00:00:07,440 --> 00:00:13,920
we've all been there you're up late working on a report

4
00:00:11,840 --> 00:00:16,880
playing some overwatch or just catching up on those netflix shows

5
00:00:15,599 --> 00:00:21,600
you're too embarrassed to tell anyone you watch you reach for your drink without looking

6
00:00:19,760 --> 00:00:26,400
and bam a torrent of mountain dew spills into

7
00:00:23,760 --> 00:00:31,199
your laptop and try as you might you never get it working quite right

8
00:00:28,560 --> 00:00:35,760
again the solution well i could say it's to be more careful next

9
00:00:33,680 --> 00:00:40,879
time but you guys know what you clicked on let's talk about the ruggedized

10
00:00:38,399 --> 00:00:47,280
devices out there that can survive way more than a bottle of soda

11
00:00:43,760 --> 00:00:49,120
companies like gtac panasonic and dell

12
00:00:47,280 --> 00:00:53,280
offer laptops that look less like what you're using to watch

13
00:00:50,719 --> 00:00:57,680
Techquickie in class right now and more like something the president might use

14
00:00:55,280 --> 00:01:03,440
to order a military strike but just how tough are they and what

15
00:01:00,640 --> 00:01:07,360
specifically allows them to survive in extreme conditions

16
00:01:05,280 --> 00:01:13,840
to start let's talk about how they resist two of the most common

17
00:01:09,680 --> 00:01:16,320
environmental hazards water and dust

18
00:01:13,840 --> 00:01:22,240
since water droplets and dust particles are very tiny fully ruggedized laptops

19
00:01:19,520 --> 00:01:25,360
employ strategies that go beyond screwing on an enclosure to keep them

20
00:01:24,560 --> 00:01:31,280
out the electronics inside can be sealed via

21
00:01:28,640 --> 00:01:36,159
techniques like injection molding which can not only protect against rain or

22
00:01:33,360 --> 00:01:40,479
water splashes but also allow prolonged use in very humid environments

23
00:01:38,640 --> 00:01:44,720
think about a soldier deployed in a tropical setting

24
00:01:41,840 --> 00:01:49,680
and sometimes engineers even fill enclosures with non-conductive silicone

25
00:01:47,680 --> 00:01:53,439
to ensure that nothing can touch your sensitive components a technique called

26
00:01:52,240 --> 00:01:58,240
potting potting is also an effective way to

27
00:01:55,600 --> 00:02:04,320
protect the electronics inside from our next hazards falls and vibrations

28
00:02:02,320 --> 00:02:09,920
you can think of it like wrapping a fragile item in bubble wrap before you

29
00:02:06,719 --> 00:02:11,840
ship it some ruggedized laptops don't

30
00:02:09,920 --> 00:02:16,720
fully pot their electronics though instead coating them in a thin layer of

31
00:02:14,319 --> 00:02:22,080
waterproof material and installing aluminum stiffeners which can also help

32
00:02:19,520 --> 00:02:28,080
to absorb a shock before it reaches a pcb or other sensitive component

33
00:02:25,520 --> 00:02:32,720
but what about heat doesn't all this sealing and reinforcing prevent heat

34
00:02:30,800 --> 00:02:36,160
from exiting the chassis great point

35
00:02:34,000 --> 00:02:41,040
it turns out that not only are some of these sealants chosen for their

36
00:02:38,560 --> 00:02:44,959
thermally conductive properties so the sealant itself can carry heat to a

37
00:02:43,519 --> 00:02:50,720
cooling surface but manufacturers can also place cooling

38
00:02:47,680 --> 00:02:52,480
fans strategically so that water can't

39
00:02:50,720 --> 00:02:59,280
hit the motherboard through outside vents usually this means placing a fan outside

40
00:02:56,560 --> 00:03:04,400
of the sealed inner electronics chamber or running heat pipes through the

41
00:03:01,440 --> 00:03:08,800
chamber wall and sealing up the cracks of course the simple fact that modern

42
00:03:06,640 --> 00:03:14,959
mobile processors run much cooler than they did a decade or two ago helps too

43
00:03:11,599 --> 00:03:18,959
our next hazard is less obvious heat is

44
00:03:14,959 --> 00:03:21,440
bad for electronics but what about cold

45
00:03:18,959 --> 00:03:27,040
devices working in extremely frigid conditions can end up with water

46
00:03:24,319 --> 00:03:31,680
condensing on their sensitive components causing them to short out

47
00:03:29,280 --> 00:03:36,239
for that reason some ultra rugged laptops even integrate small heaters so

48
00:03:35,440 --> 00:03:40,159
that let's say researchers studying penguins

49
00:03:38,720 --> 00:03:45,519
in the antarctic won't have their computer freeze

