Hello, and welcome to Al's electronic classroom. This is Al and you guys should know my little black lab Best Buy Now, best is a little bit tired here, but she told me she wanted to say hello to everybody. So say hello best. Best is saying hello. All right, hey, we finally got awesome lab one up and take a look at it. I just wanted to give you a little bit of an introduction or a heads up what's going on the best heads up of what's going on here.

And in this lab, what I call awesome electronic lab one we're going to talk about measuring Well first of all, we're going to start off with multimeter basics. I'm going to give you an overview of the basics. multimeter my best is looking at me a basic overview of my my of electronic multimedia. And the next thing we're going to do is talk about the specs and some of the some of the ways we can measure things with it. Some of the ranges, some of the functionality of the button, and then we're going to focus in on measuring voltage with this both DC voltage, DC current, and then we're going to do some resistance measurements on this, and a few other things and that that'll wrap up awesome lab one, and I've done most of the lectures right now. I think there's probably, oh, I don't have it in front of me, but I think there's going to be around three, three and a half hours of, of total videos.

What I've done is I've given you A lot what I call a lecture lab where I explain things and then I've given you what I call follow along labs and these follow along labs offer you, you play the video. And then you you go in and you get the equipment, and then you follow along and, and do the same things I do and maybe experiment a little bit get familiar with the equipment. That's, that's what these labs or that part of the lectures is is designed to do. Now, what I've done following this is I've given you a resource list. Alright, it's actually a PDF on this on this section here. So download this this PDF, it's called lab resources, and click the links you'll go to Amazon.

I've given you a couple of different meters. I've given you some resistors a resistor kit. Some of the clip leads Use and I use some nine volt batteries here and I've given you a link to that. So you can buy these off of Amazon. Okay, I have an affiliate account there. And I mean, if you're going to buy them off Amazon, please click my affiliate link, that'll give me a little bit more revenue and I can continue doing this.

And I really again, I really enjoy doing this. All right, it's, it's not going to cut if you buy it off Amazon, it's not going to cost you anymore. Alright. And if you don't want to buy it on Amazon, you, I'll give you an idea of what to buy. You can go to your local electronics store. You can find some other places on the web if you so desire.

But again, if you're going to buy it on Amazon, I really would appreciate it if you clicked on my link and get it that way. So to do that, all you need to do was download this PDF, open it up in the piece A viewer and you'll see the links and we're gonna we're going to go through this anyways. All right, I really think you're gonna like this. Okay, and then after we do this what I call awesome lab one, we're going to be doing awesome lab two, which will be picking up AC voltage. And we're going to talk a little bit more about meter basics multimeter basics and that type of thing. And then on the on the last portion here, we're going to design a small power supply.

And the next group of courses that I put up, we're actually going to start building things and one of the things that I think we're going to do first is a transistor amplifier with some additive best transistor amplifier and then after that, finally going to do it guys. We're going to build a vacuum tube amplifier. So with that said, this is Al and my favorite little dog bass, who happens to be a rescue dog people and you know that I advocate For rescue dogs, so we're going to say we'll see in the courses, take care and happy learning. Bye Bye now. Okay, here's the PDF that I was talking about. And what I suggest is pull a PDF down, put it in your view or you'll get the links.

And I just want to go over a couple of things real quick. Here are the meters that I spoke about. And the first one is the one I actually use in the presentation. And okay, if I go to the first one here, this is the one I use in the presentation. As you can see, this is the one that I that I actually use in the presentation. It's a great meter.

We're here at Amazon. So there you go. If you want to buy it you Put it in your cart. And we're good. So let's stop and look at the other meter that I've given you. The next one is set to CITY AUTO ranging digital multimeter.

And let's go to Amazon. This one I looked at it, it's a good it's a good meter arm. It's got pretty good reviews here. And it's it's 1599 compared to the 62. It doesn't have as many of the scales as the purse meter does, meaning it doesn't have a temperature scale. It doesn't have a frequency scale.

It's just a basic multimeter but quite honestly, it looks like it it's it's good. I looked at it. It can measure both AC and DC Current, right. And as you can see that right there, all right, where, if you look, you'll see I see a little sine wave and straight line. That's telling me that that can measure both AC and DC current. Some of the other less expensive ones wouldn't measure AC current.

