Sometimes, all it takes is looking at an existing piece of tech in a new way to come up with something unique. That’s the whole idea behind FallingWater, a gorgeous Art Deco inspired clock created by [Mark Wilson] — while the vertical LCD might look like some wild custom component, it’s simply a common DM8BA10 […]
Among the current challenges with creating quantum computers is that the timespan that a singular qubit remains coherent is quite limited, restricting their usefulness. Usually such qubits consist of an electromagnetic resonator (boson), which have the advantage of possessing discrete energy states that lend themselves well to the anharmonicity required for qubits. Using mechanical resonators […]
If you’ve ever worked with adding lithium-ion batteries to one of your projects, you’ve likely spent some quality time with a TP4056. Whether you implemented the circuit yourself, or took the easy way out and picked up one of the dirt cheap modules available online, the battery management IC is simple to work with and […]
When you think of making something using a lathe,  you usually think of turning a screw, a table leg, or a toothpick. [Uri Tuchman] had a different idea. He wanted to make a clock out of the gears used in the lathe. Can he do it? Of course, as you can see in the video […]
Many things have combined to make very high-frequency RF gear much more common, cheaper, and better performing. Case in point: [dereksgc] is tearing apart a 20 GHz low-noise block (LNB). An LNB is a downconverter, and this one is used for some Irish satellite TV services. The scale of everything matters when your wavelength is […]
Alfred Vail (public domain) We talk about Morse code, named after its inventor, Samuel Morse. However, maybe we should call it Vail code after Alfred Vail, who may be its real inventor. Haven’t heard of him? You aren’t alone. Yet he was behind the first telegraph key and improved other parts of the fledgling telegraph […]
LEGO bricks might look simplistic, but did you know there’s an actual science behind their sizes? Enter LDUs — LEGO Draw Units — the minuscule measurement standard that allows those tiny interlocking pieces to fit together seamlessly. In a recent video [Brick Sculpt] breaks down this fascinating topic. So, what is an LDU precisely? It’s […]
We’re covering two weeks of news today, which is handy, because the week between Christmas and New Years is always a bit slow. And up first is the inevitable problem with digital license plates. Unless very carefully designed to be bulletproof, they can be jailbroken, and the displayed number can be changed. And the Reviver […]
When you think of languages you might read about on Hackaday, COBOL probably isn’t one of them. The language is often considered mostly for business applications and legacy ones, at that. The thing is, there are a lot of legacy business applications out there, so there is still plenty of COBOL. Not only is it […]
Do you ever have clothes that you only wore for a few hours, so you don’t want to wash them, but it still seems icky to put them back in the drawer or closet? What if you had a dedicated place to put them instead of on your floor or piled on a chair in […]
