Builders, inventors and hardware hackers let their geek flags fly at World Maker Faire in New York City and E4C had a look at the innovations. We combed through the homespun designs to find the machines that have the potential to improve lives and boost economic development worldwide.

A little more about MakerFaire: It has become one of the best-known showcases for crafters and tech enthusiasts in the United States, with inventors hailing from around the country and around the world. These are a few of the projects that caught our attention.
