• TU-Delft’s 2013 iGEM team published a complete open-source build for “Zephyr,” a $1,500 fluorescence scanner that replicates the $120 k Typhoon instrument by using low-cost optics and omitting seldom-used confocal features; full instructions are on the iGEM wiki.

• A lightweight Python data-modeling library named “modelo” was released at https://github.com/kanzure/modelo; it decouples model definitions and type validation from SQL/ORM dependencies so the same schemas can be reused across projects without forcing SQLAlchemy everywhere.

• Channel members debated the best way to share scientific knowledge: one side favors curated, single-paper discussion threads over blog posts or sprawling PDF directories, while others insist that large paper archives remain essential for discovery.

• DIY-bio lab logistics were dissected, covering $4 k Panasonic –80 °C freezers, renters-insurance coverage for off-site equipment, and micro-layout optimization for small rooms (microscope placement, bench sizes, label-makers).

• Historical technical links were shared on the first medical ultrasound experiments, including Karl Dussik’s 1942 water-bath brain-tumor imager and Japan’s 1950s–60s water-bag B-scanners, complete with photos and engineering details.

• A Google Drawing circulated for a wearable exoskeleton concept that augments upper-body strength specifically to resist pulling forces on held objects, inviting mechanical-design feedback.

• Ongoing open-hardware projects mentioned: a completed BOM for an open-source spectrometer and stalled plans for a home-built DNA/RNA synthesizer, plus an unresolved side quest dubbed “operation make antibodies yo.”
