I turned my DJI Mavic into a home security drone with REA & Opus 5.5.
this f*cking is insane..
I reverse-engineered my DJI drone with Opus 5.5
no cloud. no GPS on the target. it all runs on the phone. iPhone or Android.
here's the build step by step:
step 1 → plug a spare phone into the Mavic remote and paste the prompt below into Claude Code on Opus 5.5
step 2 → Opus checks your drone against the DJI Mobile SDK v5 list. not on it?
stop there. no firmware hacks
step 3 → it builds a small app on the official DJI SDK: Swift for iPhone, Kotlin for Android
step 4 → sync with the alarm: Home Assistant sees it trigger → push to your phone → one tap "Launch"
step 5 → eyes: a tiny YOLO model on the phone's chip. Core ML on iPhone, LiteRT on Android
step 6 → memory: a Kalman filter. he runs behind a fence → LOCKED → COASTING → re-locks on the same ID
step 7 → hands: Virtual Stick at 10 Hz. box center → yaw, box size → distance, never closer than 8 m
step 8 → at the property line it stops, climbs to 30 m and keeps the camera on him until he's out of sight
step 9 → lands back on the pad. the clip with track, distance and timestamps is already on your phone
the alarm wakes you up. the drone already knows where he went...
