Smart Mirror with Raspberry Pi: Complete FYP Build Guide

Why a Smart Mirror Stands Out as an FYP

Most FYP demos involve a breadboard and a laptop screen. A smart mirror is different — it's a finished, physical product that looks genuinely polished when it's done, which makes a strong first impression on a viva panel before you've said a word.

Under the hood, it's also a legitimate software and hardware integration project: Raspberry Pi running a display framework, pulling live data from APIs, and rendering it through a two-way mirror. That combination of embedded systems, front-end development, and API integration covers a lot of ground for one project.

Hardware Components

Component	Purpose	Cost (RM)
Raspberry Pi 4 (2GB+)	Runs the mirror software	RM 180–250
Monitor/LCD Panel (used)	Display	RM 100–200
Two-Way Acrylic Mirror	Reflective front panel	RM 60–100
Wooden Frame	Housing	RM 50–100
PIR Motion Sensor	Wake on approach	RM 4–6
MicroSD Card (32GB)	OS storage	RM 15–20

Total hardware cost: RM 400–650 (varies significantly with monitor size and frame material)

Many students save on cost by reusing an old monitor and building the frame themselves — this is common and doesn't hurt your marks, since the assembly work itself is part of the technical contribution.

How It Works

Raspberry Pi runs MagicMirror² (an open-source modular smart mirror platform built on Electron/Node.js) or a custom-built dashboard
The display shows time, date, weather (via a weather API), and calendar events against a black background
A two-way acrylic mirror sits in front of the screen — where the display is black, it reflects like a normal mirror; where content is shown, it's visible through the glass
A PIR sensor detects when someone approaches and wakes the display, saving power/screen life when no one's around
Optional modules add news headlines, to-do lists, or Telegram notifications

Assembly Steps

Step 1: Prepare the Display

Strip the monitor's bezel if possible to reduce the frame's depth. Test that the screen still works before mounting anything permanently.

Step 2: Mount the Two-Way Mirror

Cut the acrylic mirror to the monitor's dimensions (or slightly larger to fit the frame). Clean both sides thoroughly — dust between the mirror and screen will be very visible once assembled.

Step 3: Build the Frame

A simple wooden box frame works well. Leave enough depth behind the mirror for the monitor and Raspberry Pi, plus airflow — these setups can run warm if enclosed too tightly.

Step 4: Install MagicMirror² on Raspberry Pi

bash -c "$(curl -sL https://raw.githubusercontent.com/MagicMirrorOrg/MagicMirror/master/installers/raspberry.sh)"

Configure config/config.js with your location for weather, and add modules for calendar, news, or notifications.

Step 5: Wire the PIR Sensor

VCC → 5V
GND → GND
OUT → GPIO 17

# Simplified wake/sleep logic
if pir_sensor.motion_detected():
    turn_on_display()
    reset_idle_timer()
elif idle_timer_exceeds(300):  # 5 minutes
    turn_off_display()

Presentation Tips

Bring the finished mirror to your viva if possible — the physical build carries a lot of the "wow factor" that's hard to replicate on a projector
Be ready to explain the two-way mirror principle (partial reflection vs. transmission) — it's a common examiner question and shows you understand the physics, not just the assembly
Highlight any custom module you built yourself (rather than using only pre-built MagicMirror modules) as your main technical contribution

Scope Recommendations

For a Diploma FYP: Time, date, weather display in a basic frame For a Degree FYP: Add PIR wake/sleep, calendar integration, and a custom-built module For Merit/Distinction: Add voice control, Telegram notifications, and a mobile app to remotely configure the display
