We (tscircuit) are trying to develop a PCB fabrication method that's compatible with US regulation (i.e. a dry process without etchants)- we're seeing awesome results using UV lase…

tscircuit! An open source framework for building circuits, we have a lightening fast autorouter so i spend lots of time debugging complex PCB routing problems

We work on this a lot at tscircuit, and we've used cassowary (i.e. flexbox-style) constraint solvers. The issue with cassowary/flexbox is PCBs are not as uniform as webpages w.r.t.…

> To me innovation in autorouting means being able to 'have a conversation' with it: being able to easily adjust things and see the results and map out the tradeoffs would be very …

author here: I think synthetic data, generated by ~brute force iteration with LLMs, with every DRC analysis imaginable and more, will yield a more consistent/usable/larger dataset …

Author here. Happy to hear thoughts on this article! Our goal is to make a "realtime PCB autorouter", which means every millisecond matters!

Hello everyone, just wrote this article to hopefully save someone a year of time while building an PCB autorouter. Enjoy! Here for questions.

Game developers do bake navmeshes that's true, but it's not the only technique, for example they've also come up with Polyana or "any-angle pathfinding" https://github.com/vleue/po…

Despite what electrical engineers would claim, I think it's very under-studied under a modern lens. When people ask for good places to get started I usually tell them to just look …

I've been begrudgingly working on autorouters for 2 years, looking for new techniques or modern methods that might allow AI to create circuit boards. One of the biggest problems in…

This is sort of the premise of all of us electronics-as-code startups. We think that a text-based medium for the representation of circuits is a necessity for AI to be able to crea…

Isn’t this just Apache 2-style permissive licensing?

Strongly disagree with the article. Enums make gradual migrations impossible in both databases and API design with third party consumers. Even in the example they gave where they r…

Awesome to see more people experimenting with AI-generated electronics. The main thing holding back physical world innovation is the labor cost of design- I’m always blown away tha…

There's a lot of potential for desktop rapid-prototyping with electronics. I think one of the things that is killing us is the tooling. One of the reasons I started building an aut…

Hardware is becoming more accessible, so more software companies are going to release hardware products or build hardware products for internal purposes. The future of physical wor…

I've updated the article with the fixed projection transform! I had to make an animation as well just to validate it- I fooled myself!

Your renderer looks awesome! I was surprised there wasn't an "off the shelf" SVG renderer in native TS/JS, it's a big deal to be able to create 3D models without a heavy engine for…

Circuit boards have holes, cutouts and import STL/OBJ components that we'll eventually support in this 3d renderer. Assuming we get that far I may have to rename it from "simple-3d…

I was at least a little confused because yea fish eye isn’t possible with a 4x4 perspective transform matrix. I’m investigating an issue with the projection thanks to some help fro…

We could absolutely use isometric projection, but personally I find them a bit hard to visually parse.

That admittedly looks a lot more correct! Thanks for digging in, i will absolutely test and submit a correction to the article (i am still concerned the straight edges are misleadi…
