If this was a classroom, he would have been interrupted about a dozen times or more for students to ask questions. There are a lot of questions that could have been asked and answered.</p>

However, IT's beyond swamped at the moment (understatement of the century), so unless somebody needs a break from their backbreaking projects, it might take a while for anything to happen.</p>

For all N00bs watching and wondering what a transient is:<br>
A transient in layman's terms is a signal irregularity. We tend to think of AC as a perfect sine, and DC as a perfect flat signal but in reality it takes some time (very small) to get there. The signal irregularities happening until you get the "regular shape" of the signal is what a transient is. :)<br>
Some info :<br>
ESR = Equivalent Series Resistance<br>
quiescent = stable<br>

your workshop music station sounds interesting, and I might have some useful input. You could attach the frequency visualizer to an LED cube. I've made a tutorial on how to do so on my projects blog, Mushroo.me. This LED cube is controlled by a custom shield I developed. The videos on there right now aren't great because the resistors are too high (I forgot about the PWM effect due to use of Persistence of vision) and I'm not about to order $1.50 worth of resisters and pay $8 for shipping!</p>

Nothing like an object lesson to drive the point home. And to demonstrate that caps store energy, charge up a couple big ones and toss them to coworkers.</p>

Conflicting sounds (especially in the frequency of the human voice--like that danged organ in the soundtrack) make it hard for those of us who spent our formative years working in recording studios in Hollywood during the golden age of rock to focus on what the lecturer is saying.<br>
Please, please, please; cut the music.</p>

It would be nice if it was left off for something technical like this.</p>

I liked finally understanding why I had to solder in two different capacitors that looked pretty much the same :)<br>
I think it would be interesting to go over the reasons why some other SparkFun kits are assembled the way they are, especially for ones where it might not be completely obvious.</p>

Liked the video though. I also think that if you are going to be using this project to talk about different aspects of electronics, the videos should be every coupe weeks instead of every month so it won't take too long in between videos.</p>

I've been working in the world of electricity for quite some time now and even though these first 2 videos have been on the very basics I've managed to learn something each time! It's amazing what looking at things from another point of view can do.<br>

Also, while I realise I'm not on the same level as most people here at sparkfun it seemed like this episode was like a merge of very basic principles and quite high level principles.
