you know it seems like lasers are everywhere in the tech scene these days
you got your laser mice your Laser Printers your beams by flow you got
those Dr Evil freaking laser beam jokes we keep making here on Tech Quicky in
spite of the fact that that movie was like 15 years ago but there's a new use
for lasers that hasn't become widespread
in the consumer Market just yet but one
that is already being deployed in commercial settings and may find its way
into your home in the near future laser
sex doll just kidding
projectors which have some advantages that make them A Cut Above existing
technology you see most modern projectors be they LCD or DLP use a
bright light source usually a bulb to
create white light which is then separated to create red green and blue
pixels which are ultimately blasted at
your screen and although this Arrangement functions well enough a lot
of the light from the projector bulb has to be filtered out to produce only the
red blue and green that is needed at any given time in fact less than
1 of the light generated by the projector actually makes it onto the
screen a higher-end laser projector on the other hand uses separate red blue
and green lasers instead of white light
which are combined by a lens into an image not only does this cut down
tremendously on power consumption but
the greater efficiency means that laser projectors can be made to be much
brighter than their bulb based counterparts without needing more
electricity than your Standard wall outlet can safely deliver lasers are
also typically made to emit light at one
only one precise wav length
corresponding to a specific color of light meaning that it's much easier for
manufacturers to build projectors with Arrangements of lasers at the correct
wavelengths to enable wider color gamuts
for more realistic and vibrant colors
you can learn more about different RGB setups and how they produce color right
about here and even moving beyond picture quality and efficiency laser
projectors are a lot more convenient not
only do laser light sources last much
much longer than bulbs Epson for example is saying that one of its home models
will last 30,000 hours which is long enough to
watch every episode of The Simpsons over 130
times they also don't need tons of time
to achieve Peak brightness when you turn them on so no more waiting around for
your projector to warm up oh and they turn off nearly instantly too of course
at this time as with any new technology
you'll be paying the dreaded early adopter tax epson's home model that I
just mentioned is going for $8,000 at the time of filming I mean
what kind of homes are they putting these things in with higher-end
commercial models going for many times
that additionally consumer focused laser
projectors often uh cheat a little bit
by only having two blue lasers one of
which hits a phosphor that separates the light into red and green another concern
is an effect known as speckle and if you've ever used a laser pointer you'll
probably be familiar with this speckle refers to how the dot on the wall kind
of shimmers if you look at it really close though well-made projectors should
be able to minimize this effect which is a good thing too because the last thing
you'd want when watching Techquickie on your fancy new projector is for me to
look even more ridiculous than I usually
do wait what
John tunnel bear VPN lets you tunnel to
one of 20 different countries letting you browse the internet and use online
services as though you are some Anonymous due or due debt from some
other country they have easy to use apps for iOS Android PC and mac and also a
Chrome extension and all you have to do when I say easy I really do mean easy
you download it install it and you like hit a button and then two things happen
your connection gets encrypted with AES 256-bit encryption and your public IP
address gets switched so you show up as though you are in a different country
this lets you bypass all the annoying details that typically come with using a
VPN for personal use no DNS no router settings no Port configurations nothing
like that they've got a top rated privacy policy and they don't log user
activity and the best part is you canot take my word for it you can try it for
free with 500 Megs of data with no credit card required then when you
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
suggestion for a future video and I'm I'm out of I'm out of hands but you'll
have to subscribe anyway even though I can't point at the button I mean it's
kind of over there I can kind of point at
both
