I'm Dave located near the San Francisco bay area. I'm fairly new to electronics and am diving a little deeper into the mystery of it all. I work in the manufacturing field - more specifically, dimensional metrology. My goal here is to gain a better understanding of how circuits work and why they work. The end goal is to be able to build a working raman spectrometer. Cheers!

@dyeagly - Welcome from a relatively new and ignorant novice. Gotta say your intro definitely had me Googling raman spectrometer, fascinating!

Great to have you on board. I had to google "Raman Spectroscopy" too.
I studied chemistry and metallurgy over 40 years ago and we used photometry, flame photometry, spectroscopy, gas chromatography and x-ray fluorescence for analysis. We were more interested in elements rather than molecules. I suppose that the techniques that you use are a follow on from x-ray crystallography as used by Rosalind Franklin to discover the DNA double-helix.
Where we differ from the rest of the forum is that we know the electrical charge is negative, and flows from negative to positive, because if anything is moving in an electrical circuit it is electrons.
Bear this in mind if you get into hot debates! ? ? ?

Welcome, Dave!
And like all the other respondents I also had to search for "raman spectrometer". And, sure enough, there are a number of YouTube videos on building one!
Hackaday.io also featured one using a (very old) Raspberry Pi about 6 years ago.
Not sure I'll be building one soon as I have no idea what I would use it for. But I would probably be the only kid on the block who has one, so that's an incentive!

Wow to be the first kid on the block to have the first of everything! My goal in life! ?

My wife once had a plaque with that quote on it hanging in my shack. Or what is now commonly referred to as a man cave.
