1
00:00:00,000 --> 00:00:06,620
I can in theory wait longer yeah, it's just like it yeah, we need it like yesterday

2
00:00:06,620 --> 00:00:12,120
And I was planning to get it ready for Friday, but apparently we need to test this thing before Friday

3
00:00:12,120 --> 00:00:14,120
And I kind of don't want to test it

4
00:00:16,600 --> 00:00:22,320
Everything is fine. Yeah, nothing's broken. We're trained professionals. We're just trying to call the computer with

5
00:00:23,640 --> 00:00:27,600
This thing so what exactly is happening here? Oh, you want to see?

6
00:00:30,120 --> 00:00:35,060
Okay, let me show you so this is what I've been planning for the last a little bit. This is the fan

7
00:00:35,680 --> 00:00:38,180
This is a 3d printed shroud. We're just about to get

8
00:00:42,240 --> 00:00:48,040
This box that I didn't bother modeling very well, that's a Corsair 5000 X case

9
00:00:49,400 --> 00:00:53,940
So you're gonna mount we're gonna mount a big ass fan that big ass fan

10
00:00:54,200 --> 00:00:58,200
we're gonna put a shroud between the fan and computer and

11
00:00:58,800 --> 00:01:03,520
And we're about to make This computer like go to non here

12
00:01:04,360 --> 00:01:13,400
22.8,000 CFM So for context the highest airflow PC that we had that literally blew the top of the case off was about 4,000

13
00:01:14,400 --> 00:01:17,440
So this is five times. Yeah, it's basically five times

14
00:01:18,000 --> 00:01:22,840
So yeah, this is meant for like a big ass RC thing. Yeah, this has

15
00:01:23,640 --> 00:01:30,120
58 kilograms of thrust two of them you can lift yourself up off the ground if you weigh less than a hundred and yeah

16
00:01:30,480 --> 00:01:34,740
Seven kgs. What's that in pounds? I don't know what that is in freedom units

17
00:01:36,160 --> 00:01:39,440
There you go. Someone has worked in freedom units the whole life

18
00:01:40,720 --> 00:01:46,540
Yeah, that's what we're doing Alex and I discussed at length how we're gonna power this thing, okay?

19
00:01:47,040 --> 00:01:51,920
The amount of power needed to make this thing spin 60 horsepower

20
00:01:51,920 --> 00:01:55,440
Okay, to put that in perspective, that's half the power of my car

21
00:01:57,080 --> 00:01:59,920
So legitimately this was the discussion, okay?

22
00:02:00,960 --> 00:02:06,060
number one Buy a whole bunch of lipo batteries and put them in series

23
00:02:06,560 --> 00:02:10,300
uh-huh, or buy a volt battery like from a car

24
00:02:11,080 --> 00:02:19,680
cut it in half figuratively, but just like remove a bunch of cells until we got the right voltage because a volt battery can provide like

25
00:02:20,520 --> 00:02:29,680
600 amp of current from its cell pack So we just we remove a whole bunch of cells until we get the hundred volts needed to power this thing and we literally have a car

26
00:02:29,680 --> 00:02:32,200
Battery sitting here. It'll be about this big

27
00:02:33,200 --> 00:02:37,840
That that need to be water cooled by the way because the volt battery is water cooled

28
00:02:39,280 --> 00:02:42,560
Because it's one of the best batteries ever made and that would power this thing

29
00:02:42,680 --> 00:02:46,800
We ended up going with lipo batteries because it was slightly cheaper at like

30
00:02:47,600 --> 00:02:50,800
foreground Yeah, something like that

31
00:02:50,800 --> 00:02:56,640
now You might be wondering why did we not connect it to the wall from the wall a

32
00:02:57,520 --> 00:03:02,720
Normal North American circuit is 1.8 kilowatts if you use like a 240 volt

33
00:03:02,720 --> 00:03:07,360
That's what like 3.4 kilowatts this thing draws 45 kilowatts

34
00:03:09,080 --> 00:03:15,680
It's not even close you cannot plug it into the wall it will draw too much current by a lot. Yep. We're about to go to the red line

35
00:03:16,280 --> 00:03:18,280
See

36
00:03:19,280 --> 00:03:22,600
These are the batteries that we got to power it, okay

