 Hey there YouTube Okay So I was having another little nose around the old internet and I'll come across a little circuit It's like a little microphone, you know a wireless transmitter and I suppose it could be like a considered a bug circuit FM transmitter I've got it connected this now Believe me, this is not the way you're supposed to set these up for the stuff that I read, but I really didn't think it was gonna work You know, I figured it's probably gonna be trial and error trial and error messing about and I'm surprised it actually it just works straight off the bat. So it's not brilliant my connections are absolutely terrible They're not sold This negative will just go the other side of this capacitor As this is like the the line capacitor not a little electric microphone electric Now all these are like real cheap parts from China passes everything I Didn't think it was actually gonna work very well because also these BC547 Transistor From what I've been reading is some of these transistors will work some of them won't but This does It's not brilliant It's the first one. It's not laid out on a better PCB the way it's supposed to be And there's lots of you know mess that can be picked up for all these wires the way they are from my understands, but It's my first little my first little FM Transmitter I built a kit And that worked so I was quite chopped about that. I think I just broke in this. I'm just pulling that wire off there I have you know easy enough to start it back up Yeah So like I said, I put a kit before and I think the kit came from the same fur as where this This came from the circuit this circuit Another one from talking electronics There's quite a few On the pages there the FM transmitters brilliant site to look at and It tells you all about the layout and everything and like I said well I built it like this this point-to-point because I figure well If someone's not right, or if I get it wrong Like I put a 2.2 nanofarad in rather than a 22 nanofarad Across here I didn't know stick when I was just looking at them once I'd soldered it in and I thought oh no, that's That's two to Basically was 22.2 nanofarads Is But one of my bags is marked up wrong anyway, it's marked up 22 nanofarads when it's 2.2 nanofarads Now if I'd have done that on a PCB that would be an all right pain in the backside for me to take out and I'd have you know just struggled with it, but doing it like this this point-to-point It does look a bit messier, but you do get to bend stuff around to where you need them and it's Quite easy to take something off or re-solder something like that that there as you can see it's come away So yeah, so let's have a little listen to it. Oh By the way, I haven't got a radio all I've got is you sold bit of board now The wires that I've chucked on there And Basically gives me a speaker out and a power in It doesn't have an aerial as such and it's quite terrible really. I use it I've got power on my little Little thing here And although that's making a lot of noise now when this is connecting on and the wires soldered But when that's come off it actually goes silent on that channel And then you can hear You can hear this this thing. I can adjust the frequency of the way it transmits by I want the frequency to be lower. I'll squeeze this coil together Six turns here. I Actually took that out of an old radio Did it come off this board? Yeah, it came off this board from just down in there There's loads on there so I'm going to do some some good playing around with these little bug Things and so with this my first one And it's it's not being picked up on the greatest piece of equipment, but it does get it there and Not as good as what you might hope but As far as I can make out. It's working. It's just like a little transmitter Not a very good one. It's my first one It does sound like there's a bit of sound coming out my speaker Which is good, but it'll be interesting to see whether that sound is Orderable or not. So I'm going to try it in the room now One two three four five one two three four five three four five One two three four five Hello testing testing as far as I can get away from that little radio But it seems to work Not brilliantly, but then I'm using very very cheap parts all of these parts I'm trying on and they're all very very cheap
