- A participant reported that ICSPI’s nGauge AFM is priced at US $20–30 k even though its MEMS cantilever tip (the only complex component) costs only ~US $500; the company refuses to sell tips separately or to individuals, prompting renewed interest in completing an open-source AFM build.  
- The same participant noted that the nGauge integrates XYZ micro-actuators into the tip itself, making the extreme markup harder to justify and suggesting that a low-cost control board plus purchased tips could undercut the commercial price.  
- A link to “An Exercise in Dynamic Analysis” (https://windows-internals.com/an-exercise-in-dynamic-analysis/) was shared, likely for its relevance to reverse engineering or security research.  
- The GitHub repository “minicash” (https://github.com/phyro/minicash) was posted without further comment, presumably as a lightweight cryptocurrency or payment-channel implementation of interest to decentralized-tech researchers.  
- Discussion centered on the arXiv paper “Demonstration of Decentralized, Physics-Driven Learning” (2108.00275), which describes a network of variable resistors that autonomously trains itself in parallel, with projected 10⁶-fold speedups over simulation through modern fabrication.  
- Participants speculated about extending the resistive-network approach with nonlinear elements and hierarchical layouts built from semiconductor-decorated DNA-origami tiles, highlighting interest in self-assembling neuromorphic hardware.
