🟢 That green light glowing in the dark is a mesh radio, GPS receiver, AI assistant, and emergency communications terminal — all running on battery inside a weatherproof aluminum box I built from scratch. Meet the Cochrane Device — S/N 001. After Hurricane Maria knocked out communications across Puerto Rico for months, I wanted a way to keep my family connected when everything fails. No cell towers. No internet. No power grid. So I built one. 📦 Inside the IP66 aluminum enclosure: → Meshtastic LoRa mesh radio — encrypted, 15km range per hop → GPS with 3D fix in 18 seconds → WiFi hotspot so your phone becomes a node → Linux computer running full service stack → AI assistant that writes scripts on demand in the field → Remote access via Tailscale from anywhere on earth → 6-8 hours battery, solar chargeable This is S/N 001 — the prototype. Every lesson learned here makes the next one better. 🖖 #Meshtastic #LoRa #EmergencyComms #PuertoRico #OffGrid #Linux #Maker #DIY #HamRadio #OpenSource
