 What we got here is my controller for my Hobson, Hobson X4H501S quadcopter or drone. Now this is great, I love the quadcopter. Much better now I've got this firmware update. Now somebody may think, oh what's these for? Well these are for two things, one so I don't actually be resting on them while I'm doing this. And I do have a little bit of extra here just to help me out with that. And two, it's my answer to, if I'm in follow me mode and I want to chuck this in my backpack, how can I do that? Well I can put these on. But today when I took it out today and I put it into, oh I think it was in return to home. So it doesn't work, as far as I like to work out it switched these off in return to home. That's good, but in follow me mode it doesn't, you can still use these. But if you put these on, it sort of like stops the movement of them. And if you put an elastic band across, that will do it even better. And then you can just chuck it into the back of your backpack. I'm going to put this into the netted part of the exterior part of my backpack on the back. And then see if I get a good follow me mode. But I'm going to go into an open field to do it. Because this doesn't like doing that follow me mode when you're running in and around trees. It's not really good for your quadcopter because it's blind. It may have the camera, but it can't negotiate around things. So, but the thing with these of course is they get through the batteries really quickly. And although, you know, I've got no problems with charging up the rechargeable batteries that I've got. The problem is some of my rechargeable batteries now are starting to show signs of age. Because I've had them for quite a few years. Quite a few years and some of them, you know, they're just not charging. They're not holding a charge for five minutes and it's not going to talk. I've also needed something else as well. I've got two, I've got three pencil battery chargers. All the same company, Energizer. Two of them are exactly the same and we bought exactly the same time. And they're exactly the same output, so everything else. But if I am to put them into a like kilowatt meter, one of them shows six watts. Well between sort of like, let's say between four point three and five watts. And it's supposed to really be six watts. And the other one shows less than that. It shows maximum of like four point one, four point two. So you know they're exactly the same. There's a big difference in the output. I mean that's like 20% area. So I've already been in the back of this. I'm not going to lie. I've already been in the back. Why can't I get in the back? What am I missing? Am I missing? No, I'm not. This is fine. There's a lot of things, right? I've already been in the back. And I've done some modifications. My modifications, even though it's not easy to see straight away, is this will just come straight out. That's there because these things that were in here, I've taken out is like spacing type things. And also all this was built up to here and I've cut it all out. All gone. The reason behind that is because I want to be able to fit these in. And now they do. Two pair of these go in here quite nicely. And which means I have the ability to balance charge. Yeah, without taking them out. And here's the other balance charge. I've got two charges. So I can do this with two individual charges. But what I'm going to do is I'm going to attach these. I've got two pair. Oh, sorry. I've got one pair made up already. And they're going to attach basically here. Which means I can connect them and disconnect them. And I can do all that pretty much from just taking the battery pack cover off by having these underneath the back cover. And having these underneath the back cover so I can disconnect these. I can charge them when nothing is charging. Reconnect. But also I want to be able to use because if something goes wrong with those batteries, I want to be able to just quickly take the back off four screws just as quickly as that was and put this in. Disconnect these of course nice and easy from the plugs and put this in. So what I'm going to do as well is I'm going to connect onto this. This. Which fits into, of course, these. So I can just interchange these batteries. Nice and simple. And I've done most of the work, like I said. I've cut all of this out. And I know that these fit because I've already done it. I've already put the back on and put the cover on and had the wires there so I could get to them. And I really know that. And now I'm going to, I'm going to desolder this because this is going to actually be in operation today. I've already been out. And I've used these batteries that are on charge over there. And by the time I've set this up to have this fitted it means that I can just literally take these out the back put this back in with the recharge batteries. Of course that would just plug straight into the socket so I'm about soldering. Just into one it doesn't matter. They're just in parallel. And then when of course these plug in, both of these will plug in because they'll be in parallel as well. And we're good to get. We're good to fly. And then I'll be able to do time checks, measurement checks on how long it takes for these to run out against how long it takes these ones to run out. And just more things to be fapping them out with. It's all good fun. So that's what we're going to do now. So there we go. We've got 0.5 of an amp. Okay, 0.58 of an amp. So that's quite a bit of a pump. And we haven't even got the quadcopter on. So I'm just going to put that there and just let the rest of it run out and everything else goes through. Okay. So hopefully in a second that's going to be talking to that quadcopter. Yep. Okay. Now I want