1
00:00:00,160 --> 00:00:06,720
this is the most expensive xbox controller in the world it's made of one

2
00:00:04,640 --> 00:00:14,880
and a half kilograms so that's a little under four pounds of solid gold and

3
00:00:11,280 --> 00:00:16,480
you might be wondering how we made it

4
00:00:14,880 --> 00:00:20,240
so i just got an email back from expert casting they did some test casts and

5
00:00:18,560 --> 00:00:27,119
they can do it yes it's going to be about one and a half

6
00:00:23,920 --> 00:00:28,160
kilograms of 18 karat gold

7
00:00:27,119 --> 00:00:33,599
wow which is going to be 87

8
00:00:30,880 --> 00:00:33,599
500

9
00:00:34,160 --> 00:00:40,960
well you only live once gold xbox controller here we come this video is

10
00:00:38,879 --> 00:00:44,879
brought to you by the volta 2.0 a universal reliable fast charging

11
00:00:42,800 --> 00:00:48,480
magnetic cable that works across all usb devices including with data transfer

12
00:00:46,800 --> 00:00:52,200
capabilities check it out today at the link in the video description

13
00:00:58,960 --> 00:01:05,680
let's take a moment to appreciate just how challenging this is going to be by

14
00:01:02,960 --> 00:01:10,000
cracking open this pulse red xbox series x controller

15
00:01:07,680 --> 00:01:13,360
starting with the battery cover i guess for disassembly we pry off the outer

16
00:01:11,680 --> 00:01:17,680
shell starting with these hand grips at the back and then remove all the screws

17
00:01:15,680 --> 00:01:21,520
including ah yes this sneaky little boy

18
00:01:19,680 --> 00:01:26,720
under the sticker here my warranty is now void i think hello

19
00:01:24,479 --> 00:01:30,320
ah wow

20
00:01:27,680 --> 00:01:33,520
that is a complicated part if we want the functionality of the finished

21
00:01:31,439 --> 00:01:37,680
controller to be exactly the same though we are going to have to recreate this

22
00:01:35,200 --> 00:01:42,560
one for one and that won't be easy thin components particularly ones with

23
00:01:40,159 --> 00:01:47,040
lots of intricate detail are especially difficult to cast that's why we won't be

24
00:01:44,880 --> 00:01:52,399
attempting this here in our own shop which brings us to expert castings here

25
00:01:49,280 --> 00:01:54,640
in beautiful downtown vancouver but as

26
00:01:52,399 --> 00:02:01,200
grand as the entryway looks things are about to get down and dirty

27
00:01:58,079 --> 00:02:02,320
unlike ourselves expert castings are

28
00:02:01,200 --> 00:02:06,320
just that experts with accolades like being one of

29
00:02:04,479 --> 00:02:11,360
two places in canada that can work on a tiffany piece and making jewelry for

30
00:02:08,879 --> 00:02:16,640
disney 50 shades of grey once upon a time and many more

31
00:02:13,920 --> 00:02:20,959
now they first tried to convince us to cast our piece in bronze then gold

32
00:02:18,959 --> 00:02:26,160
played it this is generally what's done for movie props like this one right here

33
00:02:23,760 --> 00:02:30,720
it's way cheaper and usually gives a better result anyway but

34
00:02:28,640 --> 00:02:34,720
problem is this was one of those videos where we came up with the title first

35
00:02:33,120 --> 00:02:39,920
and then figured out how to fill in the gaps later so we were stuck cutting a

36
00:02:37,599 --> 00:02:42,959
fat order of pure gold to the royal canadian mint

37
00:02:41,280 --> 00:02:47,360
they just brought this over and look at it we have one kilogram of gold right

38
00:02:45,440 --> 00:02:53,040
here so this is a professional engineer's salary in my hands and it's

39
00:02:50,319 --> 00:02:57,840
shocking how heavy it is given like the size i'm surprised how small it is

40
00:02:56,480 --> 00:03:01,840
look at this thing forecasting you first have to create a

41
00:03:00,080 --> 00:03:05,680
negative of the shape that you want for the metal to be poured into adam is

42
00:03:04,239 --> 00:03:11,200
going to be taking care of this step called spruing wax gets heated up by a

43
00:03:08,480 --> 00:03:15,760
low temperature soldering iron and stuck to parts of our controller this will

44
00:03:13,200 --> 00:03:21,599
create pathways for the gold to pour into in the past rings would be

45
00:03:18,080 --> 00:03:24,319
painstakingly hand carved out of wax but

46
00:03:21,599 --> 00:03:28,560
now most parts are just 3d printed some parts they cast all the time like

47
00:03:26,239 --> 00:03:33,519
this anchor so for that they've created a negative that they can inject wax into

