1
00:00:00,000 --> 00:00:06,879
the eagle-eyed among you have probably seen this LTT mousepad many times over

2
00:00:05,839 --> 00:00:13,040
the last oh i don't know six months

3
00:00:10,000 --> 00:00:15,120
six months that's cute past Linus

4
00:00:13,040 --> 00:00:19,600
we tried to launch this video eight months ago when we got our first

5
00:00:16,720 --> 00:00:24,080
shipment of desk pads but you you guys bought them all then we tried to launch

6
00:00:21,439 --> 00:00:28,400
the video again three months later and you bought them all again we have loved

7
00:00:26,800 --> 00:00:34,079
all of your feedback on the mousepads you guys can actually check out some reviews on the store page and finally we

8
00:00:31,760 --> 00:00:37,120
have our biggest restock yet but i can't promise you that they will last long

9
00:00:36,160 --> 00:00:42,559
anyway back to you past Linus what you haven't

10
00:00:39,600 --> 00:00:47,760
seen is the absolutely painful amount of r d that went into our attempt at making

11
00:00:44,879 --> 00:00:51,600
the best mouse pad we possibly could we didn't actually intend to make a video

12
00:00:49,760 --> 00:00:56,000
about this experience but we ended up learning so much that i felt that we had

13
00:00:54,480 --> 00:01:00,640
to share it with you here's how it went down

14
00:00:58,480 --> 00:01:04,239
this video is brought to you by ubico the ub key from ubico is a cost

15
00:01:02,559 --> 00:01:08,159
effective and easy to use two-factor authentication solution learn more about

16
00:01:06,080 --> 00:01:11,159
how to get 10 off yours at the link down below

17
00:01:18,320 --> 00:01:25,360
feast your eyes on LTT's first peripheral well sort of it doesn't look

18
00:01:23,520 --> 00:01:30,799
like it should have taken 15 months but the truth is we had no idea how much was

19
00:01:28,479 --> 00:01:34,560
involved in doing something like this right i thought it was going to be as

20
00:01:32,640 --> 00:01:38,880
simple as ask one of our lovely designers lloyd in this case to create

21
00:01:36,960 --> 00:01:44,079
some options for artwork get nick to contact some overseas vendors to

22
00:01:40,960 --> 00:01:45,600
requisition samples evaluate the samples

23
00:01:44,079 --> 00:01:50,399
and you know the communication of the suppliers and bippity boppity we print

24
00:01:48,159 --> 00:01:55,200
them well for starters about half of the requests for samples we sent out never

25
00:01:52,320 --> 00:02:00,000
even got a response their loss i guess and out of the many that we received a

26
00:01:57,680 --> 00:02:04,479
couple of weeks later only four of them weren't obviously garbage even out of

27
00:02:02,719 --> 00:02:08,479
those four none of them were perfect which was a big wake-up call for us

28
00:02:06,560 --> 00:02:13,599
there's varying materials print qualities and of course costs and as

29
00:02:11,360 --> 00:02:18,560
part of this process we also bought a whack of competing mouse pads for

30
00:02:15,360 --> 00:02:21,120
comparison but how do you compare

31
00:02:18,560 --> 00:02:27,280
if you have no data well aesthetic appeal and overall feel are easy but

32
00:02:25,200 --> 00:02:32,239
those aren't definitive rankings we wanted to actually quantify the

33
00:02:29,520 --> 00:02:37,200
performance of each sample pad so we needed data we challenged the jank

34
00:02:34,879 --> 00:02:41,440
master supreme alex to rig something up in the workshop and

35
00:02:39,280 --> 00:02:44,560
well i'll let him speak for himself this is the basic plan for our testing

36
00:02:43,440 --> 00:02:48,160
here you know just toss down a mouse pad

37
00:02:46,560 --> 00:02:52,959
and then we're going to use the little cnc rotor here to like wrap it around in

38
00:02:51,280 --> 00:02:58,000
a bunch of different ways to be able to precisely track

