Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link Kerry Wong's posts on DIY optics, including a video on a scanning monochromator used as an optical spectrum analyzer. One commenter cites the video as the way to see a Verity unit in action.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
What Hacker News says?
I'm not familiar with how to do any sort of spectral analysis with a few discrete LED elements. Any pointers for further reading on that?
