• genehacker posted an “ez-DNA synth proposal” to the diybio list that outlines a low-cost route to high-purity phosphoramidite nucleosides and an open-source microfluidic DNA synthesizer design; the group debated whether to scavenge reagents from existing campus machines or pursue a maskless-lithography version.  

• fenn sketched a speculative “DNA write-head” concept: an engineered polymerase complex that would synthesize arbitrary sequences when triggered by specific wavelengths of light, enabling massively parallel, cell-free DNA printing without conventional microarrays.  

• genehacker built and documented a wearable heat-exchanger shirt using a $5 motorized water-gun pump (0.17-inch impeller) from Toys R Us to circulate coolant through 15 ft of aquarium tubing, demonstrating ultra-low-cost thermal management for biohackers.  

• kanzure shared key resources: a thermodynamics paper on neural constraints (arXiv:0905.3690), a retrosynthetic route-designer paper, Tom Schneider’s ATP-driven “molecular rotation engine” patent, and a microfluidics literature archive at http://heybryan.org/books/papers/microfluidics/.  

• Participants discussed bypassing paywalls via a UT-Austin library proxy URL (http://ezproxy.lib.utexas.edu/login?url=guess-what) and noted the availability of Brackenridge Field Labs—two indoor labs plus 400-gallon algae ponds and new 20 × 20 × 3 ft outdoor ponds—for open-source biology projects.
