How to Build a Raspberry Pi-Powered Smart Mirror

Building a Raspberry Pi-powered smart mirror is an engaging project that combines hardware assembly with software configuration. Here’s a step-by-step guide to help you create your own smart mirror:

Materials Needed:

• Raspberry Pi: A Raspberry Pi 3 or newer model.
• Monitor: A monitor with HDMI input; the size depends on your preference.
• Two-Way Mirror Acrylic: This allows the display to show through while reflecting like a mirror.
• Frame: A frame to house the monitor and Raspberry Pi.
• Power Supply: Appropriate power adapters for the Raspberry Pi and monitor.
• Cables: HDMI and power cables.
• Keyboard and Mouse: For initial setup.

Instructions:

1. Prepare the Monitor:
   • Remove the monitor’s casing to access the internal components.
   • Ensure the display panel is clean and free from any obstruction
2. Install the Two-Way Mirror:
   • Cut the two-way mirror acrylic to fit the monitor’s dimensions.
   • Attach the mirror to the front of the monitor using adhesive strips or double-sided tape.
3. Assemble the Frame:
   • Construct a frame that can securely hold the monitor and Raspberry Pi.
   • Ensure there are openings for ventilation and cable management.
4. Set Up the Raspberry Pi:
   • Install the Raspberry Pi OS on a microSD card.
   • Connect the Raspberry Pi to the monitor via HDMI.
   • Power on the Raspberry Pi and complete the initial setup.
5. Install Smart Mirror Software:
   • Open a terminal on the Raspberry Pi.
   • Install the MagicMirror² software by running the following commands:

     cd ~
     git clone https://github.com/MichMich/MagicMirror
     cd MagicMirror
     npm install
     

   • Start the MagicMirror application to test the setup:

     npm start
     

   • Configure the modules and settings by editing the config/config.js file.
6. Finalize Assembly:
   • Mount the Raspberry Pi securely within the frame.
   • Route and conceal all cables to maintain a clean appearance.
   • Place the assembled smart mirror in your desired location.
