1
00:00:00,160 --> 00:00:07,359
in previous years at ltx jake's contribution to the like incredible

2
00:00:04,640 --> 00:00:13,759
experiences that we've created have been playing racing games on the 16k and 10k

3
00:00:11,120 --> 00:00:20,000
ultrawide gaming setups and frankly they were smash hits good job jake

4
00:00:17,359 --> 00:00:23,439
but this year for our racing experience we're not content to settle for

5
00:00:22,320 --> 00:00:28,480
bezels or even virtual cars

6
00:00:26,320 --> 00:00:34,480
this is next level my friends what if instead of a video game car on a screen

7
00:00:32,000 --> 00:00:37,600
we could drive actual cars

8
00:00:38,800 --> 00:00:46,879
in vr i mean yeah okay they're they're rc cars

9
00:00:43,760 --> 00:00:47,680
but like come on close enough right sick

10
00:00:46,879 --> 00:00:53,600
right that sounds pretty cool

11
00:00:50,000 --> 00:00:55,520
just like our sponsor ridge wallet

12
00:00:53,600 --> 00:01:00,320
ridge wallet is the sleek way to keep wallet bulge down with its compact frame

13
00:00:58,000 --> 00:01:06,180
and it offers rfid blocking inner plates use code ltt to save 10 and get free

14
00:01:02,559 --> 00:01:11,169
worldwide shipping at the link below

15
00:01:14,080 --> 00:01:19,920
let's break this down so first

16
00:01:17,600 --> 00:01:24,240
we've got to figure out how to control our steering servo here

17
00:01:22,479 --> 00:01:29,200
with a steering wheel as well as figuring out how to control

18
00:01:26,320 --> 00:01:33,200
our esc or electronic speed controller with a throttle and a brake pedal

19
00:01:31,759 --> 00:01:37,759
and then there's the video stuff like how do we even mount it what are we gonna use like there's a lot of

20
00:01:36,479 --> 00:01:43,040
questions here yeah uh furthermore getting that video

21
00:01:40,240 --> 00:01:47,680
feed to the headset is another issue so we need something that's high quality

22
00:01:45,119 --> 00:01:51,280
enough that you can really see where you're going through it and also low

23
00:01:49,600 --> 00:01:54,720
latency enough that you don't just want to immediately throw up we're probably

24
00:01:53,360 --> 00:01:58,240
getting ahead of ourselves a little bit though because before we can do any of

25
00:01:56,399 --> 00:02:01,920
that stuff we need to settle on a platform or a car there's a lot of

26
00:02:00,399 --> 00:02:05,200
options out there obviously but we need something that's not crazy expensive

27
00:02:03,680 --> 00:02:09,679
because you know you're kind of cheap we need something that's going to be reliable with good battery life because

28
00:02:07,759 --> 00:02:13,840
this is going to be seven plus hours for two days and it needs to be not too big

29
00:02:12,000 --> 00:02:17,120
or too fast because both of those things are going to contribute to motion sickness yeah if you're like ripping

30
00:02:16,080 --> 00:02:21,040
around like like go that fast like four inches

31
00:02:19,680 --> 00:02:26,000
from the ground we want to keep our vomit quota for ltx pretty low you're

32
00:02:23,120 --> 00:02:30,800
gonna be done now of course it also still needs to be big enough to house

33
00:02:28,080 --> 00:02:36,319
all the first person view hardware and i mean ideally be fun to play with when

34
00:02:33,280 --> 00:02:38,560
we're just done this project right yeah

35
00:02:36,319 --> 00:02:44,080
there we go so turns out there was a bit of a

36
00:02:40,200 --> 00:02:45,440
miscommunication um jake and i define

37
00:02:44,080 --> 00:02:48,959
large a little bit differently so for better

38
00:02:47,760 --> 00:02:53,760
or for worse we ended up with a traxxas slash

39
00:02:51,360 --> 00:02:58,239
two-wheel drive which would be perfect for this project if it was

40
00:02:56,239 --> 00:03:02,160
oh i don't know about 30 percent smaller and

41
00:03:03,440 --> 00:03:08,879
maybe okay okay okay maybe about a fifth of the speed