So I kind of skipped over them. But I think for the money, this is a, this is a good meter. So here's one more for you. Okay, the next one that I selected was again was an E to city, auto ranging t RMS 6000. And if you'll notice, it has both a temperature has both a temperature and frequency range and it's very, very similar to the one that I use the 8260. c and give it a shot. I mean, the price on this one is a little less I think this one is Yeah, this one's 2999.

The first one was, the one that I use is 62. Right now, I think the one that I have is a little bit more rugged but but quite honestly, if you're in a, a, a lab, a home lab atmosphere, it you know, be careful, you're not going to take a beating with that and this for 2999 it should suffice. So here's another one that I recommend. Okay, I also put a link to the clip leads that I use. And I mean there's a there's a ton of different clip leads I picked. These are very similar to the ones that I have They're very similar to the ones that I have, um, they've got alligator clips, you can buy smaller clip leads if you want.

For me, this suffices very nicely and they're only $10 and 99 cents. If you're going to use it, maybe if he use real, real fine a real small components, these may be a little bit big but for what we do here, I think they're fine. As we get into a little bit more circuitry, I may use a different style of clip lead. We'll show you that when we get there but for what we're doing right now and for general clip leads to be on the electronic bench. This is fine. Okay.

And then like I said, 50 of them for 1099. Good deal. All right, the next step, the next resource or that is the resistor kit right there. I think this is a good deal. Let me let me explain. Let me explain a little bit more on that.

Now these are a little bit different than the ones that I, I've used in the demonstration and let me explain why I changed that. The ones that I use in the demonstration aquata watt, these, these are half watt resistors. So that means they are a little bit bigger. And they're, they're rough. I believe they're 5%. I looked at it, they're 5%.

So they've got three bands for their rough three bands to tell you what their posted ohmic value is. And then the fourth band has a tolerance span. So they're five plus or minus 5%. And again, the reason I selected a half watt not the quarter watt like I'm using in the lab is it's easier to see the colors. All right. And for a new student who's trying to Get used to the color code it's going to be a little bit easier okay you're not squinting or really looking at you know really looking at it again get a magnifying glass to see what the color is.

It'd be a little bit easier to interpret than a quarter watch so that's that's why we selected the half squat and I think the difference between price was was like $1 maybe $1 50. So these are good um, you've got a lot of different values here. Let me scroll down here I think we they give you the values Yeah, his. Let me open this up a little bit. I in my practice description that the different values so we go as low as like one or up to one megohm and in between, and these are all standard values. This thread and 60 pieces half watt resistor kit.

Get the give you a reason as to color code guide and this this compartment. So for I think it's $8 and 99 cents. This is really a really a good deal. So there you go. And you'll you'll be using these, we're going to we're not going to be using all 365 pieces in the lab but as we go along and especially if you stay in the business, you're going to need a resistor value. You just, you know, you go get it and that's it.

So Alright, so Enough said here and let's go on. Okay, the next one here is the potential ometer. And notice I've got optional you can I mean I'm gonna I'm gonna demonstrate this in the follow along lab. All right, so there's 20 pieces here. They're, they're assorted from Five K to 500 K. Again, I'm going to show you if you so desire to buy these or, or maybe if you have electronic store close by, you can go down and buy one. But basically, for $12 and 99 cents right here, you get 20 pieces in their assortment.

And, you know, as we get to build more things, like I talked about building a transistor amplifier, we may, we may need a volume control, and we would use one of these at this point, I'm not sure what value we would use. It depends upon the design of the circuitry, but we would use we could use a potentiometer as as part of the volume control circuitry. So enough said and again, this one's optional. They're all optional, actually. But this one may be a little bit more optional than other I mean, you don't have to go out buy these you can watch the follow along lab. You know, that's your call.

And there you go. So one more and when we're done with the resource page. All right, the next one is the nine volt battery, we use three of them. Ah, we use three of them as I stated there's a pack of four. I just picked these I'm not sure if these batteries are any better than the ones that I've used, but they're nine volt. They're a standard nine volt battery and, and then again, feel free to get a battery, any place that you want, but since I put everything up on Amazon, I put the battery so there's nothing special about these batteries.

They're alkaline so they may last a little bit longer for you. That's pretty much it. So we've we've gone through the resource page and That's it. So we'll see you in the lectures and have a good day and this is Al saying take care
