 Yeah, YouTube Inside of the volume building softening on these little 555 Inverted circuits this time I've got a couple of PMP MPM The transistor's there I'm coming in with like 13 volts 30 volts Into this but Coming out of it I've got 5.5 volts AC Which I'm measuring there And that's coming off this this capacitor Which is connected to Both the emitters of those And their transistors I'm not quite sure How I've seen to have lost so much But anyway, so at the minute That's what we've got out the other side of the transformer Now that frequency sort of fluctuates a little bit We've what I've got here. I've had to get it down so I Could do a lot more messing around with these With these capacitors But the first one what I do Is I would change this transformer and put a slightly better one on because that one's only good for a Couple of watts, I think just for it came out of one of those little I think it's only the light It's not the greatest. I'm gonna try to change another and just see if it adjusts the frequency and What's going to try to see what's going on with this That's what we got so far. That's the output here. We've also got the We've also got the The output there, which is supposed to be a square wave, but as you can see That's not the greatest We've got 10 volts division here You've got 50 volts on here, but that seems to be the most we can give it Let's get rid of that menu So it doesn't look particularly very good at all But it does like bulbs LED bulbs that is, you know, 240 mains, 240 watt mains bulbs, not terribly bright, but We'll see that's not what's going to do with this, but I've got a funny feeling it's A lot to do with the fact that we've only got You know, five and a half volts I'm coming out of this and this always switches back to DC, which is really annoying I wish it would just remember where I left it because look if I go back now I'll start with the wrong one I'll change that back to the menu Back to DC again. No Annoying So I'm just going to change this round and I'm going to change that round Don't need that on there And we'll see if it makes any difference Okay, so I've changed that over And I've put my trusty toroid in there, and I made a slight adjustment on the I've set them both to 50 50 volts so you can see the difference between the input and the output, of course And I also changed them to DC coupling both channels I had them on AC coupling before so really I suppose now I've got to go back to the I just want to change something Contrast Anyway So The frequency has dropped a little target nothing's really changed on the voltage And they haven't put these back here To see what the difference is, if any, on this Back to that DC thing again. How annoying Okay It's not quite right, can it? The reason why that's gone up could be because We're going up very slightly there because it is a little bit dependent on what the wind is doing outside That's a scope display At least it's a bit better looking square wave than it was before Well, the circuit I've used for this And it pains me to say it because normally whatever I've got from this site has worked Here it is And I've made it exactly the same. The only difference is is I've got a little bit of extra capacitance here just so I can have the tune ability with the 100k pop Okay, just so I can get the frequency on 50 Hertz So if you look at it over there, I can play around with it Yeah a little bit We can go up a little bit with a hundred nanofarad capacitor. I don't have The tuning range and I can get this new enough bang on. Yeah, that's close enough just for playing with this But the reason why there's only 92 volts on the output Is because I've only got like six and a half volts around six and a half volts Coming out of this And then it's not being amplified by these Transistors They just enable some extra current flow So then I'm playing around about six and a half volts Into the transformer On a 12 volt input Because this transformers It's got two 12 volt outputs Here's the other output And sorry there's about five and a half volts on this We'll look at it again in a second And then here I've got my 90 volts 92 volts And it's not very pretty there either And the input there is set to 10 volts And The output blue Is on 50 volt per division. That says much second of it. I can't get 100 volts. I can't get any Any closer into that. Maybe there's a way to do it, but I don't know how to do it And let me just check that both of these run So if I put that on DC That's what I square where it looks like And if I change channel two Obviously you want to channel two now and we put that to DC That's what we got there So But even there that should Well, it's not really an 80 signal is it because it's just a square wave signal Anyway, so I don't know This is 12 volts 240 volt And I've still got about 13 volts there These what is here and what's feeding What's feeding this So I've got my 13 volts going in I've only got literally half of that What not literally but Around half of that coming out Well, we should actually tell this but I go into measurement Oh Wrong one. It's an everything wrong. So 8.4 volts We must be on channel Put on channel one put on to measure And that is channel one And that's channel two We can't see that No, it's a light thing, isn't it? Maybe if I Change the light thing there Can you see that now? But if I were to change The coupling of That to AC And then we go back to measure Six volts I suppose it doesn't help me. I don't really know what I'm doing I'm just You know, I just figured that no one's going to teach me Like in a school or anything. So I'll just I'll play with it and figure it out for myself Which is okay Do I put that back to DC? Just because it's more of a square way there. So we get to see What that is and that's on the output Of here But just here So I don't know if I don't know what's going on Um You know, I can connect up to a little bulb. I'll show you This is a six watt LED bulb And this is the hundred volts Just here. So I just put that in my hand there And grab this And so there's the other the other side of the hundred volts Probably about a little bit like that. Yeah, you get to see that a little bit flicker there um on Our 90 volts 92 volts. It says it's dropped down to 37 volts And as you can see maybe over there on the scope the waveform of course has dropped as well Up it goes Down it goes But I don't know I'm supposed to get 240 volts are that I'm not quite sure what it is where I'm going on, but It's just a basic You know the basic a stable 555 circuit Just to give that that output um, we just been able to Adjust the frequency to 50 hertz And then there's a little hundred ohm resistor there before it goes into the base of the transistors Uh one collector here this this this one here and he's going down to Ground the collector over here is going to the positive Yeah, and then we've got the two Um emitters going to the negative the positive leg of this capacitor one side of the Primary of the transformer It's negative the other side's coming off of this capacitor Which is connected here to these two wires Until the toro has been out the 240 Which would normally be the primary but in this case it's been acting as a secondary stepping it up transformer And there so I'm not quite sure how to get that to have more power so If anyone could help me out here, I've got a 10k resistor here. Maybe I could play around with that but Hmm I'll have a little go and I've done this already and I'm sure I had much better voltage coming out With a 555 timer. I need to go back and look over some of my stuff and See Anyway, I just thought I'd share that because it was Been quite a bit of playing around and just experimenting Cheers watching
