* Feburary 2023: Failed Switchmode PSU in the shim control box was replaced with a center-tap transformer and a self-designed +/-15V 7815/7915 linear PSU on an aluminum substrate PCB.

* As of March 2023, it still works.

* October 2023: Primary Hard Drive (32GB SSD failed.) Recovered onto some random hard drive with <code>dddrescue</code>. Instrument online again. Pending analysis of corrupted files via <code>ddru_ntfsfindbad</code>

* Yep, there's no 'D' on the periodic table. When you see a 'D' in a chemical formula, it is [https://en.wikipedia.org/wiki/Deuterium Hydrogen-2. When this form of hydrogen is used in a compound, it is often referred to as being "Deuterated". This is a form in which the hydrogen atoms are replaced with a more rare (but stable) isotope of hydrogen. The reason for doing this is that this form of hydrogen is not "NMR Active". Normally, a strong hydrogen signal (from say, plain water) would overwhelm the incoming NMR signal, thus making it harder to see small peaks. Deuterated solvents are used because they are not NMR active and so would not contribute to the spectrum.
