Show HN: ESP32 Bowling System technical write-uphttps://nicholas-a-hall.github.io/openlanelink/Hi everyone! I'm the ESP32 Bowling guy from a few weeks ago, back with a technical write-up and a repo link.Since my last post, I've received -tons- of support and encouragement for the project. I'm absolutely blown away. I didn't think there would be much interest!This last week, I spent a ton of time working on the prototype. It can trigger my pinsetter machines and read ball state, there's a basic state machine for the game and a React UI for the bowlers. I've also built the prototype uart bridge which connects an ESP32 gateway node to a raspberry pi lane compute module, which acts as a bridge between the ESPNOW mesh and lane-external services.The last major blocker is object detection on an ESP32-CAM module. I could go with a webcam wired to the Pi, but that feels like cheating. I really want the Pi running the state machine, websocket and REST API endpoints only. One of my key constraints for this project is that each node serves one purpose only, and it performs that purpose wellAug 7, 2026 1:53 PM
