🟢 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.
