- A 40 W CO₂ laser cutter (FSLaser) was demonstrated for rapid PCB prototyping by ablating black paint to ash; 25 W is sufficient for this purpose.  
- Participants debated Gibson assembly overlap requirements, questioning whether 20–40 bp is truly necessary when ligating ~2 million DNA strands.  
- Valve-based microfluidic multiplexing was proposed as a lower-waste alternative to continuous-flow systems in DNA synthesis workflows.  
- Gen9Bio’s inkjet printing of phosphoramidite reagents was highlighted as achieving $0.00001–0.001 per nucleotide—2–4 orders of magnitude cheaper than column-based oligos—enabling 10,000-oligo pools.  
- Microarray-derived oligos were identified as a disruptive cost-reduction method for large-scale gene assembly projects.  
- Paperbot successfully retrieved pay-walled articles (Nature 346:818, Springer 10.1007/BF01580223, Taylor & Francis 10.1080/07328319108046457) via LibGen and local mirrors, illustrating an active open-access workaround pipeline.  
- A Node.js RTL-SDR library (node-rtlsdr) was shared for software-defined-radio experimentation.  
- Python packaging challenges were discussed, particularly detecting C-extension build capability (Python.h, compiler toolchain) within setup.py for conditional install_requires.
