 okay right so what I've done is I have just wired this into the output of the boost converter I also wanted to ensure that we had so you can see the voltage that's outputting from the boost converter rather than having to tune it up I'm here for blast to see what the voltage should be we got that as an output the same as what we had when the step-down converter was in line so we should now just be able to switch this on and the switch I've put the 2 amp fuse in here oh you saw that I showed you that and so we can see that we've got 20 volts coming out of the boost converter we've got 12.7 on the battery 20 volts from the boost converter 1.38 on there that's a bit of a way it's a bit of a before I start turning up I suppose it doesn't really matter like that because because the overhead lights over and it's not that dazzling so at the back we've got I think we're getting to the limit are we no 10 million I think this yeah 10 million up there we go so I'm probably gonna get to that's it I can't go any higher on the that's just not turning on this doing that so what we got we're 80 million put the back 30 million the boost converter and 10 million here but the beauty about this one it's silent and there's none of that washing machine fan going not that wash machine's got fans in them but you don't mean fan in the power supply that so no easy bugger in it compared to this we can we just see we can turn up the current a little bit and there we go on 17 and a half volts 44 million of course all I'm gonna do now turn that up to have more is to turn up the boost converter well basically this by itself you're to get about like eight and a half volts out of it going directly to the battery sorry about the camera so I think that should probably turn this just current limit this to 40 million well that's we jump 28 to 42 no that's not as not as gentle as our life I think and maybe because that the voltage is up but that's not as gentle as I'd like on the current I don't know that's an issue and do pretty gentle there too but look at that skip from 29 to 41 that's a that's a thing isn't it that's a thing well let's turn the volume down at what I volume I mean the voltage let's see we just get a grip about using the voltage okay so 29 I want to see 30 million that's what I want to see so in between the current let's just stand on okay 30 31 okay so we do have control like that so I turn that down now pretty much all the way off if I turn this up to let's say 30 volts input I'm gonna put on 35 which I think I'm 35 I'll do 30 30 okay 30 volts input again here's a point I think that's probably coming from this probably from this display not how many it's like just a little bit listen should probably do a heat test and the reason why that's not really doing a great job suppose is because I've got the I've got the current set all the way to off let's just turn it up a little bit and turn it up a little bit now that will be current full blast so I could just turn it up at least we're getting that range now I'm not just jumping straight into the 40 because that was a little bit worrying I'm not quite sure what the limit is I can push that LED to I'm pretty sure it's gonna be with a hundred millionths so at the back there look we've got 30 millionth and on the 30 30 volt output that's as much as what we're getting but that's because this is restricted not because it you know hard draw more load 30 millionth at the back let's just pop this off here just a little feel of the resistors because I wouldn't really expect to mature there's a little high pitch noise yeah little high pitch noise I'm quite sure that's all about yeah so I do have a variable power line so desire and I could probably turn up a little bit louder because I know I can turn this boost booster up to 35 volts I'm pretty I think it's 35 volts I think the caps are 35 volts so that's gonna be its limit as you can see that's going up there so that's just I just wanted 30 volts on there not that I'd keep this like this because of them they're gonna do low voltage things we're doing something like you know five volts I'm gonna have this thing on like eight volts or something the minimal for me to do the work here of it the control there there you go run for my battery well chuffed and yeah it sounds kind of warm probably this is quite right cheers watching guys
