 Okay, so what I just did then, I just, I just bared the wires going into here and I've connected them to here So this is honest, but you're actually going to get the first view of this to see if it actually does work I've not changed the resistors. I'm just going to see if it works on a nearly 13 volts there. I don't know if you can see the front of that I've got my really wary hands on because it's playing around with some light voltage. Right, so okay, we should be ready to go. So if I flip this on, we've got 12.8 volts coming out of there, if I switch this on and it's definitely lighting up there. It does seem happy enough. Now it'll be interesting to see if we're going to square wave out, because to be fair, before when I've done this and I've ran it on, oh look, we've dropped down to just in 12 volts and when I've run it on 12 volts before, it's not giving me a square wave. Now I suppose this is because I've really got 12 volts rectified going in there and I'm trying to get 15 volts DC out of 12 volt AC transformer. So I'm going to hook this up to my little toy up there and see what comes out of this. So just give me a tick. Yeah, you see I just connected this up and because of the low voltage I'll show you. I'll connect it up there and because of the low voltage voltage pressed away from now, there's my triangle, there's my ramp, step, sine wave, square wave, nothing. This is because this has no voltage for the square wave and it needs 15 volts. So I've got to try and get this a little hung. It's giving me 15 volts and it's not doing it. So I have to go in there and play with the resistors and see what I can get out of it. So I'll have to come back and try this again in a little while when I've played with the resistors and maybe tomorrow because I've got to go to bed, I've got to go do some work in the morning. Okay, let's try again with a little bit of soldering all that I do is put these in, but it's actually looking in the right sort of direction, that would probably be helpful. Right, positive, positive, negative. I know I've got these ass back plugs, but that's all right, don't worry. I'm just going to check the voltage and see what's actually coming out of it. So let's give it a bit of AC again. Let's put some AC there. And I've not connected up this thing, I've just connected up the supply. Right, hang on, 15 volts, 15.1 and slightly climbing. I think that might just do it, because that hasn't got a load on it, so that'll probably pull it down to about 14 and a bit. So I reckon that might be quite safe just to hook that up, so I'm just going to manage by this to press first. Let's just turn this one off, turn that one off. I stuck a four centimeter in one. I kept me, I've got a 140 in there, going from the output to the common, and then from the common to the negative of the little electrolytic. I've got a 470m, just to take that, bring the power up a little time bit. And it seems to have done it. So and there should be enough, there should be enough juice in there, enough current juice in it, and just let this thing work once it's connected up. So let's give that a go then. Let's, all the boys are just trying to do one. So let's just grab all of this and connect this to the there here. A part of me's like, oh wouldn't that have been great if it had a blown up, you know, just for that side of it, because I'm having the capacitors on that block, that was quite good fun. And I'm telling you, when this thing, blue, where's it gone? This, uh, the tyronizer thing, when that blue, my ears rang for about a good five, 10 minutes afterwards, it was like hell of a bang, blew the, blew the side, clear out, pull off across the room. I had no idea what to do. I was just, I was just getting my heat gun down. I must have just clipped it. Anyway, let's see what we've got right up. And I hope this goes straight to the, straight to the scope as well, because it's that square wave is the one. It seems to be, it seems to want the extra bit of juice, or the right amount of juice. I should say not extra, I don't want any extra, just want some right amount, which is 15 volts. Let's just clip that to there, put that onto there. Yeah, there we go. So right by right, so we should be set for hitting that, oh God, that's dropped it down, but it is on. And we have still not got a square wave. He's pulling it down too much. Still no square wave up there. And that's what we need. We've got the other wave forms. We don't get the, we don't get the square wave. And we need the square wave. Ah, so I need to find me a bit more juice, because that's what I need. When it's on now, what did it pull it down to before? It pulled it down to, it was a little bit lighter, wasn't it? Okay, okay. Oh, I just need to kill, carry on playing around with the, carry on playing around with the resistors. And let's see what we can do with that. So it needs to be back, back in a minute. Okay, right. Oh, you can't see that, can you? What's going on? Oh, let me see. Oh, there we go. There we go. Right, 16 and a half volts. Just about. And we have a square wave. And we have a square wave. Don't know why I put it onto that supply. It didn't have a square wave. I switched it on a few times really quickly. And the square wave came back. So I prepped it around here. I put a couple of resistors together. I don't actually know what the value of that is now. Let me over look what this is and I'll tell you what the volume. Oh, that's the 820. So that's got to be the 560 and and the 480 or something. Oh, you can't see that. Regardless, it works. I put a heatsink on here because that was getting a little bit warmer with a little bit of thermal paste. Then we have a square wave 5 watt peak to peak, 22 hertz. And it's up there. Of course, it will never change the way it fall. Lovely, lovely, a bit of a user. Oh, that's the sound and the square. Lovely, ready, chubbly. So, I suppose there's still a question remains. Is that okay to do that like that? Yeah, because that's all I've got. We've got a little four wave rectifier there, even though it's only two diodes. We'll use those two diodes. These two capacitors allow me to double the voltage on the power supply. So I get 20, well, basically because it's DC then, after it's been rectified through those two. I get 34 volts. 