🎳 Bowling System Cost Comparison

How much does it cost to replace a bowling center scoring system? Depends who you ask.

🏢 Commercial Vendor

$100,000

per 8-lane center (installed)

Proprietary hardware · Vendor-specific cameras · 2008-era ICs · Service contract sold separately · Every feature a line item · $4,000 per lane pair for replacement parts · No open APIs · You own nothing, you're happy

🔧 OpenLaneLink

$1,600

per 8-lane center (prototype)

Off-the-shelf ESP32s ($6 each) · IR break-beam sensors · RS485 fallback · Raspberry Pi gateway · Redis event stream · React frontend · Spare controllers in a drawer ($20) · Swappable in 10 minutes · Full data ownership

Total savings on an 8-lane center

~98% — $98,400 saved

⚙️ Tech Stack Comparison

🏢 Commercial ($100k/lane pair)

Proprietary embedded ICs — no datasheet, no schematic, no hope
Vendor-specific camera modules (part #: call us)
Custom cabling — pinout changes every model year
Single-vendor service contracts ($5k+/year)
Closed firmware — zero modification possible
No API, no webhooks, no export
White-label themes cost extra (yes, really)

🔧 OpenLaneLink ($200/lane pair)

ESP32-S3 — $6 on Amazon, datasheet at your fingertips
IR break-beam sensors — $3 each, any electronics shop
RS485 + ESPNow mesh — dual-path reliability
Raspberry Pi gateway — $35, spare SD card in drawer
Redis event stream — pub/sub pattern, every dev knows it
React frontend — any web dev can build a new UI
Open source — planned for full release

🐸 Pond wisdom: When the vendor quotes six figures for a relay trigger, the problem isn't the relay. OpenLaneLink shows what happens when you own the building and the stack. The pond remembers both invoices.

Based on section33's Show HN (2,625 pts) — an SRE who bought an abandoned bowling alley and built an ESP32-based scoring system called OpenLaneLink. Read the full story →
