Creating High Pin Count Schematic Symbols Quickly
Making schematic symbols is quick and painless when you use regular expressions and leverage Altium Designer’s expansive toolkit.
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
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
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
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
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.
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
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
How to Design a Boost Voltage Regulator

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. For the next switching power supply project from my
From RC to Atomic Clocks: All Clock Sources
In almost modern circuits, especially whenever digital circuitry is involved, you will find some kind of clock source. All clock sources present a series of tradeoffs regarding stability, reliability, size, power consumption and cost. Luckily for us, such tradeoffs are relatively simple and can be explained almost fully within this single article. We’ll discuss the pros and cons of each clock source, from the RC in a 555-powered oscillator, to a
Temperature Sensor Project: Analog Temperature Sensor ICs
Learn more about the fourth class of temperature sensors in a series of articles that are all about measuring temperature. Discover their advantages and disadvantages as well as common topologies for their implementation.

Customizing Performance-Based Electrical Design Rules in Altium Designer
Electrical design rules go beyond manufacturing and assembly. PCBs also require electrical design rules that are based on a signals’ electrical behavior.
How to Use Thermocouples in Your Next Project
Thermocouples are the final sensor type in a series where we look at all the main types of temperature sensors you might use in an electronics project. In this series, we have looked at the various ways to implement different temperature sensors in your project. At the end of the series, we’ll be putting the sensors and implementations in a head to head competition using real-world conditions. Through this real-world testing, will gain a better

Eli Hughes shows us how on-demand manufacturing through a PCB manufacturer's cloud platform helped him quickly produce a set of high-quality prototypes for a MCU board.
Pandemic PCB Prototyping: Building Electronics From Your Living Room
It feels like everyone is writing an article these days about how they’re managing (or not managing) with stay-at-home orders due to COVID-19 restrictions. At the time of writing, California (where I am based) has the highest number of cases over any other state in the United States. To combat the pandemic, most non-essential businesses have been closed or open in a limited fashion. This means that folks who are able to work from home (e.g
