Making fire detection more accurate with ML sensor fusion
Reading Time: 2 minutesThe mere presence of a flame in a controlled environment, such as a candle, is perfectly acceptable, but when tasked with determining if there is cause for alarm solely using vision data, embedded AI models can struggle with false positives. Solomon Githu’s project aims to lower the rate of incorrect detections with a multi-input…

A gamified approach to therapy and motor skills testing
Reading Time: 2 minutesFor children who experience certain developmental delays, specific types of physical therapies are often employed to assist them in improving their balance and motor skills/coordination. Ivan Hernandez, Juan Diego Zambrano, and Abdelrahman Farag were looking for a way to quantify the progress patients make while simultaneously presenting a gamified approach, so they developed…

Improving comfort and energy efficiency in buildings with automated windows and blinds
Reading Time: 2 minutesWhen dealing with indoor climate controls, there are several variables to consider, such as the outside weather, people’s tolerance to hot or cold temperatures, and the desired level of energy savings. Windows can make this extra challenging, as they let in large amounts of light/heat and can create poorly insulated regions, which…

Nothin’ but (neural) net: Track your basketball score with a Nano 33 BLE Sense
Reading Time: 2 minutesWhen playing a short game of basketball, few people enjoy having to consciously track their number of successful throws. Yet when it comes to automation, nearly all systems rely on infrared or visual proximity detection as a way to determine when a shot has gone through the basket versus missed. This is…

This recycling bin sorts waste using audio classification
Reading Time: 2 minutesAlthough a large percentage of our trash can be recycled, only a small percentage actually makes it to the proper facility due, in part, to being improperly sorted. So as an effort to help keep more of our trash out of landfills without the need for extra work, Samuel Alexander built a smart recycling…

This stretchable wearable sensor provides accurate knee tracking
Reading Time: 2 minutesHealth tracking is a vital component to recovering after an injury or simply trying to improve one’s own fitness, and although accelerometer-based devices are decent at tracking general activity, they fail to accurately monitor specific areas of the body such as joint movement. This is why a team of researchers from the…

This machine uses cornstarch to fashion biodegradable pottery
Reading Time: 2 minutesThe art of making pottery has existed for tens of thousands of years, and the materials used have stayed relatively similar as nearly all items were made from clay which was left to harden either from the sun or via a kiln. But for those who wish to do only a little…

Recreating a century-old Argentinian rainmaking machine
Reading Time: 2 minutesYou’ve heard about the many different snake oil concoctions shilled by con men over the centuries, but did you know that inventors created a variety of machines for similar purposes? The most well-known example is probably the belt vibrator, which purported to induce weight loss. In Argentina during the 1930s, Juan Baigorri…

Monitoring hospital bed occupancy with an Arduino Nano 33 BLE Sense
Reading Time: 2 minutesIn care facilities and hospitals, being able to tell when beds are occupied or free is vital knowledge for the staff, as they can move onto other tasks more quickly with up-to-date information. Adam Milton-Barker’s hospital bed occupancy detection system aims to accomplish this goal by combining embedded machine learning models and connected hardware…

Using sensor fusion and tinyML to detect fires
Reading Time: 2 minutesThe damage and destruction caused by structure fires to both people and the property itself is immense, which is why accurate and reliable fire detection systems are a must-have. As Nekhil R. notes in his write-up, the current rule-based algorithms and simple sensor configurations can lead to reduced accuracy, thus showing a…
