This looks really cool! Nice work
Re:Household Laser Cuts on Sunday September 06, 2026 @12:47PM (#49588309)
I found that Figma is really good for designing SVG laser cuttable designs. Had to fix a few things with exports, units etc. but solid. Here's a little plugin I built if it's helpful:

Re:OpenAI Should Build Slack on Saturday February 14, 2026 @11:45PM (#47021133)
I think a slack clone with better message search, a company knowledgebase, and a personal “auto-responder” could be a winner
Re:Show HN: CodeMic on Wednesday February 11, 2026 @04:31PM (#46981351)
This looks great! I'm trying to open a video to test it out. My VSCode seems to open, but the session doesn't launch. Am I missing something?
I've been waiting for something like this for ages. Hope there's auto-playing video ads too
Re:IsoCoaster – Theme Park Builder on Monday February 02, 2026 @03:54PM (#46861395)
I never played RCT, I thought this was really fun and was hooked for a good minute.

Ran smoothly on MBP M1+Chrome. I couldn't figure out how to start the kiddie rides or get people through the doors initially. It might be fun to have some kind of daily challenge or competing with other parks. I found clicking in the 3D space to a little tricky.

Re:Bugs Apple Loves on Thursday January 22, 2026 @10:03PM (#46727852)
Wow, the first three "bugs" on this are so spot on.

The Apple Pay Card icon that changes addresses always gets me. It's not what I would expect it to do.

Re:Show HN: We added iOS real device support to Maestro on Thursday December 11, 2025 @02:22PM (#46235915)
If you don't know what Maestro is:

> Maestro is an open-source framework that makes UI and end-to-end testing for Android, iOS, and web apps simple and fast. Write your first test in under five minutes using YAML flows and run them on any emulator, simulator, or browser.

Re:Better Than JSON on Monday December 01, 2025 @02:41PM (#46112083)
I wonder if we can write an API w/ JSON the usual way and change the final packaging to send it over protobuf.
I think this is cool! Honestly it’s one less click back into an IDE. I think I’d still have to hop back to commit to git, but it’d save me all the copy+paste time (esp w/ css styles).

I hope there’s a right click, “edit JSX” button.

Re:Processing Piano Tutorial Videos in the Browser on Monday September 08, 2025 @05:04PM (#45173972)
Hooray! Yeah, give it a try.
Re:Processing Piano Tutorial Videos in the Browser on Monday September 08, 2025 @05:03PM (#45173961)
Oh I love this. And it'd be really cool to see that.

The current output isn't a particular format. It's purely text output that looks like this.

1:01 -----|A1--B1|----A3--A4|

1:03 -----|A1--B1|--A3--A4|---B2|

If you had a way to copy and paste that as a string of notes and visualize in a loop or some-how that might work. You'd have to figure out how long a note was pressed etc, so it may require some extra logic.

Re:Processing Piano Tutorial Videos in the Browser on Monday September 08, 2025 @04:58PM (#45173897)
Oh yes, there's a lot of songs that are published in the tutorial video format, but the MIDI source isn't shared.
I’ve always struggled to keep up with piano tutorial videos. The notes fall too fast to make any sense for me.

So I put together a small tool called Piano Reader to see if it could catch the chords and notes.

Re:Show HN: Twick - React SDK for Timeline-Based Video Editing on Wednesday August 20, 2025 @03:03PM (#44965115)
I like this, and much needed.

That said, a simple hosted demo or code-sandbox would make this easier to demo and test as a user. It'd help to see the expected behavior as well. I don't want to checkout the repo or spin up a sandbox.

Huge inspiration! I loved the anyon_e videos. He DIY'ed the laptop and made it look really nice.

Thanks for sharing! Agree, building hardware hasn't been the easiest thing.

Interesting, I like the idea of a custom screen on the Framework. I'm sure that may come with its own challenges as well :)

Re:Ask HN: What are you working on? (May 2025) on Sunday May 25, 2025 @06:20PM (#44091743)
I've been working on an e-ink laptop. I wanted a machine I could stare hours at and feel okay about it. I didn't seem to find a device like that out there.

I'm designing everything from the chassis to the software OS. E-ink has its own design constraints. I'm building 5 apps for it: a browser, reader, mail, writer and code editor. It's still a ways to go. Here's a picture of what I have so far:

I have a 25.3. Flicker issue is real. I’ll have to try this out. Thanks for sharing
I wonder if I could write my own software for this car? Like auto-sensing rain-wipers with an Arduino or something, and if the CAN BUS protocol isn't super hard to use. This would be a car hacking dream.
