 I'm in the plane around this little circuit here, oh this is, I've got a little bit of extra light on that, it seems to flicker a bit so it doesn't make much difference. This is basically a flyback driver using a 555 timer AC. Now although my configuration here isn't really that effective, I'll give you a quick demonstration of how ineffective it is. First of all I'm just going to turn that on, you can see that's a square wave line, half again. And I'll just connect up this wire, I'm going to fly back here. Now what I see is it's not very good. The design that I'm in should sort of copy and I couldn't, I haven't got the same MOSFET as what they've used. So I've just been using a, I think it's an IF840 and I can't remember offhand I'll put in a note or something on the video what it was the MOSFET that it said to use in the circuitdiverant.ly. I'll show that in a note. So I'll just very quickly then because there's only the little tiniest of heat since I'm this, turn it on. Pretty lousy really. Now I'll just turn that up fully because we've got some variable there but I've only got one. I'll turn that back on, not now. Okay, so I can play around with that. I've got some, actually I'll try to, this is a 3055 and a 220 package. I'm sorry, a 2N3055 and I've also tried a TIP35 in here. But it's still, it's not that great even when I play around with the two variables there. The setting then it's on at the minute is the highest frequency which is around about, I think it peaks about 110 kHz and sort of about 85. It goes down to around about 4 using both of these. Take it all the way down to about 4 kHz up to that right. When there's nothing on the circuit, when this flyback isn't on the circuit, it goes to about 43 kHz. But the way I've got it set is to try and get the most out of it. So as you can see it's not, it's not particularly that great. I haven't got the probe on my life. I'm going to turn the probe off. Oh, because it was going to there. Let's go straight to the output. This is just on the resistor level of the output. So let's turn it on. See, right now you can see there now look. I'll pull that round in front of that. Let's get that out of the way. See, okay. I need to start taking some of it back because there we go, there we go. That's how I had it earlier. That's what I was seeing. Yeah, of course the higher I turn the frequency on. Now if I leave that on those parts, because that's one of them, I'll just adjust in these. And I'll put the other. I'll put one of these back in. I want to see what happens to that. And that's what we've put in 88. Let's take this. Let's just move that off and just remember it was on the output. I just need a bit of light back to take that off of there. I'll put that back into that. Just in there because it actually does function now. I can't remember if we just tried that to see if... I'm just going to try on one of these. This one hasn't actually been in before by the looks of it because it's spread out there. Unless I just took it out at a weird angle and managed to explain the legs out. Just check that's the right way around and it is. There we go. So we've still not got the fly back connected. We're still at the same settings. I'll put the scope on. I just pressed the power button but the scope's not on. I'm going to go to that. It's just a leg of the resistor coming straight out of the output. I'm sure it's not touching anything. Let's go back to that. There you go. You see? Those ones from Blooming eBay are not very good at all when you compare them to that. There we go. What do we think about that? I'll try and get this to work better and show you if I can. I've taken this IRF840 out and I've got a IRF3205. Replaced the 3.3 ohm with a 220 ohm resistor. I've taken out the 10 ohm and I've put a 5.6 more on 10 ohms. I've put that in there. I'll carry it over in this small amount of time because it hasn't got a heatsink. There is a slight increase. I know that's not a great deal. But it is a little bit better. I'm progressing forward because I've put a ceramic capacitor in there. It's not as good as one of the film ones polyester jobbers. These green ones seem to like that the most. Even against one of these, it seems to be a slight difference. I prefer this. I don't know what I'm going to do. I'm going to take a small one of these to increase the frequency. That's what I need to try and do. Magic smoke.
