foxBMS is a free, open and flexible development environment to design battery management systems. It is the first modular open source BMS development platform.

FreeCAD is an open-source engineering design suite designed for parametric 3D modeling, architectural planning, and mechanical assembly. It functions as a professional-grade platform that utilizes history-based operations to allow for non-destructive design updates, enabling users to construct complex geometry through a sequence of constrained sketches and solid operations. The platform distinguishes itself through a highly modular, workbench-based architecture that allows users to tailor the interface and toolsets to specific engineering domains. It features deep Python integration, which se

Here you'll find a growing collection of 3D models, textures, and images from inside NASA.

A model generator for energy system modelling and optimisation (LP/MILP).

An extension for Inkscape that makes it easier to draw optical diagrams.

OpenSCAD is a script-based 3D modeler and parametric CAD tool that generates three-dimensional solid objects from programmable scripts. It utilizes a constructive solid geometry engine to create complex shapes by performing boolean operations on basic geometric primitives. The system functions as a compiler that transforms a functional language into geometric representations, allowing for precise dimensional control through variables and functions. It features a WebAssembly implementation that enables the geometry pipeline to execute directly within web browsers. The software covers a broad

Embedded-hal is a hardware abstraction layer for embedded microcontrollers that defines common traits allowing peripheral drivers to remain entirely independent of specific hardware platforms. The library provides platform-agnostic interfaces that decouple driver logic from microcontroller architectures, utilizing zero-cost trait abstractions that compile down to direct hardware register manipulations without runtime overhead or memory allocation. The project features asynchronous execution support and synchronous-to-asynchronous adaptation, enabling non-blocking peripheral operations and coo

Chisel is a hardware construction language and description tool used to define digital circuits. It functions as a generator that converts high-level hardware descriptions into synthesizable Verilog code for use in ASIC and FPGA design. The project enables the creation of parameterizable hardware templates and reusable digital components. It leverages functional and object-oriented programming patterns to transform complex circuit representations into finalized hardware descriptions. The toolset covers the register-transfer level design workflow, allowing users to model digital circuits usin
