This Halloween my son Max, came up with the idea to drop a spider on anyone who tries to ring our doorbell… I immediately jumped on the idea and we started to work on it. Using a simple ultrasonic distance sensor (HC-SR04) and a servo connected to an arduino we made this project in about […]

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, has released an innovative full-color ambient light sensor (ALS) that helps smartphones take better pictures and present more visually accurate data on screen displays. By simultaneously providing scene color temperature, ultra-violet (UVA) radiation level, and lighting frequency information, the VD6281 lets the camera correct white balance and
Makers, developers and electronic enthusiasts looking for a way to add a digital smell detector, sensor and nose to their project may be interested in a new piece of hardware called the Smell Inspector, designed by SmartNanotubes Technologies based in Germany. The Smell Inspector takes the form of a developers kit and ready to use electronic
This is a radar, designed to detect the distance and direction an object is from the ultrasonic sensor. With the ultrasonic sensor connected to a servo, it has the ability to rotate 180 degress, similar to a radar utilised to detect the position of planes. As the radar wasn’t my original idea, I have also
A team of researchers from Germany and Argentina have devised an ultra-thin planar Hall effect (PHE) sensor capable of detecting very faint magnetic fields even when flexed or wrapped around a wire. by Julien Happich @ www.eenewsembedded.com In a paper titled “Highly compliant planar Hall effect sensor with sub 200 nT sensitivity” published in Nature’s npj
Researchers develop thin sensor to detect magnetic fields down to 200nT Continue Reading
YouTuber DuctTape Mechanic has published a new tutorial on how you can create your very own Arduino powered speed bag to count your punches as you work out. Using a recessed NPN capacitive sensor to pick up when the bag hits the back of the platform, the sensor sends “hit” signals to a small Arduino

View this project on my website to see a circuit simulation and a video! Acoustic levitation is made possible through the fact that sound behaves as a wave. When two sound waves intersect each other, they can either constructively or destructively interfere with each other. (This is how noise-cancelling headphones work) This project uses an ultrasonic distance
A research team from UC Berkeley Univercity (Daniel S. Drew, Nathan O. Lambert, Craig B. Schindler, and Kristofer S. J. Pister) has designed and build mini microbot that is capable of taking flight without any motor or moving part. This is all achieved using electrohydrodynamic thrust to provide lift, which is a technique to create air-flow

With the increase of high integration programmable chips, FPGAs are getting more and more popular. FPGAs has been traditionally known to be generally complex, but a new line of FPGAs have been showing some promise and that is believed that will help increase their popularity. Tiny FPGAs are the next promising thing, they are low-cost

Know someone that constantly struggle to get out of bed, comes late to work and you are just want to give them a nudge in the morning. Now you can make your own Hey Pillow. Inside the pillow is embedded with an annoying piezo buzzer that you can control via your phone, so that you
