# Key Points from #hplusroadmap IRC Discussion

• Researchers discussed diamondoid mechanosynthesis requirements, noting that tooltip stiffness of 20 N/m is needed for precise molecular assembly, with 10 N/m providing positional uncertainty of ~0.02 nm at room temperature—sufficient for aligning molecular parts to within a fraction of an atomic diameter.

• DIY microfabrication was a central topic, with participants exploring projection photolithography techniques using microdisplays (TFT/LCD/LCOS) as reconfigurable masks, potentially achieving resolutions around 1 micron or 500nm with improved optics.

• A novel photoelectric metal deposition method was discussed that might combine photolithography and metal deposition in one process, potentially simplifying integrated circuit fabrication for DIY approaches.

• One participant described working on a startup developing an energy-efficient processor architecture for high-performance computing while simultaneously exploring DIY nanofabrication methods.

• SpaceX's announcement about plans to put humans on Mars by 2026 (approximately 10 years ahead of NASA) was shared and discussed among participants.

• Participants shared resources on DNA synthesis technology, noting that current costs ($0.10/bp) remain prohibitively expensive for large-scale de novo synthesis applications.

• Open-source scientific instrumentation projects were mentioned, including work on an OpenSpectrometer, demonstrating the channel's focus on democratizing advanced scientific tools.
