source-backed
Signed OTA firmware challenge
TechMaker describes OTA firmware updates with digital-signature verification, key recovery from badge information, and participant-signed firmware as a CTF path.
NoNameCon 2020 Air Quality Badge
source-backed
CAN and Shitty Addon expansion footprints
TechMaker documents a CAN-transceiver footprint for a CJMCU-2551/MCP2551 module plus a Shitty Addon Connector v1.69bis expansion header.

source-backed
ESP32-WROOM-32D custom badge core
TechMaker says the 2020 badge moved away from ready-made dev boards to a custom board built around Espressif's ESP32-WROOM-32D module.
NoNameCon 2019 NoNameBadge
source-backed
ESP32 Wi-Fi/Bluetooth badge core
The TechMaker writeup says the team chose a platform with Wi-Fi and Bluetooth, and the public firmware archive preserves an ESP-IDF project for the NoNameBadge.
Operational history
Issues & Camp Impact
The public firmware and write-up repositories document major badge CTF surfaces, but this pass does not prove that every private backend, provisioning script, factory image, key, leaderboard implementation, or organizer service has been published.
Software claims stay limited to the recovered TechMaker post, public firmware tree, public CTF writeups, and talk material.
The public firmware archive omits the private CTF portion by TechMaker's own framing, and the CTF write-up repository reconstructs public challenge paths rather than proving that every backend, provisioning, leaderboard, key, or organizer service was released.
Software claims stay limited to the recovered TechMaker article, public firmware tree, schematic, and CTF write-up repository.
No NoNameCon 2019 NoNameBadge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The Ukraine record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
No NoNameCon 2020 Air Quality Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The Ukraine record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The event listing presents NoNameCon 2020 as online and the TechMaker article says some CTF tasks were reworked because of COVID social distancing and the absence of the offline part of the conference.
The record documents a real badge platform but avoids claiming ordinary on-site pickup, universal in-person attendee distribution, or full offline village behavior.
The making-of documents production delays, hand assembly, volunteers, rejected or reworked ESP32 boards, self-test/update workflow, and last-week badge readiness rather than a frictionless manufacturing run.
The record preserves the practical production history and avoids presenting the badge as a fully polished commercial batch.
The public firmware project is useful evidence, but the GitLab project exposes no README URL in the project metadata and no top-level reusable image-license basis was recovered in this pass.
Repository files and article photos are cited as evidence only; no badge image is copied locally without explicit image rights, attribution, and processing provenance.
The public firmware project and TechMaker article are strong evidence, but no complete reusable image-license, attribution, source URL, and processing-provenance basis was recovered for publishing article photos or GitLab project imagery locally.
The record stays image-free until a rights-cleared original photo or official upstream raster render is recovered.
