Google For Makers

Among the friends we've been making over in the PopSci booth at Maker Faire include the guys from Octoparts—an aggregate search engine for electronic components. If you've ever tried to buy resistors, capacitors, or any other component on the Web, you know how obscure and confusing some of these ordering sites can be—if you don't know your part number, you're often out of luck. With Octoparts, just type in what you're looking for and find the best price. In the works is an online app to save and share your parts list for your project. Now that Radio Shack has  almost entirely moved out of the components trade in their stores, Octoparts is a new tinkerer's dream. —John Mahoney
