These are a couple videos highlighting the journey of father/son team Mike and Luke Bell as they attempt to reclaim the world record for fastest quadrocopter drone after their record was snatched from them last year. There’s a lot of interesting discussion about the engineering and testing of the drone,

This is a video following LEGO builder Grant Davis’s quest to construct a working mechanical version of the bouncing DVD logo screensaver using LEGO. And what a quest it is! If somebody asked me if you could make a working DVD logo screensaver out of LEGO I would have told

Because dream it and you can kinda sorta make it happen occasionally, this is a video of mad inventor/engineer Allen Pan (previously) building two different versions of automatic trick-performing skateboards. The first is powered by drone rotors and isn’t great (note: he should revisit this build for making a hoverboard),

Because some people actually bother putting their know-how to good use, this is a video of Youtuber Engineezy building and playing a physical version of the Flappy Bird video game. It’s a very impressive build, featuring pipes that rotate on a conveyor belt, randomly adjusting their height as a player

Because there’s nothing you can’t do with LEGO, this is a video from the Brick Experiment Channel (previously), this time engineering LEGO cars to cross increasingly narrower bridges, eventually crossing just a string stretched between two tables. The solutions to balancing the vehicles while crossing the bridges are quite ingenious.

Inspired by The Q’s previously posted bicycle version, Sean Kerr and friends at Youtube channel Bikes And Beards decided to try building a motorcycle with a split back wheel. They do an okay job, but I’ve got the feeling they didn’t build the bike with the same precision engineering as

This is a video of engineer and tinkerer JBV Creative constructing ‘The Corporate Machine’, a piece of kinetic wall art for his apartment that represents the tireless churning of big business. Using 99% 3D-printed parts, the machine launches ping-pong balls and catches them, repeating the process indefinitely until a power

This is a video of ex-NASA engineer Mark Rober (previously: his new and improved anti-porch pirate glitter bomb) constructing the world’s most powerful t-shirt cannon at the request of Jimmy Kimmel for use at the Jimmy Kimmel LA Bowl game of Oregon State vs Utah State. Mark enlisted the help
