Using a Thermal Camera for PCB Inspection and 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

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 Make Advanced BLDC Motor Controllers
In this project article, we’re going to be taking a different approach to my typical project. Driving a brushless motor is relatively simple from a schematic perspective; however, there is a large amount of theory about brushless direct current motors that you need to understand to be successful. If you only have experience with brushed motors or no experience with driving motors at all, we will be covering everything you need to know. You can

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
