# Key Points from IRC Discussion

• Kanzure is developing a Python-based CAD visualization tool using OpenGL as an alternative to OpenSCAD, designed to provide real-time visualization while typing commands like "sphere.fuse(box)" without the limitations of OpenCascade.

• Participants discussed self-replicating machines, with criticism that RepRap's claims of self-replication are exaggerated since it cannot manufacture its own electronic components, highlighting the gap between current 3D printing technology and true self-replicating systems.

• A Harvard research paper on "Social Prosthetic Systems" was shared, exploring how technology can augment human cognitive and social capabilities: http://www.wjh.harvard.edu/~kwn/Kosslyn_pdfs/2006Kosslyn_chap_in_EvCogNeuro_SocialProstheticSystems.pdf

• The group debated open hardware manufacturing strategies, suggesting that creating free ASICs should precede attempts at free FPGAs, starting with simple 5-10k gate designs at 500nm process, while acknowledging the significant barriers to open-source CPU fabrication.

• Wolfspraul shared information about Qi Hardware and Sharism's Ben NanoNote (which has sold about 900 units), demonstrating practical attempts at creating open hardware devices while navigating the tension between using some proprietary components versus pursuing a purist approach.

• NASA Ames researchers discovered that many consumer electronics, particularly small phones, function normally in vacuum conditions, which has promising implications for amateur satellite applications.
