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 [...]

What is 3D MLC NAND Flash Memory?

To unleash performance fit for the next generation of computers, Transcend has released its MTE850 M.2 Solid State Device (SSD), based on 3D MLC NAND flash memory. The device utilizes the PCI Express Gen3 x4 interface and supports the latest NVMe standard. According to Transcend, this SSD targets high-end applications such as gaming, digital audio and video production, and multiple uses in the enterprise. Typically, such applications demand constant processing of heavy workloads, while not willing Read more [...]

What are Synchronous Condensers?

All manufacturing and industrial plants around the world face the unique problem of lagging power factor. Ideally, the voltage and current vectors should align perfectly for any AC power system feeding a load. In actual practice, however, the current either leads or lags the voltage by a few degrees, depending on whether the load is capacitive or inductive. Power factor is the cosine of the angle the current vector makes with the voltage vector as the reference. A positive power factor less than Read more [...]

Using Relays to Detect Faults

Different types of relays are in use in every-day life. These include relays constructed from electromechanical elements such as from solenoids, induction discs, hinged armatures, or from solid-state elements such as from transistors, magnetic or operational amplifiers, silicon-controlled-rectifiers (SCRs), diodes, or digital computers using microprocessors and analog-to-digital converters. Development of protection with relays began with the electromagnetic types, and most descriptions of relay Read more [...]

Which are Better – Round Cables or Flat Cables?

Both types of cables are available in the market—round ones and flats, and people use them according to the requirements of the application. As round cables were the first to arrive on the market, the industry has been using them as standard for long, in applications ranging from renewable energy to automation and manufacturing in general. Flat cables arrived late on the scene, and offer a niche solution presently. However, they are gaining ground steadily for applications within the civil-aircraft Read more [...]

Raspberry Pi to Linux Desktop

You may have bought a new Single Board Computer (SBC), and by any chance, it is the ubiquitous Raspberry Pi (RBPi). You have probably had scores of projects lined up to try on the new RBPi, and you have enjoyed countless hours of fun and excitement on your SBC. After having exhausted all the listed projects, you are searching for newer projects to try on. Instead of allowing the RBPi to remain idle in a corner, why not turn it into a Linux desktop? At least, until another overwhelming project turns Read more [...]

Battery Monitoring with Comparators

So many portable consumer electronics gadgets in use today use small, button- or coin-cell batteries. Sometimes it is necessary to monitor their state-of-charge (SOC) and health efficiently without affecting their SOC significantly, but this can be a challenge. However, simple low-power monitoring circuits for small batteries using comparators can overcome this challenge. Managing Batteries in Portable Systems Usually, the system engineer budgets the system power requirements carefully during the Read more [...]

What are Miniature Slide Guides?

Slide guides are industrial mechanical guides to reduce friction in linear motions. They use rolling elements, either hardened steel rollers or balls, moving along two raceways, with a stick-slip arrangement. This provides a smooth linear motion in either direction even when the load is heavy. Usually, slide guides carry their loads on one or more blocks or carriages riding on a rail. Instead of carrying loads, they can also guide other components, making sure they move smoothly and easily along Read more [...]

Measuring Very High Currents

High currents, such as 500 Amps and above, are common nowadays. Industries regularly use equipment consuming high currents, and vehicle batteries experience very high currents for a short time during starting. With vehicles increasingly trending towards their electric versions, it is becoming necessary to be able to measure high currents with precision. Increasingly, it is increasingly becoming critical to monitor current consumed accurately for ensuring performance and long-term reliability. Current Read more [...]

Let the Raspberry Pi Monitor Energy

If you are looking for monitoring energy remotely, an open source system that uses the ever-popular single board computer, the Raspberry Pi (RBPi) may be suitable. The company, OpenEnergyMonitor, makes the open-source tools for monitoring energy, and at present, they are using the RBPi3. According to their co-founder Glyn Hudson, the aim of OpenEnergyMonitor is to help people understand and relate to how they use energy from their energy systems, and the challenges of sustainable energy. The system Read more [...]
