Current on Bald Engineer

No-Contact Current Measurements | Workbench Wednesday #24

One of the safest ways to measure current is with a clamp. Clamps do not require you to break the circuit and they safely measure wires with thousands of amps. In this video, we measure DC current in the lab, AC current of a reflow oven controller, and the DC current in a car using a Tenma 72-7226 True RMS Clamp Meter. This video was the last one I did before moving to a new house / lab.

6 Simple Mistakes Electronics Beginners Make

Mon, 30 Jun 2014 14:00:47 +0000

Sometimes the hardest lessons are the ones you have to learn multiple times. When getting started with Electronics circuits, there’s a handful of things that can ruin a day (or experiment.) Here are 6 mistakes I made when I got started, and mistakes I see in the beginner classes I teach. In fairness #6 isn’t one I did starting out, because Fritzing wasn’t around. However, it took me a while to learn the value of providing a schematic, even a simple sketched out block diagram.

A new series on AddOhms, Electronics basics, starting with: Voltage, Current, and Power Explained.

Starting with this new AddOhms TutorialCast series, we are taking a look at Electronics Basics. The first topic is on the differences between Voltage, Current, and Power. The twist on this explanation is that we are not using the usual “electricity is like water” analogy engineers seem to love. Instead, we just use plain language to explain the difference between these concepts. From a production point of view, I am really having fun with these videos. Using some green card stock, imagination, and easy to use tools, I am able to achieve some pretty cool effects. Well, I think they are pretty cool. Check out this screen shot from Final Cut Pro X.
