I hope Anthropic will reset my Claude usage as i'm already at 75% weekly usage :)

I'm thinking it would be really cool to have something like Wikipedia, but with expert knowledge structured as a graph. If you have any ideas or know if something like this already exists, please let us know ;)

looking forward to letting the Bible speak to more and more people every day

If you'd like to find more boards where you can flash your firmware, you can check out: https://openhardware.directory/devices/search/home-assistant...

Here you can find some Meshtatic devices, some of them which can be paired to your phone using BLE: https://openhardware.directory/devices/search/meshtastic-com...

we were scraping the prices using claude code and pushed them with an mcp to the directory

yup, we have to work on improving the search, this is just the MVP :)

Yes, we need to better explain our name. I was creating this website for myself because I'm a developer and I want to change the firmware on existing boards, as I don't have that much experience with electronic circuits and so on.

by open, we mean that you can flash your own firmware. - but yes, we will need to check manualy each device/board or improve the Claude Opus prompt to make sure that it's doing a very good research when extracting these devices

we are scraping the products using Claude Opus and we also saw some problems.. we will have to review everythign manually and improve (not an easy job.. but if it's useufl for people, we will do it -- i did not expected so much demand for it)

yeah, it's true, but the idea was to also have some useful peripherals indexed, so when users are searching for a use case, they'd also have these plug-and-play peripherals in the search results.

but i'm open to feedback so we can make a better experience for all of you ;)

iosifnicolae2 — Wed, 18 Mar 2026 16:07:29 +0000

yup, i totally agree. i was focusing on the functionalities first, later we can do a redesign to not feel like ai slop

yup :) thx for the feedback

- by default, we are displaying all the devices so you can just scroll through the list - if you want to get all the devices for a specific use-case, you can setup filters

- no, the search list is not secret.. you can even convert any page to markdown https://openhardware.directory/devices/md - you just have to add /md to any page

- also, you can browse it with llms.txt (https://openhardware.directory/llms.txt)

I'm open to new ideas on how to improve the search experience

Yup, it will take a bit of time until we index as many devices as possible. Also, we need to invest a bit more to make the AI search faster and much better. (If anyone has any ideas, we're open to feedback.)

Also, I'm curious — how do you think we can make the device pages even better? My personal problem is that I want to find devices for a specific use case, and the issue is that it's pretty hard to extract real-life use cases for all the scraped devices. We will need a way to extract these insights from the internet.

now, we've indexed 463 :) but we will index more and more boards and make the platform as good as we can

Show HN: SmartRuler Pro – ESP32-powered motorized ruler with 0.5mm precision

iosifnicolae2 — Tue, 03 Mar 2026 18:28:36 +0000

My dad cuts window profiles in his workshop and I kept watching him measure, mark, and reposition by hand hundreds of times a day. So I built him a motorized ruler that moves to any position you tap on a tablet.

It runs on an ESP32-S3 over BLE 5.3, uses hardware-timed stepper pulses (RMT peripheral, no CPU jitter) to hit 0.5mm accuracy, and pairs with a Bosch GLM laser meter - point, measure, and the ruler moves there. No typing, no transcription errors.

You can also upload cut lists from a file or email and it runs each position in sequence - perfect for batch cutting window profiles where you need the same set of measurements repeated all day.

Open hardware: off-the-shelf linear rails, NEMA 23 closed-loop stepper, inductive homing sensor. Total BOM is about 470 EUR. I sell the firmware, app (Android + desktop), and a step-by-step build guide for 350 EUR.

Video demo: https://youtu.be/GCUHBiIs4Vk

Happy to answer questions about the build or the ESP32 RMT approach to stepper control.
