I enjoyed reading it. Expression and culture through hardware modification and engineering.

Found this website.

Summits on the air not mentioned in the article.

It’s great amateur radio. Which I’ve learned is not about reliable communication. It is the sport of “can you here me now?”. Lots of tinkering and testing. The fun of Seeing the network open up when someone attaches a node to an airplane. Or occasional conversations that pop up. Set expectations low and get into appreciating direct EM wave communication.

If I might also plug ‘the Atlas of Fourier Transforms’. If your interested in understanding building intuition of symmetry and phase in fourier space, the book illustrates many structures.

Some context for HN: This is a self-published book, which is nonstandard in my field. Usually you work with large academic publishing groups. The choice of self-publishing is an unknown process to most academics in science and engineering. It afforded me an opportunity to learn more about publishing, bookmaking, marketing, and distribution. Self-publishing allows the author to retain creative control on how the book is made, presented, and shared.

I know HN is interested in academic publishing policies, copyright, DRM, etc. This project presents an alternative for researchers to share knowledge.

The “Atlas of Fourier Transforms” caters to enthusiasts of all proficiency levels. Here, the reader embarks into the world of Fourier transforms through carefully curated images of Fourier pairs. As the atlas unfurls, it includes concepts of symmetry, rotation, translation, addition, multiplication, and interference. For those well-versed in the art of Fourier analysis, ”The Atlas of Fourier Transforms” offers an unparalleled dictionary of structures and their corresponding Fourier counterparts.

The article does not explain how they entered it into the public domain. One cannot just declare something is public domain. Public domain is a special circumstance.

Blatant fraud is rare in physics, engineering, chemistry. Lying is rare. Quality is high at the highest institutions of physics and chemistry. Exaggerated claims occur, but much less than in day to day life. Top visibility work is quickly reproduced. Reproduction is the essence of science.
