Monitoring Sound & Vibration for Process Control

In a production environment, one can always find two common themes for the successful application of acoustical or vibrational monitoring. Usually, workers judge the noise or vibration event as being the start or end of a particular process. Initiated by such an event, an automated control system can easily minimize any loss of production. On the production floor, control of manufacturing processes have used continuous monitoring of sound and vibration for the past several years. For instance Brüel Read more [...]

Nanoparticles Toggle a Window between Clear and Reflective

By applying a coating on a clear window, it has been possible to convert the window into a one-way reflective mirror. If applied correctly, the coating allows people from inside the room to see outside, but for those outside the room, the windowpanes act like mirrors, preventing them from looking in. To revert to the clear glass, it is necessary to peel off the coating. Clearly, this is not a reversible process. A research team from the Imperial College London has now developed a process by which Read more [...]

The CHIP Computer Rivals the Raspberry Pi

Since the 2010s, there has been a new wave of single board computers smaller than the credit card able to perform like any major computer. Offering a range of tinkering and educational adventures, two of the most popular SBCs, the Raspberry Pi and the CHIP computer, are two unique products. While the Raspberry Pi or RBPi was the product of a UK nonprofit supporting children’s education, the Chip started as a successful Kickstarter project that raised more than two million dollars. The RBPi family Read more [...]

Window Blinds Offer Shade and Electricity

Everyone is looking for clean energy, because awareness is growing of the problems the use of fossil fuels is creating. Although alternate forms of energy from wind and waves is viable now, solar energy is more accessible to all, since it needs only a solar cell placed in the sun to start generating energy. SolarGaps from Ukraine offers a new type of window blinds that do double duty. You can control the smart shades by an app on your smartphone, and while they screen your house from the fierce rays Read more [...]

What is an i-Robot?

The level of CO2 in our atmosphere is increasing at alarming levels, affecting all life on Earth either directly or indirectly. For instance, it is related to global warming risks, reducing the quantity of ice in the polar regions, which in turn changes the level of seas all around as the ice melts. This has significant consequences on several human activities such as fishing. It also affects the submarine environment adversely, together with the associated biological sphere. For long, scientists Read more [...]

Where are AREE Rovers Going?

NASA is planning new types of rover explorers for observing extreme environments, such as the surface of Venus. They plan to build simple yet robust vehicles. AREE is their acronym for Automaton Rovers for Extreme Environments. NASA’s Curiosity Rover on Mars has been roving and exploring the planet’s surface for the last five years. Among rovers, Curiosity is at the top position. It uses special systems for rejecting heat, X-band receiver and transmitter for communicating directly with Earth, Read more [...]

Butterfly IQ – Smartphone Connected Ultrasound Scanner

Traditional ultrasound scanners are rather expensive, and rarely do people own one to use at home. However, that may be about to change, as Butterfly IQ has now obtained FDA clearance for a portable ultrasound scanner that anyone can use by connecting to their smartphones. Connecticut-based Butterfly IQ has made an innovative ultrasound scanner that uses a semiconductor chip for generating the ultrasonic signals, rather than the piezoelectric crystal transducers that traditional ultrasound machines Read more [...]

Progress in the World of Internet of Things

Although many in the electronics field lambast the Internet of Things (IoT) as an inappropriate or inadequate acronym, IoT is a space to huge to be confined to these narrow adjectives. In reality, IoT requires a blanket description, as it covers a vast arena. Problems arise from compartmentalization and although various spaces such as industrial and medical have established a big head start, others have yet to launch their true separate identities. For the electronics designer this means taking Read more [...]

Why Panic Buttons are Going Wireless

Panic buttons or emergency stop switches are extremely important for protecting workers, machinery, and products from catastrophic failures. Traditionally, manufacturers include them with their machinery, and most are hard-wired. However, things are changing and now, these red emergency switches are finally going wireless. When a machine malfunctions, or a critical incident occurs, operators often have to press these last resort switches to bring the system or the entire machine to a halt quickly Read more [...]

Beemo Works With Raspberry Pi

Even adults watching Adventure Time wish to own a personal BMO, the quirky living game system from the Be More episode of the show. Although based on the GameBoy, BMO is a digital friend calling out through the nostalgia lens of our childhood times. Now Bob Herzberg has created Beemo, a BMO for his daughter and her friends. In building the living little boy, Beemo, Herzberg used the popular single board computer Raspberry Pi (RBPi), which be runs on battery power, a USB battery pack. Although his Read more [...]
