TL;DR
HN user section33 took on the challenge of replacing an outdated and costly scoring system at an abandoned 8-lane bowling center. The original system was priced between $80,000 and $120,000, with parts costing around $4,000 per lane pair. Instead of spending that much, he developed a more affordable solution called OpenLaneLink, which utilizes ESP32 microcontrollers to manage the scoring system for just $200 to $400 per lane pair.
