 there you do okay I'm just like playing around I've been on some parts as I blew up my power supply and I've just been prattling around with my auto transformer at the back I've got my auto transformer there and underneath it you can see that white donut that's my isolation transformer between that and the auto transformer is like three rubber discs last yeah rubber discs they're isolators you know for the transformers so I've just got that between there and there anyway let me make sure I got a nice pretty firm thing on there there I've got it connected into my connector block and somebody asked me so if you watch this CCNC CPC hold on yeah it's CPC they're like far now so what I've got here down the bottom there's a got a transformer it's a 240 volt in well it's two 110's so they're connected together you can see this purple and white wire down there that just makes the makes that 240 here instead of two 120's put some in series and then I've got the two outputs of 24 volts per channel two secondary windings on the output sorry 24 volts each so I've put them in series together to give me you know 48 and that's what I've got going into here so basically I've got like you know sort of 50 48 volts which I can adjust with this variable transformer which is brilliant and then it comes out to a bridge rectifier and at the minute this this is connected and this is a 50 amp thing it doesn't need to be on there anymore I was just checking it make sure it worked and that's just connected that multi-meter that was connected in and I'll put this back in and I think this is 10 amps or something there's plenty anyway absolutely plenty and they'll just get in there and get screwed in I'll do that in a minute get that set back up I should just not bother recording this because who's gonna want to watch me struggling I'm trying to put the wires in but I will screw them back together again and then that goes through that bridge rectifier which is coming out here to this capacitor just a few capacitors now they're a bit crap these capacitors to be further bit old and that's a 200 volt that's a hundred volt that's a hundred volt between them I think they make up to around about what we got with 820 there 820 there and I'll see this being that big but it's not a great deal it doesn't even make a like 470 micro farad 4700 sorry so it's not so it's not it's not a great and I've been putting these on because what I've been doing is I've been playing around with this little power supply circuit now so it's 96 and 317 but it's the LM 317 a HV which means this thing is like a 60 Volta which is quite good and I've got a tip 35 tip 30 55 35 from the back as a pass transistor current so now I did have my meter sort of like connected up to this but I decided to put these little things on instead because I just kept worrying that I was gonna waste the battery in there so I just thought I might as well connect these up now was the problem that I got is if I'm gonna go above 30 volts the input voltage for this to work on this one here is it says maximum 30 volts but I've put a resistor in line here with this one and I've also got a resistor in line here with this one because this is what just illuminates these are the power wires that just illuminate the and the working voltage for it but it's the maximum I'm pretty sure I've had it up to 44 volts on this before all that's happened on these so far as they've just gone off and I've turned the voltage back down again they've come back to life again which is quite good because if you do exceed the voltage it does say on the ebay website that you'll just kill it that little burn so let me let me just pause this for a second and cut those wires and switch this on this is just the just a quick test on that actually just what I've ever been said to I know sort of with the extra messy I've just been salvaging so yeah I just wanted to test that again actually 44 volts I'm pretty sure this one I had connected and it just went off that one wasn't connected at the time so I don't know what's going to happen okay let's turn this up a little time a bit so we got power yeah 99 volts there what's going on so that voltage is feeding this showing us 9 volts right and then this is all connected here a bit of a mess but it's connected there so the twisty wires are going in and feeding this which course then is feeding that LED just for the sake of putting the so you see the voltage I wasn't a this is a quick bit in between the filipino that I'm just making so let's just turn that up a little tiny bit all right so we've got that on and now I'm going to turn the voltage up and just to see what happens at 44 volts and we're going to be seeing 44 volts here I'm going to turn this off doing it oh it's got twin trim yeah so this is like the limit yeah it's still really great so this is like the limit so now but really we should be burning oh look at that it's getting quite bright just trying to yeah so I burnt one I think that's burnt straight away that one's going to come back on again but I'm pretty sure this one's dead let's see yeah so yeah and most definitely this one's got a resistor as well I'll take that off just to make sure it's the same as this so for the red red ones if you go above 30 volts in so what was that worth look back on the video if you go above 30 volts it dies if you go above 30 volts on this one it bikes out and comes back to life again when you reapply voltage within the given range just so I'll do that little check just so you can see on the video if I just pull that through there just to get those out of the way a bit we'll do that just get that out of the way so what we got here now is basically it's just this pile of mass so I just made these classes over here because