Tech the Future
70 The Invisible User interface
     There is a strong trend toward usability in industrial design and in

     human-computer interaction. That primarily revolves around efficiency,

     effectiveness, safety and ease of use. In short, the user interface.

10 Embedded Firmware Library
     The modular EFL (Embedded Firmware Library) lets you write applications

     and modules that can be easily transferred from one board to another.

     Meaning you are no longer locked in to a single microcontroller

     Elektormanufacturer but rather just write for embedded Linux in general.
18 500 ppm LCR Meter (3)
     This month we get practical by covering the LCR Meter's circuit board

     assembly, parts lists, casing, and calibration in just 8 pages.
26 From BASIC to Python
     Python is a high-level language particularly associated with small computer

     systems such as the popular Raspberry Pi. The language is marked by

     clarity and conciseness. Gone are the brackets and semicolons which gave

     headaches in Pascal, С and Java, not to mention BASIC.
32 Taming the Beast (4)
     Once you start using virtually the entire FPGA chip for an application

     written in a hardware description language (HDL), examining the circuit

     inside the chip is difficult at best, so simulation is In order
Elektor40 Elektor Linux Board Extension (2)
     In this second and closing installment we look at the hardware and

     software interaction between the buttons and the LC display on the

     board — all with a view to learning how to program a well thought

     out menu.
43 OTA-based Triangular Wave Generator
     Although many applications of OTAs have been described, the basic circuit

     of a non-sinusoidal oscillator exploiting an OTA's specific advantages is a

     rare find. This design brief describes a combined triangular and rectangular

     wave oscillator with two OTA circuits.
46 BaroStick
     This USB barometric pressure sensor uses a Bosch sensor to measure the

     air pressure and temperature, after which this data can be displayed

     graphically and stored using Windows software,
50 Program Like the Professionals
     State diagrams see increasing use in software development. This article

     looks at how you can use them to make your programs more robust and

     free of bugs
