this gallery.

From the project

Modified version of the Stepper Synth V1 and the Moppy Software that uses an Arduino Mega to control 24 Floppy Drives

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.

Arduino-MIDI-Floppy-Drive-Instrument: common questions

What microcontroller does the Arduino-MIDI-Floppy-Drive-Instrument use?

The Arduino-MIDI-Floppy-Drive-Instrument is built around the Arduino_1pin, from the AVR/Arduino family.

How big is the Arduino-MIDI-Floppy-Drive-Instrument PCB?

The Arduino-MIDI-Floppy-Drive-Instrument measures 101.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino-MIDI-Floppy-Drive-Instrument?

33 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Arduino-MIDI-Floppy-Drive-Instrument design files?

From the jzkmath/Arduino-MIDI-Floppy-Drive-Instrument repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Arduino-MIDI-Floppy-Drive-Instrument design in my own project?

Yes, under the terms of its GPL-3.0 license, which jzkmath chose for the repository.

Can I test firmware for the Arduino-MIDI-Floppy-Drive-Instrument without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
