CHAPTER 01 — THE PROBLEM

Billions of still-powerful processors are thrown away every year

A five-year-old phone can still run a Linux server. But a swollen battery and expired software get the whole device discarded, along with parts that are perfectly good.

5.3 billion

phones discarded in 2022 alone

92% RESIDUAL COMPUTE VALUE

Intact CPU, RAM and high-speed Flash silicon

Empirical ARM64 8-core silicon qualification

HARDWARE HAZARDS PURGED

Aging Lithium-ion battery (Swelling and fire hazard when left on 24/7)
OLED/LCD display & digitizer (Draws 4-8W of useless idle power)
Bloatware-heavy OEM Android runtime & analytics trackers

SILICON BLOCKS REBORN

High-clock 64-bit 8-Core ARM64 SoC with compute acceleration
UFS 2.1/3.1 flash storage reading up to 850 - 1800 MB/s
Low-latency LPDDR4X system RAM with extreme memory bandwidth
Dual-Band AC/AX Wi-Fi & autonomous recovery SoftAP bridge

CHAPTER 02 — REBIRTH

Keep what is good, remove what is harmful

We drop the screen, the battery and the bloatware, and keep the four blocks that make the chip powerful.

SILICON REBIRTH PIPELINE

AUTO-ADVANCING

STAGE 01 / 05

Silicon Salvage

Screening high-performance 8-core ARM64 processors with intact compute power.

01 / SOC

8-Core Big.LITTLE ARM64 SoC

Intelligent task scheduling: High-performance Cortex-A7x cores handle heavy container workloads, while power-sipping Cortex-A5x cores run background daemons 24/7.

02 / FLASH

High-Speed UFS & eMMC Flash

Sequential read speeds of 850 - 1800 MB/s. Solid-state industrial endurance completely eliminates filesystem corruption common with microSD cards.

03 / RAM

High-Bandwidth LPDDR Memory

Up to 3x higher memory bandwidth and lower latency than typical SBCs, ensuring dozens of concurrent containers run smoothly without bottlenecks.

04 / NET

Dual-Band Wi-Fi & Fallback SoftAP

Dual-Band AC/AX wireless paired with autonomous fallback hotspot broadcasting for instant local recovery during network outages without container reboots.

VOLTAGE RAIL DC 9V–24V ≥ 2A Barrel Jack 5.5x2.1mm

COOLING PROTOCOL Dual-Zone CNC Fin + Smart PWM Fan (≤ 18 dB)

SUPERVISOR PLATFORM Debian / Ubuntu Minimal Rootless

FACTORY QUALIFICATION 48 Hours 100% Burn-in Multi-Core Stress

CHAPTER 03 — POWER & THERMAL

One power cable, no battery, running 24/7

Direct DC 9V–24V through a 5.5x2.1mm barrel jack removes all battery swelling risks. Dual-zone CNC heatsinks paired with smart PWM mini fan keep core temperatures at 38–48°C under continuous 24/7 load in whisper-quiet acoustics (≤ 18 dB).

24/7 POWER CONSUMPTION

24/7 Silicon Power Efficiency

Direct DC 9V–24V power eliminates AC-DC conversion inefficiency and battery swelling hazard, delivering an industry-leading performance-per-watt ratio.

CHAPTER 04 — SOVEREIGNTY

Your data stays inside your home

A PreCores server reports to no central hub. Every backup and credential stays on your local network.

HARDENED PRIVACY

Zero Cloud Telemetry

No telemetry, vitals, or metrics are ever sent to central servers. Completely air-gapped from cloud tracking.

100% OFFLINE

Air-Gapped Offline Backup

Encrypted .pcl-bak backup files are downloaded directly in-browser or written to local USB OTG without cloud hops.

SECURE ISOLATION

Rootless Namespace Isolation

All microservices run in isolated rootless Linux namespaces. Container root maps to host UID 100000+.

LOCAL CRYPTO

On-Device Cryptography

Argon2id KDF and CSPRNG session tokens are generated purely on-device. No shared universal master keys.

CHAPTER 05 — ECOSYSTEM

Install apps with a single click

The self-hosted service catalog is synced live from the PreCores registry, so it always matches what your appliance can install.