what I've got on here is I got myself a little LED 10 watt LED from eBay and I've also connected to the LED this is wire here which goes off to this monitor and I got another one here which is connected here and that goes to the back of this tip 3055 so if I switch those on as you can see hopefully we've got one monitor there saying 24.8 and we have one saying 25.2 I just don't want the I want the lights now making it flicker on the screen so okay I think we should be on around about 14 volts here I can sort of look that says 40 volts at the top and see what we got we got 11.3 we got this one now this little this is a voltage regulated and current like regulated circuit and it does work I've got a little bit of an issue with it but it does it does work and at one stage it was what was powering I was using this to power these yeah to actually be for the lights but of course I'm using 3.38 and they will already take like 30 volt input really so I'm gonna swap those out in a minute I'm gonna put a couple of the um the LM317HV is there like this is here because even you know I can turn this up I can't like turn it up too far because it will turn me up too far what does it say 7.95 but we get to watch the we get to watch the temperature go up on the LED do that temperature goes up we also get to see the temperature go up as well I hope you can see that but the temperature is slowly going up on the tip 30.55 it's quite hard to see in the back of this camera it's got a very small screen so I hope you can see that anyway and that's no because we've got eight volts here we've got 10 volts now so what I need to do is turn that up a little bit more give it at least 12 to get 10 out of the other side about 12 volts turning up get 10 out of the other side the temperature is still going up on the LED I hope it gets brighter as well and of course the temperature is going up on that tip 30.55 as well you can see that yeah now also I'm just gonna switch this off for a second because earlier on I also had the my oscilloscope leads connected but I connected them across the capacitor there so I could so I could see the matter ripple you know as I turn up this LED of course I'm drawing more current which means I'll be getting more more ripple especially like I said these are rubbish these are old capacitors for starters and there's not very many microfarads there I think I've got more I think I've got more here on this one than I have on the whole lot here and it makes a big difference when I put this on I've got some bigger capacitors coming up I've ordered this I think it's three or four 10,000 microfarads you know for a power supply there's no bleed resistors or anything across here I'm not going above like 30 volts at the minute and it is just basically I'm just playing around I'm just looking for myself so I can see the differences when I have more capacitance and just you know because well this is how I get to find out what's going on with things a little bit just by experimenting so I just connect up this to this DC side a little like that and across here even though that sets 50 millivolts that seems to be you know I'm sure that's going to be a tiny true but we'll see how I put this on here and what we've got going on and I press the auto button actually I don't know what it was set for last night I can't be bothered to run with it too much the interesting to see what that brings up there we go so that's what we got look that is the signal you can see that okay why turn down that shoot you know that's one of the nine things about this this should be back from AC so I'm just going to auto that to see if it stays on AC I have noticed a few things I had to freeze up on me a couple of times as well I got a little back to the AC online as well and it changed that as well so so we're at 50 millivolts per division so about 100 30 millivolts I'm just going to change the acquire to something that's a little bit easy to see rather than average but normal just 100 millivolts that's 200 millivolts per division if I start pulling on that power with more absolutely terrible but really I mean that's supposed to be DC the DC signal forget the biggest one this is 475 volts let's just check out voltages in the end we're in the range we've already got 33 volts there 33 C 34 C there so 44 C there now I'm going to trip this capacitor across I don't know you're not supposed to really do more of this but as long as we get the negative to the negative thing we don't it's anything untoward a little bit of a spark look how much that reduces I'm going to take it off yeah that's the capacitor off capacitor on I'm going to get that balanced so I can get another one I got another one here of of course this is 680 nanoprose this is a new capacitor it's a nitchie kind of it's only 6 volts this is 100 volts this is a 470 monoprode so nothing that you can't let's put this on and see so that's with it the way it is at the minute I'm going to put this one on across there's one power on let's get a little spark I'm going to start to do this and although I can see a bit of a difference we may not be able to see that much of a difference together if I am doing this literally I'm just straddling the wires one lead over each wire I turn this down because that's not so bad I'm not actually you know sort of drawing any power I know if I turn the input voltage up as well so let's say I put this on 20 volts this is what I'm loving about having this water transformer I don't have to I've now got a variable AC and this is brilliant and because now I don't have to worry too much about you know I've got the right transformer for this I've got the right transformer for that I can I can just play around a little bit so we've got 20 volts there now and