 Where in the world is that part that I need the great search with digiki? All right, lady. Yeah, okay Let's do it. So okay, so the rest of the overhead so I can point out this little thing So we're looking for a little shocky diode and we need one That's very small and we need one that carries a lot of current And we need that because we want to allow people to use batteries with the QT PI by having their a diode on their power supply and so we don't get Power voltage collisions. So let's go to the computer and We'll start Looking at what we're trying to do So this is the trinket M zero and the trinket M zero has two power inputs It has a battery input V-bat and it has the USB input which they call bus like bus voltage And you see there's two shocky diodes here The part number isn't specified because it's going to be a generic shocky And then whichever one of these is higher goes into this regulator which can supply 500 milliamps and Then that'll give you your three volts. And so this is a Very simple or power selector inexpensive simple hot swap, you know, yeah, you can get more complicated But for simplicity and cost not a lot beats this When we went to design the QT PI As I mentioned we turn off Some unused layers here to clean this up We have a five volt pin Ground pin and three volt. We don't have a battery input pin instead What's kind of interesting is you see this bus voltage? This is the five volt coming from USB it goes through this shocky diode and Into this five volt pin, which is a five volt output But you could also use this pin as an input if you connect a shocky diode Pointing into it from another power supply. So for people who are like, I really want to use what's funny because the pins are green It came out as a green screen. That's funny. Did green screen get somehow activated on this? Well, there's a green screen on me Now it's just funny. I got the schematic. This is green and it blacked out. It's kind of cool Yeah, I don't like that. Yeah, I'll try to fix this. I don't know why I don't care. I think it's funny. Yeah, sometimes it does this I don't know why Did I'm gonna try to fix this. Okay Okay, there you go. Yeah, okay great wonders of This is like when the weatherman disappears The weather person disappears on TV and everything like it's funny like the person wears like a green. Yeah. Yeah Okay, I fix it anyways So we do have one shocky diode because this one's required to make sure that We don't back feed into USB and then if you put another diode into this from an external power supply You can then have that diode oring. It's just that we only Put one diode one shocky down the PCB. Now this PCB is very small. It's not to use 0402 Components, this is an 0402 Resistor, I mean they're they're not that small and believe me they can get smaller and get 0201s and then like they're ridiculously 01005s But they are small. I didn't have space for my standard shocky diode Which is Here This is my standard shocky diode which is an MBR Oh five four one twenty zero whatever and this is SOD one twenty three So we need something smaller. So what's smaller? So I Looked up SOD diode sizes and actually saw this pretty cool image Which is very handy Okay, so this image Shows you the different sizes because capacitors and resistors have very nice sizing and 603 is 6mm by 3mm. 0402 is 4mm by 2mm. There's also metric sizes, but for the most part it's like 1206 is going to be Like bigger than 0805 and you know by how much like basically twice as big because each side is 50% larger, right? So The numbering for Diodes is like the opposite which always confuses me because the 123 is Larger than the 323 which is larger than the 523 which is larger than the 723 which is larger than the 923 so like Yeah, it's like not it's like the bigger the number the smaller it is Once in a while I do use SMA or SMB diodes, but these are like massive these are for huge voltages or like huge current dissipations but you know the SOD 123 size is pretty much what I've used for all my shocky diodes. I kind of like it and 323 or 523 is what I usually use for my Like 1 and 4148 or Z or diodes so smaller non high current carrying diodes But that doesn't mean we can't find one that's that small So let's go to Digikey and I will Start over So one exciting thing is as I was doing this Digikey updated their website. So the interface is a little bit different, but it's Similar enough. I believe the engineers at Digikey are updating their website Sunday they know we're doing desk of Lady Aida and they're like watching right now and they're like Let's see if she notices. We've secretly replaced Lady Aida's folders With the Digikey site. Yeah And this is why I'm actually very happy that I always do the search before our show because I would have gotten a little confused So you want to search for shocky diode? And the toughest part is spelling it. Don't put an E You want to put an E? You don't you want two T's and a CH. It's a guy It's a guy who's named shocky. Okay, so As usual you want to go to diode rectifier single single. We want like one individual diode and I'm going to pick my Standard things so this was for manufacturing. It's not like a one-off sample or anything So I definitely want to be active and I want tape and real I just want like a huge already able to buy like a whole wheel of them And that'll cut out all the like little components now Here's something that I noticed which is new So when you select cut tape to do your tape or real this stays You still get all those three options. They're now kind of like combined in one So don't be weirded out by that. I was a little weirded out, but it's okay. Okay next up I definitely only want surface mount because I don't have to pick and place it and The average current now the regulator for the Qt pie is a 500 milliamp regulator But USB can pretty much provide like one amp. I know like people are gonna tell me they're like, hey You know like the specification where USB is 500 milliamps. I know but you can really pull an amp out of USB No problem like nobody cares People got over this like requesting current thing like it never nobody never nobody paid attention to it didn't work out So I want to