- The channel debated the “AB tube,” a proposed ultra-high-vacuum, positively-charged cylinder meant to electrostatically confine electrons; skepticism focused on electron-wall recombination and real-world instabilities, with arXiv:0704.3466 cited as the theoretical basis and warnings issued against novice high-voltage work.  
- Fabrication talk covered electrochemical machining of tungsten-carbide PCB micro-drill bits, their scarcity, and their symbolic role in post-industrial fab-labs.  
- Gene’s partial RepRap build in Austin—plastic parts printed but lacking steppers, electronics, and a working printer—was inspected during an impromptu meet-up at a local café.  
- Kanzure released two curated resources: a 15 k-link, 3.2 MB personal bookmark archive (http://heybryan.org/bookmarks/gene’s_bookmarks.html) and an index of “interesting” Open Manufacturing mailing-list threads (http://heybryan.org/om.html) to help newcomers navigate the community.  
- A request was made for a machine-readable, synonym-rich gene list for any organism; NCBI was considered scrape-heavy, while the 14 GB KEGG genes.tar.gz was identified as a promising but unwieldy source needing custom parsing.  
- Fringe links from roboeco.com/evolutis and teaminfinity.com—including “UniversalDNA.txt” and 1996-era chat logs—were shared and met with bemused dismissal rather than serious technical engagement.
