# AliExpress unbagging joy - Car diagnostics, camping lights, beacons and connectors ## Метаданные - **Канал:** bigclivedotcom - **YouTube:** https://www.youtube.com/watch?v=7AiXHjTexSo ## Содержание ### [0:00](https://www.youtube.com/watch?v=7AiXHjTexSo) Segment 1 (00:00 - 05:00) It is time to unbag another massive gray sack from AliExpress. And this time I'm going to have to take all the stuff out and carefully remove my postcode off it because they've just started adding my postcode on. So I'll just get everything out onto the bench and then we can start exploring. Okay, it's not too bad this time. So nothing too precarious in the show. Maybe some barcodes that will narrow it down to the local uh town, but that's about it. So, let's get into this and see what marvelous devices I have bought in my impulse purchases. Okay, so this is the little mini self adhesive heat sinks. Are they all stuck together? The tapes. You'd have to split them. Hold on. Let's do that then. Let's run a knife across the back or between them. Hold on. Just get it over here and [ __ ] What is the best way to do this? Sh it. Is that better? No. Uh anyway, you're going to have to slit these apart yourself apparently because they are little mini heat sinks with thermal rated tape in the back apparently. Uh that lets you stick a heat sink onto a chip for extra cooling. Let me zoom down this so you can see the heat sinkiness. Little ribs for your pleasure. There you go. Well, for your chips pleasure. That's quite handy. I could almost I wonder how that would affect uh the TP 4056 type charging chips. I wonder if they'd benefit from something like this cuz they do get hot sometimes. Okay, I'll stay zoomed in a bit and we'll choose this might be connectors. The look of it slight pause. Oh, I know what these are. Yeah. Okay, this is male and feel female connector. I'm going to zoom out just a little bit. Male and female connectors, but using they're based on my sort of preferred connector system. I didn't know they made them in this style. Uh but you can actually it's designed as sort of uh flying plugs and sockets. That's quite interesting to know. That is interesting. How well do they clip together? Well, they clip together quite well. So, it comes with the male and female parts. And uh pins and the socket contacts. And the socket contacts look like my standard um the standard what I call the Molexi connectors. I'm trying to remember what the name of those are. Uh was it on the packaging which I've just binned. Uh let me just go and check that. They are KF2510. It's a series of connectors. Um kind of tempted to actually make one of these up and see how well they go together. Um I'll do that because I've got the crimping tool for these the crimper right here. So I'm just going to get some bits of wire, strip them, and I'll put them into this and we'll see how well it goes together. Okay. So I'm very used to doing the female connectors here. So I'll just pop this in here. Put it into position. Close up very gently on that. Get the Get one of the red wires and stick it in to the crimping area. Ratcheted it. Looks good to me. Okay. Now, what I've not done before, hold on. I'm just going to have to get my head around this. Uh, so we've got the long bits going in there. I've never actually crimped one of these ones before. This should be interesting. So, let's close it down. That get it to roughly the same position. Get the red wire in. How's this going to go? It's going to be very different to what I'm used to. That doesn't feel too bad. That looks all right. I think we'll find out when I try putting it together. Right. I'll do the black ones and then we'll put them into the connector and see how it goes. Okay, they're crimped. Let's see if I can screw this up now. So, I shall put this one in here as I usually have my own preferred arrangement. And that clicks in reasonably well. So, this is the female side. And they've latched in. Okay. And then let's just make sure I put this round the right way. We want to get the matching black connector goes in here. Where's the latch? Which way up is that? I could try putting in both ways around. Is this tempting fate? So that is the Where's the ratchet there? So the little end at the bottom. Not sure actually which way around this goes. I think this may be one of those trial and error ones that I suddenly screw up a connector. Uh but that's what happens. So let's try popping it in like ### [5:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=300s) Segment 2 (05:00 - 10:00) this first. Is it going to latch like that? It's not really going in. Let's try it the other way up. Did that latch? Yes, it did. Okay. So, the latch goes up the way like this. You're seeing me try a connector out for the first time. That seems to work. Okay. The latch goes up in the direction of the little uh the little recess there. And then theoretically, I should be able to just plug these two together. How's that going to go? It went. Okay. So, there we go. Uh, first test of a new connector that I've never used before. Excellent. That went