3D scanners are kinda old hat at this point. But, while we've seen more than our fair share of Kinect hacks, we haven't come across too many phone-based systems. Moedls actually puts the power to create models like the one above in the palm of your hand... sort of. The heart of the system is either an iOS or Android app (sorry MeeGo fans), but there are actual lasers with a custom enclosure as part of the platform. Clearly, that does somewhat restrict portability, but it should all fit into a 10-inch x 10-inch x 4-inch box for storage or transportation.
Creator John Fehr started the project as a way to save some of his daughter's sculptures in digital form. After trying many different component options, Fehr settled on a combination of parts that totaled around $300. That included a custom enclosure and variable speed rotating platform have been sourced. Right now the iOS app is awaiting approval from Apple and the Google-fied equivalent is currently in development. Combine this with a 3D printer (we hear you've got quite a few choices at this point) and the world becomes your playground. You can see an example of what Moedls is capable of, even at this early stage, at the source.
