- A 100 km-wide space telescope was proposed as a way to achieve whole-Earth optical imaging fine enough for OCR of text on the surface.  
- Commercial 30× whole-human-genome sequencing is now available for ≈ $1,500 through Science Exchange core facilities, pushing personal genomics into “impulse-buy” territory.  
- Participants shared a $50–$80 open-hardware Raman spectrometer design built around the TCD1304AP CCD and discussed using InGaAs arrays for IR-range Raman shifts, enabling DIY ethanol detection and other chemical assays.  
- The SENS Research Foundation’s sample grant proposal for “GFP beer” (fluorescent yeast via electroporation) was circulated as a template for open-source longevity-research funding.  
- Open-source micro-stereolithography projects (lildlper, Lunavast XG2) and light-directed DNA oligonucleotide synthesis were explored, combining DLP micromirror arrays with UV LEDs to fabricate 10 µm-resolution microfluidics and high-density DNA microarrays.  
- DIY atomic-force microscopy guides (Hackaday, Instructables) were circulated, showing how to build an AFM with Lego, DVD tracks as calibration samples, and custom cantilevers.  
- A novel DNA-synthesis concept was sketched: photocleavable nucleotides that cleave into the correct base when illuminated by one of four specific wavelengths inside a nanometer-scale aperture, potentially driven by a protein ratchet.  
- Community projects showcased included a tree-mapping web app (https://github.com/heath/treemap-web) and open-hardware brewing tools like the Hackaday “Zymeter” for fermentation monitoring.
