 Hi guys so here's another kit from my friends in China now this is a this is a kit I know it works because I've already built one and that's always nice to know isn't it, so we're going to get work and we've got ourselves a circuit diagram for anybody at home that might want to just sit and build the room and these are all the parts and everything's put in there so and here we go with this okay well you know to be easy it's gonna be easier I think just to just to look at the board but it's all pretty much yep it's all pretty much easy enough to see what goes where so we know we've got a tip 41 in there which probably does that's the IRF 530 tip 41 a couple of these heat sinks you've got some nice brass standoffs set it off the ground this is for our primary turns as that looks like it's probably all there I don't see why they won't be we've got two 10k's, two 2k's, tip 41, a couple of 3 mil LEDs swap them out with a different color but just remember that these reds take less voltage than others and we've got a 350 turn end up to coil there and JT that's just the connection isn't it and then we've got our M3 times 10 4's four of them we also have 105 which is in that's Puff because it's capacitor we've got a one micro farad two to three turns for our primary DC input M3 times six oh we've got six screws five screws one our six screws in because we've got two for these uh two for these heat sinks uh 25 by 23 to one of that is all right but to be honest with you there doesn't seem to be anything missing from the other one oh and there's this is where you get a little neon light a little neon okay so let's put it together now like with all these kits always go with the smallest pieces first so we know we've got two why don't we've got two 2k's and two 10k's so i'm gonna be going to see the difference but there's only four resistors and these are two of these are together so we just got to figure out what one of these is now i'm gonna say this one is a 10k let's have a look meter this will do it a little bit of resistance sorry there's loads of i do like these you can buy these pretty cheap on ebay you can buy very expensively on amazon uh you're in the uk but you can buy them very cheaply and anyway there we go so we've got our 10k there i'm gonna just just check these just make sure that they're so it's supposed to be 2k 2k right 2k okay 2k is okay right so let's do these two in first then and then they're gonna have r3 and r5 there's that 2k one bomb we've got r3 here 2k nice and easy well when you bend these uh well to be honest with you i'd never come across a problem of bending them i suppose you should always just be careful because you're going to damage the compound but i guess you're probably neither anyway and we've got to be up here r3 and r5 so r5 is there just makes it a lot easier for me anyway just to do like this put them on and then um just solve it up i'm not going to change anything and it's not a bad little circuit actually i mean this is just like a standard uh it does a circuit but you can use audio now i must admit when i tried using audio uh with my little my little samsung s3 here because it's got a uh got a headphone jack in it it just switches off the movie player the music player sorry you know just turns it off doesn't allow any output and my i've got a samsung s21 and of course they went the after taking the mickey out of apple they went the apple way anyway which was to get rid of the microphone here the headphone socket and uh which is a pity because i liked the headphone socket before and the samsung but there you go i suppose it's for our the best for our safety or something like uh so we've got this one last this one last 10k whatever is left there's only one hole left so it's gonna go in there uh if i can find it do you think you might fit me always not i can't see the wood for the trees yeah so it'll be interesting to see if this one actually plays i don't i mean i could try it with my computer but i don't really want to plug this into my computer we've got a capacitor there we've got that where's this coming through i suppose you know we are you know i don't know enough i've already killed one music player playing not with these circuits but playing around i made my own and uh if i'm not my own it was a copy of the circuit and you know i just could see it did actually work a little bit but then blew the part blew the little uh uvio u o o i or u aio player that's quite a bother go mind right so we've got leds now uh anode cathode to the shorter one or if you can see inside it the bit with the biggest metal plate or it looks like a metal plate but the bit with the biggest amount of material inside is the negative and the longer lead if you have it as a new one is the um is the anode so the anode is the bottom of the triangle the cathode is the the marking across it the line across the top of the triangle so now these i'd be careful with when you're doing these because sometimes these leds uh can be a little bit a little bit um delicate so i'd just be careful when you're doing that i mean i don't know the other ones i'd put it all the way down to the board near enough but these i leave a little bit of a space there because i'm just trying to keep it out of the way so again you know the longer lead down the bottom and the cathode lead the shorter one at the top there i'm gonna add a little capacitor what's this not very big at all is it i mean physically it's not very big at all which i see is made by reckons it's uh one micro farad 