	tl;dr: An SRE who bought an abandoned 8-lane bowling alley is replacing its $80-120k proprietary scoring system with a $200-per-lane-pair DIY rig built on ESP32s, ESPNow mesh (with RS485 fallback), and a Raspberry Pi running Redis and a state machine. The stack exposes events to standard web tooling, allowing custom React-based UIs and animations. He plans to open-source the hardware, firmware, and software as OpenLaneLink.
	HN Discussion: ↑Retrofitting legacy systems with cheap modern embedded tech is a broadly untapped opportunity ↑Fellow bowling enthusiasts share their own similar projects or experiences with old machines ↑Excitement about expanded feature possibilities like LED effects, slow-mo replays, and kiosk payments ↑Proprietary bowling equipment pricing is absurdly overpriced, validating the DIY approach •Requests for more documentation, photos, videos, or a shareable URL about the build
