SimOS
Commercial sim racing rig controller bridging 60Hz telemetry, ESP32-S3 hardware nodes, QR scan-to-race, and intelligent stint billing.
SimOS is a three-tier commercial sim racing automation platform that turns high-end racing simulators into self-operating, revenue-generating entertainment and driver-development hubs. Running a local Python bridge, SimOS captures 60Hz iRacing telemetry to drive ESP32-S3 hardware nodes controlling active wind simulation, 300+ LED rev displays, and pedal haptic feedback. It features intelligent stint lifecycle management (pit-exit clock trigger, "finish your lap" grace buffer, and hardware exit macros), integrated with QR scan-to-race credit billing.
