Bowling center owner builds scoring system with ESP32, saving $118k

Replacement of an Expensive System

The owner of an 8-lane bowling center in a rural town faced the challenge of replacing a six-figure scoring system. The existing setup was installed in 2008 and came with high costs associated with replacements and upgrades. The owner noted the outdated technology required for basic operations, primarily utilizing mechanical components.

DIY Solution Using Modern Technology

In response to the high costs, the owner developed a prototype scoring system using ESP32 microcontrollers. The total cost for this new system is approximately $1,600, a significant reduction compared to traditional solutions. The project showcases the potential of using common components and open-source software to replicate complex systems at a fraction of the cost.

Technical Overview

The new system was designed with a star-topology mesh network configuration using ESPNow, allowing scalability and ease of connection between devices. It integrates various sensors and hardware, including relays and IR sensors, with firmware tailored for bowling lane operations. This process demonstrates how modern tech can transform legacy systems.

Implications for the Industry

This case serves as a practical example of how niche businesses can leverage low-cost technology and DIY solutions to avoid significant expenditures on traditional systems. As open-source hardware continues to evolve, similar approaches may become common in various industries, potentially reshaping the market for legacy equipment.