48
00:03:31,120 --> 00:03:38,480
using this wax pot all of the pieces on the sprue need to be organized kind of

49
00:03:35,599 --> 00:03:43,280
like an upside down tree this shape makes it easier for the molten metal to

50
00:03:40,720 --> 00:03:47,599
flow into the cavities while also making it easier for air to find its way out

51
00:03:45,840 --> 00:03:52,400
that's critical because it's super important to accurately weigh the

52
00:03:49,360 --> 00:03:54,159
plastic and the wax on the sprue and use

53
00:03:52,400 --> 00:03:58,400
the density of those materials compared to gold to figure out how much metal

54
00:03:56,400 --> 00:04:02,480
will be needed to fill the mold too little metal and there won't be enough

55
00:04:00,080 --> 00:04:07,040
force pushing down into the mold or it might just not fill at all and too much

56
00:04:04,640 --> 00:04:11,680
metal well that's just wasteful and that's very expensive waste now we need

57
00:04:09,920 --> 00:04:17,359
to create the investment which will harden around our sprue simply add a

58
00:04:14,439 --> 00:04:21,440
.395 ratio of water to plaster powder in a large bowl and then combine with a

59
00:04:19,359 --> 00:04:25,360
kitchen mixer for two minutes place the mixture under vacuum for one minute 40

60
00:04:23,360 --> 00:04:29,120
seconds to remove bubbles pour the plaster into the mold and place under

61
00:04:27,360 --> 00:04:33,120
vacuum again for another minute and 40 seconds from here the whole thing is

62
00:04:31,040 --> 00:04:37,520
placed in the kiln at 700 degrees celsius overnight this will give the wax

63
00:04:35,199 --> 00:04:42,320
and plastic time to melt and then burn off leaving only voids behind now we're

64
00:04:40,000 --> 00:04:45,840
basically ready to melt the gold but there's one problem our hunk of gold is

65
00:04:44,639 --> 00:04:49,520
too big if it makes you feel any better this is

66
00:04:47,919 --> 00:04:54,080
much more painful for me to watch than it is for you so if you could go to

67
00:04:51,639 --> 00:04:57,440
lttstore.com right now to ease the pain that'd be great thanks now you guys

68
00:04:56,080 --> 00:05:01,280
might have guessed that during this chopping process tiny flakes of gold

69
00:04:59,919 --> 00:05:05,919
will fall off it's not too bad the flakes coming off

70
00:05:03,759 --> 00:05:11,440
of our piece here total only about 10 to 20 cents but they do add up they

71
00:05:09,440 --> 00:05:16,000
actually sweep the floor here and the benches every day chuck it in this big

72
00:05:13,840 --> 00:05:20,800
bucket and in a year it can catch about a hundred thousand dollars in tiny

73
00:05:18,560 --> 00:05:26,560
pieces of gold our second problem is that the royal canadian mint is awesome

74
00:05:23,840 --> 00:05:31,120
and their four nines gold bars are just too pure

75
00:05:28,320 --> 00:05:38,000
but okay seriously though even pleb american us mint gold would be much too

76
00:05:33,919 --> 00:05:39,759
ductile for actual use in fact

77
00:05:38,000 --> 00:05:44,320
oh yeah it's so soft that it would probably

78
00:05:42,320 --> 00:05:48,639
deform in your hands the first time you got head shot by some 11 year old in

79
00:05:46,080 --> 00:05:56,240
call of duty so then summer here we'll be expertly creating our alloy using 450

80
00:05:52,639 --> 00:06:00,080
grams of gold per 150 grams of alloy

81
00:05:56,240 --> 00:06:05,520
blend we're using number 220 which is 12

82
00:06:00,080 --> 00:06:07,840
zinc 11.5 silver and 76.5 percent copper

83
00:06:05,520 --> 00:06:13,280
blends are chosen mostly for the color that they produce and ours should give

84
00:06:09,919 --> 00:06:15,520
us a nice orangey yellow look finally

85
00:06:13,280 --> 00:06:20,479
it's time to melt some metal baby using an induction oven the gold is heated up

86
00:06:17,360 --> 00:06:23,039
to 100 degrees celsius and our mold is

87
00:06:20,479 --> 00:06:29,120
then removed from the kiln at 600 degrees celsius the thing is if the mold

88
00:06:25,520 --> 00:06:31,199
is too cool then the gold might solidify

89
00:06:29,120 --> 00:06:35,600
before it fills in all the cavities before the gold can be added though all

90
00:06:33,440 --> 00:06:39,759
the air in the mold has to be replaced with an inert hydrogen nitrogen mixture

91
00:06:37,919 --> 00:06:44,319
this helps prevent the gold alloy from reacting with the air while it's molten

92
00:06:42,319 --> 00:06:49,680
so when everything's ready they just lift up the center column that's lined

