This ball circuit takes approximately eight minutes to complete, with balls getting lifted on ferris wheel, dumped from a truck, moved on a train, there’s also an excavator and bulldozer, a stair-master of sorts, Pachinko, and just about every way you could imagine moving balls. All of this is done through entirely mechanized Lego blocks, a little ingenuity, some gravity, and a hell-of-a-lot of timing.
Unfortunately, ctx0075 does not leave any information on how it was built or how long it took. The YouTube video description only contains a single question in Polish; “Marzenie każdego dużego chłopca?”--that roughly translates to “the dream of every big boy?”
Ctx0075 has a few other videos of his Lego creations, including a pneumatic Lego spider walker that looks a lot like the mechanical menace from the movie Wild Wild West. Apparently, these mechanical Lego ball-moving contraptions are everywhere. A quick YouTube search on “Lego ball machine” brings up about 1,240 results and there’s a whole community/movement behind it called the LEGO Great Ball Contraption.
