 Hello everybody and welcome back to my channel. I'm sorry for the delay in this. I just had a bit of a mixed up weekend managed to wreck my Linux installation and I still haven't managed to pull my Windows it's not a petition. It's a separate disc inside the laptop. It's got two hard drives and I've not managed to get that back, but yeah, and it's quite a vex me a little bit, but we're back at this Now let me just check that what we got on is on. Let's have a look at what we got so far So let's just do a little look here. So you can look at where we got to I'm just gonna bring that upon the screen here Just bring this in a little bit Bigger so I can see it easier No, I don't know if you can read through the boiler and stuff in the background. I'm sorry about that It's not getting a bit too loud because it is quite a loud boiler system, right? Let's What can I do about that letting you look at that day? I'll put it up on the screen. There we go. So this is schematic and We will we are into where VR one is the 2k VR one Okay, so you can see that's pretty much dead in the middle Okay, so we're gonna be connecting a 1k To the To the side of that and of course as we use the wiper it's gonna Be adjusting from one side together of that 2k that 2k part, so Let's just do it as it is on there Let me just check that that's a 1k. Yeah, that's a 1k Now Let's have a look what we got. We've got this boy becoming out here. We've got the three in there No, I know it's been requested we go a bit, but the lenses on this camera, unfortunately Not all in the same place. So you can see that. I hope you can see that one off Let me see if I can just back that back out again and actually bring it in By hand See what that makes it any easier for you to see what's going on on there So what we're looking at now is this leg just yeah Yeah, we need to attach a 1k to this and then we need to put the transistor here Just for a little look see on that side So let's get this during them Ah, one case that's going to come off that leg. Yes, so I Could probably just nip that there and drop a bit of solder from there to there But I think I might extend it out just one And to keep things nice and trim just to make sure I've got plenty of space on the edge I'm actually gonna put that Put the resistor in like this Should I do it that way around or that way around that's gonna be further away from the transistor itself So you can go like that Which means then all I'm gonna do is go a little bit over up there And I don't have to get too close here because it can be a little bit Not problematic, but just you know things get in the way. Let me just find a better tool For just bending his head. We're just like a nice straight bend There and we go perfect that can be bent up there So I'm just gonna tack this down just oh and I Don't smoke I used to smoke I don't smoke And it was mentioned about the tin here or tobacco tins, but this It is not it's a vacuum tin. This is actually a calming collar for my pussy cats But do they work Calms me out 15 quid like so Yeah, I don't know where it works on To be honest with you as he calmed down not really anybody's a you know is a young captain Which to expect from young cats. He's calmed down a bit now. I mean he was Jumping off the top of the door frame of my wardrobe and stuff in the bedroom early hours I was doing my neighbors head in a little bit But why started doing was locking him out the bedroom. I Didn't know what else I could do. So I just thought what if I just lock him out the bedroom and Then at least He can't be in there to jump about the place Just turn that on to that right so there's There's our one key. That's just where we want that. That's nice And then we're gonna put a we got a capacitor to cross punk Rossier hundred puff and our Yeah, because we're gonna go into the base of that and that's gonna come down The base of this transistor now, let me make sure I get the right one. We want the one fifty thirty-five on here And this is the thirty-four There we go the one fifty thirty-five Now, let me just double check that my pussy does not right behind my legs as I move back because We've got to bring this down a little check and just see where the Letter things are on this. I did actually take this apart to see how easy it was gonna be And it's not terribly difficult. I just couldn't be bothered to do it at the time How easy it would be to put this into Green amber and red just swap these two over It's quite nice in there. I should show you inside. All right So the base is on one collectors on two and the emitter is on three. So base collector emitter All right, it's good to that We're gonna want The emitter side is going to be going to the positive rail and the base It's got to be coming behind us So I'm just gonna move that down like that. And then we got to get this Emitter base collector emitter, sorry Is that the way it said it was Base collector emitter. Yeah, that was right wasn't it? I'm gonna double check They look that's the thing about this doing these is to check check check again Especially you had a bit of a rough weekend Mine so a lot of people who wouldn't bother maybe base collector emitter. Yeah, so it is on three We want to make sure that the emitter is going to the positive rail and the collectors going to the to the 1k All right, so we've got a little bit of messing about to do here But it's not going to be terribly bad because if I just bend that down And