Open Source C Hobbies Software

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.

IMG4DC is a tools package containing two utilities to generate selfboot disc images for your Sega Dreamcast: cdi4dc, designed to make Padus DiscJuggler (CDI) images and mds4dc, designed to make Alcohol 120% (MDS/MDF) images. A selfboot image is a disc image format specially prepared to boot on your Dreamcast. In clear, by burning a selfboot image to a standard blank CD-R, the software containted into this disc image will run onto your Dreamcast, as a legit game disc, without any modchip or other hacking device. To use this software package, you must have mkisofs from the cdrtools project. This tool will create the ISO image needed by img4dc.

This project contains useful software tools to create a NBTV (Narrow Band Television) video source (+audio, and optionally with color) on a classical 2-channel PC audio output. It also includes a document on a hardware example explained in details, as well as how to use software tools.

This is an open-hardware one-button time-lapse camera timer initially developed for a Canon 400D Digital SLR camera. It can be used to take photographs at intervals from 1 second to 65535 seconds (approximately 18 hours). Uses a PIC microcontroller.

The Image Compare project provides two applications. The Image Compare application (imagecomp) is a tool to aid the visual comparison of two coin images. The Image Mask command line application prepares coin images for publication.

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.

ImproK est un logiciel permettant l'affichage de scores, avec compte-à-rebour. Les règles d'affichage sont adaptées à un match d'improvisation, mais peuvent facilement être modifiées pour correspondre à d'autres genres d'événements, par exemple des rencontres sportives.

The Model Railroad System is a software package that can help you run your railroad. Download the Model Railroad System now and operate your layout, from running trains to working your signals and switches. This software package has support for a network of Bruce Chubb CMR/I USIC, SUSIC, and/or SMINI nodes and/or a network of Lenz’s XPressNet DCC nodes. It now supports Azatrax USB-connected Model Railroad Detectors. Software to create switch lists for freight car forwarding and creating timetables for your railroad are included. There is software to help with photographing of your trains and to compute the correct value for those pesky dropping resistors for LEDs and/or incandescent lamps. If you have a model railway, large or small, this software package will help you out.

You can code to morse or enode from morse in a simple way. It's written in ANSI C, the source code is redy to be built for unix based systems. There can be bugs in it, but it does the work. I recommend the source code for those who are learning C.

Numismatic is a simple Web-based application that may be used for storing and retrieving coin-related information. The software supports multiple users. The official source repository is located at https://github.com/textbrowser.

The small PSoC4 device from Cypress semiconductors contains an ARM M0 CPU, 32k flash and 4k sram and *LOTS* of interfaces. The project implements an interface to the RC sum-signal and controlls the 4 motors.

Open source display and controller for digital slotcar racing. Its purpose is to parse, interpret and show as much of the digital information that travels throught the lanes as possible.

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.

RobotSee is a language as easy as Basic, with the power of C. The RobotSee VM is a virtual machine that will run on anything from a small 8bit machine all the way up to a linux/windows class machine.

Command-line tool to check ADFs (Amiga Disk Files) for errors and viruses. A binary is included for Windows users; Linux users are advised to compile the application themselves. Might also compile under plain DOS; but BE WARNED! When you scan files already renamed by the TOSEC standard, consider that file names may become insanely long in no time. --UPDATE OCTOBER 2014-- This project is currently suspended! I can't currently find the time to fix/update anything with this program and hence it must be considered 'on hold' at the moment. Sorry for the inconvenience.
