    Meta comment: nice to see someone NOT putting their FOSS project on Microslop (GitHub) and using another platform for hosting their code. I respect that, thank you for standing up to GitHub's dominance. I wish more projects didn't give GitHub such monopoly power by defaulting to using it.

      Meta comment to your meta comment : this is a very personal opinion but I cannot stop myself from thinking less about your message (even though I agree with it), just because of that edgy wannabe way to go about naming Microsoft. You want to say Microsoft say that, you want to say Github say that but if you say a vaguely insulting name only to have to specify what you actually mean... It doesn't bring anything to the conversation, except lower the level, and if a company has flaws as big as Microsoft you don't need to resort to childish name calling to expose them. This is my personal opinion.

        won’t somebody please think of the billion dollar company?

        • nolok 2 hours ago

          This has nothing to do with the billion dollar company, and I have no lost love for Microsoft.

          It's about quality of discourse among us, and Microsoft has nothing to do with that.

        It means GH is now full of slop and pointing out it's owned by Microsoft, for those who may not have known or LMS who did not until recently

    Interesting that Gemini said it was infeasible. It should be aware that using a Pico W as a transparent ethernet bridge has been done several times over in open source projects, for example on BlueSCSI (emulating a Daynaport SCSI-Ethernet adapter) and PicoMEM and my own PicoGUS project (emulating an NE2000 Ethernet adapter).

    • tehlike 3 hours ago

      It's often good to approach what llm said as a guidance, and not as ground truth.

      You can ask follow up questions or point to potential feasibility and it will change its answer.

      • bookofjoe 35 minutes ago

        Yes, but. I asked Perplexity Pro the same fact question (sports) three days in a row after correcting its error the first day and having the correction acknowledged with a promise to get it right in the future. Same error on second day, same promise. Third day: correct. Perhaps it needs to be in the "Slow" classroom....

          It is "grounded in reality" and changes its answer like the weather.

            No, Claude, etm are for "Entertainment purposes only", as listed in their TOS.

            You know, like the same for horoscopes and psychics.

    • byb 5 hours ago

      Exactly, bit banging an 8-bit bus isn't that different from pushing the data out of the USB port. It would be great to try an LLM trained on pre-1900 documents and ask it if powered flight is possible.

      Great work on PicoGUS.

    • alexjurkiewicz 3 hours ago

      It was Gemini Flash, probably an even faster variant optimised for immediate response on search pages.

    • rvz 3 hours ago

      > Interesting that Gemini said it was infeasible.

      Unless there is a hardware limitation or the hardware does not support it, anything in software is possible.

      Gemini and all these other LLMs are designed to convince you that they have "awareness" which they do not have any of the sort. They are neither sentient nor do they have consciousness

      • whywhywhywhy an hour ago

        Something doesn’t have to be sentient or have consciousness to answer a technical question like that.

      • dTal 2 hours ago

        Bad take. Some things are feasible and some things are not, "anything is possible" is a useless framework. Example: go convert two smartphones to communicate p2p over their 4g radios - it's all software!

        LLM "awareness" is similarly irrelevant. They process information usefully, in a way grounded in reality, and that's that.

        • rvz 31 minutes ago

          You seem to be all over the place, most of it by not reading the parent's comment. So let's break it all down.

          > Bad take. Some things are feasible and some things are not, "anything is possible" is a useless framework.

          It would help if you quoted the entire comment rather than removing the context and further giving a very bad example afterwards:

          > Example: go convert two smartphones to communicate p2p over their 4g radios - it's all software!

          Nice try. That is a hardware limitation in the 4G radio which is designed to connect to an operator mast. Even if you wanted to do it in software, the hardware does not support that P2P use-case which is what I already said.

          > LLM "awareness" is similarly irrelevant.

          Exactly. There is no such thing as awareness in LLMs.

          The parent comment I replied to believed that an element of awareness had to be present to give an answer because this was done "several times over" in open source projects. Which that is inaccurate in the context of LLM research.

          >> "It should be aware that using a Pico W as a transparent ethernet bridge has been done several times over in open source projects..."

