- George Whitesides’ paper-microfluidic “lab-on-paper” diagnostics were highlighted, with open-access design files, ACS papers, and the FLASH rapid-prototyping method collected at designfiles.org/papers/whitesides/ to accelerate low-cost point-of-care testing.  
- A proposed $10 M X-Prize for brain–computer interfaces sparked debate on whether large cash prizes meaningfully accelerate BCI progress and on the need for open, standardized interconnect specs to prevent proprietary fragmentation.  
- A multi-year actogram dataset (fennetic.net/sleep) was shared as a model for self-quantification, demonstrating minute-level tracking of sleep, coding, and other activities; participants stressed that effective data visualization is essential for communicating health-tracking insights.  
- The open-source SKDB (Structured Knowledge Database) framework is being used to design and document a low-cost DIY book scanner, serving as a canonical hardware-packaging example while highlighting the need to create new SKDB modules for scanners and paper feeders.  
- Laboratory mice (~$100 for four) were offered for neuroscience experiments, and curated folders of “biological cybernetics” papers were pointed to for replicating 2008 neural-network simulations with PyBrainSim.  
- OpenCV vision processing on the BeagleBoard DSP was discussed; only fragmentary HB-robotics wiki notes exist, underscoring the gap in open-source embedded vision tools.  
- Links to open-source space efforts (cstart.org, GPL code) were contrasted with earlier OpenVirgle work, emphasizing the importance of better project archaeology for long-term open-source continuity.