just bend that like this I can then get that out the way and you remember it's me reverse now So base collector emitter just remember the meter goes to the positive and the collector is going to go off this way to the 1k resistor and this base is going to come back to the five 560 resistor So where can I put that into my that happened nicely? Probably just about there. I'm gonna give it a bit more space as we can There's just enough real estate really, you know when you're doing it as amateur issues this There's just enough real estate on there to do this and look at that. Look that works out lovely to there So I'll do Is I'll use one of these? Preformed If we can that's a bit long Just to try to keep you looking neat and tidy If we can and there's a makes it look quite nice putting something like this. I know I don't have to Don't have to at all I'm gonna see if we can I is just going to see if we can now that does fit there Little bit special I just bend that down a little bit. I'll just bend that down a little bit. I don't think I've got one That's any smaller Or maybe I have If that fit in there with that that'd be great But I'll tell you now that getting these like this Is not very good if it comes to making changes if you find you've made a mistake So I'd say get it right start off with Honestly, you're better off checking double checking triple checking And depending on how neat you want to make it look Depending how much you might want to fuff around doing things, but there you go. You see now we've connected our base here theoretically to the 560 resistor green five blue six zero zero So the 560 resistor So that's great. So we're just tack padding with a wee bit of solder and This coming across There is our 560 resistor so that wants to go this away I Don't know if in neatness now ever I'm gonna pull that up just pull that apart the way you can see that Why not stick me big head in the way? And I might just pull this up out the way Yeah, that's the 560 resistor and then put that down flat that away so That goes across the top of that. Let me show you what I mean There you go, so it just goes down over the top like that and do a little flat next it messes it up doesn't only Okay, so yes, we're gonna tap that down there and we have And this over this way because it's just easier This That's easier Lovely, and I'm gonna nip that off there. I'll nip this off there Might need it again Nip that off there Nip that off there And nip that off there beautiful Okay, it's the smallest bits now to solder We're gonna need another one or two of those That's so much as comfortable in a little box all my cats fell down the stairs All right, so there They're soldered in. Is that nice and level? Yeah So now we got the base collector emitter so we can put the emitter out to this side Just hold the transistor. So I don't want it to Move out of shape. I want it to stay nice and level and looking good And then this one here needs to come to this 1k Resistor again hold that in place. I just pull that down to the 1k resistor look at that look It is just the right length to be doing that and everything stayed looking Neat enough for me Neat enough for me. All right, so we're just gonna soldering and the actual Those leads there those are just just fit nicely to there That's good, but this will have a bit of heavier solder Which means I'm gonna be soldering not just the tab and be soldering A bit heavier like that. It's nice and thick there because we have a bit more current going through and as we get down the end The solder will get thicker As we're soldering right, okay, now we also need between this 1k and our base, I believe we need a 100p Capacitor so I'm just gonna put that here between there And there will be perfect. This wants to be Pretty short on the lead. There we go. Get that nicely tucked in down there Then on the other side We'll have that for our base. I'm sorry for our The 1k as we're going to the 1k there, aren't we? And I've just gone all the way on that so maybe actually just for To make that slightly, I may just go in here In the middle part there and solder it otherwise I've got to try and bridge it So let me show you what I mean So from here the way I've done it is even though it comes out okay But it comes out to this side and I really want to get into the middle part there That's seeable. I want to get into the middle part there just to make it easy Otherwise I've got to go left and then add angle. So I'm gonna put it straight here So I've only got to do one angle and get this out without too much Fafting I think then I still be there I hit the right place there just one more in Straight look there All right nice short leads again On this capacitor And this one just wants to go on to our base That's nice. And this I'm just gonna use this little stick just Just a neat and up that bend there Don't have to do it like this. I just do it because you know at the end of the day I'm gonna be looking at this afterwards and criticise myself Whether I could have done it neat or You know, it's just me Okay Okay, it's just a chin nose off always keeping in mind pussycats and feet Okay, right now. What's that there? So we've still got this I think this is the base of this I Know it's nice. The is a collector and we need to attach that between between our 1k and It's gonna go down to our mid on to our collector of this so So there's our one K what side of the one K do we want to be gonna get