LEGO 1×1 Gear Train

LEGO 1×1 Gear Train

Today’s most satisfying video comes in the form of this clip from the Brick Experiment Channel. Their goal? Create the longest possible chain of 1×1 LEGO Technic gears while retaining the same gear ratio from start to finish. We’re impressed that a single motor can drive that many gears.

Making a Supercapacitor Electric Bike

Making a Supercapacitor Electric Bike

Supercapacitors have one big advantage over batteries – they charge much faster. But they also discharge energy more quickly, limiting operating range. This makes them suboptimal for EVs. Engineer Tom Stanton built a supercapacitor pack and drive unit for an E-bike to see just how it stacks up to battery power.

Turbine Umbrella Hat

Turbine Umbrella Hat

Maker Ivan Miranda lives in a beautiful place in Spain. But he hates when it rains there, and he doesn’t like carrying an umbrella. So he set about the task of engineering a motorized helmet that uses a powerful motor and a turbine to blow the rain away from his body. And yes, it works in real rain.

PacMotor Dual Kayak Motor

PacMotor Dual Kayak Motor

The PacMotor lets you enjoy kayaking without physical exertion. Its adjustable frame attaches to the rear of most kayaks, propelling a 7.5-foot kayak up to 6 mph. Its two motors steer with a waterproof remote joystick controller, and its props can be lifted out of the water when you want to paddle, or when getting close to land.

LEGO V12 Engine @40,000 RPM

LEGO V12 Engine @40,000 RPM

LEGO builder Mad Brick created a working replica of the block, crankshaft, and pistons of a V12 engine. Then he lubed it up and connected the engine to a powerful motor, which spun up to as much as 40,000 RPM. It worked great until the pistons started flying.

32 Stepper Motor Orchestra

32 Stepper Motor Orchestra

A 32-piece orchestra needs need a pretty big stage for all of those musicians and their instruments. Jonathan Kayne has solved this problem by replacing those pesky humans with stepper motors. The members of his band never talk back, and they play everything from All-Star to Piano Man to The Mandalorian theme.

LEGO Water Vortex

LEGO Water Vortex

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.

Desktop Helicopter Rotor

Desktop Helicopter Rotor

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.

What’s Inside a Tesla Motor?

What’s Inside a Tesla Motor?

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.

Mendocino Levitating Motor

Mendocino Levitating Motor

Physicsfun presents a brief demonstration of one of the more interesting motors we’ve seen – the Mendocino motor uses magnets and a solar energy source to levitate as it spins. You can pick up a similar version for your own desk over on Amazon.

Manned Multirotor Flight

Manned Multirotor Flight

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!)

Piezoelectric Motors

Piezoelectric Motors

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.
