 Do you guys remember this? Remember this from over ten years ago? Some of my earliest videos? This is the computer that I had in my car so This was a computer that I bought online specially designed the pieces for being used in a car We have a little you know hard drive here, you know not a solid state This is before you really I mean solid states existed, but we're commonly used, you know I'm going back again over ten years And then I had this motherboard and it came in this case, which was supposed to be You know Kind of like a heat sink basically and shock absorbing and it has a special power supply right here That detected when the car was powered on and off and when it was powered on and off It would trigger this to shut down the computer properly So the computer wouldn't be running all the time and that was all hooked up to a touch screen like this that slid out and went up I don't know if this is I don't think it's the one this one was mine I installed one of these in a friend's car as well and then later on when he stopped using I think he gave me the screen back Very expensive little thing that kind of remind me of part of this project because nowadays if you were to do something like this I mean really you would just probably just put a tablet in your dash But if you want to do something like an Arduino an Arduino. Yes. No. Yes, and our a raspberry pi That's what I meant a raspberry pi if you want to a raspberry pi You got a power and there's a lot of noise power and I actually just got this Hey, what is this? This is this is the wiring stuff that I got for my dash cam that I was talking about in the last video Dash cam came with a wire because USB powered to plug into the 12 volts plug in my car But 12 volt plug in my car doesn't turn on and off when the car turns on and off And I don't want to drain my batteries. So I ordered this online. This cost me about 1112 bucks on Amazon There were a few that were cheaper if you want an eBay you can also find stuff similar for about $4 But this one comes with a bunch of different adapters and all the fuses we need so what is this? Let's let's open this up Let's bring this over here. I haven't opened this yet. So you guys are seeing this with me for the first time again, I just ordered this yesterday, so basically We have all this this could be clamped directly to something you got your little power converter here and it leads to a Micro USB, although I think yeah, there's an adapter here if you needed Sorry mini USB and has an adapter for micro USB So great if you wanted to power something like raspberry pi you could do that too and the way you hook this up So you hook this up you connect it to one of these adapters that the positive side the ground would just go to you know Metal screw in your car, and then this would go to one of these So what are these and this was this what comes I guess it's got all these different ones These are fuse jumpers So we have all these fuses in here that come with it for the car And then this is a little pry bar and little sticky things to run the wire with but What happens here is in your car you have fuses so what you do is you pick one of the fuses you pull it out You plug this in you put that fuse in there and the matching fuse in here So you have two fuses in here, so it's just a little fuse jumper So you can use whatever fuse so you can pick a fuse in the car There's either on all the time or Turns off when you turn the car off So you can figure that out by testing you know the different fuses or just reading the fuse label and figuring out What turns on what turns off but something about this one that I really liked is this little power brick here This little power supply Supposedly will detect it will keep the device on even when the car is shut off So if I did choose to put it into a fuse that shuts off when I shut off the car It would shut everything off But if I put it in a fuse that is on even when the car is shut off This will stay on and will keep my camera on or again if you were hooked up to like a raspberry pi or something It would keep it on but it would keep it would monitor the power and if the power In your car drops below a certain amount it will shut off the device I mean you can leave that device on all the time It but if you're out of your car for a long time eventually it will shut it off Leaving you with enough power to make sure your car will start the next morning Of course, then your alternator will recharge your battery while you're driving in theory So that's why I went with this one because it came with all these again. I could have gotten like just this With one of these adapters for like four bucks on eBay and then had to await it a month for it But on Amazon for 11 bucks I got this with this and the fuses and the adapter all for 11 bucks And I got it next day shipping which was nice. It's one of those, you know eBay is great And so is Amazon just depending on how quick you want something and I kind of wanted this today So yeah, I'm gonna hook this up and talk about it more But that's that's the basic concept. So again just to review how it works This goes to ground this will hook to one of these fuse jumpers And again, I'm just going to go to my fuse box, which is right under my steering wheel Pop out one of the fuses pop it in here put the matching fuse in here And then plug this in where that fuse was and it's now Using that fuse box both devices the original and this new device have a fuse which is important And and again It will I can hook it up to something that's on all the time And this will shut down if the car power gets too low or I can hook it to a fuse that turns on off when the car turns on Off I'm probably gonna go with the route of something. It's on all the time and let this thing shut down Hopefully it works right and I don't wake up with a dead battery. So Yeah, I'm excited about this. So here we are at my car. This is a 2016 Mazda 3 most cars have a fuse box near the engine and then one side now I am not a mechanic or an electrician. So take what I say, you know with a