- SKDB development: fenn and kanzure are actively extending the SKDB codebase, adding graph-based representations of part connections, fixing OpenCASCADE (pythonOCC) coordinate-system bugs (gp_Ax2 vs gp_Ax3 handedness), and committing new utilities like Interface.get_transformation(), make_arrow_to(), and show_interfaces().

- Arduino ecosystem: timschmidt announced he is manufacturing and selling GPLv3-licensed Arduino clones with on-board relays, power MOSFETs, and environmental sensors; kanzure urged packaging the kits into SKDB to automate distribution and documentation.

- DIY fabrication knowledge: katsmeow shared detailed practical advice on home welding—recommending 7018 rods, DC current, ≥30 A @ 240 V supplies, and warning against underrated microwave-oven-transformer welders—while ybit received an Instructables PDF on converting microwave transformers into stick arc welders.

- Open-source biology: any56289043 posted a news snippet on plant-made nanoparticle vaccines (tobacco-mosaic-virus vectors expressing norovirus proteins), and kanzure celebrated diybio.org’s new “projects” page that now lists community initiatives.

- Transhumanist culture: discussion touched on “cellular memory” anecdotes from heart-transplant recipients, the ESP/Tent collaboration (#esp, #openkollab), and the relocation of the Austin “fabratory” to California; ncravens sought feedback on a Google-Doc proposal, while genehacker returned from dive certification in Cozumel.
