Smart props
Chests, tomes, fog screens — later immersion phase.
Engineering
Smart props & immersion extras planned
Future physical objects proposed to reuse the UWB infrastructure and gateway game logic. Software treasure nodes already exist for hardware-free testing.
Treasure chests / ward crystals
Physical ESP32 + DWM3001C (+ optional 12 V solenoid latch) is a future design, not verified prop hardware or automatic mapping. Gateway TreasureNode
already implements unlock-by-aim, loot tables, HUD/Unity events. Virtual nodes at
(±5, 0, ±5) seed without hardware; the Playground map places more in one click and
shows the lid opening in 3D. Admin: /admin/treasure.
Spell tomes
Pedestal displays — MAX7219 32×8 or E-Ink on ESP32 — show leader, countdown, sudden-death. Keeps eyes in the arena, not only on the wand PWA.
Fog screen
PVC + ultrasonic mist + fans → doorway mist sheet; budget pico-projector for floating imagery. Players walk through or cast at it.
Haze / shrines
Water-based hazer for beam visibility (air-change rules apply). Shrine/beacon re-zeros remain a design target. Current operation uses explicit point alignment/triple-tap calibration; calibration-free match behavior is not validated.
