Area41 2026 ESP-Based Electronic Badge

Swiss ESP blinking attendee badge with SAO invitation

A source-backed Area41 2026 attendee electronic-badge record. The official event page said each attendee would receive an ESP-based blinking electronic badge and invited badge owners to bring Shitty Add-Ons (SAOs). The organizer's post-event recap identifies Technische Fachschule Bern as the badge designer and assembler, while the school's own update says it developed and manufactured the hardware; the recap also reports attendees soldered more than 300 SAO badge extensions.

Carolina Code Conference 2026 Circuit Board Badge

Completed ESP32-S3 CircuitPython conference badge with public source

Carolina Code Conference's organizer documented Circuit Board Badge pickup for its August 14-15 event, and its named badge partner published a source archive for an ESP32-S3 CircuitPython board. The archive identifies five WS2812 LEDs, three buttons, a 1.77-inch ST7735S display, Micro-USB, and CR123A or USB power. It supports a released badge software and hardware reference, not a recipient ledger, an independently audited final production configuration, or a rights-cleared physical-badge image.

Workday DevCon 2026 Blinky 2350 Badge

Post-event Pimoroni Blinky 2350 developer-conference badge; organizer allocation unverified

A public post-event app archive by Mainak Sarkar identifies a Pimoroni Blinky 2350 badge as handed out at Workday DevCon 2026 and says it ran the badgeware MicroPython operating system and app launcher. Workday's official pages establish the completed June 1-4 Las Vegas developer conference, but do not directly document badge issuance, recipient allocation, custom hardware, event firmware, or image rights. This is therefore a source-backed event badge record with intentionally limited organizer attribution.
