EDITORIAL
ardkernel had a busy month, and released several new
products that once again prove that they are the innovative
leaders in ARM micro-computing. Not only has Justin and
his team developed a new model for both the U and XU series, but
they have also created a tiny wearable Raspberry Pi-compatible
product that packs extra features.
The ODROID-VU is the USB touch-
screen that you’ve been waiting for!
A 9-inch model with 10-point multi-
touch input will be available in the middle
of August, and will not only work with the
ODROID family of computers, but is also
compatible with any Windows, Ubuntu and An-
droid machine that supports USB monitors.
The ODROID-W is a tiny version of the Raspberry Pi
that is intended for embedded, battery-powered applications such
as wearables and micro-controllers. It offers many new features not includ-
ed with the original Raspberry Pi, including removable USB ports, while remain-
ing very affordable.
And finally, the long-anticipated ODROID-XU3 is now available, and it is the
fastest ODROID ever made! It’s got everything the first-generation XU-E offers,
with some extra features:
•
•
•
Samsung Exynos5422 Cortex™-A15 2.0Ghz quad core and
Cortex™-A7 quad core CPUs
Mali-T628 MP6 GPU supporting OpenGL ES 3.0/2.0/1.1 and OpenCL
1.1 Full profile
Built-in energy sensors like the XU-E
H
We’ll be reporting more about the ODROID-XU3 in the October issue, but you
can get your XU3 now at the Hardkernel Store at http://bit.ly/1prRcPL.
In Linux kernel news, forum user @dsd gives us a report on the newest 3.17
kernel, which appears to now have ODROID support! Follow the original thread
at http://bit.ly/1s5Ov7z:
“Samsung has been doing a load of work upstreaming ODROID support into of-
ficial Linux. The first patches will go into Linux-3.17, although a load more patch-
es are needed to make this usable as a desktop system - might take a few more
releases before all patches are polished and included.
They are also working on upstreaming ODROID support into uboot, and they
have a nice feature there, they have found a way to automatically detect X2 vs
U2/U3 (by checking for the extra LED on the X2). So now uboot will automatically
pick the right device tree to load. That means one appropriately crafted “OS im-
age” will work for X2, U2 and U3.”
This issue has lots of information for hardware enthusiasts, including an in-
depth look at the different types of eMMC modules that Hardkernel makes and a
hands-on look at the powerful ODROID-SHOW. We also feature a guide to com-
piling your own kernel directly from the Hardkernel GitHub repository, a tutorial
for installing the light-weight Nginx web server on an ODROID, Nanik begins his
fascinating series on Android Application Development, and more!

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

I am President of
Respectech, Inc., a
technology consultancy
in Ukiah, CA, USA that I founded in
2001. From my background in elec-
tronics and computer programming, I
manage a team of technologists, plus
develop custom solutions for compa-
nies ranging from small businesses to
worldwide corporations. ODROIDs are
one of the weapons in my arsenal for
tackling these projects. My favorite de-
velopment 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.

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 comput-
er 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 own an ODROID-U3 which I use to
run a sandbox web server, live in the
California Bay Area, and enjoy hiking,
camping and playing music. Check
