Dust off those old smartphones and turn 'em into a powerful computing cluster!
Repurposing Outdated Smartphones for Homemade Server Cluster
Across the globe, folks carry super-powered mini-computers in their pockets every day, oblivious to the scope of their present-day pocket rockets. Take the Zenfone Max Pro M1, for instance - a relic from yesteryears, harnessable with a bit of know-how, to run a clever Linux distro called postmarketOS. This ain't the stock Android we're familiar with, but a nearly full-fledged Linux environment! Accessible by simple SSH magic, it enables the phones to host self-managed services, salted with a dash of Kubernetes for good measure. Denys, an enterprising techie, flaunts his three-phone cluster, hosting a swath of self-hosted services.
Much like Denys, if you find yourself with a surplus of dusty smartphones or those bearing broken displays, you've hit jackpot! Repurpose these bad boys for some extra computing muscle, saving a few bucks in the process when compared to springing for a Raspberry Pi. Plus, in many cases, phones sport more kick than a typical Pi model, offering you a winning edge in terms of CPU/RAM performance.
So here's what you're gonna do: get yourself a phone with an unlockable bootloader - the Zenfone, Samsung Galaxy line, and others fit the bill nicely. Next, unlock that bootloader. For Zenfone enthusiasts, follow specific command-line instructions to unlock. Now, flash postmarketOS onto your device, using fastboot or Heimdall commands. Post that, configure your network and storage settings to prepare your cluster for action.
To set up the Kubernetes cluster, follow standard k3s procedures, designating one device as the master node and the others as workers. Finally, ensure proper configuration, and et voila! You've got yourself a small-scale, efficient computing cluster that'll put your idle Android devices to good use!
Trust my source, Denys, for he's gone to great lengths to share his guide on this DIY project. If you're keen on this, take a peek at the enrichment data for detailed, device-specific installation instructions. Happy hacking!

Repurposing Old Smartphones in a Nutshell
- Select Devices: The Asus Zenfone Max Pro M1, Samsung Galaxy series, and more can work great for this project.
- Unlock Bootloader: For Zenfone Max Pro M1, power up the phone, hold Volume Up and enter Fastboot mode to unlock. Deets on other brands can be found here.
- Install postmarketOS: PostmarketOS wiki houses device-specific installation instructions.
- Configure Network and Storage: Ensure devices are networked and optimize storage options for your cluster.
Bonus Tip: Kubernetes and Customized Cluster
- Install Kubernetes: Regular k3s (lightweight K8s distro) setup procedures apply here. Pick one device as the master node and the rest as workers.
- Cluster Configuration: Use k3s to manage and configure your cluster effectively.
