Google Project Ara Design Will Use Electro-Permanent Magnets To Lock In Modules 62
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."

But neither the summary, nor the terrible overly "modern" designed marketing website, makes much attempt at explaining intent. It's like wave "we're replacing email" doesn't explain anything to anyone. "We're making modular phones" doesn't tell us, at the very least, what might actually be different, day-to-day for users.

The idea is to make phones as modular as (or even more so than) a home PC.

Modern magnetometers in phones are pretty robust. After calibration, the one in my phone works fine right next to a 500 MHz NMR (~12 T [for reference the earth's magnetic field is around 50 uT]). The magnetic locks won't be moving around much, so the field it sees from them will be pretty static.

Interesting, I didn't know they have such a wide dynamic range. I knew a small rare-earth magnet near my phone would max out the Hall sensor value, but never considered recalibrating it in that state.
It's a bit difficult to test too, since it seems to use dead reckoning (accelerometer) as a fallback for rotation.

Nowadays, a quadcore CPU + GPU with LCD controller + LTE/CDMA/HSPA/EDGE/GSM modem + a/b/g/n/ac-Wifi + Bluetooth + GPS/Glonass/Galileo + FM radio + camera controller + Dual-SIM and SD card interface is a 3-chip solution (e.g. MT9565 platform). Mind those chips plus RAM and Flash should be placed directly together, not via contacts to pluggable modules.

If it's not intended for the masses, then it's going to fail on all important points:

Your reasons for it to fail (as listed here) are still reasons that would make a device _INTENDED FOR THE MASSES_ fail. There are products that are intended for niche markets that still succeed, and this project will succeed or fail based on those criteria, not your strawman criteria.

Actually, that has been one of the major roadblocks. Figuring out a strong method of locking the modules in is a great step forward. I could be remembering incorrectly, but I believe they were going to make it so you would run an app on your phone to "unlock" the module(s) so you could remove/replace them, then "lock" them back when you were done.

Were it technologically possible it would be a hit, yes. Unfortunately you can't just jam CPUs and memory into a matrix of pin holes where ever and how ever you want.
