DIY Smart Glasses

Mount components on glasses.

1. Choose a sturdy safety glasses frame.
2. Plan component placement: display on one lens, camera on bridge, Pi on temple.
3. Use hot glue or small screws to mount components securely.
4. Ensure display is at a comfortable viewing angle.

Wire display to Pi via I2C.

1. Connect OLED VCC to Pi 3.3V.
2. Connect OLED GND to Pi GND.
3. Connect OLED SCL to Pi GPIO 3 (SCL).
4. Connect OLED SDA to Pi GPIO 2 (SDA).
5. Enable I2C: sudo raspi-config → Interface Options → I2C → Enable.

Verify OLED works.

1. Install required libraries: sudo apt-get install python3-pil python3-pip && sudo pip3 install adafruit-circuitpython-ssd1306
2. Run a test script to display text on the OLED.
3. Verify text is visible and clear.

Add camera for AR features.

1. Connect Pi Camera to the CSI port or USB camera to USB port.
2. Enable camera: sudo raspi-config → Interface Options → Camera → Enable.
3. Test: raspistill -o test.jpg

Display information on glasses.

1. Write Python script to show time, notifications, or camera feed on OLED.
2. Implement basic AR features like text overlay or object detection.
3. Optimize for low power consumption.

import board
import busio
from PIL import Image, ImageDraw, ImageFont
import adafruit_ssd1306
import time

i2c = busio.I2C(board.SCL, board.SDA)
display = adafruit_ssd1306.SSD1306_I2C(128, 64, i2c)

display.fill(0)
display.show()

image = Image.new('1', (display.width, display.height))
draw = ImageDraw.Draw(image)
font = ImageFont.load_default()

while True:
    draw.rectangle((0, 0, display.width, display.height), outline=0, fill=0)
    
    current_time = time.strftime("%H:%M:%S")
    draw.text((10, 10), current_time, font=font, fill=255)
    draw.text((10, 30), "Smart Glasses", font=font, fill=255)
    
    display.image(image)
    display.show()
    time.sleep(1)

Power with battery.

1. Connect a small LiPo battery or USB power bank to the Pi.
2. Secure battery to temple arm of glasses.
3. Test runtime (expect 2-4 hours depending on battery).
