THE PULSAR Engineering is the company blog at thepulsar.be, writing about science and hardware. Since 2020, 4 different Hacker News readers have linked it 5 times. No feed was found, so read it on the site itself.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link THE PULSAR blog for its DIY Raman spectroscopy work, including the OpenRAMAN open-source spectrometer and a breadboard Raman build. One commenter praises the spectra results shown in its posts.
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?
So the kit costs €2300 for all the parts. Looking through the BOM, I feel there's a good bit of fat to be trimmed actually. They splash €85 on a linear regulated power supply (you can get something similar giving clean power for $20 in bulk), and the camera setup (sensor, lens, related hardware) costs more than €600 in total. While there's a good reason they picked the lens they did [0] I feel the sensor (might) be…

HN discussionThe original RamanPI project looked interesting but doesn't seem to have gone anywhere after several years, unless I'm mistaken. If there's any actual data from it, I couldn't find it. On the other hand, Luc's results are drop-dead awesome: http://www.thepulsar.be/article/some-diy-raman-spectra/

HN discussionRaman is inherently difficult as it's so weak compared to normal scattering, so careful optimization of SNR is required. Another DIY Raman setup (on a breadboard so expect few kg): https://www.thepulsar.be/article/openraman-starter-edition/
