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

Lepton EDA ia an electronic design automation (EDA) tool set forked from gEDA/gaf in late 2016. EDA tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Lepton EDA includes tools for schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout, and many other features.

FreeCAD is a general-purpose, feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE, and PLM. It is aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is modular, allowing for extension and customization.

This package contains binary data for Cura releases, like compiled translations. Prebuilt Firmware files are removed.

GNU LibreDWG is a C library to handle DWG files. It aims to be a free replacement for the OpenDWG libraries.

This package contains CPython bindings for libnest2d-for-cura.

QElectroTech, or QET in short, is a desktop application to create diagrams and schematics. The software is primarily intended to create electrical documentation but it can also be used to draw any kinds of diagrams, such as those made in pneumatics, hydraulics, process industries, electronics, and others.

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

Fastcap is a capacitance extraction program based on a multipole-accelerated algorithm.

SOLVESPACE is a parametric 3D CAD tool. Applications include:

• modeling 3D parts — draw with extrudes, revolves, helixes and Boolean (union / difference / intersection) operations

• modeling 2D parts — draw the part as a single section, and export DXF, PDF, SVG; use 3D assembly to verify fit

• 3D-printed parts — export the STL or other triangle mesh expected by most 3D printers

• preparing CAM data — export 2D vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining

• mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints

• plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing

GrblHAL CNC command sender, autoleveler, g-code editor, digitizer, CAM and swiss army knife for all your CNC needs. The sender is robust and fast able to work nicely with old or slow hardware.

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.