50
00:03:42,640 --> 00:03:51,519
at an inopportune moment okay so then penguin scientists sure but

51
00:03:48,879 --> 00:03:56,000
who else needs this kind of stuff well part of the reason that ruggedized

52
00:03:53,840 --> 00:04:01,920
computers exist at all is that they're designed to a military spec for use by

53
00:03:58,879 --> 00:04:04,239
armed forces and defense contractors

54
00:04:01,920 --> 00:04:08,799
some are even tested in acidic environments and against gunfire

55
00:04:06,560 --> 00:04:11,840
vibrations to ensure that they can withstand the harsh conditions of the

56
00:04:10,640 --> 00:04:18,560
battlefield the hardiest laptops are even built to

57
00:04:14,799 --> 00:04:21,199
an ip spec of 69k which you can learn

58
00:04:18,560 --> 00:04:26,560
more about up here meaning that not only are they fully dust proof they can also

59
00:04:23,520 --> 00:04:28,880
survive high temperatures and even high

60
00:04:26,560 --> 00:04:31,600
pressure spray downs if they need to be washed

61
00:04:30,240 --> 00:04:36,960
so pick some combination of these protections plus a toughened glass

62
00:04:35,520 --> 00:04:43,360
display which you can actually learn more about here or a touch screen that can be used with

63
00:04:40,639 --> 00:04:47,600
gloves on add powerful backlights and a high contrast panel technology so you

64
00:04:45,520 --> 00:04:51,360
can see what's happening on the screen even in bright sunlight and you got

65
00:04:49,600 --> 00:04:54,720
yourself a laptop that can go pretty much anywhere you can

66
00:04:53,280 --> 00:04:58,960
sounds great rugged laptops for all

67
00:04:57,360 --> 00:05:06,080
okay hold on a second ruggedized laptops do have some common

68
00:05:01,840 --> 00:05:08,479
issues a big achilles heel is io

69
00:05:06,080 --> 00:05:13,759
although ports can be protected with tight ceiling covers or plugs they are

70
00:05:11,120 --> 00:05:19,039
still a potential point of ingress for outside contaminants especially when you

71
00:05:16,560 --> 00:05:23,120
open them up to use them and while some manufacturers have somewhat mitigated

72
00:05:21,199 --> 00:05:28,000
this problem by keeping the i o electronics in a separate chamber from

73
00:05:25,680 --> 00:05:32,639
the main housing kind of like our fan example earlier this still means that

74
00:05:30,639 --> 00:05:37,280
your ports can be damaged in harsh conditions even if the rest of the

75
00:05:34,479 --> 00:05:43,120
system stays usable and unsurprisingly all this ruggedness can

76
00:05:40,080 --> 00:05:45,840
come at quite a cost especially for

77
00:05:43,120 --> 00:05:50,800
fully rugged military-grade models which can go for over ten

78
00:05:47,759 --> 00:05:53,840
thousand dollars each and that's without

79
00:05:50,800 --> 00:05:55,199
the latest core i7 and sli graphics

80
00:05:53,840 --> 00:05:59,199
cards but with all of that said if you're

81
00:05:57,280 --> 00:06:03,039
finding yourself constantly playing league of legends around your messy

82
00:06:00,800 --> 00:06:09,039
roommates who don't seem to care about what they spill or where it goes

83
00:06:05,520 --> 00:06:12,880
can you really afford not to get one

84
00:06:09,039 --> 00:06:15,440
tunnel there vpn it's super easy to use

85
00:06:12,880 --> 00:06:20,639
they've got apps for iOS Android pc and mac they've even got a chrome extension

86
00:06:17,919 --> 00:06:24,960
and all you gotta do is pick a country turn tunnelbear on and boom your

87
00:06:22,960 --> 00:06:30,960
internet connection gets encrypted with aes 256-bit encryption and your public

88
00:06:27,919 --> 00:06:33,199
ip address gets switched to some

89
00:06:30,960 --> 00:06:38,400
anonymous one so you know whether it's an advertiser looking to profit from

90
00:06:35,759 --> 00:06:42,880
your data or your isp wondering what exactly it is that you're browsing and

91
00:06:40,319 --> 00:06:48,400
downloading that all that stuff gets anonymized and tunnelbear

92
00:06:45,520 --> 00:06:53,199
gets past all the annoying details that typically come with using a vpn for

93
00:06:50,240 --> 00:06:56,960
personal use no port configurations dns router settings nothing like that it

94
00:06:55,039 --> 00:07:01,680
does it all in the background they've got a top rated privacy policy they

95
00:06:58,960 --> 00:07:06,880
don't log user activity and you can try it out for free with 500 megs of free

96
00:07:04,479 --> 00:07:10,800

97
00:07:08,800 --> 00:07:14,240
a year of unlimited data and save 10 percent on it while you're at it is go
