10 UltiProp Clock (1)
This article gives you the key details that hopefully will
enable you to successfully build your own high-quality
clock, which is bound to draw admiring, envious cries of
"Wow!" from your guests. It's high time you too discover
Elektor's Ulti(mate) Prop(eller) Clock.
22 Multi I/O for FPGA Development Board (1)
Elektor's December 2012 FPGA is expanded with: GPS
receiver; temperature sensor; pressure sensor; RGB
color sensor; 2 x 16 character LCD; 4 pushbuttons;
4 LEDs; rotary encoder; 7 external digital expansion
pins; and 3 external analog inputs.
32 Home and Office Network Tester
The circuit presented here offers easy one-button
testing of common home and office networks, with
red-amber-green indication of the network status, and
any faults. The design is really simple, just a
microcontroller, an Ethernet interface, a pushbutton for
starting the test and status LEDs to show the condition
of the network. Still, it does do a lot more than a simple
40 USB Battery Tester
Testing batteries is a fairly common task among
electronics enthusiasts. Instead of using a complex
stand-alone meter, you can put the intelligence of a PC
to good use for this. Here we add a battery interface to
the general-purpose USB-I024 cable presented in a
previous edition of Elektor magazine.
48 Enter BeagleBone Black
Yet another platform has been released to the
embedded audience: the BeagleBone Black. Recently
we (finally) got one on our workbench. It looks like a
very promising platform with powerful hardware and a lot
of potential. Does it outperform the Raspberry Pi?
52 The Flowstone of Wisdom
There are many visual programming languages out
there, but Flowstone is one with a twist. Clemens
56 Joule Robbin' Hood
This circuit steals (energy) from the rich (batteries) and
gives it to the poor (plants).
58 DesignSpark Tips & Tricks Day #6:
after the layout
DesignSpark's online BOM and PCB quoting tools
enable you to find out how much it would cost to build
our example project. These tools can be a great time
