Networked Storage with the Raspberry Pi

With memory going cheap, almost everyone has a plethora of high-capacity hard disks lying around. Networking them makes it super convenient for use, as you can access files from any computer, even if they are remote. However, this can be an expensive proposition, unless you are using a convenient single board computer such as the Raspberry Pi (RBPi). The RBPi can be used to create a very cheap NAS setup with a few hard drives connected to a network and accessible from anywhere. Apart from the Read more [...]

Python Libraries for Machine Learning

Machine learning helps with many practical applications, suitably augmented by deep learning and with extensions of the overall field of artificial intelligence. Many people, with the help of analytics and statistics, are busy navigating the vast universe of deep or machine learning, artificial intelligence, and big data. However, they do not really have to qualify as data scientists, as popular machine learning libraries in Python are available. Machine learning is promoting deep learning and Read more [...]

Super Efficient Diamond Batteries from Nuclear Waste

So far, we have been dumping our dangerous nuclear waste into oceans or deep inside the earth, hoping they will stay there. Now, there is a better way out. Scientists are now confident they can use nuclear waste as a source of energy to convert radioactive gas into diamonds of the artificial type, not as jewelry, but to be used as batteries. Scientists claim the diamonds can generate their own electrical current. As they are made of radioactive material with long half-life, the batteries could Read more [...]

Explosion and Damage Proof High Energy Density Batteries

We seem to spend a major part of our waking life charging batteries of our smartphones, laptops, watches, wearables, and more. Although most of our gadgets work at lightning speeds, one common frustrating weakness lingers on—the batteries. Of course, they have improved tremendously in the last fifty years, yet they have retained characteristics such as being toxic, expensive, bulky, finicky, and most maddeningly, short-lived. The quest for a super battery does not end with smartphones alone, rather Read more [...]

Raspberry Pi to Displace the Business PC

For a business establishment, maintaining PCs for each of their several hundred employees can be an expensive proposition. It is much simpler and cheaper to have a centralized workstation with several thin clients connecting to it. The ubiquitous single board computer, the Raspberry Pi (RBPi) is a suitable component for use as such a thin client. As the low cost of the Raspberry Pi makes it a very attractive proposition for use as a thin client computer, Citrix is offering an HDX Ready Pi to replace Read more [...]

Volumio for the Raspberry Pi

When you search for a networked stand-alone audio player with a touch screen, most likely chances are you will only find big consumer grade amplifiers. Those with network support may not have a touch screen or else may be very expensive. Most disappointing will be those having an issue with space and mobility. The best way out of this dilemma is to build one with the famous single board computer, the Raspberry Pi (RBPi). You must start with an application that works on the RBPi. You can already Read more [...]

QSCR: Using A Wireless Hotspot To Charge Your Phone

Using the smartphone is always a pleasant experience, until the charge runs out. The only option left is to plug the phone into a charging arrangement, usually a mains-operated power supply that connects to the phone by a USB cable. The main disadvantage of this method is it limits the freedom of mobility of the phone until it is charged up again. That leaves people to wonder as to how long before smartphones could be charged wirelessly same as everyone uses Wi-Fi to link to the Internet. Now, Read more [...]

RX300 – The Windows 10 Thin Client with the Raspberry Pi

The Raspberry Pi (RBPi) has no hard disk, is stateless, and can work as a desktop terminal, which makes it an ideal candidate for use as a thin client. It connects to the data center for all its applications, sensitive data, memory, and runs a Remote Desktop Protocol such as the Windows Terminal Services. That makes the RBPi a virtual desktop computing model, as it runs virtualization software, and accesses hard drives in the data center. Thin client computing has thin clients, software services, Read more [...]

Dual Function LEDs & Multifunctional Displays

At the University of Illinois at Urbana-Champaign, researchers have made dual-function nanorod LEDs that could double as multifunctional displays. The researchers are also working with Dow Electronic Materials in Marlborough, Massachusetts. The LEDs are made of tiny nanorods arrayed in a thin film. They could enable new interactive functions and multitasking devices. The researchers report their advances in the February issue of the journal Science. According to Moonsub Shim, Professor of materials Read more [...]

Different Types of Industrial Cables

To wire up different components within electronic gadgets, hook-up and lead wires may be adequate, but the electric industry needs a vast variety of industrial cables to remain connected. Chief among these are power cables to carry high voltages and currents, and cables necessary for industrial automation and process control. Cables may conform to multiple standards such as UL, CSA, and others. Cables often have to transmit power or signal in industrial environments that may harbor the harshest conditions Read more [...]
