many newer Technologies really try to push the boundaries of what can be done
0:04
and bring the world something that it's never seen before but sometimes some of
0:09
the most useful stuff can just be a rehash of something that's actually very
0:14
old sometimes thousands of years old as
0:17
is the case with electronic ink although we've had paper and ink for a millennia
0:23
and can read just about anything we want on smartphones or tablets e-readers that
0:28
use electronic ink or e in instead of fully-fledged LCD screens are a very
0:33
popular choice but Luke why do people
0:36
even buy these things I mean your Android or iOS device can display ebooks
0:41
just fine so what's the point well to understand the advantages eink devices
0:46
have it helps to know a little bit about how they work a standard black and white
0:51
eink display is made up of millions of very small spheres called micro capsules
0:57
and are filled with black and white particles of pigment suspended in a
1:01
fluid white particles carry a positive electrical charge while black ones carry
1:06
a negative charge when you want to display something like that copy of 50
1:10
Shades that you only read after everyone's gone to bed your e-reader
1:14
applies different electrical fields to each micro capsule which in turn makes
1:19
either the white or black particles rise to the top creating text or an image
1:24
e-readers can also apply different charges to different sides of a single
1:29
micro capsu giving capsules a half white half black
1:32
or gray appearance which can be very useful in increasing resolution by
1:37
giving the edges to letters and other objects a smoother look the nice thing
1:41
about this ink suspended and goop system is that once the ink is pushed to the
1:46
top it stays there without needing any kind of power input the display only
1:50
draws power when you have to change something on the screen such as going to
1:53
the next page because simply leaving a page on the screen while you're reading
1:58
it uses no power on unlike an LCD display battery life for e-readers is
2:03
often measured in like days or even weeks instead of hours the downside to
2:08
this of course is just like with real paper you'll need some sort of external
2:12
light so you can actually read what's on the page some e-readers like the popular
2:16
Amazon Kindle paper white have included built-in LED lights for reading after
2:22
dark which works with a light guide to direct light evenly across the screen so
2:26
that it's easy for your eyes and convenient but also harder on your
2:30
battery even so the need for a light source is a worthwhile trade-off for
2:34
people who want easy portability less eye strain than a typical LCD screen and
2:40
the same awesome viewing angles you'd get from a gas station paperback and if
2:45
you want to do more than just read in black and white there's even color e in
2:49
technology that uses other color pigment particles and additional electrodes or
2:55
color filters on top of the display though it hasn't achieved widespread
2:59
adoption in in the consumer market yet thanks to its ability to hold images for
3:03
a long time without using electricity electronic ink is starting to find its
3:07
application in other things other than just e-readers even flash drives with
3:12
external eink displays that uh are able to display how much capacity is still
3:17
left inside iink SmartWatches that don't need to be charged nearly as often as an
3:22
Apple Watch or say Galaxy Gear there are lots of cool Concepts that may become a
3:27
reality as well such as e in credit cards that show your balance on the card
3:31
in real time and even large scale displays that can even change the
3:35
appearance of walls or Furniture pretty cool maybe one day you'll have an
3:40
electronic ink couch that can display scenes from your favorite Comics but
3:45
quickly switch off when it's time to bring a date
3:48
over speaking of switching quickly tunnel bear is a VPN that lets you
3:52
tunnel to 20 different countries allowing you to browse the internet and
3:56

4:04
have a Chrome extension just choose the country in the app turn tunnel bear on
4:09
and watch as your bear tunnels your internet connection to your new location
4:14
when you turn tunnel bear on two things happen your connection gets encrypted
4:17
with aes256 bit encryption and your
4:20
public IP address gets switched so you can show up as if you're in a different
4:24
country tunnel bear lets you bypass all the annoying details that typically come
