 I'm just wondering if you can see, what I can see here, I can get 41 volts out of this at the minute we have 45.9 going in, if I turn that down it says we've got 51 going in, so I turn this up to 58 volts, let me start doing this, turn this up to 13 volts, I get 68 volts, hey there YouTube now I said I was going to do this little experiment with this DPS 5015 that I got in here and I did try to do it and I was using a 650 watt power supply but for some reason I couldn't get any more than 60 watts out of it, in the end I figured it was the power supply that might be faulty so I took apart this little supply that I made with the LCT 3780 whatever it is I'll correct that because I've probably said it wrong because I had this connected into it so I took that apart and I've connected this power supply into like a here so if I switch that off so there's no output then we've got a little power light and if I switch this off a little power light goes out okay and I also put in some outputs here which they're connected directly to the input of this switch this is a double pole double throw switch so I can have the two inputs going here and it's completely isolated when I switch up I've got now input to here but if I keep that off it just has the inputs to here okay uh yeah so we've got outputs to here sorry so I switch this on because it's a boost converter it has to um you can only have the minimum of what the input is which is which is basically 12 volts coming from this unit here you know this is an ATX power supply 500 watts so I thought to myself okay I'll use directly from the output here and come down to the power connections to my little my little circuit here let me use some more light it's my little circuit with my induct coil on now at the minute I've got this four turn coil on here which uses the least amount of current is that my four three oh I'm sorry it's my three yeah it's my three turn so this doesn't quite use the least amount of current but it doesn't use as much current as a two turn it certainly doesn't use as much current as a single turn and what I was going to do first was I was just going to connect it go right into this boost converter and you got to remember off the boost converter as well as this display um yeah sorry we're going to connect this up already to that so before I just get this wire and put that on there as you can see we've got oscillation it's pulling 150 milliamps it's actually all the input power down really very slightly I could just because there's a bit of a load there now it should be just under 12 volts I don't want to do that as I'm gonna just gently turn this up because this is a single turn part you can go all the way up to 85 volts so yeah just gently start turning that up okay so the reason why that's doing this because this lamps on I'm close to it so we've got a good oscillation over there you see I'm escape uh early these on and there's no breakout at this point so I'm just going to force that okay so there's just a little time we have a breakout so we've got 21 volts at 0.6 amps what's that going up the look happens to my display the display doesn't like that it's coming down but considerably on the display very upstarted oscillation is good it's trying to say now that's 30 volts out one point there's no way that's like 45 watts anyway so we'll just turn it up a slightly more I don't want to break it but look how much that sort of dims up pretty much nothing I'm going to turn that back down again now because obviously obviously that's not happy well that's okay it was just an experiment anyway I'll just connect that from there if I can just connect that I'm going to show you that the display still works and I should still be able to turn up this boost converter all the way to about 85 volts and we get that on the output there about 85 will now be on the output there I can show you that by fixing up my display right back there I'll just put it at an angle if you can see it if I just check these two plugs just check that in there and you can see down there 35.47 volts which is close enough to what it says there okay so I'm going to turn that back down again if I turn it all the way down I know that we've got basically what the input voltage is in the very slight boost but of course that's um that's not what we want to be using to power this we really want to be using this and so if I put it over here the nice thing about this unit is it's until you press the power button which is underneath here it doesn't come off now have a minute it looks like it's set to I think it says 18 volts I'm just gonna I'm just gonna set that just drop that all the way down to zero because I like starting off with it on zero okay back to the voltage oh sorry go back to there and now I can press on the voltage one again press here a couple of times like we start taking the voltage up it says here we can start taking the voltage up oh we're gonna turn it on first that's a good idea we start taking the voltage up so three four volts and we've got oscillation over there so we know we know we're working that's before anything breaking out I think for some reason we seem to be oh I see that's because I gotta turn up the input voltage I'm being a bit of a no let me just turn up that input voltage so let's give it a there you go 40 volts let me just start turning this up and we get past that 12 watt stage so we got oscillation over there uh little LEDs come on I don't know break out as yet we've got break out now so it should be able to get probably like 36 volts out of this before we go input and it's basically the same there that we got a oscillation that doesn't look too terrible got a break out LEDs working and now