Google Project Ara Design Will Use Electro-Permanent Magnets To Lock In Modules
MojoKid writes: "Google's Project Ara, an effort to develop a modular smartphone platform, sounded at first as much like vaporware, but Google is actually making it happen. In an upbeat video, Dave Hakkens (the guy who created the Phonebloks design that appears to be the conceptual basis for Project Ara) visited the Google campus to see what progress is being made on the project. The teams working on Project Ara have figured out a key solution to one of the first problems they encountered, which was how to keep all the modules stuck together. They decided to use electro-permanent magnets. In terms of design, they've decided not to cover up the modules, instead making their very modularity part of the aesthetic appeal. 3D Systems is involved on campus, as they're delivering the 3D printing technology to make covers for the modules."
.... the grunge that is going to collect between the modules!
It's really about the stupidest idea I've seen from Google.
Every pluggable/removable part multiplies the opportunity for failure. It's why so many consumer devices now have embedded non-user-removable batteries. (No, *not* to rip-off consumers when they have to pay for service to have the battery replaced. Most of these devices are discarded or removed from service before the battery might need replacement.)
