 hey there youtube okay so in front of me there this here is um this is a linear power supply it's one of the banggood power supplies not 30 volts i think it's like two milliamps to three amps um now i did a video on not the build as such uh oh that's a lie i did the video on the build of the board and that was quite a while ago and then i put it in this enclosure sort of and kept taking the transformer in and out and then yesterday i did a video sharing what i've done inside and it was in two halves and the second half the camera went a bit yamping on me again i thought i'd actually figured out this camera but i haven't and i was doing like a load tests just to see you know what it was like trying to drag a couple of amps out of it and uh for ripple using my oscilloscope it's pretty done good i'm quite surprised actually but i can't show you that because that wasn't in there but just at the end of this little segment part i'll show you the insides of it i know it's all set up there now but i've already done the video of the insides and i'll just attach that onto this but before i actually lose that or um because my channel was more about my lug you know and what i'm doing it's not really a tutorial channel or anything like that i'm not um i've not actually got around to inventing anything yet or it'll be great if i could but it's more of a log it's my progression log on you know this hobby electronics and um and part of that is you know building into these enclosures and doing bits and pieces and every time when i do it i learn a bit more and try and improve and although i've not made great stride falls i'm improving um there i'm getting better because if you look back a year of me doing this and you see the first little power supply available um you know i've advanced quite well and and that's what i joined youtube for was to basically see if i could use the internet and the resources of youtube and and the like to learn electronics and to get into this hobby and make it into a a lifetime hobby for me you know something for that's something i'm gonna have an interest in for the rest of my life so um you know so far so good it's i should make a video maybe about the road so far because it's got its ups and downs um it's not all just clean plain sailing and it's such a massive um subject as well if you think about it i mean if you think about just from a component about the component how it's made um and then you've got all the physics see types side the equations and maths and everything else wow and then you've got the equipment oh and that's even before you learn how to read a schematic or or um put put a circuit together and test it it's there's just so much to it so i digress a little bit but so yeah at the end of this uh well this little tiny segment here i'll just show you what i've done on the inside now it's not like the professionals do i've seen a couple of other guys on here and you know they do it very smart and and etc i'm not like that like so i'm just a year in maybe in 10 years time you know i'll be at their stage maybe and mine will be great like theirs but so i just want to at the moment i've not actually got a plug on this it comes down into this which is working out really really handy because i can connect my little adjustable transformer ac transformer up there um which i've now got my voltmeter on and that this is all bolted together now so when i pull this out the whole unit comes forward it's all bolted in lovely bolts there but it comes into this and i don't actually think that's plugged in so i'm gonna just put it into well i've just plugged that in so a little neon lights on um and we've got a fuse in there it's break too high really for this little circuit um but it's you know it's okay it's okay so if i just plug that down these things are absolutely brilliant i'd say to anybody you know you want to get yourself one of these because it's just don't know i've made life very easy up here but now to just connect stuff in that there's another a plug in it so i switch this on uh and this will measure up to 10 amps now in the video when i'm showing on the inside it'll explain that the transformer i have got in here is too big really this is a three amp board the transformer is capable of putting out more power in that so if i were to put a big load on it uh the transformer will try and dish out the power up at the board will die in between and i do explain that video that i don't really mind that so much because even though i'll be very careful about what i put on here and i am going to put some resettable fluses in to govern that out for the power if i can and i'm also going to look for a transformer which will just do the job you know be the three amp but to be fair this this one cost me 19 pound that's in here but i think it's like five and a half six amps and the three amp ones are nearly 30 pounds so i i've got the little led there that was on the board so i've got my current control um i do really good and of course we've got to be full power it'll go up to 31.6 volts let's turn it up we've got a 10 10 10 putt um now i should probably it's not a straight on the 10 10 born it's supposed to be 10 10 putt that i've got it's not a straight um you can't just change it over those 10 10 k parts the wiring's slightly different i think i've sort of explained that inside the um if i turn the amperage up there a little bit you'll probably want to settle out and warm a little bit in there so there's a little bit of fluctuation there i'm sure that will settle out anyway of course like i said it's all current and since i can back that current down and forth there we go uh yeah so um basically i'm just yeah like i said it's just my lag and i'm just um i'm gonna have that as my linear supply and that means i've got two that work on the mains and two that work out the batteries because this one works off the batteries the solar batteries and this one works off the solar batteries because i've got the boost converter in here first to take up the power and then this drops it down it gives me a lot of control which is great if i um that's probably gonna be on if i switch this on so i've got the one down there as well which is great for the lower voltage stuff because that's that directly from the batteries and this one's great for when i do when i do the high voltage stuff because flip this on and we've got this uh nice bit of power supply there and of course i don't this will take maximum of 60 volts