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 [...]

What is E-Smog and How to Detect it?

Many people claim advancement in technology and the proliferation of electronic devices is creating a sea of electromagnetic waves around us, and this eSmog is actually a cause for many of the illnesses we are afflicted with nowadays. While eSmog causing bad health is up for debate, some people seem to be more sensitive to it than others are. However, the presence of electromagnetic waves around us cannot be ruled out, with greater concentrations around devices such as computers, mobile phones, Wi-Fi Read more [...]

Accurate Power Monitoring with LTC2992

Linear Technology Corporation, now a part of Analog Devices, Inc., has recently placed on the market a power monitoring IC, LTC2992, which offers a wide-range, dual monitoring system for current, voltage, and power for 0-100 VDC rails. The IC is self-contained and does not need additional circuitry for functioning. Users get a variety of options for operating the LTC2992. For instance, they can derive power from a 3-100 VDC monitored supply, or from a 2.7-100 VDC secondary supply, or from the shunt Read more [...]

It is Time for Chip Speakers

So far, speakers have been electromechanical devices, with a coil moving within a magnetic core, attached to a baffle or driver to move the air for producing the sound. With devices going down in size, manufacturers have been facing difficulties in producing electromechanical speakers in smaller sizes. Piezoelectric speakers are available, but they operate on a very narrow bandwidth. Now USound GmBH, from Graz, Austria, has presented an audio speaker based on micro-electro-mechanical-system (MEMS) Read more [...]

Oscilloscopes Lose their Faces

The word oscilloscope usually conjures up images of a box with a display. Earlier, oscilloscopes were bulky devices with a display made of a cathode ray tube, but later the models became sleeker, and came with a liquid crystal display. Another difference was in their method of measurement. Whereas there were analog units earlier, later models sported an analog to digital converter inside, which converted all analog signals to digital data. Nevertheless, the display continued to be a part of the oscilloscope. However, Read more [...]
