Seeded artifacts
Buenos Aires speaker VIP identity badge
A conservative NotPinkCon 2019 record for the VIP badge listed as a speaker benefit in the conference CFP, tied to the Buenos Aires women-led information-security conference rather than an electronic badge lineage.
Official role and competition badge-art variants
A conservative Ekoparty 2021 record for the official badge-artwork set preserved on Ekoparty's own site, covering attendee, speaker, workshop, ACFT first/second/third-place, ICFT player, and Lado B variants.
First limited electronic EKO badge offer
A conservative Ekoparty 2023 record for the first limited electronic badge offer, capped at 500 units and used as a paid support option for a free Buenos Aires hacker conference.
ESP32-C6 LoRa badge
The official Ekoparty 2024 electronic badge documented by Electronic Cats with ESP32-C6 control, RFM95 LoRa radio, OLED display, NeoPixels, USB, buzzer, KiCad hardware files, firmware sources, Badge Connect behavior, and a community Meshtastic variant trail.
Artistic sonic RP2040 badge
An official Ekoparty 2025 electronic badge record for a customizable artistic and sonic badge with RP2040 control, I2S DAC audio, headphone and speaker amplification, rechargeable USB-C power, NeoPixel backlight LEDs, resistive touch sensors, sequencer, sample playback, synth behavior, and effects.
Champion-tier nRF52840 LoRa Meshtastic badge
The Ekoparty 2026 electronic badge, included with the Champion ticket tier while supplies last. On October 3, 2026, four days before the October 7-9 Buenos Aires conference, badge-team member Nicolas Restbergs (Fábrica Marciana) published the ekoparty-badge-2026 repository, which calls itself the firmware for the official Ekoparty 2026 badge: a Meshtastic node on an nRF52840 with an SX1262 LoRa radio, a 0.96-inch OLED, Bluetooth pairing with the Meshtastic phone app, a piezo buzzer, six rear SK6812 backlight pixels, and a separate status pixel. The release v1.0.3 adds a schematic, pin map, user manual, and the EKOBOOT bootloader image; v1.0.4 followed on October 5, and an EasyEDA Pro project and a low-temperature-solder fragility warning were added on October 8, during the conference. By October 9, 2026 Ekoparty's own event page carried an EKO BADGE ELECTRÓNICO section describing the badge as a customized Meshtastic build that works off-grid and links to the badge team's guide, and an October 12 attendee writeup confirms the event took place with Meshtastic Eko Badges in hand. Production count and allocation stay unconfirmed.
Events
The August 30, 2019 Buenos Aires information-security conference whose CFP preserved a speaker VIP badge benefit while making no public electronic-badge claim.
The 2021 Ekoparty edition represented by official Ekoparty media attachments titled as 2021 badge artwork for attendee, speaker, workshop, ACFT placement, ICFT player, and Lado B variants.
The Buenos Aires Ekoparty edition that publicly introduced a limited electronic badge offer of 500 units alongside free conference registration.
The November 13-15, 2024 Buenos Aires Ekoparty edition whose official event page documents the free CEC event and whose public Electronic Cats repository preserves the official electronic badge hardware and firmware.
The 21st Ekoparty Buenos Aires edition whose official badge page documents an artistic, sonic, customizable electronic badge with public hardware and firmware repository.
The planned October 7-9, 2026 EKO 22 Buenos Aires edition at CEC, where the current Champion ticket offer includes an electronic badge while supplies last but public sources do not yet document shipped badge hardware. A September 28 recheck found the full main-track agenda published with still no badge mention or reveal on the official event page. On October 3, 2026, badge-team member Nicolas Restbergs published the badge firmware, schematic, and manual as marsfactory/ekoparty-badge-2026: an nRF52840 and SX1262 Meshtastic node with OLED and RGB backlights. Firmware v1.0.4 followed on October 5, and on October 8 the badge team added an EasyEDA Pro project and a warning that the badges were assembled with low-temperature solder. An October 12 attendee writeup confirms the conference took place with Meshtastic Eko Badges. By October 9 the official event page had added an EKO BADGE ELECTRÓNICO section linking the badge team's guide, but on October 21 it still read pre-event with no wrap-up, so the edition is not yet marked completed.
Lifecycle
A long press on the Ekoparty frame opens a menu with five idle animations matched by rear backlight patterns, backlight brightness, manual QR visibility, status-LED filters, a bilingual credits screen, intro replay, and a reset of these preferences only.
