BugCON 2022 Badge

RP2040 audio, microphone, LEDs, and EdgeImpulse badge

BugCON 2022's Electronic Cats badge repository documents an RP2040 electronic badge for BugCON 2022 CDMX with USB serial access, LEDs, microphone, buzzer or speaker, a small machine-learning trail through EdgeImpulse, Arduino Mbed programming notes, KiCad hardware files, and Blink/AudioWAV firmware examples.

Why It Mattered

It fills an earlier Mexican BugCON badgelife point before the 2024 ESP32-C6 and 2025 Linux badges, showing a Latin American conference badge that mixed RP2040 hardware, audio output, microphone input, serial interaction, and public hardware/firmware archives.

Hardware

The README lists RP2040, USB, LEDs, microphone, and buzzer or speaker. The KiCad schematic further preserves an RP2040, SPH0641LM4H microphone, PAM8302AAD audio amplifier, W25Q16JV flash, MCP1700 regulator, micro-USB connector, battery cell, four LED references, buzzer, BOOT solder jumper, RESET switch, and KiCad PCB/schematic files.

Software & Apps

The README tells attendees to connect the badge over USB, open a serial terminal at 115200 baud, observe the terminal startup, and type `help` for more commands. It points Arduino developers to the project wiki and the Arduino Mbed RP2040 core. The firmware tree preserves Blink_Bug, AudioWAV, a `Chona.wav` asset, USB mass-storage / PWM audio demo code, and an EdgeImpulse audio-classification note.

Lore

The Spanish README frames the badge as an insignia from a new order, says security is only a myth, and states that Electronic Cats created an electronic badge for BugCON2022 in CDMX as part of #badgelive.

Operational history

Issues & Camp Impact

event-context depth caveat note

The repository metadata and README prove a BugCON 2022 CDMX electronic badge, but this pass did not recover a stable official BugCON 2022 event page, ticket page, schedule page, distribution count, or venue source.

Event claims stay bounded to BugCON 2022 CDMX and the public badge repository instead of inventing dates, venue, ticket tier, or distribution scope.

Confidence: repository metadata and README
Status: needs archive/event-page recovery
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-BugCON-2022 repository metadata, README, and current BugCON site recheck.

firmware-source caveat note

The firmware tree preserves Blink_Bug, AudioWAV, Chona.wav, and an EdgeImpulse note, but this pass did not audit every sketch dependency, runtime command implementation, challenge binary, audio asset provenance, or final shipped firmware image.

Software claims stay tied to the README instructions, visible firmware tree, and decoded example sketches rather than treating the repository as a complete final production firmware archive.

Confidence: repository tree and decoded sketches
Status: needs deeper firmware inventory
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-BugCON-2022 firmware tree, Blink_Bug sketch, AudioWAV sketch, and Edge_impulse.txt.

license-file caveat note

The README says hardware is released under CERN Open Hardware Licence v1.2 and says to consult a LICENSE_HARDWARE file, but this pass found no top-level `LICENSE_HARDWARE.md` through the GitHub contents API and GitHub reports no detected repository license.

The catalogue can cite the README's open-hardware claim and public source while avoiding assumptions that firmware, photos, readme images, logos, KiCad renders, or other repository media are reusable publication assets.

Confidence: GitHub API and repository README
Status: documented with caution
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-BugCON-2022 README, repository metadata, GitHub contents API 404 for LICENSE_HARDWARE.md, and badge.gallery image policy.

missing rights-cleared image note

No BugCON 2022 badge image is published because the README logo, repository media, site graphics, screenshots, and hardware-source render candidates have not been paired with complete reusable image rights, attribution, source URL, and processing provenance for catalogue publication.

The entry remains source-backed and image-free rather than copying event logos, README images, GitHub assets, KiCad screenshots, social photos, or generated imagery without complete provenance.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and ElectronicCats/Badge-BugCON-2022 repository.
