A low-cost Arduino based EFNMR Spectrometer

Seden · #1 01-01-2018, 04:46 PM

Ok Gentlemen, here is a true science based project for you guy's who know how to program Arduinos (screw PICS!). Here's a website that has the code for this project:https://wiki.brandoncurtis.com/w/DIY_NMR_Spectroscopy. Just do me the favor and post your results so I can build one for gold prospecting. I recently bought a used Deep UV-Xray Photodiode made by OSI optoelectronics that goes from 200nm to .07nm and was designed to be used for Xray spectroscopy. OSI gives you a single opamp circuit to use with the detector so that will be my project to get into XRF Analysis.

Enjoy

Seden thanks for the article.
There are so many articles at https://wiki.brandoncurtis.com/w/DIY_NMR_Spectroscopy that needs a lot of time to read them.
Especially when the English are not my mother tongue.

Geo,

Good to know and I understand now. I also have a great resource for Gamma Spectroscopy that from this youtube video comes close to Armin Bickels device with today's technology and ebay making everything so inexpensive to buy. I have a Gamma detector that uses a photomultiplier but found out that the Germanium based Gamma Detectors have a much sharper response. I found a design that was in Electronics Design Magazine (I believe) from an engineer from Maxim Semiconductors that uses a Germanium diode,alas another build project .

So many projects, so little time

I read the article but i don't understand what it is supposed to do. You put a banana in it and it gives you a voltage or time delay? It looks very much like a PPM. You said you might use it for prospecting. Do you put a soil sample in it and see if there is gold?

Ha ha, that is true Mike, beauce a PPM actually is an NMR in Earth's field, in which the sample is a Hydrogen rich fluid (like water, alcohol etc).

Hi all from Hellas.
I 'm newbee here so i will need your understanding.
In this thread i cant find the arduino code. Any luck?
TIA
