Where good ideas come from

People often credit their ideas to individual “Eureka!” moments. But Steven Johnson shows how history tells a different story. His fascinating tour takes us from the “liquid networks” of London’s coffee houses to Charles Darwin’s long, slow hunch to today’s high-velocity web.    

10 top time-saving tech tips

Tech columnist David Pogue shares 10 simple, clever tips for computer, web, smartphone and camera users. And yes, you may know a few of these already — but there’s probably at least one you don’t.    

A 12-year-old app developer

Most 12-year-olds love playing videogames — but Thomas Suarez taught himself how to create them. After developing iPhone apps like “Bustin Jeiber,” a whack-a-mole game, he is now using his skills to help other kids become developers.    

The new bionics that let us run, climb and dance

Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature’s own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab’s Biomechatronics group, he shows his incredible technology in a talk that’s both technical and deeply personal — with the help of ballroom dancer Adrianne Haslet-Davis, who lost her left leg in the 2013 Boston Marathon bombing, and performs again for the first time on the TED stage.    

A robot that flies like a bird

Plenty of robots can fly — but none can fly like a real bird. That is, until Markus Fischer and his team at Festo built SmartBird, a large, lightweight robot, modeled on a seagull, that flies by flapping its wings. A soaring demo fresh from TEDGlobal 2011.    

The astounding athletic power of quadcopters

In a robot lab at TEDGlobal, Raffaello D’Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D’Andrea show drones that play catch, balance and make decisions together — and watch out for an I-want-this-now demo of Kinect-controlled quads.    

Meet the SixthSense interaction

This demo — from Pattie Maes’ lab at MIT, spearheaded by Pranav Mistry — was the buzz of TED. It’s a wearable device with a projector that paves the way for profound interaction with our environment. Imagine “Minority Report” and then some.    

The thrilling potential of SixthSense technology

At TEDIndia, Pranav Mistry demos several tools that help the physical world interact with the world of data — including a deep look at his SixthSense device and a new, paradigm-shifting paper “laptop.” In an onstage Q&A, Mistry says he’ll open-source the software behind SixthSense, to open its possibilities to all.

DIY Universal Robot Gripper

There are a lot of different kinds of robot grippers (end effectors). The most common strategy when designing a robot hand is to try to replicate the human hand. However, in 2010 researchers at Cornell University and University of Chicago developed a unique approach. They created an amorphous gripper that was able to mold itself to the object that it wanted to pick up. This kind of gripper is much more versatile. In this project, I am going to show you how to make your own DIY universal gripper for your robots.   Background: How It Works   This gripper works…

What purpose does the small cylindrical module near the end of my laptop charger cable serve?

They are called ferrite beads/EMI filters/ferrite chokes and contain the semi-magnetic substance Ferrite made from iron oxide (rust) alloyed with other metals . Usually seen on power chords, laptop charging cables and other electronic devices such as  printers and medical equipment. Any conductive cable acts as an antenna – if the device produces radio frequency energy, this can be transmittedthrough the cable, which acts as an unintentional radiator. What do the beads do? They prevent the cable from sending/recieveing signals. It has the property of eliminating the broadcast signals. Essentially, it “chokes” the RFI (Radio Frequency Interfearence) transmission at that point on the cable —…