surprisingly well with no wastage. Okay, let's stuff that back in its bag. When you start using a new style of crimp connector, you have to do a little bit of rehearsal and practice with it because uh the first time I used these connectors, I found it quite frustrating. But now I just munch through loads and loads of connectors. Thousands. Many thousands. Okay. What's the next item? Uh the next item is a treat. This was suggested because someone bought one, but I think they said that theirs only had four of the filaments in position and uh there were spaces for the other ones, but this is a rechargeable light. There's a button. Let's press it. Okay, that works. Oh, that's quite bright. That is ferociously bright, but it's got the filaments all the way around it. I see it's also got what looks a focused beam. Click. Oh, pulse with modulation. Okay. Click. Uh, more pulse with modulation and off. So, how do I get the end one on? Double click. No, that's just working my way through those again. Press and hold. Yes. So, press and hold brings on the beam. Uh, and press again. Pulse modulation. You can see that strobing the camera. Hold on, let me just uh It's a slow pulse of modulation, but it's not too visible to the naked eye. It is very visible on the camera, though. Interesting. And it's got the little charging port here. Oh, and the other thing, it's got a little rubber flap. How are you supposed to put that on? So, there's a charging port. USBC. Uh, and then this little rubber flap presumably goes on like that and goes into that to make a little token gesture reflector type thing. Okay, that's reasonable enough. Instructions for use. Maybe I should have read the instructions first. No, it's got them in many languages, but it's not got them much in the way of instructions, has it? Oh, it's got lots of languages. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 instructions. In English, it says instructions for use. This product is a general merchandise suitable for daily life in a variety of scenarios. Please read the label carefully to understand the product information. Follow the instructions to ensure proper use. Pay attention to the product to extend use time. That's not really instructions, is it? That's just a box ticking instruction sheet. But anyway, that's quite nice. That is quite stylish. It's a bit weird, the floppy cover. Uh, does it open easily? Hold on. I'm just going twist it. I'd like to see I'm guessing the batteries down the middle. Uh, they've also got wiring down the middle to go to the bottom, though. So, is that going to be an 18650? We can take this apart at some point. We can find out what's in it. But that's quite neat. Okie dokie. It won't go in its box anymore. Right. Because I've put the flap on. Right. I'll put that over there then. Next. Anang. Oh, I know what this is likely to be. It's going to be the other battery tester. It is. Now, it turns out Julian Isa has featured a few of these battery testers and they have their quirks, but I shall do a deep dive in one at some point and reverse engineer it completely. But the idea is that it's the if it's the one I'm thinking of. It's the LCD display battery tester, but Julian says they don't put a load in the cell when they're testing it. Hold on. There's a little uh there's a freshly charged 1. 2 volt cell. Oh, how' you open this? Righty ho. And we put it on. And it says, get the connection on here. Uh 1. 4 volt. ### [10:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=600s) Segment 3 (10:00 - 15:00) That's reason enough for a freshly charged nicome metal hydride cell. Okay. Interesting. Right. What What's next? These ones are a matched set. Can't remember which is which. But we'll find out when we open them. It's an LED bulb. I think it's a very fairly generic picture. What's it going to be? It's filament bulbs. Now, I seem to remember I brought a one watt, two watt, and three watt. I presume this is the one watt cuz it's got one filament. I think the other ones had multiple filaments. And I think these are 240. That one is uh four filaments. And this one has two. Is there anything written in the box to give rating? No. It's got all the little boxes that they could have ticked, but they haven't ticked them. I think these are 240 volt. There's one way to find out, and that's to stick them in a socket and see what happens. I'll just see if I can find that right now. Okay, change of lighting to facilitate the hoppy and also to make the bang more visible. Uh, screw in. This is the one watt one. It says 7 watt. It's going the right direction. I wonder uh. 9. Is that a resistor or is that a linear current regulator? Interesting. Right. Next one is the 2 watt one. Well, that's very harsh cold white. And it says 1. 3. So they're roughly going 7 watts per watt. Uh power factor. 3 is very different. Okay. And this is the 4 watt one which is not making a good connection or is having moments. 1. 7 watt 0. 