Project Overview
Constructed a fully functional, high-performance desktop workstation using scavenged motherboards, power supplies, and RAM from 5 broken e-waste laptops.
Problem Statement & Engineering Motivation
Discarded electronic waste creates unnecessary environmental damage while containing perfectly operational silicon components.
Technical Architecture & Implementation
Diagnosed circuit faults across 5 salvaged laptops, extracted working motherboards and power controllers, built custom copper heatsink mounts, and wired a unified power supply and display output.
Key Technical Features
- Unified power delivery for salvaged mobile motherboard architecture
- Overclocked passive-to-active cooling loop for sustained workloads
- Stable Windows 11 installation capable of software development tasks
Technology & Component Stack
- Hardware Diagnostics
- Soldering & Wiring
- Custom Heatsinks
- Windows OS
- Power Distribution
Outcomes & Engineering Lessons Learned
- Laptop motherboards have stringent power handshake requirements that need dummy signals when external power supplies are used.
- E-waste recycling teaches hands-on electrical troubleshooting better than purely theoretical textbooks.
