E-Paper Currency Tracker

Python-based project displays real-time currency exchange rates on an e-paper screen, housed in a custom-crafted wooden box.

Overview

Welcome to my e-Paper Currency Tracker Project! This project is designed to fetch and display currency exchange rates on an e-paper display. It's built using Python and integrates various technologies to create a seamless and efficient user experience. The project is perfect for anyone interested in hardware interfacing, web development, or financial data visualization. In addtion, I created a self-creafted wooden box to fit the e-paper as well as the Raspberry Pi Zero to make it a great addition to a desk.

Features

• Currency Exchange Rate Display: Fetches and displays the latest exchange rates on the e-paper.
• Trend Analysis: Analyzes and displays the trend of exchange rates over a specified period.
• Customizable Settings: Allows users to select target currencies through a locally hosted web interface.
• Elegant Wooden Enclosure: A custom-crafted wooden box houses the e-paper display, adding a professional and aesthetic touch to the technology.

Technologies Used

• Python: The core language used for scripting the project.
• Flask: A micro web framework used for handling web server operations.
• Redis: Utilized for caching exchange rate data to reduce API calls.
• Pillow & Matplotlib: Libraries used for image processing and graph plotting respectively.

Hardware Requirements

This project is designed for an e-paper display with specific attributes. To run this project, ensure your setup meets the following requirements:

• Waveshare 2.9inch e-Paper Module
• Microcontroller such as an Arduino or Raspberry Pi

Installation (For Compatible Setups)

If you have the necessary hardware, you can install and run this project as follows:

1. Clone the repository:

   git clone https://github.com/Vincent881909/e-paper.git

2. Install the required packages:

   pip install -r requirements.txt

Running the Project (For Compatible Setups)

To run the project on your compatible e-paper display:

1. Start the Redis server on your local machine.
2. Run the Flask web server:

   python web/app.py

3. Access the web server at http://localhost:5000 to configure your target currencies.

Project Structure

• lib/: Includes all the necessary libraries and modules.
• main/: Contains the main script and configuration files.
• web/: Houses the Flask web application files.

Wooden Box

This project features a sleek, minimalist wooden box, housing an e-paper display connected to a Raspberry Pi Zero, carefully crafted with CNC precision. It elegantly presents real-time currency exchange rates on your desk, combining functionality with a touch of natural aesthetic, thanks to its refined post-processed wood finish. The post-processing included grinding and finishing the process with wood oil to achieve a slight gloss.