to wait for it to start collecting the satellites. It's going to take a couple of few minutes because I'm indoors and I don't want to keep turning this over for fear of breaking the connection and start again. So we'll just give it a couple of minutes to get some idea. But even half an amp, over half an amp that's drawing out these batteries. And that's quite a bit of power, really. Quite a bit of power. Yeah, let's just give it a little bit more time. Look at what's going on over there. Right, on the quad itself it wants me to calibrate it for starters. But we've got five on the quad and zero on the handset. Man, I've got three on the handset. Three on the handset. Seven on the quad, three on the handset. I'm going to turn it around so you can have a look. I hope you can see that because I can't really see what you can see. Try and turn it the best I can. And it looks like we're in return home now to be in return now. So I've got four on the handset and seven on the quad. And it's still going up in power. It's using more power. Seven on the quad, five on the handset. And this is without record or anything like that. I don't actually think there's a chip in it. No chip. You can see that. You can get the angle. I'm sorry if I can't. I just have to sort of trust me a little bit. I'm going to wait until it's 12 on both so we get to see the sort of power this is using. I'll be very conscious so I've got the live connection in my hand and I don't want it to touch the case of the GPS. I don't want it to touch anything apart from the way it is. Okay, we've got eight on the quad, six on the GPS, six on the handset. And we're still going up in power. Still using more current, but more and more. Seven on the handset, eight on the quad. And we're still going up. So we're just going to just put my hand for a second. Just put like that. Just make sure that you're thinking of touching anything. So we're still going up in power. And I want to just do the calibration. Okay, that's one part of the calibration. I know it's going to ask you for calibration, so I'm doing that now. Okay, so now we're in the ability of flight. And now we're going to very carefully put this over. And I've got two on the handset, nine on the quad. Can you see that? Maybe you can see. So I've got the handset and eleven on the quad now. So we can probably safely assume them. Now this is with nothing else. This is, I haven't got a chip in the quad. I would have to turn this off again. And then again, if I turn it off, it would be very quick for this to come back. And then put a chip in and press record. If I press record, it's just going to see any difference. So it's not going to record. And it would actually be the quad doing the work. This is just going to send the signal momentarily. So really, I suppose I don't need to worry about that too much. I'm going to be turning the quad on while I've got it set up like this anyway. So we can say then so in sort of like 0.62 I've sort of got 0.6245 a second ago. There we went 0.58. In retrospect, if I put on the not hold side, we'll get an idea of the highest and the average. Can you see that what's going on behind there? I'm really sorry. I'll tell you later. It's just, I'm going to give you that and I'm hoping that I can, I don't want to have to set the board out. I'm hoping I can literally just solder to here. This is great because it says 4V to 13V that you can put into this. I don't know if you can see that, I hope you can. 4V to 13V. So these being around about 8.4V are what they are now because they're fully charged is within that 6V range. And I can just parallel them up. I have seen somebody else do something like this and they've got a book converting all sorts to keep that 6V. You know, 6V is the way I look at it is this is going to require the same amount of power. So if you put 6V in it's going to require more current. If you put 8V in it's going to require less current. At least that's the way my brain tries to tell me it works. So I'm going to go along with this here. It's all in the middle of the range. Hopefully I'm going to get extended battery control times. If I don't, this whole thing has been wasted time. But I don't think that's going to work out like that. I'm pretty confident it's going to work out the way I think it's going to work out. So I'm going to solder those onto there. I'm going to solder this onto here. And that's it. We're done because I've done everything else already. I've done that. I've videoed it. I did the whole thing on video. Now I did it all. So if you do want to see all of that I'll do it. I can put that up. But I'm not going to water everybody with the labors of it. It's quite simple really. But we just want to see it in action. And the ability of course to put these in and to disconnect them while they're in and to charge them. Disconnect the charges and reconnect them. We're good. I was going to do some switches. I've got some switches and plugs socket and stuff. And I thought I'm making a lot of work for myself. I don't need to do it like that. And so what happens if I knock the switch while I'm using it. And I'll cut out on power. It's going to come back home to me isn't it? Which is pretty good. But let's just get on and do this. I've got more of these things spare. All taken from another helicopter that I flew into trees a couple of years ago. I was trying to see if I could fly a helicopter that only had one pedder on top. Guess what? At that time I couldn't. At this time I don't know if I can either. So I can't bother with them anymore. I've got another one. I bought two and one for spares. Just in case I smashed one up. I did smash one up. It was so easily done to smash it up. I didn't bother using it. It