A security researcher sets up a Tesla Model 3 car computer (MCU) on a desk using salvaged parts from eBay to participate in Tesla's bug bounty program. The writeup covers sourcing the MCU, touchscreen, and the elusive Rosenberger display cable (eventually solved by buying a full wiring harness), powering the system with a 12V bench supply, and discovering exposed network services including an SSH server and a REST API called ODIN on the internal 192.168.90.x network. Along the way, a wiring mishap burned a power controller chip (MAX16932), requiring PCB repair and a second MCU. The result is a fully booted Tesla OS on a desk, ready for further security research including CAN bus exploration and firmware extraction.
