 Hey there Okay, I've lost the camera Right, so today Today I was really hoping I'd get some post and I did get some post That's good. Let me shift this off the other way And in here We got some Couple of LM 1875s, which are the genuine article which I've already looked and they look exactly the same as the piece of one from China But these are The one for China supposed to be rip off apparently and these are the genuine articles. So I got I got five. I had to buy five Otherwise I'd have to pay a couple of pounds just for one Never mind, and I got some 337s Which is basically a variable negative Regulator Which is good because On my power supply that I built I've taken it apart again because it was good enough for there for that single one but now I need a 24 volts negative and positive. I didn't want to buy a 24 volts Negative regulator because I'd have had to buy 50 of them or a really heavy price for just one So I thought I'd get these variable ones and I would just use some resistors and get it 24 volts Unlocking 24 volts. I've already done it with a 317 there That's that 24 volts already, and I've already set up ready for this This three one is 337 nearly there's a couple more components. I need to put in there But it's nearly done and then I will build These two again and the reason why I've got to do them again is because I need this This board and I can build them both onto this board because it's got a gap which means that these rails are separated I'm here There it's not got the gap and so the rails go along along there until I can't build two onto the same board I can do it here, but while I've While I was waiting for them, I thought I'd just build another little amplifier And this is two transistors and you can actually use a speaker as a microphone And I've got that connected up to the This is really annoyed me and I've made a video about how annoying this can be But no one's different thing and I've connected the speaker up to it And I connected it to this little amplifier that I built using the LM386, but this is a kit one And it doesn't fare as well as some of the Some of the better LM386 op amp chips that I got And everyone's But I'm gonna put this here. Oh, and I'm just gonna do a little hello. Can you hear that? It's connected through that speaker so I can go low one two one two and you can see it there because that's why you're biased So there's goes not for all that other rubbish stuff, but to watch yourself talk. Hello one two And you can hear yourself talk out of there, which is really cool And we haven't got that much feedback, but it is a little bit I'm not sure how well the speaker is supposed to do as a microphone And just to answer a question that I was asked today About which kit would I say is best I put down the LEDs, but the LED lamps, but I don't think that's the case I think That clock over there in the background it's great and Even though I got it on the most boring setting really for the for the second hand and it does do some funky stuff It's still a pretty damn good clock. I don't think I could actually live without it now I couldn't live without it if you know what I mean, but I would really really be I really like it God damn these speakers got some stuff on them when I breathe by is trying to kill me It's not very good Yeah, we'll get over that microphone too many microphones in one space think But I suppose you can still hear me on me at the microphone But yeah, nice little amplifier circuit there, so I'm gonna pull this apart now and I'm build And build two of those and get them on again and get some music rocking and rolling Oh, I'm a bit cheeky. I need to add I've got this little amplifier circuit From the talking electronics website Colin Mitchell brilliant site to go to and learn lots and lots of stuff Here it is. Oh Stop the feedback. Yep. So there you go. I thought well, that's the right thing to do is have that Give the money's recognition loads and loads of Circuits on there. It's a great place to find little circuits to sit and practice