9 power factor. That also suggests a resistive type of dropper. But it's interesting the other one didn't. The two one. Okay, watch your eyes. The light is about to come back. And the next thing is this monstrous thing. Honestly, it didn't look this big in the picture. I was expecting something that size. And uh here it is. It looks like a rectal insertable. This is a fishing light. Again, I've featured a few of those in the past. But what type of batteries does this one take? It takes D cells. Okay. Uh, one moment, please. Dels removed from another product. Old D cells. What is there a date code on these? March 2022. So, they're not that oldish. Let's stick them in the anang and just see. Does it even manage to bridge this? Yes. 1. 49 volts. That's good enough, isn't it? It's fine. Let's pop him into this spring. Spring and screw this on and see. I'll warn you in advance. It may strobe. I'm not really sure what this is for, what it does. So, we're screwing it down. And apparently, it doesn't do anything. Excellent. That's a good start. Okay. Uh oh, hold on. There's this contact here. Isn't that supposed to be up on here where it makes contact with this? Unless that pushes down into there. Hold on. Does it push down into there? It does. Hold on. Let's just shove it down by hand. Uh, no. Nothing. Unless Is there a polarity issue? Is there something I don't know here? Hold on. I'm just going to try this in the bench power supply. All right. Apparently, hidden inside here is a light sensor. So, uh, it does flash. So, let's get this screwed on again. And hopefully when I turn the light off, and I'll not change the exposure for this just in case it's super bright. Uh, right. Tell you what, uh, I'll take the exposure off. That's all right. projects a little star of light out in all directions. That should last a good length of time, particularly with the D cells. It's about to get bright again. And the standby current seems to be super low. That'll be interesting. I think we'll explore what's in this module here. The last one had some interesting circuitry. It used a little boost converter to step the voltage up to 5 volts. But quite interest construction and the functionality that you can theoretically ### [15:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=900s) Segment 4 (15:00 - 20:00) change these LEDs if you wish. Okay. Useful to know. Right. While we're on the same subject, we got another one of these here. This one looks though it may take the double A. It looks as though it's got the same circuit board arrangement. Yeah, same little circle. So, I'm going to guess this more or less does the same thing but with double A's. Let's uh pop some double A's down into it. That's a very weird way. They've got the uh the spring down the bottom of this. It's kind of like it's I'll show you in a moment. I'll stick a light into it and you can see. But theoretically, this is blue. It's flashing. It doesn't seem to have the light sensor. It just flashes. That's reasonable enough. Um okay. Excellent. I'll just uh unscrew it. I'll show you the contacts in there. It's quite odd. get the batteries out. Makes them a bit stiff. Uh we'll zoom down onto this. And I'll put shine a light into it to show that the spring wire in there comes up and then just hooks into a little dimple in here just to stop it being pushed right down inside. But uh I guess really it just squishes out the way. So you're going to have to whack that to get the batteries out. Okay. Right. It is what it is. Excellent. I'll just shove this in here. They're quite nice chunky little things. I shall put them out the way and we'll take a look at this LED filaments. That mean I've got two packs of LED filaments here. Let me zoom back out again. These ones. Did I buy white filaments or are they a different color? Thought I brought colored ones. I think I did. Let me uh get the bench supply on and I'll turn the voltage down to a sensible level that's not going to nuke these filaments. So, let's to turn it down to about 2. 7 volts. What way around do these go? Oh, there it is. Oh, it is. It's green. Green filaments. It's nice that this particular seller is selling them in the little box uh so that you don't end up the pile of broken filaments. I was weeding through some stuff recently and some of the stuff I was weeding through was a box literally filled with broken filaments. It's almost as if they'd sent every single one pre-broken from the factory. Maybe in the hope that people would just say, "Oh, well, it must have got damaged in the post. " These ones, I'm guessing from the fact it's uh clear that these are blue filaments. I'm trying to work out why I bought these filaments in the first place. They're that sticky siliconey coating. Okay. Is it going to be blue? Get the polarity right way around. The long lead I presume then is the negative and the Oh, there we go. and which side the LEDs are on one side of it. So, it looks brighter than that. So, I'm just not getting a great connection here. Uh, and then normally the phosphor makes it look evenly lit. But in this case, it's just relying on uh reflection and shining through the ceramic. Okay, that's nice enough. Cheap filaments. They used to be so expensive