- A $70 DIY spin-coater built from a recycled hard-disk-drive brushless DC motor was shared (http://nathan.instras.com/projects/spin-coater/index.html) and discussed as a route to uniform thin-film deposition for organic electronics such as diodes, transistors, sensors and displays.  
- Participants pointed to “maskless lithography with a DLP projector” and Google results showing how to convert a kitchen blender into a spin-coater and photoresist exposure tool, emphasizing ultra-low-cost micro-fabrication.  
- SU-8 epoxy photoresist was debated as a possible zero-outgassing, UV-curable protective “paint” for steel, with questions about maximum achievable thickness and porosity compared with two-part epoxies.  
- Links to open RIE (reactive-ion etch) reactor designs were collected, including a patented magnetic-field-enhanced plasma reactor PDF and a domestic-microwave-oven plasma reactor paper (AIP Rev. Sci. Instrum. 75, 5277 (2004)).  
- MEMS process reference material on SU-8 processing was circulated (http://memscyclopedia.org/su8.html) to support home micro-device fabrication.  
- A Slashdot story on “DIY Biologists To Open-Source Research” (http://science.slashdot.org/story/09/06/20/163200/DIY-Biologists-To-Open-Source-Research) was highlighted as mainstream validation of the channel’s open-science ethos.  
- Kanzure released and unit-tested new Python graph-analysis utilities (combinations.py, find-all-cycles.py) for extracting state equations from SKDB hardware packages, clarifying Kirchhoff’s voltage law and loop analysis for automated circuit modeling.  
- Technical troubleshooting covered static IP configuration on Linux (/etc/network/interfaces), shallow vs deep Python object copies (copy.copy vs copy.deepcopy), and package installation (python-pygraphviz, python-pydot) for graph visualization.  
- The group noted Elsevier and ScienceDirect outages on a Saturday morning, complicating paper access, while ybit offered to upload and rename newly acquired papers to the shared repository once SSH connectivity was restored.
