Google Project Tango: disassembling the "spatial tablet" from iFixit (4 out of 10 on the repair scale)

On Habré, several times they mentioned the new Google Project Tango tablet, which is able to rebuild the 3D model of the room in which the tablet is located. This device is not yet widely available, and every second user is unlikely to be interested in them, the device’s features are too specific.

Nevertheless, the device can be in demand among architects, graphic designers, civil engineers and representatives of a large number of other specialties. The other day, the iFixit service team disassembled the tablet, and assessed its maintainability.
