Hackers On Planet Earth
The 15th Hackers On Planet Earth conference, held July 12-14, 2024, where an ESP32-C3 electronic badge, Badge Clinic, open hardware repository, firmware paths, and MicroPython hacking notes were documented through official HOPE sources.

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.
Lifecycle
The wiki says the fourth button sends an IR blast to nearby badges, making their lights flash and motor vibrate.
The official schedule and wiki describe a Badge Clinic where attendees could get help with assembly, features, repairs, hacking, and historical badge questions.
The wiki points badge hackers to an ESPHomeBadge path as an alternative way to write firmware for the HOPE XV badge.
The wiki documents erasing and flashing ESP32-C3 MicroPython firmware, using serial console access, running scripts with mpremote, and copying code to run at boot.
The HOPE wiki documents an ESP32-C3 badge core with 16 WS2812-class RGB LEDs and attendee-facing light-pattern controls.
Operational 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local source preservation, and optimized WebP delivery while keeping the wiki's unlicensed front/back photos unpublished.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.
