    The space is definitely heating up.

    Flux.ai being the incumbent Silixon based out of the UK have been showing demos Quilter and DeepPCB for layout The recent OpenAI demo...

    I went the other way and pre-designed sub circuits with a set of rules that allows simple merge assembly, unfortunately I didn't have the time or budget to continue with it, but I took the constrained approach as with hardware, things can't be 99%.

    The one thing I will say, is that my experience of hardware engineers is very gatekeepy.

    Any questions about the use of AI for any form of automation on forums/Reddit get shot down instantly and the OP's told 'skill issue' more or less. In my opinion, just as with software, most work is simple and should be automated, there will always be a need for the real engineering when it comes to high specification work, high volume optimisation and hardware debug (although Claude code is pretty handy at driving a Jlink)

      Stay away from Reddit and forums if you want to see where the open minded people are looking. There are a lot of communities where EEs are experimenting with newer technologies and sharing their results, with realistic appraisals of what can be done.

      You also need to understand the history of autorouting technology for PCBs. Autorouters with auto layout have been around in many forms for years. Their output never compares to a skilled EE doing it manually. The gap between autorouter output and skilled operator output is even bigger than the gap between a good developer and average AI codegen slop.

      I’m interested in this space, but even the Fable/Astra or dedicated tools like Quilter, Flux, and others have a very, very long way to go for boards more complex than simple hobby boards.

      I do think this is going to be good for hobby people doing simple PCBs though

        NP-hard problems are still NP-hard even with magical LLM pixie sprinkles. =3

          If the magic LLM pixie sprinkles can brute force their way to a solution using viable heuristics and their training data, I will use them.
          • Joel_Mckay 6 minutes ago
            NP-Hard is NP-hard... "heuristics" in this case is just a euphemism for a fantasy cost-function to scam shareholders.

            It is a named problem, and can't be misappropriated like the $9Tn worth of FOSS code "AI" scraped and compacted for isomorphic plagiarism tokens. =3

          Magical LLM pixie sprinkles ... is that where magic smoke comes from?
          • Joel_Mckay 20 minutes ago
            Magic smoke is important, as it indicates a design parameter was exceeded.

            I often recommend folks get a mini thermal camera for their phone... as inspecting for issues in electrical, hydraulic, or mechanical systems gets a fair bit easier/safer. =3

        • monocasa 1 hour ago
          They're also NP-hard for the humans doing the majority of the work currently, meaning that good enough heuristics dominate as it is.

        Where are these communities?

    This is probably not the primary way people use the tool, but if I log in (desktop, Chrome on macOS), click "Start a board" on the sidebar, and go to click any of the inputs, I can't type text in them (the inputs are "Start from an example", "What are you building", and "The brief".
  • aitchnyu 1 hour ago
    Why would somebody ever use a hosted version? I see "One-click gerber, DXF/STEP, render and BOM export" and "Altium support beyond KiCad" in cloud plans, dunno if they are compelling.
  • tylergetsay 2 hours ago
    Can I take the output of this and get a fully assembled board mailed to me? Thats my dream...
    • seidleroni 2 hours ago
      It seems like this is just controlling KiCad. Assuming this produces a BOM as well, you could take the output files, send them to a board house like PCBWay or JLPCB and get the boards stuffed and shipped to you.

      The board houses may have questions for you that may be difficult for you to answer, but theoretically you could answer those with AI and get fully assembled boards delivered right to your doorstep.

      • animeshchouhan 2 hours ago
        not quite. copperhead operates on its own hardware IR, compiles verified KiCad files and generates manufacturing outputs.

        we're also building a design house around it to close the loop with fabs, handle DFM questions and eventually let you hit "order" and receive fully assembled boards!

    • animeshchouhan 2 hours ago
      soon :)

    Has anyone had experience with Copperhead vs Astra and kicad? Looking for a similar tool soon
    • ajnin 2 hours ago
      Copperhead directly edits the KiCad files so that is the CLI version of that Astra demo.
      • animeshchouhan 2 hours ago
        not quite. copperhead operates on its own IR, which then compiles to KiCad files.

      This is what I want to know as well. I'm about to kick off a project or two.
    • animeshchouhan 2 hours ago
      we're developing https://copperbench.org - an open-source benchmark for evaluating ai agents on real, verifiable hardware design tasks.

    With AI enabled consumer hardware usecases going to explode this is something super relevant. At least 5 startups have pitched their wearables to me and they could definitely use this

    "hardware as fast as software". Please no, lol.

    I've imagined a chip running as slow as python.

    • FacelessJim 2 hours ago
      I’ve read it the same way. Definitely a double edged slogan.
    • animeshchouhan 51 minutes ago
      haha nice catch but this is about development speed
    • Joel_Mckay 1 hour ago
      LM555 or 300MB nodejs App on a $300 SoC... the choice is clear... lol =3

    Might be a better website if it wasn't all clearly AI-copy.

    "Nothing commits without its gate."

    • animeshchouhan 1 hour ago
      the website isn't the product. try copperhead and judge the engineering :)
      • hilariously 15 minutes ago
        The website is the marketing for the product, most people see that first, and they wont go further if your front door is festooned with goofball stuff.

    look inside, sees typescript, walks away.

      when LLM calls are the bottleneck, the programming language stops mattering.

    https://github.com/i2cjak/T3CAD seems like another promising project

    I used claude and gemini to edit/debug kicad schematics. And it was pretty good. What is the point of this agent?
    • animeshchouhan 2 hours ago
      copperhead isn't just a wrapper around claude or gpt. it combines model intelligence with its own hardware IR, deterministic engines and continuous verification.
      • j16sdiz 1 hour ago
        User just couldn't care less.

        Do it have extra feature? Speed? Ease of use?

        • animeshchouhan 50 minutes ago
          we have the wrapper orchestrator + additional specialized tools. so yeah we are better than just wrappers.

      Some PM realized that agents will not push back against waterfall style project planning, so now we get an agent for all possible versions of waterfall projects.
      • animeshchouhan 2 hours ago
        fair critique but copperhead works as a feedback loop: design, verify, revise and repeat. closer to an engineering control loop than waterfall with an agent on top :)

          Is it doing any circuit simulation or anything?
          • animeshchouhan 52 minutes ago
            we are building tool plane integrations around the same. stay tuned!
        • toss1 2 hours ago
          When it gets to the end of the design loops, can it run simulations and tests, or is that out of scope i.e., for another product? (I didn't notice testing on a very quick peruse, but that doesn't mean I didn't simply miss it)

      I use a jigsaw to cut wood. It works pretty good. What’s the point of a table saw?
      • mitxela 2 hours ago
        You joke but my coping saw cuts wood much faster than any of my normal saws. I don't know a lot about saws, I presume it's the type of blade on it. And I do indeed have three saws, which is a lot for someone who doesn't know much about saws. One that says it's good for cutting metal, one for wood and one for tight corners in wood (a coping saw).
