Over the years, we’ve figured out some pretty sure-fire ways to get hackers and makers motivated for contests. One of the best ways is to put arbitrary limits on different aspects of the project, such as how large it can be or how many power it can consume. Don’t believe us? Then just take a […]
You normally don’t think a lot would go into the construction of a chair. However, when that chair is attached to a commercial jet plane, there’s a lot of technology that goes into making sure they are safe. According to a recent BBC article, testing involves crash dummies and robot arms. Admittedly, these are first-class […]
Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and rocks whizz around. In the same way that a catfish doesn’t much care what’s going on above the surface […]
A little under 25 years ago, a particularly bizarre game was released for Sega’s Dreamcast. In actually, calling it a “game” might be something of a stretch. It was more of a pet simulator, where you need to feed and care for a virtual animal as it grows. Except rather than something like a dog […]
If you cut your teeth on Z-80 assembly and have dabbled in other assembly languages, you might not find much mystery in creating programs using the next best thing to machine code. However, if you have only used high level languages, assembly can be somewhat daunting. [Shikaan] has an introductory article aimed to get you […]
The dulcet tones of a modem handshake may be a thing of the distant past for most of us, but that hasn’t stopped there being a lively hacking scene in the world of analogue telephones. Often that’s achieved using old devices resurrected from a parts bin, but sometimes, as with [Brian]’s USB modem, the devices […]
Although battery fires in electric cars and two-wheeled vehicles are not a common phenomenon, they are notoriously hard to put out, requiring special training and equipment by firefighters. Although the full scope of the issue is part of a contentious debate, [Aarian Marshall] over at Wired recently wrote an article about how the electric car industry […]
For as useful as computers are in the modern ham shack, they also tend to be a strong source of unwanted radio frequency interference. Common wisdom says applying a few ferrite beads to things like Ethernet cables will help, but does that really work? It surely appears to, for the most part at least, according […]
We’ve previously covered the PiEEG, an affordable brain-computer interface (BCI) shield designed to connect to the Raspberry Pi. The open source project developed by [Ildar Rakhmatulin] is intended to allow students and hobbyists to experiment with detecting electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG) biosignals — unlocking a wide array of applications ranging from assistive […]
In a world that has no shortage of macropads, the duckyPad still managed to set itself apart. The open source mechanical pad offered an incredible array of customization options, and thanks to its onboard OLED display, you never had to wonder which key did what. But there’s always room for improvement. Announced earlier today, the […]
