CuraEngine is an engine for processing 3D models into 3D printing instructions for Ultimaker and other GCode-based 3D printers. It is part of a larger project called Cura.

GNU PCB is an interactive tool for editing printed circuit board layouts. It features a rats-nest implementation, schematic/netlist import, and design rule checking. It also includes an autorouter and a trace optimizer; and it can produce photorealistic and design review images.

This package provides a full Python driver for the Keithley 2600B series of source measurement units. This driver provides access to base commands and higher level functions such as IV measurements, transfer and output curves, etc. Base commands replicate the functionality and syntax from the Keithley's internal TSP Lua functions.

The audio measurement system is a system for audio measurement through sound card. It contains: generator, oscilloscope, audio spectrum analyzer (FFT) and frequency sweep plot.

Microcom is a minimalistic terminal program for accessing devices via a serial connection. It features connection via RS232 serial interfaces (including setting of transfer rates) as well as in telnetmode as specified in rfc2217 and a (Linux specific) CAN mode.

GPX is a post processing utility for converting gcode output from 3D slicing software to x3g files for standalone 3D printing on common 3D printers.

LibCharon is a Python file metadata and streaming library. It belongs to the Cura project from Ultimaker.

This package provides a computer algebra system geared towards field theory.

Fasthenry is an inductance extraction program based on a multipole-accelerated algorithm.

This package provides a pipeflow calculation tool that complements pandapower in the simulation of multi energy grids.

OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple API

scad-mode provides an Emacs major mode for editing OpenSCAD code. Features:

• Syntax highlighting

• Basic completion function (press M-TAB)

• Preview rendered model in separate window (press C-c C-c)

• Open buffer in OpenSCAD (press C-c C-o)

• Export buffer with OpenSCAD (press C-c C-e)

• Flymake support (enable flymake-mode in scad-mode buffers)

• Org Babel support (scad source blocks)

Valeronoi (Valetudo + Voronoi) is a companion for Valetudo for generating WiFi signal strength maps. It visualizes them using a Voronoi diagram.

Python bindings for orocos-kinematics-dynamics.

Lcapy is a Python package for linear circuit analysis. It uses SymPy for symbolic mathematics.

Lcapy can symbolically analyse circuits described with netlists or by series/parallel combinations of components. It can also manipulate ontinuous-time and discret-time expressions.

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.

Udis86 is a disassembler for the x86 and x86-64 class of instruction set architectures. It consists of a C library called libudis86 which provides a clean and simple interface to decode and inspect a stream of raw binary data as disassembled instructions in a structured manner, and a command line tool called udcli that incorporates the library.

OpenEMS is an electromagnetic field solver using the FDTD method.

GUI library for csxcad --- a library for describing geometrical objects and their properties. This library is used in appcsxcad which provides a standalone graphical frontend to {csxcad

GNU poke is an interactive, extensible editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.

This package provides a C++ library for handling of multiple co-processes in cadabra.

ASCO brings circuit optimization capabilities to existing SPICE simulators using a high-performance parallel differential evolution (DE) optimization algorithm.

libmodbus is a library to send/receive data with a device which respects the Modbus protocol. This library can use a serial port or an Ethernet connection.
