# Key Technical Discussions from #hplusroadmap

• The Center for PostNatural History was highlighted as a museum dedicated to organisms modified through selective breeding or genetic engineering, representing an interesting intersection of biology and human intervention.

• DIY laboratory equipment was a significant topic, including converting slow cookers into sous vide machines or incubators, with detailed discussion of pH electrodes and temperature controllers for cost-effective lab setups.

• Participants shared sophisticated technical knowledge about using PIN photodiodes to detect X-rays through bremsstrahlung radiation, specifically for monitoring the thickness of holes being machined by ion beams in metal.

• Several analytical chemistry techniques were compared, including anodic stripping voltammetry (ASV), potentiometry, and mass spectrometry, with reference to the CheapStat open-source potentiostat project that enables affordable electrochemical measurements.

• The conversation included detailed comparisons of parallel computing architectures, distinguishing between GPU's SIMD (Single Instruction, Multiple Data) processing and the Epiphany processor's MIMD (Multiple Instruction, Multiple Data) approach.

• Microfluidics was discussed from multiple angles, including a LEGO-inspired system and plans for creating devices for cell observation using separate chips for mixing and observation, with mentions of manufacturing collaborations in Thailand.

• Hardware security research tools were referenced through the ChipWhisperer-Lite Kickstarter project, indicating interest in open-source approaches to security testing and analysis.