this right? So our base is coming off here, and that's connecting That's off this one what about this one? Yeah, so the emitter Is gonna be going off towards our the other side of this and that's there on this pot the the base itself is on The sweeper side of the pot, which is the middle on this And then on the other side of the pot there. We have our one K resistor and that goes onto the Collector of this transistor now We want to make sure that that one K resistor and our collector of this transistor a Connected Okay so the collector of this transistor needs to be connected to this one K resistor here on The transistor side so it needs to connect Yeah, as far as I can tell I hope that's correct You've got one coming off because that we just bridged down with that Call blimey you can sometimes look a little bit Because that one's coming off because everything's so tight and you see and then that's the base This is where we've made that connection from that middle To the one K resistor. So this is actually where we want to be then we want a connection between here and here Just double check that and that seems to be about right He says Poor blimey, I'm sort of spoofing myself here a little bit now Because that is the one K resistor right but for some reason It almost looks like what I've done. I think I've made a mistake I think I've made a mistake And this could be a big problem mistake if I have So what I'm going to try and do here is just try and figure out because that comes off here, you see Mmm To that but that seems to have got the one K resistor All all in one go This is why you're gonna be so so careful Well, I need to just check between these two joints. So what we are we will One with the edge one two three four five six in and six and seven here The edge one two three four five six and seven that looks like that's connected together So Nate said there should be one K between there and there Give me a multimeter These things you're better off checking now honestly And so it may seem like it's a pain, but when it comes down to doing this sort of thing You're much better off just keep it on top of it while you think there could be a problem check All right, so we've got one K resistance and there's nothing connecting between them This is what we want except they were connecting You know this so there is a gap there. That's good There is a gap it can get a bit confusing when you're looking at it like this Let's see all this solder across anything. Oh, I've made a mistake somewhere because everything's so close together So it's always just check double check triple check. It's It's a lot easier to correct things Like this or even just get it right in the first place and try to make a correction afterwards Okay, so where are we now? We're on this emitter Are there the collector of here? And we still want to come down to that side of the one the one K so we want to be on this side of the one K I was right all along But I prefer to spend my time checking and triple checking like I said rather than making a mistake And it cost me later And scratching my head and thinking I've got gonna go through the whole circuit Right so that there Will do That's how we're gonna pin that down literally just gonna use that piece of lead and bridge across there He says you watch this go all over the place. That's why I try and do Yeah, so let me just see if I can just warm this up just on the first Get a bit of soldering there Okay, doesn't matter. It's slightly bent at the moment I can pull that back through Like that a little bit warm on the finger when you do that as long as you remember then hold it on there forever Let's just tie it up there Just tag it down this side Yeah, take it down that's all in place there All right, so we got that. We're not quite on the Resist the yeah There is a small gap That's okay. Now we can get the rest of that now the rest of it's cooling down a bit I'll do it from this side here. There we go try not to leave any Sharpish-looking points sticking up So you could act as little antennas bring noise into your To your circuit and we don't want that So okay, so we've got that connected now to this 1k and That in turn is connected to the To the collector of this place. Yep core blimey. We're nearly there for a couple of Yeah, we've got 100 micro farad there. This is connected up now So just look at the look at the sheet look at the schematic We can see Just hang tight for a minute. Cheers down tight Okay, so we can have a little quick look on here might be easier to see on here So I should I get this thing doing the right thing? So basically now we are connected up to here So we've just connected this piece here with our little L-shape going down here So and this is connected here So now we need to bring something out from this 3.3k here and bring it in so we can get the first of the driver Transistors connected. Okay Let me see if I can put that somewhere where it can be remain visible until it turns itself off of course Because it will do that Helpful I can't see it from here properly because I'm looking through through the top of this thing here So I'm easier looking at the one on the on the left-hand side on the laptop alright BC 5 or 6 We've got this coming here going between these two in between those two three point 3k threes by three point three Karem Resistors so from this side of the resistor From this side here. We need to come down here and connect to the base