LPub3D is an Open Source WYSIWYG editing application for creating LEGO® style digital building instructions. LPub3D is developed and maintained by Trevor SANDY. It uses the LDraw™ parts library, the most comprehensive library of digital Open Source LEGO® bricks available (www.ldraw.org/ ) and reads the LDraw LDR and MPD model file formats. LPub3D is available for free under the GNU Public License v3 and runs on Windows, Linux and macOS Operating Systems. LPub3D is also available as a Linux 'no-install', multi-platform AppImage. Portions of LPub3D are based on LPUB© 2007-2009 Kevin Clague, LeoCAD© 2025 Leonardo Zide, LDView© 2025 Travis Cobbs & Peter Bartfai and additional third party components.

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

Marc's Awesome Name Generator is a Java based library to allow the easy and fast generation of random first, middle and last names based on user-definded criteria, such as culture of origin or contained letters.

Strum aims to improve your musical skills on stringed instruments; learning scales, chord construction, and how to find them on various instruments with many tunings.

This is a single rod model rocket launch control system. The system utilizes the Arduino Uno/Nano to report on local weather conditions (temperature, humidity, barometric pressure). The system also provides a 10-second countdown when the fire button is pressed. The system meets and exceeds the NAR Safety Code standard for model rocket launch systems as it incorporates a removable key to block the flow of power to the launch pad. It incorporates an additional two-button safety system to ensure that a launch is conducted exactly at the desired time. This release marks Version 1 of the system. It is designed to be modular so that it can be easily modified in the future. This project makes a great entry into electronics, Arduino and model rocketry. As such it is ideal for use in schools and youth organizations.

NOTE: The Astrolabe Generator has moved: The Astrolabe Generator and related projects have moved to a new location. Find us on Github at: https://github.com/wymarc This program will generate a set of PostScript (EPS) files for the front, back, rete and rules of an astrolabe for a given latitude. Additional related quadrant tools are also available. Version 3.0 moves the code to Java. Program is now an executable Jar file.

This application is made as a project to measure the Speed of your brain. How fast is your brain as compared to other humans. As you all know the computers processors speed is measured in the MHz or GHz, as there are some standards to measure the speed of them. Bur unfortunatly there is no standard to measure the speed of human brain. So here comes the Brain Speed Test!

Building a mobile app capable of running on multiple platforms can be a daunting task. Different operating systems, screen sizes, offline capabilities and more can be a challenge. A growing number of developers are opting to build their apps in cross-platform HTML5 code that can be compiled into native apps that can be sold in app stores and markets.

Introduce any song from your computer and the lyrics and practice your English (or any other language), filling in the suggested gaps. An embedded dictionary will help you understand every word. It's funny!

RTuinOS, the event based Real-Time Operating System (RTOS) for Arduino, is now hosted at SourceForge. In this revision, 1.0, the event concept has been generalized. Events can now be broadcasted events, semaphores or mutexes. This permits to implement all the usual inter-task communication patterns. Please refer to the user guide and the diverse code samples for details. The second technical change is a complete revision of the makefile. It has been improved in many aspects and it now supports three host operating systems; the RTuinOS samples (as well as your applications) can be built under Linux, Windows and Mac OS. RTuinOS 1.0 is distributed as setup (a ZIP archive), which contains all source files and the complete documentation, also with source files. Building the samples can be started immediately after unzipping and setting a single environment variable. Thank you for your kind interest in RTuinOS.
