⚡ PaperFlux: thermal printer for GitHub stats

PaperFlux is a connected thermal receipt printer that outputs weekly GitHub activity summaries on paper. Developed by Alban Petit and covered by Open Electronics, the device targets developers seeking physical metrics of their coding progress. The unit prints a receipt listing stars, followers, commits from the last seven days, programming languages, and main repositories.

The hardware relies on a custom board measuring 33.55 x 50.05 mm. This compact form factor centers on an Espressif ESP32-C3-MINI-1 microcontroller module. The design integrates thermal printing capabilities to deliver tangible data without requiring a screen or mobile application for viewing the summary.

The project highlights the utility of small form-factor IoT devices for personal productivity tracking. By leveraging the ESP32-C3, the device maintains connectivity to fetch repository data while driving a thermal print head. The output format mimics traditional retail receipts, providing a nostalgic yet functional interface for software development statistics.
