prototypes

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.

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.

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.
