24 alternatives to 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…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hello, we're Max and Byran from MUREX Robotics, a high school robotics team from Exeter, New Hampshire. We are super proud to have made this open source piece of technology! It is only 6.9 dollars (actually!) from JLCPCB :) I hope you like it. You can find us at [email protected] and [email protected] as well if you have any questions. We will be putting a small run of these boards for sale somewhere (we have <25 units of stock), probably for $10+shipping. Let us know if you're interested in more! Board files for everything we make is here:…

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…

I've never posted on ShowHN before, but I wanted to share my Xmas 2025 project; to try a new approach to controlling our kids screen time. This also involved massively over-engineering a solution in order to play with a shiny new gadget (and avoid the in laws at Christmas, obviously) I've shared some learnings on AI coding with embedded devices, and how I approached the product design/hardware selection side of things. The Web App is at https://screenie.org - and I'm Open Sourcing the device and web app code later today (links to follow on that site)

Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.…

I’ve always found it funny how simple feedback widgets end up as $20–$30/month products. The tech is dead simple, infra is cheap, and most of us here could rebuild one in a weekend. So as a “principle experiment” I built my own today as a side project and priced it at 1 dollar. Just because if something is cheap to run and easy to replicate, it should be priced accordingly, and it’s also fun marketing. 1$ feedback tool. Shipped today, got the first users/moneys today, writing this post today. Side Sunday project, then back to the main product tomorrow.

This was not supposed to become a product. When PaddleOCR-VL-1.6 dropped, independent benchmarks put it at the top of document parsing models. I had to try it. I needed a provider, but there simply isn't one ready for production that I would trust. So i set one up myself. I assumed that even after getting it running, serving a vision-language model would be expensive. It turns out the opposite is true. Once I had it running properly, the cost was absurdly low. At proper GPU utilization, the cost is only around $1 per 1,000 pages. The nearest competitors are either much lower quality (Azure…

Hey, my name is Ivo and I'm a startup enthusiast. I'm a huge poker fan and I've been watching poker streams for a while. I always wondered how they do it how they display those cards on the screen, do they have somebody watching the cameras and entering all this data manually, is there a fancy image recognition AI model in the background? It appeared to be much simpler with the help of RFID. Each card has an RFID chip with a unique ID, and each player has an RFID scanner below the table, once the scanner detects the cards voilà we know what card the player has. Once I found how it worked I…

Hi HN, When I was in FAANG, I despised ticketing. I was always the eng that refused to update. Then when I was a tech lead, I had the pain of pinging everyone for updates because they hated it too. Things would go out of date, and then no one would really know if we were on track. We also had little visibility into what the team was doing outside of pinging/standups. So I made an AI that looks at every commit you push and updates tickets for you. It can create tickets if there isn't one, update, leave comments, tag associated commits etc... Basically, it's an "AI Board Babysitter" so…

I kept on reading you guys on how to do it, how not to do it. On January I started with thinkpython, learn python the hard way, mit course on programming, and every other python material I found. You just need to find the best resourse for YOU. I did Udacity's CS253 course, got my certificate and made my MVP! If your one of those guys like me, just get your ideas out there and the project will push you forward. Farm management software in South America is broken. We still have cd and downloadable updates. We've seen www.farmlogs.com and www.farmeron.com for USA and Europe. How about…
