- timschmidt released stl2pov, an open-source converter that turns STL files into POV-Ray scripts for photorealistic 3-D print renders; code is on GitHub at https://github.com/timschmidt/stl2pov.  
- A $99 Harbor-Freight welder’s wire-feed potentiometer was proposed as a low-cost speed controller for DIY 3-D printers, though simply slowing the printer’s feed rate was judged the simpler fix.  
- kanzure added the DremelFuge open-source micro-centrifuge to SKDB and standardized the Eppendorf-compatible tube name as “eppie-microcentrifuge-tube” to maintain compatibility with Cathal Garvey’s conventions.  
- Channel members outlined a citizen-science plan to replace FDA food-safety assays by translating official chemical protocols into low-cost, open protocols executable in community labs like BioCurious and Genspace.  
- A DIY myostatin-inhibitor gene-doping project was scoped at $5–10 k, with discussion of FDA jurisdiction loopholes and links to Repoxygen (Oxford Biomedica’s erythropoietin gene therapy) and related DIYbio threads.  
- μManager (http://micro-manager.org) was introduced as open-source, cross-platform software for automated microscopy, supporting all major microscope brands and offering Python scripting hooks.  
- kanzure shared a personal archive of longevity papers at http://diyhpl.us/~bryan/papers/longevity/ and invited open-source mining for actionable anti-aging insights.  
- A Nature paper (461, 7266) on light-switchable protein interactions enabling spatiotemporal control of cell signaling was highlighted as a key optogenetics breakthrough; one co-author is known to the channel.
