- A 100 W laser was offered to genehacker for an unspecified project, and he enthusiastically accepted.  
- genehacker reported physical dimensions (0.25 in × 0.3 in) for a filter channel and mentioned that an “electronic gas balloon” concept he had previously discussed now appears feasible to build.  
- kanzure collected and shared a cluster of resources on mechatronics and dynamic-system modeling, including the Northwestern Mechatronics Lab wiki (with vendor lists, actuator inventories, and Kirchhoff-law primers), a Google-Spreadsheet lab inventory, and the 2009 CRC book “Mechatronic Modeling and Simulation Using Bond Graphs.”  
- He highlighted two seminal texts on system dynamics—Shearer, Murphy & Richardson (1967) and Rowell & Wormley (1997)—and linked to a 2008 ASME paper by Campbell on automated bond-graph modeling for computer-aided design.  
- kanzure experimented with OpenGL visualization code from NeHe lesson 19 (C-based) and searched for a Python port, finding the py3d.org link broken.  
- He noted the Ludum Dare game-jam event and pointed to two Pygame projects: “Dance Dance Revolution for DNA” and a cellular-automata-based game.  
- A link to the Neogentronyx hydraulic-machinery company was shared, with kanzure remarking on the mismatch between its quirky website and its heavy-machinery products.
