quantum computers

A short demo from Tel-Aviv University of a superconductor locked in a magnetic field, hovering and staying fixed in place. It was shown at the 2011 ASTC conference.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

A short demo of a walking droplet on a vibrating silicone oil bath passing through a double slit and producing interference, a macro-scale analogue of pilot-wave behavior.

A short 2009 amateur video showing an HP MediaSmart webcam whose face tracking follows a white face but fails to track a black face. The uploader presents it as humorous.

Dave Jones of EEVblog tears down a Kollsman MD-1 Automatic Astro Compass, a mechanical analog computer from a B-52 bomber. It is part of a star-tracker inertial navigation system that computes altitude and azimuth.

The 8-Bit Guy reviews the Color Maximite 2, a modern ARM-based computer that boots straight into BASIC. He shows what it can do as a retro-style machine.

A showcase of the author's fifth-generation quad-core computer built entirely from Minecraft redstone, after two years of development. It features cache, a hardware stack, a GPU driving a 15x15 display, and serial I/O ports.

A short clip of the Harwell Dekatron/WITCH, the world's oldest original working digital computer from 1951, being restarted at The National Museum of Computing in 2012.

A demonstration of loading Altair 4K BASIC on an Altair 8800 clone, using a front-panel bootloader and an ASR-33 Teletype. It shows the full sequence of entering boot code, loading BASIC and running a program.

A short demonstration of the MONIAC, Bill Phillips' hydro-mechanical economic computer, at the Reserve Bank of New Zealand museum. It shows how water flows model an economy's money flows.

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