Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The writeup explicitly planned to make badges a mainstay at future AfricaHackOn conferences, move from about 20 selected units to all attendees, and transition to a professional PCB.
SourceCisco Connected Mobile Experiences data supplied the venue-location context used to personalize badge behavior and analyze attendee movement.
SourceNodeWatch and NearForm document TensorFlow Lite for Microcontrollers experiments for gesture recognition on the watch, with a public model notebook and application examples.
SourceParticipants trained the cars' neural networks by manually driving around the track before testing autonomous driving behavior.
SourceThe miniconf workflow gathered training video from the car and analyzed it offline with TensorFlow before attendees tried self-driving runs.
SourceOfficial docs preserve post-event recovery behavior: firmware v1.6.0+ can force hexpansion detection with button chords, and failed updates may require better WiFi or flashing.
SourceThe DEF CON 27 bio describes TwinkleTwinkie as an independent PCB artist who has manufactured artistic PCB badges and indie badge add-ons.
SourceThe releases page preserves Prototype 3 BOM/CPL/Gerber/schematic assets plus summit_v1 and summit_v2 firmware and filesystem release files.
SourceThe PCB repository preserves Eagle board and schematic files, a project library, scripts, OSH Park design rules, and multiple Gerber ZIP archives.
SourceBadge Pirates publishes CC13 Gerbers, KiCad sources, documentation outputs, and an MIT repository license.
SourceBadge Pirates publishes Gerbers, BOM exports, an interactive BOM, ESP32-S3 reference material, and BasicCodeForQA for the CactusCon 12 badge.
SourceThe repository README documents compressing the production files and using the centroid and BOM files to order boards through JLCPCB.
SourceThe repository preserves the Multnomah KiCad PCB, schematic, project, netlist, footprint table, symbol table, and local footprint directory.
SourceThe repository preserves BSidesPDX_2018 KiCad board, schematic, project, libraries, local footprints, and Gerber/drill outputs.
SourceThe repository preserves OpenTaxus KiCad schematic, board, project, footprints, logos, and dock files for hardware review and reproduction.
SourceBadge Pirates publishes KiCad files, schematic PDF, interactive BOM, Gerbers, STEP exports, and STL/3MF enclosure parts for manufacturing and review.
SourceThe official write-up says the badge shells were printed on one Prusa MK4 over about a month and a half with full-plate front/back batches.
SourceThe build story and Hackaday article call out a clothespin-based programming jig as part of the practical production workaround trail.
SourcePublic sources document ICSP programming with pogo pins and a clothespin pogo-clamp workflow used during badge production.
SourceOSHWA and repository documentation describe CAN 2.0B/NMEA-2000, NMEA-0183, and Modbus RTU transceiver modes with software-controlled half- and full-duplex behavior.
SourceThe badge page lists the included wildflower seed mixture and asks attendees who are not based in New Zealand to return the badge in merch-desk recycling boxes.
SourceThe README describes ADC streaming over a serial interface and frames the badge as a basic 12-bit logic analyser for low-rate signal inspection.
SourceThe wiki tracks 3D-printed cases, spacers, covers, and repair guidance, reflecting the post-event mechanical support ecosystem.
SourceThe official badge page links 3D-printable mechanical accessories and CAD resources for carrying, controlling, and decorating the badge.
SourceThe artifact consisted of a white baseplate PCB and a separate USB-stick badge board, with soldering-pad access for serial-adapter bootloader repair.
SourceHackaday describes the badge as a cube constructed from PCBs soldered along their edges, with a run of over 400 units assembled by hand.
SourceHackaday's customization article points attendees to STEP, DXF, and SVG front-panel models so the non-electrical front PCB can be replaced with CNC, laser-cut, or 3D-printed panels.
SourceHackaday's customization article frames the badge as built to be modified with replaceable front-panel mechanical files.
SourceThe 3D-print README documents soft flexible and hard hinged bangle shells for holding the electronics, with magnets, hinge wire, and heat-shrink retention.
SourceThe production path moved from a two-material ABS and PC enclosure concept to a single clear polycarbonate housing so the PCB color and LED passthrough could work within the tooling schedule.
SourceThe same Hackaday.io log identifies the enclosure as an injection-molded rocket shell and credits Jaycon Systems for the production path.
SourceThe Ph0xx logs document 4.2 mm holes on an 8 mm grid so the badge could mount into LEGO Technic-compatible builds.
SourceNathan Dumont's Omni wheel appears in the official showcase with published files, another example of Tildagon add-ons using mechanical play rather than only electronics.
SourceThe badge's mechanical identity comes from turning old Nokia 3310 phone shells into camp badge enclosures while keeping the keypad and handheld form factor.
SourceThe public repository includes 3d_Prints model/STL material and a Project-CC13 STEP export for mechanical reference.
SourceThe Hack-Master badge used a dual-PCB assembly and two RGB LEDs as backlights for a custom image reel.
SourceThe back-cover README documents printable cover and switch-cap files, optional additional LEDs, switched-power pickup pins, LED mounting, masking, and snap-on assembly.
SourceNathan Dumont's Flopagon uses a floppy-disk form factor, documenting that Tildagon add-ons range beyond simple sensors into playful media and mechanical experiments.
SourceFolded liner notes and the cassette audio carried track-list, color, character, tone, and number-station-style clues for remote badge solving.
SourceThe official media page points to a main showcase video and making-of material for the ConfiBadge 2026.
SourceThe badge splits flash into code and filesystem partitions and exposes a USB mass-storage volume where users copy 128x160 TGA images into `blingpic/` for display on the badge.
SourceThe official home page says the badge bundle contained a CarolinaCon T-shirt, shot glass, sticker, and Conference PCB Badge.
SourceThe official page says the merch bundle included a kit with all parts needed to make the year's badge.
SourceThe badge ships with the LHC channel preprogrammed, while the LHC guide documents QR-code onboarding and Meshtastic channel setup.
SourceThe README identifies ATTiny85 / ATTiny45/85 Optiboot as the badge controller target and documents Arduino IDE / ATTinyCore setup.
SourceThe same source identifies the controller as an ATtiny84 and warns that incorrect orientation leaves the badge non-functional.
SourceThe repository production CSV identifies the V2.2 badge controller as an STM32F103CBT6 in an LQFP-48 package.
SourceThe hardware writeup and repository document the badge around an ESP8266 module with USB serial programming and Wi-Fi features.
