00:00:00.160 --> 00:00:07.080
you know it seems like lasers are everywhere in the tech scene these days

00:00:04.720 --> 00:00:13.880
you got your laser mice your Laser Printers your beams by flow you got

00:00:11.120 --> 00:00:18.520
those Dr Evil freaking laser beam jokes we keep making here on Tech Quicky in

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

00:00:22.960 --> 00:00:29.160
for lasers that hasn't become widespread

00:00:26.039 --> 00:00:31.080
in the consumer Market just yet but one

00:00:29.160 --> 00:00:38.000
that is already being deployed in commercial settings and may find its way

00:00:33.520 --> 00:00:41.079
into your home in the near future laser

00:00:38.000 --> 00:00:43.840
sex doll just kidding

00:00:41.079 --> 00:00:50.600
projectors which have some advantages that make them A Cut Above existing

00:00:47.840 --> 00:00:57.920
technology you see most modern projectors be they LCD or DLP use a

00:00:54.719 --> 00:01:00.280
bright light source usually a bulb to

00:00:57.920 --> 00:01:06.240
create white light which is then separated to create red green and blue

00:01:03.000 --> 00:01:08.439
pixels which are ultimately blasted at

00:01:06.240 --> 00:01:14.360
your screen and although this Arrangement functions well enough a lot

00:01:11.680 --> 00:01:20.040
of the light from the projector bulb has to be filtered out to produce only the

00:01:17.400 --> 00:01:25.960
red blue and green that is needed at any given time in fact less than

00:01:23.079 --> 00:01:32.159
1 of the light generated by the projector actually makes it onto the

00:01:29.320 --> 00:01:38.159
screen a higher-end laser projector on the other hand uses separate red blue

00:01:34.880 --> 00:01:40.720
and green lasers instead of white light

00:01:38.159 --> 00:01:46.680
which are combined by a lens into an image not only does this cut down

00:01:43.680 --> 00:01:49.399
tremendously on power consumption but

00:01:46.680 --> 00:01:54.439
the greater efficiency means that laser projectors can be made to be much

00:01:52.079 --> 00:01:58.880
brighter than their bulb based counterparts without needing more

00:01:56.640 --> 00:02:05.520
electricity than your Standard wall outlet can safely deliver lasers are

00:02:02.119 --> 00:02:08.640
also typically made to emit light at one

00:02:05.520 --> 00:02:11.239
only one precise wav length

00:02:08.640 --> 00:02:16.400
corresponding to a specific color of light meaning that it's much easier for

00:02:13.840 --> 00:02:21.760
manufacturers to build projectors with Arrangements of lasers at the correct

00:02:18.720 --> 00:02:24.800
wavelengths to enable wider color gamuts

00:02:21.760 --> 00:02:26.640
for more realistic and vibrant colors

00:02:24.800 --> 00:02:31.440
you can learn more about different RGB setups and how they produce color right

00:02:28.840 --> 00:02:37.239
about here and even moving beyond picture quality and efficiency laser

00:02:33.959 --> 00:02:40.640
projectors are a lot more convenient not

00:02:37.239 --> 00:02:43.440
only do laser light sources last much

00:02:40.640 --> 00:02:47.480
much longer than bulbs Epson for example is saying that one of its home models

00:02:45.360 --> 00:02:52.599
will last 30,000 hours which is long enough to

00:02:50.000 --> 00:02:58.280
watch every episode of The Simpsons over 130

00:02:54.400 --> 00:03:00.519
times they also don't need tons of time

00:02:58.280 --> 00:03:04.799
to achieve Peak brightness when you turn them on so no more waiting around for

00:03:02.640 --> 00:03:11.959
your projector to warm up oh and they turn off nearly instantly too of course

00:03:08.760 --> 00:03:14.319
at this time as with any new technology

00:03:11.959 --> 00:03:20.319
you'll be paying the dreaded early adopter tax epson's home model that I

00:03:17.480 --> 00:03:24.200
just mentioned is going for $8,000 at the time of filming I mean

00:03:22.760 --> 00:03:30.080
what kind of homes are they putting these things in with higher-end

00:03:26.440 --> 00:03:33.480
commercial models going for many times

00:03:30.080 --> 00:03:37.239
that additionally consumer focused laser

00:03:33.480 --> 00:03:40.360
projectors often uh cheat a little bit

00:03:37.239 --> 00:03:42.799
by only having two blue lasers one of

00:03:40.360 --> 00:03:49.720
which hits a phosphor that separates the light into red and green another concern

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

00:03:52.120 --> 00:03:58.920
probably be familiar with this speckle refers to how the dot on the wall kind

00:03:56.720 --> 00:04:04.400
of shimmers if you look at it really close though well-made projectors should

00:04:01.519 --> 00:04:08.560
be able to minimize this effect which is a good thing too because the last thing

00:04:06.400 --> 00:04:14.200
you'd want when watching Techquickie on your fancy new projector is for me to

00:04:10.879 --> 00:04:18.880
look even more ridiculous than I usually

00:04:14.200 --> 00:04:18.880
do wait what

00:04:21.160 --> 00:04:28.440
John tunnel bear VPN lets you tunnel to

00:04:25.960 --> 00:04:33.039
one of 20 different countries letting you browse the internet and use online

00:04:30.520 --> 00:04:38.960
services as though you are some Anonymous due or due debt from some

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

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

00:04:47.560 --> 00:04:55.240
you download it install it and you like hit a button and then two things happen

00:04:53.080 --> 00:05:01.000
your connection gets encrypted with AES 256-bit encryption and your public IP

00:04:58.080 --> 00:05:05.960
address gets switched so you show up as though you are in a different country

00:05:03.400 --> 00:05:10.440
this lets you bypass all the annoying details that typically come with using a

00:05:07.800 --> 00:05:14.240
VPN for personal use no DNS no router settings no Port configurations nothing

00:05:12.560 --> 00:05:18.639
like that they've got a top rated privacy policy and they don't log user

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

00:05:20.560 --> 00:05:27.759
free with 500 Megs of data with no credit card required then when you

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

00:05:31.039 --> 00:05:36.919
Linus so thanks for watching guys like dislike leave a comment with a

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

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

00:05:43.160 --> 00:05:46.960
kind of over there I can kind of point at

00:05:48.800 --> 00:05:51.800
both