12 volt rectifier, dropping the resistors in between the output and the ground. Sorry, not the output on the ground. The common on the ground allows me to play with the voltage coming out of the regulator. And so I've got it out. Well, it's just in the 17 volts. Let me turn this off. There you go. I was going to say it's round about 17 volts. And that's basically what I got when I turn off the, when I turn that off. And this is what happens when I turn this on sometimes. It's got that. If I just switch it like that, it's not always done there. It's probably something to do with this supply, some arm doing. I'm pretty convinced of it. But I'm not sure, of course, every time that it's coming back on with square wave, it doesn't have any issues there anymore. It's not the cutest looking square waves, but I have got this monitor up here that, you know, this light is a fluorescent, as you can see that it's fluorescent to magnifying the last light. So it doesn't actually make any difference to it whatsoever. The voltage is relatively stable. It's sort of flicking around there. I don't know. I've not really been watching it, but it does seem sort of stable. It should be all right, maybe. And this is, that's not really warm. Now I'll put the heatsink on. The rectifier was getting a little bit warm. I'll put a heatsink on there. I'm so a bit of film pasting. Yeah, that's all right. It's sort of, if you look at the, I'll give that a little bit of a, but I'm sure that's going to be done, so I'm pushing it in now quite hard. I suppose that's going to be something down to the, the holes, the sockets on them, then resistance monitor. So pretty happy that's working. Right, that's what I just wanted to show. Basically it was having a little bit of an issue, wasn't it, when I was turning it on and off. I'll use this switch just here for the, just to turn it off, let it load again. And, you know, we've still got a square wave up there. That's not a problem. Sorry about my shape, your hand, I'm leading on there. So I'm here. And if I turn it on and off from here as well, I'll turn it back on. It seems that I changed the capacitors. I put a 2200 mic niche on there, and there are 220 mic sanyos, and that's a 2002 and again sanyo there. And that seems to have stopped it from being a bit weird at the start, and I've still got my, still got my square wave. Only the waveforms, even though that looks a bit mental. I think I've a lot of, a lot of experience and it's not my light, but that is on a 180, oh, not sure if it actually goes up that high, 180,200k. Yeah, yeah, it's supposed to go up to 200,000. Okay, I'll just set that down there. See, I'll just take that down all that. I don't want to do all that, just go to the frequency, and if I go to like 50, oops, it's a bit sensitive, and then wow, you push this thing up. I just adjust that. That's a bit better. So I mean, this isn't the greatest of supply, and I don't think that the actual battery, the, I don't think that's very much cup at all. I think that's probably a bag of rubbish, like say, come up one of those really cheap lights, one of those really cheap halogen like desk lamps, that if you touch the two metal telescopic things going up, I know I did it with a metal thing, but I looked at a couple of EBO videos, and instead of you do that, kind of what they said happens, but it's not a very good thing to do anyway. So you could be something to do that. What I'm going to do in a minute is I'm just going to try all this again on my supply over there, and see if I've still got the same sort of light, you know, that weird sort of issue going on when it was at the higher frequency. But yeah, so it switches on nicely now, and I'll be getting the square wave. So I'm quite chuffed with that, and if I do work out that it just wants to do the supply, I might have to swap this out with something else and just make it so it's a little bit cleaner there. Anyhow, fellas, guys, girls, if you got this far, thank you very much for giving me your time, and if anyone can tell me if this will be an issue, that is hot. That is quite warm, so I probably will have to put a bigger heat sink down there, because that's too warm to keep my finger on to be fair. Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah. It's too warm to keep my finger on. So maybe I really do need to rethink about the entire supply on this. I've got a 15 volt war, I don't know why I didn't bother just putting that in there, but I wanted to play around and build the engine, just to experiment, so you give me something to do. So anyway, I can say thank you very much if you got this far. Cheers, guys. Just to let you know, just for a tick, but I've just tried it, I've got a connector on over there, 15 volts, right amount, you know, it's doing everything it should do, but I still get this, oh, I still get this. It's when I go through the, it's still got this, it's still got this thing going on, which isn't very good. If I turn my light off, it doesn't really make a difference. So that's at 180 kilohertz. I'm not sure, you know, this thing's happy to go through all that. This time where it works, okay. There we go. Just to let you know, it looks like it's not actually the power supply issue, because it's actually going to be my decent supply over there. So, yeah.
