- Open-source microfluidics controller “OpenFluxl” shared on GitHub (https://github.com/waagsociety/OpenFluxl); participants puzzled over its serrated-pixel design and teal appendages, speculating about valves and tubing.  
- BioHackAcademy repositories (https://github.com/BioHackAcademy) noted as a new source of open bio-hardware designs, including SketchUp files.  
- Discussion of low-cost cyanobacteria-derived sucrose production at ~5 ¢/lb—compared with current wholesale refined-sugar prices of 30–60 ¢/lb (US) and 15–30 ¢/lb (world)—as a potential disruptor of the corn belt.  
- Reference to “solid-state bioreactor” image (Proterro) illustrating an enclosed photobioreactor concept for high-density sugar secretion.  
- Amateur astrophotographer accidentally captured a sharper image of a SpaceX CRS-6 first-stage landing than the official press photo; image circulated via Reddit (http://i.imgur.com/SppRXAQ.jpg).  
- Falcon Heavy flight-animation video (https://www.youtube.com/watch?v=4Ca6x4QbpoM) and CRS-6 landing footage (https://youtu.be/BhMSzC1crr0) shared as visual references for reusable-rocket progress.  
- nmz787_i building an RS-232 sniffer to reverse-engineer the protocol of an inexpensive “blue” spectrometer; initially intended to emulate a serial mouse.  
- chris_99 inquired about DIY near-field scanning optical microscopy (NSOM); nmz787_i provided academic contacts and a targeted PDF search string: “sanchez raman crystal filetype:pdf 32768 kHz”.  
- Graffiti Research Lab’s L.A.S.E.R. Tag system (https://www.youtube.com/watch?v=DKbtTPYZEig) mentioned as an example of large-scale, light-based public interaction.
