Because who likes changing gears to make climbing hills easier anyways, this is a video of Sergii Gordieiev of Youtube channel The Q replacing a bicycle chain with a series of 3D printed gears, effectively making it a single speed. So is that an upgrade or a downgrade? I suppose

This is a video of Youtuber Matt Denton constructing an electric powered, 3D printed parts replica of the 1981 LEGO Technics Dune Buggy set 8845. It’s 10.5x larger than the original, so large Matt is able to sit in it to drive. That’s cool, but you can sit in anything

Inspired by LEGO’s 2021 typewriter set, which did not type, Youtuber Koenkun Bricks took it upon himself to make a version that actually works. And it does, just not how a traditional typewriter does. The mechanism is very impressive, and I’m blown away (FULL DISCLOSURE: I am like a dandelion

PROTIP: Keep your volume low. Possibly muted entirely. These are a couple videos of musician Honest Kevin (IS HE THOUGH?) of Moon Armada performing with his ‘baby bot noise ensemble’. And what a noise ensemble it is! If I was forced to listen to this any longer than it took

This is a video documenting Youtuber The Lab-X’s quest to build an AI-powered water turret to keep his cat Cookie off the kitchen counter. The 3D printed bot, named Puffy, uses computer-vision to track the cat’s movement and spray him when he’s detected on the counter. Lab-X plans to sell

Inspired by AI slop images, engineer Allen Pan (previously) decided to try building an aquarium toilet in real life. The result? A surprisingly functional aquarium toilet. If I’d tried building it? An unsurprisingly unfunctional aquarium toilet and $18K of water damage in the basement. BONUS AI slop beer boots made

This is a video of LEGO experimenter Brick Technology (previously) pitting LEGO cars against increasingly larger loopty loops. It was a fun watch with surprisingly high production value, and this is the exact sort of experimenting I wish I spent my weekends doing. But nooooo, I spent the entirety of

Because why buy 2-liters of Coca-Cola when you can spend a whole year and small fortune trying to make it yourself at home (do Mentos next!), this is a video documenting engineer Zach Armstrong’s quest to replicate the exact Coca-Cola formula. Zach uses mass spectrometry to determine the chemical composition
