there are plenty of things in the PC Enthusiast space that people love to
argue about AMD versus NVIDIA AMD versus
Intel AMD versus the 1980 US Olympic
hockey team okay but seriously aside
from these more practical concerns Aesthetics are just as important to many
people with there being no real consensus as to what looks good after
all what's tacky to one you proder might be Michelangelo's David to another so in
the past few years many component manufacturers have decided hey why not
just give people the ability to customize the look of their battle
station on a whim by adding RGB lighting
the RGB craze mostly started out on keyboards and mice but these days you
can pick up motherboards CPU coolers and
even RAM sticks that claim to offer Millions of colors but how does all of
this work and what features should you be looking for if you're going to trick
out your rig like The Griswalds Christmas tree well if you think back to
kindergarten you might remember that the three primary colors that combine to
form all the other colors are red yellow
and blue but this is true only for pigments
light works a little differently with the three primary colors of light being
red green and blue hence the name
RGB so when you fire up your favorite RGB device what's happening is that
separate red green and blue LEDs are
lighting up at different intensities to produce different colors as there
currently isn't a single LED bulb that can cycle through different colors on
its own so there are a couple of different ways that you can see this
principle in action if you set your favorite RGB device to White you might
be able to see all three colored LEDs
lit up if you look closely enough this is the same reason that when you get a
drop of water on your phone screen you can see a rainbow like effect on white
spots neat huh but how do these devices
adjust the brightness of each led to produce the color you want well usually
RGB gadgets work with a technique called pulse width modulation or pwm which you
can learn more about here although you might be more familiar with pwm as a way
to control your fan speed in your computer the same concept can control
colored LEDs so when you want to tell
your Control software boom I want yellow
it sends a signal to your device that tells both the red and green LEDs to
light up and blue to sit down and shut up and PW w m also controls something
called the duty cycle essentially how long the light is
on during each refresh a shorter duty
cycle means that specific color of LED
will be dimmer so if you want your keyboard to be a highlight or yellow
sort of color your green and red LEDs will have longer Duty Cycles while your
blue LEDs will have very short Cycles or just be turned off completely but
depending on its imp M mentation especially if the LEDs are refreshing
too slowly using pwm control with equal
parts of red green and blue to achieve white can result in a distracting
rainbow effect similar to what some people experience when watching a single
chip DLP projector to compat this some
manufacturers are introducing rgbw
strips that have entirely separate white
LEDs but enough about the nuts and B bolts what should you actually look for
when buying RGB gear well perhaps
unsurprisingly this depends almost entirely on your personal preference as
long as you buy something of good quality an important thing to research
is what kinds of customization a certain RGB product offers as many manufacturers
bundle software that can control RGB
effects which may or may not be to your liking Hardware Solutions also exist
such as NZXT Hue plus which serves as a
central hub for your systems LED strips and the RGB headers on certain
motherboards which provide similar functionality through software to take
things a step further unified RGB ecosystems like ASUS Aura and Razer
chroma are starting to become popular allowing you to sync up RGB effects on
your lighting strips your motherboard your memory your fans or even supported
peripherals and room lighting and
considering that RGB LEDs can often be configured to change colors depending on
important variables such as system temperatures your perfectly harmonious
RGB setup can actually be functional as
well just make sure you don't go too crazy want to browse a more open
internet and use online services as though you are in a different country
anonymously check out tunnel bear they've got easy to use apps for iOS
Android PC and Mac they also have a Chrome extension and turning it on is as
simple as clicking a button boom there
you go your bear tunnels your internet connection to a new location which means
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're in a
different country and it lets you bypass all the annoying bull crap that usually
comes with using a VPN for personal use no Port configurations DNS or other
router settings tunnel bear handles all of that stuff in the background they've
got a toprated privacy policy and the best thing is you can try tunnel bear
with 500 Megs of free data and no credit card required check it out at the link
in the video description and if you choose to get a year of unlimited you
