Tracking Micro-Fluidic Flows

Scientists have taken analytical chemistry to such advancements that it can detect the effects of extremely tiny amounts of liquids—triggering the requirement of a need to measure such microflow of liquids. NIST, the National Institute of Standards and Technology, has produced such a microflow measurement device, the size of a nickel, and has filed a provisional patent application for it. The device is capable of measuring movements of nanoliters (nL) of liquid per minute. A nanoliter is a billionth Read more [...]

The Latest in Li-Fi

Newly developed technologies are allowing wireless networks to operate several hundred times faster than Wi-Fi—one of them is Li-Fi or Light Fidelity. Simply by switching on a light bulb, it is possible to encode data within the visible light spectrum rather than allow them to ride on radio waves as traditional wireless technologies such as Wi-Fi do. So far, research labs had confined Li-Fi within their closed doors. Of late, however, several new products using the Li-Fi technology has started Read more [...]

Mimicking Nerves with Memristors

Researchers are planning to build a computer mimicking the monumental computational power of the human brain. For this, they prefer to use memristors, because these devices vary their electrical resistance on the basis of the memory of their past activity. Memristors are semiconductor devices, and at NIST, the National Institute of Standards and Technology, researchers demonstrate the long and mysterious manner of the inner workings of memristors, explaining their ability to behave as the short-term Read more [...]

Industrial Controls and the Raspberry Pi

Industries with control equipment prefer to use a standardized system of mounting components such as circuit breakers within equipment racks. The most popular arrangement is the DIN rail and enclosure. The rails are typically made from a cold-rolled carbon steel sheet and zinc-plated or chromated for a bright surface finish. DIN is the acronym for Deutsches Institut fur Normung in Germany, and the rest of the world has adopted their standards as the EN and IEC standards. The famous single board Read more [...]

What are Digital Circuit Breakers?

We need protection from fires resulting from an electrical overload caused by a faulty device or an accidental short circuit. The huge current from the overload heats up wires and their insulation may go up in flames. There are several ways to activate this protection. The oldest method consists of a fuse wire. Usually, this is a thin wire enclosed in a casing. The material of the fuse wire is carefully chosen to heat up and melt (blow) when a certain current level is exceeded. Melting of the wire Read more [...]

Meca500 – The Tiny Six-Axis Robot

Although there are plenty of robots available in the market for a myriad jobs, one of the most compact, and accurate robot is the Meca500. Launched by the Quebec based Mecademic from Montreal, the manufacturers claim it is the smallest, and most precise six-axis industrialist robot arm in the market. According to Mecademic, users can fit Meca500 easily within an already existing equipment and consider it as an automation component, much simpler than most other industrial robots are. According to Read more [...]

BrailleBox with the Raspberry Pi

Reading, whether online or from the page of a book is a simple affair for those endowed with the power of sight. However, for those who are sightless, or have lost their eyesight, totally or partially, reading can be cumbersome, if not impossible. The Braille system, by allowing a changeover to the sense of touch, helps sight-impaired people to read. Braille uses a system of raised dots that blind or those with low vision can follow with their fingertips. It is not a separate language, but rather Read more [...]

What is Open Bionics?

There are people all around the world that may loose limbs for various reasons -- wars, illness, and accidents being the three major ones. Artificial limbs do alleviate a part of the loss these folks experience, but often, their high cost means not all can afford a prosthetic limb. Open Bionics is a company making affordable bionic arms, making kids feel like superheroes. A start-up tech company in the UK, Open-Bionics is changing the way people see prostheses. The 3-D printed prostheses Open Bionics Read more [...]

Less Expensive 3D Printing

3-D printing is no longer a new technology. Several design studios use it, along with some home users who make their products using 3-D printers. However, the general opinion is it is expensive, slow, and unable to compete with traditional mass-manufacturing processes. Although considered a revolutionary technology, so far, 3-D printing has remained on the periphery. Now, a Massachusetts company is trying to prove the general opinion wrong. Desktop Metal is coming out with a 3-D metal printing system Read more [...]

Bluetooth 5.0

Custodians of the Bluetooth standard are a flexible lot, considering the enhancements the popular short-range 2.4 GHz wireless technology has been receiving. The Bluetooth SIG or Special Interest Group has allowed it to evolve in ways not envisioned by the inventors. Their foresight will be allowing this technology to expand beyond three billion shipments beginning next year. The latest incarnation of the technology is the Bluetooth 5.0. This indicates the seriousness with which SIG wants to entrench Read more [...]
