# Key Points from #hplusroadmap IRC Discussions

• Participants discussed using LEDs as photodiodes for light sensing applications, noting that LEDs can detect the specific wavelength they emit, though questions were raised about their precision compared to dedicated sensors.

• The conversation covered genetic engineering advancements, specifically TALENs (Transcription Activator-Like Effector Nucleases) being used to edit zebrafish DNA, representing progress in custom gene editing technology.

• Users shared information about plant bioengineering, particularly carbon fixation processes in C4 plants and the challenges of engineering new plant anatomical structures.

• The NanoengineerOne software was discussed, with mentions that its developer Mark Sims was planning to bring the site back online rather than providing downloadable archives.

• MendelMax 3D printer project was highlighted for its use of FreeCAD Python scripts to generate CAD files, with GitHub links to the source code shared.

• Cognitive enhancement discussions included piracetam dosage debates, with reported effective doses ranging from 800mg to 4.8g, and some users reportedly taking up to 20g daily.

• A metabolic chart from Legendary Pharmaceuticals (by John Furber) was referenced in relation to SENS conferences, though participants noted its complex format.

• Potential science funding platforms were mentioned, including Innovocracy.org, though it was noted to have limited active projects with Cornell University involvement.
