2026

Fri3d Camp 2026 Badge

Completed-camp ESP32-S3 maker badge with open Revision 02 hardware

A source-backed record for Fri3d Camp 2026's main badge. The organizer's public Revision 02 hardware, firmware, and documentation repositories describe an open ESP32-S3 platform with extensions, apps, and repair paths; the organizer's event index now lists the August camp among past events. Neither source establishes individual handout, production, or final deployed-image outcomes.

Operational history

Issues & Camp Impact

Fri3d Camp 2026 Badge moderate

safety and modification caveat · official hardware and add-on documentation · documented guidance; field outcome unrecovered

The official documentation says the analog multimeter connector has no protection, warns against operating the optional LoRa module without an antenna, and notes that the 2000 mAh LiPo is mechanically less robust than prior 18650 cells and is protected by a cover. The optional radio and expansion paths also require soldering.

The record presents the expansion surface as intentional maker hardware, not risk-free plug-and-play peripherals.

Fri3d 2024 Badge note

Arduino partition and reset caveat · primary docs · documented

The Arduino guide says the custom fri3d-esp32 package writes sketches to the MicroPython partition and relies on the default firmware to start that partition; overwriting the default firmware requires the reset guide to return.

Fri3d 2024 has multiple programming paths, but they are not equivalent: users need to understand whether they are using the managed MicroPython partition or replacing the default firmware.

Fri3d 2022 Badge note

community-port input caveat · community repository · documented

The nofrendo port documented working display, buzzer audio, SPIFFS ROM loading, and a START-button workaround, but also noted that more button configuration was still TODO because the badge did not have buttons.

The page separates an impressive post-event software port from a complete game-console experience.

Fri3d Camp 2026 Badge note

completed-camp handout state · official 2026 camp and hardware repositories · camp completed; handout and production outcome unverified

The organizer event index lists Fri3d Camp 2026 among past events. The hardware README says Revision 02 was the version intended for handout during the camp, but neither source establishes individual attendee distribution, final allocation, physical-unit parity, or field reliability.

The catalogue can mark the event complete without converting a planned handout statement into a completed attendee-distribution or production claim.

Fri3d 2016 Badge note

documentation completeness · primary writeup and archived repo · historical caveat

The surviving public record is strong enough to seed the badge, but the archived repository and writeup do not provide the same polished end-user documentation depth as later Fri3d badge years.

The dossier should stay conservative until photos, final attendee firmware notes, and any workshop pages are recovered.

Fri3d Camp 2026 Badge note

firmware and app release boundary · official documentation and MIT firmware repository · partly documented / post-event source pass

The public firmware and App Store paths establish a programmable platform, but they do not prove the final attendee firmware image, final pre-installed app set, App Store inventory or availability during camp, final game payloads, or post-event support. The firmware README also documents a manual headset-output configuration choice.

The catalogue records the released software architecture and recovery workflow without converting a public repository into claims about final attendee experience.

Fri3d 2016 Badge note

image provenance upgrade · project writeup image and page license footer · licensed original replacement applied

The Fri3d 2016 visual now uses an optimized WebP derived from Christophe VG's `fri3d-badge.jpeg` project-writeup header image.

The public badge page, image archive, and API point at a source-page image with exact URL, CC BY-SA 4.0 license basis, attribution, and processing notes while avoiding generated, placeholder, social, or uncleared imagery.

Fri3d 2024 Badge note

image provenance upgrade · project image provenance and repository license · licensed original replacement applied

The Fri3d 2024 visual now uses an optimized WebP derived directly from the Apache-2.0 `docs/badge2024.jpg` photo in the official Fri3dCamp badge repository.

The public badge page, image archive, and API point at a licensed original-photo derivative with source and attribution preserved.

Fri3d 2022 Badge note

image provenance upgrade · project image provenance and repository license · licensed upstream raster replacement applied

The Fri3d 2022 visual now uses the transparent upstream `media/Badge_02_Front_NoBG.png` asset from the official Fri3dCamp badge hardware repository.

The public badge page, image archive, and API point at a licensed upstream raster asset with source and attribution preserved.

Fri3d 2018 Ph0xx note

image provenance upgrade · project image provenance and repository license · licensed original prototype photo applied

The Fri3d 2018 visual now uses an optimized WebP derived from the official repository `media/Fri3dBadge_2018_00_Proto0.jpg` documentary photo of real Ph0xx prototype boards.

The public badge page, image archive, and API point at a source-controlled original photo with source URL, license basis, attribution, and processing notes while avoiding generated, placeholder, social, or uncleared imagery.

BruCON 0x0A Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No BruCON 0x0A 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 Belgium record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

Fri3d 2018 Ph0xx note

power/safety caveat · primary project docs · historical

The 2018 badge used 18650 power, so power handling and charging context should be preserved alongside the fun fox/jewel lore.

Useful context for comparing later camp badge battery and safety decisions.

BruCON 0x0A Badge note

production crunch · event retrospective · historical

Organizers reportedly stayed awake through the night soldering the badges before the event.

This preserves the operational reality behind the badge, not just the attendee-facing utility.

Fri3d 2018 Ph0xx note

production throughput caveat · primary project log · historical

The Ph0xx mass-production log says the team started with prototype machinery, manual solder paste dispensing, and a three-zone reflow oven; quality was good but the process was too slow for the badge quantity.

Fri3d 2018 belongs in the operational history of camp badges: even a strong design still had small-run manufacturing throughput constraints.

Fri3d 2024 Badge note

recovery workflow · primary docs · documented

The 2024 docs explicitly include reset-to-factory and update paths, indicating recovery and firmware management were expected parts of badge ownership.

Good recovery docs reduce the risk that app or firmware experiments permanently strand an attendee's badge.

BruCON 0x0A Badge note

shipped firmware bugs · repository README · historical

The repository README explicitly points to the firmware version that was on the conference badge and notes that it is preserved with its bugs.

The archive should treat the tagged release as historically important even where later source changes may differ from the build attendees actually used.

BruCON 0x0A Badge note

source-depth caveat · event retrospective and repository review · schematic-backed review still useful

The repository review confirms the source tree, firmware release, KiCad/Gerber package, LCD, ADC, Wi-Fi, URL, menu, map, schedule, and server-side workflow, but the page still avoids unsourced chip-level claims that require careful schematic/BOM extraction.

The dossier is now stronger than a first-pass retrospective record while still keeping component lists tied to inspectable files.

Fri3d 2022 Badge note

source-depth caveat · mixed sources · needs deeper recovery

The 2022 record is currently seeded from public docs, repositories, and supplier coverage, but detailed per-app lore needs more event-specific source recovery.

The page should be expanded with original workshop/app pages where available.
