A short clip showing a person touching an active table saw blade with a finger and walking away unharmed, thanks to SawStop's system that stops the blade within milliseconds of skin contact.

Matthias Wandel shows his wooden machine that adds binary numbers using marbles. It demonstrates computation with purely mechanical logic.

SethBling shows MarI/O, a program using neural networks and the NEAT genetic algorithm to learn to play Super Mario World. The description links the source code, the paper and background reading.

Mark Rober and Jabril build an app that uses machine learning to decode baseball sign sequences. The video also explains neural networks in a simple, accessible way.

A short demo of the Deep Visualization Toolbox, which shows the activations inside a convolutional neural network as it processes live camera input. Viewers see individual units responding to edges, faces and text.

Microsoft Research's Rick Rashid demonstrates a speech recognition and translation system, built on deep neural networks, that turns his spoken English into Chinese speech in 2012.

A six-minute journey through the layers of a neural network using Deep Dream, with each frame fed back into the network starting from random noise and the targeted layer changing every four seconds. It is set to downtempo music.

A short video accompanying the CVPR 2018 paper Learning to See in the Dark. It shows a neural network producing sharp images from very low-light raw sensor data, compared against denoising approaches.

A short video from a blacksmith, who heats and bends steel to rebut the claim that jet fuel could not weaken the steel in the World Trade Center. It is delivered with a lot of attitude.

A 47-minute restoration of a 1920s IBM computing cheese cutter, a machine with parts patented between 1901 and 1907. The video covers the restoration work and explains why it is a computing cheese cutter.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

David Heinemeier Hansson builds a blog engine with Ruby on Rails in 15 minutes, the demo that launched Rails' momentum.

A video presenting an Intel research paper on enhancing the photorealism of synthetic images. A convolutional network uses rendering intermediates, shown on GTA V footage that comes out looking like real street scenes.

Excerpts from W. Edwards Deming's Red Bead Experiment, where workers draw beads from a bowl and are judged on red ones that are largely down to chance. It shows how system variation, not individual effort, drives results.

Tom7 (suckerpinch) builds and evaluates a series of absurd hard drives, including storage made from ping packets across the internet. The video accompanies his paper and mixes deep technical hacking with comedic storytelling.

Primitive Technology shows building a cord drill from scratch and then upgrading it to a pump drill, using only primitive materials like a stone flywheel and cord.

Juan Benet gives an overview and demo of the go-ipfs alpha. It shows the peer-to-peer content-addressed protocol in action, including streaming video from a home computer.

A LockPickingLawyer video in which a locksmith claims his videos are fake and challenges him; he responds by picking the lock. It is a short, typical LPL demonstration.

A Primitive Technology episode in which the creator builds a bow-drill-driven bark fan to blow air into a fire, using only natural materials. It shows the progression from fanning a fire by hand to a rotary forge blower.

Dan Gelbart shows his home-built air bearing CNC lathe and grinder, which reaches about 1 micron accuracy. He demonstrates the machine and its parts.

The Primitive Technology channel shows the making of a stone axe (celt) using only primitive tools and materials, from shaping and polishing a basalt head to making the wooden handle and hafting it.

LockPickingLawyer shows a Sentry fire safe being cut in half with a saw in a few minutes. It is a short demonstration that these safes offer little protection against a determined thief.

CNLohr maps Wi-Fi signal strength at high resolution by moving an ESP8266 on a CNC mill, then visualizes the 3D data in WebGL. The result shows interference patterns in space.

The creator of ESPARGOS, an ESP32-based antenna array from the University of Stuttgart, explains how it senses phase and amplitude of WiFi signals to localize devices and build a WiFi camera. It demos the Python library and project.
