How a School Student Built a Smartphone from Old Mobiles and a 3D Printer
1. The Idea: Why Build a DIY Smartphone?
Smartphones today are expensive, and millions of people discard old phones every year, leading to an increase in electronic waste (e-waste). The young innovator wanted to reduce e-waste while learning about hardware engineering and software development.
- Sustainability Focus: Instead of throwing away old mobile phones, why not reuse the functional parts?
- DIY Learning: The student was passionate about learning how smartphones work from the inside out.
- Affordability: Flagship phones cost $800-$1,500, but this DIY smartphone was built for under $100.
2. Materials Used to Build the Phone
The project involved recycling old smartphone parts and using a 3D printer to create a custom smartphone case. Here’s what was needed:
- Old smartphones for display, camera, battery, and other components
- A Raspberry Pi Zero W or similar microcontroller for the phone’s processing power
- A 3D printer to create a custom case and body
- Open-source operating system to run the smartphone
- Basic electronic components like resistors, capacitors, and wires
3. Step-by-Step Guide to Building a Smartphone
For those inspired by this innovation, here’s a simple guide to building a DIY smartphone:
Step 1: Gather Old Smartphone Components
Find old smartphones that are no longer in use. The student salvaged parts from old devices, including:
- Screen (LCD/OLED)
- Camera module
- Battery
- Microphone & Speaker
- Motherboard and small chips
Step 2: Design the Phone’s Frame Using a 3D Printer
- The student used a 3D modeling software (like Blender or Tinkercad) to design a custom phone body.
- The 3D printer created a sturdy but lightweight phone casing.
- The printed casing had slots for the screen, buttons, and charging ports.
Step 3: Assemble the Hardware Components
- The salvaged parts were carefully reconnected using electronic circuits.
- A Raspberry Pi Zero W was used as the main processing unit.
- The battery was connected and optimized for power efficiency.
- A custom circuit board helped connect all components securely.
Step 4: Install an Open-Source Operating System
- The student installed PostmarketOS, a Linux-based system for mobile devices.
- Open-source software allowed the DIY phone to perform basic functions like calling, texting, and browsing the internet.
- Custom applications were added for extra functionality.
Step 5: Testing and Optimization
- The phone was tested for battery life, display clarity, and call quality.
- The software was optimized to run smoothly on the custom hardware.
- A few extra features, like wireless charging and voice recognition, were later added.
