• A new open-source web-based circuit editor, circuits.io, was announced; participants noted it should integrate with SPICE for simulation.  
• Discussion of Cathal Garvey’s “indiebiotech.com” business model: he labels his work “open source” yet requests that others not commercialize it, prompting criticism on the diybio mailing list.  
• OpenWorm project (openworm.org, github.com/openworm) was highlighted as the current community effort to simulate the complete C. elegans nervous system; contrasted with the earlier MURG (Microtome Upload & Reconstruction Group) nematode-upload project whose hardware reportedly ended up in an unknown lab.  
• Practical DIY thread on selecting an inexpensive refractometer (e.g., RHS-10ATC salinity model on eBay) for urinalysis (desired range 1.000–1.040); participants weighed buying versus building, concluding off-the-shelf is cheaper.  
• A side project idea emerged: using the GitHub API to compute tongue-in-cheek “ERA” (earned run average) metrics for programmers and publish a leaderboard, similar in spirit to Coderwall.  
• Security links shared: a lone malformed packet crippled telco networks in Eastern Europe, with accompanying HITB conference slides “6000 Ways and More” detailing telecom signaling attacks.
