BSides Fort Wayne 2026 Optional E-Badge
Optional organizer e-badge ticket add-on paired with a distinct 2026 source archive
BSides Fort Wayne's organizer ticket page offered a $30 optional e-badge add-on for the June 6, 2026 conference. The public BSidesFW2026Badge repository has distinct June 2026 activity, including a dedicated STLs/2026 enclosure set and default badge data changed to 2026, together with MicroPython source and inherited V4 technical documentation. The evidence links a real optional e-badge offer to a 2026 source archive without claiming a confirmed sale, physical receipt, firmware deployment, or exact final hardware configuration.
BSides SP 2026 Garoa Badge REV. 0
Garoa ESP8266/OLED community electronic badge
Garoa Hacker Clube's own event-period demo repository identifies its REV. 0 board as a badge distributed at BSides SP 2026. The Garoa and official V21 event sources establish the completed São Paulo conference, while the public source trail documents an ESP8266 badge with a 128×64 OLED, buttons, sound/IR path, microSD socket, FTDI programming header, and public KiCad/Gerber/BOM material. It does not prove one final firmware or hardware revision for every conference unit.

Cyb3rBytes404 Cyber-Cat Badge (DEF CON 34)
Small-batch pre-event RP2040 youth-coding giveaway badge for DEF CON 34
A late-July public r/Defcon post by u/ProfessionalPea2218 says its author has been designing and hand-soldering a small batch of badge PCBs to help launch Cyb3rBytes404, a self-described San Diego nonprofit for free hands-on youth coding and electronics projects. The author says the badges are not for sale and are intended for random giveaway throughout ‘the con.’ Separately, the public Cyb3rBytes404 GitHub repository calls itself the official repository for the cyber coding camp and documents a custom RP2040 cyber-cat badge, MicroPython starter material and challenges, an MPU-6050 motion module, and thirty WS2812 RGB LEDs. Its visible commit history places the reviewed README update on July 28, 2026. The shared project name supports a source-backed pre-event DEF CON 34 association, but it does not establish that the Reddit author controls the GitHub namespace, that every physical PCB matches the repository snapshot, final hardware, the run size, a completed giveaway, or a DEF CON-issued credential.
DEF CON 34 Silent Disco Badge
Maker-published physical silent-disco badge; organizer role and handoff unverified
LastZactionHero's public repository is titled DEF CON Silent Disco Badge and documents a wearable electronic badge that plays local DJ mixes, drives a music-linked light show, and syncs badge-to-badge over infrared. Its August 4 maintainer update says the boards were fabricated, assembled, and playing music, and that every badge's QR silkscreen points to the repository. The public archive contains KiCad design and fabrication material, firmware, and a MIT license, sufficient to record a distinct maker-published physical DEF CON 34-associated artifact. No reviewed DEF CON, venue, silent-disco organizer, sales, or handoff source establishes official issuance, a run size, recipient allocation, or completed event distribution.
DEFCON Furs 2026 Badge
Sold-out RP2040, LoRa, NFC, and LED community-event badge preorder
DEFCON Furs' official 2026 site and Hack Your Lives donation-store listing identify a distinct 2026 #badgelife badge for the DEF CON 34 period. The currently sold-out listing describes an assembled badge plus a blank PCB, an RP2040, LoRa radio, NFC, 48 RGB LEDs, MicroPython, touch points, and an SAO 1.69bis interface. It says paid orders will be assembled and shipped by September 30, while blanks were offered for in-person DEF CON pickup. Those are organizer-published preorder and planned-fulfillment statements, not proof that every order shipped, that each unit has the described final configuration, or that a specific recipient collected one.
Disobey 2026 Badge
ESP32-S3 MicroPython game badge
A Finnish Disobey badge built around ESP32-S3, a 1.9-inch TFT display, SK6812MINI RGB LEDs, joystick/buttons, MicroPython game firmware, OTA setup, web flashing, badge competitions, and a public hardware/firmware repository.
EMF 2026 Spaceagon Badge
Released Tildagon frontboard revision with reusable base and new input surface
Spaceagon is the released 2026 update to EMF's reusable Tildagon badge platform. The official completed-event, order, assembly, and API pages document a complete kit or a 2024 upgrade path, the new Spaceagon frontboard, and a distinct input surface while retaining the Tildagon base and hexpansion ecosystem.
Gothcon 2026 Blinky Badge
Pre-event ESP32-C3 bat-shaped LED party-fundraiser badge
Gothcon's official badge store describes a custom bat-shaped PCB LED badge for the free Gothcon dance party at DEF CON 34. The $80 fundraiser package names 44 independently controlled RGB LEDs, a 2,000 mAh Li-Po battery, USB-C recharging with overcharge protection, a removable laser-etched acrylic shield, a custom lanyard, and an ESP32-C3 with 4 MB flash. The public `claviger/gothcon-firmware` repository adds MicroPython firmware, KiCad schematic/PCB/Gerber material, GPIO mapping, pattern/palette controls, and ESP-NOW badge-to-badge contagion. The store explicitly says its SAO connectors are mirrored and not functional with a standard SAO. Pre-orders are closed and the store says badges will be sold at DEF CON; this remains a pre-event party-fundraiser record, not proof of final sales, delivery, party outcome, or official DEF CON credential status.
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.
Kernelcon 2026 Off Grid Badge
ESP32 weather and crank-powered quest badge
Kernelcon's 2026 Off Grid badge is an ESP32 weather-prediction and quest badge with BME280 temperature, humidity, and pressure sensing, twenty addressable RGB LEDs, AAA and hand-crank power modes, BLE/proximity scanning, and MicroPython firmware.
Overglade 2026 Zero-Power NFC E-Ink Badge
Maker-documented RP2040 e-ink/NFC game-jam badge
Kai Pereira's public archive identifies these as Overglade hackathon badges designed for the completed Singapore game jam. The device has an RP2040, passive NFC, an onboard e-ink driver, and an exposed ticket-shaped PCB with public KiCad and MicroPython source trees. Official Hack Club pages establish the event, but not a badge entitlement or all-recipient allocation.
Temporal Replay 2026 Badge
MIT-licensed ESP32-S3 badge with Doom, MicroPython, and IR boop
An official Temporal Replay 2026 developer-conference badge documented by the MIT-licensed temporal-community/badge.temporal.io repository as an ESP32-S3 app platform with an OLED and LED matrix, a Doom port, MicroPython, and infrared boop badge-to-badge networking, for the May 5-7, 2026 event in San Francisco.
Workday DevCon 2026 Blinky 2350 Badge
Post-event Pimoroni Blinky 2350 developer-conference badge; organizer allocation unverified
A public post-event app archive by Mainak Sarkar identifies a Pimoroni Blinky 2350 badge as handed out at Workday DevCon 2026 and says it ran the badgeware MicroPython operating system and app launcher. Workday's official pages establish the completed June 1-4 Las Vegas developer conference, but do not directly document badge issuance, recipient allocation, custom hardware, event firmware, or image rights. This is therefore a source-backed event badge record with intentionally limited organizer attribution.
