DEF CON Singapore 2026 · Singapore · 2026
Maker-documented RP2040 community eBadge with firmware, art, and SAO sources
RestiaAshdoll8's public DEFCON-SG-2026-Div0-Tingkat-eBadge repository says it contains source code and relevant files used in a physical Div0 Tingkak eBadge. It preserves a UF2, RP2040/Pico-focused source, artwork, and SAO project files. Its sources conflict on event identity: the repository title names DEF CON Singapore while its firmware menu banner says SINCON 2026 BADGE. This record keeps the DEF CON Singapore association maker-declared rather than resolving that conflict into official event status.
People
Division Zero's own recap confirms its hands-on SG Community presence at DEF CON Singapore 2026. It does not name the archive or establish badge authorship, issuance, production, distribution, official approval, or image-reuse authority.
SourceThe public GitHub account publishes the commit-pinned archive and README. This handle-level credit records source publication only; it is not expanded into a verified real-world identity, sole design/firmware/artwork role, manufacture, event authorization, distribution, or image-reuse credit.
SourceIt records a distinct, source-published Singapore electronic-artifact trail without merging it into the official DC-SG-1, the HFSDR, the Public Safety Village badge, or the TISC finalist trinket. Keeping the repository and firmware labels side by side makes the uncertainty visible instead of silently assigning a maker archive to either DEF CON Singapore or SINCON.
The public code imports Raspberry Pi Pico SDK headers, and its accompanying board-support notes are explicitly RP2040-focused with an rp2040:rp2040:rpipico FQBN example. Its pin map declares UART, two buttons, a WS2812 data line, I2C OLED pins, and analog/digital challenge GPIO. The root tree includes a UF2 and separate SAO EDA/coin-cell-adapter files, but no disclosed main-badge schematic, PCB layout, BOM, exact controller package, board revision, power source, unit count, or physical build photo tied to this archive.
The archive publishes Arduino/Pico-style source and a UF2 with a serial menu plus LED, OLED, and challenge modules. Its README describes older and newer firmware presentations and a battery-oriented firmware tradeoff affecting ordinary USB challenge access. No tagged production release, source-to-unit map, final build configuration, complete challenge deployment, or evidence that every physical badge used the same firmware is public; the catalogue does not reproduce flashing, serial, or challenge-solving procedures.
The repository separates art and SAO directories, with Singapore food-themed filenames including chilli crab, kaya, and kueh alongside the SAO EDA files. It does not say which artwork or SAO variation shipped, whether any complete unit was distributed, or why the README spells the artifact Tingkak while the repository title uses Tingkat. Division Zero's post-event community recap confirms its hands-on presence at DEF CON Singapore but does not name this exact archive.
Source-backed hardware metadata
Structured technical signals seeded from public badge documentation, repositories, schematics, firmware notes, or event evidence. These fields are designed for filtering, API use, repair planning, preservation, and future Companion Gear matching.
The commit-pinned maker README says the archive contains source code and relevant files used in a Div0 Tingkak eBadge, including firmware, art, and SAO files. Its DEF CON Singapore repository title and SINCON 2026 firmware banner conflict, so event association, official status, configuration, and distribution remain separately bounded.

Operational history
The entry retains a useful public firmware trail without turning it into operating instructions, a security challenge walkthrough, a guarantee of USB behavior, or proof of a final event configuration.
Readers can inspect the source-backed electronic surface without treating it as an electrical guarantee, a safe host/SAO compatibility statement, a full open-hardware release, or proof of how many real badges were made or received.
No repository art, PNG, screenshot, source graphic, social image, or generated approximation is copied into the public image directories; the record remains source-linked and image-free pending complete reusable-image provenance.
The record preserves the maker-declared DEF CON Singapore association while explicitly avoiding a claim of DEF CON or SINCON official issuance, attendee-wide allocation, organizer authorization, sponsor status, credential function, or an event-specific final handoff.
The Singapore record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
