Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The maker page describes online leaderboard score syncing over LoRa if RF conditions permit, with QR-code encoding of game data as the documented fallback.
Badge context
Dani Weidman's project page for the 2026 DEF CON 34 Laser* Tag Badge DS. It documents the planned hardware, IR game, conditional LoRa/QR scoring model, pickup context, production caveats, and named project help. Its images are evidence only, not a reuse license.
Dani Weidman's MIT-licensed public OpenLASIR repository for a NEC-inspired 38 kHz IR protocol with 32-bit frames plus MicroPython and Arduino/C++ examples. It identifies Laser* Tag Badge DS as a first-party supporting 2026 badge, but is not a complete DS firmware or hardware-design archive.
Public late-July DEF CON community update saying boards are in hand and final assembly/flashing is underway, with announced DEF CON-week pickup points and a LoRa-or-QR scoring fallback. The post image does not establish reusable image rights.
Source trail
Primary maker source for the 2026 DEF CON 34 DS project, including the RP2350-Zero platform, IR components, conditional 915 MHz LoRa radio, displays, LEDs, controls, 18650 battery, SAO-port limitation, game rules, pickup plans, and production/RF caveats. It does not provide reusable image permission.
Primary public protocol source with an MIT license, NEC-inspired 38 kHz carrier and 32-bit framing documentation, MicroPython and Arduino/C++ examples, and a first-party reference to the 2026 Laser* Tag Badge DS. It does not establish a complete badge firmware, badge PCB archive, or final production build.
Public late-July pre-event update corroborating that boards had arrived and final assembly and flashing were underway, plus announced pickup and LoRa/QR-score-sync context. It is used conservatively as a production-status update, not as a final fulfillment report or reusable-image license.
