Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The README calls for VS Code, Python, mpremote, and a boot-select flash procedure, using a Raspberry Pi Pico 2 on a breadboard for current firmware development rather than documenting a final deployed attendee workflow.
SourceThe public README documents building a Posix-style SDL simulator for app development and debugging on a computer before flashing badge hardware.
SourceThe Cryptocurrency Village workbook lists feature, simulator, and development workshops for the badge, including an ESP-IDF toolchain workflow and USB Type-C cable requirement.
SourceJonTheNiceGuy's WiFi Scanner app scans nearby access points and includes a connection doctor that decodes STAT_* failures, a practical post-event network-debugging upgrade.
Sourcewebboggles' Tildagon WiFi Radar turns a single badge into a directional WiFi radar: rotate the badge to sweep and nearby APs appear as blips on a polar display.

SourceThe public event guide describes an 8×16 RGB LED matrix and five physical buttons on the wearable game-console badge, while the event source targets a CH32V003 board.
SourceThe JLCPCB BOM lists 128 LED designators for the matrix and eight TL3301-style tactile switches, matching the firmware row/column refresh and button-scan notes.
SourceThe retrospective documents the 220x176 LCD upgrade, 40 MHz SPI and SD-card behavior, double-buffered display goals, and reduced frame-rate decisions caused by SD-card constraints.
SourceProject details describe a 2.2 or 2.4-inch DMA-driven SPI TFT display with ILI9341/45 support and SPI SD card storage.
SourceThe design uses an IS31FL3741 LED driver IC to drive the LED matrix, with related schematic and PCB material in the hardware archive.
SourceThe release firmware includes PCD8544/Nokia LCD initialization, cursor movement, character printing, contrast, and image drawing paths.
SourceThe organizer-linked design documents a 24-pin J4 socket for e-paper or TFT SPI display modules, with GPIO, reset, busy, data-command, chip-select, clock, and MOSI details.
SourceThe public README documents a 9×9 IS31FL3731 charlieplexed LED matrix and four front LEDs as the badge's visible interaction surface.
Sourcedratini0's HUB75 hexpansion ties the badge platform to large LED-matrix display experiments through published hardware files.
SourceThe party loop displays the BLE banner, flips display inversion, and periodically chooses random scroll directions.
SourceThe hardware documentation maps two SPI screen headers with separate DC, reset, chip-select, and display-enable control signals.
SourceThe main schematic includes a GC9A01 IPS SPI display, while the firmware README describes user-customizable 240x240 JPG/GIF badge images.
SourceThe firmware and hardware trail document a Nokia 5110-style PCD8544 LCD as the badge display surface.
SourceThe README requires SSD1306 128x64 configuration, and the firmware initializes an Adafruit_SSD1306 display at I2C address 0x3C.
Sourcekliment's Flipspansion is an adapter for mounting a hexpansion upside down, with caveats around USB-port-adjacent slots preserved in its project notes.
SourceThe badge page states that only 50 units were available, shipping was not offered, and pickup was at DEF CON 33 with possible in-person sales if any were left.
SourceThe official page says limited BIC Picks were available at DEF CON 33 through direct inquiry, limited purchase, or trade.
SourceThe README says the badge was sold at the Hacker Warehouse vendor booth during DEF CON 33 and that half of profits went to the Tor project.
SourceSomerset Recon's README says 400 badges were distributed at BSides San Diego 2024 and describes a wireless Bluetooth LE rock-paper-scissors game. The count is a source-archive claim, not a recipient ledger or proof that every attendee had an identical unit.
SourceThe source describes flashing about 120 cartridges for the H2HC 2023 Game Boy badge/game artifact.
SourceThe official badge page says short lead times limited the assembled run to about 200 badges, while attendees who did not sign up for the assembled option still received a PCB.
