- MIT’s “BioSuit” mechanical-counterpressure spacesuit project was discussed; the most recent public video appears to be from 2020 (YouTube link shared: https://youtu.be/03smqlKbGP0?t=4653).  
- Participants debated the practicality of a low-cost DIY HPLC system: preparative-scale HPLC can separate oligonucleotides and proteins, but high solvent use, maintenance, and parts costs make “cheap” HPLC unlikely.  
- A rotary-TLC “cyclograph” was proposed as a simpler, lower-maintenance alternative for small-molecule separations.  
- There was interest in building an inexpensive 1–2 T bench-top permanent-magnet NMR using neodymium magnets and precision PCB shim coils, though no detailed design exists yet.  
- Electrochemical additive manufacturing was revisited: a concept for a high-resolution electrode array using a photoconductive layer on a transparent conductor above a bright LCD/OLED panel was outlined, with concerns about pixel light leakage and reflections causing unintended deposition.
