 Hello everybody and welcome back to my vlog, it's my channel, I just wanted to show you the progress with this now. I've got to put a credit up, I don't know how to say the name because I've forgotten it but I'll stick it up on the screen now, I'm going to give a credit to this chap and thank you very much for supplying your video, I did say that if this was done we'd probably get a lot further with this and I'm glad to say that we've got this far, so here we are, this is the board in in question, this is with a 90 degree, we've got our AC input, I can't speak for any of the voltages going in, I'm using 24 volts in AC and we've got our output here going to this little this little multimeter, so these are the what look like, let me just zoom in on them because they don't look too fakey-fakey, I don't know how well you can see that, it doesn't really matter but these are supposed to be TI chips and the one that we're going to be looking at in question is this one here just north of the variable Trimmer, and what we're going to do is I've ordered some genuine parts, I've ordered some genuine parts, these came in from RS yesterday and we're going to take one of these, pop it in there and see if we get the voltages up real quiet now, I'm just going to turn this on here and you can see here it says 25 volts, I can't go any higher, I can go down with it, you know, from zero out which is quite nice and again if I turn it up, there you go, just will not go up any higher, 25 volts, it was never about whether the board worked, it was where it did as it said, like it says quite nicely, up on here it says zero, zero to 30 volts and that's what we want, we want zero to 30 volts out, I don't know if it's going to be zero for 30 volts, we want zero to 30 volts, so let's get one of these babies out, I've bought a few of them because I've got a few of these boards and I'm not going to do them all today on this, this is the one that I've got really there with the ability just to change these out if I need to, whether you might want to change all three of them out, that's going to be your choice, first of all we're going to see if we can get this to do, now I don't know if I'm wrong or not, on the video that I'll put his name up again, shared, I couldn't tell whether he got two boards in on his DIY supply and so we got positive and negative outputs, which is very good, that's what's the good thing about these is you can make one of those supplies quite easily, I don't know whether the second board works as it should, I don't know if it worked as it should, I'm not going to stick out, that's the difference on those, you can see that so well, oh there we go, there's actually a new version of this, TL081, this is a CP, there's actually a H now and I don't know if that would be better, but apparently it's got some more parts on it and it's just the instructions in it or something, it's just an easy swap out, I don't know just rambling on while I'm putting this in, hopefully without being the leads too much, can't seem to get my hands to do what I want, it's because I'm not in close enough, unfortunately near my eyes, I got to get pretty close to these things, so let's get that in there, alright we're in, it is in like flim, let's put one of these back under here to help, just hold that up, I'm just going to turn that down, we've got that, brilliant, yeah put that on, okay this is a millivolts, it's a 60 millivolts there, we might need to do a bit of a trim out on this but let's see what we get on our voltage output, 5 volts, 10 volts, 17 volts, 19 volts, 27 volts, 31.6 volts, there we go and I've got a funny feeling that 0.6 will be trimmed out when I find one old trimmer and yeah, but there you go, I want to see if we can find this little trimmer or the screwdriver end in there and just see if we can do something with that on this part here, can we trim it out, I'll just get that on there, yep we can trim that down and get it to as close as we can to zero, whatever it's worth putting in, oh that gives them a minus one, well let's just take a peek at the output again, 31.5, there we go, winner winner, chicken dinner or whatever the saints are, so you guys out there that have this particular board, it seems like that this one chip here, if it's upgraded, in some ways I'd say possibly do the three, I mean you can buy these, these are 40 pence each, 40 pence, which is what, 40 pence, 40, 55 cents, 50, I don't know what you have in euros, that's a dollar so that's going to be a cent as well, isn't it on pennies, I don't know, but they're cheap enough, they're cheap enough to do that little swap out and if you had to do the whole lot that's £1.20 whatever if you had to do the whole lot to get that right, but that's brilliant, now we can say that that is now given as it's supposed to and it's crazy because it almost seemed like it should have done somewhere along the line, it should have done just because no matter how much you look, apart from the change around of the voltage regulator and the two pins out, there is no change on this board from the other ones at work and the connections are all as they should be on there, it's all a proper little headscratcher of course until you get down to the Chineseium, from what I understand it's something to do with the null offset on pin five and that's that, it works, I called them fake against the highland ones because they're not stamped up as being highland but it was mainly non-working boards, non-working as they should be and now we can get 31 bolts out of it, so maybe that now is a big thumbs up, big thumbs up to the chap who shared his video and yeah, go get them, get all your boards working, have a great day, catch you in the next one guys, bye for now.
