Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The wrap-up says participants attended soldering sessions and soldered their badges to make them light up.
SourceThe official page says the badge was also a DIY soldering project, with setup in the Student track / Village from check-in through the event.
SourceThe preorder kit included solderable LEDs/resistors and SMA connector work, plus badge PCB, antenna, encoder, and screen.
SourceleLAB identifies Badge Hackropole soldering as an introductory activity with no technical prerequisite; workshop sign-up was on site, first come first served, and groups were limited to ten people maximum.
Sourcewalkerdanny's Caffeine Jitters is a companion app for the Club Mate haptics hexpansion, where badge buttons adjust jitter frequency.
SourceBadge.Team preserved MicroPython examples for outline RGB LEDs, buttons, power saving, buzzer tones, screen rotation, raw touch reads, and virtual timers; the hardware also exposed infrared transmit and receive.
SourceThe official challenge asked participants to assemble the collector badge, analyze its embedded secure system, and solve first for a Nuit du Hack Black Badge life pass.
SourceTilde Industries produced a CYBER SCARAB add-on for the HackerHotel 2020 challenge badge.
SourceJeff and Jann Foehringer designed the Fuccs add-on, with the PCB layout published in its own repository.
SourceLoRa use depended on attaching the connector and a suitable, matched antenna; the wiki records VNA/SWR antenna checks and warns that transmitting without a proper antenna could permanently damage RF hardware.
SourceParticipant reporting says CTF success yielded cool add-ons for the Easterhegg badge and that the badge could later be soldered in the hackerspace.
SourceThe separate tr23-sao-hw repository documents a companion SAO board for the TROOPERS23 badge.
SourceThe repository documents an SAO connector on the badge for add-on expansion.
SourceThe official page documents a BOSS socket so the badge can be extended with add-on boards.
SourceThe breakoutboards branch collected accessory board designs and parts information for the 2018 badge.
SourceKonsool documents expansion boards and multiple expansion buses, making external hardware part of the platform rather than a one-off mod.
SourceSix edge connectors allow community hardware modules such as prototyping boards, decorative boards, sensors, GPS, communications, plotter experiments, and other hexpansions.
SourceThe Ph0xx project documents jewel add-ons as part of the intended hardware play surface.
SourceThe r0ket wiki tracked hardware hacks, shields, and add-on ideas, making expansion hardware part of the badge culture from the start.
SourceThe TROOPERS19 badge exposed a 3.3 V I2C Shitty Addon interface so the badge could wear its own small add-on boards.
SourceThe hardware repository visibly contains KiCad board/schematic/project material, BOM/position files, front/back/order Gerbers, and acrylic directories/files. The published tree is traceability evidence, but this pass did not reconcile it to a final 2026 populated board, fabrication order, component sourcing, acrylic process, assembly/test procedure, host connector/power design, or explicit license.
SourceThe reviewed snapshot preserves KiCad PCB/schematic material and Arduino-style physical-badge source. Its post-event publication does not prove an exact deployed revision or source-to-device mapping.
SourceThe reviewed snapshot preserves KiCad, Gerber, BOM, and Arduino-style source material. The README says conference badges used earlier firmware than later source behavior, so the archive is not treated as an exact event-day deployment image.
SourceExternal ICSP, RX, TX, and reset access made reflashing and serial extension possible, while special RF codes could store text in EEPROM or trigger visual effects.
SourceThe badge README documents an ESP32 Wi-Fi module running MicroPython, and the repository preserves the source tree and binary image used to operate the badge.
SourceThe maker lists an ESP32, USB-C, rechargeable Li-Po, ten LEDs, a screen, and one button. It describes short presses as scrolling and long presses as selecting, but does not publish component variants, circuitry, pinout, power details, or electrical documentation.
SourceThe attendee writeup describes the 2024 badge as an orc-shaped electronic badge using a 555 timer, LEDs, diode, resistor, capacitor, and 9V battery power.
SourceThe badge used a Watterott Wattuino Nanite 85 / ATTiny85 USB-stick style board to act as a programmable USB keyboard injector.
SourceThe BOM lists an ATTINY85-20SUR microcontroller and the Eagle schematic instantiates U1 as a Tiny85-20-SMT device.
SourceThe firmware README describes the badge as ATTiny861-based, and the BOM lists an ATTINY861A-XUR / ATTINY861-class SOIC-20 controller.
SourceThe A Nice Edit walkthrough identifies ATmega1284P processors and an FTDI serial converter chip used to provide USB serial access to the badge.
SourceThe official parts list centers the badge on an AT-MEGA328P-PU, eight 5mm LEDs, two push buttons, 16 MHz crystal, passives, socket, and coin-cell power.
SourceThe badge used an ATmega32u4 with four RGB NeoPixels, three potentiometers, micro USB, and two CR2032 holders.
SourceHackaday and the build guide identify the reverse-side microcontroller as an ATtiny841 / ATTINY841-SSU.
SourceThe repository BOM lists an ATtiny85-20SUR microcontroller and 24 blue side-view LEDs as the badge's main active components.
SourceTechGirlMN's hardware guide centers the remote badge build on an Arduino Nano mounted to a solderable breadboard-style PCB.
SourceThe README describes the BSidesPDX mask modification as using an Arduino Pro Micro-class board with ATmega32U4 and USB Micro instead of the original Arduino Nano approach.
SourceThe project page and postmortem document a Rigado BMD-300 module based on Nordic nRF52 with ARM Cortex-M4F, 512 KB flash, 64 KB RAM, integrated antenna, Nordic S132 SoftDevice, TFT display, WS2812B LEDs, sensors, and microSD.
SourceThe repository BOM lists a BMD-300 module and the Eagle schematic exposes the Nordic/BMD-300 pinout, SWD pins, NFC pins, and power connections.
