KiCad is an open source PCB design and electronics CAD suite for Windows, macOS and Linux. It includes a schematic editor, a PCB editor and a 3D viewer, and is described as forever free. The schematic editor supports hierarchical designs and includes an integrated SPICE simulator and electrical rules checker. Documentation is written and maintained by a volunteer docs team.
An open-source software platform for distributed computing using volunteered resources. The BOINC app downloads scientific computing jobs and runs them in the background on a user's computer. About 30 science projects use it, investigating diseases, climate change, pulsars and other research.
An online index of the engravings and numbered paragraphs from Five Hundred and Seven Mechanical Movements. The index points to illustrations and descriptive text for mechanisms such as gears, escapements, steam engines and governors.
V2Rocket.com is a resource site about the German A-4/V-2 rocket, described as the world's first long-range ballistic missile deployed in combat. The site aims to give an accurate account of the rocket's design, production and combat deployment in World War II. It states that it does not promote any political ideology.
QPaths is a tool for building visual intuition for basic quantum terms. It offers superposition paths including Bell state, GHZ state, and QFT, and directs users to BlueQubit to simulate quantum circuits.
The TIB AV-Portal is a platform for scientific videos and audios in fields including technology/engineering, architecture, chemistry, information technology, mathematics and physics. It offers services such as quoting scientific videos with persistent identifiers, curating personal film programmes, publishing videos and producing videos with support. Content includes lecture series and digitised film collections.
Zygote Body is a free online 3D anatomy atlas for viewing and isolating human anatomy structures. It offers navigation, layer controls, selection and search, and different models. Paid Lite, Premium and Professional plans add tools such as saved scenes, annotations, slicing and quizzes.
