Operational history
Issues & Camp Impact
WHY2025 Badge
critical
The badge was publicly flagged as a fire hazard when used with unprotected 18650 cells because short circuits around battery traces and holders could cause dangerous heating.
The warning shaped distribution, battery handling, user confidence, and the badge's public reputation.
WHY2025 Badge
major
Feedback says there was little badge hacking during camp compared with SHA2017 and MCH2022, partly due to late arrival, limited distribution, missing app-store workflow, LoRa limitations, and sparse documentation.
The badge's technical potential was hard to realize while the camp was happening.
WHY2025 Badge
major
A CTF participant reported receiving their badge only on the final day of camp, making it difficult to work on an embedded-device challenge during the event.
Badge-dependent embedded work became timing-constrained for at least one participant; this aligns with public feedback about late handout.
WHY2025 Badge
major
Public feedback describes late and limited distribution, long queues, poor communication, and not enough badges for all visitors.
Many attendees could not use the badge as a nametag or as a normal camp hacking object.
SHA2017 Badge
major
Niek Blankers' retrospective describes a production crunch with hundreds of PCB revisions, a first supplier that could not deliver, and a rapid PCBWay rescue to get boards made before camp.
SHA2017 is remembered as successful, but its production story still shows the logistics risk behind ambitious camp badges.
HackerHotel 2020 Badge
major
The documentation warned not to let the badge front contact metal because exposed ground and protruding battery terminals could short and overheat batteries.
Users were told to remove batteries when storing the badge and to handle the exposed front carefully.
WHY2025 Badge
major
Epoxy was applied as a last-minute mitigation, and the badge wiki later warned about reports of uncured epoxy.
Volunteers spent substantial camp time applying epoxy; users had handling and curing concerns.
WHY2025 Badge
major
Public sources document a Badge Team conflict before the event. Hackaday reported that the original Dutch badge team resigned en masse after disagreement with organizers; orga mailing-list posts confirm a conflict involving project leadership, a hardware lead, and others while cautioning that public facts were incomplete.
The conflict forms part of the badge's production history and likely contributed to a hurried replacement effort, but individual claims should not be overstated beyond public evidence.
CampZone 2020 Badge
moderate
The BadgePython API matrix lists CampZone 2020 with display support but without the generic buttons API, so portable apps expecting the standard buttons module need badge-specific input handling.
CampZone 2020 should be represented as a reusable Badge.Team firmware badge with a different input API surface, not as a drop-in match for every BadgePython app.
WHY2025 Badge
moderate
The LoRa connector was not pre-soldered, the supplied antenna was documented as a compromise 868/915 MHz antenna, and the wiki warned that transmitting without a connected or correctly matched antenna could permanently damage the Semtech SX1262 transmitter. The dedicated antenna page records VNA/SWR measurements, including one report above the safe SWR threshold at EU frequency before antenna rework; the compendium treats the colloquial bricked-antenna story as a source-backed RF-transmitter damage risk rather than as a literal claim that antennas themselves were bricked.
LoRa was not a simple out-of-box feature: users needed soldering, antenna choice or tuning, and caution with auto-transmitting firmware such as Meshtastic to avoid RF damage.
WHY2025 Badge
moderate
Issue reports include OTA stalls, blue screens, missing apps after reflashing, wrong USB-port confusion, SD-card boot problems, and settings-app failures.
Users needed post-event reflashing and troubleshooting before the badge became a stable hacking platform.
CampZone 2019 Badge
moderate
The docs describe the default firmware forcing an OTA update on the CampZone WiFi network before use, with a manual post-event flashing path for users outside the event network.
The first-use path depended on event infrastructure, while post-event users needed to follow a separate reflashing workflow.
HackerHotel 2019 Badge
moderate
The audio jack was mounted in reverse due to a design error, requiring the first and third rings to be swapped for correct stereo output.
Attendees needed a hardware fix for proper audio behavior.
HackerHotel 2020 Badge
moderate
The SAO connector was placed on the bottom instead of the top, mirroring the connector relative to the SAO specification; LED-matrix pinout problems also required bodgewire rework.
Users wanting add-ons or full LED intensity needed rework guidance and sometimes volunteer help.
SHA2017 Badge
moderate
The retrospective says the boards used 30 SK6805 RGB LEDs each and that the team manually placed roughly 105,000 LEDs using laser-cut mylar solder-paste stencils.
