EDITORIAL
ur Robotics columnist, Chris, has released the next install-
ment of his Unmanned Ground Vehicle article, and shows
us in this issue how to interface with the motors and sen-
sors. We’re almost ready to start building our own version of this
awesome robot! We also take an inside look at GameStation Tur-
bo, the popular gaming and console
emulation OS image for the ODROID
X and U series. Our HPC columnists
Cooper and Anthony outline meth-
ods of keeping a High Performance clus-
ter of ODROIDs working smoothly with
an in-depth article about best practices
for HPC user and file management, and we
share a great home project where an ODROID-
U3 is powered using only solar energy, which stays
running even when the weather doesn’t cooperate.
Speaking of weather, the new ODROID Weather Board is Hardkernel’s
latest ODROID-SHOW peripheral, and bundles 6 sensitive environmental sensors
at an affordable price: UV index, barometric pressure, altitude, relative humidity,
illumination and temperature, and is fully compatible with the Arduino program-
ming system. Purchase your own Weather Board from the online Hardkernel
Store at http://bit.ly/1wtPdgP.
Hardkernel will be exhibiting at ARM Techcon on October 1-3, 2014 in Santa
Clara, California, USA. If you live in the Silicon Valley or Bay Area, register before
August 8th and receive a FREE pass to the Expo ($59 at the door) so that you

mentary early bird pass. We’d love to see you there!

I’m a computer
programmer liv-
ing and working in
San Francisco, CA, de-
signing and building web applica-
tions for local clients on my network
cluster of ODROIDs. My primary
languages are jQuery, Angular JS
and HTML5/CSS3. I also develop
pre-built operating systems, custom
kernels and optimized applications
for the ODROID platform based
on Hardkernel’s official releases, for
which I have won several Monthly
Forum Awards. I use my ODROIDs
for a variety of purposes, including
media center, web server, applica-
tion development, workstation, and
gaming console. You can check out
my 100GB collection of ODROID
software, prebuilt kernels and OS
images at

I am President of
Respectech, Inc., a
technology consultancy in
Ukiah, CA, USA that I founded in 2001.
From my background in electronics and
computer programming, I manage a team
of technologists, plus develop custom
solutions for companies ranging from
small businesses to worldwide corpora-
tions. ODROIDs are one of the weap-
ons in my arsenal for tackling these proj-
ects. My favorite development languages
are Rebol and Red, both of which run
fabulously on ARM-based systems like
the ODROID-U3. Regarding hobbies,
if you need some, I’d be happy to give
you some of mine as I have too many.
That would help me to have more time
to spend with my wonderful wife of 23
years and my four beautiful children.
Is counting the days
to his long earned
vacations! While that
doesn’t happen, he is working hard to
keep things going on smoothly at work
and play. And loony as always.

I am 31 years old and
live in Seville, Spain, and
was born in Granada. I have recently
become a father, and my son is now 5
months old. It is an incredible experi-
ence! A few years ago I worked as a
computer technician and programmer,
but my current job is related to quality
management and information technol-
ogy: ISO 9001, ISO 27001, and ISO
20000. I am passionate about computer
science, especially micro computers such
as the ODROID, Raspberry Pi, etc. My
other great hobby is mountain biking,
and I occasionally participate in semi-
professional competitions.
I am currently a
Digital Strategist and
Transmedia Producer
who specializes in online optimization
and inbound marketing strategies, so-
cial media directing and team coordi-
nation, as well as media production for
print, TV, film, and web. I also have
experience in graphic and website de-
sign, social networking management
and advertising, video editing and
DVD authoring. I own an ODROID-
U3 which I use to run a sandbox web
server, live in the California Bay Area,
and enjoy hiking, camping and play-
ing music. Check out my web page at
