Project Ara was delayed in part due to electropermanent magnets not holding together well (Updated)
Update: Project Ara has just tweeted that the strength of the magnetic forces holding together the Ara phone modules is not, in fact, a problem — apparently that was a joke. We’ve since heard that the strength of the magnetic fields produced by the magnets being used is approximately 30 Newton-meters, more than enough strength to hold a 30 gram electronic module in place. The comments about building a better attachment/detachment solution still seem to be true, however, with the tweet also saying that, “We have been configuring a new solution. It’s better too.” The team is also working on improved camera and battery modules.
Google’s Project Ara, the name of the modular smartphone system the company is building that would enable anyone to put together a phone on their own, has run into problems that have impacted its public test roll-out. The team behind it has been cheeky and somewhat coy in explaining why it has delayed a test launch of the unique system, but a concise message posted to Twitter today might at least partly explain the delay.
