TL;DR
Video of a Lego project featuring many gearing solutions.

Yeah, saw this. Super cool.
Would make a neat educational project.
 
I saw another one where the youtuber recreated a 2 bit digital computer with lego parts modeled on the 1960's Digicomp I toy computer.

But this one definitely takes home the prize for beautiful lego design and beautiful videography.

Some guy built a working virtual PC inside Minecraft.

Which is cool enough, but he can actually have the virtual PC run a game of Minecraft, and play Minecraft within Minecraft.

IncepMinecrafttion! :spooky hands:

Nice, I did something similar years ago at work. We were working on Apple Opendoc porting it to IBM OS/2.

Its key feature was the ability to embed parts into a document. I built a tictactoe part where each square was a tictactoe part basically creating games within games within games. A win of an embedded game resulted in winning an X or O for the square.

I won an internal award for it as one of the top five OpenDoc parts out of a total field of 5 competitors.

The first one is a Schmidt coupling. It's an actual useful product for applications such as driving a roll that needs to move while under load: https://www.zero-max.com/aca-schmidt-offset-shaft-couplings. Screen shot from the Zero-Max link:

Their largest catalog coupling is rated for 459,000 in-lbs (51,900 Nm) torque.

Interesting factoid about them: They only work when misaligned - when the shafts are offset by a minimum amount.

I suppose that makes sense if you think about it.

If I tried to spin a bicycle wheel using a broomstick handle, I would have a tough time starting it spinning if I stuck it in too close to the axle. Not enough leverage. I'd move father out.

Not really. There is a Minecraft mod which wraps VirtualBox so you can run a virtual machine inside Minecraft, but that is not a PC built inside Minecraft.

It's a bit like calling one of these a Raspberry Pi built out of Lego https://thepihut.com/products/blox-raspberry-pi-case

Edit: I would call this a computer built inside Minecraft:
And this a computer built from Lego

Ok. I may have to take your word for it. I thought this guy had literally built an operating PC with memory and all in the Minecraft world.
 
I have constructed many LEGO apparatuses for physics demonstrations. I am thinking about writing about them in english and share on the forum in the future :)

Yes this does exist: Chungus 2 (Computation Humongous Unconventional Number and Graphics Unit) has an 8 bit CPU and 256 bytes of RAM: this is not enough for Minecraft.

There are also a number of "minigames" that have been built in Minecraft including a 32x32 pixel sort-of version of Minecraft: https://codecrafted.net/#/r/minigame/452, but this is all custom built, it is not a virtual machine running Minecraft.

Damn, that would be cool. Signing up.

Also: heaven is bringing home a stack of LEGO kits and saying "Sorry honey, it's for work. 🤷 whaddyagonnado!"