          > They process information usefully, in a way grounded in reality, and that's that.

          Useful to those who know when it is either mostly correct or outright wrong.

          Clearly in this example, Gemini doesn't even know if its own answers are grounded in reality and consequently people using them are unable to determine if the results they bring are true or not and there are countless examples of that.

          So you know what you just said is not true.

    Interesting project.

    In a similar but opposite vein, I am going on a vacation and I wanted to share the stupidly expensive internet in my room at night with the family so I am likely bringing a raspberry pi to have as a travel router attached to my Mac. In this case, I can use the RaspAP project: https://raspap.com/

    This is slightly different in that I do want a NAT.

    • Tepix 44 minutes ago

      It's also slightly different because this project is for the Pi Pico.

      • bhouston 31 minutes ago

        Yeah, given the through put on the Pico is just 4Mbps in this setup, it will not work as a travel router for the family.

  • KJs6ZxELzQM37O 2 hours ago

    I recently bought Pico 2 W for DualSense (https://github.com/awalol/DS5Dongle).

    pico-usb-wifi is firmware for the Raspberry Pi Pico W that turns it into a driverless USB Wi-Fi adapter, enumerating as a USB CDC-NCM device.

    > Average 4.75 Mbits/sec throughput

    Isn't that slow for WiFi?

    I mean it's an interesting learning experience, but isn't that strictly worse than pretty much any WiFi dongle?

    • tehlike 3 hours ago

      Yes, the guy clearly spent more of his time than it's worth - you can buy a wifi dongle for a few bucks on aliexpress.

      But that's exactly the point of such experience. It's a challenge, and the guy/gal nailed it.

      • bhouston 30 minutes ago

        You can not buy wifi usb adapters that work with MacOS on MacBooks I believe. I could be wrong but I think none of them have driver support.

      • moffkalast an hour ago

        Well Claude nailed it, but they get credit for the idea.

          Yes, just yesterday I got codex to write me a home assistant plugin for reticulum lxmf. For the fun of it. It got things wrong, I got it to fix.

    • teaearlgraycold 3 hours ago

      The Pico is USB 1.1, so the upper bound is 12 Mb/s.

  • drop-volley 7 hours ago

    Can you have the Pico operate as an access point? Would love to be able to use this to connect over wifi to a printer (printer in client mode), with the printer and macos talking directly over IP without needing to configure any other routing/forwarding on macos.

    • bdcravens 7 hours ago

      Wifi printer, where both your machine and the printer are connected to the same AP? yes

      If you'd rather just expose a USB printer to the network, a Pi Zero is a better fit.

    • teaearlgraycold 3 hours ago

      The Pico W can host an AP.

  • hellweaver666 5 hours ago

    Oooooh, now I'm thinking... you could design a simple circuitboard that holds multiple picos (surface mounted) and uses the USB data pads on the back to pull all the USB ports out to an onboard USB hub basically allowing you to add a multitude of wifi adapters to a project in one USB cable. Would be great for War Driving!

  • vardump 5 hours ago

    Thanks! Now I potentially have ~20 USB WiFi adapters I didn’t have yesterday.

    Even better, no need to hassle with the WiFi settings on the target system.

    In wrong hands, Pico W is actually a bit terrifying device, because it combines USB and wireless.

      It's one of the neat features of the AsciiDoc language. The user is able to change captions mid document, in this case :figure-caption:. AsciiDoc and Antora are things I've invested a lot of my time into

    • MgB2 3 hours ago

      I'm kind of fascinated by the first diagram on the page. It sits so firmly in the uncanny valley for me and I can't put my finger on why. By itself every part looks ok and normal, but as a whole it just screams AI to me. I don't know if its the color choices or the composition or something else. It all just feels that little bit off.

      I mean, I know its AI, the page says so itself, no one is trying to hide it. But it also just gives me AI vibes on such a subliminal level that I can't figure out why.

      • Tepix 39 minutes ago

        It's the amount of little icons and bold text. And then phrases like "No NAT, No Port-forwards"

        Also details like the light blue boxes being swapped.