93
00:06:46,080 --> 00:06:52,400
up with the center sprue of our mold and

94
00:06:49,680 --> 00:06:56,240
all the gold flows in is it going is it going did it go can i see it

95
00:06:56,479 --> 00:07:01,440
molten gold david is it good

96
00:07:00,240 --> 00:07:07,039
yeah oh that doesn't sound very confident we

97
00:07:03,520 --> 00:07:09,280
didn't put in enough gold oh

98
00:07:07,039 --> 00:07:13,520
the concern right now is that there's a bunch of tunnels that the gold is

99
00:07:10,880 --> 00:07:17,599
supposed to flow down and there's one that it didn't go down but there's like

100
00:07:15,919 --> 00:07:22,639
five that it did apparently that's what she was poking at she was poking to see

101
00:07:20,240 --> 00:07:27,520
if the tunnels were full let's see if it worked ladies and gentlemen

102
00:07:24,800 --> 00:07:27,520
here we go

103
00:07:28,240 --> 00:07:34,400
oh bomber

104
00:07:32,479 --> 00:07:38,240
oh wow it's heavy i guess we might not even need to worry

105
00:07:36,160 --> 00:07:42,160
about that though because that's covered like all of this in here you don't see

106
00:07:40,319 --> 00:07:45,759
well because of the uh holding it together

107
00:07:43,440 --> 00:07:49,280
i think it's fine actually you might be right

108
00:07:46,720 --> 00:07:54,960
it's actually the texture oh my god it has the texture of the xbox controller

109
00:07:52,800 --> 00:07:58,639
i mean i i know i shouldn't be surprised but like

110
00:07:56,479 --> 00:08:01,280
but it but it did it kind of looks like ass hey

111
00:07:59,919 --> 00:08:04,960
right like that's my ass tens of thousands of dollars and

112
00:08:03,360 --> 00:08:08,639
it just doesn't look like anything tens of thousands of dollars of ass

113
00:08:06,879 --> 00:08:13,599
of course what you saw was only the back piece of the controller so the front the

114
00:08:11,360 --> 00:08:16,800
shoulder and trigger buttons as well as i don't know whatever you call these

115
00:08:14,879 --> 00:08:20,080
back pieces and the battery cover were all done ahead of time due to size

116
00:08:18,800 --> 00:08:25,199
limitations so with a combination of a soap bath

117
00:08:23,280 --> 00:08:31,039
scrubbing with a toothbrush scraping with a pick and

118
00:08:27,919 --> 00:08:32,240
even some actual removal of the material

119
00:08:31,039 --> 00:08:36,560
this will turn in to this

120
00:08:35,599 --> 00:08:42,560
now this was our first cast and it was pretty good but there are some small

121
00:08:40,640 --> 00:08:47,600
surface finish problems once it's cleaned up we should be able

122
00:08:44,399 --> 00:08:49,680
to go from a more satin like finish to a

123
00:08:47,600 --> 00:08:53,440
super shiny one like you actually see on this corner here of course there are

124
00:08:52,000 --> 00:08:57,279
still some problems that we have to solve like for example what are you

125
00:08:55,839 --> 00:09:02,160
going to do about the parts where the sprue was joined to the original plastic

126
00:09:00,880 --> 00:09:07,440
i don't know but i can't wait to see if the thing actually comes

127
00:09:05,200 --> 00:09:10,160
together so this is it ladies and gentlemen

128
00:09:08,640 --> 00:09:13,200
test fit time oh

129
00:09:11,680 --> 00:09:18,320
that's it okay where's my uh where's my battery cover at alex can you be can you

130
00:09:15,279 --> 00:09:18,320
be my third hand here

131
00:09:21,120 --> 00:09:27,760
oh man once all the sprue crap is on there and

132
00:09:25,680 --> 00:09:32,880
this fits together this is gonna be crazy

133
00:09:30,560 --> 00:09:35,920
guys do not miss the met the next part of this

134
00:09:34,240 --> 00:09:40,480

kaiwa or halo switches it features a floating key design with dual usb type-c

142
00:10:07,440 --> 00:10:15,040
connectors and weighs 964 grams the only way it could be

143
00:10:12,640 --> 00:10:15,040
heavier

144
00:10:15,680 --> 00:10:22,160
is if they made it out of a heavier metal

145
00:10:19,360 --> 00:10:25,519
so check it out at the link down below if you guys enjoyed this video and you

146
00:10:23,600 --> 00:10:30,480
love crazy projects maybe you'd like our water cooled playstation 4. that's right

147
00:10:28,079 --> 00:10:36,640
we did one of those away a while back let's uh we don't have anything current

148
00:10:32,880 --> 00:10:36,640
gen look we're working on it okay
