not-completely-original, but still-pretty-neat idea: littleBits. Tiny, pre-assembled circuit boards that create a library of mix-and-match electronic components for building that next amazing wonder widget. Oh, and they're open source. The "blocks" snap together via magnets, and there's an ever-growing selection of modules to choose from. The project is still in its infancy, but we're expecting to see some good work from Joe Hacker Guy on the DIY scene, or anybody else too afraid to pick up a soldering iron, once these arrive at some sort of retail availability. An intro video is after the break.
