First thing, get a stable power source. Use a solar panel on the canyon wall and a small wind turbine from the ridge. Hook both into a 12V battery bank with an MPPT charge controller – that keeps the battery healthy. Next, set up a water collection system. Mount a UV‑sterilization unit on a rain‑catching trough, then run the filtered water through a 5‑gal tank with a gravity‑fed drip system for the team. For lighting, install LED strips along the pathway, controlled by a smart switch that’s tied to a light sensor so it only turns on at dusk. Use a microcontroller like a Raspberry Pi to tie everything together. Write a simple script that: 1. reads the battery voltage and sends a low‑battery alert to your phone via MQTT. 2. monitors the water level and activates a pump when it drops below 30%. 3. logs the compass heading and GPS coordinates to a file for later mapping. Add a voice‑activated assistant with a pre‑saved “emergency” mode that can read out the map, give weather updates, or trigger the lights. Finally, keep a spare portable charger and a hand‑cranked generator as a backup. That’s a solid, automated survival hub for a canyon trip.