that's what it looks like with no load I was turning the millivolt to the vision and then if I start putting the load on to it just by turning like this at the minute it's on the one bulb but I'm not really drawing any power so I start turning it up I don't know if you can see across the top here but you see that amp meter that's the amp meter on the water transformer if you look at it carefully you can just see it as it goes up see that big jump there what is that that's on to the right volts half an amp oh and as you can see oh that's so not nearly enough I suppose they're not far future that and look at the mess of that and that's with the uh Ruby extra two capacitors though I would set those two capacitors off it's great on the little amp meter there because I never thought that was using so much power so if I take that off and if I take that this one from the back look at that look at the difference it makes it's just put in that capacitor and I put that long capacitor back on oh it goes here we're different somethings but now you can see that it says high because it's gone over its temperatures I'm going to turn it down before it starts melting that's uh 52 then I have to keep an eye on these temperatures because I think these cannot have an old computer system that says it goes up to 90c so this is way too warm for every minute dropping down a little bit on the um on the tip 3055 so hopefully that will come back down to I don't turn it off or together at all they'll a bit come back down to that level almost we can see that's come down so yeah and of course we're on back down there on the amp meter for the auto transformer and now we've just kicked back in over here 85 and dropping I've also got this resistor from this LED and this is just so I can um oh it's just stopping for so much current and heating up really it's uh I mean I know that was getting warm and it does need a heatsink really if you're going to be using it but the uh the LM317 doesn't get warm but that's great that we don't have that amount of voltage we'll be able to just like turn it up and turn it down a bit because I can't do up you know as high as what the transformer will allow but I just have to be careful of the input voltage because if I go too high the input voltage like by right now this could all be burning because it's got supposed to be 30 volt limit on the input voltage there but like I said we've got to resist there's only 220 ohm if we do the math here obviously we go up a little bit but it's not going to go too much more so I'm going to go down but I can put a lot more into this LM317 the HV it's uh I think it will go up to 60 volts going in there's probably differentials on it but of course I don't like the idea of running these things like that I don't like it thinking that I might just want to use five volts off it at an amp but have an input pre-set at you know like 35 volts will that be no good because there's a lot of difference there for cooling down all those volts differences between the five and then carrying the amp that's that's quite a lot of power to dissipate so being able to turn down the AC side of it means I don't have to regulate out so much power it means that whatever power supply I'm trying to build or whatever you know use for power in a particular project means I may have to like build it every time but I don't see that such a big problem and I don't I don't think that's such a big problem I need the experience anyway on building these things so but yes that's just what I've been doing I'm waiting for parts to do other stuff and of course it's been nice warm weather so I like to go out and do other stuff with people and talk with them and go to the pub and yeah I've got some other stuff I've been doing like here is a four different circuit protection reverse polarity I'll do a video on that in a bit I'm just waiting for a p-channel MOSFET I've actually got it to work with a I think that's a p-channel transistor but it works weird and I'll show you in the video explain it yeah so this is this is nothing really this is not a video sort of like trying to show you how to build nothing or anything it's just I'm just prepping around with these different things and I need to be making a power supply oh yeah I was going to say about this one well this is the same basically as what's in here except for for some reason for some reason I don't seem to have as much voltage control over this and that's probably down to these resistors so I like to have a little play around with these and I did notice on a few of the resistors I had sent in from China they were actually marked up wrong so there's a possibility I've got the wrong resistor in here but we'll end up doing this as well as I'm going to put a a couple of HVs in here because this the higher voltage 317s just because it just gives me the ability then to go above you know 30 volts and sort of 40 50 volts is quite good so it's not temperatures coming down on this LED quite nicely and it's going down on the on the tip 3055 so yeah I'll do some more playing around more experiments and when I've got some bigger capacitors it'll be nice and smooth out that so it's nice and smooth because like I said I start with one volt and once I start turning that up I'm going to turn it up it just gets that's pretty good the reason why it's jumping about is because it's on the AC it's keeping the middle of the screen yeah anyway thanks for watching guys it's uh I'll figure out something more interesting to them bring it back to you we'll just sort of meantime this is what I've been doing just running around with these things and like I said just waiting for parts and flying around my little uh my little sima x5c and my uh h501s which is watching bye