we've got a one amp nearly at 34 volts which has just gone up to 1.2 bit of a jump and we like it when things like that start happening but if I uh I'll press this button again I can't really turn it up any higher just because uh the input voltage needs to do up but I don't want to turn up the input voltage uh too high while it's unload because it will show a different voltage and then when I turn it down it could overvolt this and kill it maximum 60 volts this can go up too so if I put 58 and a half volts to that let's start turning them up again and break out there now we can get mini 70 watts mini 70 watts we have 40 volts 1.7 amps and 6.2 watts well that seems to be all I can actually get out of this uh like this but I'll be able to get more if I change this this is what's holding this back now that's why I've got a few coils because now if I want to draw more power and get this uh to give it more of a display I need to adjust that or I can put some capacitance on because there's no capacitance on this circuit at the moment uh now part of the reason why I wanted to do this was because the um the warranty the warranty from alie alie alie express for this is is run out I've not had it a month and it's already run out so basically if I kill it I'm on my own or if I kill it I'm on my own to the point where I still got a bit of time with PayPal because I paid I'm pretty sure with PayPal I like to pay with PayPal because you get a bit of an extended warranty and the reason why I say like that is because I think you get like 60 days or something but it can take up to 45 days to get to you which if you're a shop re-selling these things that's no good at all of course because it could be on the shelf for a month let's say um but if you're just an individual buying them that's okay but so as you can see here I mean it says there what we're drawing 69 watts and that probably tallys up to around about that as well let's say 45 times 1.5 is uh 45 plus that half for that would be another sort of 20 so 65 70 about 70 watts yeah for what I'm going to do now is looking at these numbers that's the maximum I can do with that input I'm going to put a capacitor on there and we're going to see what we can do with that annoyingly you have to keep pressing this set button whenever you want to change this it's can be a bit annoying it'd be nice if it just stays so you can just turn it up and down as you wish you know in case you get a bit of a panic on or something's happening that you don't want to happen so I'm going to now turn the output off on that and I'm going to add some capacitance to the circuit and we're going to see what the difference is between that and that so just bear with me just while I've just had that right so what we've got going on so what I've done is I'll put this 10 millifarad on just to see what it's like let's put some lights on the subject 10 millifarads and we're gonna still got the same 58.3 volts and no no this has changed so I'm going to turn the output on I'm going to do this set thing so we can turn it up so three volts or something either is oscillation at three volts four volts and the next one is going to be the break out and that this coil is about 25 volts there we go as expected let's just turn it as far as it will go oh summit just went pop or did make a little noise wouldn't be surprised if that's that past the summit just did a little pop I don't know if you could have heard that on the actual video I did and there's no real difference so we're doing exactly the same on the walk that's me again that's just about the way I was getting exactly the same over there just goes out the way exactly the same there 69.78 so it's like it's like a fire and 1.68 amps I love looking at this especially I don't know how close or how detailed that is that you can see but for me it's quite detailed I quite like the look of it anyway let's turn this back down again so we'll press this set button we'll press this press this and we can start winding it down so you don't want to just turn the power off because there's going to be a lot of energy in this coil and it's going to want to go somewhere so it's nice to turn it all down to settle it all down okay so our output now can turn that off that's all the same now what I'm going to do now is I'm going to change this coil up and I'm going to put a I'll put the two-turn coil in and although it probably looks terrible because it's just a piece of copper wire and there's some electrical tape around it to insulate it from each other and everything else I'm going to stick them hopefully that's connected nicely and not touching anything that it shouldn't be let's give it a go turn the output power on there bring them on out let's make these buttons all turn that up okay oscillation straight away a little look actually so four volts 3.99 this is there when we get the oscillation let's see what the breakout voltage is on 17 volts 19 volts okay so the breakout voltage is no let me just turn it down again 17 volts 19 volts 20 volts breakout okay turn it up we're on 1.6 amps and we're only on 30 volts this time we're drawing nearly one amp over here 57 volts still we're 50 watts we're 34 volts 36 volts right we're on 72 watts at 2.2 amps I can't go any higher on that we're at 2 amps nearly 80 watts over on the boost converter 73 there we can't really go up any higher so I'm going to turn it down all the way and I'm just going to change that capacitor and put this 0.27 buck on let's cross in and see what happens now with that smaller capacitor so we've got a breakout that's what we can see over there because the way I've got that set up four volts again see where we get our breakout 17 volts 18 volts 19 