 YouTube. Now it's sort of come back a time to take a look at this power supply just because I was asked a couple of times if I actually got it working properly. I took a look over the old video which I was trying to power an LED and it was at sort of 9 volts I think and it was only drawing about 100 milliamps which I decided then there was probably the power supply fault but it turns out that it was probably that LED and I decided yesterday after seeing a comment left on my previous video about this power supply I decided to just get it back on here and take another look. Before I've spoken about an issue that it has with these connectors down here, we've got three nuts, there's not one on there because I can't find one to fit it at this minute in time but when it doesn't get a very good connection here you see the voltage on the front but it doesn't give you all the current, almost almost like it teases you with the power. It's going to be really well clamped here to get through to these terminals on here. So I decided yesterday to give it a go. To my surprise and to my thrill, changing over those 840s which I did when it first popped. I've actually fixed it. So this isn't a video about how I fixed this now. It's about that it was fixed and it's just been sat on the floor on the other side of the room waiting for me to have a bit more knowledge and come back to it. So right I'm going to connect it up and show you that it's working. I was going to stick out the LED. I figured it might as well just get straight to this thing. I just want to show you that I haven't put a screw back there in the middle. Remember I said before about C28 is up there. It looked like it had a capacitor but it had been cut out well. Because there was a link left to schematic I've got to see that these capacitors 37 there is not populated nor is that one. So I didn't know it but I'd actually lost. The popping side was actually apparently blasted away but you'd have thought that you'd have found or I would have found the component in the casing. But I understand that regardless of the laws of physics things can still vaporise on this planet. So yeah and there's absolutely no change apart from those IRF-84s. I didn't know at once that there were about these two the wrong way around but again schematic I hope. I'm just not sure about these in the right place and it did have a sort of a noise here but I got a current limiter system here and when I connected it up yesterday I put it on the current limiter and of course you know I turned it up and I started drawing power through this and the current limiter gets bright and bright and the whole thing shuts down. And it did this a couple of times and after the second time of doing it I plugged in just directly to the socket bank over there and that noise has gone. So anyway let me demonstrate it. So there we go. I just start turning it up. The fan kicks in. There's no noises such. Bulbs start to light. A bit of voltage. And I put it on to... I don't know if it's the best way to see that but I don't even see that. Some hands. No noises. Actually I think it's better than what it was before. Sorry if that's floating around. That's just because of the way this light's working there. It's... hint of blaring. So it works. You get just a little tiny bit and listen. That's all balanced in the middle of nowhere land. As soon as it goes to a volt, it's over. But I suppose it's drawing current now as well which is... Yeah, that's fixed. No problem. I'm quite chuffed. I'm really happy because this supply comes in quite handy especially for... playing around with my Slayer of Science coil which will be the next thing I'll probably load on to it and play around with it again. I didn't want to play around with this too much. See I didn't want to get a probe in there or anything. I've not got an isolation transformer that'll give me the protection that I need to play around in one of these with a scope. Especially as I don't even know what I'm doing 100% and there are lots of pitfalls. I've watched quite a few videos on that. Thanks to the knowledgeable guys out there on YouTube. So yeah, apart from getting that nut on there, I'll find one. This all works as it should. I'm really chuffed. So yeah, it's working. It's going back into service on my bench. I'm just quick so you can see the current unit in... Let's do it. Eight and a half volts. I'll just start taking that below. There you go. It's about five amps, isn't it? So I'm going to go above fifteen and five. Five and a half amps. Yay!
