I replaced a $120k bowling center system with $1,600 in ESP32s

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

In plain words

A bowling center operator replaced an aging $120,000 scoring system with a custom solution built on ESP32 microcontrollers costing $1,600. The system handles ball speed and trajectory detection, camera-based pin detection, fouls, animations, and scoring displays for an eight-lane center. This project serves a rural community seeking recreation options while demonstrating how modern microcontroller platforms can replace expensive legacy equipment in commercial bowling operations.

  • I built a handheld CHIP-8 game console to teach myself embedded systems2022 · github.com · ▲128

    A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

    Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

    Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  • Getting GLM 5.2 running on my slow computer▲937

    A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

    Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
