Often I hear this question: “how can I get better solder joints?” Without looking at anything they are doing, I already know that they could be using more flux. Or, as I point out …

A powerful, but an underused feature of digital oscilloscopes is the trigger circuit. Learn from James how to use an oscilloscope’s trigger to find glitches, measure pulse widths, …

When running on a battery, it is important to know what parts of your circuit draw the most current. Profiling is a process where you look at sections of code or interactions with …

When connecting multiple oscilloscope probes to a circuit, does each probe need to connect to ground? The short answer is yes! Why? The long answer is kind because of the ground …

Every digital oscilloscope I have ever used has a menu or dialog for “acquisition modes.” And depending on the current settings, changing that acquisition mode does not seem to …

Bench power supplies are an essential piece of test equipment gear. And like most test gear, they have a wide range of capabilities. For example, the B&K Precision 9140 is a triple …

fix broken polygons in kicad In KiCad 6, using the Polygon tool makes square boards easy. Just select the Edge.Cuts layer, then the polygon tool, and draw a square. However, if you …

Using a Metcal GT120, we look at three ways to improve your soldering skills. Using flux, setting a correct temperature, and selecting the proper tip all result in better solder …

Measuring a switch-mode power supply (SMPS) with a DMM might show a stable voltage. But the same DC rail on an oscilloscope can show a completely different story! In this video, …

When you cannot get an oscilloscope probe into a tight spot, can you just use a piece of wire? Sometimes. When signal integrity matters, you CAN use a low-cost DIY solder-in probe. …
