Lifecycle
Add-ons & Upgrades
Disobey 2026 Badge
source-backed
Social game firmware and miniapps
The badge page describes social-game firmware for badge-to-badge duels and asks miniapp authors to submit pull requests so apps can be built into shared firmware.
Disobey 2026 Badge
source-backed
CTF challenge firmware station
The official page documents a second CTF firmware path and a flashing station near the CTF area, with source release promised after the event.
Disobey 2026 Badge
source-backed
Hardware mod and miniapp competitions
The competition rules solicit hardware mods, 3D models, apps, games, and standalone firmware for the badge, and list public hardware-mod submissions.
Disobey 2026 Badge
source-backed
Minimal OTA first-use firmware
Badges shipped with minimal firmware for hardware testing and OTA update; the official page documents event-WiFi provisioning and a web-flash fallback if OTA failed.
Disobey 2026 Badge
source-backed
ESP32-S3 TFT badge core
The hardware docs document ESP32-S3 WROOM-2, a 1.9-inch ER-TFT019-1 display, SK6812MINI RGB LEDs, joystick/buttons, GPIO mapping, schematic v11, and STEP mechanical model references.
Disobey 2026 Badge
source-backed
Post-event 3D-printed hardware mods
The official badge page lists public Best Hardware Mod submissions, including 3D-printable battery holder and case approaches for carrying or protecting the badge.
Disobey 2026 Badge
experimental
Experimental LED extension firmware
The official page links a post-event experiment for controlling extra addressable LEDs from the badge through WLED-style firmware work.
Disobey 2026 Badge
source-backed
Rust games and demos
The Rust repository documents badge examples including Breakout, Skyroads, Snake, Space Shooter, demoscene, shader, vector demo, display tests, LED bars, microphone, name-tag, scrolling, vibration, and async task-switch examples.
Disobey 2026 Badge
source-backed
Rust support library
The MIT-licensed disobey2026badge crate and repository expose Rust APIs for the ST7789 display, nine GPIO buttons, WS2812 LEDs, display backlight, and vibration motor.
Operational history
Issues & Camp Impact
Disobey 2026 Badge
moderate
The badge page warns attendees to handle the badge carefully because the screen can be damaged if the badge is dropped or treated roughly.
The physical artifact has a documented handling caveat that belongs with the hardware record.
Disobey 2026 Badge
note
The official badge page still says the CTF challenge firmware source code will be released after the event, but the public sources checked in this pass did not expose that release.
The catalogue keeps the CTF flashing-station workflow as source-backed event behavior while avoiding a false claim that the CTF firmware source has already been published.
Disobey 2026 Badge
note
The official page says the badges were originally supposed to arrive before Disobey 2025 and finally arrived for Disobey 2026.
The record uses the 2026 event edition while preserving the 2025/2026 naming split found in the badge URL and repository.
Disobey 2026 Badge
note
The post-event LED extension path is documented as experimental firmware work rather than an official shipped attendee feature.
The record preserves the WLED-style extension idea while avoiding a claim that all badges shipped with that behavior or that it was part of the event firmware baseline.
Disobey 2026 Badge
note
The official badge page lists public hardware-mod submissions but still leaves the Best Miniapp competition entries as coming soon.
The catalogue can cite the competition workflow and hardware-mod entries, but should not claim a complete public miniapp archive until the official page or repository publishes it.
Disobey 2026 Badge
note
No local Disobey 2026 badge image is published because the official badge page images have not been paired with an explicit reusable license, attribution, and processing provenance for catalogue publication.
The Finnish record stays source-backed and image-free rather than copying official-page imagery, screenshots, social photos, or generated artwork.
Disobey 2026 Badge
note
The repository README says the project uses submodules with various licenses and instructs readers to check individual component licenses.
Firmware and hardware facts can be sourced from the repository, but code-reuse and asset-reuse claims should not be collapsed into one blanket license statement.