in and this of course will give me like 85 and a half volts basically out um when i've got a little more power on the battery will give me that but if i were to use this now with that like that it would pop it if that wouldn't be very good at all so yeah off like that so i'm i'm quite chocked with this i'll do a video on how it copes with the power i did do one like i said but i've i've lost it because this little camera i've got starts going a bit yampy and then it doesn't save the actual file so um you basically just lose what you've got but i have got part of it and i'm gonna join that now to the end of this so cheers watching and um yeah have a little look on the inside of this okay so i've been playing with this little uh this little uh like linear power supply circuit these are the ones that you can get from banggood i think they're about eight pound at the minute i got this one it was less than seven pounds so but i've had it for a little while and i've been putting this thing in taking it out putting it in taking it out but i've decided that i'm probably gonna sort of have this as a little linear now it's not as you can see you know the best of setups but then i don't profess to be the best of setting up her best setting up her et cetera i don't know some proper words in english uh i wound some extra wire magnet wire around because this was ideal for powering this um display but i couldn't find i made a little board up five volt regulated board but i just thought to myself well what i can do is i can just take it off this 24 volt coming out of here put a resistor on it and that'll be okay you know for the board it's got a 229 resistor i'll do the map and i'll put it on the on the screen you know when i've made the video just let you know what's going through it here but it's not you know it works it's okay and i've got a i got a couple of fans here i can't remember where i got this out of some power supply from a server or something i can't remember but i've just used the same gunk is what you use putting capacitors in because that's what's holding this all down to the side to the bottom of the case and it works quite well actually i could pick it up and shake it around it doesn't come out these elastic bands aren't really needed now because these are actually gunked to the edge of here but i'm just going to leave them on there anyway because once i put the top on no one's going to notice and it's going to be facing away but i've put a 220 ohm resistor there as well five watt one because i noticed with the two watt one it was getting quite warm but the five watt one hardly gets warm at all but it just means that these two they're in series and i'm putting off that 24 and they don't particularly blow too fast or loud but fast enough to make this a different temperature you know cooler so that's that's good and the only differences i've done with this really is you know i've got a 10 k pot here for the volume for the voltage i mean i've not widened the switch just yet it's just going directly out the back of here into here and this transformer is it's got more capability than three amps and they sort of say that you should only put a three amp i think i'm putting this three amp max transformer but i think i can dish out about five amps or something i'll think about what i'm going to do and that probably do it through fuses and i've got a switch in the front of this anyway i put that in before i put a little hole in it's not quite full it's just i use the rounded head type thing at the back so the led fits in there it's a different led it's still a red one because i'd actually put it on the board and rather than i did try just to unsolder it from the board but it was a bit of a pain in the back side so i just ended up just snipping it out and then just put in this wire hey see okay put in this wire on um and that just goes down there look as you can see sorry about the light it's a bit terrible isn't so anyway um and i've made the adjustment i used the old to calibrating so on here we've got zero folds when it's at zero i'll show you that now so you can see those fans spinning around but you know how to hear it can't hear it it's all those plenty of plenty of wind coming out there and i can hear it oh i've lost my stick so down here we are you turn it up nicely and if we want to oh yeah these these knobs now i bought these i bought these quite cheap rather boring very cheap for two of them i think it was like two pound thirty five including the shipping and they came with these knobs but one just falls off this one that's no good and this one i can't actually get to go on oh and this one's just fell to piece oh one of the last ones live in this screw maybe it's got something to do about screwing there i don't like them anyway they're a bit annoying they sort of i just feel a bit weird and i've referred to in this but i might just find another another knob for them but i've got knobs i can put on here but look we've got the little red light will come on i might put them on here it says oh i suppose that's because uh let me just put that on there just to make sure we got some pressure there and if i turn that up a little bit so we've got well 2.84 there 2.87 there they're not you know greatly accurate and these these two are going to be different to each other but if i turn that down all the way to zero we should have zero over there it should get down to zero because i've already calibrated this in because i have to give it a little bit time for it just to you know just warm up a little tiny bit but that should get down to zero he says i might have to just give him a little bit of adjustment but i'll just oh there we go zero just dropped me stick i know why that says one milliamp there when that's supposed to be all the way down and then when i when i do turn it all the way down it says like minus you know 0.53 we'll just give it a little tiny little red light stop it from yeah i'm pretty sure it's supposed to be like this now what i'm gonna do is i'm gonna do uh i'm gonna put my scape on in a minute i'll let it warm up first i won't be filming i'll do that i'll let it warm up and then we'll do a little bit of ripple check because he's only got like a yeah there's a couple of little tiny capacitors down there a little 47 uh mics and there's a few uh tantalum tantalum tantalum i can never say that word i don't know why a bit like lemon lemon lemon but nothing's getting like particularly warm i suppose that like 