E-Paper Image Frame

 
 

E-Paper Image Frame - Full-Stack Web Application

A sophisticated digital photo management system built for e-ink displays, demonstrating advanced web development and IoT integration skills.

This project showcases a complete full-stack solution combining modern web technologies with hardware integration. Built with FastAPI and featuring a responsive web interface, the application enables remote management of a digital photo frame powered by e-ink display technology.

Key Technical Achievements:

  • Advanced Image Processing: Implemented intelligent crop-to-fill algorithms with visual drag-and-drop crop editor that maintains aspect ratio constraints

  • Real-Time Web Interface: Developed a modern, mobile-responsive UI with live image preview and instant display updates

  • Database Architecture: Designed efficient SQLite schema with SQLAlchemy ORM for image metadata, crop coordinates, and usage analytics

  • Hardware Integration: Created seamless interface with Pimoroni Inky e-paper displays for low-power, always-on photo display

  • Performance Optimization: Built automatic thumbnail generation, image caching, and efficient file management systems

Technical Stack: Python, FastAPI, SQLAlchemy, JavaScript, HTML5/CSS3, PIL/Pillow, SQLite

Problem Solved: Traditional digital photo frames require physical interaction and often display images poorly due to aspect ratio mismatches. This solution provides remote management capabilities with intelligent image processing that ensures perfect display fitting through advanced cropping algorithms.

Business Value: Demonstrates full-stack development capabilities, IoT integration expertise, and user experience design skills applicable to smart home products, content management systems, and hardware-software integration projects.
