Electronic instrument tuners have existed now for several decades, but the ones with a great amount of precision can cost over a thousand dollars to the consumer, which is far above what many are willing or able to pay. To address this issue of high prices while still maintaining a high degree of accuracy, Jan […]
Near-field communication, or NFC for short, has started popping up everywhere as a way to easily pay, unlock doors, or even start a car. And now it can do one more thing: locate and track objects within a room. Researchers at Carnegie Mellon University’s Laboratory for Emerging Wireless Technologies have come up with an ingenious method to […]
Nearly everyone alive today has never the technical marvel that is the mechanical television. In short, the work by quickly strobing a light through a disc that has holes cut around its perimeter, with each hole being slightly lower than its predecessor. Combined with the persistence of vision effect, this gives the illusion of a […]
Stream Decks have gained a great deal of popularity within recent years. However, increased demand and a limited supply of them has caused their prices to skyrocket and availability to dwindle, leading many to seek alternatives. The streamer known as CoCoaCoCi has created a DIY Stream Deck before, but this first iteration only had a 3.5” touchscreen […]
Many modern automobile manufacturers have switched from traditional analog gauges to digital LCD screens. These let the driver configure their dashboard to suit their needs. When driving on the highway, they might want to see a map and a speedometer. When on the track, they can switch that to a tachometer, g-force meter, and shift […]
Although an Arduino can be a great way to provide computing power for a mobile robot, you’ll need a variety of other electronics and mechanical components to get it going. In his write-up, computer science student Niels Post outlines how he constructed a robotic platform that travels via two stepper motors, along with casters to keep […]
Electric trimmers allow you to shed unwanted hair, with the side effect of a constant buzzing sound. This noise is related to the motor’s speed, which as shown in Device Orchestra’s video below, doesn’t necessarily have to be continuous. It could instead be tuned to play music. After removing the stock circuit board on a […]
Slide whistles and recorders can be great for learning music, and perhaps a bit of fun, but what about teaching a robot to play such a wind instrument? The Mixed Signal’s MIDI-controlled system could be used for just that. The project is comprised of a 3D-printed fipple and piston that go into a PVC tube, while […]
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 […]
Researchers from the University of Auckland in New Zealand’s Augmented Human Lab are exploring a new way to construct interactive touch surfaces using finger-mounted audio transducers. VersaTouch — which works on everyday surfaces — uses one or more receivers to measure sound waves emanating from the wearer’s “augmented” fingers, allowing it to calculate their positions […]