37
00:03:24,160 --> 00:03:26,320
So this is Alex's first time seen it

38
00:03:27,680 --> 00:03:30,200
That is a really nice battery. Oh, bro

39
00:03:30,760 --> 00:03:35,840
Yes, they also like they're also cost a hundred and sixty nine dollars each and we got 15 of them

40
00:03:35,840 --> 00:03:39,600
So this is a 4s lipo battery. So that means there's four

41
00:03:40,280 --> 00:03:44,360
cells in series It's rated for 130 C

42
00:03:44,720 --> 00:03:52,960
So what that means for people that don't do cars this capacity is 6,000 milliamps in other words six amp hours, okay?

43
00:03:53,760 --> 00:03:57,520
But you in theory can discharge it at

44
00:03:58,720 --> 00:04:03,680
130 times its capacity so in theory you could draw over 600 amps

45
00:04:04,160 --> 00:04:08,560
From this battery and it still be fine in theory. We're not going to do that

46
00:04:08,560 --> 00:04:13,780
We're only gonna go do about 260 maybe 270 not much beyond that

47
00:04:14,400 --> 00:04:19,840
But this is only 4s. We need 24 s to power this

48
00:04:20,440 --> 00:04:25,160
Okay, so if you're good at math, you know where I'm going. Well, what's 4s?

49
00:04:25,800 --> 00:04:33,120
Plus another 4s plus another 4s plus another 4s six times you get 24 s

50
00:04:33,960 --> 00:04:36,320
So we're gonna put six of these in series

51
00:04:37,320 --> 00:04:42,480
Then for out of good measure, we're gonna build another six series and

52
00:04:43,200 --> 00:04:45,840
Stick it on top and put those two in parallel

53
00:04:46,520 --> 00:04:52,280
For extra capacity because at Phil tilt we will drain this battery in three minutes

54
00:04:57,200 --> 00:05:03,160
So that's some behind-the-scenes that may or may not make it into the final cut, but that's how much thinking went into this

55
00:05:03,160 --> 00:05:08,040
Let's just say we're gonna test this before getting Linus in here because we're actually nervous

56
00:05:08,680 --> 00:05:15,040
That we're gonna blow the tempered glass out the sides. Yeah, that is a bit might just remove the side panels

57
00:05:15,080 --> 00:05:21,000
No, we're doing that on camera. We need to try that. Okay. Well, then we need to build like a freaking like plexiglass structure

58
00:05:21,000 --> 00:05:25,800
Yeah, this can 100% this is a rat RAM. This is behind-the-scenes rambling

59
00:05:26,680 --> 00:05:35,120
We do need to start a roll though, okay How should we say this in a way that makes sense instead of just rambling to the social team for a while?

60
00:05:36,600 --> 00:05:39,680
That's a good question good thing. We have a right again. Yeah

61
00:05:40,720 --> 00:05:45,400
Yeah, I guess that's my problem Do we want to like intro the fan?

62
00:05:46,800 --> 00:05:52,360
We'll intro the fan in the intro. Okay in the intro. This is this is just post-intro. This is post-intro

63
00:05:53,080 --> 00:05:55,960
So this is kind of when we're like we've got the fan

64
00:05:56,640 --> 00:06:02,220
It's really scary And we need to make sure that we don't blow ourselves up. Okay

65
00:06:03,760 --> 00:06:08,600
How we're going to do that is by using this thing which on its own

66
00:06:09,520 --> 00:06:14,880
Not too bad This thing is actually pretty scary once again

67
00:06:14,880 --> 00:06:21,560
Well, we do need to tell the story of how we came we need to tell the battery the battery story because that was a significant pull

68
00:06:22,280 --> 00:06:28,180
I actually power it. I think that we have Linus do that on Friday in a roll. Okay, that's that's fine

69
00:06:28,200 --> 00:06:33,160
Okay, so you script that I'm gonna have the crate. We're gonna have the hook. You're gonna the intro

70
00:06:34,560 --> 00:06:37,840
Then we want to what cut to us building the actual battery

71
00:06:38,360 --> 00:06:42,480
Or do you want to cut to Linus explaining the choice of making the battery?

