Conventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a battery, boost converter, […]
The whole purpose of machine automation is to eliminate human needs and errors. A CNC machine doesn’t get tired, doesn’t need breaks, and performs a task exactly the same way every time. But what if that weren’t true? What if machines experienced human emotions and let it affect their work like we do? That’s the […]
In order to build wearables that react to motion, most people tend to reach for accelerometers, gyroscopes, and flex sensors. But due to their higher cost, teacher Gord Payne wanted to create a low-cost alternative that could be easily sourced and integrated into projects — like that of his student who had designed a hand sculpture and […]
For people not familiar with American Sign Language (ASL), being able to recognize what certain hand motions and positions mean is a nearly impossible task. To make this process easier, Hackster.io user ayooluwa98 came up with the idea to integrate various motion, resistive, and touch sensors into a single glove that could convert these signals into understandable text and […]
If you look at footage from the search and rescue efforts following any disaster, you’ll see that first responders have a very difficult time navigating through rubble to find people in need of emergency care. They also have to take extra precautions, as gas line ruptures and other hazards present dangers they don’t normally face. […]
Drivers who are experiencing tiredness become large dangers to both themselves and anyone else around them on the road, as reaction times, concentration, and alertness are all greatly impaired. This is why Shebin Jose Jacob decided to create a drowsiness detection system that can accurately tell when someone behind the wheel is fatigued and should pull over […]
After finishing his recent Binbot 9000, James Bruton noticed a serious problem: the robot can’t climb stairs. That is an issue when his home does, in fact, contain stairs. Bruton has plans to build a beverage delivery robot and didn’t want to make the same mistake again. So to test the concept, he developed this […]
If you’re looking for an ever faster, smoother, and more rewarding way to build your own IoT projects at home, the new MKR IoT Carrier Rev2 could be perfect for you. The new carrier can work with any board from the MKR family, giving you a wide choice of connectivity options to match the needs […]
Art is inherently subjective and its meaning varies from one person to the next. But many pieces have widespread appeal as they tap into some emotion we all share. Interactive art pieces tend to stimulate our senses of curiosity and wonder. Niklas Roy’s “Visitors Magnet” installation harnesses the mystique of magnetism to provide that wonder. […]
Ensuring adequate and restful sleep is vital for maintaining good health, as decreases in sleep quality have been proven to cause a whole host of problems. University of Toronto researchers Zongyan Yao and Xilin Liu recognized this vital aspect to well-being and wanted to build an inexpensive device that could classify the various stages of sleep as […]