was for spares so I'm probably going to put that flogging it up as well. I don't even flog it. I'll take a big tree branch to it and start hitting it and sell it. I'll speed through this bit because we're going to wait now two minutes for the thing to use up. Unless it's something interesting I can tell you. I don't think I'll get anything interesting to say. I've just got something in the post. Hold on. Okay. There's going to be something in the post today. There's something. Hello. It's Christmas. Oh, brilliant. Transistors. Transistors. These, if I remember, are complimentary two, two, two, two, two, two, two. I can't get it open. Yes. Ten of each. Ten of each. I shall get in ten at a later date. I just panted some of these. I saw a couple of few circuits I wanted to build that use complimentary pairs with two end two, two, two, two. But they're in this these like older style metal cases. And I thought, oh, they're nice and cheap. I'll get some though. Apparently guaranteed to be original, excuse me, genuine. And I'll make a little project look quite nice. That was in the post today. The post today. The post today. Solder on just now. I could just splice this, I know. But I'm not going to. If I can actually get the lamp thing out. Do you know what I'm going to do? I'm going to cut some. Because I can see I'm probably going to mess trying to get that result. I'm just going to cut them. I'm going to cut them so they're actually usable still. Okay. I'm going to take this up here. I'm going to take that off there. And do the first part of the modification. I'm going to be with this little baby. Because what we want is we want this on here. Like so. So I've got two nice bits of solder there. So let's get these soldered on here. Because this means I can just connect this in at any stage. So the two other plugs. See what I'm doing. So there we go. So now that's going to be nice and easily to connecting to these two and to these two sockets. That plug. Into these two sockets that's going to get here. And I'm debating whether just to spice, whether just to trim this wire back here and just literally go to here. Or to try and go on to the solder joint. I'm just wondering what might be to my benefit. I think I'm going to try and go on to the solder joint itself. And if I can't I'll put two nice bits of solder on there. So I'm just going to go on to these ones. That's I think is going to be the situation. What's going on with this solder? It's like trying to tell it's a half way mark or something. Because it's tied up. Oh that's a bit annoying. I can't just unroll it. So it's the way that they put it on at the the facatory. What's going on here? That is annoying. I'd like to be able to just unroll. Oh it's dead again. I know it's not very good for you to breathe this stuff in but it does smell nice. I certainly shouldn't be breathing it in like that. But I've got to I need to buy some carbon filter and just set myself up with a smaller extractor fan. Because the one I've got is way too big. Way too over the top. It gets in the way now. And I'm using the phone stand. I've got a non-rechargable battery on charge. I just need to keep going on that. That's all I've got. It's only a milliamp. It's at 9.1 volts at the moment. Okay. They look like they've got enough solder on them. I'm going to stick a bit more solder on these joints here. Just to make sure there's plenty. I'll just clean that. There we go. Beautiful clean tip. Now in the other video I've shown how this takes around about 630 milliamps while it's running when it's got 12 GPS's and all that sort of stuff on the go. Okay. It might be worth me either editing part out of that video and splicing into this one or actually putting that video up as well. And having this as the quick see how it's done and the other one as the in-depth cutting through these bits and all that sort of stuff. We'll see. I just hope that now reaches. This is the case. This is going to be on the side just inside the case there. Brightly. I may have to cut the top of this out. Well that's fine if I do. Lovely. You don't want any sort of cloudy connections or anything. That's nice. Okay. If I just push those wires out of the way they're not going to be interfering with anything or each other. Which is the main thing. We don't want any short circuits. They look nice and substantial enough to do the job. Well what we've got to do really I suppose is plug one of these in and kiss goodbye to my transceiver. I say transceiver because we've got information that comes back from the quad to the display here. So it's transmitting and receiving. So transceiver. He's up all the soldering I've got to do. Is that really it? Oh I don't at all. Oh really? I can turn this thing off. I can turn it off. I can read in my tip to make sure that stays beautiful. Generally you end up doing little jobs like this. You end up putting more solder back on the tip. Just to ensure you keep it looking nice. Keep it looking nice. Just keep it performing nice. I've got no idea what's going on here. It's all in a mess and a tangling. A bit of a knock going on there. Oh my knife knife's all gone. Really scary. It's like pattern on the soldering. I've got another reel of that as well. I've got it sent to me free of charge. So now when I put these this in, I can literally just put this in here and that will fit back in the way it was because of those cutouts already there for the loops of course. And then all I'm going to do is connect up this. Maybe not that way, but that way. And I have that connected to four pencil patches. Not a problem. I'm not using the pencil patches. I should now be able to just put one of these in. Or two. Because they're paralleled. Gotta double check these