BadgESC{21} Badge
Transparent PET flex-PCB cube conference 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.
Hackaday Europe 2026 Communicator Badge
Lecco reuse of the Supercon 2025 LoRa mesh badge
Hackaday Europe 2026 brought the 2025 Hackaday Supercon Communicator Badge to Lecco: a retro-styled keyboard badge with LoRa mesh experimentation, MicroPython/LVGL app support, and post-event Meshtastic reflash framing.
RISC-V Summit Europe 2026 FPGA Badge
SemiTO-V Developer Zone RP2350/GW1N-9 electronic badge project
SemiTO-V's RISC-V FPGA Badge was a limited Developer Zone electronic PCB badge project for RISC-V Summit Europe 2026 in Bologna. Primary team sources name an RP2350 MCU, a GOWIN GW1N-9 FPGA, custom firmware, and a default RV32I core; they say NextPCB produced the boards and planned to bring 25 to the developer workshop. A logistics update then delayed intended June 8 distribution. The source record supports real physical boards and a 2026 event association, not a final unit count, completed recipient delivery, or the precise current post-event design revision.
RomHack Camp 2026 Badge
Pre-event unique hardware badge challenge
A current pre-event record for the October 2-4, 2026 RomHack Camp at Flaminio Village, whose public event site and participant FAQ advertise a unique hardware badge and collectible challenge rather than final shipped hardware details.

Badge Hacking Ceremony
The official schedule data lists a Saturday 22:00 Badge Hacking Ceremony before the Hackaday Europe party.
BadgESC{21} Badge
public configuration and project documentation
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.
RISC-V Summit Europe 2026 FPGA Badge
README-linked projects; deployed build unrecovered
Public firmware references
The README points to pico2-editor and riscv-badge-displaylib. This record preserves their public-reference role without asserting version parity, a released binary, a deployed event image, programming steps, support ownership, or a recovery procedure.
Hackaday Europe 2026 Communicator Badge

RISC-V Summit Europe 2026 FPGA Badge
public native source
KiCad 10 open-hardware archive
The repository README identifies KiCad 10 and the archive exposes native PCB and schematic files. The open source tree is valuable documentation, but it is not a substitute for a reconciled physical production revision, assembly record, electrical-safety assessment, or delivery ledger.
RISC-V Summit Europe 2026 FPGA Badge
primary team source detail
RV32I firmware context
The team says the custom firmware includes a default RV32I core. This is recorded as high-level source context only, without operational FPGA configuration, programming, debugging, execution, or security claims.
MuHack Badge

NFC tag identity surface
The hardware list includes an NFC tag, making identity and near-field interaction part of the badge surface.
RISC-V Summit Europe 2026 FPGA Badge
25 boards planned; completed recipient handoff unrecovered
Developer Zone and 25-board source trail
SemiTO-V stated it would bring 25 badges to the Developer Zone workshop and later reported a logistics problem that prevented intended June 8 distribution. The sources establish a limited 25-unit Developer Zone badge run in planning and a real physical-board project, not a completed allocation ledger, attendee-wide issue, or confirmed recipient count.
Hackaday Europe 2026 Communicator Badge

Front-panel customization path
Hackaday's customization article frames the badge as built to be modified with replaceable front-panel mechanical files.
IHC 2018 1337 3310 WiFi
historical
Recycled Nokia 3310 shell
The badge's mechanical identity comes from turning old Nokia 3310 phone shells into camp badge enclosures while keeping the keypad and handheld form factor.
BadgESC{21} Badge
schematics licensed CERN-OHL-S v2
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.
BadgESC{21} Badge
documented completed 2025 event artifact
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.

Collectible badge challenge
RomHack Camp 2026 is currently advertised with a unique hardware badge and collectible challenge; final challenge mechanics are not yet public in the source set.
RISC-V Summit Europe 2026 FPGA Badge
August 3, 2026 source update; event-unit parity unconfirmed
current post-event V1.6 KiCad revision
Version 1.6 fixes listed in the August source commit demonstrate that the public design continued after the June summit. The current post-event V1.6 KiCad revision is therefore not presented as a photograph, render, or authoritative specification of every physical summit badge.
RomHack Camp 2022 Badge
historical
BLE badge radar
The badge advertised itself over BLE with a 1-7 ID and included radar and badge-list screens for discovering nearby badges in camp.
User app examples
The upstream repository preserves user-app examples and firmware docs for writing MicroPython applications on the Communicator Badge platform.
IHC 2018 1337 3310 WiFi

