- The channel tracked the rapid proliferation of colored-coin and decentralized-market projects, citing early examples BitMarket (via bittext.ch) and the BitShares white paper as reference points.  
- Participants analyzed the Coinye West legal case as a cautionary tale: the meme-coin’s developers pre-mined coins to fund a legal defense after Kanye West’s lawyers issued cease-and-desist letters, illustrating the legal risks of celebrity-branded cryptocurrencies.  
- A PNAS paper on Pleistocene Moroccan hunter-gatherers reporting early dental caries linked to starchy plant foods sparked debate; critics argued the study over-emphasized oral flora while ignoring fat-soluble vitamins, phytate-bound minerals, and counter-examples such as the high-carb but low-caries Kitava and Tokelau populations.  
- A DIY ultrasound specific-gravity sensor project was outlined, replacing an unsuccessful load-cell design with a 2 MHz ultrasonic transducer, 14-bit DAC, 100 MSPS 16-bit ADC, and FPGA-based real-time processing; hardware advice included favoring Class-AB over Class-A amplifiers to reduce crossover distortion and heat.  
- High-frequency analog design tips were shared, including warnings about collector-base capacitance in bipolar transistors at 2 MHz and suggestions for maintaining frequency response with basic test gear.  
- Open-hardware microfluidics research was advanced by manually mining Google Scholar for papers containing STL or other non-standard file types, aided by the channel’s paperbot, and a simple hand-actuated peristaltic pump (Thingiverse thing:13032) was highlighted as an easily-replicable lab tool.  
- Paperbot demonstrated its utility by retrieving pay-walled articles—including a Nature Nanotechnology paper on nanopore sequencing of single DNA molecules (doi:10.1038/nnano.2011.217), a graphene-nanopore DNA-detection study (doi:10.1038/nnano.2013.253), and a Springer microfluidics chapter—and storing them on diyhpl.us for open access.  
- Discussion on improving paperbot emphasized that returning debug or error messages is preferable to silence, and participants floated bug-bounty or direct-developer-payment models to fund continued development.