42
00:03:09,840 --> 00:03:15,599
it's fun though yeah that's fine we can roll with this all

43
00:03:14,319 --> 00:03:18,800
right all right all right well one thing i didn't show you is it

44
00:03:17,599 --> 00:03:25,120
has training mode which cuts the throttle in half you know jake's not so

45
00:03:21,120 --> 00:03:25,120
bad eh we're on the same wavelength here

46
00:03:28,959 --> 00:03:35,200
all right it's it's still pretty quick okay still probably a little faster than we

47
00:03:32,959 --> 00:03:39,440
wanted sorry david getting our steering working with a usb steering wheel was

48
00:03:37,360 --> 00:03:43,440
the first real challenge now we knew thanks to fellow youtuber rc sparks that

49
00:03:42,080 --> 00:03:48,080
there was a steering wheel that would work really well for this setup thanks

50
00:03:45,599 --> 00:03:52,560
to its simple design the thrustmaster ferrari racing wheel and thankfully

51
00:03:50,640 --> 00:03:57,040
thrustmaster was able to supply us with several of them to tinker with and it

52
00:03:54,560 --> 00:04:00,879
looks like with some minor modifications we should be in pretty good shape so

53
00:03:59,120 --> 00:04:07,280
with the rc transmitter and the steering wheel opened up this actually

54
00:04:03,439 --> 00:04:08,879
looks relatively straightforward

55
00:04:07,280 --> 00:04:12,720
hopefully knock on wood so the transmitter just has a potentiometer so

56
00:04:11,120 --> 00:04:17,519
you can see the one behind the steering wheel right here and then it's got a

57
00:04:14,879 --> 00:04:21,840
second one for the throttle so that's pretty cool so if the resistance is the

58
00:04:19,919 --> 00:04:26,160
same between this and there we go the potentiometer here and

59
00:04:25,199 --> 00:04:34,080
well the other one would be in the pedals we'll deal with that later we should be able to just

60
00:04:30,560 --> 00:04:35,120
move the wires over and

61
00:04:34,080 --> 00:04:39,280
yeah they're different so

62
00:04:37,520 --> 00:04:42,880
we're dealing with 10 kilo ohm potentiometers

63
00:04:40,800 --> 00:04:48,400
in the steering wheel and then just five

64
00:04:46,479 --> 00:04:53,040
five five kilo ohms yeah sorry yeah five kilo

65
00:04:50,639 --> 00:04:57,360
ohm for the transmitter okay so

66
00:04:54,720 --> 00:05:02,880
hopefully then what we can do is find some five kilo ohm pots that are a

67
00:04:59,840 --> 00:05:04,720
similar size to what's already in the

68
00:05:02,880 --> 00:05:09,600
steering wheel because we'd rather not have to make adapters or something just

69
00:05:07,039 --> 00:05:13,199
to mount the pot so we can turn the stem on it when we turn the wheel after a

70
00:05:11,600 --> 00:05:17,759
quick trip to the local electronics store jake returned with something

71
00:05:15,039 --> 00:05:22,000
reminiscent of what we previously had although we could tell some minor

72
00:05:19,280 --> 00:05:26,479
modifications were going to be necessary for the pedals we weren't able to

73
00:05:23,919 --> 00:05:30,639
locally source flat sided potentiometers in the resistance that we needed so

74
00:05:28,479 --> 00:05:34,880
while you could probably just drill out the hole in these little gears we

75
00:05:32,800 --> 00:05:37,520
decided to instead 3d print some replacements

76
00:05:36,080 --> 00:05:42,960
as for the steering wheel the potentiometer was really close to

77
00:05:40,000 --> 00:05:47,360
fitting but some cutting and sanding was required to get it nice and snug in

78
00:05:45,120 --> 00:05:51,759
there we went with a super professional hot glue mount for now but by the time

79
00:05:49,600 --> 00:05:56,400
we roll this out at ltx it'll probably be upgraded to jb weld

80
00:05:54,000 --> 00:06:00,800
for wiring we followed along as closely as we could with rc sparx's guide and it

81
00:05:58,880 --> 00:06:05,520
turned out pretty well although we did have to swap our pedals from left to

