The system call intercepting library provides a low-level interface for hooking Linux system calls in user space. This is achieved by hot-patching the machine code of the standard C library in the memory of a process.

Horizon EDA is an Electronic Design Automation package supporting an integrated end-to-end workflow for printed circuit board design including parts management and schematic entry.

minicom is a serial terminal emulator.

This package contains all part definitions that are required for Fritzing app.

mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP).

Harminv is a free program (and accompanying library) to solve the problem of harmonic inversion — given a discrete-time, finite-length signal that consists of a sum of finitely-many sinusoids (possibly exponentially decaying) in a given bandwidth, it determines the frequencies, decay constants, amplitudes, and phases of those sinusoids.

Candle is a GRBL controller application with a visualizer for G-Code, the CNC programming language.

Supported functions include:

• Controlling GRBL-based cnc-machine via console commands, buttons on form, numpad.

• Monitoring CNC-machine state.

• Loading, editing, saving and sending of G-code files to CNC-machine.

• Visualizing G-code files.

PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It is compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.

XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. It consists of a collection of menu-driven routines which perform various useful functions such as:

• Viscous (or inviscid) analysis of an existing airfoil

• Airfoil design and redesign by interactive modification of surface speed distributions

• Airfoil redesign by interactive modification of geometric parameters

• Blending of airfoils

• Writing and reading of airfoil coordinates and polar save files

• Plotting of geometry, pressure distributions, and multiple polars

OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and macOS. Unlike most free software for creating 3D models (such as the famous application Blender), OpenSCAD focuses on the CAD aspects rather than the artistic aspects of 3D modeling. Thus this might be the application you are looking for when you are planning to create 3D models of machine parts but probably not the tool for creating computer-animated movies. OpenSCAD is not an interactive modeler. Instead it is more like a 3D-compiler that reads a script file that describes the object and renders the 3D model from this script file. This gives you, the designer, complete control over the modeling process and enables you to easily change any step in the modeling process or make designs that are defined by configurable parameters. OpenSCAD provides two main modeling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As the data exchange format for these 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.

This package includes simulation models for an induction motor, a synchronous reluctance motor, and a permanent-magnet synchronous motor. The motor models are simulated in the continuous-time domain while the control algorithms run in discrete time. The default solver is the explicit Runge-Kutta method of order 5(4) from scipy.integrate.solve_ivp.

Scikit-rf, or skrf, is a Python package for RF and Microwave engineering.

LibrePCB is Electronic Design Automation (EDA) software to develop printed circuit boards. It features human readable file formats and complete project management with library, schematic and board editors.

Cutter is a reverse engineering platform powered by rizin. It aims to be an advanced and customizable reverse engineering platform while keeping the user experience in mind. Cutter is created by reverse engineers for reverse engineers.

This package provides platfrom-independent types, macros and a fallback for environments without libc for Zydis.

This repository contains the official KiCad documentation.

Platypush is a general-purpose and extensible platform for automation across multiple services and devices with hundreds of supported integrations.

Enlightenment Foundation Libraries is a set of libraries developed for Enlightenment. Libraries covers data serialization, wide support for graphics rendering, UI layout and themes, interaction with OS, access to removable devices or support for multimedia.

Enlightenment is resource friendly desktop environment with integrated file manager, wide range of configuration options, plugin system allowing to unload unused functionality, with support for touchscreen and suitable for embedded systems.

Terminology is fast and feature rich terminal emulator. It is solely based on Enlightenment Foundation Libraries. It supports multiple tabs, UTF-8, URL and local path detection, themes, popup based content viewer for non-text contents and more.

Rage is a video and audio player written with Enlightenment Foundation Libraries with some extra bells and whistles.

Ephoto is an image viewer and editor written using the Enlightenment Foundation Libraries (EFL). It focuses on simplicity and ease of use, while taking advantage of the speed and small footprint the EFL provide.

Ephoto’s features include:

1. Browsing the file system and displaying images in an easy-to-use grid view.

2. Browsing images in a single image view format.

3. Viewing images in a slideshow.

4. Editing your image with features such as cropping, auto enhance, blurring, sharpening, brightness/contrast/gamma adjustments, hue/saturation/value adjustments, and color level adjustment.

5. Applying artistic filters to your image such as black and white and old photo.

6. Drag And Drop along with file operations to easily maintain your photo directories.

This is a process monitor and system monitor using the Enlightenment Foundation Libraries (EFL).

PYTHON-EFL are the python bindings for the whole Enlightenment Foundation Libraries stack (eo, evas, ecore, edje, emotion, ethumb and elementary).