The badge's visual polish came with substantial volunteer assembly effort that belongs in the compendium's production history.
The troubleshooting section documented an unresponsive three-red-light state as EEPROM corruption and directed attendees to Badge.Team members for quick reprogramming.
The record captures both a failure mode and the on-site support workflow that kept the challenge playable.
MCH2022 Badge
note
FPGA development had a separate workflow from normal Hatchery apps, including examples, dedicated repositories, and a WebUSB loading path.
MCH2022 was accessible as a Python app badge, but its FPGA surface required a higher hardware-tooling skill level.
Konsool
note
Hackaday reported that Tanmatsu originated in Badge.Team and had been destined to become the WHY2025 badge before a significant disagreement between event orga and Badge.Team left it as a standalone project.
The record links the standalone Tanmatsu/Konsool platform to the same Dutch camp badge-history branch as WHY2025 without treating it as the shipped WHY2025 attendee badge.
Konsool
note
Tanmatsu has an active manual and manufacturer update trail, so specs, app behavior, and module support may continue to change after this seed record.
The compendium should revisit the platform periodically rather than treating this page as a frozen historical badge entry.
Badge.Team explicitly calls out fitting the LoRa, keyboard, big-screen, ESP32-P4 ambition into budget as the next challenge.
The final badge may differ from the early public ambition, so hardware claims should be revisited when production docs are published.
HIP97 Photo Badge
note
The surviving public pages name people who showed or preserved badges, but do not identify the original badge designer or registration-system implementers.
Credits should be updated only if primary sources or firsthand records identify the people behind the badge workflow.
The official page says registered conference attendees got the badge, while non-paying conference visitors could buy one on-site for EUR35 from an extremely limited supply.
The record distinguishes registered-attendee distribution from the free CommSec Village visitor purchase path.
The event archive proves an anniversary electronic badge and Badge Village, but does not expose attendee eligibility, public sale terms, or production quantity in this pass.
The record avoids implying universal attendee distribution or a known production run.
SHA2017 Badge
note
Key SHA2017 information is split across Badge.Team docs, the original SHA wiki, GitHub repositories, Hatchery, Hack42 WebUSB, talks, and retrospective posts.
The page should keep multiple source links instead of pretending there is one complete canonical source.
MCH2022 Badge
note
MCH2022 details are split across Badge.Team docs, Hatchery app pages, GitHub firmware repositories, and technical media coverage.
The compendium treats MCH2022 as a platform record with multiple source trails rather than a single static badge page.
SHA2017 Badge
note
The Gameboy emulator writeup highlights the challenge of adapting fast interactive graphics to an e-paper badge display.
This is useful lore for app-store records: the badge could run surprising software, but display technology shaped what was practical.
MCH2022 Badge
note
The expansion docs split Qwiic, SAO, PMOD, IR, GPIO, and debug surfaces into separate pinout records, which users needed to follow before attaching hardware.
The badge exposed rich expansion hardware, but safe use depended on reading the correct connector documentation.
The getting-started notes say USB-serial adapters and headphones were available only as needed, not in every badge bag.
The badge game depended on accessories that some attendees needed to borrow from the badge hacking area.
The Hackaday report is useful for attendee-facing behavior and lore, but detailed component claims should still be checked against the official Badge.Team hardware repositories and schematics.
The dossier can use the report for mesh gameplay and relay-interface lore while keeping low-level hardware claims anchored to primary sources.
The official archive confirms a special-edition electronic badge and Badge Village hacking path, but this pass did not recover component list, schematic, BOM, board files, exact chip, production count, or firmware repository.
The dossier records the verified anniversary-badge context while avoiding unsupported component-level claims.
CampZone 2019 Badge
note
The hardware-mod notes warn that full-brightness LEDs can overload the badge's capacitor when powered only over USB.
Users running LED-heavy apps needed to understand power limits and hardware context.
HIP97 Photo Badge
note
HIP97 belongs in the compendium as a badge-culture precursor rather than an electronic badge; the technical artifact was the improvised photo and printing pipeline.
Keeping this distinction prevents early Dutch camp history from being erased while avoiding false claims about hackable electronics.
GHP1989 is documented as the beginning of the Dutch hacker camp lineage, but no sourceable public record currently supports a specific electronic or hackable badge artifact.
