NoNameCon 2019 NoNameBadge
A Ukrainian NoNameCon 2019 electronic badge built by TechMaker around an ESP32 platform with Wi-Fi/Bluetooth, OLED display, LEDs, capacitive input, OTA firmware, SpyNet backend interaction, and a six-flag badge CTF.

NoNameCon 2019 NoNameBadge
released
Collaborative CTF write-up archive
The public CTF repository preserves write-up entry points for Rooting, Mr Bean Walker, BruteSearcher, NoNameCon SpyNet, Ployka PWNer, Binary Hero, and Side Blennel.

OLED, LEDs, and capacitive input
The making-of and source tree document OLED firmware, LED behavior, capacitive-button/self-test production flow, and WS2812 control modules.

SpyNet backend interaction
The badge CTF story used a SpyNet server that logged badge activity and exposed web/application-security challenge material.

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.

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.
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.
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.