of 155 so because of the amount of Space we've got Because after the main transistors there's some other gummings, but you remember I've got to connect the main transistors to a heat sink So that's gonna be sat here and I want the main transistor sat here So all the gummings that comes afterwards all the circuit comes afterwards. I've got to build it around the side Don't worry. I've done this before Right, so we've got that connecting to there and now from this We need it to get down there a little bit. So let's put in Let's put in one of these just This is the 35 yep So let's put this in and now we've got base collector emitter if I remember correctly Base collector emitter. Yeah, and so we're gonna want this to be this way round base coming backwards Bend that down gently So we don't force it too much because we break it. Yeah, we haven't got any spares I mean there is one for the other channel, but we don't want to be using it We want it for the other channel, which I will build Off camera, I think one channel is gonna be enough On camera Okay, so yeah, just get those legs like that so It's easy enough to sort of fit. Yep Remember we're gonna be coming through the middle here from this. So we want to be down down here somewhere Yeah, it's nice that we've got these grids makes life dead easy to see what's What's short and what's not but I've also got to remember what else I've got to get on there So I don't want it to be too Too far out so that I think that should be okay. I think if I run a one of these wires One of these now Well, then again, I'm gonna do it underneath to it's gonna be a lead of something lead of a nice But now let me just check to make sure I'm gonna be able to get this other stuff in We want a hundred puff between We're gonna have a resistor coming off this collector Going down to the negative side of our round. That's a 220k We'll pop that in now to to there's two reds and two blacks 220 and then we got the The kilo at the end of there It's nice. No, it looks like it's brown, but I think that's 220k anyway or 220 ohms. I should say All right 220 ohms, so I'm just gonna put that in from There to 220 ohms Tied it out up by putting that up a bit tighter To there and that wants to come out to there right and then And then we want a hundred puff between the base of this transistor and that 220 Say hundred puff instead of 100 pico So that can go directly to there and then we're going to do on the base there Again, just try and make sure we get it as short as possible But not to worry about it too much We can just use these to pull it through without nipping it across there to there I mean that should be okay pushing down any further. Don't look like I'm gonna be able to not unless I redo that like this Yeah, I want it as close as I can get it you see Close as you can get them to their needs and there we go if I just do a nice little Looks a bit messy like that Darn it. I don't want it to look messy Well, this is you know, you gotta have patience when it comes to these sort of things So I know not everybody's got patience. I watched a fella once kick the life out of a printer because he couldn't get it to work. I Never did understand it But we do understand that no one's got the patience There we go, so let's just pop that through like that. I'm happy enough with that. That'll do So it's fuffin about put that through like that. So we got those bends over that would do All right, then on the other side of This on the collector side We can just leave that for now It should we can just solder those in because we got a little bit of work to do With the power transistor, but problem being is it seems a bit Seems a bit more compact. I need the power transistors down here But we're not gonna worry about that just this minute. Let's just get this tapped in and just make sure we're in the right places doing the right things Okay, so this is our Base that's also got to come down to this here so This down Okay, bend in that down there That can stay short and that's actually got to move forward off here So just for now attack these down as first easier Now I Don't mean for these videos to go on as long as they do and I do really appreciate the time that you're giving me Watching them. So Nah, yeah, so that there We want to knit that off here And we can also just I don't see the point in keeping any of that is there there isn't really So let's just knit that off there Yeah, nice Nice blob on there It's in a little tiny bit that's sticking off It's gonna have that out Because we don't want that but we do want a line between here and here No Because that's going underneath here. I'm not gonna bother trying to fit The wire with it I'm just gonna take one of these Preferably a thick one we can and drop it down here And soldered that in just like that and then we'll put a heavier track on that Once we're done. Okay, so I'm just gonna tack this end first It's gonna have to be Really done And then tack this end here Beautiful It's gonna make this a little bit heavier here push that down Make it a little bit heavier onto this corner So I've got a bit more of a Get more of a nice tap on there And then of course I want to go Down here down here Connecting this to this that's uh A hundred puff that's okay. That's supposed to be connected. Just checking and we go and do this Down to this Okay Not that it really needs to be terribly heavy there. It's only the base Um, but still because we don't