HN: Open-source bowling alley control system built with ESP32s
A bowling alley owner describes replacing a proprietary lane-scoring and control setup costing tens of thousands of dollars with a custom system built from ESP32 microcontrollers. The prototype uses ESPNow, RS485 fallback, a Raspberry Pi lane computer, and Redis to handle sensor events, relay control, and UI updates, with plans to open source the hardware, firmware, and software stack.