volts 20 volts there we go it's probably going to be absolutely no difference really oh let me just turn that down just for a second actually I just want to check some I want to see how warm that is now we're all right let's turn it back up again a bit past that 19 20 25 33 33 so that's 36 volts 73 watts I have to keep in mind as well the difference there isn't really that great deal but then for this you have to leave it going a little bit for it to start oscillating itself so you get more of a prettier pattern out of this but considering there's only four extra watts that's been taken off there it's not a great deal really I've really got two amps out of voltage it's a pity that you can't actually get the voltage to go up any higher this is being pulled down here to 40 volts but so anyway let's take this back down don't even see look I can't really turn up the input voltage anymore okay I had to think but it was only for about about a second or two and what I thought was actually what I'm going to put this on top because this is my little where we get some of this flying off so I'm just going to coil this slightly so it sits underneath I'll just do it like a pig stale slightly I just want that to sit on top that was a good possibility this circuit won't work now because it tends to do that it tends to sort of play up a little bit when I'm doing this sort of stuff so let's see we can get it oscillating to start off with okay so I just turn it up we've got five volts there we go we've got an oscillation that's good but it took four volts we've got that oscillation okay so we're not really going to get breakout as what we've seen before but what we will be able to do is the is your favorite slide let's just put that there for a second I didn't get it as we can see we can get the tube to light up which we can that's not very bright at all but then it's only doing one point in watts so I just pop that up there and position this in such a way I'm just going to try some sort of backstop that's all metal that's probably not a good idea for me to be using that so let me just put that there and just swap that out for that glass so we're going to put you know clip the components and push them so let's see we've got 10 volts 120 milliamp 1.2 watts which adds up quite well I see that just slightly that's why these blue buttons again so okay we've got the three watts coming off this now oh that's nice and bright it's just uh flipped up I suppose you've got a 24 volts by going into that and that says it's 30 watts 1.2 uh 1.2 amps so where's my so we get anything up here we do not a great deal and I suppose we're using some of that up in uh drops it down to 10 15 what 10 15 watts and I was just trying to see what it does over there on the power spine was it down 57 actually it says it actually goes up in voltage to 58 volts there that's 57 that's quite a bright LED uh strip lump there's a bigger than I thought it's four-foot thing that is that's using a 30 watt power so I'm quite sure how many watts in this these strip lumps would be anyway for lighting things up I've never seen that efficient really but let me just adjust this I suppose I could turn it up a little bit and just see what we can do that's 50 that's sort of 60 watts not that massively different two amps but look at the voltage staying up over there look I still got 57 oh it's going down a bit that's maybe as I'm getting closer it's uh no as I got closer to the actual coil maybe it does take a little bit of right six oh no it's gonna turn this down okay so that's 12 volts seven seven five four zero just turn that off a second and then out the way do something to put on the top for a little bit of break up over there this is a a soldering iron tip that I used the other day for cutting some gunk stuff in my quadcopter so let's turn that up see what we get a breakout on the top so I'm going to 10 volts 1.3 watts with 30 milliamps our volts we've got might have to induce the breakout okay so that says 50 volts 50 watts so let's just see okay we've induced the breakout and I also need to keep a check on temperature so I'm just gonna turn this down just while I do that check on temperature that will be all right just to give it a little bit of experiment to see how we're gonna see let it break out for itself so we're on 20 volts 21 volts okay so it's breaking out for itself around about 28 volts ah now up to 30 volts not 60 watts practically we're still on sort of 58 volts 1.1 1.1 amps the thing I go above that 30 volts we're down to 50 51 48 we're going up now we're just dropping on the other side we're down to 37 now so the maximum we're going to get out there yeah we've got 75 watts we've got two amps 37 volts you can see that kind of a piddly bit of breakout really power spike doesn't feel warm or there's no warm air coming out of it really hmm but that's 70 watts going through the little wires up there coming through to the switch and stuff probably might be getting warmer in here huh and I don't have any fans to expel air out the back either so let's just turn that down a bit because it's still 75 watts still quite a bit of energy okay so I've got to be able to try well I've got to be able to give this more power it seems um this unit here um it's seeming like as it's dropping it's because it's not getting enough power from this unit here which is interesting and it might also mean that the power supply that was used before which is a 650 watt power supply may not have issues as such I thought it was I thought it got issues because this is doing practically the same thing as what that one was so so I don't want to think about that now I need to have that little reefing I'll be back in a bit