39
00:02:55,680 --> 00:03:01,040
how much the mouse is moving and then you know switch out the mouse pad throw

40
00:02:59,440 --> 00:03:06,560
another one in and it'll do its circles or whatever again

41
00:03:03,599 --> 00:03:09,920
only problem is i some have to attach this mouse

42
00:03:08,000 --> 00:03:13,760
to the router and i'm not entirely sure how to do it one

43
00:03:11,920 --> 00:03:16,959
of the problems is that you know if this goes up and down

44
00:03:15,280 --> 00:03:21,920
i don't know exactly how much force there is

45
00:03:18,560 --> 00:03:24,879
but i think it's uh

46
00:03:21,920 --> 00:03:30,480
like 960 newton meters which is it's way too much for a mouse

47
00:03:28,400 --> 00:03:34,000
to handle for sure you know before we do this i'm going to put on some safety

48
00:03:31,760 --> 00:03:37,360
glasses just in case something to be clear

49
00:03:35,280 --> 00:03:42,000
the scroll wheel on this mouse actually is broken so if we blow it up it's not

50
00:03:40,400 --> 00:03:48,799
the end of the world but you know we still don't want to

51
00:03:45,200 --> 00:03:48,799
that said let's give her

52
00:03:58,159 --> 00:04:04,959
seems to be working because we know that our cnc router's movement is

53
00:04:02,319 --> 00:04:09,360
sufficiently accurate and repeatable we tested it and we mostly trust the

54
00:04:07,439 --> 00:04:13,519
engineers at logitech who designed their hero sensor we can assume that on a

55
00:04:11,680 --> 00:04:18,560
mouse pad with perfect tracking characteristics the input path should

56
00:04:16,160 --> 00:04:22,960
match the output plot of our mouse's movement within experimental margin of

57
00:04:20,320 --> 00:04:28,080
error so the idea here is we tell the router to draw a perfect circle over and

58
00:04:25,840 --> 00:04:31,759
over again and we expect to see basically one circle in the software at

59
00:04:30,479 --> 00:04:37,120
the end we expect unfortunately the data was

60
00:04:35,199 --> 00:04:41,120
all over the place which is why we were moments from placing our bulk order only

61
00:04:39,440 --> 00:04:46,320
to end up delaying this product for another six months at the time we

62
00:04:44,080 --> 00:04:51,360
weren't sure what was to blame we had some theories that maybe our pressure on

63
00:04:48,320 --> 00:04:54,000
the mouse was too high or too low or our

64
00:04:51,360 --> 00:04:58,160
dpi settings were bad and that is something we ultimately had to fine-tune

65
00:04:56,080 --> 00:05:02,800
but what ultimately ended up solving the problem was a stiffer mount for the

66
00:05:00,400 --> 00:05:08,639
mouse how did we know that our testing rig was bad ah i'm glad you asked

67
00:05:06,080 --> 00:05:12,960
truthfully until fnatic contacted us claiming to have made the world's most

68
00:05:10,639 --> 00:05:16,800
accurate mouse pad i hadn't even given it a lot of thought i mean

69
00:05:14,800 --> 00:05:22,479
yeah isn't it the mouse that determines how well it tracks well sort of

70
00:05:19,680 --> 00:05:26,880
here's the thing an optical mouse works essentially by taking pictures

71
00:05:24,800 --> 00:05:30,240
many times per second of the surface that it's moving over

72
00:05:28,320 --> 00:05:35,280
some fancy math happens and it determines how far it's moved and in

73
00:05:32,400 --> 00:05:38,880
which direction by comparing the images which is great as long as the mouse

74
00:05:37,280 --> 00:05:42,960
exists in a world where the surface is perfect the pictures are perfect and all

75
00:05:40,960 --> 00:05:46,400
bodies are completely rigid but they're not

76
00:05:44,320 --> 00:05:50,960
so credit to fanatic they really did make a great mouse pad and studying it

