- The Hackaday Raspberry-Pi Raman spectrometer remains un-validated for signal quality, while Ben Krasnow’s earlier DIY Raman rig is already calibrated and producing usable spectra, setting a practical benchmark for open-source spectroscopy.  
- Participants outlined a sub-$1 k open-source maskless photolithography path: LCD projectors at 2.5–5 µm/pixel with microscope objectives, sub-pixel mechanical stepping to erase inter-pixel gaps, and Kodak microfilm at 800 lp/mm as a globally available 1 µm mask substrate.  
- A 50 nm-resolution motorized XY stage (KY1250C-L) and 28BYJ-48 micro-stepped steppers were proposed for a modular open microscope; the design couples a 405 nm DMD lithography path, a Blu-ray pickup read path, and a video-camera checkerboard tracker for real-time backlash compensation.  
- Docker’s switch from LXC to libcontainer was flagged as a critical change for reproducible bioinformatics pipelines, while Transcriptic’s cloud lab reportedly uses Scheme-based tooling and is actively courting DIYbio experimenters.  
- The Center for Open Science strategic plan was circulated for critique: goals include universal research discoverability and incentive realignment toward correctness, but participants worry its top-down, Git-centric approach may exclude non-technical researchers.  
- Consumer DLP printers (e.g., B9Creator) advertise 25–50 µm resolution, yet no peer-reviewed micrographs confirm the claim; measured Z-axis repeatability of ~30 µm raises doubts about true feature fidelity.  
- Links and resources compiled: open-source laser-cutter Marlin firmware, Library Genesis mirrors for pay-walled literature, Tokyo University GHz liquid-metal RF microfluidics, and OpenLabTools microscope CAD files (currently incomplete and in need of parametric re-engineering).
