I am always tinkering with something. Since 2000 I have administered my own Linux web server and get a twisted enjoyment out of rebuilding it every few years. The latest ongoing effort has been to automate building out my server onto Amazon EC2 using Chef.
My open-source projects are available on GitHub.
Customizable nutrition journal. Uses the USDA nutrition database and user submitted foods. Allows the user to customize which nutrients and additional statistics they wish to track and generate reports.
Bytes for Health uses Nutritionix for some of it s nutrition information. This is the .NET client library I wrote for their API.
Used the XNA game library to create a cross-platform game (OMG Ponies!). My first game engine: game loop, sprites, backgrounds, cross-platform input handling and collision detection. As always my total lack of graphic design skills holds back my budding game development career! :-)
