Cyb3rBytes404 Cyber-Cat Badge (DEF CON 34)

Small-batch pre-event RP2040 youth-coding giveaway badge for DEF CON 34

A late-July public r/Defcon post by u/ProfessionalPea2218 says its author has been designing and hand-soldering a small batch of badge PCBs to help launch Cyb3rBytes404, a self-described San Diego nonprofit for free hands-on youth coding and electronics projects. The author says the badges are not for sale and are intended for random giveaway throughout ‘the con.’ Separately, the public Cyb3rBytes404 GitHub repository calls itself the official repository for the cyber coding camp and documents a custom RP2040 cyber-cat badge, MicroPython starter material and challenges, an MPU-6050 motion module, and thirty WS2812 RGB LEDs. Its visible commit history places the reviewed README update on July 28, 2026. The shared project name supports a source-backed pre-event DEF CON 34 association, but it does not establish that the Reddit author controls the GitHub namespace, that every physical PCB matches the repository snapshot, final hardware, the run size, a completed giveaway, or a DEF CON-issued credential.

Authors & Credits

public coding-camp repository publisher

Cyb3rBytes404

The public GitHub namespace publishes the repository that calls itself the official source for the Cyb3rBytes404 cyber coding camp. This is a repository-publisher credit only; it does not establish a legal entity, nonprofit status, connection to the Reddit author, individual hardware/code/art authorship, manufacture, DEF CON role, distribution responsibility, or image-reuse authority.

public first-person maker-post author

u/ProfessionalPea2218

The public Reddit account says it designed and hand-soldered the described badge PCBs. This records a narrow post attribution and does not identify the person's legal identity, relationship to the Cyb3rBytes404 GitHub account, formal nonprofit role, authorship of repository code/artwork, production responsibility, DEF CON affiliation, or image-reuse authority.

Why It Mattered

The record preserves a current educational maker-giveaway project that would otherwise disappear into a social-media post, while keeping its evidence boundaries unusually clear. A first-person physical-build statement and a named public software repository can be cited together without equating their account identities, treating starter code as a final event image, or turning an independent small-batch plan into an official conference handout.

Hardware

The immutable July 28 repository README names a Raspberry Pi RP2040 microcontroller, an MPU-6050 three-axis gyroscope/accelerometer module, and thirty WS2812 RGB LEDs for a custom cyber badge. The maker post separately says badge PCBs were designed and hand-soldered. Neither source identifies an exact RP2040 board/package, sensor or LED variant, PCB shape/artwork, LED wiring/current budget, power source or path, USB connector behavior, inputs, storage, connectors, schematic, BOM, PCB/Gerbers, dimensions, materials, assembly/test record, safety guidance, compliance, production revision, or final physical-unit parity.

Software & Apps

The public repository exposes MicroPython starter scripts, a helper library, and educational code-challenge material for the named cyber badge. The catalogue records only that high-level source surface; it does not reproduce connection, installation, flashing, editor, pin, challenge, or operating steps. The public GitHub release page reported no releases in this source pass, and no reviewed source establishes a final event-unit image, tagged binary, source-to-unit mapping, dependency lock, build result, update/recovery policy, support commitment, security review, data practice, or code/media reuse grant.

Lore

Cyb3rBytes404 frames the artifact around a cyber-cat mascot and free hands-on youth learning. The first-person r/Defcon post calls the physical run small, says it is not for sale, and plans random giveaways ‘throughout the con.’ DEF CON's official registration page independently supplies the August 6-9, 2026 Las Vegas context but does not name Cyb3rBytes404. These are pre-event project and distribution statements, not proof of nonprofit status, a final quantity, selection method, actual handoff, event authorization, organizer relationship, admission benefit, recipient list, or post-event outcome.

Issues & Camp Impact

firmware, release, and licensing boundary note

The repository exposes MicroPython teaching material, while its public GitHub release page reports no releases. No reviewed source establishes a tagged final firmware, binary, source-to-unit mapping, build/dependency state, firmware image on a giveaway PCB, update/recovery policy, security review, support commitment, data practice, code license, artwork license, or media reuse permission.

Public source visibility is recorded without treating it as a finished event release, reliable operating path, security assurance, or permission to copy code, artwork, project branding, photographs, or screenshots.

independent DEF CON association and credential boundary note

The maker posted in r/Defcon and refers to giving badges away throughout ‘the con’; DEF CON's official registration page independently establishes the August 2026 event. Neither source says DEF CON designed, commissioned, approved, issued, sold, or will distribute this artifact; neither establishes venue authorization, registration inclusion, admission, access control, or an official Human-badge role.

The catalogue classifies this as an independently documented pre-event project associated with DEF CON 34, not an official conference credential, organizer-issued badge, attendee entitlement, or verified event activity.

maker-post, repository, and project-identity boundary note

The first-person Reddit post names Cyb3rBytes404 while the GitHub namespace/repository uses the same project name, but neither reviewed source links the Reddit account to the GitHub account or identifies a legal person, nonprofit entity, hardware author, code author, manufacturer, or project owner across both surfaces.

The catalogue can cite the corroborating project-name trail without stating that u/ProfessionalPea2218 controls Cyb3rBytes404 on GitHub, authored all code, or holds any formal nonprofit, DEF CON, or media-rights role.
