 So I was reading this really interesting website and I was reading a section about trans sisters and how they can connect together one stage to another stage for like small amplifier circuits like this one. I built the circuit and it seems to work. I'm speaking to just a regular atome speaker and that is going into the capacitor into the base of the first transistor. That signal is amplified and passed to the emitter of the second transistor. But I'm not exactly sure that it actually starts like that because there's another way of looking at this. And that's that the load resistor on transistor one which I'll show you in a minute and I'll show you the circuit. But the load resistor on transistor one has evolved to go through. That is connected to the base of the second transistor and the load resistor is connected to the collector of the first transistor. But there's also a tap going to the base of the second transistor which then allows current to flow from the collector to through the emitter of the second transistor. There's a feedback resistor coming from the emitter of the second transistor which then feeds into the base of the first transistor. There's also a capacitor connected to the emitter to ground of the second transistor. And that acts as, well, like a shock absorber. But there's quite a high gain to go between these two transistors as there's no coupling capacitor. This is what they call direct coupling. And so having that capacitor there, it just keeps control over the gain. Because it takes time to charge and discharge. Now I don't know, I don't think that's the best overview of how this little circuit works. Because on the website it's described in much more detail and much better than what I just said. I'll show you the circuit. That's what I was speaking into. I don't know if you can see that's connected to the negative side of that 10-mic capacitor. And it's connected to the ground of the circuit. We've been powered at 6 volts from over there. And, well, I'm just going to show you how it's laid out there. I've just, like, put it out. And I'm going to show you the circuit on the webpage. This is another circuit from a fantastic... You know, if you want to get into learning electronics, this is a fantastic website. I'm getting so much information from here. And this is the circuit. The website is called TalkingElectronics.com. This belongs to a chap called Colin Mitchell. I would really advise you to all suggest that you should Google Colin Mitchell, TalkElectronics, and, you know, watch some videos that have been done with him and Davey off the EV blog. But, yeah. It's just a lamp circuit. But it works. Well, it seems to... It definitely does the job. A very small signal that's happening here as I'm talking. And this is moving. And the coil that's wrapped around this moves into the magnetic field. And, you know, it breaks up flux lines and causes a current. It's very small. Two millivolts peak-to-peak voltage, I should say. And then when it comes out of this side, as you can see on the scope, it's taken up three to four, but clipping on four of the... of the division boxes. The most division boxes. And now we're getting batteries low. That's brilliant, because that thing's been on for absolute hours. That's doing quite well. It's doing quite well, actually. I quite like this scope. Four hours of continuous use. Four hours to charge your backup again. Using, of course, the old batteries from the solar panel over there. The other one's gone. That went over the weekend. Oh, that's it. A nice little beep, though. Not a nasty, like you get on some of these things. But anyway, there you go. I just want to share a little circuit. It works. I'm going to give myself a thumbs up for that. I've got a lot to learn about these things. There is so much to learn. There's lots and lots of pages just about this and how this works. Lots and lots of pages, but... Yeah. I don't normally say this, but if you like, you know, if you like this sort of thing, from a complete novice, I'm a novice. I'm nearly one year in to this, so I'm an enthusiast. But if you like this sort of thing, give us a thumbs up, subscribe, and I'll try and put out at least one or two videos. Even though I know they're not very good, but they'll get better. That's all I can do, really. I'm hoping these get better. So, cheers for watching.
