 Hey guys All right after I've been lots of lots of problems with this. I don't think it's the actual Supply itself. It was me what I'd been doing with it. I think I was asking a little bit too much of it and my desoldering skills still Developing So I've decided I'm not going to turn around with this because they keep blowing this D8 8-2 and It's doing a hidden so I Another one there'll be some space on that one I'll reorder this one, so I'll rebuild it now and And we'll see where we go from there So what we got rectified lodes a whole bunch resistors TL 08 one CP These little like up and things is a few of those Got our main transistor Voltage regulator, so it's a nice input Just there. I think this is where I see That's a bit of a load on it. I'm not quite sure Well, yeah, you get the YSE you don't have to actually put these solder these to the board You can use these connectors. I'm going to use one of these and I've got a 1010 pop I'm gonna use for the Voltage control and then just use one of these 10ks for The adjust on the current it'll heat sink Yeah some transistors Okay, bunch of pastors all the things that you need to build this up. Now the nice thing about this Is that you can see everything's written on the board, so If you can't read the You can't read them resistors. Let me have a look see if they're written under these little bits. I think they're going to be You can't read this. I think this is 220. They're a little look on my Things he won't get any better at this No, it's 2.2. So if you like me, you're not very good at reading the resistors, so I'll Make sure you've got a meter handy because that's going to be the only part I think 10 for Which is a hundred nanofarads, so quick little check on that Okay, so I'm gonna If I remember rightly when I first built this there was absolutely nothing Nothing sort of noteworthy. I suppose when you put the heatsink on for The D882 connect the heatsink to the transistor first Because the heatsink's got a couple of little pins on it But go into these holes really if you set that in there then just like You know tack those in At least you know that your transistor will fit as it should and get it the right way around as well Right, I'm gonna fast forward through the next bit Make it look nice like it's had some Time and not just been rushed so that's the 24 volt Voltage regulator because it comes in as 24 volts on the AC But then because we regulated DC. We've got a times up 24 by 1.4 1.4 1 4 That should give us about 36 volts DC Okay, so we just want the little connection for the fan It's going to 24 volt fan It's not a tight squeeze, but it's gonna be a snug squeeze And what the difference is snug and tight Snug and once tight Now this is where it gets a little bit because that's just fallen out on the holes now It's full of Solder so I'm gonna see if I can just quit you cheat this by putting one in And see what you just want to solve on the other side and see the leg will just go through I've got a funny thing this is gonna be a pain now. No, just just managed to do that a Little bit of a look on our side Okay, wasn't there punch for that mistake. Okay So there's just that Just this transistor Oh, and this head is what's the hitters for? I don't know where they go Unless this is out something else not even for this. Yeah, I'll read up them Okay, so just go sort of those And find somewhere so it's gonna get somewhere. Okay got some wire Okay, I'm gonna put all this on to the And the long bits now. I'm just gonna speed this bit up Okay, right Well, I forgot to press the metal record. So I've put this on and agree. So we've got the D10 47 and is the volume control Voltage, I mean Here's the one Not the most tiny thing of soldering there, but never mind I've not used these ones yet. These are from the these are from the the other kid They don't want it done work Well, it does but it just keeps blowing this So I think that should be okay to go now there is a slot there for a 24 volt fan Extract a fan off There we go and this Is what we're gonna use to give it some power now what we got here is a Well, it's 24 volts AC and this is getting to the mains and then by once should be able to feed this into here lovely chameleon and Just for testing purposes this won't So on state lines, of course, I'm gonna get a better get a case and decide This particular power supply too big or not And I also need to do inrush filtering I was wondering I don't know if it's if I can basically bang one of these capacitors I've actually got one with some heat shrink, but I suppose I could put some heat shrink on it and bang this across the Inlet here Just to give that a little bit of a Little bit of protection I'm not quite sure what to do there because on the mouth type of things because I don't have an earth connection on this So yeah, I think that's what I'm gonna do But I just thought I'd just power it on and just put it on power it up And see if it actually gets my life out of it. That'd be terrible. I've got a case of these as a present friend Right, so what do we want? We want to plug this in and plug this in One of the screw door. We don't need someone anymore. Oh, we want to We want to see some voltage coming out, don't they? Now I am not going to Connect a bulb A very nice car bulb, you know 12 volts 50 60 65 watts, I think it is But I'm a bit scared if I put that on it's just gonna make this thing go bang. Well, yeah, basically pop Because that's what keeps happening if I do it on the other Supply I can get it all working. I can see if I've got variable voltage and everything like turning the voltage control up and down and Then I can put something on that requires more than a couple of the amps And Bob, it just blows the Blues this up. That's not very good. I Don't suppose it matters which way this goes in the AC Pluratized is it? Okay Yeah Not put that down just yet those otherwise it's from the 24 volts coming off and These two are so yeah, these two so I can have it over 110 or I've got it in serial the primary for 240 There's no metal in here There's clear This one for a negative side it does say that this is the engineers dream or something because you can't kill it apparently Seven times that's nice. So you put one for that in DC Give it a fighting chance. Should we? Okay, I'm gonna I'm gonna turn the Current all the way down to zero. I'm gonna turn the volume control The volume control there's the voltage control all the way down to zero Just check on them the right ones. Yeah, none of these wires are touching so that does look a bit dodgy that connection That probably he hopes Okay, right. Let's supply some power fingers crossed people Okay, so we got A little bit does it do anything because the connection here seems to be Okay, so we do have a nice bit of control down to zero point one and if I turn this Amp all the way down that doesn't really make any difference. I start turning it up should get well, I would have thought that the I would have thought that the The LED would have come on. There's no load So I need to put a load on here. Then I let's put a little fan on just to start off Now this fan has got its own Regulates from here a little buck converter. So we can't do any you can't go any higher than 12 volts for the fan. So I just shove that in there And just put that in there. Hopefully not make a good enough connection that this will work Okay, right current limits. Come on. That's good. You can't see that can We can see the fans actually on Two of us if I give it Well, it doesn't matter what I take it up to because that's that's been pre-set up 12 volts So that's good Current limit on Okay It's still on You should be able to see that little Oh, you can see that turn that off. It's actually red here right to do you look you see the current limit light coming on It does look red here. So there we go Of course a bit like the test should be And if I can put And I do like having a 10 pot 10 turn pot Because you do get a lot better control life. I want to go on to 10 volts now Oh, it's just a control 10 volts to There we go So it's nice to have a little bit of control With that 10 pot turn 10 pot turn 10 turn pop Okay, so far so good. So I'm gonna get a bit of thumbs up So that was a nice quick easy build simple as it come It all works, which is nice. I shall do some more testing in a bit
