Turn your lights on and off by staring at this little robotic switch
Reading Time: 2 minutesUnlike every other hands-free light switch that relies on infrared motion detection or changes in ambient light values, Michael Rigsby’s “Look at Me Light Switch” instead requires a person to stare at it for six seconds. Based on an embedded machine learning model and a microcontroller, this device uses Person Sensor from Useful Sensors,…

Predicting when a fan fail by listening to it
Reading Time: 2 minutesEmbedded audio classification is a very powerful tool when it comes to predictive maintenance, as a wide variety of sounds can be distinguished as either normal or harmful several times per second automatically and reliably. To demonstrate how this pattern recognition could be incorporated into a commercial setting, Kevin Richmond created the Listen Up…

Get More Out of Your Smartphone with Arduino
Reading Time: 5 minutesOur smartphones go pretty much everywhere with us, and we use them for more things than we even realize. From literally the very moment we’re startled into life in the morning, until the one final doom scroll through social media before bed, our phones are with us. It makes sense, then, to…

The Periodic Table Clock oozes nerdy charm
Reading Time: 2 minutesThe periodic table is arguably the most popular symbol of nerd pride. Everyone knows what it is, but few people are familiar enough with it to make real use of it. There aren’t, for instance, many people that can tell you the atomic number of darmstadtium. If you’re one of the nerdy…

This illuminated chessboard displays possible moves
Reading Time: 2 minutesChess is a tricky game to learn, even before you get into various strategies and tactics. The simple act of memorizing the different piece’s moves can be overwhelming to people new to the game. To make it easy to determine where pieces can go, Redditor Bakedbananas is building an illuminated chess board…

Recreating a century-old Argentinian rainmaking machine
Reading Time: 2 minutesYou’ve heard about the many different snake oil concoctions shilled by con men over the centuries, but did you know that inventors created a variety of machines for similar purposes? The most well-known example is probably the belt vibrator, which purported to induce weight loss. In Argentina during the 1930s, Juan Baigorri…

Self-guided circular saw automates woodworking
Reading Time: 2 minutesA circular saw is a must-have tool for anyone who wants to do even basic woodworking. But getting clean, straight cuts is a skill that takes practice to develop. To automate the process in order to perform clean cuts every time with zero effort, Red Tie Projects created this self-guided circular saw.…

Time Slider is an interesting spin on clock design
Reading Time: 1 minuteYou can build a simple and accurate clock with any Arduino board, an RTC (real-time clock) module, and a four-digit seven-segment display. But if you want to be inspired by a more unique design, check out Hans Andersson’s Time Slider. This clever clock features four sliders — one for each digit of…

Controlling a robot arm over the internet
Reading Time: 2 minutesFor those with an interest in robotics, there is little in this world more enticing than a robot arm. A rover may be able to drive around, but so can a cheap RC car. A robot arm, on the other hand, can do real work, like stacking blocks or moving colored balls…

Digital barometer channels vintage aesthetics
Reading Time: < 1 minuteThere are many reasons why you might want to know the local barometric pressure. Maybe you do long-range target shooting and want to know how it will affect your ballistic trajectory. Or maybe you want to evaluate the performance of an internal combustion engine. To find that information, you’ll need a…

Controlling a model railroad with a vintage Atari ST
Reading Time: 2 minutesBack in the ’90s, Cyril Rossignol had a dream of controlling his model railroad with his computer. While that was possible at the time, it wasn’t easy and would have required some serious skill with hardware and programming. But today, thanks to development boards like those from Arduino, this is a much…

A DIY peristaltic pump controlled by an Arduino
Reading Time: 2 minutesThere are many different fluid pumping mechanisms to choose from, but the peristaltic pump is a great choice when you don’t want the liquid to contact any moving parts. That is ideal for beverage dispensers and medical equipment, because the liquid only touches the tube it runs through and that is easy…

Detecting falls by embedding ML into clothing
Reading Time: 2 minutesBone density, strength, and coordination all decrease as we age, and this fact can lead to some serious consequences in the form of slips, falls, and other accidents. In Finland, falling is the most common type of accidental death among those age 65 and over, amounting to around 1,200 per year. But…

James Bruton improves his triangle-tracked tank
Reading Time: 2 minutesTanks are already quite maneuverable, because the tracks allow them to rotate in place. But what if they were even more maneuverable and could drive in any direction? About a year ago, James Bruton built a small robot tank that had that capability thanks to a triangle-shaped track system with omniwheel-style rollers.…

This little robot helps fight fires
Reading Time: 2 minutesFirefighting is a dangerous profession, but it is possible to mitigate some of that danger with good data. When firefighters entered a burning building, their biggest fear is the unknown. They don’t know if they can trust the structural integrity of the building, if there is a pocket of toxic or explosive…