50 volts made by sw so on this one you can see on on here there's our c1 one micro farad and the positive side there is a got a little positive thing in there and all this side is white and that will go with the the lighter side of the capacitor so i'll just put that in and again the positive look it's got the longer lead shorter lead on the arm negative side okay and there we go a little yeah 105 yeah it's even five puff it's got to be a micro farad or something there all right so we can just quickly sort that up i mean i suppose we could if we wanted to we could what i do with these is i'm not gonna bother putting any paste on then the coupling to this should be that should be enough for what they'll be doing but if it does need to have paste for any reason it seems like it's not coupling enough let's say the uh the transistor itself or the MOSFET is getting way too hot and the case isn't the heat sink isn't then you know couple it up with some thermal coupling paste but just for this i'm not gonna i'm worried about it too much i just find it easier like this to put these on first because then when you come through the whole you know how high you know more low the leads need to be i'm pretty clustered on but get it done all right so this is our tip 41 tip 41c i know it's gonna face inwards just like on the diagram i'm just trying to shade the fins of the heat sink i'll just fit into those three holes as long as it's legs uh those leads are uh are good and then we're just gonna poke it through ready to solder up we'll just do the same with the next one same thing applies if we look down there we're like that then we just flip it flip it and then we're gonna solder it flip it and solder it right just need some power over there so yeah there's our uh standoffs and sit that on um we're gonna put these on even though you know yeah we're gonna put them on just put like now this one could be a bit tricky what we're gonna do is know which one's the top bit and which one's the bottom and i'm gonna say this bit's the top bit and the reason i'm gonna say that is because we want the long bit on the top yeah because as this like has that little bit of uh a breakout on it um it's gonna burn the metal then this will get wear away it will go wear away so if you have it this short of it there you're not gonna have that much but i suppose you can always keep pulling a bit out just keep taking take off a turn if you need to but i'd have to check the other so your orientation of it because we need to get that correctly around that's easy enough i mean whichever way we put it on if it doesn't work then we'll just rewind this the other way the way it is and solder it down again it should work and then once we've got it you know working um we can then tune this let's say or make it look neater depends how yeah how you like these things let me show you what i mean it's like i did this one like this and you know it maybe works a bit better different maybe an extra turn or uh maybe it does work better but as far as i'm concerned that looks okay and it works and so yeah well good did these some of these coils i must admit there's a couple of nicks on these coils i'm just a little bit worried but we're just a little bit like that and hopefully we don't have any damage well this one looks okay looks good looks good looks good all right the soldering on should be ready i stick this on because i just think it's good practice for me as i do quite a bit of soldering and that just sucks out for you yeah then the soldered and yeah because i don't really like breathing it in i mean smells really nice but you're not supposed to breathe in it um right what's that gonna mean right look i'm just screwing on that whoa go back a bit i can't see me getting any better angle or anything i'm sorry about that if you wanted that but right so it's gonna go basically i'm i'm just gonna solder whatever pins are exposed to me making sure that i spend as minimal time on it as possible because we're just gonna do a little bit of a quick snippy of the ones that i can see that i've done these can be quite uh oh i need to stop drinking don't i see my hands i can only get over where i want to um yeah these can be quite dangerous you know when you're clipping away with your clickers because you can just ping all over the place and you know you're lucky you might not stick you in the eye i've got a couple of cats and so i try not to get anything on the ground because like when they come in they're running around like lunatics i don't want them to like you know get anything stuck in their paws so i tend to just like put my finger over the end of it before i blink it and then blink it just means that i got it and it doesn't shoot up anywhere else and it's just easy enough for me to chuck into my uh chuck into my little bowl that i keep on here so the thing is with these sort of things you know when you're really doing anything like this just take your time take your time there's no big um no big rush to anything any more lightly it's not making a mistake like you know leave a pin or cut a pin before you've actually uh breathing those cats see with this better no it just looks a little bit better alright i'll do it all right so now i suppose the easiest thing i'm gonna do i'm gonna hot glue all i'm gonna do is i'm just gonna put some hot glue down in here and then just place the quill but before i do that i've got to decide i'm supposed this is gonna come down into it here and what i'm gonna need to do is because this