The Pinouts Book is a free digital book for designers and engineers, serving as a quick reference for pinout functions in electronics projects. It covers 200 commonly used components, including connectors, single board computers, dev boards, memory cards and microcontroller chips. Pages link to official datasheets and specifications, and the latest version is reformatted for A4 printers.
MDCalc is a source for medical equations, algorithms, scores, and guidelines. It offers a library of calculators, including the Cockcroft-Gault creatinine clearance equation, a weight-based levothyroxine dose calculator, CKD-EPI GFR equations, mean arterial pressure, and the SpO₂/FiO₂ ratio. Tools can be browsed by specialty and filtered by calculation purpose.
Luna Multiplayer is a multiplayer mod for Kerbal Space Program. It provides servers, time synchronization over NTP, reliable UDP messaging, interpolation for vessels, NAT punchthrough, and shared career and science mode resources among players. Servers are listed within the mod, and server hosting is offered through a partner.
A blog by Matthen presenting maths and science animations, including simulations and visualizations such as waves, rolling ellipses, Borromean rings and conic sections. Some posts link to code and interactive visualizations.
Phoenix RC is an educational resource for documentaries, courses, books, reference material, or self-learning.
Half Cat Rocketry is an X account with 730 posts describing itself as lowering the barrier to entry into amateur liquid rocket engines. The account links to HalfCatRocketry.com and was joined in July 2021.
An artificial life simulation tool built on a specialized 2D particle engine in CUDA for soft bodies and fluid-like media. Simulated bodies are networks of particles that can be given higher-level functions, such as sensors, muscles and neural networks, and act as digital organisms in a common environment. The software is open-source under the BSD-3-Clause license.