want it to flop into about in the wind All righty-ho. So we've got that connected to uh 220 That's going to be going directly to the negative 35 row That's good. This is for the negative 35 row That's good. So I just terminate those like that There's our hundred puff and now off this now. It's going to come the base I do believe Sorry, not the base. It's going to be the collector. We've got to get our 233 At least five watt Point 33 is in here Now this is quite critical this part I mean, it's all pretty critical, but uh, this part's quite critical. So we've got to get it either side We're running a wire remember from this 22k We're running a wire All the way down here. It's connected here with this Uh 100 micro farad And it's going to be coming down between the two 33s and as our out point As a positive out point, this is where the signal is going to be, you know Doing that's our positive output. So we've got to get this right We're going to get it all right, but we're definitely going to get this right So Let's have a look how we're going to do this because we need one part to be connected to this, um Base Um Mitter side this part and then we need this part connecting to the middle Yeah, and that's going to be for both sides doing that But we're just going to concentrate on this little bit here first or should we get this one in here? and come off this, um collector of the b And get our other driver Transistor, I think we should do actually we've only got one left. So it's got to be that No, let's have a look. So we want to come down onto the um Is that one? So we want to come down With this here a base collector emitter Um, we want to come down place me little I can't find my little stick stick So now we want to come down From our base And get onto the collector here And connect to that one k Then the positive side of the one k onto the collector of the the bd one five. We're using 150 on three five All right That's what we're going to get done there. And then we go another 220 putting this onto the positive Out there. So let's do that base collector emitter God, I hope it is Oh my life. Have I just done that wrong? Do you know I've just done that one wrong? I've just put that one in wrong I've done this one wrong. Did anybody else notice that? But he's definitely wrong. I've done it the old uh I've done it the um I've done it the uh The idiot's way Have I Did I did I I did Um, yes, I did. Oh, I'm sorry people. I've made a mistake Okay We need another tool now I've made a mistake I've made a mistake Oops oops oops let's just we'll check that it's I've definitely made a mistake I've been thinking about these I think and I've just made a mistake Our base is supposed to come down to here Um To here but that's not that's the collector Oh dearie dearie me That would have um proven to be a problem Good job it's spotted. No way Good job it's spotted now Oh Get that thing loaded first. Oh dearie dearie me. That was a silly sausage mistake to make Silly sausage I'm hoping double hoping just clear that way easy enough. We don't want to have this thing too hot remember This is a very sensitive these things All right See Let's see we'll put that up now. I think I can Oh, what a silly sausage That can cause all sorts of problems when you do things like that All sorts of problems But once again, it's better that it's noticed now Then uh Later on I just hope that that's wiggly wiggly enough. Yep I might have to get a bit more off there to get it wiggly wiggly enough just to pull it out and just um Just to change that Do do do do Keep pressing the wrong button. Can I just wiggle that about I can I can I can I can Right that's all I want to be able to do right um oh gosh All right, so let's just uh rethink this then Right base collector emitter Habbit you see so we want to get this one to go back All right, so it generally does it a bit easier now. It's warmer Um, we still need to have a little bit that goes downwards Into the hole. That's just straightening that out Cool. Blimey. Look at that All right, let's straighten that out boy, oh boy, right so What we're going to do then is we're going to come off the front For the emitter it also means that these are not quite in the prong place that they want to be So we want our base going into here It's a collector going onto here. So that's the middle one So what I'm going to do then is I'm going to see if I can move this down a bit that one out that way Yeah, that's going to be the way it goes. Yeah So if I move this out forward I've got to be so careful with these The last thing you want to do is snapping at the package. It's uh That's going to be uh because there's a minimum order to buy these All right, all right, we can do this we can do this so we've got our base is going to come down to this one And that's still going to be the same like that's still going to be going to the The collector that's going to be going on the collector So can we do it like this? I'm going to shove it through holes now That's going to go a little long. I can go that's still going to go for the collector So we don't want that going on to there That's going to have to go back one It's going awfully close to this. So what I'm going to do Is I'm going to bend this Like so I don't want this backing up onto the Onto the um, all right, and then I think we're going to be all right if we just twiddle in this A bit a bit a bit twiddling that about a bit It's not the perfect Solution