is a mammal so you need to take off some of this enamel i'm probably gonna just use a sharp knife um oh you can see actually there is a little bit that's already been taken off by the looks of it so if i just there it is look yep i don't think you can see that can you see that it looks like a little bit it's been taken off again don't know there you go like might be able to just see it there that's okay you don't really need to do that then i've done it for you already i've done it for me done it for us very kind very thoughtful i've got no chance of doing this with my eyes i need somebody else's eyes help me so i'm gonna cheat on it i don't have to bring this down so is it interfere with the camera that doesn't mean i didn't realize that i thought it was like my other one but it kept making the camera have lines go through it she can be quite right i think what i'm gonna do is yeah that's where it's gonna go i'm gonna pull it all the way to this side and then pop it through like that but i'm gonna get the get the heat the hot glue on the go because we don't need some hot glue my guys here so we've got the hot glue in and what we want to do is we want to see this dribbling out the end uh before we're gonna use it otherwise it's just not hot enough i know that's uh sat out in there slightly that's because i i helped it out so that's just about it would be nice it just like just drizzles out slightly you know it's nice and warm that should be okay all right let's just get this in here yeah hopefully that should be okay not too much not too little bit on it just to build up on the inside a little tiny bit let's get this don't worry if you don't get it exactly around the the circle in the circle i don't suppose it's gonna matter too much let's go up this piece of wire now a little hole there you go beautiful not gonna be sticking out of there just gonna chuck a chuck a little solder on that so that's nicely put in there all right and this of course will be sticking up uh we need to take that off in an element it's not very straight is it never winds i mean i've only put minimal solder on it really because uh in some ways i like to keep these things you can think sometimes what you pay for these things go up and the heat seems to probably cost about a minute so we can just pull this off nice and gently really careful so don't damage anything pop that up in here that's where we're gonna get a little bit of crown rough uh now the next thing we want to do is our coil now now now let's just take a little poof and wonder at this one because that went round that way let's have a look so our coil this coil is well to be honest with you it's on sort of anti-clockwise uh let's look from the top on this one to be just not true yep they both are going around this way like if you're looking at them like this anti-clockwise which means then which means that we want to go the other way with our primary where this you always take pull this off a bit the only one that we're doing let's look at the one we're doing let's keep on this one um it goes around this way so the other one yeah we want to start it off here and bring it around the other way or finish it off in there just like I did with this one here so you put them in the opposite way yeah the opposite way so let's uh let's kind of release a wire set up for that the old uh they do you plan on your wire don't they and this is solid core as well so don't throw it because you might want to use this as like hook-up wire you know i'm going to go uh breadboards you know psychic boards pretty tight i don't know if you can actually say it's pretty tight on the board but anyway so yeah so we want to go um the bottom we're going to go into here and then we're going to go round and round like this and then that one is going to go into this side here all right now it looks a bit messy but it seems i pulled this off the end and do it let's see what i mean i'd say you get a bit of solid core wire here so i'm trying to twist it together there's only one in there let's just hold that through there just give a little bit of a little bit of salt on it nobody's still see that okay they're all in salt i don't tend to mess around with a wet sponge with my soldier i prefer the like the brass wall don't bother with that steel that steel wall that's like rubbish doing the sorting it just ends up breaking down and one of your turns neatly, if you can, the actual insulation on this should be enough for your distance between you. That is something you'll have to play with actually and I think I might, I think what I might do with this is just for the sake of it, put all this wire on and see what the difference is going to be by just having three turns and let's say whatever the max of this is, just for the output, both of them, on a standard supply, let's say, what they reckon would 24 volts, doesn't it? So let's not do that, we don't want to just burn out the top real quick. Oh look at that look. I mean look at the difference on how much you've got to have in there to go to there. With a bit of hot it's not keeping this in place. We got ourselves six turns I think, one, two, three, about six turns, yeah six and a half turns. That's pretty good, so all we're going to do now is get this off without just yanking the whole thing off. So I'm going to very carefully bend that off, bend that around and push that through. Yeah I could probably turn that down a bit later actually, can I? So it's a bit more just directly into that. I wish I'd left the hot snuck