pid controller

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.

The Thought Emporium shows how they engineered a yeast strain to produce real spider silk, after more than two years of lab work and many failures. The video explains the genetic engineering process behind it.

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.

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.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

Ben Vallack compares finger movement on a staggered keyboard with an ortholinear grid keyboard, using an Anne Pro 2 and a ZSA Planck EZ. He argues the stagger forces awkward finger motion.

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 35-minute demonstration of NeXTSTEP Release 3 by Steve Jobs. It shows the object-oriented development environment and features such as dragging a live chart between apps.

A three-minute demo of ProFORMA, a system from Cambridge that builds textured 3D models live from a video of an object.

A live performance at AGDQ 2014 in which Super Mario World is made to execute arbitrary injected code, running other games like Pong and Snake on the cartridge. It is done through a TASBot feeding precise controller inputs.

SethBling uses Super Mario World glitches to inject and run Flappy Bird code on an unmodified SNES, entering it purely with controller inputs. It was the first time a human completed this kind of exploit by hand.

A recording of the TASBot block at Awesome Games Done Quick 2017, where a robot plays games via tool-assisted speedruns, including Super Mario 64 and Portal on an SNES via arbitrary code execution, and ending with a Twitch Plays segment. It showcases console exploits and creative hardware hacking.

John Carmack live-codes a simple VR application at Oculus Connect 2 using a Racket-based environment for rapid development and deployment on Gear VR.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

A tool-assisted speedrun of Pokemon Yellow on Game Boy Color that uses glitches and frame-precise inputs to make the game execute an arbitrary program. It was later obsoleted by an improved run.

A short demo of typing on the Modos Paper Monitor, an open e-ink monitor, using 4-level grayscale to show low latency.

A demo of Brigade 3 real-time path tracing at 720p controlled with an Xbox controller. Depth of field, field of view, reflections and shadows can be altered live.

A 2013 research demo of simulated bipedal creatures whose natural gaits are found by optimizing muscle-based controllers, with no motion capture or keyframe animation. It shows physics-based walking and running emerging from musculoskeletal models.

A short Bookeen R&D demo showing smooth H.264 video playback on a Pearl E Ink panel, driven by a TI OMAP3621 chip and custom controller software.

A short clip of Bill Gates demonstrating Visual Basic in 1991, showing drag-and-drop building of a Windows GUI.

A tool-assisted speedrun of Super Mario World that achieves arbitrary code execution through frame-precise controller inputs, finishing in 2:25. It was also performed live on real hardware at AGDQ 2014.

A demo of the Bad Apple music video played back at 60 FPS on an e-ink display, up from 2.4 FPS in an earlier attempt. It is part of the effort behind the open source Modos e-ink monitor.

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