72
00:06:44,080 --> 00:06:50,000
So I guess are we we're not making the battery today. That's a give you oh, we are yeah, okay

73
00:06:50,480 --> 00:06:54,680
That's why I have a little stuff. Yeah, we can we were testing and making the battery

74
00:06:55,720 --> 00:07:01,520
I thought we were just testing Do you want Linus to make to try to make the battery? No, not really

75
00:07:03,800 --> 00:07:10,080
The main things that we want to do today on camera is show this being a

76
00:07:11,320 --> 00:07:17,000
Sketchy solution, but a lot less sketchy just to just to test it. Yeah, it's a lot less sketchy than having

77
00:07:17,840 --> 00:07:25,240
200 500 amps available to us and we like take this apart. Yeah, good. Look. Yeah. Do you want to start by doing that?

78
00:07:26,760 --> 00:07:32,600
This is the AC is gonna power it. It's a complex piece of electronic thing. We're gonna take it but

79
00:07:33,960 --> 00:07:41,000
Sure Legally, you're not allowed to use this for human flight, but people have

80
00:07:41,000 --> 00:07:48,240
Oh All right, there's legal in what you yeah, and camera is rolling

81
00:07:50,160 --> 00:07:54,460
Bassie fan VF 390 day one

82
00:07:57,800 --> 00:08:00,300
This is going multiple days, you know that I

83
00:08:01,480 --> 00:08:06,720
Guess do we have anything else to say really? I mean the only thing I have to say is

84
00:08:07,680 --> 00:08:11,720
This is the ESC That's the fan and this

85
00:08:15,600 --> 00:08:17,600
It feels like it's like

86
00:08:18,720 --> 00:08:21,160
Tidy-ass little thing powering just death

87
00:08:22,200 --> 00:08:25,080
Roland we have these big capacitors here

88
00:08:25,960 --> 00:08:29,800
to talk about There's this IC

89
00:08:30,800 --> 00:08:36,080
Keep the fun You've got our PWM lead

90
00:08:39,680 --> 00:08:41,680
Okay

91
00:08:43,160 --> 00:08:48,240
PWM lead we've got our firmware controller, whatever settings leave

92
00:08:54,800 --> 00:08:59,560
This is very similar technology to what's in an EV car that takes power from the battery and

93
00:09:00,320 --> 00:09:06,160
Converts it to what the motor needs to go forward except we're gonna thank in the middle of the cut

94
00:09:10,200 --> 00:09:12,200
Hmm

95
00:09:13,720 --> 00:09:19,400
That takes power from the battery and converts it to the three-phase unit to run the induction motor for the car

96
00:09:20,200 --> 00:09:24,000
Instead of making the cargo for we're gonna attach to a fan and

97
00:09:25,320 --> 00:09:27,360
Yeah, make our computer go backwards maybe

98
00:09:30,360 --> 00:09:33,520
Yes, is that b-roll ready that is

99
00:09:40,200 --> 00:09:42,200
I

100
00:09:45,040 --> 00:09:48,880
Know Could have made a really awkward joke there, but decided against it

101
00:09:49,680 --> 00:09:56,960
Do you have any more of these guys? No, no that one came with the ESC. Oh, I have a whole bunch of five millimeter ones

102
00:09:57,880 --> 00:10:00,360
Doesn't go in. Yeah, five doesn't go into eight. Hmm

103
00:10:01,360 --> 00:10:05,200
Quick math You could do

104
00:10:05,200 --> 00:10:09,000
Just take some more eight gauge wire. This is all the eight gauge wire

105
00:10:10,440 --> 00:10:13,760
Like that that's all the eight gauge wire. Yeah, that expensive me

106
00:10:14,200 --> 00:10:17,680
Like this. So this was like this was like 60 bucks

107
00:10:18,520 --> 00:10:26,680
That was 60 bucks. Yeah from Digikey I could have ordered a cheaper from somewhere else, but there was a lead time issue. Oh, yeah

108
00:10:28,600 --> 00:10:33,520
I should have brought some of the wire that I have. No, it's not high enough current. This is this is silicon sheathing

109
00:10:33,520 --> 00:10:37,920
It can handle we only need to handle 10 amp. Oh, yeah, okay for that. Yeah, okay