Optional ESP32 connectivity
The badge page lists support for an ESP32 board to add wireless capability beyond the RP2040 base badge.
Operational history
Issues & Camp Impact
Hackaday said the Italy experiment would use different frequencies and maybe push transmission parameters compared with Supercon.
The record should not imply identical RF operating conditions, channel plans, or range behavior between Pasadena and Lecco.
BadgESC{21} Badge
note
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.
Badge hacking depended on attendee-supplied USB and battery power.
The official page recommended a micro USB data cable plus replacement AA batteries or a power bank, so a prepared kit mattered for camp hacking.
The public KiCad archive and team posts name a controller and FPGA, but reviewed sources do not establish a reconciled manufactured BOM, component substitutions, exact power/battery architecture, charge/protection behavior, electrical limits, thermal result, assembly/test plan, compliance result, enclosure, connector map, or final populated-board condition for physical summit units.
The catalogue preserves the source-backed design trail without calling it a fabrication recipe, tested device specification, safety assessment, or compatibility guarantee.
MuHack Badge
note
The official badge page marks the MicroPython firmware section as in progress, so this dossier avoids claiming a complete app-store or polished firmware ecosystem.
The record should be revisited if the repository or project page publishes final attendee firmware, recovery, or app documentation.
The README links firmware-related repositories and team posts name custom firmware plus a default RV32I core, but the project repository has no tag or GitHub release and reviewed sources do not map a versioned build to physical summit boards, provide a final binary, define a support owner, or establish a recovery/update lifecycle.
The record describes public firmware context at a high level without presenting any current source checkout as deployed, supported, verified, or suitable for operation.
The public sources describe Europe use, MicroPython apps, LoRa experimentation, and Meshtastic reflash framing, but this pass did not recover a distinct Lecco-specific firmware release archive.
Software claims stay tied to the public Europe articles and upstream Communicator Badge firmware repository rather than a separate Europe firmware tag.
BadgESC{21} Badge
note
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
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.
The published image is the MIT-licensed upstream Communicator Badge repository front photo, duplicated under a Hackaday Europe 2026 delivery filename for the reuse record.
The image proves the physical badge platform, not a separate Lecco documentary field photo; any event-floor photo should be added only with its own source URL, license, attribution, and processing notes.
The RomHack Camp 2022 visual now uses the transparent upstream `img/RHC22_badge_front.png` front render from the public MIT-licensed CyberSaiyanIT/rhc22-badge repository.
The public badge page, image archive, and API point at a licensed upstream raster asset with source and attribution preserved.
The README names five designers and team sources name SemiTO-V and NextPCB, but reviewed sources do not allocate individual PCB, firmware, FPGA, artwork, review, procurement, assembly, quality-control, logistics, handoff, support, or image-rights roles among the named people or organizations.
The dossier credits named contributors and the stated production partner without inferring sole authorship, manufacture responsibility, fulfilment ownership, product-support duty, or image authority.
The project README states a CERN-OHL-W hardware license and names RISC-V International, NextPCB, GOWIN Semiconductor, and DeepComputing as sponsors, while team posts associate the badge with the summit. These claims do not by themselves show that event organizers owned the repository, issued the board as a standard credential, endorsed every current revision, or granted image-reuse permission.
The catalogue links the source-license and sponsorship context while keeping organizer ownership, attendee credential status, trademark/endorsement scope, physical-delivery responsibility, and image rights separate.
SemiTO-V said it planned to bring 25 boards to the Developer Zone workshop, then reported that a logistics issue prevented intended June 8 distribution and hoped for June 9 availability. Reviewed sources do not establish a final inventory, distribution date, ticket eligibility, recipient count, pickup process, shipment, replacement, refund, completed handoff, or a universal attendee allocation.
The catalogue does not turn a limited planned workshop allocation into proof that all 25 boards, all workshop participants, or all summit attendees received a badge.
MuHack Badge
note
No documentary photo or official upstream raster render of the original badge has been cleared for public reuse.
Hardware facts remain source-backed while the catalogue withholds the image until licensed original photos are curated.
No RISC-V Summit Europe 2026 FPGA Badge image is published because the current repository gallery render is associated with a later revised source tree rather than a confirmed physical summit unit, and the reviewed materials do not provide complete image-specific event-unit status, named attribution, source URL, license or explicit permission basis, and local processing provenance together.
The record remains source-backed and image-free rather than copying repository renders, team social media, event media, screenshots, logos, or approximate/generated imagery.
No RomHack Camp 2026 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.
No IHC 2018 1337 3310 WiFi 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
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.
The LeccoOnline post-event report strengthens the event-context source trail but does not provide a reusable badge image license, attribution basis, and processing provenance for catalogue publication.
The record keeps the already-cleared MIT repository badge photo and does not copy post-event article media as an event-floor replacement.
Final hardware, firmware, photos, author credits, delivery status, and CTF/badge integration details are not public in the current source set; the official participant FAQ says badge details are expected closer to the camp.
The compendium can track the announced badge and challenge without inventing components, delivery outcomes, controversy, or authorship before the event ships.
BadgESC{21} Badge
note
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.
The Lecco record is a European reuse of the 2025 Hackaday Supercon Communicator Badge rather than a newly designed Italy-only board.
The compendium keeps separate United States and Italy event records while preserving the shared hardware and firmware lineage.
Original media and software archive still incomplete.
The entry is sourceable, but image and deeper software details remain intentionally omitted until licensing and archive recovery improve.
The public event-associated material establishes physical boards/prototypes, while a later August Version 1.6 commit fixes design issues and changes silkscreen after the June summit. The reviewed sources do not map the current repository files, gallery render, or all listed fixes to a particular physical summit board.
Current open design sources are linked for research but are not represented as the definitive exact event-unit design, final production revision, or a factual image of every distributed unit.
BadgESC{21} Badge
note
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.
