Celestial Sphere: the Stars of the Night Sky

Created by Clemens & Christoph of CinkS labs: Available in a cube too! 
From CinkS Labs: BUY NOW: Celestial Spheres

Celestial Sphere: the positions of 5068 stars as they appear in the night sky- along with 88 constellations, laser etched into a crystal sphere. This globe includes all stars of sixth magnitude or brighter- basically all the stars that the average and unaided human eye can see in the sky. The Milky Way in a Sphere: the distribution of stars in our home galaxy, laser etched into a crystal sphere, according to the most recent telescopic surveys and mappings- including the stars in the Sagittarius Dwarf Galaxy (a small galaxy that is simultaneously orbiting and getting absorbed into the Milky Way) and the major globular clusters outside the main disk

Zoetrope: the physics and psychophysics of motion animation- still images flashed in rapid succession produces the illusion of motion through persistence of vision. The slits are crucial to creating the illusion by blacking out the visual stimulus for a short duration- without these pauses only a blur is perceived. When the image flash rate is above the flicker fusion frequency (approximately 16Hz) we perceive fluid motion- the basis for all movies and TV. 

Curie Point Heat Engine

This DIY project is pretty easy to build. One half of one of these inexpensive magnetic necklace clasps will work well for the heated magnet.

Curie Point Heat Engine: when the magnet on the end of the wire heats up to a particular temperature (the Curie point) its magnetic field is temporarily lost until it cools. This engine design uses a second magnet to pull the swinging magnet back into the heat source once the magnetic field is reestablished. Repetition of this process creates mechanical motion as long as the heat source is fueled.

Nixie Tube Clocks 

Nixie Tube: long before there were 7 segment LED displays there was the Nixie- cold cathode tubes with a wire mesh and 10 cathodes shaped in the form of numerals 0-9 that illuminate through neon glow discharge. The “Numeric Indicator eXperimental 1” or NIX 1 was introduced in 1955 by Burroughs Corporation and manufactured until the 1990s. This clock uses modern electronics to power Russian versions called the ИH-19A where the numbers are stacked so the front symbols obscure each lighted cathode minimally: from back to front 1320984756.
