Design woodwind instruments and make them with a 3D printer or CNC mill.
Project description
Demakein
========
Paul Harrison - pfh@logarithmic.net
Demakein is a set of Python tools for designing and making woodwind
instruments.
This generally consists of two stages:
- The "design" stage is a numerical optimization that chooses the bore
shape and the finger hole placement, size, and depth necessary for
the instrument to produce the correct notes for a given set of
fingerings.
- The "make" stage takes a design and turns it into a 3D object, then
then cuts the object into pieces that can be CNC-milled or 3D-printed.
Demakein can either be used via the command "demakein" or as a
library in Python. Demakein has been designed to be extensible,
and I hope you will find it relatively easy to write code to
create your own novel instruments. You can either create subclasses
of existing classes in order to tweak a few parameters, or create
wholly new classes using existing examples as a template.
Requirements
============
Python 2
- Linux:
Use your package manager to install Python 2 and pip.
- Windows:
Follow these instructions:
http://docs.python-guide.org/en/latest/starting/install/win/
- install python 2 using the MSI package
- install distribute using the linked script
- install pip using easy_install
I'm sorry this is so involved.
The "design" tools require nesoni. They should work on all platforms that
Python runs on.
- nesoni
pip install nesoni
The "make" tools additionally require CGAL and associated paraphenalia.
I have only tested this on Linux.
- g++
- cmake
- CGAL
apt-get install g++ libcgal-dev cmake
- cffi
pip install cffi
Installation
============
Easy way
pip install demakein
From source, download and untar tarball then
python setup.py install
You can then run program by typing
demakein
or
python -m demakein
Example
=======
Create a small flute:
demakein design-straight-folk-flute: myflute --transpose 12
demakein make-flute: myflute
Files are created in a directory called myflute.
We've just made STL files for 3D printing. How about if we want
to CNC-mill the flute?
demakein make-flute: myflute --mill yes --open yes --prefix milling
