 All right, this week INMPI is from Pocket. Pocket. Pocket. You say pocket. They make the pocket. No, it's a pocket meter, because, well, I guess you could poke things with it, but it's fits in your pocket. Yeah. So I saw this on digikey.com. When I always love cute, adorable things, I'm a sucker for things that fit into your pocket. So they make a multimeter. They did, I think, a crowdfunding campaign, but now they're, I think, the second or third generation of product. This is the pocket meter, and it's like a key chain, shaped-sized multimeter, and it's got, you know, their thing that I think is adorable is the leads come out. Like, you know, we used to have like ethernet cords or whatever, or like little foam cords that would come on one of these spools, and you could pull the cables out. So it does that, and so what's nice is you don't have that kind of wound-up bundle of cables. It actually does kind of like all slip into the body of this little, you know, large key chain-sized thing. Actually, let's go to the overhead now, because I'll show that. I will say, by the way, I took this apart because I wanted to see what chip was used in it. So this doesn't work quite as well anymore, the thing, but believe me, it normally works quite well. It's just like the spring. I kind of, like, a little metal piece came out. Most of you are not going to take these apart, like we do. Yeah, I took it apart. So there's a coin battery here, CR-2030, which is replaceable. What chip is it? It's the EFM, it's a Silabs EFM32BF3, I think. It's a Bluetooth 32-bit cortex from Silabs. But these are the little probes, and so you can even, you know, you grab them and you can probe things. It also does come with some nice grabby micrograbbers. So this would see this, I think, plugs into here quite nicely. And so now you can have a micrograbber. But this is optional. It comes in a case also if you like. But let's see if this works. Well, I remember when you showed this to me before. I was like, oh, is there like a screen? And you said there's an app. So this is basically like a little, it's almost like an AirTag, an Apple AirTag, but it's a multimeter. Yeah, and if you don't break the spring when you press the button, it zips back quite nicely. So I worked a little bit. But anyways, I'll show it down in a moment. Anyway, so let's go back to the computer. This is what it looks like. So now you see you pulled the leads out and it's battery powered. And it doesn't have a screen because you're supposed to use your phone. So you download for your phone or your tablet. There's Android or iOS apps. And it actually paired very nicely. You don't have to do anything special. You just, it just kind of is advertising and you can pair to it. Give you little tips and hints on how to use it. And then you go straight into the modes. And so I note that because it's portrait mode, the top and bottom, it's two different screenshots. So at the top, you can see there's a multimeter, oscilloscope, and logger mode. And then at the bottom is the oscilloscope mode where you type it to acquire data. So the multimeter mode, I will say is instantaneous. The oscilloscope mode is not, and I'll show that in a little bit. Two things is that you're like, well, okay, so there's a non rechargeable coin cell battery. Well, how do you know when the battery is about to die? It'll actually warn you, it'll say battery low when you open up the app, if the battery is getting low. How long is it less than a battery? I don't know, you know, probably a couple of dozen hours. There's no on-off switch that I can note. I think it actually, you know, auto-offs, I guess, when it doesn't get data from the app on your phone or tablet. I didn't notice either way, you know, like any way to turn it off, I just quit the app and it seemed to not work. And then when I open the app again, it worked again. So it's magical. That said, the Silabs EFM series is pretty low power. Second, there is a multiple mode you can see on the side or, you know, resistance and continuity and voltage and all that good stuff. And you might be also wondering, well, like, you know, current mode is kind of weird. It does come with a fuse. There's a warning when you go to current mode. So, you know, you have to kind of double, you have to click and then click another thing because with current mode, it's very easy to blow the internal fuse. There's a two amp fuse inside. So I like that I gave you a warning. I like that they tell you when the battery is low. Next step, okay, multimeter like plain mode. So this is kind of what it's most useful for. It can do temperature, resistance, AC current, DC current. I think the limit is I think 60 volts DC and then for AC, I think it's like 40 volts or so. There's diode check. There's continuity and the beep comes from your phone, of course, there's no speaker in the device. You know, for doing basic voltage measurements, it's instantaneous, right? Which is really nice for continuity check or resistance checking. You get instantaneous feedback. So it's really good for that purpose. So maybe I'll try to do a live demo. So the thing that I'm always interested in is, okay, it says it's an oscilloscope. So is it an oscilloscope? Yes, technically it is. I will warn that it is not a live streaming oscilloscope, right? So it's more kind of like a data logger that can like trigger and then send chunks of data to your phone. So what you have to do is you have to press that red thing and it will sample data for you and then transmit it all back and then you can look at it and kind of zoom in and out. It doesn't do what you would normally, you know, what normal people think of as an oscilloscope where it's kind of like continuous trigger mode. You know, I still think it's very useful. I just want people to know that, you know, you can do analog, you can do, you know, digital, and this is me sampling an audio signal. It's perfectly useful, but it is not instant trigger, rolling trigger. It's data capture. So maybe I'll go quickly to the overhead. Yeah, let's do that. We'll show where it's at on the Digikey site. Okay, let's try this live demo. The... It's a little risky. The Ion and PI segment is purchased by Digikey and Adafruit. Okay. So... Is it in focus? Nope. I might want to... Okay, so it says, you know, connect to the device and it blinks blue. And then you go into this mode. So for example, continuity mode, that's an easy one to test. So you can remove the leads and then again, it doesn't normally do that, but I broke it. And then... Hold on, let me make this loud. Oh wait, sorry, that's diode. So very annoying. But let's say I want to do temperature. So temperature reading and then let's do voltage. And then I will... I think it's handy just to keep in your toolbox or your bag if you have a phone. Yeah. Because you never know when you're going to need one. It is a true pocket meter, you know, which is unique. So let's measure this battery. It was into here. Can I get my proves into there? So this battery is 3.66 volts. So that's kind of nice. I can measure. Another nice thing is because it's battery powered, you know, it's a floating voltage. So this is three volts, you know, measuring the voltage on this LCD. So all that stuff is pretty good. And then if you go to the oscilloscope mode, you know, if you capture data, you know, I'm not going to see anything because I don't have it connected. Maybe I can go together and then I'll get ground data. So yeah, you acquire data and then it displays it. Actually, let me... Maybe you can tap the... Can you tap the red button? Red button? Yeah, yeah, yeah. Yeah, it's hard to do two things at once. All right, try now. That's weird. Oh, you know what? I think I have to... Oh, there you go. All right, hold on. Let's try now. Yeah, so you can see there's some signal here that I'm getting. So, I don't know what it is exactly, but it's like some power supply signal. So, you know, you're not going to get constant streaming data. I think eventually it would be nice if that was something that was added. I know it's tough to do, but maybe with BLE5 and maybe if it's like pre-triggering and there's enough RAM on the device. I think that that's the only thing that didn't make it like, oh my God, this is the most amazing ever. But it's still very useful and it does fit in your pocket. It does fit in your purse and it does fit on your key chain. So, for that $100, it's a pretty good deal and it's in stock and Digi-Key. Available in stock. You can get it on Digi-Key. There's a short URL on the screen. Yeah, look, I'm definitely going to keep this for sure. Oh, yeah, and then there is the part number that you can search. And we have a little bit of a short video from them and we're going to play it and we'll get to new products right after this. Okay. Electronics are an integral part of our everyday lives.