110
00:10:38,320 --> 00:10:44,600
We could use smaller wires and then like, oh, yeah, okay, I see the problem now. Yeah

111
00:10:46,280 --> 00:10:50,200
One of my ways to be doing the game. Oh, I mean, yeah, okay

112
00:10:56,680 --> 00:11:00,520
I need a snippet I need a snipsnip thing

113
00:11:00,520 --> 00:11:07,040
Oh There's some flash cutters. We're gonna cut some things fleshly

114
00:11:09,040 --> 00:11:16,280
Oh, that doesn't have a battery, does it? Yeah, I feel like we're gonna break this thing to taste so small

115
00:11:16,280 --> 00:11:18,280
Oh

116
00:11:39,840 --> 00:11:44,520
Oh This is kind of sketchy

117
00:11:45,440 --> 00:11:50,160
That went somewhere, I don't know where it went Someone's gonna find it later

118
00:11:50,800 --> 00:11:52,800
And this is why the shop is dirty

119
00:11:55,680 --> 00:11:58,860
Alex, yeah, it doesn't fit your big enough

120
00:12:00,520 --> 00:12:03,280
I mean, I could just try and force it

121
00:12:04,080 --> 00:12:11,080
I mean, I am gonna snip this off like a lot sooner anyway. I really should have just brought some stuff from my house

122
00:12:11,680 --> 00:12:19,440
A bunch of 8-gauge and 4-gauge wires and all the connectors. 4-gauge? Yeah, this is 6-gauge. It was like, yeah, thick board. Yeah

123
00:12:19,440 --> 00:12:27,000
For what? Sound? Yeah, I don't know Sounds like Stundra. Yeah, it wouldn't handle the max current that we're gonna send through. It wouldn't be 260 amp, would it?

124
00:12:27,640 --> 00:12:34,160
Yeah, no, it's like CCA, which is why it needs to be big. It's difficult to find like cable that can actually handle

125
00:12:35,000 --> 00:12:41,200
hundreds of amps That's not like this thick and completely like stupid to work with

126
00:12:42,280 --> 00:12:47,680
Find a way to connect that into that thing and then we're good. I'm gonna try and strip this

127
00:12:50,200 --> 00:12:52,200
Yeah, yeah

128
00:12:53,960 --> 00:12:55,960
Bye

129
00:12:57,800 --> 00:13:05,480
Or like the engineering workshop is like full of like stripped off pieces of wire because I don't know why I think I think I could

130
00:13:05,480 --> 00:13:10,100
Subcheap, I don't bother buying like proper wire strippers. I just use the

131
00:13:11,280 --> 00:13:13,280
cut-and-flip method

132
00:13:15,080 --> 00:13:18,320
This is going this fine, and we haven't even started building the battery pack yet

133
00:13:21,480 --> 00:13:25,080
Man this tape is like sticking to my freaking noise. I'm gonna cut. Yeah

134
00:13:29,080 --> 00:13:33,000
Just sticking to my head. Do we know if there's any sort of protection on here?

135
00:13:33,720 --> 00:13:41,200
Uh Given this was incredibly cheap and from Amazon. Okay. Oh, this is fuses. Oh, yeah, these are cool

136
00:13:41,200 --> 00:13:45,960
Well, I'm just gonna like jam the wire, and then I don't know where they like it's very it's very like

137
00:13:46,440 --> 00:13:50,140
Strandy wire so the spokes could go everywhere. Mm-hmm

138
00:13:51,360 --> 00:13:53,360
You could just tend the wire

139
00:13:54,720 --> 00:13:59,960
I'm gonna say that for later You'll see why when you try and turn this wire

140
00:14:03,200 --> 00:14:08,880
Uh You know what we could have done we could have had a fuse on the battery pack

141
00:14:13,240 --> 00:14:20,240
For the video we need to wire to the trigger. Yeah, it's like just sit there be like run the benchmark Alex

142
00:14:24,080 --> 00:14:26,440
Then again, do we actually want that as an option

143
00:14:33,520 --> 00:14:35,520
I

144
00:14:43,760 --> 00:14:49,560
Are you commenting that we need double A's for that to work. Yeah, I didn't know that. Oh, okay. Never mind. He knew that

145
00:14:50,920 --> 00:14:55,040
I thought we're gonna get that he's gonna be like why is it working Kyle?

