The Antikythera Mechanism in Lego (2m:57s)
Constructed between 100 and 150 BC, the Antikythera mechanism is one of the world's oldest known computers. Designed to calculate astronomical events, its purpose remained a mystery for decades following its discovery in a shipwrek off of the Greek island of Antikythera in the early 1900s. In the above video (The Antikythera Mechanism in Lego), from Small Mammal on Vimeo, John Pavlus follows the construction of a working replica made from Lego.

K'nex Mechanical Adding Machine (3m:10s)
Occasionally I worry that the integrated circuit will be the undoing of childhood tinkering. Just look at how hard it is to work on your own car these days. "Infernal computers!" Then I see something like this, and I'm immediately reminded why childhood is sooo cool. It's an excellent mechanical, macroscopic, and home-made example of what our computers do everyday. Score one for the tinkerers, and well done kwilliam2.
This DIY adder is only one product of a thoroughly charming community, building mechanical analogs of what are now mostly digital devices. Here's a cool Lego adder.

If you have spent any time browsing this video collection you know that I have a fondness for linking to wikipedia. What is wikipedia you ask? If you don't know, please click on the clip, and let the founder explain.

MARS Dead or Alive (46m:07s)
This video follows the creation and use of NASA's semi-autonomous Mars rovers--Spirit and Opportunity. I remember watching this hours after Spirit's January 3, 2004 landing on MARS. It was wonderfully exciting, watching the project's history then immediately seeing the first images back from the surface. Every NASA mission should be shadowed by such a talented film crew.
This episode is one of two. The second, Welcome to Mars, can also be found on Hulu.

In addition to collecting other people's videos, I produce my own intermittent video series. It presents answers to science questions, demos, experiments and the like.