when they first came out. Now, we're on to the bigger stuff. The look of it, we're on to the big boxes here. So, let's open the first one, which is mashed. How does this open? It's taped. Not that it's really needed. I could just burst the end open. It already has. It looks as though it's been stuck together a couple of times already. Oh, and this is a vehicle fuse tester. Now, I'm wishing I had some little vehicle relays. I do have vehicle relays somewhere. Um, I have vehicle relays on a little uh power box that I could have taken a look at. Uh, I'm just going to see if I can find that. One moment, please. Okay. Well, I did make a video about an entire relay box stuffed relays. I do not know where that is. But anyway, you hook this up to your car battery to give it 12 volts and you stick a suitable relay in here and then you choose if it's a four pin or a 5 pin relay and you press the button to test it. And I guess it's doing something more simple more than I thought it was just going to be a clicky, you know, just powering the coil and just seeing if it changed over between the contacts. But I wonder if it's got active electronics in it. I suppose there's one way to find out we could open it. Yeah, let's open it. So, I'll just turn this off. Turn the bench supply off. Uh, there's a ### [20:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=1200s) Segment 5 (20:00 - 25:00) couple of screws here. We'll whip them out and we'll see if there's anything obvious inside. Is it going to be anything fancy? I can always order some relays up to test it when I make the video. Now, is this going to be has this got hidden screws under the front? I hope not because that's something I don't want to actually go any further if there's any risk of me breaking it before making the main video. Any other screws hidden here? Is it just clipped after that? Where's this sputter? Oh, it does look like it is clipped. That's good. We are getting to see inside it then. Right. And we've got a couple of screws here. Let's get them out. Spoilers. And that will have the relay contacts, probably loose relay contacts on it. And circuitry. Oh, blimey. Uh, okay. So, there's uh there's quite a lot of circuitry on that. which is unexpected. I'm guessing it energizes the relay and then it checks the state either way and then just gives you a yes or no. I mean, you could just do that with two LEDs, couldn't you? And just click the button to actually energize the coil. Unless it does it continually in the background. I don't know. We'll find out. I'll get some relays and we can test it and then uh reverse engineer it and see exactly what it does. Right. Tell you what, I shall put this back together again. Oh, sweet. It turns out that there's no end to the uh screws because they've actually stripped the plastic in the factory. Excellent. Good job. So, the next gadget is another automotive device of unknown uh use. It is a cheap um OBD analysis unit. The only way I can really demonstrate this is by plugging it into a vehicle, which isn't practical at the moment since it's thrashing with rain outside. Um, and it's also pitch black. It's middle of the night, so I'm not sure that'd be a good time to do it. But, uh, this unit, you plug it into your OBD port of your vehicle, the onboard diagnostics, and theoretically, it can then run lots of tests on your vehicle based on its internal database. And this thing's got a colored screen. And the fact it cost about £5 makes you wonder about the quality. But uh what I want to do at some point, I've got an old car outside. I want to plug uh several testers in and actually just see what fault reports they can come back with. Uh this one looks as though it's got molded plastic screws for fakery. I could be wrong. Maybe they're real. They must be real, surely. Are those fake screws? Yes, they're fake screws. It's just clipped together. Fakery. Uh, but yes, who knows what that's going to be like. Okay, how's the time in this video? Oh, we've got time for some other items. Let me go and dig some other stuff out that's arrived. Another light. I don't think I've featured this yet. The pine cone lamp uh out loose from a box because I think I was traveling at the time when this arrived. But this thing is another dangly light. Look at the little all the little brass rivets they put on just to give it that look of quality. Uh it takes USBC charging again. And this time we've got uh three filaments or clusters of LEDs pointing down the way for a wash light. Well, they're both wash lights, aren't they? Hold on. Let me turn the light off and we'll see what sort of beam pattern this has. Okay, so uh actually this is both the sets of lights. Hold on. Let me turn it off. And turn it on. This is just the what you might call the wash light. It's fairly widish. Yeah, it's puts out a fair splash of light all around. Then this one points it down the way. And then the next button, oh, alternates between them. How useless is that? That's spectacularly crap. Excellent. So, the other thing I've noticed it has, if you want it as a lower level light, you can press and hold and it will dim this down. It will blink out at the bottom just to show it's reach the bottom level, but that's the bottom intensity. And then if I uh press and hold it again, I think this works for the other lights as well. So, if I click to that, it will also dim down. Does that dimming also then apply to all the lights? No, it uh resets Yeah, the cross color changing is just odd. ### [25:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=1500s) Segment 6 (25:00 - 30:00) What? So, warm white, cold white, the crossfading thing. Oh, and then both on together. Okay, interesting. Watch your eyes. It's about to get brighter again. I reckon they've got a cylindrical battery. 