A two-minute demo of SmartKnob View, an open-source input knob built from a brushless gimbal motor, magnetic encoder and round LCD. Closed-loop torque control gives software-defined detents and end stops.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

A short MIT Aerospace Controls Lab demo from 2011 of a variable pitch quadrotor flying.

Matthaeus Krenn presents a concept for car touchscreen UI where the screen controls only one thing at a time, designed to suit driving. A tablet prototype accompanies the short demo.

Marco Reps builds and tests an open-source 8.5 digit voltmeter based on CERN's high-precision ADC design. The video walks through assembly, soldering and measurement of the resulting instrument.

A controlled demonstration by Wabash National of a tank trailer collapsing under vacuum, staged at an industry expo. The tank implodes as air is pulled out.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

An old lab video of a decerebrate cat walking on a treadmill and shifting between gait patterns as the speed changes. It is used to illustrate that much locomotion control comes from the spinal cord and body mechanics rather than the brain.

Casey Muratori follows up his refterm proof-of-concept, a GPU-based terminal renderer, with a second part covering memory usage, glyph sizing and correct Unicode and VT handling. It is built to show that a terminal can be fast and correct without heroic effort.

Zack Freedman introduces Gridfinity, his free, open-source modular workshop storage system of 3D-printable bins and baseplates. The video walks through the design, the parametric templates and the many module types that fit parts, tools and accessories.

HERO is a short animated film made entirely in Blender to showcase the Grease Pencil 2D animation tools in Blender 2.8. It mixes hand-drawn 2D with a full 3D pipeline.

A short clip of a Renault F1 engine playing God Save the Queen by precisely controlling its RPM, recorded at Goodwood. It demonstrates how finely the drivetrain can be controlled.

Smarter Every Day host Destin Sandlin tries to hover a helicopter and finds it very hard. The video shows how the constant coordinated corrections across several control axes feel at first and how learning makes them automatic.

A demonstration of Larynx, an offline open source neural text-to-speech system supporting nine languages. The video itself is narrated with a Larynx-generated voice.

A short Bookeen R&D demo showing real-time web page scrolling on an eInk panel, far faster than typical e-readers. It was a prototype for the next generation of Cybook readers.

Short US Missile Defense Agency footage of the December 2008 free-flight hover test of Lockheed Martin's Multiple Kill Vehicle. The test showed it hovering for 20 seconds while tracking a simulated target.

A short Boston Dynamics clip of the Atlas humanoid robot doing parkour, jumping over a log and leaping up steps using whole-body control and computer vision to locate markers.

A demonstration from UPenn's GRASP Lab of an autonomous quadrotor performing flips, flying through windows and perching on surfaces. It shows precise aggressive maneuvering control of a small UAV.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.

ETH Zurich researchers demonstrate a quadrocopter that keeps flying stably after losing a motor and propeller entirely, with the algorithm running onboard while a pilot flies it.

A demo of the Cubli, a 15 cm cube that uses reaction wheels to jump up onto a corner, balance there and fall in a controlled way to move. The video shows these three abilities chained into locomotion.

Road & Track puts a 2014 Porsche 911 Turbo through 50 back-to-back launch-control runs on a SoCal runway. The car completes 61 launches before the testers lose count.

A Waymo clip, sped up 3x, showing its autonomous car stopping at a broken traffic light and proceeding on a police officer's hand signals.

Boston Dynamics shows its Atlas humanoid robot performing a gymnastics and parkour routine, using optimization-generated motions and a model predictive controller.

A short hyperlapse of a 2019 Toyota Corolla using comma.ai's OpenPilot 0.6.3 to drive 100 miles with no intervention except for the windshield wipers.

Cockpit footage of a Swiss Airbus A340 crew dealing with rising oil temperature in one engine on a Zurich to Shanghai flight, ending with a safety landing. It shows the pilots' procedures through the emergency.

Mark Rober shows an automatic bullseye dartboard that tracks a thrown dart with motion capture and moves in real time so it always hits the center. He spent over three years on the project.

The author of lazygit demos 15 features of his terminal UI for git, such as staging individual lines and easier rebasing, aimed at making common git tasks simpler.

Hobbyist Wesley Kagan shows his Miata running and driving with a homemade version of Koenigsegg's freevalve camless valve technology. The build uses open CAD files and code and he describes it as an ongoing work in progress.

Joe Barnard of BPS.space shows his model rocket Scout F landing vertically like a SpaceX booster after seven years of attempts. The video documents the successful landing and the build-up to it.
