A collection of practical Python applications built with Tkinter GUI and computer vision capabilities. Each project is designed to be simple, functional, and educational.

A desktop application that translates text between multiple languages using a clean GUI interface.

Features:

• Translate between English, German, French, and Spanish
• Simple and intuitive user interface
• Real-time translation using the translate library

Tech Stack: Python, Tkinter, translate library

A real-time currency converter that uses live forex exchange rates to convert between different currencies.

Features:

• Support for major currencies (USD, EUR, GBP, JPY, CHF, TRY)
• Custom ISO code input for any currency
• Real-time exchange rates from forex-python
• Error handling with user-friendly messages

Tech Stack: Python, Tkinter, forex-python

A desktop countdown timer application with a graphical interface for setting time intervals.

Features:

• Set hours, minutes, and seconds using sliders
• Visual countdown display
• Start, stop, and reset functionality
• Alert notification when timer completes

Tech Stack: Python, Tkinter

A computer vision application that detects objects in real-time video streams using OpenCV and pre-trained models.

Features:

• Real-time object detection from video files or webcam
• Uses SSD MobileNet V3 model for fast processing
• CPU-based processing (no GPU required)
• Support for COCO dataset classes
• Bounding box visualization with confidence scores

Tech Stack: Python, OpenCV, NumPy

Each project has its own requirements.txt file with specific dependencies. See individual project directories for detailed requirements.

General Requirements:

• Python 3.10.4 or higher
• Tkinter (usually comes with Python)
• Internet connection (for language translator and currency converter)

# Clone the repository
git clone <repository-url>
cd py-projects

# Install dependencies for each project
cd language-translator && pip install -r requirements.txt
cd ../currency-converter && pip install -r requirements.txt
cd ../countdown-timer && pip install -r requirements.txt
cd ../realtime-object-detection && pip install -r requirements.txt

Navigate to any project directory and install its dependencies:

cd <project-name>
pip install -r requirements.txt
python main.py

Each project can be run independently:

# Language Translator
cd language-translator
python main.py

# Currency Converter
cd currency-converter
python main.py

# Countdown Timer
cd countdown-timer
python main.py

# Realtime Object Detection
cd realtime-object-detection
python main.py
