# Summary of #hplusroadmap IRC Log (April 13, 2010)

• A paper on patent pools was shared: "The Design of Patent Pools: The Determinants of Licensing Rules" from The RAND Journal of Economics, discussing licensing frameworks for technology sharing.

• Several hackerspace initiatives were discussed, including "hackerspaces in space" using high-altitude balloons, Thailand's first hackerspace, and the Austin hackerspace model of "a hackerspace within a hackerspace."

• Wolfgang Spraul's perspective on "copyleft hardware" was shared, distinguishing it from DIY hardware by emphasizing that it should be commercial, targeted to non-technical users, and create business opportunities rather than just hacking opportunities.

• A resource for hacking toy EEGs was shared (http://ericmika.com/itp/brain-hack), showing interest in brain-computer interface experimentation.

• A conceptual discussion about quantum dots injected into the brain appeared, describing how they could convert photonic signals to microwave frequencies for non-invasive brain monitoring using fractal planar antenna arrays.

• Various structural/modular building systems were compared, including MakerBeam, Contraptor, OpenStructures, MicroRAX, Bosch Rexroth beam, and others, with a survey being conducted to gather data for 80/20 Inc.

• Discussion of wearable computing technology noted the lack of commercially available systems, with suggestions that mobile phones are currently the closest thing to wearable computers.