      • kalleboo an hour ago

        To me there's something about the "AI Slop Font" where it instantly triggers that uncanny valley. I guess since it's kind of an average of a bunch of fonts so it's somehow familiar but also unfamiliar at the same time.

      • mhl47 an hour ago

        Absolutely can relate. Thats why I would say: Do your own diagrams! At least the text and formatting.

        Where I do think it ads value is "AI slop 2". This is somehow even better comprehensible than an average photo.

    • Tepix an hour ago

      The pic "AI Slop 2. A Real World Situation" is great, the USB cable is connected to the wrong end of the Pico!

    Google Gemini is that naysayer senior developer who confidently tells you it can’t be done.

    Claude is that easy to get along with smart hard working guy who just gets on with it and builds it double quick.

    ChatGPT is the eager senior developer who says it can be done but can’t actually work it out and fluffs it.

    • lionkor 4 hours ago

      Actually, all of them are fallible, very incompetent machines that are good at writing text. They're not people, they don't have any qualities of people except the really bad ones, and they are absolutely miserable at reasoning.

      The only people I know who use Gemini are unemployed.

      The only people I know who use Claude vibe-code everything, often including their communication -- they probably let Claude kiss their kids goodnight.

      Everyone else uses ChatGPT, and the world is worse off for it.

      They are machines. "it" is the only acceptable pronoun, and personifying these machines adds emotion into the discussion and the use of the tool. They are not people. They do not behave like people. If you feel like they do, and you're e.g. autistic, that's entirely fair, so please take my word that they do not behave sufficiently like people in any way.

      Nothing they do mirrors the behavior of engineers. They instead mimic the language of engineers. I understand that this is all it takes in a lot of circles to gain respect, which is quite a sad state for those circles, but that doesn't mean its a universal experience.

      • type0 25 minutes ago

        > Everyone else uses ChatGPT

        I'm actually tired that people put stupid questions in ChatGPT and then present in with a straight face as a source of truth. Sometimes it hallucinates completely, sometimes the conditions or regulation have changed and it gives false answers and no-one cares. Simple collaborations that was possible before now turn into unnecessary arguing. Some ChatGPT users aren't even aware that LLMs hallucinate, I just pointed it out recently and was accused of mansplaining and being a tinfoil hat.

        > Nothing they do mirrors ...

        "Mirror, mirror on the wall, who is the fairest of them all?"

    • mechazawa 5 hours ago

      Gemini writes pretty shitty code in my experience. We tried it out for a grand total of half a day at work before deciding it wasn't worth our time and switched back to Opus.

      ChatGPT writes like it's life depends on it and refuses to correct its own mistakes. It'll figure out a way to write 4k lines for something that could've been done in 500

    > I spent two days of a long holiday weekend and about one million Claude Code tokens building this firmware.

  • GL26 6 hours ago

    one million Claude Tokens (assuming you are on opus) = 5 USD = the very dongle you tried to replace. Add the cost of the rasberry pico, you'll have an easier time buying the wifi dongle. The project is cool thought to learn about networks, NAT, Proxys, ect...

    • byb 5 hours ago

      No, it's not really easier to buy a Wi-Fi dongle. My target device is the Spotify Car Thing and SuperBird doesn't have Wi-Fi components. My Claude Code Pro subscription was idle, so it cost me nothing. Also, according to an article from Tom's Hardware from two years ago, four million Picos have already shipped, so I've unlocked this ability for let's say 500,000 devices. Finally, my day job is in the Wi-Fi industry... this wasn't a learning exercise.

    • farfatched 4 hours ago

      The author's tone when they discuss the cost of the project is self-deprecating. They know it would have been simpler to just buy one.

      But also, the author has given the community a great gift, both directly (the blog post and the project!) and indirectly (the idea: what else can be implemented in similar ways).

    • bdavbdav 5 hours ago

      It’s nice that it doesn’t need the WiFi stack or host side configuration though. This would be great for headless machines.
