# Summary of #hplusroadmap IRC Discussion (Nov 19, 2009)

• Discussion about the feasibility of creating an open-source hardware semiconductor fabrication facility, with participants noting that traditional fabs cost billions but vacuum technology might be a limiting factor for low-cost alternatives.

• Lee Smolin's work on complexity science and theories of the universe was shared, including his chapter "A Theory of the Whole Universe" (http://www.edge.org/documents/ThirdCulture/z-Ch.17.html).

• Users discussed challenges with installing PythonOCC, an open-source 3D CAD/CAE Python library, with specific focus on environment path configuration issues.

• Several LEGO-based automation projects were shared, including a knitting machine (http://www.youtube.com/watch?v=MV19wqtfyF0), an automated warehouse system, and a car assembly machine, with discussion about incorporating these designs into SKDB.

• The group discussed file format standards for 3D models in their SKDB project, with a preference for IGES or STEP formats over STL for storing LEGO component designs.

• A sharpie-based microfluidics application was mentioned, showing interest in low-cost DIY approaches to typically expensive laboratory technologies.

• Participants noted a missed opportunity to see Jack Szostak (likely Nobel laureate in Physiology or Medicine) who had visited campus that day.