146
00:14:57,040 --> 00:15:02,360
That went better in my head than actually went to real life. It's okay. Do we have double is the camera done does

147
00:15:03,280 --> 00:15:13,400
Thank you Creative Warehouse is not the size of like the whole company when I joined. Yes. It's awesome. Oh crazy

148
00:15:16,320 --> 00:15:21,000
And that was like success. Yeah, so from six to three

149
00:15:21,760 --> 00:15:28,360
You basically went from 15 to 25 because I was a 26th person. Yeah, and then from

150
00:15:29,040 --> 00:15:31,440
my time to now it's like

151
00:15:32,440 --> 00:15:39,320
107 Absolutely explode. Anyways, I'm sure we beat that horse or not

152
00:15:40,400 --> 00:15:46,220
Yeah, that's all just gonna be a full plane. Yeah, I'm sorry to the editor. That's all not a rule. Yeah

153
00:15:47,000 --> 00:15:50,520
Be prepared for explosion. I may be made up on the safety glasses

154
00:15:52,080 --> 00:15:55,000
This is probably okay. Do you want to turn it off? Is it up?

155
00:15:55,920 --> 00:16:02,220
Yes, you can turn it you can turn the output off. Okay, so when I read on the internet, this is supposed to be the connection method

156
00:16:06,280 --> 00:16:12,560
It's fine everything's fine. Okay, so the connection method that I read up was you plug the hot side in

157
00:16:14,280 --> 00:16:16,280
Okay

158
00:16:17,400 --> 00:16:19,400
Then you plug this in

159
00:16:21,040 --> 00:16:23,720
No spark and then we wait

160
00:16:25,000 --> 00:16:27,000
So it caps a child

161
00:16:28,080 --> 00:16:33,120
Probably not very long that's supposed to be it. We should insulate that at some point. Yeah. Yeah

162
00:16:37,320 --> 00:16:42,240
Okay, now we smell from magic smoke So if you smell the very funky smell

163
00:16:42,880 --> 00:16:49,680
It's Alex See, I'm not the only person who asked this question because it's the top search thing on YouTube

164
00:16:49,760 --> 00:16:52,820
How to power a fly sky receiver, which is listening

165
00:16:53,500 --> 00:16:59,180
I don't do RC So I am being educated by Google

166
00:16:59,980 --> 00:17:06,220
And the RC controller, that's the thing that connects to so that yeah

167
00:17:06,220 --> 00:17:09,380
So basically when I when we go room room

168
00:17:10,500 --> 00:17:15,900
You somehow need to tell that thing to go from room. Yeah, so because it's wireless. This is the transmitter

169
00:17:15,900 --> 00:17:21,060
This is the receiver. Okay, this gets powered by the batteries that Alex just went and fetched

170
00:17:22,060 --> 00:17:26,020
So this will get power but

171
00:17:26,020 --> 00:17:28,520
This thing needs power and

172
00:17:29,420 --> 00:17:31,620
Currently, I don't know how it gets power

173
00:17:33,420 --> 00:17:39,160
So this is a six-channel receiver you can see ch1 ch2 ch3 blower all the way six

174
00:17:39,180 --> 00:17:43,660
Then there's also a bind on the top right, so

175
00:17:43,820 --> 00:17:49,820
My assumption is that you can bind. Well, you can bind this to different remotes by shorting out some

176
00:17:50,180 --> 00:17:55,660
Terminal in here and putting them to bind mode and then you do something with a receiver and then it pairs, right?

