Researchers Build Data Center from 2,000 Pixel Phones
Researchers from the University of California, San Diego, together with Google Research, demonstrated a proof-of-concept small data center built from 2,000 retired Google Pixel smartphones. They removed the phones' motherboards, arranged them into clusters of 25–50 boards, and replaced Android with Linux to avoid Android features (e.g., the Low Memory Killer) that would interfere with sustained compute. Early tests showed that a modest cluster of phones could host cloud applications for a classroom of more than 75 students; Google estimates all 2,000 devices could support roughly 100 such classes. The team notes the approach is not suitable for large-scale AI workloads but could offer a low-cost, lower-carbon compute option for small organizations, educational institutions, or agencies seeking inexpensive server capacity while reducing electronic waste.
A technical research demonstration involving Google shows an alternative, low-cost compute approach using retired devices; relevant to infrastructure, sustainability and small-scale cloud deployments and may influence low-cost/edge compute strategies.

Key Takeaways & Evidence Grounding
- Researchers from the University of California, San Diego collaborated with Google Research on the project.
- Google provided 2,000 retired Pixel smartphones for the experiment.
- Researchers removed the phones' motherboards, grouped them into clusters of 25–50, and installed Linux in place of Android.
- In initial tests, a small smartphone cluster could run cloud applications for more than 75 students; Google projects 2,000 devices could support about 100 classes of 75 students each.
- The setup is presented as a low-cost, lower-carbon alternative for small-scale server needs but is not sufficient for large-scale AI or highly resource‑intensive workloads.

Old Pixel Phones Reused as Mini Compute Clusters
Researchers at the University of California, San Diego in collaboration with Google Research demonstrated how retired Google Pixel smartphones can be repurposed into a small, low‑cost computing cluster. Google provided 2,000 old Pixel devices; researchers removed the phone motherboards, grouped them into clusters of 25–50 boards, and replaced Android with Linux to avoid Android memory-management restrictions such as the Low Memory Killer. Initial tests showed small clusters can host cloud‑based applications for more than 75 students simultaneously; scaling all 2,000 devices could support roughly 100 classes of 75 students each. The university says the setup incurred only a fraction of the cost of comparable server solutions. The project is framed as a way to reduce electronic waste while providing affordable compute for education, small organizations, and public institutions.
Old Phones as Bodies: LLM Agents Coordinate via Shared Log
An engineer describes a self-hosted, open-source multi‑agent system built from a laptop, several old Android phones, a small VPS and a home router. Sensors (mic, camera, BLE, GPS, accelerometer) run on phones via Termux and are accessed over SSH; the agents are LLMs running in tmux panes on a Linux host. Tailscale provides the mesh network and a shared text stream (tmux scrollback) is the agents' coordination log where they post [task]/[taking]/[done] markers. Design principles include strict separation of sensing and reasoning, a verification principle that requires real artifacts/tests (e.g., JPEG/.m4a) rather than trust, and a single-writer substrate for critical edits with rollback. The project is open-source (github.com/genaforvena/lte-workstation, CC0) and presented as an experiment rather than a product. Published 2026-06-24.
Google Sends AI Chips to Space for Testing
Google's Project Suncatcher has launched its first AI chip into orbit, marking a step toward space-based data centers. The prototype satellite, built with Planet Labs and launched on SpaceX's Transporter-18 mission, carries four Trillium TPUs, the same chips used for Gemini models. Testing these chips against radiation, vibration, and extreme temperatures, the mission runs Google's Gemma model in 15-minute intervals due to heat dissipation challenges in a vacuum. The one-year mission aims to validate endurance; ground tests showed higher radiation resistance than expected, but silent data corruption remains a challenge. Economic viability requires launch costs below $200 per kilogram, needing about 1,800 Starship flights over ten years. Google published groundwork in Joule and plans two more satellites with laser links by early 2027, aligning with Elon Musk's vision of solar-powered orbital data centers.
