- Preliminary neuroimaging studies show consistent alterations in brain networks governing body-ownership and self-perception in trans individuals, and the desire to transition appears immutable once established.  
- Evidence cited indicates that regret rates among adolescents who receive puberty blockers or early hormone therapy are “close enough to zero as to make no difference,” while untreated gender dysphoria rarely remits.  
- Discussion framed puberty blockers as a comparatively low-risk intervention and, half-seriously, speculated whether delaying puberty for the general population might yield cognitive benefits.  
- A CHI’22 project, “Print-A-Sketch,” was highlighted: it uses a ~US$220 Xaar 128 piezoelectric printhead and commercial nanosilver ink (Metalon JS-A102A) to inkjet-print circuits onto arbitrary surfaces, with links to the project page and full paper provided.  
- Xaar’s corporate stance was reported as hostile to open-source use; their Nitrox heads handle UV-curable (higher-viscosity) inks but cost ~US$10 k, spurring calls for industry disruption.  
- Participants brainstormed hybrid fabrication schemes combining inkjet metal traces with coarse SLA/FDM-style UV curing to build multilayer boards without prohibitive equipment costs.  
- Hackaday coverage of Print-A-Sketch was shared, noting that short test traces were printed to conserve the scarce conductive ink.  
- The open-source CAD kernel Fornjot (GitHub: hannobraun/Fornjot) was recommended to lsneff as a potential building block for custom printer control software.
