When you think of a “7-segment” display, your mind naturally goes to something involving LCD or LED technology. As seen here, however, this 0-9 pattern can also be duplicated mechanically using a series of electromagnets. Neeraj Rane’s 3D-printed device is controlled by an Arduino Nano, along with a shift register. These activate seven hand-wound coils that […]
Inspired by an old FlipFold TV ad, YouTuber Ty Palowski decided to make his own automated shirt folding machine. Palowski’s device is made in four folding sections, which lie flat to accept the unfolded piece of laundry. When the shirt is properly placed, a capacitive touch sensor starts the process, which is controlled via an […]
Troy Hawkins (AKA “tomatoskins”) had come across an interesting wooden perpetual calendar, which used a trio of rings to show the month, day, and day of the week. The only problem is that it’s manually operated, subject to human error or neglect. So when he decided to construct his own version, he added an Arduino to […]
Whether you work in meters, feet, inches, or kilometers — or any number of other units corresponding to properties that you need to convey — conversions are a fact of life when making things. While this could mean pulling up a Google tab or flipping open a Machinery’s Handbook and doing a few hand calculations, […]
For a class project, University of Stuttgart students Ekin Sila Sahin, Lior Skoury, and Simon Treml came up with a unique painting robot named the Physical Twin. The Physical Twin travels on a three-wheeled chassis and mounts a four-axis arm with a brush. An operator controls the arm to dip the brush into an onboard paint container, […]
As you work on a project, lighting needs change dynamically. This can mean manual adjustment after manual adjustment, making do with generalized lighting, or having a helper hold a flashlight. Harry Gao, however, has a different solution in the form of a novel robotic task lamp. Gao’s 3D-printed device uses a USB camera to take images […]
Cable-mounted cameras can be a lot of fun for capturing moving footage. Although commercial cable cam options can be expensive, this system by Kasper Mortensen of MAKESOME is comprised of 3D-printed components with a receiver and wheel salvaged from an RC car. The build was meant to use some of the toy vehicle’s other components, however […]
Car spoilers can provide downforce for better performance, or simply give the appearance of speed. To take things to another level, Michael Rechtin designed his own custom wing that doesn’t just sit there, but pitches up and down via a pair of servos. The system utilizes an Arduino Nano along with an MPU-6050 for control, […]
Hand movements have long been used as a computer interface method, but as reported here, the MemGlove from a team of MIT CSAIL researchers takes things several steps further. This augmented glove can sense hand poses and how it’s applying pressure to an object. The wearable uses a novel arrangement of 16 electrodes to detect hand position […]
Seven-segment displays are normally diminutive items, able to show info from a clock or other device, in a size that’s easily tucked away when not needed. Jegatheesan Soundarapandian’s single-digit display, however, is just the opposite standing at nearly seven feet tall. The project is constructed out of cardboard, with a PVC spine for extra strength. Inside, […]
