It doesn’t take too much to create a vortex in a bucket of water, but it’s still fun to see how just a couple of Technic motors and a few gears can be cobbled together can produce this popular physics demo. Those minifigs got to go for quite the ride when Brick Experiment Channel cranked things up to 11.
THE BEST Motors
While we’re perplexed by Liberman’s musical selections, we are impressed with what he was able to construct on his workbench. Watch as he puts together a working model of a helicopter rotor from plywood, rulers, popsicle sticks, and off-the-shelf hardware. We love how it even can adjust the angle of its blades.
The What’s Inside? channel presents one of its more costly videos, as they rip apart open one of the powerful drive motors from a Tesla Model S to see all of the gears, goo, and other goodies inside. This particular rear motor dates back to 2012, and was purchased off of eBay.
AmazingDIYProjects spent countless hours building this crazy loud electric flying contraption using dozens of drone motors. He captured footage of the marvelous machine’s maiden manned flight. Second flight starts at 15:30, and POV footage at 22:30. (Thanks Rob!)
Applied Science takes a look at an intriguing bit of tech that uses piezoelectric waves to move objects. This allows for low-profile, hubless, magnet-free motors and theoretically could create motors which aren’t round. The motor shown in the demo is from PCBMotors.
