 okay right we've got another one of these little inverter circuits now I did start building one I did build one with the CD40 47 I can't remember how well I managed to kill it I managed to kill it I had it working I brought some footage and it was all good and I was changing over lots of different different MOSFETs and transistors so I could show you this is the circuit for this if I pop this back in here I actually got to do a quick change tomorrow I've got some got some of these on their way I ordered them the day before yesterday so I'm hoping they'll be here tomorrow because that's supposed to be next day delivery so and that will go back in there and that made this circuit working which is the 4047 so I figured okay well I got some 4017s because they came with the the little kits to make the infrared switches you know and so I've popped one of those in down here and I'm pulsing that from the output of the 555 timer and that's given me two outputs now the difference between this and the 4047 is the 4047 gives you a non-inverting and inverting output square but this one gives you this but it works I don't think it's as good now on this circuit really to feed my transformer then you need 12 volts and I should have put a voltage regulator in and brought 12 volts in regulated down for 9 volts because this seems to be happier in 9 volt range but what I've done is I've cheated I couldn't I couldn't be bothered to why one up on here I should do really because I'm doing it for experience not you know trying to take the lazy man's way out of doing things but what I ended up doing was just making it another connection to the power supply over there to I hit that and gets gets bright because we've got we've got 12 and a half volts I'm trying to simulate my batteries 25 volts but yeah so that's been turning it all off I wasn't supposed to do that I supposed to put you on and you see there's a little bit of a weirdness going on that way it's like flicker on the on the bulb which you don't normally get with the with you the 555 circuit that I did you didn't get that flicker and with the 4047 circuit you didn't get that flicker just for this circuit here on my diagram here it has the 9 volt regulator I can't remember where I found this where I found this circuit if anybody wants to point it out to me I don't as you can see look it isn't I've not written anything on the paper but that works I made a couple of changes I put there was a 33k there I put a 27k in to get the 50 hertz and it's 10 volts 010 volts on the transformer I've already got 9 volts and 12 so I think that's the distance made here to get the output I'm not sure that's actually correct but I've got 12 volts and one anyway yeah just another basic simple inverter now again the same as with the 4047 you can't these are just like lights you know a lot of the places that I find these circuits on the internet and they're normally from like India type areas Philippines those sort of places and when I see them using them on the videos it's normally it's normally those sort of areas again because they're using their motorbike batteries to have a bit of power in the house so but just for practice wiring up I'm getting a lot quicker at doing this sort of thing I remember it used to be a right headache an hour or so just the wire up a 555 but it seems to be just putting these to the other quite quickly now so I am going to make the H bridge with this that's what I was going to go on and do was make a H bridge inverter and that's what I will do when I got the the other chip tomorrow so there'll be a video coming out about for cd 4047 H bridge I should probably add actually that this the outputs of this chip into these resistors and these are jumping across these MOSFETs I've just left it all the same wired up you know ready for this circuit to go back and I've just really been lazy and so I've just jumped onto those MOSFETs that are already there with the wires and everything and grounded and I just added a couple of resistors to the ground here which is illustrated everything's on here anyway everything's on the circuit and on these I've used the IRF 30 3205s because they're just pretty good all around as I think
