Initially only seeing brief popular use as the filament in incandescent lighting, carbon fibers (CF) experienced a resurgence during the 20th century as part of composite materials that are lighter and stronger than materials like steel and aluminium, for use in aircraft, boats and countless more applications. This rising popularity has also meant that the […]
If you’d like to measure the speed of your cycling then it’s easy enough to buy a cycle computer, but as [Clovis Fritzen] has done it’s also an option to build one. The result of his work is a smart PCB on which the speed is indicated with a row of LEDs. The sensor is […]
You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a testament to that. In particular, I2C is such a powerful standard, it’s nigh omnipresent – if you were to […]
Even if you don’t like to build replicas of movie robots, you can often draw inspiration from cinema. Everyone knows Robby the Robot, Gort, and R2D2. But [Atomic Snack Bar] treats us to some lesser-known robots from movies in the 1930s, 40s, and 50s. While we are pretty up on movies, we have to admit […]
Even though we somewhat uncharacteristically don’t have a cyberdeck contest currently underway, there’s never a bad time to get your [Gibson] on. That’s especially true when fate hands you an enclosure as perfect as the one that inspired this very compact Kali Linux cyberdeck. Now, that’s not to say that we don’t love larger cyberdecks, […]
Cats are notorious for interrupting workflow. Whether it’s in the kitchen, the garden, or the computer, any feline companion around has a way of getting into mischief in an oftentimes disruptive way. [Robin] has two cats, and while they like to sit on his desk, they have a tendency to interrupt his mouse movements while […]
String instruments have a long history in civilization, helping humans make more complex and beautiful music. We wonder what our forebears would think of this guitar strummed with 1000 picks? [Mattias Krantz] wondered what the best number of picks was to play guitar and took the experiment to its illogical extreme. Starting with zero picks […]
In the late 1800s, the stereograph — sometimes incorrectly called a stereopticon — was a big craze. You’d view two side-by-side images through some lenses and see a three-dimensional image. This, of course, later would morph into View-Masters and, eventually, virtual reality headsets. But if you have an old stereograph, where do you get new […]
Remote-controlled cars can get incredibly fast and complex (and expensive) the farther into the hobby you get. So much so that a lot of things that are missing from the experience of driving a real car start to make a meaningful impact. [Indeterminate Design] has a few cars like this which are so fast that […]
