NoteTrainer PRO
Trains quickly score reading and piano playing (MIDI-keyboard)
The main purpose of NoteTrainer PRO is developing the ability of quickly reading and playing notes "at sight." The program generates a random sequence of notes in the range selected by the user, and controls the speed and accuracy of their playing. Instead of random notes can be loaded not very complex melodies in MusicXML format and practice by studying them. Input the notes possible not only with MIDI-keyboard, but from the PC-keyboard, as well as using the virtual keyboard. -

Origami Editor 3D
Virtual paper folding program
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 -

Arduino Launch Control System (LCS)
A single rod model rocket launch control system using the Arduino Nano
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. -

Flight Logs
Maintain logs of model rocket flights and your rocket fleet inventory
Update This project has been discontinued due to Microsoft deprecating VBA and VBScript in upcoming Windows updates. Both of these services are needed for Flight Logs to function. Original Description Flight Logs is more than just a database to log your rocket flights. Flight Logs is an in-depth record of your rocket activities. It records your flights plus collects data on events surrounding your flights, and allows you to track how well the rocket performed. The rocket's very beginning is tracked through an extensive Builder's Log. This not only keeps track of the construction process, but tracks any parts ordered. You can even record your 3D prints through the software. And once the rocket starts flying, any maintenance or repairs can also be tracked. Looking to wear the NARTREK Gold? Flight Logs can create the certification packages for Bronze, Silver and Gold, along with the Cadet Mercury Level. -

RTuinOS
The event based Real-Time Operating System (RTOS) for Arduino
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. -
