Remotely Powering Devices, Wirelessly With electronic devices being available in smaller and smaller sizes and the prevalence of wi-fi networks, the rise of remote monitoring devices around the home and the workplace continues to grow. Smart heating solutions now place sensors in every room, monitoring everything from temperature to occupancy to provide a highly efficient zonal heating system. Intruder detection systems no longer require thousands of meters of wiring to be installed Read Article

Guidelines for Creating Useful Schematic Symbols The schematic symbols that you use to represent the components are at the heart of your schematic design. The quality of the symbol and how it is arranged can be one of the most critical factors influencing your schematic’s readability. A poor quality schematic symbol will lead to an unreadable schematic sheet that is difficult to understand. I created the largest open-source library for Altium Designer over five years ago, initially as a way to Read Article

Using a Thermal Camera for PCB Diagnostics There has likely been a time when you’ve powered on a freshly built prototype for the first time, only to find you’ve hit the current limit on the lab power supply. Even as you increase the current limit to way beyond what you would expect your board to draw, the lab power supply is still limited. If it’s safe, you poke around the board with your finger, but you can’t feel any parts that are hot to the touch. Also, probing around with a Read Article

What does AMD’s purchase of Xilinx mean for the electronics world? Who is Xilinx? While AMD is focused on microprocessor production, Xilinx is a specialist producer of FPGA (field-programmable gate arrays), which are particularly useful for telecommunications applications, and the development of 5G across the world has opened up significant growth in this sector. The expected number of new 5G cellular base stations required over the next five to ten years will be in the millions. Xilinx has been one of the front Read Article

Create a High Current Buck Voltage Controller Mark Harris continues a deep dive into high current buck converter design with off-the-shelf components. We include component choice and PCB layout plus all the calculations and guidelines. Read Article

Smart Micro Fan Controller If you’ve ever had to wear eye protection for an extended period of time, especially if you have prescription inserts in that eye protection, you’ve probably noticed fogging can be a major issue. Last year I designed and 3D printed a small fan unit that mounts a 25mm x 25mm x 10mm fan on each side of a military eye protection. It directs a small flow of air over the inside of the lenses and keeps them clear even during physical exertion on cool Read Article

Create a Buck-Boost Power Supply In this series of articles, we’re looking at the design and implementation of the main types of power regulators and converters you might use in an electronics project. I gave a graduate engineer who I mentor a series of requirements to demonstrate each of these types and have recorded the results here so you can work through the same exercises and hopefully come up with the same results. The next switching regulator is the last in our switching Read Article

Assembly: The Last Step In The PCB Product Development Process As pointed out in previous articles, design is the first step in the PCB product development process, so the board designer needs to understand how the downstream processes will impact his design processes/selections/decisions, and this understanding needs to encompass both technical and financial considerations. These deliberations are viewed and weighted as trade-offs. What might make sense from a technical standpoint may not always make sense Read Article

Addressing Differential Signaling In Flex Circuits As noted in many previous articles, due to high-speed and high data-rate designs, most modern products utilize differential signaling. If utilizing the right design protocols and design toolsets, handling differential signaling in standard, rigid PCBs is easily doable. But utilizing differential signaling in flex circuits creates another set of issues, questions, and design challenges. This article will address how differential signaling is Read Article
