How my Tech Graveyard Made My Life Fun
Let’s face it- the tech graveyard is something that haunts you. It’s a drawer full of phones and tablets that all work, but haven’t been charged for months or even years. I decided to challenge myself and find uses for my graveyard. I had such a blast making them all work and I’ve learned quite a bit from it. So here’s the plan. Each device will have to have a very specific use. The only big fear I had was that a device was so old that no app would even support it.
Data transfer system connects silicon chips
Researchers have developed a data transfer system that pairs high-frequency silicon chips with a polymer cable as thin a strand of hair. Courtesy: Massachusetts Institute of Technology (MIT) Researchers have developed a data transfer system that can transmit information 10 times faster than a USB. The new link pairs high-frequency silicon chips with a polymer cable as thin a strand of hair.
Three signs it might be time to upgrade a PLC
While there might be a temptation to keep older programmable logic controllers (PLCs) running a long time, having to replace them is not a desirable situation. While some components can be found and purchased online, if the primary source for replacement parts is a site like eBay or a site that specializes in second-hand parts, it’s likely time to upgrade.
Digitalization as a competitive advantage in control panel construction
Today, engineering, design and documentation account for nearly half of the costs in control panel construction. While the mechanical design and automation of machines are largely software-driven, many electrical engineering tasks, are still performed manually. For example, selecting components and calculating cable cross-sections and short-circuit currents. These tasks are time consuming and frequently lead to errors. As a result, there is high potential for optimization.
Five questions every CISO should ask about OT cybersecurity
Companies have been protecting information technology (IT) systems for years, but do they really need to worry about operational technology (OT) security? The answer is a definite yes. Chief information security officers (CISOs) should consider these five questions when getting started. 1. Who should be involved in the OT security program? This is the first question for a reason. In many information technology (IT) organizations, the answer is clear.
Expanding edge control
Learning Objectives Modern PLCs can act as practical Internet of Things (IoT) platforms, while still performing as an edge controller. Many edge devices use message queuing telemetry transport (MQTT) to transmit data. Edge control is best fulfilled by using PLCs that can support IoT initiatives right out of the box. For as long as operators have interacted with machinery and equipment, the concepts of the industrial “edge” and “edge control” have existed.
AIoT benefits for manufacturers
The Artificial Intelligence of Things (AIoT) refers to the adoption of AI capabilities in Internet of Things (IoT) applications. In simple terms, while the Internet of Things (IoT) is reactive while Artificial Intelligence of Things (AIoT) is proactive. The AIoT relates to the combination of AI and the IoT with the goal of achieving greater efficiency in complex operations – it looks to improve human and machine interactions and to enhance data driven decision making.
Control system connectivity update
Digitalization requires communication hubs, a role well-suited to PLCs and HMIs. Many industrial plants and facilities are executing asset digitalization projects by incorporating Industrial Internet of Things (IIoT) elements and implementing other Industry 4.0 initiatives. A key enabler for these efforts is connectivity between field devices, such as sensors and instruments, and higher-level computing platforms. Connectivity usually is via company intranets and the Internet.

Applying Apps in Industrial Automation
In our daily activities, we prefer to use an app instead of browser-based access. For example, it’s possible to connect to a search site, type in the word “Maps,” and open up the corresponding web-based application to find directions. Instead, most people have a navigation app installed on their phone, and they simply click on it to find their way.
Outcomes of beta blocker use in cocaine-associated chest pain: a meta-analysis
Objectives Beta blockers (β-blockers) remain a standard therapy in the early treatment of acute coronary syndromes. However, β-blocker therapy in patients with cocaine-associated chest pain (CACP) continues to be an area of debate due to the potential risk of unopposed α-adrenergic stimulation and coronary vasospasm. Therefore, we performed a systematic review and meta-analysis of available studies to compare outcomes of β-blocker versus no β-blocker use among patients with CACP.
Controller selection criteria
Basic choices and selection criteria follow to help in specifying a controller for an industrial application. Eleven criteria in the table can help when selecting a controller type from among relays, timers, analog instruments, smart relays, programmable logic controller (PLCs), and programmable automation controllers (PACs).

Stepper Motors Step Up for Machine Automation
Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used because of their simple implementation, attractive price/performance ratio, and high torque at low speeds.
Review: Superior Spider-man
2K The long-anticipated return of the one true Peter Parker has finally occurred! Following the 32 issues of Superior Spider-man, today marks the release of The Amazing Spider-man #1 (comic, not movie)!

Doctor Strange Movie will be Matrix/Miyazaki/Ditko/Kubrick Mash up
1.9K Try saying that title five times fast! Marvel’s President of Production, Kevin Feige recently explained to Badass Digest how Marvel plans on introducing magic into the Marvel realm. Feige was reported to describe the Dr. Strange Movie to be “a Ditko/Kubrick/Miyazaki/The Matrix mind-trip.” Strong words for a movie starring a superhero that the average non-dork has never heard of. But lets look at all aspects of this movie and really guess at how this movie will turn out.

Super Team for Superman! Geoff Johns and John Romita Jr. Confirmed as New Writer and Artist
2.7K It’s a bird! It’s a plane! No, look–it’s Geoff Johns and John Romita Jr.! Anyone that knows me can tell you I’m not the biggest Superman fan, but when you have the legendary Geoff Johns (top left) as a writer and the masterful John Romita Jr. (top right) as the artist then you can tell me they’re writing My Little Pony and I would still be absolutely ecstatic (no offense to you fans out there). Many of you are probably wondering who these guys are and why I’m geeking out about them.
