Much respect to the software engineers out there. I was recently reminded of r/itrunsdoom (which has gone dark indefinitely) and thought I'd share an example I once found there.

Have you worked in remote areas, restricted sites, or just unusual places that most people don't get to see? What was it like?

The build process is very cool, but if you just want the sweet eye candy then skip ahead to the 12-minute mark.

PrimeCuber is a Rubik's cube solver built using a Lego Spike Prime kit. The mechanism to flip/hold the Rubik's cube is really slick, using a single motor and a 5-bar linkage. The link includes a video showing the mechanism in action, as well as build instructions and downloadable code.

Hi, I want to learn ANSYS, especially Fluent. Do you guys know of any good youtube channels or recommendation for inexpensive online courses?

Thanks!

I'm not a submarine engineer, but I would have expected that some of the more complex systems would have failed before the pressure vessel. Then again, it seems like they chose a seemingly cost effective design that was apparently susceptible to fatigue. Combine that with a profit motive to dive as many times as possible before retiring the hull and I suppose an implosion was practically inevitable. Oh well.

This video does a good job of visualizing the intricate mechanisms inside an internally-geared bicycle hub.

Edit for phrasing.

Combining machining, lost wax, and electroplating to make a miniature copy of the Space Shuttle's combustion chamber.

Edit for spelling.

As the inaugural post, here's a great introduction to how GPS works. It starts with the basic physics and moves to implementation details, including some of the signal processing.
