Controlling a bionic hand with tinyML keyword spotting
Reading Time: 2 minutesArduino Team — August 31st, 2022 Traditional methods of sending movement commands to prosthetic devices often include electromyography (reading electrical signals from muscles) or simple Bluetooth modules. But in this project, Ex Machina has developed an alternative strategy that enables users to utilize voice commands and perform various gestures accordingly. The hand itself was made…

Monitoring the force of a 20-ton hydraulic press
Reading Time: 2 minutesArduino Team — August 29th, 2022 Material testing often comes down to breaking stuff and measuring how much force it took to do so. How a thing breaks is a result of different strength properties. There are many different types of strength, but mechanical engineers are most concerned with tensile, compressive, shear,…

Classic Macintosh gets a massive ePaper display
Reading Time: 2 minutesArduino Team — August 24th, 2022 The original Apple Macintosh computer, launched in 1984, was fundamental for ushering in GUIs (graphical user interfaces). It wasn’t the first personal computer to feature a GUI operating system and the concurrent Apple II still retained a more traditional command line interface for years, but we…

An Arduino controls this strange two-wheel steering e-bike
Reading Time: 2 minutesArduino Team — August 24th, 2022 James Bruton loves to experiment with unusual vehicle drive systems and configurations to find out how they perform under the dynamic conditions of real-world use. Internal combustion engines and driveshafts don’t tend to fit in those vehicles, so Bruton often utilizes electric motors. He usually turns…

New display technology features magnetic pixels
Reading Time: 2 minutesArduino Team — August 24th, 2022 Display technology, from cathode-ray tubes to LCD screens, exists to convey information to humans visually and it does that very well. But the lack of physical presence makes visual displays useless for almost everything else. The blind can’t feel pixels and computers need resource-intensive algorithms to…

Building an electronic pantograph with Hall effect sensors
Reading Time: 2 minutesArduino Team — August 22nd, 2022 A pantograph is a machine that lets an artist copy an image by tracing the original. Traditional mechanical pantographs use a complex linkage system to move the output pen relative to the stylus. While 1:1 pantographs do serve a purpose, the real value comes from a…

Star Wars-themed device monitors indoor environmental conditions
Reading Time: 2 minutesArduino Team — August 22nd, 2022 We don’t need to tell you that Star Wars is a wildly popular franchise. If you include all of the movies, video games, novels, theme park attractions, and so on, it is the fifth-highest-grossing media franchise of all time (somehow just behind Winnie the Pooh). Because of its popularity, Star…

Transforming a 3D printer into a four-axis camera slider
Reading Time: 2 minutesArduino Team — August 19th, 2022 When creating videos, making smooth, level movements at a constant speed is often a very important requirement, as sudden changes can leave viewers uncomfortable. But rather than purchasing an expensive gimbal-stabilized rig or a commercial motorized camera platform, Instructables user dslrdiy decided to devise their own four-axis system using…

Back to the Future remote shows real DeLorean speed
Reading Time: 2 minutesArduino Team — August 18th, 2022 In the Back to the Future films, the iconic DeLorean time machine had to reach 88mph in order to jump forward or backward in time. Even in 1985, it wasn’t very hard for a family sedan to reach 88mph, but that’s not the point. To show viewers the…

Make your own motorcycle monitor for the race track with a Nano 33 IoT
Reading Time: 2 minutesArduino Team — August 17th, 2022 If you’ve ever had the pleasure of riding a motorcycle on a track, then you know that it quickly becomes competitive — even if the competition is yourself. You want to cut your lap times, increase your lean angle, brake later after a straight, and accelerate…

Building the worst digital camera ever
Reading Time: 2 minutesArduino Team — August 16th, 2022 Digital cameras work by letting light through a lens onto a sensor composed of photosites, each with a photodiode that outputs a signal relative to the brightness of the light. Modern digital camera sensors have millions of photosites, each of which contains a microscopic photodiode. The…

Real Robot One is a high-performance robotic arm that you can build yourself
Reading Time: 2 minutesArduino Team — August 15th, 2022 Robotic arms are versatile machines and are great for learning about principles of robotics or even doing useful work for hobbyists. That work might be picking and placing components on PCBs, packing boxes, or anything else you can imagine. But to perform that work well, the…

Reading analog gauges with the Nicla Vision
Reading Time: 2 minutesArduino Team — August 13th, 2022 Analog instruments are everywhere and used to measure pressure, temperature, power levels, and much more. Due to the advent of digital sensors, many of these became quickly obsolete, leaving the remaining ones to require either conversions to a digital format or frequent human monitoring. However, the…

This snake robot is large enough to ride upon
Reading Time: 2 minutesArduino Team — August 13th, 2022 If a robot is rideable, is it still a robot or is it a vehicle? We would argue that if it rolls on standard automobile-style wheels or even tank tracks, it is a vehicle. But James Bruton’s eight-wheeled robot snake bike is quite clearly something else.…

A wearable, waterproof, wireless human-machine interface
Reading Time: 2 minutesArduino Team — August 10th, 2022 “Human-machine interface” (HMI) is a general term that describes any physical input or output hardware that people can use to interface with systems (like computers) and vice versa. That very broad definition usually applies to computer input devices like keyboards or output devices like monitors. The…

Affordable CAT scan machine built with an Arduino
Reading Time: 2 minutesArduino Team — August 9th, 2022 A CT (computed tomography), or CAT (computed axial tomography), scan is a type of medical imaging technique in which multiple X-ray “slices” come together to form a pseudo-3D model. CT scanners are the kinds of medical equipment that are so expensive that manufacturers don’t even bother…

Building a DIY laser modem
Reading Time: 2 minutesArduino Team — August 8th, 2022 All digital communication ultimately comes down to transmitting ones and zeroes, but there are many ways to achieve that. One can encode that binary data as modulation in a radio signal or simply pulse electricity through a wire. But one of the most interesting methods is…

This high-precision AC meter handles inductive loads
Reading Time: 2 minutesArduino Team — August 5th, 2022 AC (alternating current) meters are useful tools for measuring power draw. One might use an AC meter to monitor the power consumption of their devices and appliances with the goal of lowering their energy bill. Makers in particular can benefit from AC meters to learn about…

Over-engineered robotic scalp scratcher knows all the moves
Reading Time: 2 minutesArduino Team — August 5th, 2022 Those cheap wire-arm head massagers are great at giving your scalp a nice, relaxing rub. But they’re handheld implements that force the user to either manipulate the massager themselves or talk a partner into performing the task. David McDaid decided that the experience would be much…

LEGO-firing turret targets tender tootsies
Reading Time: 2 minutesArduino Team — August 4th, 2022 Stepping on LEGO bricks is a meme for a reason: it really @#$%&! hurts. LEGO brick design is ingenious, but the engineers did not consider the ramifications of their minimalist construction system. We’ve seen people do crazy things for Internet points, such as walk across a…
