BTC Ticker

A minimal Bitcoin price ticker that runs on a Raspberry Pi and displays the current BTC/USD price on a Waveshare 2.13" e-ink display. On startup it shows a Bitcoin logo, then enters a loop that refreshes the price every 5 minutes. The background alternates randomly between black and white on each refresh.

• Fetches live BTC/USD price from a configurable API endpoint
• Renders price in large, high-contrast text on a 2.13" e-ink panel
• Alternates black/white background on every refresh for visual variety
• Runs as a systemd service — starts automatically on boot
• Watchdog integration via sd_notify for reliable restarts
• Installable Python package with a clean hardware abstraction layer
