# Summary of #hplusroadmap IRC Log (November 8, 2015)

• A reagent price tracking and comparative shopping tool was shared (p212121.com), which could be useful for researchers looking to optimize costs for laboratory supplies.

• A significant microfluidics advancement was mentioned: a system capable of producing over 30 billion 45μm diameter droplets per hour, as documented in a paper from the Royal Society of Chemistry.

• A user shared information about Pteromys, an interactive design and optimization tool for free-formed free-flight model airplanes that uses machine learning techniques instead of expensive fluid dynamics simulation.

• A brain research project was discussed involving 70nm slices of approximately 150 donated brains from individuals who had IQ tests in the 1930s-40s, potentially providing insights into brain aging and cognitive function.

• A BCI (Brain-Computer Interface) project using OpenBCI and P300 signals was shared, though there was skepticism about the practical limitations of EEG-based interfaces and their low information transfer rates.

• A discussion about Grasshopper 3D (a parametric modeling plugin related to OpenNURBS and Rhino) took place, with mention that BRLCAD's implementation of OpenNURBS might be more useful for certain applications.