going on now. So I'm going to pinch a bit off, just got to be careful when you do this because if you cut too far into it now, what you'll end up doing, snipping it too short and then you won't be able to get those extra turns on. But we're just going to see what happens because there we go. I was mainly trying not to pull the coil off more so than anything else. So you know that can just stay like that for now, okay? We get to play around with that and see what the difference is. We've got the other one done there and we can see what the difference is on power output. It's more how that be fine. That will be fine, right. Okay, so now we can just pop in the standoffs. Let's see where we go with that. A little thing up, right. We need the soldering iron anymore. So we'll just stick a bit of clean off the tip, a nice bit of solder on the end just to keep it nicely tinned up. Just while it carry on sucking that away. I'll just push my, if I can get my hands around the bottom. Just push the screw in and do this up. It's just as easy, probably easier, you know, than actually with the screwdriver. No, everything's going over. Let me just turn that off. That up. It makes a bit of extra noise in here but I'll tell you what, you know, I don't know, I'll keep the leg fumes down. When you're doing, you know, boards with quite a few components, it's really nice to be able to do that unless you've got a bit of fresh air thing going on but unfortunately people are quite noisy outside. That's why sometimes I like leaving it to later in the evening to do my videos but now I tend to talk a lot quieter just because it's later in the evening, I suppose. And it's generally pretty quiet here anyway. So I tend to have a, everything a bit quieter. Apart from in the morning, sometimes I want to go and listen on a Sunday morning to some music. I like soul, you know, stack to soul, that sort of stuff. Some of those sort of bands from the old days, 60s and I love that sort of music because it's just really nice to listen to. It's got something to it, you know, some content, some hearts and soul. Okay, so we've got this little neon light and that doesn't actually go anywhere. I think this is just for us to hold and it will glow up a little bit when this is working. So let's give ourselves another bit of power. Now if I remember the centre of this is, what does that say? That goes from 15 volts to 24 volts, right? So we'll put it on 15 volts now. The centre of this is positive. And this one, this one, it's with a stripe on it. The positive, okay, a little power for here because it's already connected over there. It's just going into a cheap ebay supply. What we're looking for off the end of that is any, oh, there we've got a little bit of discharge. That's nice. Oh, and our little neon light lights. Look at that. That's what it looks like about these. I think this comes on and off when there's music going through it, but you can see where it's. I'm going to turn that volume up a little bit by volume on the voltage. So this is now on 15 volts. Okay, that's quite a bit and you can see the corona just a little tiny bit there. I'll take that to the side, maybe, behind there. And it says up to 24, so let's go to 20 volts. I'll be more powerful as I get in. Oh, that's quite good. Good intro, eh? Intro or so. So let's put on some of the 24 volts. And we're only using, right, now it's gone up to 300 milliamps. That's 24 exactly on there, which is probably not the rate as the 24. I want it to jump. So you can see there the corona, but you can just imagine as well, that's going to reach through that pretty quickly. But we get about an inch and a half there when it comes on. Now I'm just going to pack it up a little tiny bit just so it saves. I'll back it down to 14 volts. It does work with 14 volts. And you can still do the little, you know, this. Let's be honest with you, you don't really lose that much distance. I mean, you do a bit, because there it was blittled quite well. And you've got to go in that far. But anyway, I mean, it goes to show. I do wish I had another cable now. I know I've got one somewhere. Back out, pal. Intro was pretty good for me. There we go, that's enough for that. We know it works. Okay, well, we know that one works. Okay, so we can see that works. That's pretty good. A bit of audio out of it. I don't know why I put it up on this. I just saw it would be easier. Very hot. A little bit warm. A little bit warm. I can put up just a little shower to put a little bit more. What else can we do with this? Oh, we've got this. The good old plain and the fluorescent tubes, of course, that's always good for these things. A little party trick. I could also probably stick an LED on one of those coils and get a bit of transfer over one of these, because we're not really on that. I don't have to play around with that another time. I just wanted to show these little kits, at least some stuff. This is from eBay, these kits. I think I bought four of these, three and a half pound each. I'll put it up on the screen, actually, so you can see where I got them from. You wanted to get some yourselves. Yeah, good little kit, good little thing to build up. Okay, so we'll ask that. That's the little test with that. That works. That works fine. It works through on the audio. I don't know why the other one wasn't doing what I expected to do, but I'll try to look over that and see what's going on there. But that certainly does work, so there we go. That's enough of that. I'll catch you in the next one.