77
00:05:48,880 --> 00:05:54,479
has taught us a lot about how to make ours better

78
00:05:52,720 --> 00:05:58,960
one thing we figured out even before using theirs as a point of comparison

79
00:05:56,400 --> 00:06:02,800
was that using a stretchy material could affect the tracking of the mouse

80
00:06:00,960 --> 00:06:08,479
think about it take this pad for instance it stretches in one direction

81
00:06:05,759 --> 00:06:13,759
but not in the other direction so when you move this way it kind of

82
00:06:11,520 --> 00:06:17,199
forms a bow wave ripple if you press hard enough into the pad

83
00:06:15,520 --> 00:06:21,600
not that you would do that but it's interesting nonetheless

84
00:06:19,280 --> 00:06:26,080
and while we're at it what if the bottom surface of the pad doesn't grip the desk

85
00:06:23,840 --> 00:06:31,440
properly i mean that's a ridiculous example we're looking at here but on a

86
00:06:28,080 --> 00:06:34,319
smaller scale that is a real factor

87
00:06:31,440 --> 00:06:39,199
armed then with our stiffer mount and a mouse pad that the manufacturer claims

88
00:06:36,880 --> 00:06:43,600
can produce this perfectly consistent performance we set to work trying to

89
00:06:41,520 --> 00:06:48,560
replicate their results from this point on creator warehouse's very own engineer

90
00:06:46,000 --> 00:06:52,720
kyle took the reins and in short order built us a new test rig using our prusa

91
00:06:50,880 --> 00:06:56,479
print farm for all the custom bits aluminum extrusion for the structure and

92
00:06:54,639 --> 00:07:00,880
a bunch of 3d printer hardware for the electronics it's pretty bare bones as

93
00:06:58,400 --> 00:07:05,039
far as a cnc machine goes it uses a ramps board for the electronics

94
00:07:02,639 --> 00:07:08,639
essentially an arduino mega some cheap nema 17 size stepper motors and gt2

95
00:07:07,680 --> 00:07:12,720
belts we couldn't know until it was built if

96
00:07:10,880 --> 00:07:17,280
it would be rigid enough for our testing but the name of the game here is if

97
00:07:14,639 --> 00:07:20,160
you're going to fail do it fast and do it cheap

98
00:07:18,240 --> 00:07:23,840
and conveniently once it was equipped with a new mouse holder that kyle

99
00:07:21,840 --> 00:07:29,120
reverse engineered from fnatic's picture of their test rig it did end up doing

100
00:07:26,400 --> 00:07:34,319
the trick it's not perfect perfect but given that logitech only guarantees 98

101
00:07:32,000 --> 00:07:39,840
accuracy for the hero sensor this test data from fanatics pad looks about right

102
00:07:38,160 --> 00:07:44,160
for our test the carriage moves the mouse around in a perfect circle 26

103
00:07:42,479 --> 00:07:48,560
times while we run a super simple pointer plotter on a laptop connected to

104
00:07:46,000 --> 00:07:53,520
the mouse which sorry in spite of this being a g305 is still a gpro wireless

105
00:07:51,680 --> 00:07:57,280
running the test this way tells us two things one

106
00:07:55,280 --> 00:08:01,840
if fnatic's test can be repeated by a third party which for all intents and

107
00:07:59,280 --> 00:08:04,879
purposes it can it's a great mouse pad and two

108
00:08:03,039 --> 00:08:08,879
whether or not we can match or beat their performance

109
00:08:06,479 --> 00:08:13,520
let's talk about that now in our attempt we sourced two new versions of the LTT

110
00:08:11,199 --> 00:08:17,759
pad from the same supplier now at the time we were mostly focused on the

111
00:08:15,440 --> 00:08:22,479
stretchiness of the material so we asked for one with two-way rather than one-way

112
00:08:20,400 --> 00:08:26,160
stretch so at least we'd have consistency to it

113
00:08:24,080 --> 00:08:31,120
and we also asked for one with no stretch and as it turns out