The page keeps the origin point visible while marking the badge itself as an identity/pass record pending primary material recovery.
HEU1993 is part of the Dutch outdoor-camp sequence, but the public history table does not establish a firmware, PCB, or production badge record.
The compendium includes HEU1993 as lineage context and avoids claiming electronics until a primary artifact source appears.
HAL2001 Simple Badge
note
Public badge-history sources describe earlier Dutch camps such as HAL2001 as having very simple badges or none at all, and no sourceable public record currently supports an electronic HAL2001 badge specification.
The compendium includes HAL2001 as a lineage and identity-artifact entry while leaving electronics, credits, and images marked for primary-source recovery.
Public badge-history sources name What The Hack 2005 as part of the earlier simple/none badge era, before the later Dutch open-hardware badge expectation.
The page keeps WTH2005 visible in the Dutch lineage without falsely presenting it as a firmware or app-store badge.
HAR2009 is part of the Dutch outdoor-camp sequence, but the current public badge record does not establish a modern electronic badge comparable to SHA2017 or MCH2022.
The record is intentionally conservative until primary photos, registration notes, or production files identify a specific badge artifact.
OHM2013 sits immediately before SHA2017 in the Dutch camp lineage, but currently has stronger public memory as hat/patch identity culture than as a sourceable electronic badge.
The compendium models OHM2013 as a non-PCB identity artifact and leaves any electronic-badge claim open pending primary evidence.

The record remains source-backed and image-free rather than copying Badge.Team page media, documentation screenshots, event photos, placeholders, or generated approximations.
Badge.Team publishes useful official HackerHotel 2024 badge photos, but this pass did not find an explicit reusable content license for those documentation photos; the catalogue therefore withholds the image until reuse rights are cleared.
The image replacement queue can point contributors at the right source page without importing an all-rights-reserved-looking photo into the public archive.
No reusable original HackerHotel 2025 badge photo has been cleared in this pass, so the catalogue publishes the record without a badge image.
The image archive should stay empty for this badge until an original licensed photo can be attributed and processed.

MCH2022 Badge
note
The badge combined ESP32, RP2040, and iCE40 software stacks, each with its own repository or workflow.
The architecture enabled unusual experiments but makes firmware provenance and troubleshooting more complex than a single-MCU badge.
Konsool
note
Konsool/Tanmatsu is an ongoing open-design handheld platform, not a single event badge with one fixed camp context.
badge.gallery models it separately from event editions so add-ons, apps, and firmware can continue evolving without rewriting a historical event page.
The public record currently names ambitions and project phases, but not a final schematic, firmware repository, app ecosystem, issue history, or shipped badge.
badge.gallery should track the planned badge without overstating it as a delivered artifact.
Konsool
note
Konsool exposes LoRa regional settings, so users need to configure frequencies and regions appropriately rather than treating radio as a universal default.
The platform needs region-aware documentation and defaults for legal and reliable LoRa use.
Konsool
note
The manufacturer update discusses CE, UKCA, and FCC documentation work as part of moving from hacker-platform design toward wider distribution.
This is useful operational context for an open badge-derived platform becoming a purchasable handheld.
HITB stated that the badge hardware, software, and firmware were fully open sourced, but this pass did not recover a stable repository or downloadable source archive URL.
The dossier records the public hardware-spec and challenge surface while avoiding unsupported firmware, schematic, or implementation claims beyond the official page.
The badge was a reused e-paper price tag rather than a custom conference PCB.
The compendium treats it as a badge-hacking object and post-event firmware target while avoiding unsupported claims about custom hardware design.
Public details found in this pass describe the e-paper tag workflow but not a complete bill of materials, radio protocol teardown, or production team list.
Future work should add chip-level tag models, packet captures, firmware forks, and attendee writeups if they are published.
The public talk anchors the badge-team workflow and lessons learned, but this pass has not recovered a durable hardware BOM, schematic, firmware repository, app-store entries, or complete author list.
The dossier preserves the public badge talk while avoiding unsupported component-level claims.
SHA2017 Badge
note
The WebUSB install path depended on browser USB support and a hosted installer, which made setup easier for supported environments but added platform and link-lifecycle dependencies.
The install workflow was accessible for many users, but the compendium records it as an ecosystem dependency rather than firmware alone.
