ESP32-C3 badge with Badge Clinic and MicroPython workflow
The HOPE XV Electronic Badge was issued to in-person attendees as an ESP32-C3 badge with purple attendee boards, black pro boards, case variants, 16 WS2812-class RGB LEDs, buttons, IR blast behavior, vibration feedback, open hardware files, and MicroPython hacking notes.

SourceOfficial HOPE pages and the HOPE wiki establish the event context, schedule, venue, and electronic badge documentation.
SourceIt brings the New York HOPE lineage into the worldwide compendium as a modern North American conference badge where the event itself supported badge repair, assembly, classic-badge discussion, firmware experimentation, and open hardware continuity through The Badge Clinic.
The official HOPE wiki documents an ESP32-C3 microcontroller, 16 WS2812 or similar RGB LEDs, an MCP73871 LiPo charge controller, IR LED behavior, vibration motor feedback, multiple attendee/pro board and case variants, unpopulated components in the BOM, and two SAO-style connector positions in the KiCad-derived bill of materials.
The HOPE wiki links firmware and ESPHome paths, documents MicroPython flashing for ESP32-C3 via esptool.py, serial console access, mpremote file-copy and run workflows, LED NeoPixel snippets, button snippets, and a warning that replacing firmware can erase the HOPE firmware image.
The HOPE XV schedule records both ongoing Electronic Badge Hacking and The Badge Clinic across the event, with Badge Clinic nurses helping attendees assemble, repair, explore features, hack badges, and discuss HOPE electronic badges plus other hacker-con badge artifacts.
Lifecycle
The wiki says the fourth button sends an IR blast to nearby badges, making their lights flash and motor vibrate.
SourceThe official schedule and wiki describe a Badge Clinic where attendees could get help with assembly, features, repairs, hacking, and historical badge questions.
SourceThe wiki points badge hackers to an ESPHomeBadge path as an alternative way to write firmware for the HOPE XV badge.
SourceThe wiki documents erasing and flashing ESP32-C3 MicroPython firmware, using serial console access, running scripts with mpremote, and copying code to run at boot.

SourceOperational history
The catalogue records verified hardware and hacking surfaces while leaving complete firmware and variant preservation for a later artifact-level pass.
The record now has a rights-cleared official upstream raster render with source URL, CC BY-SA 4.0 component license, attribution, local source preservation, and optimized WebP delivery while keeping the wiki's unlicensed front/back photos unpublished.
The catalogue records the public open-hardware path while avoiding stronger claims about every production file until a deeper repository audit is done.
