# Key Points from IRC Log - August 19, 2009

- A DIY welding guide using microwave transformer was shared, followed by expert advice on welding techniques, including recommendations to use 7018 rod exclusively rather than 6013/6011 rod, and DC power for better results.

- Discussion of Arduino clone development with additional features (relays, power MOSFETs, temperature sensors) for commercial production, with designs to be released as open source hardware.

- Ongoing development of SKDB (Standard Kit of Building Blocks) software, with developers working on geometric transformations, interface connections, and part assembly representation using graph structures to model connections between components.

- Updates on the "Austin Fabratory" maker space, with mentions of possible relocation to California, showing the early development of community fabrication spaces.

- A project page for DIYbio.org was successfully launched, representing progress in organizing open-source biology projects and resources.

- Discussion of a job opportunity at a manufacturing company with machining equipment (lathes, welders) and capabilities for circuit board design, highlighting growing interest in small-scale manufacturing.

- Brief discussion of cellular memory in heart transplant recipients, referencing anecdotal reports of transplant recipients experiencing memories from donors.