connections again. Just because this is it and that way it's coming on to you. Oh, why am I starting to sweat? Oh, would you believe it? I'm doing it the wrong way round. Good job that didn't work. And that just means that the actual wires are the correct way round. This is the moment of truth. That's just one on there. It's just going to be a parallel connection for the other one. And there we go. Full kick your ass battery. I've not had that before when I put the pencil batteries in there. Because that is like 8 volts, that's 8.4 volts. Loads of power. So, there we go. Now, I'm just going to take that out and fit these two batteries. That is quite annoying and deeper. Fit these two batteries like this. As it's going to be these that I'll have in now. Test everything out. I probably should try and do that like that. Because, well, I don't need to. Because even though the wires are plenty long enough I really do need the wires out of the way. I decided the other day that I was going to feed that down there because this will connect. As long as I can get these from, I don't mind undoing the back. But wouldn't it just be nice and convenient if I could do it all from the back of the panel just by sliding off the back there. And there is some space but I think what I'm going to have to do is I can't work out which way is going to be best. Because I didn't have these on when I checked it before. So there could be a little bit of a a little bit of a disagreement with what I'm actually saying. But it did work before just having the actual connection terminals and the charge and ones there and I could access them all from the back but I hadn't got these sold into place. So couldn't honestly say how that's going to be now. But regardless it's four screws and if it's, yeah, if I'm just like my little Simon thing the second time I'm changing the motor I don't even put the other point in the screws back in. Where's the point? If I keep crashing it, I look around and it just starts to come apart. I just clip it back together again and just come and fly. How lazy am I? But the reason why, because I don't want to be charging these with it connected because, okay there's a possibility I could but it's the balancing then between these they'd normally be another sense wire type thing going on and I'm not 100% proficient on what it is I'm saying right now. So please don't condemn me for not getting this exactly right. So I'm not going to try and preach anything all I'm trying to say is that I feel more comfortable disconnecting these when I'm charging because I don't believe that I can just leave them connected because these two circuits then are connected in parallel while I'm charging with two different charges and there's no sense between to make sure they both get charged equally it could be that just having them connected might mean that they try to balance themselves out equally but I don't know enough to say that's going to happen. That's why I've gone to the thinking of disconnecting whenever I do it. If anybody out there has got a chance to do it and you've got enough experience whatever to back that up then great I'd love to hear from you but apart from that I'm going to do it this way because I believe that I'm on to a more of a winner doing it like this. And as of all I've done is just put these in power. I'm pretty comfortable but I shouldn't have any fires or maybe I should leave that for a few minutes just no because everything I've sort of understand is that this should be okay. And as you can see look my little that's the wrong one isn't it? I've just got a little stick out here this is how I want it because this will move in oh that's not good I'm actually going to wire come out the thing there but this is what I thought might be easy for me to be able to do and then there I it doesn't matter which one goes into which charge because they're both the same two cell lipo 800 mA charges nothing that's getting warm is it? just my hands I'm setting a little bit because I'm nervous I'm getting this right and now this is going to be the thing can I actually put this on the back and have it all be in there and it's probably going to be a case of no you can't and you're right no there is a little bit of a a little bit of a thing but it's just all that means I've got another one out the way a little bit more or think of another way of putting these in to have it easier to access because if that's down there like that the rest of it is going to be okay the rest of it will be okay but if I had to take the back off to do it I might as well just took all the wires out of the way and not have that headache at all about trying to squeeze everything in because that should be okay let's see what I'm doing that should be okay so maybe that's what I'm going to do then so this is where I was thinking about putting the switches in to switch these batteries apart from each other not disconnect them maybe from the system but just switch them away from each other so I would just have a switch to disconnect the two batteries from being in parallel and that's it so hopefully there I shouldn't really have any issues because that seems okay again then if I screw it all back down that's good we still got plenty of any extra power so I was just thinking about putting the toggle switch up here so I've got two batteries on or one battery which then when I charge them both I'm going to switch on to one battery so I've got two separate chargers but of course I'd have to do that with proper isolation positive and negative disconnected from each other and that's the way I'd be wanting to do it so if anyone's had any suggestions on that I'd really be chuffed to hear from you and that's it I'm going to