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 The post Self-guided circular saw automates woodworking appeared first on Arduino Blog.

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 contains four sliders — one for each digit of the time. Those The post Time Slider is an interesting spin on clock design appeared first on Arduino Blog.

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 The post Controlling a robot arm over the internet appeared first on Arduino Blog.

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 The post Digital barometer channels vintage aesthetics appeared first on Arduino Blog.

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. The post Controlling a model railroad with a vintage Atari ST appeared first on Arduino Blog.

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 The post A DIY peristaltic pump controlled by an Arduino appeared first on Arduino Blog.

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 The post Detecting falls by embedding ML into clothing appeared first on Arduino Blog.

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 The post James Bruton improves his triangle-tracked tank appeared first on Arduino Blog.

Firefighting 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 gas, or how The post This little robot helps fight fires appeared first on Arduino Blog.

VFDs (vacuum fluorescent displays) were common a few decades ago and have a nice, distinct glow that many find appealing. But like Nixie tubes and CRTs, VFDs have are outdated and almost obsolete at this point. They can’t come close to matching the price or functionality of modern LCD and OLED screens, but they still The post This original video game console features a VFD appeared first on Arduino Blog.
