The Great Ball Contraption
Build a machine out of Lego that takes Lego soccer balls from an input hopper to an output hopper at a minimum rate of one per second by any means you can devise. Define a standard interface for this kind of machine so that the output of one will reliably feed the input of the next. Now invite hundreds of Lego fanatics to use their imagination to build modules of all different sizes and types to meet this standard – then connect them all end to end to make the biggest Rube Goldberg contraption in history. Thanks Steve! Link.

Longtailer Chris Anderson posts up about using some tools to create a rocket launcher from your favorite video game. 1. Capture a scene from your favorite videogame (HijackGL). 2. Import it into a CAD program and isolate an object you’d like to have. 3. Send it to a fabricator, either a 3D printer or a computer-controlled milling machine, and watch it emerge as a physical object. We’re still a few years away from doing this easily- but home fabricating isn’t that far away at all…
History of the video game controller- How did the current home-console controllers come to be? How have they evolved? You may have noticed some similarities between the current generation controllers, or between them and the previous generations of controllers. So, how do they all tie together? [
