The Rexing V1 is a simple wedge-shaped dash camera that films in a 1080-line progressive scanning format. The lens is made of six glass layers and is fish-eyed to capture a 170° view of whatever it sees. There’s also a built-in vibration sensor, called a G-sensor in the promotional literature, that automatically locks any files recorded during a moment of unusual … [Read More...]

What’s new with Wi-Fi 6? Focus on high-efficiency
The first wide-spread home electrical appliance was the toaster, and 90% of homes today still have one.[i] Today, wireless connectivity to the internet is as ubiquitous as the electricity was a hundred years ago. Smartphones, tablets, wearables, laptops, televisions, Nest thermostats, Alexa, Google Home, Ring video doorbell sensors, surveillance cameras door locks, smart lighting, and […]
Motor field-oriented control, Part 1: Principles
Field-oriented control, also known as vector control, is a calculation-intensive algorithm for motor control which is now practical due to advances in ICs; it offers improved efficiency along with superior control of torque and other performance parameters. Motor control—and doing so accurately and efficiently—is a topic of great interest. Field-oriented control (FOC), sometimes called vector […]
How to learn anything for free: Massive open online courses
Positions for someone with a Masters degree in Data Science are $300K and up, according to a friend of a friend of mine who works in Human Resources for a well-known company.

Choosing PCB materials to optimize applications, Part II
Have you ever wondered which type of Printed Circuit Board (PCB) materials would be worth investing in to improve signal integrity? Would your high-frequency signaling work better with a tighter, more uniform weave in the core sheet of the PCB? What’s a high-frequency signal, anyway? When should you invest in a rigid, moisture-proof PCB? Properties […]
Choosing PCB materials to optimize applications, Part I
There are many different materials and methods for creating PCB materials. The electronics used in numerous applications benefits from the large number of options for PCBs. Hobbyists often choose the least expensive PCB, however, it’s essential to choose appropriate PCB materials when prototyping is done, and high-volume product development and manufacturing become the focus. Applications […]
Programmable Logic Controllers, Part 1: Basics and background
The programmable logic control (PLC) is the controller for many industrial processes; it is tightly focused and optimized for the task due to its rugged electrical, software, mechanical, and thermal design.

Exploring the difference between a digital oscilloscope and a spectrum analyzer
Traditionally, only the spectrum analyzer was capable of displaying electrical and electromagnetic signals in the frequency domain and the oscilloscope took control of the time domain. More recently, each instrument has become competent in the other’s territory. But this overlapping tendency is far from absolute. Oscilloscopes, working in the Math>FFT mode, have always had a […]
