 The greats are trying to bond I did you keep a pretty single weekly data hopes you just you find things on did you key? Thanks. Did you key for making this segment possible? Lady, you know, what are you looking for this week on did you key calm? Okay this week? I saw on the zits some folks were chatting about RCA jacks, and they wanted triple RCA jacks. This is a dual RCA jack for stereo audio And RCA is still a very popular connector. It's really basic, but it works really well kind of foolproof There's color coding, you know, and then you can match it up to The cables so like you know, this is an example the cable has the yellow and red and white coloring That lets you know that this is video and then left and right Although I don't I never remember maybe red is right and white is left. I don't remember. Maybe it's the other way Stereo audio. Oh, yeah, R is R is red so that's a good way to remember right is red and left is white and This is NTSC your pal Component video composite video But some people like oh I want to have something for Component video to always mix up component video is not the same as composite composite is one Where all the sync and all the color data is on one wire And it uses like color bursts and like you know extremely amazing complicated And slightly lower quality way of transmitting audio video But if you want better quality video and this was in particular for retro computing a lot of video game systems Before they had HDMI to get good quality. You could maybe have component And component even though it says RGB. It's not necessarily red green blue. This is actually Y PB and PR which are the sync and Luma for a Better quality HD video, but it's still like on an analog Stop connector And then there is analog it is actually possible I will mention like, you know, I was like, oh, this is component video, but RGB Analog does exist in some VGA. So sometimes you will see VGA connectors and they'll come out to Analog red green and blue and then sync is on green. So that is it is possible to have it be True analog with like the analog levels on red green and blue But anyways, you can use it for either still very comment on Older pre HDMI displays better quality than Composite Not as good as true digital DVI or HDMI. Okay, so you want these connectors But we want one that's triple not dual although you'll see you can also select dual and what's nice about these is They come as one piece They're molded together and this makes it easier to place because you place them at once They're always like perfectly even because they're plastic mold together and also These plugs take a lot of strain like it's very easy to like wedge them and pull them and Twist them not twist but torque them And so having a lot of mechanical strength is good and having all three connected together on a plastic piece Not only looks good because of evenness But we'll give you more mechanical strength because you can have a mounting tab for example or each of the You know each one has to Contacts the ground circle and the data or analog signal center You now have six, you know four or six contacts that are giving you mechanical Torque protection to get instead of just one one RCA Jack will absolutely torque right off especially if you have You know a younger person who is like still learning how much torque you can put on something So let's go to digikey and look at these so these are called RCA connectors But the category is going to be it's interesting even though in this case we're using it for video for Component video it will be under audio connectors because it's historically used for audio and then it kind of got like repurposed for video So if you even though it has you know your standard That was like a three point five millimeter or quarter inch Jack If you go here, you'll see that it is in fact RCA connectors. So there's Bunch of different configuration again, these are Very old connectors and they're very common. They're still used quite a bit I will say don't use them for power. I've seen people do that. Don't use them in power Use them for like you can use them for some RF signaling Low frequency or you can use them for audio or video You can have vertical sticks right up Horizontal this is extremely common the right angle like I said and they come in various colors This one is nice has a plastic protector. You'll see there's the two nubs in the front That will sink into the PCB and give you mechanical strength This has, you know, three big contacts you would solder in instead and then you can do get into the You know multi multi-pack style. So this is stereo left and right, but the vertical Dual stereo left and right, but you know input and output maybe two channels And then various colors yellow is common blue I guess for RGB or for that Composite whites is common black. You'll see like, you know Black white red yellow green and blue. I've seen like some other colors once in a while. We're not gonna get pink unfortunately, so what we're gonna look for is Triple with red green blue coloring so first off, let's only look for active and Normally stocking so you only look only for stuff that you can kind of get okay, so now we want to select We're gonna have through hole because we want it to be coming out of the PCB and we want Let's say right angle, you know coming out to the side But this one doesn't say vertical. So I'm gonna select anyways because it's unclear Which way it is sometimes like the categories aren't complete A couple different manufacturers Uh These are looking good. These are still all the singles so You know if you look at this dual because sometimes you're like, how do I select that? I want three and it's like there's a dizzying number of You know setups here. So on this one, it's two sets of two conductors Three contacts the contacts is a little confusing I would go with the two sets of two conductors because each connector has two conductors the ground and the signal Um And I guess the three contacts what that means is that the grounds are all shared I don't really need that I don't really care too much and then you can also of course search my insulation color That's another way to do it. But let's just look for the three three sets of contacts um, so three sets Uh three contacts five contacts or six. So basically, you know, are the grounds shared Or not uh looks like on this one I don't understand how it could be three. Oh, no, sorry. This is three conduction I want three sets of two conductors part three sets two conductors each six or nine nine Not sure how you can get nine contacts out of here, but we'll we'll find out. So let's apply and see Okay, so it looks good. Uh, so there's this one. This one's looking very nice Uh, I wonder which one has nine This one has nine. I guess we'll see what's up with this one. Um red green blue So this one is kind of what we want, but it's not in stock. This one Interestingly enough, uh is here, but it looks monochromatic Um, so let's click because sometimes there's multiple photos And we can see what's up here. Let's go to the 360 And wait for it's loaded Okay, so this one is uh red green blue and we can see Oh, it looks like there's is there a switch or maybe there's just dual contacts Let's see if there's what's going on in here There's no Oh, there's a switch. Oh, that's actually really nice. You know, I didn't notice that before so this one has nine contacts There's actually a switch so you can have the signal grounded. Um when nothing is plugged in. Oh, this is a very nice connector So yes each one Over here has a switch inside. You don't need to use it, but it's there if you like it Uh, and this particular part number is pj. I am 3x great 1 u o 3 x 1 u o 3 x Okay, so this one the only thing that this doesn't have is the gold plate. Apparently there's a gold plate version But nickel plates probably fine, too Um, so yeah, this is a very nice connector Nicely than I even thought I didn't realize that I had a switch. I was like, why is there none contacts? I just switched built in so this one This is going to be really nice. This will definitely do the job No matter what I like that you can ground the inputs when they're not connected Uh, give your analog input stage a break. So this is my pick From switchcraft pj r.i.m 3x 1 u o 3x triple rca
