 Hey there YouTube, I just thought I'd show you what I've been doing with this LTC3780. I have put it into a little project box, as you can see. I have taken out the pots that were actually on the board, those square multi-term pots. Unfortunately I don't have any 500k multi-term pots or a 200k multi-term pot. All I had was two 500k single turns and a 250k single turn. But I will be swapping out the 250k with a 200k when it comes in. Yeah, I put a little voltage and amp meter on there. It's not the one I'm going to use but because I can't find the wires for the I've just put this in for now. It's the same size as one of these but it does have different power connections. So I can't just interchange it. But this is the higher resolution. I ended up chucking in a big old heatsink into this. One because it will make it very light and it didn't feel very nice with just this inside there. And giving it more heatsink can't really hurt it can it? And I used some thermal paste. It's got a heatsink on the back of this. It's got the aluminium heatsink on the back of this. But it's got two screws that go through and they sort of protrude out the other side. So in order for me to give a nice flat connection on this surface I've had to put it on it in such a way that the screws are just sat over the edge of the heatsink. And then I put some thermal paste in between it and used a load of capacitive gunk. This stuff that they put around capacitors on circuit boards. Because that will hold it down nice. I've used the same white plastic gunk. You can see that just underneath here. Down the edge to hold this in. And it is all held really nice. I'd give it a good old shake around. But I've got all these stuff wires and stuff attached so I don't really want to do that. I'll put a fan on the back to pull air away from here. It's quite good. I'll put a couple of diodes on the out to put one. Because it says you want a diode anywhere if you're going to be charging batteries. And I just put a couple of 6 amp diodes there to pull down the voltage as well. I don't need. I'll be fine with 26 and a half volts. For some reason my switch doesn't work. It seems to be in a closed position no matter where I put it. So I need to take that out and put a switch and at the minute I just had to stick the green and black wire together. So the power would come on of course. And this wire here is for the LED. The green LED. So the green LED doesn't work at the moment. The power LED works. But the green, to say that we're switched on, standby top LED doesn't work. That's a standby, isn't it? To say that we're switched on doesn't work. Because I need the switch. I put a fan. This is a 12 volt brushless fan. Because it's small it does make a bit of noise. I put a 100 amp resistor in line with that. Just to slow it down a bit. Just so it's not as noisy but it's going to be beneficial to be there I'm sure from time to time. So even though this isn't all put together just yet. You can sort of get the general gist of what I'm doing. This box, this unit, once it's got it's lid on it's going to look quite neat and compact. It's going to look something like that. And it's going to have this shrouding over the wires between here and here. So it's going to be sort of like 10 inches of move. Flexibility between this unit and this unit. Which leaves it, you know, some choices for me to have to locate this. Like it's on top of this. I can have this, you know, at the back somewhere and have this. So you can see it. I did think I'd try and shove it over there somewhere. The power supply. The ATX box and have the supply maybe down here. But that's all for just trying to get it finished off. I just thought I'd show you this file because chances are, you know, I tried to make this video a few times and it kept messing up because this camera has been playing me up. There's a few you might have noticed over the last few videos of what it played up on me. I've done some experimenting with it. And I'm trying to get it so it doesn't keep playing up. So it'd be quite interesting to see if this video works out. But this is, I think this is the seventh time trying to record this. And I've missed bits out all along because when I was first putting this together, I was recording it and finding out that it wasn't actually recording, which is quite annoying. So I'm actually at the stage now where I'm thinking, well, you know, I'm going to be showing you the box finished very soon. I'm just going, I did it. So for the, you know, the ATX supply, I did all the regular stuff. I stuck a dummy load in between the highest amperage rails, which on this one is the five volt negative. So there is, I could do it again. I used 322 ohms because I didn't have any five ohm or 10 ohm resistors. But I've got a few 22 ohms, so I've got three together. I should be doing about 7.3 ohms at five watts. So that's plenty. There, that should be okay. I'm not going to use these 3.3. I'm not using the 12 volt negative. I'm not using these five volts or a couple of these negatives or these 12 volts. But I decided not to cut it all the way back because I may want to use them at some stage in the future for something. So I'll tape those up and just isolate them away from each other and just leave them in there, they'll be fine. And it will just be this nice tidy black shrouding coming out the back here and coming into the back here. I'll let it come partway through here and then I'll put some nice big clamping cable ties on there so they can't be pulled around. But it gives me some flexibility. Yeah, I'm just going to, I'm going to power it up. Just so you can see it working. I might have to just push it down a second. Push it down there. This is of course live, so I'd say to anybody playing around with this I'll be very, very careful. This will kill you. Or it can kill me. It's not necessarily that it will, but it can. Put your hands in that high voltage side. Ah. I've got a few at the front of that yet. So I can just switch this on. Okay, sounds quite enough doesn't it? And that fans great when there's, it gets quite noisy when there's, when there's no resistor there, but it's okay when there is. So that's the reason I said zero is because the, it's because there's a load, I'd say 0.3. If it wasn't for this, I've got this 12 volt bulb here just for demonstration just to show that it's, it all works. I tend to talk about three volts and then just leave it to catch up with itself. Because look at this, like 2.2. And as that warms up, as that bulbs all went up the element, it's dropping down. The filament I should save the element. There's, there's the bulb. I'd switch this light off. Let's see. Turn this up. We can definitely, definitely pull some power through here. That's the sort of maximum, sort of four and a half. You can just back that down because I know that the wires between here and here won't be too, won't be too keen on, on that. Yeah. And it'll be even nicer when that green LED works. I'll be a lot happier when the green LED works. And just isolate that away from the mains. So that's it. That's, that's all I've done so far. And I shall, once I've got it all connected up and in place and this bulb and everything and the switch on I'll probably do another couple of minutes follow up. But for now, that's as far as I've got with it. So anyway, cheers for watching guys, if you've got this far and yeah, I'll catch you on the next one.
