- A two-channel acrylic microfluidic mixer for dye experiments was proposed as a quick project, alongside links to commercial near-field wireless power systems (WiTricity and eCoupled).  
- Injection molding was debated: Ian_Daniher saw it as hard to DIY, but fenn pointed to Dave Gingery’s $3 k desktop machine and a free PDF on heybryan.org showing how to build one.  
- Robert Lang’s “TreeMaker” origami software came up; kanzure suggested it could be automated to generate folding instructions for arbitrary shapes, not just crease patterns.  
- fenn reported from a SETI talk on PALM/vPALM microscopy: single-molecule localization with ~15 nm resolution by sparse photo-activation and deconvolution, yielding 3-D point clouds of chromophore positions.  
- Hackerspace economics were discussed: AS220 (Providence) charges $50/month + $16/h, Boston’s new space is considering similar fees, and participants worried that training/tool surcharges discourage learning.  
- kanzure shared the Brighton DIYbio node thread and the Neurohackers Association site, while Trooem asked about stem-cell cancer risk and the availability of consumer neuro-imaging gear.  
- A droplet-microfluidics video (encapsulation of three liquids, Janus particles) was linked as a possible route to DIY e-ink or molecular-gastronomy “caviar.”  
- kanzure successfully moved the HeeksCAD project to its own domain (http://heekscad.org) after fixing an Apache2 sites-available vs. sites-enabled oversight.
