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

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.

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

r2ghidra is a radare2 plugin which integrates the Ghidra decompiler.

Manifold is a geometry library dedicated to creating and operating on manifold triangle meshes. A manifold mesh is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc.. Manifold also supports arbitrary vertex properties and enables mapping of materials for rendering use-cases.

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.

ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile C code for the API of spice simulators. Based on transformations specified in XML language, ADMS transforms Verilog-AMS code into other target languages.

Area is a CAM-related software for pocketing operation.

This project provides library and associated python-module to compute pocket operations.

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.

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

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.

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

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

scad-dbus allows controlling OpenSCAD from within Emacs via D-Bus without having to switch programs or reach for the mouse.

pcb2gcode is a command-line program for isolation routing and drilling of PCBs. It takes Gerber files as input and outputs G-code files for the milling of PCBs. It also includes an autoleveller for the automatic dynamic calibration of the milling depth.

Binary G-code is a new standard for encoding and compressing ASCII G-code files. G-code files are easy to read and interpret, but their downside is that the data is not saved efficiently, and the file size is often very large. Compression of the file is problematic because the printers usually run on limited hardware and they may not have enough memory and/or CPU power to decompress it.

Block and Binary G-Code is a new G-code file format featuring the following improvements over the legacy G-code:

• Block structure with distinct blocks for metadata vs. G-code.

• Faster navigation.

• Coding and compression for smaller file size.

• Checksum for data validity.

• Extensibility through new (custom) blocks. For example, a file signature block may be welcome by corporate customers.

The binary G-code format is flexible and the encoding and compression of individual blocks is variable. libbgcode library contains the routines to convert ASCII G-codes to binary and vice versa.

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

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.

Arduino Command Line Interface is an all-in-one solution that provides Boards/Library Managers, sketch builder, board detection, uploader, and many other tools needed to use any Arduino compatible board and platform from command line or machine interfaces.

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.

Capstone is a lightweight multi-platform, multi-architecture disassembly framework. Capstone can disassemble machine code for many supported architectures such as x86, x86_64, arm, arm64, mips, ppc, sparc, sysz and xcore. It provides bindings for Python, Java, OCaml and more.

Iaito is the official graphical interface for radare2, a libre reverse engineering framework. Iaito focuses on simplicity, parity with commands, features, and keybindings.

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.

The Fritzing application is Electronic Design Automation (EDA) software with a low entry barrier, suited for the needs of makers and hobbyists. It offers a unique real-life "breadboard" view, and a parts library with many commonly used high-level components. Fritzing makes it very easy to communicate about circuits, as well as to turn them into PCB layouts ready for production.
