You would probably recognize a thermal printer as the thing that spits out receipts at a cash register. They offer a two key advantages: they do not require ink cartridges and they are compact. But because they print by applying heat to special paper that darkens when hot, they have low resolution and fidelity. If […]
Many people (especially those with autism spectrum disorder) have difficulty communicating with others around them. That is always a challenge, but becomes particularly noticeable when one cannot convey their emotions through body language. If someone can’t show that they’re not in the mood to talk, that may lead to confusing interactions. To help people express […]
Spectrum analysis is a technique that allows someone to observe the amplitude of various frequency ranges within a signal. The most common use case is in the world of audio engineering, as it is useful for tuning audio output. It can, for example, show you that a particular audio signal has little amplitude in the […]
Senior care homes may get a bad rap in popular culture, but they serve a legitimate and important purpose. As people age, their requirements for care can exceed the capability of their families. When that becomes the case, professional care may be prudent. To help those professionals care for residents, Hayden designed this system that […]
One of the most popular machines in any arcade is the Cyclone game, where a ring of LEDs illuminates in sequence and the player must push a button at the exact moment that a specific LED lights up. Get it just right and you can win a whole pile of tickets to spend in the […]
While it is easier now than ever before, getting into robotics is still daunting. In the past, aspiring roboticists were limited by budget and inaccessible technology. But today the challenge is an overwhelming abundance of options. It is hard to know where to start, which is why Saul designed a set of easy-to-build and affordable […]
The challenge Optimizing manufacturing processes is a requirement in any industry today, with electricity consumption in particular representing a major concern due to increased costs and instability. Analyzing energy use has therefore become a widespread need – and one that can also lead to early identification of anomalies and predictive maintenance: two important activities to […]
For those who have to put up with a snoring partner or roommate, the scourge of listening to those droning sounds can be maddening and lead to a decrease in the quality of one’s sleep. So, as an attempt to remedy this situation, Flin van Asperen devised a machine out of readily accessible components that […]
The 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 introduce more range, […]
Experienced 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 us, YouTuber The […]
