Lego Antikythera Mechanism
Videos for Engineers

RF Cafe Video For Engineers - Lego Antikythera Mechanism LEGO® and tinkerers of all ages have enjoy a long, synergistic relationship that has led to incredible creations of mechanical contraptions and artistic sculptures. I have reported previously on LEGO re-creations of the Babbage Difference Engine, a fully-functional Fender guitar, and even full-size human replicas (do a search on LEGO images). Now, an Apple engineer has re-created the long-lost and recently-found Greek Antikythera Mechanism. 1,500 LEGO blocks and 110 gears were combined over a 30-day period of designing, building, and testing to produce this mechanical wonder. Maybe Apple should assign this guy to design the iPod 5 antenna - or at least the long-awaited iPod 4 white case!

Some Antikythera Mechanism History:

The Antikythera Mechanism is a geared, mechanical calculator that was built by the Greeks around the end of the second century BC. It is named after its place of discovery in 1901 in a Roman shipwreck off RF Cafe - Original Greek Antikythera Mechanismthe Antikythera islands. The mechanism is technically more complex than any known device for at least a millennium afterwards. Its functionality remained a mystery for nearly a century because of the encrusting by barnacles. Finally, in 2005, high-resolution X-ray tomography of the surviving fragments enabled researchers to reconstruct the gear function and decipher many of the surface inscriptions, which assisted in determining the device's functions. The mechanism predicted lunar and solar eclipses as well as orbital motions of all the known planets of the day (through Jupiter) and the Earth's moon. The front dial is marked with the divisions of the Egyptian calendar. Inside this there is a second dial marked with the Greek signs of the Zodiac. This second dial is moveable dial so that it can be adjusted to compensate for leap years.
