 So the 500W power supply didn't really put out the amount of power that I thought it was going to. You know I figured if the other one was faulty then maybe this one would, it was more than 70W. I know that circuit draws more than 70W. I know I should be able to get that on at least, you know, around about the 5A at 30V. And that's more than 70W. So what I'm going to do now is I've got these power supplies, these old switch mode power supplies from old Xboxes. And so I'm going to try one of these, I'm going to take this apart again, do the necessary modifications to leave, you know, the bits and pieces I've got attached to this in here. But I'm going to do it in order to I can just chuck and change power supplies. I think this is going to have to be like, it's going to have to be like what this one used to be. Where it was continuously taking out the transformer, the other stuff, I'd put it in there and then take it back out. And so it never actually got to be, just sit there being ready to be used. So this one's going to be like that for a little while because I'm going to try again with this coil. And I did make a video and I also showed that when I just used an element on this, I still couldn't get out very much power even from this. I think I managed to get it up to, it wasn't a lot. It was around about the same amount, it was about 30, 40, it wasn't a lot. I'll have to go over the video, I'll put the video up. But it wasn't a great deal even using a load, like a heating element load, straight onto the terminals here and turn it up full whack and it still wasn't hardly doing anything. So it's got to be the source unless, I can't remember when I did the test on this. I can't remember how much current it was drawing, but it was drawing a bit of power. And then if that doesn't work very well, if using one of these ATX, it doesn't work very well. Okay, I didn't actually realise how easy I'd made it on myself. All I had to do was just cut these power wires and cut the cable tie holding the wires in the back and the rest of it was just in the chuck block. Not this one, I left it on the ATX supply so I can just plug these wires back into it, reconnect these wires and we're good to go again. Like that, so just ignore this stuff here. So we've got this switch mode is on now, we've got 12 volts as it's minimum, not to turn down as far as I can turn this down, but as I can turn that up, 85.5, a little bit more, 86.6. So of course the maximum we can put into this still is 60 volts, I believe. Let's not get that wrong, eh? And now I'm going to find something to stick on here first and see how much current we can draw at what voltage using my heating element. So here's the heating element, should move some of this stuff. I'm just going to do it quick. Just check on the, I went round too far, nearly on there. I should have already needed to have clicked it once. And really I've got underpastons, I don't want underpastons, I want them on resistance. Being a bit of a goobhead. Oh that's just clicked on there, just clicked this on there. I think that's 50, is it 50 ohms? There we go, we've got 52.84. And then between here and here, should be about half of that. Oh double it, okay so the smallest one we've got is 50 ohms. Oh we've got 100 ohms, that's a big resistance, right? So I'm going to, I've got these here, I've got one over there, that's a nice piece. Okay so I've started to resort to this camera because the other one's getting mental again. So what I've done is I've connected directly to my battery there, this yellow is negative and the red is positive. And it's just connected to that junction box there where it says fuse. It's just connected to the crocodile clips of this actually which goes into my battery charger for my quad. So we've got those wires that come in here, they're just coming into here, not a biggie. And I've got this 50 ohm load on there which is quite happily to do. It's a mains, it's a heater element, so let's just flick this on as I don't know whether it recorded last time. So we just turn it all the way up and again we're staying around about the same voltage, around about the same amperage but we could definitely pull more through the battery system. So it is, it does seem to be limited from on here. So that's under the minimal voltage and I did this already a couple of times, did the just the twiddle of the amp in here in case there's any sort of restriction. But I'm telling you now I've stripped both the ones that I've got of these and it's not even connected to the board. I mean it's in there, it's got holes and it's been put in there but there's no tracks that lead into the rest of the circuit with this. So I didn't expect it to do anything and if it did I would be very, very surprised but just because it's using my batteries I'll just put it back on again. But it's not doing anything so the restriction may not be then with my power supplies like this one here that I've just tried and the other two ATXs. It could be down to this, it could be down to that, not actually putting out the power. Huh. Now I know one of them and I did a video where we were pulling out quite a bit of power from it. But do you know I can't even remember how I was powering that in the first place. It must have been from the other power supply. But that's worth sort of taking into account because I've been trying to, trying to do something with this you know because the, oh what's that then? Oh it's just this bit of plastic I've left on there. Oh it's not, it's actually this plastic, this one's coming off it, sticky and gunky. Anyway, yeah so it's this. It's the boost converter isn't allowing enough power in. Oh I forgot I've got that powered on there. Like just through to the switch I could have powered it directly from here from this wire I suppose. But you know I'd expect to see a lot more going through there and for these they're quite warm and messed up. Start smelling if that was actually drawing that amount of current through it. Right I need to investigate this a little bit more and see what I can do about it. Well I could have been hitting all this on the wrong angle. I'll tell you for why. Because at the minute there's 40 volts on the output here. Let's say for the other camera keeps playing up so I'm going to have to just use this one. Okay it says minus 40 that's just because I've got the wires on the way around. You see that 40 volts and I've got it just connected to this power supply. So now I reconnect this back up to there. Switch this back to the 10 amp mains. For some reason mine is not reading in amps. Maybe I've blown up without knowing. And now this is where this all fails isn't it. So I'm going to hold this and do them both my hands. Where's that little hand moved holder? Well we're going to have to make do without me being a holder on 20 things. So here's what these things are there for. So we've got that on to there. 0.72 and that's sort of 40 volts right? Last round about what it was doing. Anyways we ain't got a problem with that. Now what I want to do is have a different load. And this is where this is a 10 ohm load. I'm going to connect this to there. Now I'm expecting to see a big ampage jump. So let's have a little look. Can you see that formula? It's probably not the greatest. Let's see if we can get that so it's going to be a better angle. And now I'm going to, oh did you see the little? Actually that's starting to smoke already. But that's because at 40 volts it was drawn about 3.5 amps. So I'll just do it once looking over there. Yeah 3.48 so let's say 3.5 got smoke coming off that now. So I'll let that cool down. So 40 times 3 is 120 plus half of that. So it's not 130 watts. Oh sorry 140 watts. So it's delivering, but do you hear the noise it makes? But there is 140 watts there that can be delivered. So I've been looking at this all wrong. And other than that I'm going through some stuff. And I've not been thinking that clearly on what I've been doing. But I'm curious because before I've drawn a lot more current through that coil it must be this one's doing a setup now. But I was hoping that was going to deliver the power to thing. Now remember this is only 12 volts going into this. So I think I actually need to put the power up going in in order to have more power to use, you know, like that 600 watts that it's claimed that this can put out. And I think that's where I'm in wrong because what I'm doing is I'm putting my battery power into here, not at the minute using this. But when it's in here or when this one is wired up, I have the battery power going into this and then from this to this. I think I have to be able to deliver more power into that sometimes. Or now what I should and I should have used this bloody load before shouldn't I? So now what I've got to do now is reset this back up again. We're trying to be five minutes. Reset that back up again and try this load, this 10 ohm load. This one certainly does get it to draw a bit of power. This one as you can hear it, it draws the power off this. But it does make that noise through the inductor. It's press on to. I'm not going to do it with my finger. I'm going to do it back down here again so you can see the 3.4 line. But look, as you can see it's smoked. You can see it's smoked. I'm more worried about these wires there. They don't seem to be holding up too low to put this. This does smoke a little bit. OK, I need to have another little rethink about how I'm going to try and pour more power through that coil using this setup. Because it can obviously do it and the boost converter is all right at 12 volts. Maybe I should try the other power supply on this and see if the other power supply is giving out enough power. Yeah, that's going to be in the next lot. I'm not going to do it tonight though, I don't think. I may do, but I'll see.
