Music box tune tracker. Create or import a tune and turn it into a record for the Fisher Price Record Player toy

Music Box Tune Tracker uses the same file format (.fpr) from Fred Record Player available at https://www.instructables.com/id/3D-printing-records-for-a-Fisher-Price-toy-record-/

For usage, use the --help argument. Some arguments are available only if some optional package are installed.

Prerequisites

This software uses Python with the Curses library for the User Interface.

Optional Dependancies

• Wav playback is the more easy and is recommanded.
• Midi playback will add extra functionalities but will require a little more configurations.

WAV audio backend

pip install playsound

Midi audio backend and extra functionalities

For more informations about using midi as an audio backend and import/export from midi files, see midi.md.

Convert .fpr to .scad

.fpr file can be converted to .scad file by using the src/fpr_to_scad.py script

usage: fpr_to_scad.py [-h] [--fpr FPR] [--fprbis FPRBIS] [--scad SCAD]
                      [--thickness THICKNESS]

optional arguments:
  -h, --help            show this help message and exit
  --fpr FPR             name of fpr file
  --fprbis FPRBIS       name of fpr file for second side
  --scad SCAD           name of scad file to output
  --thickness THICKNESS
                        thickness in mm. Defaults to 3 if one
                        side or 5 if two sides

Convert .scad to .stl

the scad file can be use with OpenScad to create a .stl file to 3D print the record.

Open a scad file then menu Design/Render (F6) then File/Export/Export as STL (F7)

How to print the name of the song on the disc

The Write.scad and it's dependancies are required to have the title of the tune written on the disc.

Move the files under writescad (updated version from https://www.thingiverse.com/thing:16193) where OpenScad can find it.

Thanks

• FredMurphy to have created and shared "Fred Record Player" source code, it was of a great help, notably to implement the export to scad feature.
