A short demo of an open-source Krita plugin that uses Stable Diffusion to generate and edit images in place. It adds ControlNet scribble and line-art support. You select an area, push a button, and new matching content appears.

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.

A demo of a raycasting 3D engine built entirely from in-game mechanisms in vanilla Factorio 0.17. It renders simple 3D scenes, producing a new frame every 45 game ticks, with the video sped up to compensate for low UPS.

Valve's short video on building the Steam Controller on a heavily automated assembly line, which the company designed itself. It shows the robotic manufacturing process and US final assembly.

Terry Davis, author of TempleOS, demonstrates his SimStructure physics simulator and builds a PID controller using math from Numerical Recipes in C. The description notes PID controllers are used in everything from rockets to espresso machines.

A TU Vienna demo of a double inverted pendulum on a cart, using constrained feedforward and optimal feedback control for swing-up and point-to-point motion.

LabCoatz uses mass spectrometry, with help from other science YouTubers, to reverse engineer the Coca-Cola flavor and builds a chemically-identical replica. The video walks through a year of work on the formula.

Fully Charged gets an exclusive first drive of the Porsche Taycan, running 0-200 km/h launch control repeatedly. It covers the car's twin-motor 800-volt specs, claimed range and fast charging.

A TU Wien control-systems demo in which a triple pendulum on a cart is swung up and stabilized using constrained feedforward plus optimal feedback control. It accompanies a 2013 Automatica paper.

Ben Heck modifies a keyboard with magnets, Hall effect sensors and an Xbox controller so the WASD keys give analog control. He walks through the hardware build.

Dashcam footage of a Tesla Model S on adaptive cruise control hitting a stopped van, with the driver listing the safety systems that failed to react. The uploader still calls the Model S the best car in the world.

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.

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.

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.

Nick Caston compares Unity's sample ECS/DOTS project (AngryBots) with his own from-scratch C++ and OpenGL clone. He benchmarks performance and discusses the effort involved in each approach.
