Predict Eclipses with Antikythera Mechanism Made from LEGOs

Antikythera Mechanism

Antikythera Mechanism

This is one of the most impressive LEGO projects I have seen in a while. It’s doesn’t take a lot of LEGOs to build, but the precision that is involved makes it the most impressive.


Here is the history: What was thought to be Greek technology turned out to Babylonian. Around the first century BC, a device – Greek in construction – was built to determine the 12 signs of the Zodiac. It had a bottom dial that was in a 223 month cycle – That of a standard eclipse.  The top dial was in a 235 month cycle, for distribution of new moons.

In 1901, this device was salvaged after a ship crashed on the Antikythera island. That is why it’s called the Antikythera Mechanism.

Scientists have since reconstructed this machine, only from clues the damaged device . What was lost for 2000 years has now been found…

… and made out of LEGO.

When I saw this video, I had to stop in . It’s an amazing feat for anyone. But nowadays, we have the ability to create something as complex as this out of something meant for kids at one time.

So sit back and watch how this device was created. If you want more info on the Antikythera Mechanism, check out this article on
