Lighting
Obstacle LEDs and independently powered floor; DMX is a future option.

Engineering
Arena lighting — obstacle LEDs and separate floor prototype / plans
Reviewed 2026-11-11. Current obstacle firmware renders local effects on one 5m WS2815 roll. The floor is an independent server-event appliance with its own controller and PSU. Strips create ambient light, spell paths and zones in a darkened room.
Current LED control
/smart_block WebSocket fx / verdict → local ESP32-C6 animation,
GPIO2 through AHCT125. The standard dispatcher broadcasts; per-obstacle addressing needs the documented registration fix.
Future venue lighting
Art-Net/sACN, venue-wide LED mapping and 4–6 DMX tracking heads are future options. The historical ~250m / ~15-block plan and ~104k CZK optional DMX line are estimates, not installed hardware. DMX is excluded from the historical ~324k CZK core venue CAPEX.
Fixture mounting, aiming limits, intensity and E-stop require final installation design and acceptance. Concept/engineering illustrations depict an earlier venue plan.
Mapped floor cross prototype
Admin → Room → Arena planner places the controller center/yaw, objects and 600 physical addresses.
Gateway computes the same RGB frame for preview and the independent floor_led_sw firmware.
Four 150-pixel arms use GPIO2/3/6/7 through AHCT125; one RMT channel switches outputs sequentially.
GST280A12-C6P 12V/21A supply, 20A main fuse, four5A arm fuses and a2A logic branch. Both ends of each arm share one fuse. Provisional load185W from9W/m reference; purchased reels need measurement.
