- A 59 MB collection of 2009 microfluidics papers was shared at http://heybryan.org/books/papers/microfluidics/ and http://heybryan.org/books/papers/microfluidics_2009.zip, covering gravity-driven particle sorting, retrovirus bioreactors, ice-lithographic PDMS molding, wax-printer patterning, laser-printer micropatterning, and maskless UV-LED photolithography.

- Participants debated ultra-rapid prototyping recipes: microscope slides + UV LEDs + liquid photopolymer (isobornyl acrylate, TEGDMA, DMPA) for 5-min microfluidic chips, versus simply drawing channels with melted wax or a solid-ink printer.

- A plan emerged to build an open-source “fluidic stepper motor” compatible with RepRap—using 3-D-printable gears and the PneuStep pneumatic motor concept from Johns Hopkins—to create a steampunk robot controlled by digital fluidic circuits instead of electronics.

- Discussion of access control for the nascent Austin “fablab” (tentatively named myfab.org) weighed RFID cards against fingerprint or retina scanners, with a side project proposed to demonstrate how easily fingerprint readers can be spoofed.

- Rapid-prototyping ideas included using drinking straws and scissors as a quick linkage-design mock-up, and repurposing dot-matrix or inkjet printers to deposit water droplets that are flash-frozen into ice masks for micro-well molding.