177
00:17:56,500 --> 00:17:59,060
My assumption is that if I put

178
00:17:59,900 --> 00:18:04,580
Voltage on the bind just like five volts. It'll power the receiver

179
00:18:04,580 --> 00:18:09,380
I just want to make sure that that's actually the case so that if I do it. It doesn't blow it up

180
00:18:10,780 --> 00:18:13,860
Mainly because we don't have extra and I don't want to blow stuff up. So

181
00:18:14,300 --> 00:18:17,500
We might actually have extra for that, but yeah, yeah, yeah, yeah. Oh

182
00:18:18,980 --> 00:18:22,540
My god, what oh just seeing that

183
00:18:23,980 --> 00:18:28,940
Yeah sneak peak there it is there we go. There we go. Ha ha

184
00:18:31,220 --> 00:18:37,860
Position let's move it down I'm going to try and get like maybe two in the same frame

185
00:18:40,060 --> 00:18:45,680
sideways position Two in the same frame. There we go. There's two in the same frame

186
00:18:47,300 --> 00:18:53,180
All right, so from there to there is 50 times a second. All right, so from and

187
00:18:53,900 --> 00:18:59,000
Then there's one hump. There's another hump and then when you change it. It'll change both of them

188
00:18:59,940 --> 00:19:01,940
right so

189
00:19:03,180 --> 00:19:07,500
From a DC side what that's actually doing is you're starting with five volts

190
00:19:07,500 --> 00:19:13,900
But because you're only on for like what is essentially 10% of the time you actually read like 10% of the voltage out

191
00:19:13,900 --> 00:19:17,500
If you if you if you just would have probed it with DC, but what the actual

192
00:19:18,860 --> 00:19:23,900
ESC sees is sees that bump it reads the duty cycle and then

193
00:19:24,980 --> 00:19:29,420
Changes the fan speed accordingly That's a very high-level definition of what it is

194
00:19:31,300 --> 00:19:36,300
Cool Teen to change that's a roll right those two things. I don't know

195
00:19:36,980 --> 00:19:43,460
Change that's very potentially just more flow plane exclusive, but a little bit of that explanation will be in for sure

196
00:19:43,460 --> 00:19:50,020
Or you can just like Remove me out and have someone use a little bit more lesser verbose explain it

197
00:19:50,020 --> 00:19:54,740
I don't know. I think that was a pretty good explanation. I Dig it cool

198
00:19:55,300 --> 00:19:59,620
Nope Emma

199
00:20:00,180 --> 00:20:02,180
Thank you

200
00:20:03,740 --> 00:20:05,740
I

201
00:20:08,580 --> 00:20:15,900
The back brace for the computer So it doesn't fly that way. It doesn't know where it goes. Um in theory no

202
00:20:16,540 --> 00:20:24,980
Do we have a big old heat shrink? Do we have a big old heat shrink? I was gonna use electrical tape, but yeah inside the bottom drawer of the electronics cabinet

203
00:20:28,180 --> 00:20:32,140
You probably don't want to be on this end when that fan is on this side

204
00:20:33,300 --> 00:20:38,220
You don't necessarily want to be here, but it's much better than being on this. Yes

205
00:20:38,580 --> 00:20:43,380
Because if you think about it, these pins right here are the thing that are going to kill you

206
00:20:43,540 --> 00:20:48,940
So if one of these explodes, it's already loaded up so it shoots this way

207
00:20:49,500 --> 00:20:52,380
So if this fan explodes everything's coming out

208
00:20:53,500 --> 00:20:56,620
Like that which is a bit counterintuitive because you kind of think it would go down

209
00:20:56,620 --> 00:21:01,380
But you know there might be some Yeah, majority of the big chunks are gonna go

210
00:21:01,380 --> 00:21:06,540
Yeah, this blade is going to try and heat itself in that direction. Yeah, this is more of a sandy check

211
00:21:06,540 --> 00:21:08,540
Yeah, and then we're gonna build a big battery

212
00:21:14,700 --> 00:21:22,260
It's a big fan, hey, I Was thinking maybe this big but like holy crap. That's a big fan. Yeah, big fan

213
00:21:22,860 --> 00:21:26,580
All right, wait get get like everything expensive out the freaking way

214
00:21:28,620 --> 00:21:30,620
Oh

215
00:21:55,740 --> 00:22:00,620
That's 10% power I

216
00:22:02,300 --> 00:22:04,300
Needed that

217
00:22:08,820 --> 00:22:10,820
You found more I did oh

218
00:22:12,940 --> 00:22:19,180
Hello spider. Oh, no, it's a mosquito. Ah, geez that's a big sucker. You see it

219
00:22:19,860 --> 00:22:21,860
Where the freaking on

220
00:22:27,340 --> 00:22:31,420
There you go weapons velocity mosquito. Yep
