AntiKythera Mechanism out of Legos

Friday, December 10th, 2010

Apple engineer Andrew Carol pieced together 1,500 piece Lego Technic blocks to build a faithful-in-function replica of the Greek Antikythera Mechanism. Though built in ancient times (150-100 BC) it’s thought to be of comparable sophistication to 19th century Swiss clocks.

Discovered in a ancient shipwreck in 1901, it took researches decades to discover its intended purpose – as an astronomical calculator capable of predicting eclipses, the positions of the sun and moon, other planets and significant stars. It’s widely considered the first known mechanical computer.

Acid Machine

Wednesday, October 15th, 2008

Gijs Gieskes has made many wonderful machines from gameboys or other machines which he’s circuitbent.

He writes about the Acid Machine:

The circle with the lines that you see on the top of the machine, rotates and displays the note you are playing.
When you play a C the lines in the middle circle will be standing still.. from the C it will go outward, displaying all notes on a keyboard in 12 steps.

It works by making a LED blink in the frequency of the sound, and rotating the image at a set speed.

Using Photographs to Enhance Videos of a Static Scene

Using Photographs to Enhance Videos of a Static Scene from pro on Vimeo.

Students at the University of Washington have produced impressive software to enhance video in several ways by introducing higher resolution/higher dynamic range photographs into the workflow:

The work presents a system for automatically producing a wide variety of video enhancements and visual effects. Unlike traditional visual effects software (e.g., look After Effects, Shake, Boujou, etc), the system is completely automatic and no manual labor is required from the user. The major limitation of the work is that it can currently handle only videos of static scenes (i.e., videos shot with a moving camera but containing no moving objects in the scene). Efforts are being made to lift this restriction in future work.

Magnetic Movie from Semiconductor on Vimeo.

The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries . All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries . Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons . Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world.
