Dave Richards's personal blog at aa7ee.wordpress.com covers hardware and science. Since 2019, 5 different Hacker News readers have linked it 6 times. It is still writing: the last post was on 2026-05-06, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN commenters cite this blog as a source on amateur radio and electronics builds, including a copper-clad prototyping board, a direct-conversion receiver and a joule thief kit.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
What Hacker News says?
Yes, I am sure. "Copper clad" - board with copper cladding on it. Here's a higher-quality picture taken at an angle from a different article where you can clearly see that it's not massive metal, but fibrous board: https://i0.wp.com/www.pbase.com/daverichards/image/136603883...

HN discussionSo true. One of the first things I did was build a direct conversion receiver with decent audio filtering. It had 45 mostly discrete components and sounded as good as a top end Yaesu. Similar to this one: https://aa7ee.wordpress.com/2012/07/27/using-the-nm0s-hi-per...

HN discussionI built a joule thief flashlight as part of a workshop at a security conference in 2018. We bought a kit that had all the parts, and then soldered them together. For a beginner soldering project, this is excellent. Unfortunately, I don't think the kit I built is still available. Here's some information I could dig up: - https://www.gigaparts.com/etow-humanalight.html - https://aa7ee.wordpress.com/2014/08/18/the-huma…
