prototypes

Tested gets hands-on with four Meta Reality Labs research VR headset prototypes testing resolution, brightness, focus shifting and form factor, plus an interview with Mark Zuckerberg on display technology.

First of an 18-part lecture series by engineer Dan Gelbart on building prototypes. The series covers practical mechanical design and fabrication of precision machines.

The final part of Dan Gelbart's 18-part Building Prototypes series, focused on mechanical design. It opens with a demonstration of stiffness and covers practical design principles for prototype machines.

Part 10 of Dan Gelbart's prototype-building lecture series, covering flexures: flexible joints that give precise, frictionless motion. It shows how a cheap piece of aluminum can become a nanometer-accurate mechanism.

The first 3.5 hours of Tony Alicea's Udemy course on JavaScript's inner workings, covering topics such as first-class functions, closures, prototypal inheritance and how the language behaves under the hood.

A 1995 Sun Microsystems film about the Self programming language, a prototype-based Smalltalk relative, showing its live, graphical programming environment.

Bill Atkinson shows and explains his binder of Polaroids taken during Lisa development, documenting how its graphical interface evolved. Recorded at the Computer History Museum.

Dan Abramov's JSConf Iceland talk on what came after React 16, with live-coded prototypes of async rendering and time slicing. It previews the ideas that became concurrent mode and suspense.

Disney Research presents Touche, a swept frequency capacitive sensing technique that recognizes complex hand and body configurations, and adds touch sensitivity to humans, liquids and everyday objects.

Jensen Harris of the Office 2007 design team tells the behind-the-scenes story of the Ribbon at MIX08. He covers early prototypes, mistakes, and the UX principles used to design and validate it.

Declassified footage of 1950s tests of Project Orion, the nuclear pulse propulsion concept, including the Hot Rod prototypes flown on conventional high explosives. It shows the pusher-plate idea working in small scale.

A compilation of hover tests of exoatmospheric kill vehicles, the small rocket-propelled interceptors used in missile defense, including early prototypes from the late 1980s. It shows the vehicles maneuvering with thrusters in test facilities.

SpaceX's livestream of the Starship SN8 high-altitude test on December 9, 2020. It ascended, did the landing flip with flap control and reached the landing point, but touched down hard because of low header tank pressure.
