- A new YC-backed startup, Multiply Labs, offers custom time-release supplement pills via 3-D-printed capsules that can stagger the release of multiple ingredients.  
- ConstructVR is pitching in-house VR applications for enterprise training and visualization, while Aptonomy supplies autonomous quadcopter drones for real-estate and venue security patrols.  
- Discussion of construction-site safety hardware: participants favor small, wearable dosimeters and low-power dust sensors over bulky “barrier” boxes, and suggest adding LiDAR for real-time detection of moving hazards.  
- chris_99 shared a Raspberry Pi Noir camera spectrogram of spirits and asked for open-source offline software to calibrate and graph spectrometer images; nmz787_ pointed to his earlier Python project openSpectrometer.py on GitHub.  
- CaptHindsight highlighted a PLOS ONE paper showing ~20 % of genomics papers with Excel gene lists suffer from auto-conversion errors (e.g., “MARCH1” → “1-Mar”), underscoring reproducibility risks in bioinformatics workflows.  
- ApolloShield (anti-drone drone), Instrumentl (automated grant matching), Legalist (litigation-finance marketplace), Robby (self-driving mail robots), GTrack (nanoparticle tracers for oil reservoirs), and other YC Demo Day ventures were briefly surveyed.  
- A side thread explored building an open-source, web-based Evernote clone and Python-driven wiki to pool DIYbio and transhumanist knowledge more attractively than MediaWiki.
