 There you guys here's a arm. I remember making one of these similar circuits while a while ago These ones are actually for wireless power So if I take them out of any of the color-coded these coils I'll put a battery between here and here That will come on this I will work wirelessly I'll try and make this so it's not easier Okay Right, what we got here Is the old familiar This is what they call the dual-frame I don't know if I can just take the scope off it for a second It's running at between 16 and 61 kHz What I did, I used the I've tried doing this before A little while ago I didn't get anywhere with it Only because I was thinking I was just making it more complicated and what it is I got myself a core out of an Xbox So I figured it would be pretty good It's quite magnetic as well I'm testing a lot my cores from the Ion Let's see how magnetic they are Anyway, I saw light because I wanted to go I made one of these This is pretty much my first circuit that I built How this works The light These came out of my thermostat control for the heating system That's why I know it's not good Because I've had to change them So I connect that one to the end of there And put this By that I don't know if you can see We have ourselves a bit of wireless electricity And it's basically like a dual feed Except this is just using this ring instead I can say that battery is pretty dead So that's pulling that out of there That's pretty good This one here This battery I'm not so sure about how dead or alive it is But it does give bad results It was just doing that for itself That's pretty good There we go So yeah And I've used the 2N2222 Because it's just a general purpose As you can see I've used these blue LEDs There's I have 6 of them Basically in parallel I think now I don't think you're supposed to do it like that It's just for this Just for this little All I wanted to do really was I've got a few more in I'm just going to stack them into this These come on as well I can put this up here Doesn't really matter on this board This project is Just building an infrared transmitter To see if any of my infrared perceivers work So I think we get into the Into its limit though Especially as the connection isn't so great Well they're pretty proud again Okay so the connection wasn't so great So we've got a 5, 6, 7, 8 8 LEDs Running from the 1 From the 1 battery there Not terribly bright but Certainly bright enough The camera's going to compensate Yeah so it's simple I'm quite chuffed with that There's my dual-fifth I'll draw a little circuit There we go That's been going for quite a while now I might just leave that See how long it goes Let's see what voltage is in the battery This bench has been tied twice today Back to the reasonable condition And twice It's been messed up again Let's put it on The tester while it's under load As well if I can Without disturbing it Can you see that? Yeah On DC Yeah Actually 1.29 Let's just take it out There for a second 1.34 So it's quite It's got quite a bit of charging in there It's really Maybe I should get that one That I know See how Let's try this We'll see what the voltage is on this first About there 1.16 1.7 But we're not going to bother With the last bits So I don't think that It's just going to Fit in and stay on By itself Because It's quite Can't get it to stay on Okay This isn't Just not going to play the game So If I can just get my hand out of the way There you go They're all quite bright too And that was with 1.1V, wasn't it? Yeah, that's pretty good Considering how many of these bulbs there are And Not going more, is it? That won't even light up The LED display On my Thermostat So that's 5608 That's 9 9 LEDs now Including that one That you can't see It's my hands in the way Down there Anyway Jullfeef Cheers guys