make sure that I can pull one amp through This shocky diode But I'll also select up to two amps, you know, just drag and select because I want to You know, sometimes you can get diodes that are usually You know, you're not gonna get high current small diodes, but there's like an on the off chance that there is one That's very popular. I'll just go I like to always go double. Okay, cool. So now we're down to like 2000 So the next thing I want to do is Look at the package case. So like remember I don't want sod 123. I definitely don't want the SMX series I want like a 323 or 523. I don't really need the 723, you know I think that's gonna be tougher to get currents through that. So let's get the 323 or 523 So I scroll down and then you see there's like the 123s Hold on did I make a mistake here? Oh, no No, oh Oh, there it is. They're over here. So sob 323 and 523 I'll admit sometimes I don't know why things appear in the supplier device package and not in the packages case. I Think because there's like multiple codes For these But anyways, this is fine because I want I just want these and you'll notice like now I'm I really pretty much have almost nothing left only 68 showed up Next up I can pick the DC voltage. I Actually like to have you know a hundred is kind of ridiculous, but I definitely want more than 10 even though technically my My diode Doesn't will not ever get more than like five or six volts across it I still like to have like 20 to 40 and I've noticed that usually you get Smaller forward drops When you have a higher voltage or like less reverse current leakage Although I'll say that you can't search by those values. You have to look at the data sheet Okay Next up. I definitely want stuff that is normally stocking and There's new thing where you can get marketplace items So these are like kind of like third-party vendors like they're they're trusted vendors, but they have Stock to get rid of it's which is the electronics second secondary market is kind of massive You know companies end up buying like, you know, they think like the zoo is gonna be the most popular thing They buy enough parts to make a million zoos and then they're like, oh shoot turns out like you don't need a million zoos They have all these new components. They have to get the rid of them So there's a secondary market. However in this case, I'm going to remove those just to be simple and then yeah, so this is the new thing you don't have the three individual Components in like tape real cut tape and did you real there's actually only once this is like a new update to the site Which is interesting. So Remember I'd say like, oh, you know, you can get rid of like the duplicates because it appears three times once for each Format that's no longer true And then you know one of my favorite things that I like to sort by stock going down So that's pretty handy to see Available and also price going up Another thing that's a little Different I'm gonna ask did you keep they can oh here it is Yeah, you can put in because now you can't just search for Like the price per reel, which is what I usually would do because I would kind of tell me like the quantity price instead you have to enter in Like what quantity you want to do the calculation at because of course if you're buying one die Or the price will be totally different than if you don't cut tape. That's different than if you're buying a reel The price can be like a fiftieth so Okay, so I put in five thousand and I hit return so now When I search by price you see here. It says these are four cents per and These are pretty cool looks like There's two versions of these There's both 20 volts one amp. I guess you know what I'm gonna try this compare button. I Have absolutely no idea what's gonna happen. So this could this could This could well, we're not watching the news right now So whatever is gonna happen is not worse than watching the news right now. Okay, I Trust me on this. Okay. So here. I've never I've never used this before. This is a new thing. So you can compare it This one has more stock They're both The same package They look pretty similar and wonder what the difference is one might have slightly different leakage current anyways I like this one because there's 25,000 of them and That always makes me happy because it means it's a popular part and then the product page is also changed today You can type in Like it's kind of interesting like you as you type in What you want? It tells you how what format it would ship it in so if I want like 100 It'll say look you get it in cut tape or you can get it in did you real And did you real the reason it's seven bucks more is because somebody has to sit there and like hand tape it But if you're buying like 10,000 They're like what we'll do is we'll send you 9,000 tape in real and then 1000 either on cut tape or did you real so it's like this is a little bit Different yeah, this is smart, but it's more it's just more advanced So then you can add it to your cart and then the rest of the page is pretty much the same Like it's it's got a little bit of like more of a You know flat design But they the overall usage is the same. This is kind of interesting because it's like The they'll tell you the price I think people were very confused by the fact that it's like you could get it in taping really get to get in cut tape The pricing is different people like how can the price is different? It's like well, you know, you know, somebody has to sit there and cut it Yeah, we deal with that with some of our quantities on stuff like Nampixel reels versus strips and all that Yeah, this is just the natural evolution of working with the community and professional engineers and you your site reflects it And this is cool to see it like literally real-time like yeah, and I like how you can click it's like update update update And then you can add to favorites down here, which is fun And then yeah, this was the part that we picked so you can see the NSR o 3 2 o made it into This product so I liked it. We know one amp shocky diode works Works great very small picking places very easily and it's now featured on the cutie pie. So go pick one up And that's a great search this week
