- A DIY-transhumanism meet-up presentation on the SKDB (Structured Knowledge Database) project successfully recruited 4–6 new members to the DIYbio, DIYh+, and Open-Manufacturing mailing lists and stimulated fresh IRC engagement.  
- The US Pirate Party informally pledged grassroots support to help restore a participant’s house and establish a bio/makerspace, while hackerspaces in Atlanta and Nashville demonstrated personalized RFID and USB-authentication door systems.  
- Participants debated the economics of equipping hackerspaces with high-cost gear, noting that a 23-member space paying $40/month would struggle to justify a $5 k unproven photolithography machine over proven tools.  
- SKDB development advanced with unit-conversion tests using sympy.physics.units, graph-search methods in graphsynth.py, and plans for web-spiders that could automatically order parts, alongside sharing of open-source hardware links such as Pearl Biotech’s gel box and a PCB-integrated electrochemiluminescence microfluidics paper.  
- Kanzure released 59 machine-readable RxOL recipe files from a 1985 “Computerized Cooking Recipes” book, prompting discussion on encoding food energy density (<6 kJ/g) and complexity metrics for automated recipe queries.  
- A “Guerrilla Guide to CNC Machining” by lcamtuf was highlighted as a practical open-source fabrication resource, alongside exploration of Python libraries (svgfig, PyX, pyfeyn) and a C NURBS library for custom CAD kernels.  
- Welding best practices were detailed: DC-negative for deeper steel penetration, DC-positive for thin metals, AC for aluminum oxide cleaning, and warnings against welding galvanized steel due to toxic zinc fumes.  
- Molecular sieves (zeolites) were proposed for low-cost noble-gas extraction from air, with eBay oxygen concentrators cited as ready-made sources, while genehacker sketched a speculative lab pipeline involving sodium electrolysis for chlorine and CO generation for phosgene synthesis.
