http://trafficwaves.org/
William J. Beaty, an electrical engineer from Seattle, explores the fascinating physics of traffic jams, treating highway congestion as fluid dynamics and demonstrating how a single driver can dissolve traffic waves. The site features animations, videos, experiments, and links to academic research on 'jam-absorption driving,' making it a surprisingly deep dive into an everyday phenomenon.
https://uvminerals.org/minerals/gallery
The Fluorescent Mineral Society hosts a stunning photo gallery showcasing minerals from around the world photographed under shortwave, midwave, and longwave ultraviolet light, revealing their glowing colors. Specimens from famous localities like the Franklin and Sterling Hill mines in New Jersey, Tsumeb in Namibia, and sites across China, Australia, and Brazil are featured with photographer credits and mineral identification.
http://wb6noa.com/
WB6NOA appears to be the personal amateur radio site of a licensed ham operator, identifiable by the callsign-based domain name. The site uses a frames-based layout typical of early web design, suggesting a hobbyist page dedicated to ham radio activities and interests.
https://autostakkert.com/
AutoStakkert! is free lucky imaging software created by Emil Kraaikamp for automatically analyzing, aligning, and stacking planetary and solar images captured through a telescope via high-speed video. The site offers downloads of multiple software versions (AS!2 through AS!4), sample images of Jupiter, Mars, and the Moon, and guides demonstrating how the stacking algorithm dramatically sharpens noisy astrophotography footage.
https://electronbunker.ca/eb/Links.html
A curated links page from the Electron Bunker site, gathering forums, personal pages, and resources dedicated to crystal radios, homebrew radio building, and vintage vacuum tube electronics. Regularly maintained and updated, it helpfully flags disappeared sites with Wayback Machine archives so enthusiasts can still access classic content.
https://julianbunn.org/
Julian Bunn is a computational scientist at Caltech with a background in particle physics at CERN, DESY, and the Rutherford Appleton Laboratory, now working on seismology and earthquake early warning systems like ShakeAlert. His sprawling homepage serves as a personal aide-memoire covering decades of scientific work, publications, ham radio, genetic algorithms, and even obscure retro computing projects from the DECUS era.