But it's a solution And it's going to work for us All right It doesn't look particularly too ugly either If this just turn it round a bit to get this front one down. Okay All right, the main thing is that the legs are going to be In a place that we can get them soldered Right, so base. Yeah, we still want that hundred puff going to the base But this This wants to be on this side Of the resistor So right we can do that easily just by doing that That is not a problem. That is not a problem at all. We just pull that out there Maybe I should have got to do the copper coffee before I started this and make sure I was Probably still have my heads in this in order to get Be able to do this again. I've had to get my computer working again I'm sorry if it's blowing about in the wind camera I've had to get my computer going again and I'm not used to living without a computer Since Right, so Let's just double check it So I'm coming off the collector And we will be in a second for this resistor I could have probably allowed that to go Directly downwards for that. So I'm just going to straighten this up Just hopefully it's still going to be amenable It's all my poking and prodding around I'll just straighten that up a little tiny bit looks a bit ugly doesn't it but As long as it does the job right Because we want that to go on this here This here one here now I can go to the Yep Here's pure in here. Okay That will just sit in there quite nicely beautiful All right, that means I can bring the The collector Dovet you over to this Resistor where it wants to be That hundred puff is now in the right place What if I can do anything about that by just making it go in a bit a bit tighter and I can And we are still on track With the base coming straight down to this here Because the base of this is this first leg just like it is here the first leg Okay, right God, please be so Please be so And then and then this can be bent across to go on to Resistor there. So we'll just bend that across now just to Get it more happily sit you Resistor it's got a little tiny bridge to make the solder not a problem And before I do that, I just want this Capacitor just to go drop a bit closer to the board So get him up to me and says There you go, you see and then I can just drop this onto here A bit closer to the board beautiful and it's going to go on to the base there And we're going to use a bit of extra length that we got now just to Bend that into a right angle So we'll be able to do that. Let's get these flat on there. Just bend it to a right angle Perfect, and then I can solder up to that Excellent. We're on the right side of the old Resistor Goody goody. I'm just going to tack that there for now because it's Wable wobbling about all right, and then I'm just push that down Bit nicer like that. It's slightly off Level and I can now Connect this to this Also, I believe That needs to go Across to Where's my base there it is All right, so there's my base No, it's not that they collect us on There's my base And that wants to get down there and he just goes in and that's just underneath here That's one I don't know how I'm trying to see where it is It's just down there I cut it pretty close to the To the perf board, all right, so that should have got that nicely If it hasn't, I'm just gonna go to make sure it has Base is not actually Connecting right the base has connected now Good All right, so I can get that over to there That's going to be the fail point on this Just double-check collect her Double-check it on there Just going to get these two to connect here My name is decided to stop She's informed me she's got a whole bunch of Bathroom work going on next week What's the week after? So that should be fun That should be fun for me But then again, I've got some works to do around here myself. So I'll probably do it at the same time She's on her works done So everyone's got a Sore and the drill and everything on the guy and I've got some deliveries today so that could be it I've just heard in them So I'm talking about Right and so the the emitter Is going to be going out to one of these One of these So I'm going to put it in my throat. There was a bit of a gap between these two But I don't think it's going to actually matter too much before I just fold up there for now And then because it's going to be going on to this one here the emitter I just cut this a little tiny bit more off that because I've got to connect to the emitter So where are we? Yeah, so the The emitter here Is what we're connected to I know it looks a bit reversed around on here, but it's I'm worried about it and then the top side of this Going out Needs to connect to this middle part here before it goes out and it can it could just do it round about here And that won't really matter So yeah But now we've got to fit in the other transistor here Um, but I need that to be down here like because like I say I need that to be able to connect to the heat sink There's no point being here. I want me to get the heat sink onto it And I should be able to do it. I did it before on the other two So I should be able to do it. How long we got going on here one hour 28 on my life Oh my life. Um, right. I'm going to take a little pause here just for a moment and um Just try and figure out what's going to be going on down the stairs if it's going to get really noisy I'm going to pause it and come back Even easier just to leave it rolling Cut out bits As I go along later
