SourceThe official page frames the BIC Pick as a red, green, and gold Afro-pick-shaped badge celebrating BIC Village's five-year anniversary.
SourceThe field report calls out an onboard relay whose practical purpose was tactile clicking, reinforcing the telegraph feel of the five-switch interface.
SourceThe pinout page lists button GPIOs, OLED I2C pins, I2S/audio labels, and userport GPIOs for badge hacking, with the exact table kept as documentation rather than a schematic or PCB archive.
SourceThe public plan sketches badge stations for hardware hacking, puzzles, games, a photo booth, or similar event-specific interactions.
SourceThe project-owner plan calls out UART or wireless communication so stations can update badge state or behavior without reflashing a full image.
SourceThe next-version plan keeps the self-service update-station idea that was not fully reliable enough for PN26 field deployment.
SourceThe PN26 writeup lists EEPROM storage for image data as the first improvement target for the next version, avoiding PN26's full-firmware-patch workflow.

SourceThe March 2025 update tracks firmware, app, documentation, module redesign, and production work, showing the platform evolving like a badge ecosystem rather than a static product page.
SourceThe brochure promoted a HIDIOT Hackster project-submission path with a prize for the best attendee project.
SourceSprite_tm documented adapting a Gameboy emulator to the SHA2017 badge's e-paper display, preserving a concrete example of post-camp app hacking under unusual display constraints.
SourceAfter camp, the badge could function as a small Arduino-like development board, keeping the badge useful for learning and experiments beyond the event.
SourceThe 28C3 update promised an improved mesh network, l0dables for interactive installations, and support for the next flame generation.
SourceThe Hackplayers recap links the first three winner write-ups and summarizes their approaches: firmware extraction, RISC-V reversing, logical-flaw exploitation, static and dynamic analysis, validation weaknesses, and state manipulation.
SourceAfter AC9, the official badge page published four booth/village unlock codes for people who missed them during the event.
SourceHardwear.io documents leaving the badge's presentation mode around the 6:30 mark and uploading pictures afterward, turning the attendee object into a reusable e-paper display target.
SourceBadge.Team published a post-event guide for completing the mixed-reality challenge without the original hotel props, magnetic maze, and badge-to-badge team formation.
SourceMarc Merlin's writeup and repository document Arduino-environment support for many IoTuz peripherals, demo code, calibration work, and board bring-up fixes.
SourceThe Europe CFP says attendees could reflash the badge after Hackaday Europe and use it as a Meshtastic device.
SourceThe official page links a post-event experiment for controlling extra addressable LEDs from the badge through WLED-style firmware work.
SourceCyber Saiyan reused the RHC22 badge as a MOCA 2024 workshop and contest target, publishing a dedicated firmware branch and inviting owners to bring the badge, a PC, and USB cable.
SourceElectrolama describes flashing Tasmota by default so the badge could continue as a room sensor after camp when paired with an external sensor.
SourceRepository sketches include production-test, serial-sensor, and MQTT sensor firmware; Marc Merlin's writeup adds a participant LED-strip blinky reuse trail.
SourceThe wrap-up describes the badge as capable of doubling as a breadboard after the event.
SourceAt 37C3, Hardware Hacking Area mentors provided HiP badges to teams for embedded-programming practice and allowed the devices to be taken home after the showcase.
SourceThe manual provides a post-conference conversion path for turning the badge into a RetroPie device after the event.
SourceThe post-event WiFi guide documents how owners can attach the badge to a home or workshop network after the camp infrastructure is gone.
SourceThe 2021 evolution talk documents continuing firmware, Hatchery, BLE, companion-app, sensor, and reuse work after Camp 2019.
SourceThe repository preserves first, second, and third winner write-ups plus serial, picotool, BOOTSEL, and debugging guidance for people replaying the hardware CTF.
SourceAfter the conference, a badge-number form could output correct hashes to unlock all challenges and add-ons such as Pong, WiFi scanner, and animations.
SourceHackaday documented that the badge could identify as a USB HID keyboard and operate as a configurable macro pad after the event.
SourceThe badge could print button, click, and NFC events over USB, accept content over USB, and work with a repository script that forwarded Linux desktop notifications to the badge.
SourceThe 2016 report describes a Pimp My Badge workshop using the previous year's electronic badge and updating the standard library with additional examples.
SourceThe MT3608 boost converter raises the badge's 5 V supply to the 9 V rail used by the RF detector, and must be adjusted before the RF module is connected.
SourceThe public design notes describe USB or 1S LiPo operation, USB charging, CH340G USB serial, a power switch, and regulator/charger components.
SourceProject details and build logs document two CR123A cells, diode reverse-polarity protection, battery tests, WS2812B failure observations, and boards chainable by VCC, ground, and LED data output.
