Wave (Sound) to OpenSCAD Bracelet Converter by pgreenland Mar 10, 2013

Description

Convert a message recorded in Microsoft Wave format into a 3D printed bracelet / necklace / thing.

Given a wave file the python script included with this thing will digitize it into a series of concentric circles forming a bracelet like design, creating an OpenSCAD script.

The OpenSCAD script may be used to view the waveform arranged as a bracelet design as well as preparing trays of circles ready for printing, all numbers to allow for assembly.

It's been a while since I had time to play with my printer, or even look on thingiverse :-( - Upload a pic of a printed one if you have a go, would love to see it. :-)
Cool, just discovered this coincidentially. I'm the designer of the instructable you were refering to. I will definetely try this out!
Now someone needs to invent a player for the prints.

Instructions

  1. Record a message using you favourite audio editor in Microsoft Wave 16-bit PCM format.
  2. Execute python script passing wave and scad file names.
    python wave-to-openscad.py input.wav output.scad
    Note: Many additional options are available to control aspects of the bracelet generated such as minimum / maximum sizes of circle, the size of the hole in the centre as well as printer bed dimensions for tray layout. Also given a stereo audio file only the left channel will be used.
  3. Load scad file in OpenSCAD, changing set_tray variable from -1 (view) from 0-n (trays) to export and print bracelet components.
  4. Print and assemble using OpenSCAD background numbers as a guide.
