Hackaday Supercon 2026 Billboard Badge
ESP32-S3 badge with a recycled 9.7-inch black, white, and red e-paper panel
The Billboard Badge is the official Hackaday Supercon 2026 badge, published on November 6, 2026, the event's Friday badge-hacking day, in the Hack-a-Day/2026-Billboard_Badge repository. Its README describes a 9.7-inch Pervasive Displays E2969JS0B1 e-paper panel, recycled from price tags destined for a now bankrupt German department store chain, driven by an ESP32-S3, with three SAO ports, eight WS2812-compatible LEDs, and four buttons. The stock MicroPython firmware shows the Supercon schedule, works as a digital name tag, and cycles through Hackaday art. Earlier teasers had promised a bigger badge with the biggest e-paper display that you've ever seen. The event closed on November 8 with a livestreamed badge-hacking and SAO contest prize ceremony; no handout count has been published.