call that a bit of a win a little win I'm not saying I've not seen that even when I put it in there but then again my Jura sub batteries I think are a little bit depleted anyway I've been putting it on full blast before so that'd be first little modification I'm still waiting for the antennas to come through so I've got my distance for the visual and also for the range I took it up over 200 meters today and it's got some great footage great footage unfortunately after 12 minutes I forgot to clear off the stuff that was on the 4th gear drive and after 12 minutes sort of 37 or something it sort of switched off the recording I only know that because when I played it back here of course it tells me on the player how long the time is and I had loads of fun with it afterwards plenty of time so I still yesterday I had a 22 minutes flight out of it but I wasn't doing any recording so I was really chuffed with that because I had my phone out there with me I did the timer and unfortunately what seemed to have happened was I did a cut and paste from the 4th gear car to put it onto my computer drive and I made a new folder for it drone flights put it into that and went back to the actual drive to watch it and it was there not a problem did some other things, rebooted went back to the drive and I couldn't find the folder let alone the files the video files so I don't know what's happened there I don't know what's happened because I've got some great scenery great scenery because there's no wind no winds today, at least there wasn't I'm looking out of the trees now and they're blowing around a little bit but still no winds and I was well chuffed, of course I've got the screws in I'm not so losing looking around there so that's it guys, that's it for the first bit of modification I've got the extra power I've got extra voltage just a little bit I need a couple of volts above what you get from this I've still got the capability of just plugging this in with batteries so it is a case of just these 4 screws and to be completely honest with you it's not as low it's lots of screwing to the miter it's only a few turns and they sort of tighten up so I know me because I don't intend on throwing this thing around you can just put 2 screws in but I'll do the 4 screws because I'm not lazy today I've got that nipped down done that's nipped down type I've just heard one of the screws that I could hear rattling around in there just like I'm laying on the floor so maybe I won't be putting all 4 in there but I'm not right this minute anyway I'll have to have a little scoot around for that but I'll do that on the end time what I've got in that corner that one in the top corner but I will find you the ones and I will put them in I thought there was another one left in here but I must have chucked them both on oh yeah there is one left in here so let's do that again nice and quick look and full thing on the battery great stuff I just got to wait another about 7 hours now for this thing to charge I put it on I wrote it down over there there's no smoke I think it was 11.05 when I put it on to charge so it would be interesting to see because I've complained to the seller I've complained to the seller because this thing has taken about 6.5 hours nearly 7 hours to charge which means that the 800mA output of that charger which I know is that 800mA because look it wants 12 volt input of 800mA output and that's all it's drawing ok now when you buy these and you get the 800mA from pubsum hopefully you're better focusing on that but that says 800mA 0.8 amp output here they advertise on theirs now this never worked for me because they gave me a 120 volt adapter ok to plug into this well now I should have had a 240 volt adapter really it was being where I live and I didn't check it because because I just didn't think I'd have to honestly so but I was really hoping that the advertised time for charging those batteries which I think it's supposed to be like just under 3 hours is because you're using 800mA now I could I could connect it to my power supply I could connect it to that I could set up to 800mA put it into my volt and just directly connect but I wanted to try and keep the battery as good as possible for as long as possible so it's taking so long but pubsum have said that they're going to give me they're really confused with how they're going to do it they're going to send me out another one of these which they haven't got until the 7th of July which is fine or they're going to give me $30 in credit into my gear best wallet so I'm going to exchange it down that 5 5 credits type thing per dollar you have to get 50 you have to buy enough to get 50 of these credit points to get $1 but they want to exchange rate with me for $5 for $1 for my $30 refund oh I'm one for doing the figures so I don't like the idea of that because that means I get like less than $2.5 quid and these cost more than that to buy here or from there so I prefer to have another one of these things because if anything goes wrong at least you've got another backup I'll have 3 working ones which is great plus the iMacs anyway I'm on the shuttle success on the battery upgrade I was going to try and use these types of batteries but they just bloody won't fit in but I'd have time going across the top of the GPS I didn't really want to have that metal type stuff going across the top of the GPS so that's what I'm hoping is going to work out quite well I will do time checks on one recharge of these two and we'll see how that works out each pack by the way is 1100mAh so I've got 2200mAh on the 8.4 volts which will work out of course well one of these is 2200mAh but it's only 3.7 volts next upgrade antennas catch you later guys thanks for watching
