Happy 3rd Birthday

3 Years ago... It's hard to believe, but only three years ago I posted the first AddOhms Video. The series had a strange start. I tried four different times until I figured out the "whiteboard" style that AddOhms is famous for today. It's funny because when I go back to the first four episodes, they are hard for me to watch, but continue to be popular. Regardless, I so appreciate the support of Fans and look forward to where we'll be three years from now!

Here's the latest one, which was on linear regulators. A bit of a change!

Linear Regulators | AO #17

The LM7805 is a very popular voltage regulator. Curious about how it works? In this AddOhms Tutorial, we look at what is a Linear Voltage Regulator and how to use them in your circuits. 

AddOhms Forums

New since the last tutorial are the AddOhms Forums. I'm giving thought to closing comments on YouTube. Not because of the comment quality but because it is very difficult to answer questions well through YouTube's comment structure. Here's the show notes and forum for Episode #17 - Linear Regulators

Ep #14: NI's VirtualBench

National Instruments (NI), is probably best known for the LabVIEW software and modular instruments. The past few years, they have introduced more innovative test and measurement products than any other T&M manufacturer, at least, in our opinion.

Their latest box is called the "VirtualBench." It's a lab's worth of equipment in a single box at a reasonable price.

In this AddOhms video, we take a look the high-level capabilities of the VirtualBench. We even see what happens when a 555 timer isn't blinking an LED.
