When it has become so common for movies and television to hyper-sensationalize engineering, and to just plain get things wrong, here’s a breathe of fresh air. There’s a Sci-Fi show out …

How do you feel about Jello? It’s alright tasting, but it’s much more about how jiggly it gets. Nobody — probably — would eat Jello if it was a hard candy. It would quickly …

With more and more embedded systems being connected, sending state information from one machine to another has become more common. However, sending large packets of data around on the network can b…

A big part of the Hackaday Prize this year is robotics modules, and already we’ve seen a lot of projects adding intelligence to motors. Whether that’s current sensing, RPM feedback, PID…

Consider the piggy bank. Behind that innocent, docile expression is a capitalistic metaphor waiting to ruin your fond memories of saving for that BMX bike or whatever else it was that drove home th…

Makerbot 3D printers were among the first to hit the market, so it makes sense that old and broken ones now litter the shelves of hackerspaces and home workshops alike. Rather than throw his one ou…

The GOES-R series of Earth observation satellites are the latest and greatest NASA has to offer. As you might expect, part of the GOES-R job description is imaging Earth at high-resolution, but the…

In Northern England, the hills used to be home to steam trains. The trains have long faded into history, but the sound of their whistle is making a brief return. Artist [Steve Messam] has created &…

Do you need a bias tee? If you want to put a DC voltage on top of an RF signal, chances are that you do. But what exactly are bias tees, and how do they work? If that’s your question, [W2AEW]…

It’s said that the electronic devices we use on a daily basis, particularly cell phones, could be so much smaller than they are if only the humans they’re designed for weren’t so …

Almost every project of mine from the last quarter century, if it has contained any wiring, has featured somewhere at least one crimp connector. There are a multiplicity of different types of crimp…

In 2012, [Bruno] wanted to detect some bats. Detect bats? Some varieties of bat (primarily the descriptively named “microbats”) locate themselves and their prey in space using echolocat…

Whether you are young, old, or a time traveling Vulcan, something unites all of us globally: the innocent LEGO blocks that encourage creativity over spoon-fed entertainment. Have you noticed the ex…

The world — and the Hackaday Prize — is filled with educational robots. These are small, wheeled robots loaded up with sensors, actuators, a few motor drivers, and some sort of system t…

What do you do when you suddenly find you have some free time because you’re waiting on parts or have run up against other delays for your current project? If you’re [James Bruton], you…

Maybe it’s the silly season of high summer, or maybe a PR bunny at a cybersecurity company has simply hit the jackpot with a story syndicated by the Press Association, but the non-tech media …

Have you ever heard the old axiom that if you want to design a simple system, ask yourself if your grandmother could use it? Maybe that was on Wired’s mind because they asked a quantum comput…

If you’re tired of having to make small talk with random people in the office break room every time you need a cup of coffee, or simply don’t have the time to get up to pour yourself so…

In 1976, Texas Instruments came out with the TL084, a four JFET op-amp IC each with similar circuitry to Fairchild’s very popular single op-amp 741. But even though the 741 has been covered i…

Many readers will be familiar with the TS100 soldering iron, a lightweight and powerful tool with an integrated temperature controller in its handle based upon an STM32 microcontroller. As an iron …