82
00:06:02,479 --> 00:06:07,360
right as they were reversed okay so

83
00:06:05,520 --> 00:06:13,129
theoretically if you fire that up

84
00:06:13,840 --> 00:06:19,280
turn the chairmail no way

85
00:06:19,360 --> 00:06:24,319
okay well that's the easy one okay

86
00:06:27,120 --> 00:06:33,520
oh i saw it you saw it which is definitely trying we should try the

87
00:06:31,840 --> 00:06:37,600
calibration thing whoa whoa okay you're gonna break it so what we're trying to

88
00:06:35,199 --> 00:06:42,160
do right now is calibrate the pedals because theoretically you can

89
00:06:40,720 --> 00:06:46,000
set up what i guess it would be the receiver yeah the speed control you

90
00:06:44,240 --> 00:06:49,840
ready yeah okay ready uh did you already press it no no sorry

91
00:06:50,560 --> 00:06:58,639
well it's moving at least so we got the throttle is it enough to get it to go

92
00:06:55,520 --> 00:07:00,319
oh not very fast

93
00:06:58,639 --> 00:07:06,080
this might be better though ah it's a little slow

94
00:07:03,039 --> 00:07:09,199
she'll be coming round the mountain when

95
00:07:06,080 --> 00:07:11,280
she comes yeehaw

96
00:07:09,199 --> 00:07:15,680
i feel like we have less throw than we did in the controller because these

97
00:07:13,680 --> 00:07:19,120
because you've got geometry trigger so the ones in the controller are 180

98
00:07:17,440 --> 00:07:23,840
degrees right so you have yeah blah blah blah and then these ones are like 270.

99
00:07:21,440 --> 00:07:28,000
yeah so what if we cut this just cut the stoppers out so while jake

100
00:07:25,919 --> 00:07:32,400
chops up the pedal assembly it's time to talk about the first person view video

101
00:07:30,000 --> 00:07:36,400
setup now we browsed a ton of different tutorials and forums for information

102
00:07:34,639 --> 00:07:41,680
about what the best individual components were for a setup like that

103
00:07:39,120 --> 00:07:47,599
and the conclusion is that it's kind of like building a pc except rather than

104
00:07:44,000 --> 00:07:50,160
what cpu gpu and ram you should buy it's

105
00:07:47,599 --> 00:07:55,440
which video transmitter receiver camera antennas headset and batteries

106
00:07:53,120 --> 00:07:59,919
and there's a lot less community consensus on the benefits of certain

107
00:07:57,520 --> 00:08:04,560
parts over others so at this point it felt like throwing

108
00:08:02,400 --> 00:08:08,879
the company credit card at an rc shop and validating a bunch of different

109
00:08:06,240 --> 00:08:12,639
stuff ourselves might have been our only choice

110
00:08:09,919 --> 00:08:17,919
that is until we found out that dji makes a pretty much plug and play

111
00:08:14,960 --> 00:08:22,000
first-person view camera called ocusync which when paired with their racing

112
00:08:19,360 --> 00:08:26,560
goggles supposedly provides a super low latency and high quality video feed you

113
00:08:24,720 --> 00:08:30,879
know i gotta say as much as i was genuinely looking forward to cobbling

114
00:08:28,800 --> 00:08:34,719
something together and tinkering with it uh given that we're gonna be running

115
00:08:32,320 --> 00:08:39,120
this at a live event with thousands of attendees i'm actually

116
00:08:37,039 --> 00:08:43,360
pretty happy that we found a pre-made solution

117
00:08:40,640 --> 00:08:45,920
one point dji failed to mention to us however

118
00:08:44,320 --> 00:08:49,040
is that see this right here is the receiver and

119
00:08:47,760 --> 00:08:54,800
camera module it actually needs active cooling

120
00:08:51,839 --> 00:08:58,320
otherwise it can overheat i mean i guess that makes sense given

121
00:08:56,560 --> 00:09:03,680
that this thing is designed to be used on open air or like racing drones

122
00:09:01,200 --> 00:09:08,399
but anyway it's fine because we can just simulate that airflow with a little five

123
00:09:05,839 --> 00:09:13,360
volt knock to a fan a 3d printed bracket and then some of these old enzo tech uh

