We made a small and cheap network switch

Hello, we're Max and Byran from MUREX Robotics, a high school robotics team from Exeter, New Hampshire. We are super proud to have made this open source piece of technology! It is only 6.9 dollars (actually!) from JLCPCB :) I hope you like it. You can find us at [email protected] and [email protected] as well if you have any questions. We will be putting a small run of these boards for sale somewhere (we have <25 units of stock), probably for $10+shipping. Let us know if you're interested in more! Board files for everything we make is here:…

We made a small and cheap network switch launched on June 16, 2024 with 666 votes, #29 of 4,672 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 2 years on.

In plain words

MUREX Robotics, a high school team from Exeter, New Hampshire, created an open-source network switch designed to be affordable and compact. The switch costs $6.90 to manufacture and is available in limited quantities for approximately $10 plus shipping. Complete board design files are open source and accessible on GitHub, making it suitable for robotics projects, makers, and developers seeking an inexpensive networking solution. The team welcomes inquiries about purchasing or technical questions.

From the sources

Attempt the impossible. This is MUREX Robotics.

The mrxSwitch is the world's smallest and cheapest networking switch, in addition to being fully open-source. With the focus on simplicity and cost, the MUREX Ethernet Switch utilizes external magnetics, a high performance unmanaged switch IC, and 1.25mm pitch Fast Ethernet (100BASE-TX) connectors. The MUREX Ethernet Switch, or mrxSwitch, is a 5 port 100BASE-TX unmanaged switch using the IP175Gx Ethernet Integrated Switch IC. mrxSwitch steps down an input up to 15V down to its operating voltage of 3.3V. Designed with a four layer board for minimal noise, the mrxSwitch has full Bob-Smith style termination for all center taps and calculated differential pairs of 100Ω. The switch utilizes 10…from docs.murexrobotics.com

    Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link. Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main…

  • Dobb·E – towards home robots with an open-source platform2023 · dobb-e.com · ▲394

    Hi HN! Proud to share our open-source robot platform, Dobb·E, a home robot system that needs just 5 minutes of human teaching to learn new tasks. We've already taken Dobb·E to 10 different homes in New York, taught it 100+ tasks, and we are just getting started! I would love to hear your thoughts about this. Here are some more details, below (or see a Twitter thread with attached media: https:&#x2F;&#x2F;twitter.com&#x2F;i&#x2F;status&#x2F;1729515379892826211 or https:&#x2F;&#x2F;nitter.net&#x2F;i&#x2F;status&#x2F;1729515379892826211): We engineered Dobb·E to maximize efficiency, safety, and…

    Hi HN, we build an open-source operating system extension for orchestrating robot swarms fully decentralized. This first beta version allows you to create fully decentralized robot swarms. The system will set up a wireless mesh network and run a p2p networking stack on top of it, such that nodes can interact with each other through various abstractions using our SDKs (Rust, Python, TypeScript) or a CLI. We hope this is a step toward better inter-robot communication (and a fun project if you have a few Raspberry Pis lying around). Our mesh network is created by B.A.T.M.A.N.-adv and we’ve…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
