- A new ASIC design for faster SHA-256 hashing was discussed, based on “carry-reduced adders” that promise higher Bitcoin-mining throughput (bitslog.wordpress.com article).  
- Long-term, low-frequency heat-stress patches (8 h/day, 4 days/week for 10 weeks) were shown to increase human quadriceps strength ≈5.8 % and muscle cross-sectional area without exercise, accompanied by up-regulation of oxidative-phosphorylation genes such as UQCRB (cited paper: Journal of Physiological Sciences).  
- Neuromuscular electrical-stimulation literature was reviewed: Russian medium-frequency burst-modulated AC fails to reach voluntary-maximum force, whereas low-frequency burst-modulated AC can; currents of 25–100 mA were noted as typical ranges (papers from Physical Therapy and Informa Healthcare journals).  
- Open-source vehicle development efforts were compared: juri_ is reverse-engineering the Velocar for fully printable parts while criticizing Local Motors for keeping designs and printer specs closed; the OSVehicle Nika was mentioned as weatherproof but not yet open-source.  
- Metal printing capabilities were debated: conductive inks, MIM feedstocks, jewelers’ clay printers, industrial powder-sintering, and juri_’s own “print-to-cast” workflow were all cited as routes to functional metallic parts (guns, engines, door handles).  
- A high-throughput “maskless” multi-electron-beam direct-write lithography system (MEBDW) was highlighted, claiming >50 8-inch wafers/hour at 100 nm/70 nm nodes without photomasks (ftp-linked PDF from JVST).  
- DIY sensor-networking resources were shared: MySensors.org project and its GitHub repositories for low-cost home/health monitoring hardware and firmware.
