      Been meaning to ask you if you want a spectrometer module. I bought a bunch of reasonably good resolution ones on eBay (as part of a larger device). There’s a good thread on them here:https://laserpointerforums.com/threads/b-w-tech-spectrometer-473-module-setup-mods-info.101467/ …

      That thread is full of noise, but it sounds cute. How much are they?

          You can just have one I bought like 7, they were something like 20 to 50USD on eBay. Interestingly they were integrated into a pseudo-scientific Raman spectroscopy skin test device, contained lots of nice components however!
