If you're interested in this story, it may be in print somewhere, but
it's also in this podcast that you can listen to online, with no
add-on apps:

Hint: They didn't do it themselves.
It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.
A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.
All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket as no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).

Download this Android App (Sensors Multitool) to read the sensors:

smartphone (everything you need to guide a missile to its destination):

The story is about the engines. N. Korea couldn't get a mid-range
rocket to fire reliably. All of a sudden, they're building ICBMs that
work.
The analysts recently realized why. The engines are Cold-War-Era
Russian -- possibly made in the old Russian heavy-engine factory in
the Ukraine.
I think you mean mean russia, not ukraine.
The factory is a holdover from the Sobiet days. It's in Ukraine.
there is no ukraine. there is only russia.
Blink blink...huh? Might want to tell that to the Ukrainians
Who? Are those the folks that resisted the russian takeover?
Nah..these people....
