Laser* Tag Badge DS (DEF CON 34)
Pre-event RP2350 infrared game badge with conditional LoRa score sync
Laser* Tag Badge DS is an independent BadgeLife project planned for DEF CON 34. Its maker page describes an RP2350-based infrared tag game with a 915 MHz LoRa score-sync option and QR fallback, while a public late-July update says the boards have arrived and final assembly and flashing are in progress. The record is pre-event and independent; it is not an official DEF CON admission badge.
