An open-source, breath-controlled MIDI device
Reading Time: 2 minutesThe simplest MIDI (Musical Instrument Digital Interface) input devices use good ol’ fashioned buttons: push a button and the device sends a MIDI message to trigger a specific note. But that control scheme doesn’t replicate the flexibility of a real instrument very well, because a standard button is a binary mechanism. To…

This robotic beer tray keeps servers from spilling suds
Reading Time: 2 minutesExperienced servers are masters of balance and coordination, being able to carry several full glasses on a tray without spilling a drop. But many of us lack that skill and can’t carry even a single glass across a room without splashing half of it on our feet. To help the clumsy among…

Shape-changing user interface improves haptic navigation
Reading Time: 2 minutesAlmost all haptic feedback today comes in the form of vibration. But vibratory haptic feedback is clearly lacking, as it cannot convey information with any kind of precision or granularity. The user notices the vibration and very course patterns may be recognizable, but that is a rudimentary approach that requires a lot…

TactorBots is a complete toolkit for robotic touch
Reading Time: 2 minutesSo much of the research and development in the area of haptic feedback focuses on universal devices that can create a wide range of tactile sensations. But that has proven to be a massive challenge, as it is very difficult to package the number of actuators necessary for that flexibility in a…

Fingertip force control aids in sports and musical training
Reading Time: 2 minutesA great number of activities require the precise application of force with the fingertips. When playing a guitar, for example, you must exert the proper amount of force to push a string against the fret board. Training is difficult, because new guitarists don’t know how much force to apply. This wearable system…

Emoband strokes and squeezes your wrist
Reading Time: 2 minutesModern consumer devices are fantastic at providing visual and auditory stimulation, but they fail to excite any of the other senses. At most, we get some tactile sensation in the form of haptic feedback. But those course vibrations do little more than provide an indication that something is happening, which is why…

Training embedded audio classifiers for the Nicla Voice on synthetic datasets
Reading Time: 2 minutesThe task of gathering enough data to classify distinct sounds not captured in a larger, more robust dataset can be very time-consuming, at least until now. In his write-up, Shakhizat Nurgaliyev describes how he used an array of AI tools to automatically create a keyword spotting dataset without the need for speaking into a microphone. The…

Convert an old hour meter to track your job time
Reading Time: 2 minutesHour meters are common for many types of machinery, because they serve a similar to purpose as your car’s odometer. When time running is a more important metric than distance, an hour meter is a good choice. And because they’re common, it is easy to find hour meters in any style you…

Stewart platforms actuate Doc Ock tentacle
Reading Time: 2 minutesOctopus tentacles are, essentially, long continuous muscles — a bit like your tongue. That anatomy gives octopuses incredible dexterity, but it is very difficult to replicate in robots. Artificial “muscle” fiber isn’t very practical yet, which is why roboticists turn to more conventional means of actuation. Cable-driven tentacles are popular, but they…
