00:00:00,160 --> 00:00:07,080
you know it seems like lasers are everywhere in the tech scene these days

2
00:00:04,720 --> 00:00:13,880
you got your laser mice your Laser Printers your beams by flow you got

3
00:00:11,120 --> 00:00:18,520
those Dr Evil freaking laser beam jokes we keep making here on Tech Quicky in

4
00:00:16,359 --> 00:00:26,039
spite of the fact that that movie was like 15 years ago but there's a new use

5
00:00:22,960 --> 00:00:29,160
for lasers that hasn't become widespread

6
00:00:26,039 --> 00:00:31,080
in the consumer Market just yet but one

7
00:00:29,160 --> 00:00:38,000
that is already being deployed in commercial settings and may find its way

8
00:00:33,520 --> 00:00:41,079
into your home in the near future laser

9
00:00:38,000 --> 00:00:43,840
sex doll just kidding

10
00:00:41,079 --> 00:00:50,600
projectors which have some advantages that make them A Cut Above existing

11
00:00:47,840 --> 00:00:57,920
technology you see most modern projectors be they LCD or DLP use a

12
00:00:54,719 --> 00:01:00,280
bright light source usually a bulb to

13
00:00:57,920 --> 00:01:06,240
create white light which is then separated to create red green and blue

14
00:01:03,000 --> 00:01:08,439
pixels which are ultimately blasted at

15
00:01:06,240 --> 00:01:14,360
your screen and although this Arrangement functions well enough a lot

16
00:01:11,680 --> 00:01:20,040
of the light from the projector bulb has to be filtered out to produce only the

17
00:01:17,400 --> 00:01:25,960
red blue and green that is needed at any given time in fact less than

18
00:01:23,079 --> 00:01:32,159
1 of the light generated by the projector actually makes it onto the

19
00:01:29,320 --> 00:01:38,159
screen a higher-end laser projector on the other hand uses separate red blue

20
00:01:34,880 --> 00:01:40,720
and green lasers instead of white light

21
00:01:38,159 --> 00:01:46,680
which are combined by a lens into an image not only does this cut down

22
00:01:43,680 --> 00:01:49,399
tremendously on power consumption but

23
00:01:46,680 --> 00:01:54,439
the greater efficiency means that laser projectors can be made to be much

24
00:01:52,079 --> 00:01:58,880
brighter than their bulb based counterparts without needing more

25
00:01:56,640 --> 00:02:05,520
electricity than your Standard wall outlet can safely deliver lasers are

26
00:02:02,119 --> 00:02:08,640
also typically made to emit light at one

27
00:02:05,520 --> 00:02:11,239
only one precise wav length

28
00:02:08,640 --> 00:02:16,400
corresponding to a specific color of light meaning that it's much easier for

29
00:02:13,840 --> 00:02:21,760
manufacturers to build projectors with Arrangements of lasers at the correct

30
00:02:18,720 --> 00:02:24,800
wavelengths to enable wider color gamuts

31
00:02:21,760 --> 00:02:26,640
for more realistic and vibrant colors

32
00:02:24,800 --> 00:02:31,440
you can learn more about different RGB setups and how they produce color right

33
00:02:28,840 --> 00:02:37,239
about here and even moving beyond picture quality and efficiency laser

34
00:02:33,959 --> 00:02:40,640
projectors are a lot more convenient not

35
00:02:37,239 --> 00:02:43,440
only do laser light sources last much

36
00:02:40,640 --> 00:02:47,480
much longer than bulbs Epson for example is saying that one of its home models

37
00:02:45,360 --> 00:02:52,599
will last 30,000 hours which is long enough to

38
00:02:50,000 --> 00:02:58,280
watch every episode of The Simpsons over 130

39
00:02:54,400 --> 00:03:00,519
times they also don't need tons of time

40
00:02:58,280 --> 00:03:04,799
to achieve Peak brightness when you turn them on so no more waiting around for

41
00:03:02,640 --> 00:03:11,959
your projector to warm up oh and they turn off nearly instantly too of course

42
00:03:08,760 --> 00:03:14,319
at this time as with any new technology

43
00:03:11,959 --> 00:03:20,319
you'll be paying the dreaded early adopter tax epson's home model that I

44
00:03:17,480 --> 00:03:24,200
just mentioned is going for $8,000 at the time of filming I mean

45
00:03:22,760 --> 00:03:30,080
what kind of homes are they putting these things in with higher-end

46
00:03:26,440 --> 00:03:33,480
commercial models going for many times

47
00:03:30,080 --> 00:03:37,239
that additionally consumer focused laser

48
00:03:33,480 --> 00:03:40,360
projectors often uh cheat a little bit

49
00:03:37,239 --> 00:03:42,799
by only having two blue lasers one of

50
00:03:40,360 --> 00:03:49,720
which hits a phosphor that separates the light into red and green another concern

51
00:03:47,000 --> 00:03:54,280
is an effect known as speckle and if you've ever used a laser pointer you'll

52
00:03:52,120 --> 00:03:58,920
probably be familiar with this speckle refers to how the dot on the wall kind

53
00:03:56,720 --> 00:04:04,400
of shimmers if you look at it really close though well-made projectors should

54
00:04:01,519 --> 00:04:08,560
be able to minimize this effect which is a good thing too because the last thing

55
00:04:06,400 --> 00:04:14,200
you'd want when watching Techquickie on your fancy new projector is for me to

56
00:04:10,879 --> 00:04:18,880
look even more ridiculous than I usually

57
00:04:14,200 --> 00:04:18,880
do wait what

58
00:04:21,160 --> 00:04:28,440
John tunnel bear VPN lets you tunnel to

59
00:04:25,960 --> 00:04:33,039
one of 20 different countries letting you browse the internet and use online

60
00:04:30,520 --> 00:04:38,960
services as though you are some Anonymous due or due debt from some

61
00:04:36,120 --> 00:04:45,120
other country they have easy to use apps for iOS Android PC and mac and also a

62
00:04:42,680 --> 00:04:50,320
Chrome extension and all you have to do when I say easy I really do mean easy

63
00:04:47,560 --> 00:04:55,240
you download it install it and you like hit a button and then two things happen

64
00:04:53,080 --> 00:05:01,000
your connection gets encrypted with AES 256-bit encryption and your public IP

65
00:04:58,080 --> 00:05:05,960
address gets switched so you show up as though you are in a different country

66
00:05:03,400 --> 00:05:10,440
this lets you bypass all the annoying details that typically come with using a

67
00:05:07,800 --> 00:05:14,240
VPN for personal use no DNS no router settings no Port configurations nothing

68
00:05:12,560 --> 00:05:18,639
like that they've got a top rated privacy policy and they don't log user

69
00:05:16,600 --> 00:05:22,919
activity and the best part is you canot take my word for it you can try it for

70
00:05:20,560 --> 00:05:27,759
free with 500 Megs of data with no credit card required then when you

71
00:05:25,560 --> 00:05:33,520
decide to get a year of unlimited data you can save 10% by going to bear.com

Linus so thanks for watching guys like dislike leave a comment with a

73
00:05:35,240 --> 00:05:41,080
suggestion for a future video and I'm I'm out of I'm out of hands but you'll

74
00:05:39,360 --> 00:05:44,759
have to subscribe anyway even though I can't point at the button I mean it's

75
00:05:43,160 --> 00:05:46,960
kind of over there I can kind of point at

76
00:05:48,800 --> 00:05:51,800
both
