Bitcoin is the most profoundly apolitical political treatise ever written.

Honestly, I have no idea if I did this right! I flashed a script onto a $15 wireless e-paper tag (the kind used for store price labels) so it displays the BTC/USD price, updating every two minutes. Is it overkill? Probably. Is it beautiful? Absolutely. Is it Bitcoin? Yes. Code is public, repo is open.

GitHub - vaccotti/BTC-USD-E-Ink-Ticker-Heltec-Wireless-Paper-V1.2-ESP32-S3: A minimalist, always-on Bitcoin price ticker using an e-ink display. This project fetches the BTC/USD price and 24h percentage change from Binance’s public API and displays it on a Heltec Wireless Paper V1.2 using an ESP32-S3. The screen refreshes every 2 minutes and retains the last image even when powered off. Don’t trust, verify.

Open source. Everything. If money is just information, this is what it should look like. Stay humble. Stack sats. Build weird stuff. 🧡
