It's almost standard to have the USB-C have extra wiggle-room (around 1mm or so). Then, the housing is 1mm past the USB-C connector. That's how the casings are made so that when you stick the connector in, it's flush or nearly so.

I agree with USB extension cables concerns too! The error would increase depending on the quality (impedance, power, etc.)

Thanks! I've been considering it (or enough detailed instructions to build one) since starting the project. I need to get a working model first though ;)

Thank you so much! If you'd like to discuss further, please let me know! My email is in the website. I have a Framework 16 and have tons of ideas. Never got around to it though. (I also burned a few screens, and had 3 as backup haha).

We discussed wave functions, probability, fermions/bosons, did calculations for particle in a box, the Schrödinger model, and went just up to deriving the hydrogen atom. Nothing super fancy, but it was one heck of an experience!

Hey! Thank you for the question. For sure, it's not a polished product and I don't mean for it to be. It works surprisingly well. (I've used it as my daily driver for school) With college apps and school work, the time was tight. I'd say that was the most limiting. Of course, resource and skill played its role. I did consider flex PCBs, but I didn't have the time to follow through with all the ambitions (i also wanted an FOC input sigh).

I'm honored that you think my keyboard implementation is nice! I put a lot of thought into it — truly. Oh btw the keyboard works just as well as a solo device. I've used the keyboard more than the computer in some ways. Thanks!

I'd love to see one; hope to see that day come!!

Truly appreciate it. I spent many weeks afterwards documenting the steps as thoroughly as I could. My email's on the site if anyone needs to reach out, as well. :)

Thank you so much!

Maybe, depending on reception! I geared it so it could be manufactured at a semi-small scale. Unfortunately, I don't have the capacity to make them myself :(. Thank you for the interest!

Thanks for your suggestions and criticism! Much appreciated. Which aspect of it (aside from the SoM, which I admittedly do not have the R&D to make in this timescale) isn't open-source? I'd love to hear your thoughts. The Novena and Reform are amazing pieces of engineering, but I believe they sacrifice the portability and looks for repairability which some people certainly prefer. I wanted to aim for something that a non-technical consumer might look and say "hmm, nice laptop!" and not think it came out of the matrix or built it myself.

In terms of college, still waiting :)

Thanks! Around $300 total from JLCCNC with 6061 aluminum, bead blasting, and matte black anodization (top, midplate, bottom).

Thank you so much!

Thanks for the question. I'm working on compiling the BOM in these few days. A preliminary R&D BOM is here (apologies, it's in Google Sheets): https://docs.google.com/spreadsheets/d/17arbJvPqW6koqEJwAzne...

Hello! We got 5k for the entire robot, and our school does not provide much engineering support. MUREX is entirely student run! Of course, we are incredibly thankful to be able to attend such a great school. we are first this year :)

We didn't try, but I think so. We always ensured the crossovers were correct. Sorry I can't give a better answer!

I agree. They're also so much larger than our design! If getting a switch ever interests you, please let us know at byran@mrx.ee. No pressure of course!

Thanks everyone! Noted deeply in the heart. :)

Thanks! Do it right, do it MUREX!

That's a sick board! If we had found that before we made it, maybe would have just used this board haha. What is "buy-in"? Is it meaning us using JLCPCB to buy and assemble the chips?

For sure, this wasn't that hard. But I think that's great; it means anybody can be an EE. That's a core mission of our team. Our team works hard on PCIe 4.0, USB 3.1 Gen 1, and Gigabit ethernet as well. This is just one board that we made and were proud of. Feel free to take a look at our other boards in the documentation website!

unleashing innovation :o

That would be super cool! I'm not sure how it'd work together. I would think we need a higher speed fabric-type connection.

Thank you! Noted.

Thank you!

You can buy them right of Digikey by searching "4 position Molex Picoblade cable assemblies" or similar!

Hello! It supports 100Mb throughput, nothing more, nothing less. It's been tested with iperf. I believe it switches at line rate, but don't quote me on that haha. The chip's extra features can be enabled with an EEPROM, which we removed to cut costs and size further. It's on V1 though.

We only found ~gigabit and ~fast ethernet chipsets that are easily accessible. However, it's definitely something we will think about in the future! Thanks for the suggestion!

Unfortunately, it's not really useful for our use-case. Our robot only uses ~kB amount bandwidth.

That’s one area we are exploring!

Thank you! We also have those switches. They are fantastic cheap tech as well.
