Interesting other forum threads on low-cost raman

I received my R spectrometer from Thunder Optics, and when I opened it up I found a nice B&W tek BTC-110S** .
This led me to some google searches where I found an old post from Luc on another forum:
The same forum has some other good threads worth mentioning
The last one has images of a design made out of legos that I found hilarious! Have amatures are gone too far??
There is still B&W tek units for sale, but I think I'm going to get a used ASEQ. I am thinking that the spectrometer part of Luc's design might be worth separating out into its own fiber-driven unit that could be used for a variety of uses. These B&W ones are running out and I don't think there is an open design one as easy to align. There is this one but someone in this community reached out and the maker of it says they ran into some problems with being able to align it.
** Okay what actually happened is I plugged in the wrong power adapter, a 12V instead of 5V for just a second, and now it no longer works. This led me to open it up and saw a scratched off label from the czerny-turner unit which was suspicious. A little while later I was looking on Ebay for cheap spectrometers and wow! Something that looks just like the inside for half the price. That's how I figured out what it really is. So I'm guessing thunder optics just buys these, fixes them up and sells them in a nice aluminum case.