A separately published bootloader derived from the Adafruit nRF52 bootloader. Holding the DFU button at power-on opens an EKOBOOT USB drive for UF2 firmware updates; a HEX image is used for the first SWD flash.
The community Meshtastic guide maps the badge to a PlatformIO ekoBadge environment with RFM95, OLED, three NeoPixels, keyboard buttons, and speaker pins.
Official attachment pages preserve first, second, and third-place ACFT badge-art variants for the 2021 set.
The ICFT player OP2 attachment page preserves a distinct ICFT player badge-art variant in the 2021 set.
Ekoparty sold a limited 500-unit electronic badge as a paid support option while preserving free entry for the 2023 Buenos Aires conference.
Ekoparty's official page identifies EKO 22 as the October 7-9, 2026 CEC Buenos Aires conference, and an October 12 attendee writeup confirms it took place; this is event context, not a completed badge-delivery record.
The firmware source tree includes LoRa manager, Llamaneitor, sounds, village modules, and Badge Link screens around the Ekoparty badge experience.
The firmware includes Badge Connect code for discovering nearby badges, storing badge MAC and type data, and showing cross-event badge findings for BSides, DragonJAR, EkoParty, and BugCON lineages.
The repository documents RAW mono 22050 Hz sample export, Python raw-to-header conversion, AMY sample-bank configuration, UF2 flashing, and alternate synth-drum firmware.
The developer guide documents cloning the badge repository, initializing submodules, using ESP-IDF, setting MININO_PATH, building Minino firmware from the eko branch, flashing, monitoring, and creating release builds.
Electronic Cats documents an ESP32-C6 badge platform with RFM95 LoRa radio, OLED display, NeoPixel LEDs, USB, buzzer, KiCad files, and 3D assets.
Four PCB-integrated resistive touch sensors control sample triggering, sequencer behavior, pitch shifting, and filtering through RP2040 ADC readings.
The current organizer-linked ticket page says the Champion tier includes an electronic badge for Ekoparty Buenos Aires 2026.
The badge runs as a Meshtastic client node on the SX1262 radio, pairs with the official Meshtastic phone app over Bluetooth using a PIN shown on the OLED, and sends and receives broadcast and direct messages without internet or cellular service.
Ekoparty's official attachment pages preserve attendee, speaker, and workshop badge-art variants for the 2021 set.
The CFP lists a VIP badge as part of the NotPinkCon speaker benefits package, alongside travel, accommodation, dinner, and parties.
The Lado B attachment page preserves a separate special badge-art variant in the 2021 set.
Operational history
The entry is modeled as official role and competition badge artwork instead of being upgraded into an unsupported hardware badge.
The record remains useful as a badge-art lineage entry while leaving event logistics and artifact distribution open for archive recovery.
The safety note belongs in the record because it affects handling of the physical artifact.
The record can document Badge Connect behavior and cross-event lineage while keeping firmware-configuration claims conservative.
The record describes the published design and firmware as badge-team evidence, now linked from the official event page, and keeps fabrication quantity and the link to the Champion allocation open until Ekoparty or further post-event sources confirm them.
The entry intentionally avoids component-level claims until primary technical documentation is recovered.
The catalogue models the item as a narrow speaker identity artifact and avoids unsupported hardware claims.
The South American entry now has a rights-cleared official upstream raster with source URL, license, attribution, and processing notes while avoiding generated or placeholder imagery.
The South American entry now has a rights-cleared official upstream render with source URL, license, attribution, and processing notes while avoiding generated or placeholder imagery.
Owners should handle and store the badge gently; component loss after a drop is a known risk rather than a defect of an individual unit.
The record remains source-backed and image-free rather than inventing a speaker badge image or copying event/social media.
The record links to the official sources while avoiding local copies of uncleared event media or generated substitutes.
The planned Argentine record remains source-backed and image-free rather than copying ticket artwork, event media, social-media photos, screenshots, placeholders, or generated approximations.
The record ships without imagery rather than using a social-media image, generated image, or uncleared event asset.
The record treats the badge as a real event artifact without asserting attendee-wide or Champion-wide delivery, and the edition is not marked completed until Ekoparty publishes post-event evidence.
The record still prefers a future licensed original documentary photo if one appears, but the current image is source-backed upstream material rather than generated, approximate, social-media, or placeholder art.
