# Key Points from #hplusroadmap IRC Discussion (March 16, 2015)

• Nick Johnson launched a Kickstarter for Tsunami, an Arduino-based signal generator capable of producing precise single cycles by running the microcontroller on the same clock as the Direct Digital Synthesis (DDS) system.

• Participants discussed microfluidics fabrication techniques, comparing DMD (Digital Micromirror Device) and LCD technologies for creating high-resolution photolithography masks, with calculations suggesting a modified 1080p projector could achieve approximately 1μm per pixel resolution.

• The technical specifications for microfluidic components were discussed, including reaction chambers (90μm width, 15μm depth) and microchannels (20μm wide, 150μm deep), with debates about the most cost-effective equipment options.

• Daeken expressed interest in contributing to DNA synthesis projects, with kanzure outlining immediate practical needs: purchasing a freezer for chemicals, ordering supplies, repairing a phosphoramidite tube in the synthesizer, and acquiring argon.

• The group shared information about Organic Syntheses (OrgSyn), a peer-reviewed chemistry resource where all procedures undergo verification for reproducibility in a Board of Editors member's laboratory.

• A discussion on CE certification testing revealed significant cost differences between regions ($500-$1000 in China versus three times that amount in the UK/US), with clarification that CE marking is "self-certified" but requires expensive test equipment.

• Participants explored cultural factors affecting organ donation in China, noting how traditional beliefs about bodily integrity after death contribute to organ shortages and speculating about the potential acceptance of artificial alternatives.
