BalCCon Mini Cyberdeck 0o00
MC-0o00 CH32V003 mini cyberdeck badge
The BalCCon2k24 MC-0o00 badge scaled the cyberdeck idea down to a CH32V003 RISC-V board with LCD, six buttons, buzzer, GPIO/power interface, and the ability to connect to BCD-0o27.

Hackaday Supercon 2024 SAO Badge
Six-port Pico W SAO hub
The Supercon 8 official badge used a Raspberry Pi Pico W and six SAO ports as an I2C playground, bundling touchwheel, LED petal matrix, blank protoboard, and CH32V003 I2C proto-petal add-ons with MicroPython examples.
Hackaday Europe 2025 SAO Badge
Berlin reuse of the Supercon 8 SAO badge with revamped firmware
Hackaday Europe 2025 reused the Supercon 8 Simple Add-On badge concept in Berlin: an SAO-focused badge with I2C/GPIO exposure, MicroPython lineage, revamped Europe firmware, Supercon contest-winner add-ons, and badge-hacking ceremony context.
La Villa Hacker 2025 Badge
Electronic Cats OLED and nRF24L01 village badge
Electronic Cats' public La Villa Hacker 2025 Badge repository documents a village badge with OLED display, nRF24L01 radio, two-AAA power, Shitty Addon connector, KiCad hardware files, firmware sources, and a released VillaHacker.hex binary.
C1B3RTR4CKS 2026 CH32V003 Badge
Source-backed RGB LED-matrix event badge
SEIF-UAM's public C1B3RTR4CKS 2026 badge repository documents an event badge with a CH32V003 RISC-V microcontroller, 8×16 RGB LED matrix, five-button control surface, public C firmware, games, and a personal-name marquee. The official event site and a contemporaneous attendee report place the physical artifact at the completed May 29 Madrid event; final allocation and production details are not public.
DFIU SAO (DEF CON 34)
Independent CH32V003 touch-and-audio SAO announced for DEF CON 34
BigFuckingBadge's live DEF CON 34 page presents a $20 OffensiveSAO around touching Lintile's face to play a "Don't Fuck It Up" cheer track. The public DEF CON 34 Badgelife response identifies that item as the DFIU SAO from BigFuckingBadge / Hexum064 and links public CH32V003 hardware and firmware repositories. The firmware's PlatformIO target is `genericCH32V003F4U6`; its `main.c` initializes touch ADC support, reads a touch input on PD2, starts sampled audio when the threshold is crossed, and configures a PWM audio path plus D/F/I/U and display LED outputs. The public hardware tree contains a KiCad PCB/schematic, BOM/position files, and Gerbers. Together these sources establish a real planned independent electronic SAO associated with DEF CON 34—not an official DEF CON issue, admission credential, confirmed handoff, final production revision, safety-tested product, open-source license grant, or rights-cleared image.
Greycademy 2026 Hackbadge
Source-backed CH32V003 student-bootcamp electronic badge
Hackin7's public project page identifies a deployed electronic PCB Hackbadge created for Greycademy 2026. NUS Greyhats' official announcement says program participants could take home electronic badges, while the primary maker record identifies a CH32V003 coin-cell design and reports an event-day power-reliability repair across more than 200 programmed units. The public trail does not define every recipient, final firmware image, or all-unit configuration.
Not Just a Crosswalk SAO (DEF CON 34)
Planned open-hardware CH32V003 light-up Simple Add-On for DEF CON 34
The maker-owned public `keeloi79/not-a-crosswalk-sao` repository explicitly calls Not Just a Crosswalk a Simple Add-On (SAO) project for DEF CON 34. Its README documents a CH32V003 F4P6 RISC-V controller, eighteen side-emitting addressable LEDs, persistent palette/effect settings, two controls, 3.3 V host-badge power stepped to 5 V or a USB-C 5 V input path, and claimed SAO V1.69bis/V2.0 compatibility. The source tree includes documentation, schematics, firmware, build instructions, and a three-part license declaration: CERN-OHL-S v2 hardware, GPLv3 firmware, and CC BY-SA 4.0 documentation/creative works. This is a source-backed planned independent DEF CON 34 add-on, not evidence of a final manufactured run, price, sales channel, quantity, pickup, recipient, host-badge test matrix, electrical-safety validation, official DEF CON affiliation, admission right, or rights-cleared badge image.
Ouroboros Badge (DEF CON 34)
Independent CH32V003 bare-metal UART crypto-puzzle badge offered toward DEF CON 34
K Badges' maker-controlled Tindie listing identifies Ouroboros as a $29.99 bare-metal RISC-V-assembly electronic badge on a CH32V003, with a custom UART cryptographic puzzle, a 12-LED Charlieplexed matrix, a circular single-layer PCB with exposed traces, and a hand-soldered two-AA configuration. Its August 4, 2026 storefront snapshot is out of stock; the seller says a new order is coming and hopes to bring some to DEF CON, rather than confirming units, arrival, pickup, or delivery. In a first-person r/Defcon announcement, the maker says they created the project and links the Tindie page and a GitHub technical explainer, while separately offering to arrange a DEF CON pickup by email for Tindie buyers. The product also makes 115200-baud puzzle, cryptographic-framework, low-power, and performance statements, but neither the product nor the maker-linked generic AVR framework establishes a released matching CH32V003 firmware or hardware package. This is a source-backed independent pre-event maker offering, not an official DEF CON badge, registration credential, confirmed fulfillment, verified cryptographic implementation, hardware-safety record, or reusable-image source.
