End Summer Camp

End Summer Camp {21}

The September 2-7, 2025 Italian nonprofit hacking, free-software, and DIY camp in San Donà di Piave. Its organizer-owned badge-2025 repository explicitly identifies the flex-PCB BadgESC{21} as distributed at the camp and preserves hardware, firmware, case, and folding material under scoped licensing; event-wide recipient count, final production state, and reusable-image evidence remain unreported.

BadgESC{21} Badge

A completed Italian End Summer Camp {21} electronic badge whose organizer-owned badge-2025 repository explicitly calls it a flex-PCB badge distributed at ESC{21}. The public archive includes KiCad hardware, Gerbers, a BOM, placement data, folding material, a case directory, and firmware material; an author retrospective and first-person maker project document a transparent PET board folded into a cube. Public sources do not establish a recipient total, final unit-by-unit configuration, safety certification, a unified final firmware release, or reusable image provenance.

Lifecycle

Add-ons & Upgrades

BadgESC{21} Badge designer retrospective and maker-project context

documented electronics

ESP32-C3 LED and sensor surface

The public technical accounts identify an ESP32-C3, 42 WS2812B LEDs, an I2S microphone, and an accelerometer described as work in progress. They do not establish final component substitutions, feature enablement, calibration, electrical limits, all-unit parity, or a production BOM beyond the public archive's scope.

Compatibility: BadgESC{21} documented design context only; no expansion, pinout, repair, or external-device compatibility claim

BadgESC{21} Badge public configuration and project documentation

firmware context

WLED lighting and audio-reaction source context

The organizer directory preserves WLED-related material and the first-person maker project describes WLED/SoundReactive context. This records a public software lineage without repeating configuration details, claiming final deployed settings, or presenting a support, privacy, or operating guarantee.

Compatibility: Source-bounded BadgESC{21} project context; no claim of current service availability or universal deployed configuration

BadgESC{21} Badge schematics licensed CERN-OHL-S v2

open-hardware source archive

Public hardware-production archive

The organizer hardware tree exposes KiCad project files, rendered schematics, Gerbers, BOM, and placement data. The repository's licence statement is preserved as a schematics/hardware source condition only; it does not independently license every repository file, firmware component, photo, render, or external image.

Compatibility: Public organizer archive; downstream fabrication, electrical review, rights, and final event-unit status remain outside this catalogue claim

BadgESC{21} Badge documented completed 2025 event artifact

physical badge design

Transparent PET flex-PCB cube form

The organizer archive and designer retrospective document a transparent PET flexible board intended to fold into a cube, with case and folding material published alongside the design. This is a source-backed physical form, not a claim that every unit was identically folded, undamaged, assembled, or safe to modify.

Compatibility: BadgESC{21} event artifact and published project material; no generic flex-PCB or enclosure compatibility claim

Operational history

Issues & Camp Impact

BadgESC{21} Badge note

distribution, recipient, and event allocation boundary · organizer repository wording · badge described as distributed; allocation record unrecovered

The organizer repository explicitly says the flex-PCB badge was distributed at ESC{21}, but the reviewed public sources do not state how many were made, which ticket or role received one, whether every attendee was eligible, what variants existed, who collected one, whether units were retained, or the final delivery outcome.

The catalogue calls this a completed event artifact without turning a distribution statement into an attendee-wide entitlement, precise production number, recipient ledger, or uniform delivery claim.

BadgESC{21} Badge note

flex-PET, battery, USB-C, and assembly safety boundary · designer retrospective and organizer documentation · design context public; certification and safe-use evidence unrecovered

The reviewed project sources describe a foldable PET board, rechargeable power context, and physical connector/assembly considerations, but do not provide product-safety certification, electrical test results, charging validation, repair/rework guidance, regulatory status, or a universal safe-use outcome. Public design files are not treated as independently verified build or safety instructions.

The record preserves the documented artifact without implying that it is certified, risk-free, suitable for unsupervised modification, or a substitute for qualified technical review.

BadgESC{21} Badge note

hardware-license, firmware-license, and image-rights scope · organizer repository licence statement · schematics licence published; broader asset rights unresolved

The organizer repository says its schematics are licensed under CERN-OHL-S v2, but the reviewed sources do not establish a single licence covering every firmware component, case file, photograph, screenshot, project image, or upstream render. No selected badge image has the required source URL, reusable licence or explicit permission basis, attribution, and processing provenance.

The catalogue may describe the source-backed hardware archive but publishes no image and does not treat a hardware licence as blanket permission to reuse media or unrelated project files.

BadgESC{21} Badge note

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

No BadgESC{21} 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 Italy record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

BadgESC{21} Badge note

production-panel and final-unit variation boundary · first-person maker-project observation · limited panel-quality observation published; aggregate outcome unrecovered

The first-person project notes that some transparent panels overheated or wrinkled during production while units were worked on at camp. The reviewed sources do not quantify affected units, identify all causes, describe final remediation, publish quality-control results, or establish that every distributed unit had the same condition or configuration.

The catalogue retains a narrow documented production caveat without presenting it as a defect rate, recall, safety finding, or universal final-unit characteristic.

BadgESC{21} Badge note

wireless, WLED, and privacy configuration boundary · public repository and maker-project context · software lineage documented; final deployment configuration unrecovered

The project sources establish an ESP32-C3 and WLED-related material, but do not provide a reviewed final deployment snapshot for every badge's radio settings, network/service configuration, access controls, telemetry, data retention, privacy practice, update policy, or post-event availability. No credentials or operational configuration details are reproduced here.

The entry records the source-backed software context without asserting a particular network behavior, service, privacy posture, security property, or current operational endpoint.

BadgESC: Unfolding the Power of FlexPCB designer technical retrospective · Jacopo Franco's first-person retrospective documents the clear PET flex-PCB concept, fold-to-cube form, ESP32-C3, 42 WS2812B LEDs, audio/sensor development context, custom cell, and production process. It is used for those source-bounded technical claims, not as safety certification, a recipient count, or image-reuse permission. Fully Transparent Folded Cube Badge first-person maker project · Jacopo Franco's Hackaday.io project identifies the ESC{21} badge as clear-PET, LED-loaded conference hardware and records a limited production-quality observation. The project does not establish all-unit parity, an event allocation total, a final support lifecycle, or rights to reuse project media. End Summer Camp {21} registration official event registration · The official 2025 registration identifies End Summer Camp {21} as a September 2-7 nonprofit hacking, free-software, and DIY gathering at ART2 Lounge / Parco della Scultura in Architettura in San Donà di Piave. It establishes event context, not the badge's technical design, allocation, production total, or image rights. End Summer Camp badge-2025 repository organizer source archive · End Summer Camp's public repository explicitly says it contains schematics for the flex-PCB badge distributed at ESC{21}. Its root tree links hardware, firmware, case, and folding material, but it does not provide a recipient ledger, final production report, or blanket reuse permission for repository media. BadgESC{21} firmware directory public firmware-material directory · The organizer repository preserves WLED-related configuration and build material. It does not by itself establish a tagged final firmware release, a source-to-unit mapping, deployment settings, a whole-firmware license, or a supported operating procedure. BadgESC{21} hardware source tree public hardware design archive · The organizer archive preserves native KiCad project material, rendered schematics, Gerbers, BOM, and placement data. These sources document public design material, not a uniform final unit, manufacturing outcome, electrical certification, or safe modification result.