124
00:09:11,200 --> 00:09:17,200
heat sinks okay so now that jake is pretty much done with the hack job

125
00:09:14,880 --> 00:09:20,720
behind me i guess it's time for me to try and find some

126
00:09:18,560 --> 00:09:23,440
places through the grill well look it's not i know it's not going to be perfect

127
00:09:22,399 --> 00:09:30,399
today it's i think about it what we're going to have to do is cut some holes in this

128
00:09:27,440 --> 00:09:33,120
top but so we don't need it for ltx we're just going to temporarily mount it

129
00:09:32,080 --> 00:09:39,120
yes because for ltx we want it to be very pretty and pretty is not our specialty

130
00:09:37,839 --> 00:09:42,240
and like think about it it's not like when you sit in your car you don't have

131
00:09:40,880 --> 00:09:47,120
your dash in front of the windshield like we'll be able to see well enough

132
00:09:44,480 --> 00:09:52,160
look it's not it's gonna be like right in front like i know look if i could put

133
00:09:50,959 --> 00:09:57,120
it up a little bit with the windshield right here right this is like a supercar

134
00:09:54,000 --> 00:09:59,120
or something sure oh hot glue oof

135
00:09:57,120 --> 00:10:03,040
i'm just putting a little bit okay oh it has a bracket you know

136
00:10:00,880 --> 00:10:06,160
well now it's hot glued hopefully right side up too oh you can

137
00:10:05,120 --> 00:10:11,600
flip it all right there we go this is quick that's on there

138
00:10:09,519 --> 00:10:16,839
oh please don't hot glue that well just a little oh no just a dab okay i forgive

139
00:10:14,480 --> 00:10:20,560
you for choosing this car that's expensive because it's actually working

140
00:10:19,279 --> 00:10:23,120
pretty darn well yeah easy for you to say did you pay for

141
00:10:22,320 --> 00:10:27,680
it no but neither did you yes i did well

142
00:10:25,360 --> 00:10:31,000
linus media group incorporated who's that

143
00:10:32,399 --> 00:10:38,880
okay so now the battery we need the battery yep i'm not going to hot glue

144
00:10:36,720 --> 00:10:42,560
that this is a lithium polymer battery i would strongly recommend not hot gluing

145
00:10:40,560 --> 00:10:47,519
one of these anywhere you gotta rip it off just tears the cell

146
00:10:44,480 --> 00:10:50,720
in half so it's a massive fire yeah yeah

147
00:10:47,519 --> 00:10:52,640
spicy hey hey nice all right so the

148
00:10:50,720 --> 00:10:56,399
cooling fan is going is it super wide angle

149
00:10:54,399 --> 00:11:01,920
yeah actually holy crap i can see david right now really from where you are

150
00:10:59,279 --> 00:11:04,640
all right 720p right now so this is i think the highest

151
00:11:03,200 --> 00:11:10,240
quality setting it looks pretty good like the lowest latency setting you mean or no it's the highest quality one oh

152
00:11:07,440 --> 00:11:14,000
really so the highest latency oh okay how's your nausea

153
00:11:12,560 --> 00:11:19,040
um i mean the fact that you're moving isn't helping but uh do you want to put it on the

154
00:11:16,480 --> 00:11:23,519
ground i want to try it no i think i think i get to try the spoils of my

155
00:11:20,560 --> 00:11:23,519
labor where are the petals

156
00:11:24,160 --> 00:11:28,720
this is going to be kind of interesting watch me fall over

157
00:11:27,360 --> 00:11:32,399
okay is the hot soldering iron hot no okay i

158
00:11:30,399 --> 00:11:37,279
feel like i'm driving a jeep like

159
00:11:34,000 --> 00:11:38,640
oh man no way

160
00:11:37,279 --> 00:11:44,399
whoa oh my gosh dude the latency is so low

161
00:11:42,720 --> 00:11:48,000
uh so we think it's possible that we can insert an sd card right here in the

162
00:11:46,160 --> 00:11:53,120
occusync and record straight to this so you guys

163
00:11:49,680 --> 00:11:53,120
will see the full quality

164
00:11:54,240 --> 00:11:58,079
