- A user successfully transported a Focused Ion Beam (FIB) microscope into a home garage using a rented forklift, noting the machine’s 200–240 V, 16 A power requirement and estimating 5–15 minutes for initial pump-down after power-up.  
- Discussion of FIB consumables: the gallium liquid-metal ion source is rated for 1 000 hours and currently at end-of-life; vendor quotes for replacement/refill range from US $3.7 k to US $8 k, prompting interest in self-refilling with 99.9999 % gallium available from Sigma-Aldrich for ~US $66/5 g.  
- A TechCrunch article on the “Turing Tumble,” a mechanical marble-based computer kit, was shared as an educational tool for demonstrating logic gates and computation without electronics.  
- A relativistic “time-travel” concept was floated: continuously accelerate a spacecraft within the solar system and hope future propulsion advances allow later deceleration, despite exceeding escape velocity.  
- Links circulated: US Department of Labor apprenticeship toolkit PDF, Japanese Wired article on the film “Blame!”, and an open-hardware security-module campaign on CrowdSupply.  
- Research paper shared: “Quantum chemical insights from deep tensor neural networks” (arXiv:1609.08259) for accelerating molecular-dynamics simulations with machine learning.
