 Let's hit, did you key site? All right, Lady Aida, what, uh... Oh, so, um... What are we doing here? Okay, so, you know, we talked about how I want to use AAA batteries for this design, not lithium polymer. And what's really nice about using alkaline or nickel metal hydride AAAs or AAs is you can get off-the-shelf battery holders that are inexpensive, very durable and easy to add to your design. They come in like all sorts of different arrangements. So, so, let's start searching on the didgy-key site for battery holders. And if you see in the Aida Fruit Kits, you'll know that we use like nine-volt holders, AA holders, AAA holders of all sorts and sizes. I just think they're really great and they're so much easier to use than lithium polymers. You can toss these batteries in your bag. You don't have to worry about them shorting out. You don't have to worry about like thermal, you know, management. They're really solid and reliable. So, let's search for battery holders. Now, there's actually gonna be a couple different kinds. Yeah, there's accessories and chargers, but, you know, you'll see here there's, you know, 1700 items under battery hold clips and contacts. When you go there, you'll see that a lot of them are actually coin cell holders. Like, these are really, really common because even though I like alkaline battery holders, most people actually who are, you know, assembling electronics, they tend to have battery coin holders. They have coin holders, not alkaline battery holders, and then they have maybe like a lithium polymer DC power for the primary power. Anyways, there's a lot of coin cell holders. We're not looking for coin cells. We're looking for something like this, you know, something that has these springs and the clips for the batteries. So, let's go to the top to only look at active designs. And we're gonna only look for triple A battery. It looks like you can also get like, you know, quad A. There's all sorts of different types of batteries. There's half double A. There's, you know, the coin cells of every type. There's 18, 650, so it's like a Panasonic lithium ion battery holder size. So, you can, you know, you can get like a wide range of different types of battery connectors, but I'm looking for triple A. Okay, so under triple A, you can now get, you know, there's the single one-offs. There's ones with wires. I want something like this. You know, I like to look at the photos to get a sense. This is, I want something like this. I want something with PC pins that can go through the PCB and solder in place. Another design that's kind of nice is this. It's four pins, but it looks like you can kind of arrange the, you know, the polarity of the battery holder. You know, there's a couple of different versions. This one has a difference of a spring. That's like a coiled spring. It has like a leaf spring. So let's go and look for two cell because it's two triple A batteries to give me about 2.5 volts. And you have a couple of different mounting types. That's another thing to watch for. So, and some kits that we've done, we use wires. These are kind of nice because the wires are tinned. You can solder them in and this is good if the holder is gonna be a little bit apart from the PCB or maybe mounts on the chassis in a different way. And there's mounting holes. There's the PC pin. There's another version with wires. I'll show you a couple of interesting, there's also like components. So if you're 3D printing a design and you want to really have it be low cost and you want the battery to be part of the 3D printer injection molded design, you get just the spring contacts, which is kind of neat. Like these are just the contact pieces that you would put into your design and then have the batteries press against them to hold them in. You can get them with looks like some kind of like Molex connector on the end. These are some like pretty sweet metal keystone connectors. I've used these once in a while. They're extremely durable. Like it's one, we really have to get the battery out once it's in. And even though it's all metal, you can see that there's these washers that keep it isolated. So it's even though it's all metal, it is electrically isolated. This is also an interesting type that I've used before. This is the slimmest battery holder. So if you're like, I need to have it be the smallest amount of space without like the extra plastic. These end to end ones work really well. Here's another one with a connector. Okay, there's also ones that are enclosed. If you've seen like I think our TBGON kit, it has a battery like this. So this battery holder, you know, there's a slide clip that goes over it and protects it. So it's a little packet. And a lot of our projects with a circuit playground express will have a connector like this. That's kind of it. There's a couple of different variants. You know, you can get ones that are open and closed, more that have like a little slide connector. You know, this one has gold tabs, but what we really want is PC pin because we want it to solder into the circuit board. And there's a couple of different options. So you can sort by price. And you'll notice that there's pretty much like two suppliers that are really common, Keystone and MPD. And they make pretty much the same things for the most part. Like if you can find it one with MPD, you can usually find it an equivalent one with Keystone. So for example, this one's a little bit less expensive. It's, you know, $1.22 per in individual quantity. But it's basically the same as this one. So I like to have alternates, especially for connectors because I've noticed that things like this happen. You want to get the connector and it's like suddenly out of stock and you're like, oh my goodness, am I screwed? If you have an alternate, it's not a big deal. So as you're speccing at battery holders, try to have like two or three different options from different suppliers. And then when you get samples, make sure they all fit in your design. That way you can switch between the mall because unlike components, the mechanical outlines and like the mounting pads and the holes may vary a little bit. So you just want to make sure that you can, like this one has the two mounting holes in the center and this one has them on opposite sides. So you may want to have extra holes so you can support either version. This is another nice thing that you might want. These versions have a little red, like a bookmark. It's a ribbon that you put underneath the batteries and then when you pull the ribbon, it pops the batteries out. I ended up not needing something like that. I basically just went with this Keystone design. It's very inexpensive. You'll see once you get to like the 500 or 1,000 quantity, you're gonna get like a pretty good price, under 75 cents a piece, which is great and easy and they're really easy to work with as well. So here's the battery holder. Let's now pop back to the overhead. So this is the battery holder. So this is the one from Keystone. You can easily pop in the batteries and then on my design, you just have the two large pads. Let me turn this off. You can slide the battery in and I'll just kind of hold it up against and turn this on and now it's a portable badge. Cool. Nice. All right and that's the great search.
