Open Source Badge Bitcoin Amsterdam
The badge of Bitcoin Amsterdam 2026, designed and built by us: an 18 LED bitcoin logo and an ESP32-S3 screen that swaps contact cards with other badges, lights up when someone zaps you, mines solo and shows how a seed is born. One run of 100, and no second batch.