24 volt is slightly warm but it's got a bit of a heat sink on there so just keeping on that yeah you're right it doesn't get any warmer what this five watt uh resisted is there but we're gonna stick a load on it anyway and see how it goes from there and i will get the switch wired up i just gotta consider the fuse for the my fuse and stuff sorted out for there but that's going to be the interesting part what will he do under the leg what will it look like on the scape you know when we put um when he's drawing let's say two and a half amps or something and just see what it looks like because i've seen linear regulators um and they need some they need some capacitance on the input you know to stop the input ripple and i've got some look at that baby that's 10 10 milli powered you got a bunch of them okay through today very nice but they uh they're not gonna fit in there that well i mean get the wires parallel underneath there or something i'm not sure i don't even know they're gonna be needed to be fair let's have to see uh see what happens because you know i'm pretty new to all this stuff anyway and i took out the other i had some different ones of these in these but the problems with these is that there isn't you can't like unscrew them and then just wrap a wire around where on here you can you can unscrew these nice and wrap a wire around they've actually got holes and i might have to well i will make an adjustment left it just slide this out and adjust it to the holes uh going through the top you know so i've got a piece of wire i want to put it through the hole i can actually see how the minute it's out the side uh which could be okay on the side i suppose i don't know this one's at the top so it'd be nice if they're both you know the same but i can still wrap the wire around that be quite nice and you can still use the banana fittings and i'm not sure if it's the the standard correct size because i don't actually have anything you know manufactured that is got the standard correct size to compare it to uh i haven't got any of those um types of adapters anyway so i don't think it really matters but not for me it doesn't matter you know some people might say well that's a lot of rubbish because i haven't done it to the right sizes but then there's a whole load of things i haven't done to the right things in here so you know people can't pick fault with it it's easy to pick fault with it i'm a complete another amateur and sorry my uh my frame was flashing i mean i have to just answer it um where do we get to uh 45 pounds which is uh basically what this is cost me to put together um i could have bought a cheap uh switch mode but this is a linear and the nice thing about this is you know i've got a bit more experience on uh making up the uh the company the um uh the box the enclosure the nice thing about it is if it does go pop it's an eight pound replacement this gets quite warm i'm a little bit worried about these wires here but i've decided that i'm gonna put a load on it a bit and just leave it going for an hour or so and just see if there's anything detrimental happens to these wires if if there is what i intend on doing is because these are just like hookup wires and pressed onto these connections i can just undo them put some heat shrink around that i probably won't heat it and i'll just put them back but have it as another barrier between this and the wires um yeah so that's it that's the little power spot i'm gonna power it up now uh my connection here isn't so great because in hindsight if i were to redo this now which is another advantage of building your own um i would move this down slightly and probably try and put in one of them proper connectors but then in some ways part of me argues well why should i because now i have a big wire sticking out the back and but i suppose it would be better for transporting but i've still got those options i don't intend on moving anywhere just yet and i would probably have rebuilt this i'll probably do it next year give myself a year and the way i look at it is this time last year the little power supply i built on a breadboard was basically a voltage regulated power supply with a little tiny transformer just to play around with and now a year later you know i've done this as well as others uh and then a year is time and i'm gonna do more i'll do it i'll do it better maybe i'll treat myself to another case or and set the same sort of thing out again but in a more professional manner as i get more experience and and that's that's the way i intend on doing these things okay i'll just give you a quick demonstration of just putting it on and i don't you probably it's uh pretty much no one to expect to see that while using this through here of course i've got a switch and then there's a fuse built into here anyway it's too higher rated for this but and even though i've already got a connector block here if you see i'll put some of that salastic in the top so it does make sure that the mains there is is isolated through there so that is a little bit of a safety thing going on and this is all salasticated in i don't know if that's a word salasticated it's that white stuff that you put around capacitors anyway and i put a whole load of hot snot or hot glue around that as well just to um just keep it there just keep you there but it's probably gonna sit on the top of there as you can see i've moved all the stuff off there and i've placed it there once see what it'd be like and it seems like it might be okay then quite a handy place to get it and it just means that if i can't use the batteries over there and the batteries on this one um because that's a linear and that switch mode i can use the switch mode powered from the atx so you can see that that switch my power from the atx and then i got this linear one that'll be powered from the mains as well so either way i'll i'll have power batteries or not i'll still have some power and two of them because you always find two power supplies these two outputs can come in handy okay right so we got that on so switch down there's no real noise from the fan it said that 9.29 volts uh 9.3 really is what i was looking for for it because i'm gonna build up a little kit and that wants 9.3 volts to power it this is pretty quiet but there's a nice little airflow there and this does get pretty cold it's a lot colder than everywhere else and again this one feels pretty cold too and i'll uh i'll stick a load on it if you just bear with me
