- A user shared the open-source ArduCopter project, an Arduino-based autopilot system for multi-rotor aircraft hosted at http://code.google.com/p/arducopter/.  
- Discussion of the Design Structure Matrix (DSM) surfaced when a participant linked its Wikipedia page, noting it was new to them and likely relevant for system-design work in open-source hardware projects.  
- A request for help retrieving the pay-walled paper “Absence of Confinement Resonances in Low-Energy Electron Collisions with C₆₀” (Phys. Rev. Lett. 101, 133001) led to a successful community share via a temporary PDF mirror at http://jonathanstreet.com/static/2008Muller.pdf.  
- The group briefly referenced the documentary “Anima Mundi” (available at http://video.google.com/videoplay?docid=2391673215252131298#) as a resource on evolutionary and transhumanist themes.  
- Half-serious calls were made for community fabrication of custom scientific instruments—specifically a monochromator and a synchrotron—underscoring ongoing interest in low-cost, open lab hardware.
