Workshop / workspace organization tips

On the topic of workshop or workspace organization:
Just a tiny chapter in the Lean Book of Excellence is 5S.
A series of steps to achieve organizational excellence which very few ever attain.  It is not easy - it is time spent up front to lead efficiency ongoing.
So here is what 5S in its simplest terms -

#1 Sort - only keep what is needed. All else removed.

#2 Set - every item has a place where it lives. 
  • All like items in one place. 
  • Label drawers/cabins on the exterior because once you 5S everything you will get really frustrated by not being able to find what you are looking for.

#3 Shine - clean up and use methods for keeping sets/items like hand tools, etc. from rolling around. (foam storyboards, socket trays)

#4 Standardize - If more than one station/workbench, use the same tool -mfg./model - where possible.

#5 Sustain - implement a plan to keep #1 through #4 from dissolving back into the chaos from which it came. Mainly, At the end of the day/project everything is back in its place.

Once done, clutter should be a thing of the past. Zero searching around for that special tool.

How to Play Audio From Multiple Outputs in Windows 11

In testing, this doesn't significantly increase the volume of sound coming through monitor speakers via HDMI, but the sound does seem a bit clearer.  Using the headphone jack to drive proper speakers via a small amplifier is still preferable.

Advancements in synthetic skin could lead to better prosthetics

New Electronic Skin Communicates With the Brain Just Like Your Actual Skin (from FB):
A team of engineers at Stanford University has created a revolutionary soft electronic skin that communicates directly with the brain, mimicking the function of natural nerve signals.
Unlike previous iterations that rely on external devices, this next-gen e-skin senses temperature and pressure, converting them into electrical impulses similar to those sent by human nerve endings.
This innovation follows other cutting-edge projects, like a spray-on skin for gesture recognition and a smart bandage that monitors wound healing. Engineers at MIT and Graz University of Technology are also pushing the boundaries with sweat-proof e-skins and hybrid materials that detect temperature, moisture, and pressure.
The Stanford e-skin is made up of layers just nanometers thick, using materials like the rubber found in surgical gloves. The final product, supported by a substrate to maintain durability, is as thin as a sheet of paper. Operating at just 5 volts, the e-skin offers safe, sensitive feedback—potentially transforming prosthetics by providing a realistic sense of touch. Future goals include wirelessly transmitting these sensory signals to chips embedded in the nervous system, allowing prosthetic users to move their limbs naturally. With ongoing research focused on enhancing these capabilities, the Stanford team is inching closer to making human-prosthetic integration a reality.

US Special Forces Rifles

It appears that rifles developed in the 1980s, firing cartridges developed nearly a century ago are still what our Special Forces need.

One reason for keeping the large 50 caliber round is that it has enough room to fit explosives or incendiaries when they would be most effective.

There is (always) some talk of moving to a smaller round.  A bullet doesn't need to be a specific diameter to hit a target with sufficient energy to destroy it.  Also, cartridge cases can get smaller as propellants get more powerful and gun metals get stronger.  Small lighter cartridges make it easier to carry more rounds, but they need to be as effective (or more so) than the ones they're replacing.  This article is about different military rounds, but it makes the point:

I find it interesting that the current Barrett 50 caliber used by our troops is semi-automatic.  In civilian distance competitions, Barrett's bolt-action rifles in the same caliber are more accurate.  Perhaps the rate of fire (and the demands of urban combat) is nearly as important as it's accuracy in current combat scenarios.
