> Prior to deployment, smartphones must be processed to remove all but the motherboard

I wonder how long this takes per phone. Presumably it could be a pretty fast shucking process if you don't care about any of the other components. I can't see it making much economic sense if it takes more than 1 minute/phone.

Maps Camp Google 2007 -- to the assembled 400+ engineers and guests, at the podium. A calm and thoughtful pitch during the five minute talks "You at Google have a special responsibility, we all do, to make a closed loop industrial ecology with this hardware".. Later that month, bills unpaid, rent payments on credit, the blog EWasteInsights folds after two years.. Silicon Valley Bank has a another boozy party...

This is neat. This group’s approach of treating the devices as many weaker servers (basically a raspberry pi cluster) sounds like the most realistic way to reuse phone hardware at scale, especially with the backing of the actual hardware vendor.

It’s a genuine shame how locked down iPhones are compared to even Android. Hypothetically you could run Linux inside UTM[0] but outside the EU Apple makes it intentionally difficult, and there’s still memory restrictions and performance penalties.

My group’s senior year project was a computing cluster on phones (specifically targetting LLM inference) [1]. Instead of installing a new OS we built separate apps per OS. Our devices were older, so the Android phones had worse hardware and the iPhones had more software restraints.

I'm delighted to see at least someone is trying this. There are also millions of old laptops discarded every year, often with perfectly capable motherboards, but with minor issues outside of the compute (keyboards, screens, dead battery) which are just not economical to repair. Surely with the right software you can turn 10x 8GB i5 motherboards into something more than the sum of it's parts?

This is ignoring the fact that the main reason retired phones are e-waste is proprietary firmware blobs and locked-down systems preventing users from maintaining their phone with security updates, and very limited support length from OEM's leads to VERY insecure devices after they drop out of support. You should not be connecting these old devices to an internet accessible network. Google notably does well here with…

> This is ignoring the fact that the main reason retired phones are e-waste is proprietary firmware blobs and locked-down systems Couldn't Google somehow fix this? Since they control the substrate (Android) and they would be doing it for their convenience

They're literally doing the opposite, right now you can't install a custom operating system, but in the near future you won't be able to install custom apps either: https://keepandroidopen.org/

Earlier quoted context omitted.

Unfortunately it is a bit more complicated than that. All these phones run firmware, bootloaders, libraries under license from SoC providers, who package components from other vendors under a license themselves. Opening up the bootloader can be done, but two things have to happen: either the phone is crippled of various functionalities or the manufacturer is in breach of license because all the binary blobs become op…

I haven't ever heard of an SoC supplier demanding that the device's bootloader must be locked. Are you sure that this is happening? I've only ever seen devices delete first-party blobs, presumably of the manufacturer's own volition.

Unisoc mandates locked bootloaders, but it's true, the majority doesn't care, they just want to sell the SOC

Very weird that this is coming from Google, given that they made their phone platform specifically to not let you install your own operating system. And now, they're making it illegal to install custom apps too: https://keepandroidopen.org/

???

You can still install alternate OSes (eg. grapheneos) on their latest phones.

>And now, they're making it illegal to install custom apps too: https://keepandroidopen.org/

Besides the questionable use of "illegal" (what are they going to do, send you to jail?), that's not even accurate. You can still install apps after a 24 hour wait, or no wait at all if you use adb.

Really interesting project. Do you have a link to a writeup/paper?

You say that as if Google is a single hive mind with every team and vertical perfectly aligned like the Borg.

The article is pretty clear in the opening lines that this is a Google Research grant to the University of California, not even primarily done by Google employees.
