An SRE replaced a $120k proprietary bowling center scoring system with a custom solution using ESP32 microcontrollers, reducing costs to approximately $1,600. The project leverages open-source hardware, computer vision, and RS485 communication to replicate functions previously handled by expensive, aging proprietary hardware.
Background
Proprietary industrial control systems often carry exorbitant maintenance and replacement costs due to vendor lock-in and limited competition. This case highlights the growing trend of hobbyists and engineers using affordable, open-source hardware to bypass these high costs.
