PurgeClock

A retro sci-fi CRT clock, weather terminal, and emergency environmental purge alarm console built in Python. Designed to run directly on the Raspberry Pi Linux framebuffer (/dev/fb0) from the console or TTY without an X11/Wayland desktop environment.

Features

• Green HUD Terminal: 7-segment digital clock with AM/PM indicator, live date, custom targeting reticles, border ticks, and telemetry data.
• Live Weather Integration: Automatically fetches temperature, humidity, wind speed, and conditions via Open-Meteo API in an asynchronous background thread.
• Emergency Purge Alarm: Recreates the classic Nostromo Environmental Control screen (ENVIRON CTR // PURGE // 24556 DR 5) with a pulsing crimson backdrop and strobe effects.
• Multiple Alarm Triggers: Supports manual keyboard toggles (Space/P), daily scheduled alarms (--alarm-time HH:MM), and periodic simulation intervals.
• Zero Heavy Font Dependencies: Vector-rendered segmented typography.

Quick Start

1. Install Pygame

sudo apt-get update sudo apt-get install -y python3-pygame

2. Grant framebuffer permissions

sudo usermod -a -G video $USER
