- A Hackaday project for reverse-engineering LVDS laptop display pinouts was shared, with a wish for faster, semi-automatic pinout discovery tools.  
- Discussion of building an open-source automated x-y-z microscope stage referenced the Cambridge OpenLabTools microscope project and plans to motorize existing scopes for chip decapping and imaging.  
- A tutorial on etching 200 nm tungsten micro-probes for chip probing was circulated (siliconpr0n.org), along with a vendor quote of $200 each for a 5-piece minimum.  
- Techniques for decapping ICs using warm/fuming nitric acid were mentioned, plus interest in Focused Ion Beam (FIB) sample prep.  
- Breath-alcohol monitoring during fermentation was debated: CO₂ sensors could infer alcohol, but direct ethanol measurement requires strict control of headspace volume and temperature to keep fuel-cell breathalyzers in range.  
- A link to NASA’s open library of space sounds for creative use was posted.  
- A Hacker News claim that fungi now decompose dead trees so efficiently that no new coal, oil, or gas will form sparked tongue-in-cheek calls to “kill all the fungi.”  
- The Pugh decision-matrix method for engineering trade-offs was introduced as a structured way to score competing design options.  
- A $23 JYE Tech pocket oscilloscope was considered for hobby electronics, illustrating how cheap, capable test gear is becoming widely available.