114
00:08:28,560 --> 00:08:35,440
funny story the first sample we had with the one-way stretch was actually far and

115
00:08:33,519 --> 00:08:39,680
away the most consistent when it came to tracking even better than the no stretch

116
00:08:38,000 --> 00:08:42,240
sample that our supplier couldn't even do full color printing on so it wouldn't

117
00:08:41,279 --> 00:08:46,240
even like look all cool we're still not quite on

118
00:08:44,560 --> 00:08:52,080
par with the data and fanatics marketing materials and i do still think that we

119
00:08:48,640 --> 00:08:54,640
might see an LTT pad pro in another year

120
00:08:52,080 --> 00:08:58,320
that manages to be absolutely perfect but

121
00:08:55,440 --> 00:09:02,800
we are close enough that anyone but the most professional of gamers is not going

122
00:09:00,720 --> 00:09:07,440
to notice the difference so all that was left at this point was to adapt our

123
00:09:04,640 --> 00:09:11,519
design for the 15 different sizes

124
00:09:09,200 --> 00:09:15,279
finalize the thickness we settled on three and a half millimeter by the way

125
00:09:12,959 --> 00:09:20,080
which i feel is a great balance between soft comfort and performance

126
00:09:17,600 --> 00:09:23,279
and await our final samples so

127
00:09:20,959 --> 00:09:26,959
this is it the LTT mouse pad

128
00:09:25,760 --> 00:09:33,680
take it in yeah it doesn't smell that good i cannot say how proud i am of our team

129
00:09:31,200 --> 00:09:37,839
for getting this done even for something as simple as a mousepad so many hands

130
00:09:36,000 --> 00:09:43,440
are involved in getting you guys the best possible swag and i hope that you

131
00:09:40,880 --> 00:09:46,880
enjoyed this long awaited piece of kit and you can see the whole lineup in our

132
00:09:45,440 --> 00:09:51,440
shameless promotion ShortCircuit unboxing video over on our other channel

133
00:09:49,839 --> 00:09:55,120
big thanks to ubico for sponsoring today's video ubico wants to make the

134
00:09:53,279 --> 00:09:59,279
internet safer for everyone so they created the yubi key it's a physical

135
00:09:57,519 --> 00:10:02,720
two-factor authentication key that helps you secure your online accounts it

136
00:10:01,040 --> 00:10:07,760
doesn't require batteries or a mobile connection and it's both crush and ip68

137
00:10:05,519 --> 00:10:11,760
water resistant it works out of the box with hundreds of popular business and

138
00:10:09,200 --> 00:10:16,079
personal apps like gmail twitter cryptocurrency exchanges and password

139
00:10:13,600 --> 00:10:19,760
managers and ub keys are super portable and work across tons of devices and

140
00:10:17,760 --> 00:10:24,000
operating systems like iOS Android Windows and mac it's time to take

141
00:10:22,000 --> 00:10:28,880
security seriously then so go beyond basic authentication and get 10 off your

142
00:10:26,399 --> 00:10:33,440
ubiq 5 series today by going to the link in the video description and using code

143
00:10:30,800 --> 00:10:37,760
Linus 10. all right video's over smash that link in the description and get one

144
00:10:35,120 --> 00:10:42,000
for yourself before they all sell out oh something to note by the way there

145
00:10:39,440 --> 00:10:46,160
are no limit switches to protect the cnc machine from traveling too far and once

146
00:10:44,320 --> 00:10:49,440
it powers on it has no idea where in space it is because it has no way to

147
00:10:47,760 --> 00:10:53,040
reference a home position so if you decide to use the files linked in the

148
00:10:51,440 --> 00:10:58,079
video description to make one for yourself just make sure you're a diligent

149
00:10:56,240 --> 00:11:04,760
operator because otherwise it could ruin itself pretty quickly but that won't

150
00:11:00,160 --> 00:11:04,760
happen to you you're a diligent operator
