 Hey YouTube, I just thought I'd show this. There's a little circuit here, a couple of components that I've never used before First component that I've not used before This little tiny double diode thing, it's called a diac. You can see that This one here Which is a triac this is a Basically, I don't know where it is now, but I bought a dimmer AC dimmer switch for a light off eBay and it didn't function at all Now look inside it. It didn't look that complicated. So I thought well, I'll go and have a look for any AC dimmer Circuits And I found one. I found a few actually But this is the one that I looked at now Some of the components on here are different to the one that was on the original circuit because I didn't have those components The diac is different to the original circuit and the triac is different to the original circuit. Also, I haven't got a A 0.027 micro farad or 27 LAN farad Well, I think it's got to be line voltage across that's about 300 330 volt or something I haven't I haven't got one of those. I did have a 600 volt. I think it's 400 volt Sorry, we're looking we're not looking there. So if you're looking here, yeah There's a 400 volt there capacitor And I've got it connected because these are dangerous circuits, of course, I know that But I've sort of limited it. It's not I can still get killed off this But I have, you know, limited it down quite a bit and I should probably have a safety fuse as well But from what I understand fuses are there to protect the equipment not so much as start you from killing Part of the circuit The best one that can stop that from happening. I think is me. So what I've done is I've um Here's my mains And here's a 240 volts to 12 volt transformer It's a brown the same sort of structure and everything pretty much the same as this and this is a 20 v8 at 12 volts And I've backed the back top. So 240 volts going in 12 volts coming out 12 volts going in 240 volts coming out and it's limited by the by the coils themselves So I can get about 120 milliamps Maybe a little bit more at 250 volts with this so that it can still kill me most definitely But it does put a little bit of a um A little bit of a break on On this circuit. So And I use this which has got a um An rcd connected to it even though to be fair if I make myself part of the circuit And that rcd is not going to make any difference. Also, I've overseen me as a load and carry on and produce Allowing the power So there you go. I just heard it just click off then As it did because the connections here Yeah, not so great. I need to just perfect that Hold on look at the bulb All right, just switch it. I can't really set it for power. So we go so As you can see Lights up if I give it Full brightness that's as much as my power supplies these transformers were allowed through That's a 40 watts bulb That's how you do in part of the job. I know you can see the The dimmer part of it. It's nice We need to remember That this is a live circuit And I need to be very very careful about anything that I touch here I have made sure that there's um that this Chassis to this is not live to the triac. It's not Um, but I'm not gonna stick with my fingers on it And there's no live On the casing here But I've put a knob on there just in case Because even though I've already done these checks that they're isolated I don't trust it. I don't trust case something happens. I don't even like putting my fingers anywhere near the socket board now but It shows it working and it does the With full line voltage through of course, I'd have a lot more movement on the On the on the variation of it because it would be a lot brighter now and I'll have to turn it down a lot more Um to get it to go off There we go. That's my first one. I will be adding the um This other capacitor and resistor because that will just help Um, not in the stand any sort of signal noise or Basically any noise is going through the the system and I hope just wash that out to nothing That's my very first triac circuit I'm quite pleased that I managed to do something again practical of how I like doing Something that can actually be used That I could use I could connect that to my a a I wonder if it will work with one of my inverters DC to AC inverters Hmm Anyway, just very quickly. So you um that it works on Straight to the main supply so you can plug it out. So I shouldn't really do them like this, but Just for the sake of this that's not going to be a problem. I'll fix you I've changed the the part and I've put a 250k in It must remember this is all live If nothing but the the fuse inside the plug Any type of protection And we're getting now 40 watts Because it's only a 40 watt. Oh Thanks for watching
