Open Source Java Hobbies Software

Data Crow is an open source collection manager for movies & video (DivX, MP4, MKV, etc.), TV series, books (and eBooks), images, board games, comic books, games & software, and music (MP3 and other audio files). Besides these built-in modules (which you can customise to fit your needs) you can create entirely new ones. Want to catalogue your stamps, equipment, wine, or anything else? Data Crow makes it possible. Your collection is accessible the way you prefer: as a stand-alone desktop application, in server-client mode for shared access across multiple users or devices, via the web client in any browser, or on the go with the Data Crow Reader App. The app synchronises with your Data Crow installation and works fully offline. Private. Offline. Completely personal. The Data Crow way.

Grimmory is a self-hosted digital library management platform designed to help users organize, read, and manage their entire book collection in a centralized and fully controlled environment. As the successor to Booklore, it expands on the idea of personal knowledge ownership by allowing users to store and interact with books without relying on third-party cloud services. The platform supports a wide range of formats, including eBooks, PDFs, comics, and audiobooks, making it versatile for different types of media consumption. It includes a built-in browser-based reader that allows users to read, annotate, and track progress directly within the application. Grimmory also emphasizes automation through features like metadata enrichment and automatic file ingestion, reducing manual effort when managing large collections. Multi-user support enables separate libraries, preferences, and reading progress for different users within the same instance.

Origami Editor 3D is an advanced paper folding simulator. It uses a what-you-see-is-what-you-get interface and operates with a geometric abstraction of the Yoshizawa-Randlett system. Anything from a simple airplane to John Montroll's omega star can be folded in this editor. Origami files created with the program preserve the entire folding process, and they can be exported as folding diagrams in PDF, animated GIF files, or even as standalone Java programs displaying the origami in a 3D viewer when opened. The main purpose of this program is designing origami, but if you only want to learn how to make some origami figures, there is a set of built-in example files that can help you. Currently, there are 34 example figures available. Please note that this project was created for fun and still is a work in progress. The Discussion forum is open for anyone who wants to report a bug or suggest a new feature. User Guide: http://origamieditor3d.sourceforge.net/userguide/en/index.html
