While this is ostensibly a video meet-and-greet with some of the folks working for the cause, there are still some tantalizing parts to gaze upon. We're given a quick look at how component modules like processors and cameras are held in place by electropermanent magnets -- they slide into place easily, and are locked and unlocked with a quick burst of voltage that'll ultimately be controlled with an app. For a few brief moments, we also get a look at the three different endoskeletons that those parts pop into side by side... if only in render form. The mainstream medium model is the one that's been getting all the attention lately, but the phablet-sized endo looks like it'll support 9 modules on its rear and the mini model that could sell for about $50 can handle at least 6. Not enough Ara meat for you? Never fear: the first Ara Developer Conference will take place on April 15, so expect most of the project's secrets to be spilled very shortly.
