Vacuum fluorescent displays (VFDs) have a distinct cool blue-greenish glow, and were once used in a wide range of devices, from VCRs to microwave ovens and even car dashboards. Although extremely popular way back when, they can be more difficult to source today. In the video below, Scotty Allen of the Strange Parts YouTube channel […]
Sure, we’ve seen low-cost DIY 3D printers with wooden frames before, but not a 3D printer that actually ‘prints’ wood. That’s exactly what Shane Wighton and his Formlabs hackathon team have done. (Although probably more along the lines of a hybrid additive/subtractive CNC machine that makes parts out of 3/4″ particleboard.) The device first cuts […]
Michael Koopman wanted to learn piano. However, after finding this pursuit frustrating, he instead decided to assemble his own 3D-printed MIDI jammer keyboard, inspired by the AXiS-49 interface pad. His instrument is controlled via an Arduino Due, with 85 buttons arranged in a diagonal pattern. This allows for whole steps on the horizontal axis, fourths […]
Ultrasound images are an important tool for medical diagnosis, and while units used by doctors can be very expensive, getting a basic image doesn’t have to be. Inspired by this attempt at a $500 ultrasound machine seen here, maker “stoppi71” decided to create his own using a 5 MHz ultrasound transducer via a paint-thickness gauge. […]
While you’ve been hearing about virtual reality for the last 20 years or so, today the hardware required to build such a rig is finally to the point where it’s within the reach of consumers. As seen here, Relativty is a SteamVR-compatible headset that can be made for around $100. Relativty uses a 3D-printed frame […]
When conversing face-to-face, there are a wide range of other emotions and inflections conveyed by our facial and body expressions. But what if you can’t express emotion this way, whether due to a physical impairment, or simply because of a covering—like a dust mask—temporarily hides your beautiful smile, and perhaps your hands are otherwise occupied? […]
While there are tools that allow the visually impaired to interact with computers, conveying spacial relationships, such as those needed for gaming, is certainly a challenge. To address this, researchers have come up with DualPanto. As the name implies, the system uses two pantographs for location IO, and on the end of each is a […]
Smartwatches can keep us informed of incoming information at a glance, but responding still takes the use of another hand, potentially occupied by other tasks. Researchers at Dartmouth College are trying to change that with their new WrisText system. The device divides the outside of a Ticwatch 2 into six sections of letters, selected by […]
As part of his master’s studies at Eindhoven University, Felix Ros created a haptic interface that uses a five-bar linkage system to not only take input from one’s finger, but also act as a feedback device via a pair of rotary outputs. Designed for autonomous cars, “Scribble” lets a driver draw their way through traffic. They decide […]
When the Power Glove was released in the early 1990s, the idea that you could control games with hand motions was incredible, but like the Virtual Boy that followed years later, the hardware of the day just couldn’t keep up. Today, hardware has finally gotten to the point where this type of interface could be […]
