SOFTWARE AND HARDWARE SOLUTIONS FOR THE EMBEDDED WORLD
w w w . m i k r o e . c o m
electronics & microcontrollers
Electromobile
This month’s focus is on automotive
and I believe the subject is covered
from a number of interesting angles.
The main project, for example, is
our new pocket-size OBD2 Analyser
with an extensive range of features.
Fully DIY to Elektor standards, the
instrument should be compatible
with all modern cars having OBD
connectivity. The built-in analyser will
faithfully read and display engine
data and any error codes you or
Edd the mechanic will want to clear
by matching repair work on the
vehicle. A graphic display ensures
a clear readout with plain-language
descriptions.
Those of you keen to use Google
Earth, a regular USB memory stick
and your PC to trace the actual route
you have followed by car, bike or on
foot will ind the GPS Datalogger on
page 30 an awesome project, if only
because it’s modular and the software
is ever so easy to adapt to personal
requirements. RU ready boots (or
wheels)… start logging!
The article on technological develop-
ments in electric cars concentrates on
energy sources available (and desir-
able) to power these vehicles. Which
sources are likely to be used by future
generations and what are all these
car and battery manufacturers doing
in their labs and on their test tracks?
Our ElektorWheelie self-balancing
electro scooter is covered in two
articles, one on the mechanical
assembly of the kit parts and your
careful irst attempts to ride the
vehicle, and another on a symmetri-
cal battery charger developed as a
premium alternative to the charger
normally supplied with the kit.
Of course, it’s not all vehicles and
batteries in this issue. With all
‘wheels’ safely parked or connected
to a charger, why not play a game
of chess against our ATM18 Mini
Chess Computer, or explore how an
R32C microcontroller drives an OLED
display.
Finally, I’m happy to announce a new
four-page section in Elektor called
E-Labs Inside
. These pages are irmly
positioned in the centre of the maga-
zine, just like the real Elektor Lab is
at the centre of our publications and
many of our products.
E-Labs Inside
reports on what our lab staff have
run into during the month — you can
expect to read about techie problems
and workarounds, equipment to drool
on, gizmos, burnt PCBs, techno-gos-
sip, tips and tools of the trade.
Happy reading!

Development of electric vehicles continues apace and
the enormous potential is clear. The key to the
success of electric vehicles lies, contrary
to early expectations, in lithium-ion
cells rather than in fuel cells.
This article has an overview
of current and future
technologies.
22 OBDAnalyserNG
The compact OBD2 Analyser in the June 2007 issue was an enormous success.
Now, it’s enhanced with a graphical display, Cortex M3 processor and an Open
Source user interface, the next
generation (NG) of Elektor’s
standalone analyser sets new
standards for a DIY OBD2
project.

“I’ll take it”
Yokogawa 2054 oscilloscope
This circuit can be used in any application where batteries are
charged and discharged. The circuit uses an LPC2103 microcontroller
connected to a 22-bit A/D converter to measure charge and discharge
currents, battery voltage, charge status (or available capacity) and the
instantaneous power being supplied to or drawn from the battery.
