Behold, Shadowman39’s mechanical masterpiece. The appropriately-named Citadel is an imposing K’NEX great ball contraption that splits into 17 different paths. Shadowman says it took him a total of 1 year to finish, mostly building on the fly. More here.
It took quite a bit of planning and engineering prowess, but the end result of Daniel Perdomo’s recreation of Atari’s arcade classic PONG as a game played with mechanical paddles and ball cube is quite impressive. (Thanks Philip!)
Even today, computers error out if you try to divide a number by zero, but check out what happens with this old Facit ESA-01 mechanical calculator when posed with that mathematical conundrum. We’re assuming the death spiral was only ended by unplugging the cord.
Artist Graham Dunning demonstrates how to replicate sounds normally created with synthesizers and digital equipment, instead using a turntable, vinyl records, and mechanical and electrical devices in their place. The whole thing gets pretty bonkers by the end.
This intricate, pneumatic-powered LEGO Technic model built by Huib van der Hart replicates the inner workings of a V-8 engine – and is nearly as loud as one – so you might want to turn your speakers down for this one.
Brickride’s impressive build uses 100% LEGO components to create a fully-functional rollercoaster, complete with a loop and a corkscrew. See a time-lapse of the build here. Check out one of their earlier coasters here.
Inspired by the Theo Jansen’s incredible Strandbeests, these die-cut cardboard animals have legs that can actually walk when your turn a crank. A motorized option is also available, so your menagerie can actually walk on their own.
A look at the mechanical wonders of a Porsche Carerra 3.2 Engine as told through a time-lapse of an old engine being torn-down for restoration over the course of three months by Hoing Motorsports. Shot by Filmkooperation.
Obsessive LEGO builder Solde created this palm-sized replica of the 4A-GE engine found in Toyota’s MR2, complete with working timing belt, crankshaft, pistons and throttle. We’re guessing it doesn’t really make those sounds.
