Chess 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 that displays a […]
You’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 Velar claimed to […]
A 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. This is exactly […]
You 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 the time. Those […]
For 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 from one bin […]
There 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 barometer like this digital […]
Back 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 more accessible project. […]
There 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 to clean or […]
Bone 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 Thomas Vikstrom hopes […]
Tanks 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. But it had […]