grain of salt If you don't know where your fuse box is usually it's it's down here or by your Love box just Google or YouTube search your model car fuse box And they'll usually be videos on where it is or look in your owner's manual if you want to go that route Mine is right here, and it actually has a little pull tab right here. It's gonna be a minute fine It says pull for fuse box. I pull that and it pops right out. Let's have a look after this Here are some of my fuses and you can see they're color-coded and have the numbers on them now Fuse box is usually I don't see one in here Well, first of all if you look at the plastic backing might be a little hard to see in the video But you can see those markings. It's telling you what each fuse is for some of them say windows Some of them say outlet so you can figure out what they are by looking at this or of course you can find Schematics online lots times fuse boxes will have little little plastic things to pull the fuses Out I'm not seeing one in here, but usually I know that the one by the engine does so let's have a look at that so here we are this is my motor my engine and This is actually just a few minutes ago. It's the first time I open this. This is my fuse box here It's usually in this area and of course what we're looking for is back here on the plastic backing again There's labels here on what all this stuff is for and this little white tools what I was coming in here for This is for pulling the fuses out those little gripper tool your car should have one of these if not You can pull them out with your fingers. It's just a lot easier to use this But I also know my car has spare fuses that is so awesome I don't think I've ever seen that before in cars where it has the extra fuses in here for at least a few of them Obviously not the bigger fuses, but that that's really nice. I tell you what I'm not promoting You know, I'm not sponsored by Mazda, but this is my third Mazda vehicle and I I love them So anyway Here is our little clip so we should be able to go into the car and pull out the fuses with that So again, I should be able to grab out one of these fuses with this little tool again I can look on the back here and see what all these different ones are some of them say window some of their outlet I can get a tester, you know Just a multi meter and figure out which one of these on all time which one is off and at this point I just want to get this thing hooked up. I can always Move it, you know up and down real easy later on so I'm just gonna pick one of these pull it out and Put in so I don't care right now whether it's on when the car is off or not Again, I'm trying to read Sunroof Outlet there's a lot say outlet. I don't know. I only have one outlet. So I'm not sure which one they're talking about here but this Top 15 amp looks like it say I'm trying to read it and hold the phone here at the same time I'm gonna go for this one right here See if this fits in here. Oh, I'm holding it backwards Yeah So I'm gonna I'm gonna put down the phone and pull that out You know, it's funny as I pulled that one out And that is the outlet the cameras hook to because as soon as I unplugged it I heard the camera make its little tone that it was shutting down because again the camera has a built-in Battery and so it detects when the power shut down and doesn't just cut the power to the camera But slowly shuts down. So this is the fuse. I just pulled out I just need to find the matching fuse that came with my little kit here and We will take that So that one seems to match that now I just got to find these little fuse jumpers find the one that that matches that so let's see I'm gonna go with Think this one here looks like a match. So these fuses should fit into here. Let's go ahead and grab those Shove one in here Again, I need a hand to do this Put the camera down. There we go. They're both seated in there nicely When I stop right there and once again say that I am not an electrician or a mechanic So take what I say with grain of salt. Also, this is not a step by step tutorial. It's just an overview There are a lot of detailed videos out there on doing this sort of thing just YouTube search Fuse tap or fuse jumper and you should come up with good instructions But filling with the camera and stuff I realized after I was done that I had put the fuses in the wrong order so fuses can go either way so it doesn't matter which way the fuse itself goes but On the adapter, there's the prongs that connect into where the into the fuse box and The section where the fuse goes in that's close to that should be the original fuse and then the fuse that goes into the top That goes actually goes out by the wire to the camera or whatever device you're powering That should be the fuse that came with your jumper or fuse tap So I did the backwards in the video. I realized as soon as I was done filming and I switched them Didn't hurt anything, but make sure you put those in the right order Also, something I didn't mention while I was filming this out there is that for the most part fuses can go either way But when you're installing installing a fuse tap like this There is a load side, which is usually the side that's on the far side From the wire that's coming out of it So you want to do you want to get a multi meter and figure out which side in the fuse box is the hot side I Believe and again, I'm not an electrician that if you put it in backwards everything will work fine But if you blow a fuse you're gonna blow both the fuses rather than just one I think it's the only issue, but it seems like it could be worse Anyway, make sure you know which side is the hot side and the hot side will be the side of the fuse Jumper that doesn't have the wire coming out of it in most cases, but look up the information for the fuse Tap that you get and here's just a visual on what I was saying So this is the little wire tap jumper and this is the fuse it came with So when you pull out the fuse in the car the fuse from the car should go in this bottom one The closest to these connections here and then the fuse