I wanted a home security drone that could actually navigate my house, hold a conversation, and tell me when something was wrong — without phoning home to a cloud server I don't control. The Ring Always Home Cam is invite-only and has been for years. So I decided to build one.

This is the full build log. Every hardware decision, every mistake, every measurement. I'm documenting it because I couldn't find anything like it when I started — most drone build logs stop at "it flies," not "it navigates your living room at 2am and tells you the smoke detector's about to go off."

Professionally, I'm a VP of Corporate Development at a digital twin company, with a background in mechanical engineering. I've been designing and building things my whole life — this is just the first time I'm doing it with a Raspberry Pi and a LiDAR sensor instead of a CNC router. The fabrication instincts transfer surprisingly well.

I post progress updates and build decisions on LinkedIn as the project moves forward.
