problem statements

A BBC Earth clip from Inside the Animal Mind in which a crow named 007 solves an eight-step puzzle to get a reward. It showcases crow problem-solving.

Dave Jones of EEVblog investigates why a 4K BenQ monitor switches itself off, tracing it to static discharge from an office chair. He uses an oscilloscope to examine the static impulses.

Big Clive tears down a smart meter with a wireless modem found among fly-tipped materials. He examines its internals and checks conspiracy claims about microphones, cameras and 5G.

Mark Rober visits Zipline and looks at its autonomous delivery drones, including medical and blood deliveries in Rwanda. He demonstrates how the drones' propeller design and cable-lowered delivery pod make them quiet and precise.

Casey Muratori gives a fast tour of the RemedyBG debugger for Windows, which he uses daily. He shows its speed and features, especially the watch window.

Tom Wildenhain's SIGBOVIK 2018 presentation of WordTeX, a Microsoft Word template that mimics LaTeX typesetting output. It is a joke research project executed with serious effort.

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.

Maker's Muse designs a 3D-printed and laser-cut puzzle box to test whether wild sulphur-crested cockatoos can solve it. He documents how the birds work it out.

A short preview of OTOY's Brigade 3.0 engine doing real-time path tracing, running on two GTX Titans.

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.

A short video arguing that the iPhone keyboard has gotten worse, showing slow-motion footage of taps registering the wrong letters. It claims the problem is iOS itself rather than user error.

A SIGGRAPH 2013 demo from Douglas Lanman and NVIDIA of near-eye light field displays, which allow much thinner head-mounted displays that still show accurate focus and depth cues.

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.

A DevOps YouTuber tests GitHub Copilot on a range of Leetcode problems and finds it solves most immediately, with a few needing tweaks and some far off. He concludes it would outperform him in a FAANG-style interview.

Sean Hodgins shows the build of the Arduino-based glitter bomb package-theft trap he made with Mark Rober, covering the electronics and the problems that came up. The code and schematics are on GitHub.

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.

A Fully Charged episode on Ubitricity, a German company that turns ordinary street lamp posts into roughly 5 kW overnight EV charge points, with a locking cable and managed billing.

Adam Savage builds a Victorian-style rickshaw carriage for Boston Dynamics' Spot robot to pull, with him riding as passenger. The video covers the build and the engineering problems of pairing cutting-edge robotics with vintage transport, such as tuning the payload through Spot's API.