that came with the tap should go up here Because that's going to control where this wire goes in the video when I first did it I did them backwards and quickly realized that didn't hurt anything, but there's that and then again, there's the hot side and again check with your Your wire tap, but there should be a hot side which should be the side that's furthest away from the device So this is the hot side So you'll need a multi meter or some sort of detector to check your fuse box and figure out Which side is hot because with a regular fuse you plug it in it doesn't matter what side you plug it in But this I guess if you put it in backwards So when I'm plugging in this car if I plug it in this way rather than this way It's going to I guess it can loop back and burn out both fuses if there's a problem rather than just the one fuse that it needs to So yeah, again look up the information for what you buy. There's a lot of Good videos out there on YouTube. This again is just a quick overview, but I wanted to Make you aware of this so and then back to the video and Hopefully this will fit back in this little compartment here I'll be able to plug this in where that fuse was sure enough I was able to plug it right into there and as soon as I did I heard the camera come back on because it's still plugged Into the outlet over there, but now we have this little end here so we're going to take the rest of our connecting wire here and This positive terminal should slip into there And then this ground should just go to a bolt on the car on the chassis of the car somewhere And then I can run this wire up to the camera Just you know just by pulling back the plastic stuff on the car and running it You can pull this down, you know and just slide up just like I did on the other side of the car with the current wire and then Hi, and then and then it should turn on and off when the car turns on and off and It should be on all the time since it took to the outlet was on all the time, but this particular wire At least Advertises that it won't let your car battery die that when the power gets below a certain amount It will turn off the camera or whatever device you have hooked to it Which is great Which means that thing will be recording even when my car is parked somewhere until the battery on the car gets Hello, I don't know how great that is for the car battery Anything there's things constantly running again. I'm not an electrician or a mechanic But it won't let the battery drain completely which I know with lead acid batteries It's not a good thing to let them drain completely It should make sure there's still enough power in the battery to start the car and then again Your alternator will recharge your car and again I'm doing this for a dash cam but what when I got this where I thought wow This would be a super easy way to hook up something like an Arduino Or if you were did want to put a tablet in your dash You could use this device and then your the car will keep charging the tablet So the car gets to a certain amount and then it turns off But then the battery in the tablet would keep going so and you know, I mean this this car already has You know a dash screen which is running Linux as I've talked about in previous videos And I have a root shell on and I do someday hope to do more with but again Right now it is summer in Florida and it is hot out here So it's not fun sitting in my car playing with this although I just need to get to my Wi-Fi which it does have Wi-Fi Anyway, that's a whole another subject. Anyway, I'm going to you know Connect the rest of this wire up and run the wire up and hook it to the camera But everything should be good and now I have the camera hooked up to the same Fuse that it's hooked up to before So it's gonna be on all the time until the car battery gets to low But hopefully again this device will keep my my car from completely dying So I'll have the camera recording when I'm driving and when it's parked somewhere So if someone tries to vandalize or tries to break in my car and doesn't because they break in they'll probably just grab that camera But again, so you know, I spent 11 or 12 bucks on this wiring unit, which could definitely be used for other things And I have all these extra little fuse adapters too, which might come in handy. I'll hold on to those But I didn't realize it's gonna be this easy when I first thought I was gonna hook something up in the past When I've hooked up stuff like this, I've wired into the cigarette outlet and I just wired directly into it Which probably isn't the best thing you probably should probably going through a fuse like this so Yeah, this seems like it's gonna work out and it's super simple, you know I didn't all I had to do is pop open that fuse box I'm gonna have to you know Loosen a screw to put the ground on and then running wire and cars like this if you've never done it It's super simple This wiring came with this little blue thing the camera actually came with a bigger nicer one You can just do it with your hands sometimes or screw jar, but you might scratch it using the plastic pry tools You just you don't you don't need to pull anything. So like an example like right here, you know You pull it you run the wire in here. See how my fingers go in there You just run the wire there and then you're up over your window all this pulls down just enough See I'm sticking my finger in there. You just run the wire along there. It is nothing to take apart really so Yeah, I'm excited about this. I did not know that the vices exactly like this. Like I said, I knew they made You know USB Connectors that you could connect to your battery and stuff. I didn't realize they had these little fuse jumpers. These things are awesome So anyway, I hope you found this useful and again, I'm just looking up the dash cam But now I might hook up other things in your I mean I already have okay I should pull out that computer and see if there's another input Maybe I could hook an R2 we know to it and have two of the next systems running in my car Anyway, I thank you for watching.
