Those are my Open Source x-plane plugin projects. They're written in python which is great cause they can be run on all platforms supported by x-plane. They require a Python 2.7 installation in your system and Sandy Barbour's X-Plane Python Interface. Osx and most Linux distributions come with python installed so there's only need to install Sandy's plugin.
All plugins are released under the GPL license, the code is available to learn, extend its features and modify-it to fit your needs. You can browse my code projects and contribute at github.
