You’ve got to love the aesthetics of dystopian cyberpunk video games, where all the technology looks like it’s cobbled together from cast-off bits of the old world’s remains. Kudos go to those who attempt to recreate these virtual props and bring them into the real world, but our highest praise goes to those who not […]

The official Arduino team has this week announced that support for its latest microcontroller the UNO R4 WiFi has now arrived in the Arduino Cloud. The integration of UNO R4 WiFi support in the Arduino Cloud is a significant development that offers makers enhanced features and seamless connectivity. Whether you’re a beginner or an expert, this development will undoubtedly

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers that work in much the same way. [mircemk] decided to whip up a digital compass to demonstrate the value of these parts. The build uses
Everyone wants a wider field of view in their VR headsets, but that’s not an easy nut to crack. [Statonwest] shows there’s a way to get at least some of the immersion benefits with a bit of simple hardware thanks to the VR Ambilight. A few years ago the Ambilight showed up as a way to spice up TV

While the Fourier transform gets all the attention, there are other transforms that engineers and mathematicians use to transform signals from one form to another. Sometimes you use a transform to make a signal more amenable to analysis. Other times, you do it because you want to manipulate it, and the transform is easier to
Thomas Edison once said that genius was 1% inspiration and 99% perspiration. That doesn’t leave much room for partspiration. I’m working on a top-secret project, and had to place a parts order on AliExpress with a minimum order quantity of five in order to get decent shipping times. No big deal, financially, and it’s always great
When it comes to voice assistant devices, the Amazon Echo, boasting the ever-ready Alexa, has won the hearts of millions worldwide with its impressive functionalities. However, let’s be honest, while these devices score high on practicality, they lack the flair and personality that would truly bring them to life. Well, there’s some good news for
Amazon Echo transformed into animatronic robot Continue Reading
Back in 2020, students from Universidad Del Valle De Guatemala (UVG) pulled off a really impressive feat, designing and building a CubeSat that lasted a whopping 211 days in orbit. In addition to telemetry and radio equipment, it carried a black-and-white camera payload. But it turns out space is hard. The first pictures were solid black or
In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting for an altogether simpler desktop fire control solution. This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts. To supply targeting data

Having a computer that locks its screen after a few minutes of inactivity is always a good idea from a security standpoint, especially in offices where there is a lot of foot traffic. Even the five- or ten-minute activity timers that are set on most workstations aren’t really perfect solutions. While ideally in these situations
