Controlling a bionic hand with tinyML keyword spotting

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 from five SG90 servo motors, with each one moving […]

Monitoring the force of a 20-ton hydraulic press

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, and torsional strength. The easiest way to test compressive […]

Classic Macintosh gets a massive ePaper display

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 largely have the Macintosh to thank for modern GUIs. […]

An Arduino controls this strange two-wheel steering e-bike

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 to Arduino to control the motors and read the […]

New display technology features magnetic pixels

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 make sense of the images we feed them. That’s […]

Building an electronic pantograph with Hall effect sensors

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 pantograph’s ability to scale the output. It is possible […]

Star Wars-themed device monitors indoor environmental conditions

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 Wars themes find their way into every facet of life. […]

Transforming a 3D printer into a four-axis camera slider

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 member dslrdiy decided to devise their own four-axis system using a repurposed 3D printer with the goal of being […]

Back to the Future remote shows real DeLorean speed

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 car’s current speed and increase tension, the prop designers […]

Make your own motorcycle monitor for the race track with a Nano 33 IoT

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 harder as you come out of a turn. But […]