18650 tucked down the middle of this light. And it's got this rubbery thing in the top. Anything else? No, that's more or less it. Is there anything I didn't see? Retro chandeliers, it says. Well, that it's a retro chandelier. Yes. Okay. Running time 5 to 40 hours. That's probably wishful thinking. And it does uh show you apparently the battery status. Green light 15 to 100%. When it gets to 5 to 15%, it's red light to show it you need to charge it. And then red light flashing is less than 5%. Charge immediately. Right. Let me go and see if I can find another item. Oh yes, these are going to be good quality, I'm sure. Not really. Sometimes it's worth buying these little kits of these for just the actual crocodile clips. And then you could buy them separately. They're little jumper cables, but the quality is extremely random. And what I want to see here, I want to pop one out. Let's pop the yellow one out. Stick it in my finger. They're slippery inside there. They're slipping around. Uh and we'll take a look inside and see. Is it the usual crap? Yes, it is. So, what they've done here, let me uh get this up close. I'll just focus on this right now. They have done the usual thing. They've literally stripped the wire and they've folded the few strands inside it back and uh then they've crimped onto the plastic with the strands trapped against the metal in a sort of haphazard way. And although it grips it nice and tightly, it's a terrible connection. Uh let's also strip this right now. And we'll see for this big thick work. Ooh, so thick. Uh let's see how thick the uh let's uh come up to a focus level. Let's strip it. And it's literally it it's just it's the thinnest tiniest amount of wire they could get in there. It It's crap. Uh but that's okay. They have their uses. And of course, you've got a complete set of colored crocodile clips. So though, to be honest, you'd be better just buying the crocodile clips on their own. Let's uh focus back down to here. Focus. Focus camera. There we go. And next gadget. They're crap. That's expected really. Uh if you ever you're using little sets of these and they seem to make an intermittent connection, it's because they're crap. They're almost always crap. Uh, you can make your own. So do the wires. Use thick cable just it's better altogether. And the next item we quickie sneak a little extra quick one in. It's another OBD reader. Is this How is this put together? Is it I think that's glued together. This might be quite destructive to open. in which case I probably shouldn't open till. I'm making the video about that. Uh my plan is to plug lots of random ones into the car until it ceases to work permanently, but that's okay. Uh but this is another one. It's the Bluetooth OBD reader. The sort of Elm 327 is that they call it. Um and uh it uh then connects to your phone. The torque app is particularly recommended and it lets you read various statuses of the vehicle's engine management system and look at sensors and stuff like that. Uh quite interesting things. There's a horrible story behind the original concept of the Bluetooth uh readers, the ELM 327, Elm 328. It's one of those. And uh does it say in the bag Elm 327? Uh, the reality is Elm is a British company. I don't know if they're still trading, but the guy wrote software, microcontroller software, and then sold the pre-programmed chips and people built their own little Bluetooth units. And unfortunately, he didn't lock the chips. Maybe just one of the chip, maybe them all. But, um, it meant that someone copied the software and made it available online. and uh it got mass copied uh by the Chinese became the famous Elm 327 Bluetooth vehicle OBD readers. Uh so the moral of that story is always lock your chips. The microcontrollers have a facility to lock the chip. It's not completely infallible but um it will avoid people easily nicking your software. So there we have it. It was a mockly collection of interest things, an over complicated relay tester. Uh the useful little heat sinks, lights, nice lights like this little light looks quite good. A new connector to me. Um [ __ ] connectors. Uh ### [30:00](https://www.youtube.com/watch?v=7AiXHjTexSo&t=1800s) Segment 7 (30:00 - 30:00) the OBD reader and the one with the LCD display, battery testers and LED filaments. I mean, it's all marvelous stuff. --- *Источник: https://ekstraktznaniy.ru/video/39548*
