**Networked Smart Mirror with PyQt6 and OpenCV** A smart mirror is an interactive mirror that displays information such as the weather, calendar events, and news. In this example, we will create a networked smart mirror using PyQt6 and OpenCV. **Installation and Setup** To start, you will need to install the required libraries. You can do this by running the following command in your terminal: ```bash pip install pyqt6 opencv-python ``` **Core GUI Components** The smart mirror will have the following core GUI components: * A QLabel to display the current weather * A QLabel to display the current calendar events * A QLabel to display the current news * A QPushButton to exit the application Here is the code to create these components: ```python import sys from PyQt6.QtWidgets import QApplication, QWidget, QLabel, QPushButton, QVBoxLayout from PyQt6.QtGui import QFont from PyQt6.QtCore import Qt class SmartMirror(QWidget): def __init__(self): super().__init__() self.weather_label = QLabel("Weather: ") self.calendar_label = QLabel("Calendar Events: ") self.news_label = QLabel("News: ") self.exit_button = QPushButton("Exit") layout = QVBoxLayout() layout.addWidget(self.weather_label) layout.addWidget(self.calendar_label) layout.addWidget(self.news_label) layout.addWidget(self.exit_button) self.setLayout(layout) self.exit_button.clicked.connect(self.close) if __name__ == "__main__": app = QApplication(sys.argv) smart_mirror = SmartMirror() smart_mirror.show() sys.exit(app.exec()) ``` **Networking and API Integration** To get the current weather, calendar events, and news, we will use APIs. We will use the OpenWeatherMap API for the weather, the Google Calendar API for the calendar events, and the NewsAPI for the news. Here is the code to get the current weather: ```python import requests class SmartMirror(QWidget): def __init__(self): super().__init__() # ... self.weather_api_key = "YOUR_OPENWEATHERMAP_API_KEY" self.weather_url = f"http://api.openweathermap.org/data/2.5/weather?q=London&appid={self.weather_api_key}" self.get_weather() def get_weather(self): response = requests.get(self.weather_url) weather_data = response.json() weather_description = weather_data["weather"][0]["description"] temperature = weather_data["main"]["temp"] self.weather_label.setText(f"Weather: {weather_description}, Temperature: {temperature}K") if __name__ == "__main__": app = QApplication(sys.argv) smart_mirror = SmartMirror() smart_mirror.show() sys.exit(app.exec()) ``` Here is the code to get the current calendar events: ```python import datetime import google.auth from googleapiclient.discovery import build class SmartMirror(QWidget): def __init__(self): super().__init__() # ... self.calendar_api_key = "YOUR_GOOGLE_CALENDAR_API_KEY" self.calendar_url = f"https://www.googleapis.com/calendar/v3/calendars/primary/events?key={self.calendar_api_key}" self.get_calendar_events() def get_calendar_events(self): service = build("calendar", "v3", developerKey=self.calendar_api_key) now = datetime.datetime.utcnow().isoformat() + "Z" events_result = service.events().list(calendarId="primary", timeMin=now, singleEvents=True, orderBy="startTime").execute() events = events_result.get("items", []) event_text = "" for event in events: event_text += f"{event['summary']}: {event['start']['dateTime']} - {event['end']['dateTime']}\n" self.calendar_label.setText(f"Calendar Events:\n{event_text}") if __name__ == "__main__": app = QApplication(sys.argv) smart_mirror = SmartMirror() smart_mirror.show() sys.exit(app.exec()) ``` Here is the code to get the current news: ```python import requests class SmartMirror(QWidget): def __init__(self): super().__init__() # ... self.news_api_key = "YOUR_NEWSAPI_API_KEY" self.news_url = f"https://newsapi.org/v2/top-headlines?country=us&apiKey={self.news_api_key}" self.get_news() def get_news(self): response = requests.get(self.news_url) news_data = response.json() news_text = "" for article in news_data["articles"]: news_text += f"{article['title']}: {article['description']}\n" self.news_label.setText(f"News:\n{news_text}") if __name__ == "__main__": app = QApplication(sys.argv) smart_mirror = SmartMirror() smart_mirror.show() sys.exit(app.exec()) ``` **OpenCV Integration** To display the smart mirror's UI on top of a video feed, we will use OpenCV. Here is the code to display the UI on top of a video feed: ```python import cv2 class SmartMirror(QWidget): def __init__(self): super().__init__() # ... self.video_capture = cv2.VideoCapture(0) self.update_timer = QTimer() self.update_timer.timeout.connect(self.update_video_feed) self.update_timer.start(1000 // 30) def update_video_feed(self): ret, frame = self.video_capture.read() cv2.imshow("Smart Mirror", frame) if cv2.waitKey(1) & 0xFF == ord("q"): self.close() if __name__ == "__main__": app = QApplication(sys.argv) smart_mirror = SmartMirror() smart_mirror.show() sys.exit(app.exec()) ``` That's it! This is a basic implementation of a networked smart mirror using PyQt6 and OpenCV. You can customize it to display more information or to use different APIs. **Conclusion** In this example, we created a networked smart mirror using PyQt6 and OpenCV. We used APIs to get the current weather, calendar events, and news, and displayed them on top of a video feed using OpenCV. This is just a basic implementation, and you can customize it to display more information or to use different APIs. **External Links** * [PyQt6 Documentation](https://www.riverbankcomputing.com/software/pyqt/) * [OpenCV Documentation](https://docs.opencv.org/) * [OpenWeatherMap API Documentation](https://openweathermap.org/api) * [Google Calendar API Documentation](https://developers.google.com/calendar/api) * [NewsAPI Documentation](https://newsapi.org/docs) **Leave a comment** Please leave a comment below if you have any questions or need further clarification on any part of this example.
