Badges
ESP32-C6 attendee badge with Laser* Tag and hardware-hacking workflow
The inaugural DEF CON Singapore attendee badge, DC-SG-1, is an official electronic badge issued to ticket holders. Public event workshop and game documentation identifies an ESP32-C6 platform with eight megabytes of flash, an interactive hardware-hacking workflow, USB-C access, and a conference-wide infrared Laser* Tag game.
Unofficial CH32V305 SDR badge preorder
A community HFSDR badge preorder for DEF CON Singapore 2026, documented through Hackin7's r/Defcon preorder post and the linked public rhgndf/hfsdr hardware, firmware, host-software, and WebUSB archive.
HTX village badge with illuminated public-safety icons
HTX's official DEF CON Singapore coverage documents Public Safety Village badges, including a badge image described as featuring illuminated icons of emergency vehicles, alongside the first DEF CON Public Safety Village.
CSIT C517 finalist BLE mesh challenge hardware
A source-backed TISC@DEF CON SG finals challenge artifact: CSIT's official C517 page documents the on-site TISC finals, and a finalist writeup says each of the top-50 finalists received an ESP32 hardware trinket running a customized BLE mesh chat protocol to reverse engineer.
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.
