The DEF CON 33 BiC Village BIC Pick badge (walkthrough by Eli McCrae) is a solderable Afro-pick–shaped badge using a Waveshare ESP32-S3, 18 NeoPixels and SAO headers. Users connect via serial or badge.shift.us (Web Serial API) with AT-style commands to access a filesystem, logic-analyzer, GPIO, Badgenet interbadge networking and integrated CTFs (DC NextG and Big Village challenges).
