A new mini PC equipped with 6 Gigabit Ethernet ports has been recently launched powered by an Intel Core i5-1135G7 processor

Homebrew Network Card With No CPU

A modern normal network card will have onboard an Ethernet controller which, of course, is a pre-programmed microcontroller. Not only does it do the things required to keep a computer on the networ…

How DEC’s LANBridge 100 Gave Ethernet A Fighting Chance

When Ethernet was originally envisioned, it would use a common, shared medium (the ‘Ether’ part), with transmitting and collision resolution handled by the carrier sense multiple access…

Ethernet For Hackers: Transformers, MACs And PHYs

We’ve talked about Ethernet basics, and we’ve talked about equipment you will find with Ethernet. However, that’s obviously not all – you also need to know how to add Ethern…

Restoring Starlink’s Missing Ethernet Ports

Internet connectivity in remote areas can be a challenge, but recently SpaceX’s Starlink has emerged as a viable solution for many spots on the globe — including the Ukrainian frontline…

Ethernet For Hackers: Equipment Exploration

Last time, we talked about the surface-level details of Ethernet. They are fundamental to know for Ethernet hacking, but they’re also easy to pick up from bits and pieces online, or just from…

Underwater Sensor Takes Single Pair Ethernet For A Dip

The 10BASE-T1 Ethernet standard is also known as ‘single pair Ethernet’ (SPE), as it’s most defining feature is the ability to work over a single pair of conductors. Being fairly …

Ethernet For Hackers: The Very Basics

Ethernet is ubiquitous, fast, and simple. You only need two diffpairs (four wires) to establish a 100Mbit link, the hardware is everywhere, you can do Ethernet over long distances easily, and tons …

New BeagleV-Fire features FPGA and RISC-V CPU and is available now around $150. Credit-card sized, Linux-enabled board based on Microchip Polarfire SoC offers high-speed I/O with BeagleBone cape compatible headers and SYZYGY and M.2 connectors.

Adapter Board Expands The Pi Zero

The standard Raspberry Pi computers have been in short supply for a while now, so much so that people are going to great lengths to find replacements. Whether it’s migrating to alternative si…

Send This FPV Bot Into The Crawlspace To Do Your Dirty Work

The least pleasant space in most houses is likely to be the space below it. Basements tend to be dank, dusty, and full of too many things that have too many legs. And even worse than the full basem…

It’s Ethernet, From An SPI Interface

Over the years as microcontrollers have become fast enough to do the heavy lifting, we have become used to 10 megabit Ethernet being bit-banged from interfaces it was never meant to emerge from. We…

Power Over Ethernet, Explained

Most readers will be familiar with Ethernet networks in some form, in particular the Cat5 cables which may snake around the back of our benches. In a similar vein, we’ll have used power over …

Bit-Banging Bidirectional Ethernet On A Pi Pico

These days, even really cheap microcontroller boards have options that will give you ethernet or wifi access. But what if you have an original Raspberry Pi Pico board and you really want to MacGyve…
