Lyra is a front-end to the Music Player Daemon (MPD). Based loosely on the Creative Media Source software, it has the aim of supporting large collections of albums and artists. Other interesting features are the implementation of a local cache of the music library using an SQLite database, increased speed, and flexibility. In addition, Lyra supports integration with the Last.fm service, which includes "Scrobbling" and album cover art.
annoyme is a program that plays a sound effect every time you hit a key on your keyboard to give you the feeling you are using a real typewriter. This can be used to impress colleagues with your typing skills or just for sentimental reasons. It supports various sound input methods, as well as multiple output libraries like ALSA or AO. Most importantly, it is also possible to add more sound themes. Currently, only input for XEvIE (on an X Server) is supported.
HeeksCNC is a CAM (Computer Aided Manufacturing) add-on module for HeeksCAD. The user can add machining operations. These can then be output to NC code. The NC code is then shown as red and green lines on the screen. The NC code is generated using Python script, so it can be configured for different machines. HeeksCNC uses pycam for the "Zig Zag" operation, libarea for the "Pocket" operation, and libactp for the "Adaptive Roughing" operation.
HeeksCAD is a CAD application. It can import solid models from STEP and IGES files, draw construction geometry and lines and arcs, create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Solids can be modified using blending or boolean operations. Models can be saved as IGES, STEP, and STL. The 2D geometry can be plotted with a printer or to HPGL. DXF files can be imported and exported; lines, arcs, spline, ellipses, and polylines are supported. SVG import has similar capabilities. It is possible to make Add-In modules. The HeeksCNC project provides a CAM add-in, and HeeksPython provides a Python console.
Scalpel is an audio editor for Linux. It aims to provide a simple-to-use and easy-to-extend audio editor. Scalpel still has some rough edges but is quite usable. Scalpel uses PyGTK for the user interface, Numpy for the internal processing, ALSA for the audio playing, and libsndfile for reading and writing files. A minimal part of the code is written in Cython for better performance.
